A WORD ABOUT SAFETY
High productivity depends on safety; even a minor accident causes job delays and inefficiency, which run up costs. That’s why Symons
by Dayton Superior, in the design of its systems and products, makes the safety of those people who will be working with and near the
equipment one of its primary concerns. Every product is designed with safety in mind, and is tested to be certain that it will perform as
intended with appropriate safety allowances. Factory‑built systems such as these provide predictable strength, minimizing the uncertainty
that often surrounds “hand‑made,” “job‑shop” and “job‑built” equipment.
As a result, Symons by Dayton Superior products are your best assurance of a safe operation when used properly. To insure proper use, we
have published this application guide. We recommend that all construction personnel who will be involved, directly or indirectly, with the
use of this product be familiar with the contents of this guide.
As a concerned participant in the construction industry, Symons by Dayton Superior also recommends that regular safety meetings be held
prior to starting the forming operation, and egularly throughout the concrete placement, form stripping and erection operations. Symons
by Dayton Superior personnel will be happy to assist in these meetings with discussion of safe use of the quipment, slide presentations and
other formal safety information provided by such organizations as the Scaffolding, Shoring and Forming Institute.
In addition to the above meetings, all persons involved with the construction should be familiar and in compliance with applicable
governmental regulations, codes and ordinances, as well as the industry safety standards developed and published by each of the following:
American Concrete Institute
American National Standards Institute
The Occupational Safety and Health Administration
The Scaffolding, Shoring and Forming Institute
Because field conditions vary and are beyond the knowledge and control of Symons by Dayton Superior, safe and proper use of this
product is the responsibility of the user.
MAX-A-FORM® APPLICATION GUIDE

Introduction
Max‑A‑Form® is a steel faced and framed modular forming
system rated at a maximum of 1500 pounds per square foot
(psf) of concrete pressure. The modular panels are avail‑
able in a wide variety of sizes in order to make optimum
sized gang forms. Crane-handled Max‑A‑Form produces
excellent concrete finishes in both wall forming and selfspanning applications.
Sections I through III (One through Three) describe
Max‑A‑Form and its applications in the continually sup‑
ported mode. Self-spanning applications are presented in
Section IV and Max-A-Ply in Section V.
Basic Elements
A. Panels
1. Max‑A‑Form is a modular forming system made of
steel 3∕16" face plates and sections welded together.
The precise tolerances and built-in strengths gener‑
ate a high quality concrete finish. The panels are
designated by their width (the stiffener direction)
and length.
Max‑A‑Form components and accessories have been designed
for safe and efficient forming operations. It is recommended
that all construction personnel review and follow the appli‑
cable standards and practices established by the American
Concrete Institute, the American National Standards Institute,
the Occupational Safety and Health Administration, and the
Scaffolding, Shoring and Forming Institute.
2. Width: The panels are made in ten standard widths:
2'-6", 3', 3'-6", 4', 5', 6', 7', 8', 9', 10 and 12'. The
2'‑6" through 8' widths are designed for concrete
pressures of 1500 pounds per square foot (psf),
while the 9' and 10' panels are designed for 1200
psf. The 2'-6" through 7'-0" forms are 6½" thick,
and 8', 9' and 10' forms are 81/2" thick.
Caution: Max‑A‑Form components should be in‑
spected regularly for damage. Damaged equipment
must be replaced.
The procedures outlined in this Application Guide describe
standard application procedures for the Max‑A‑Form form‑
ing system. Since field conditions vary and are beyond the
control of Dayton Superior Corporation, safe and proper
use of the equipment is the responsibility of the user.

4.2'-0" Double Duty Panels. Panels that are 2'-0" in
length are designed so that they may be used ei‑
ther as a 2' long panel or a 2' wide panel. If they
are intended to be used as 2' wide panels they
must be ordered as such, so that extra tie holes
are added. Do not use 2' wide Double Duty Panels
in self-spanning applications. Standard 2'‑0" wide
panels can be used in self-spanning applications.

C. Wall Ties
1. Wall ties must be in compliance with industry
standards and safe practices established by the
American Concrete Institute, The American National
Standards Institute, The Occupational Safety and
Health Administration, and The Scaffolding, Shoring
and Forming Institute. Illustrations and capacities
of Dayton Superior Taper Ties and She-Bolt Ties are
given on the following page.
2. Project drawings indicate safe load capacities of
Taper Ties and She-Bolt assemblies, when both
outer unit and inner ties are supplied by Dayton
Superior Corporation.
3. It is the contractor’s responsibility to control
concrete mix and placement procedures to assure
that the maximum formwork design pressure is
not exceeded.
Note:The 96K Batter
Washer allows for a tie
swing up to a 14° angle off
of perpendicular
96K Taper Tie or 85K She-Bolt

4. Tie Installation Precautions:
a. Be sure that the correct thread size hex nut,
or cast contour nut is mated to all Taper Tie or
She‑Bolt out-unit threads.
b. Be sure that inner ties engage full thread depth
in all she-bolts. Full thread engagement is noted
as dimension “E” on illustration of She‑Bolt
capacities and thread dimensions.
c. Be sure that all ties using hex nuts with Cast
Bearing Washers or Flat Washers are installed
perpendicular to both form faces. Hex nuts
installed on ties not perpendicular to the form
face are subjected to eccentric loading that can
cause tie failure.
5. Batter Plate Castings, with mating Cast-Contour
Nuts, should be installed to support 50K ties that
are not perpendicular to the form face.
The 96K Batter Washer is used with the 85K She‑Bolts
or 96K Taper Ties.

6.a.Taper Tie Hammering Caps are available in two
sizes: 1" contour thread or 1¼" contour thread.
Taper Tie
b. The correct diameter and thread-type Hammer‑
ing Cap must be utilized during initial impact
release of embedded Taper Ties.
1/2" Nominal Recess
c. The Hammering Cap is positioned at the smaller
diameter end of the Taper Tie. The protruding
end of the Hammering Cap is then struck with an
8 lb. or heavier sledgehammer. All mushrooming
type impact damage is accumulated at the end
of the Hammering Cap, rather than the butt end
of the Taper Tie so as not to damage tie threads.
Note:The 1/2" nominal recess dimension is
critical for the following two reasons:
• It assures that all of the threads of the
nut portion of the Hammering Cap are in
mesh to withstand the transfer of sledgehammer impact to the Taper Tie.
• It provides a safe clearance between the
butt end of the Taper Tie and the striking
sledge-hammer.

Gang Assembly
Tools
Bolt-Up
The following list of tools will help construction personnel
erect Max‑A‑Form gangs and tighten nuts on bolts and ties.
1¼" Socket, ½" drive
Socket Wrench, ½" drive
Adjustable wrench, 12" length
Box or Open End wrenches for ties:
Symons Pry Bar
Oil for threaded parts
Spud Wrench
Site Selection
1. The gang assembly site should be chosen before the
arrival of the Max‑A‑Form equipment and should
meet the following criteria:
The site should be within reach of the crane
to both unload the truck and to position the
Max‑A‑Form panels for assembly.
The site should be as close to where the gangs
are going to be used as possible
 The surface area of the gang assembly site should
be reasonably flat and level.
 A large storage area next to the gang assembly area
is desirable in that it allows all like components
to be stacked together in an efficient manner.
2. Prepare the assembly site by cleaning away debris
and laying down 2x6 or 2x8 lumber. The lumber
should be positioned at all joints between panels
and at panel ends. The lumber provides a flat
plane and a common bearing surface for adja‑
cent panels. It also protects the panel face from
ground-contact damage.
WWW.DAYTONSUPERIOR.COM
1. Begin assembling by laying the panels face down
on the prepared surface in their proper locations.
Be sure that the tie holes in each panel are toward
the bottom of the gang in vertical-stiffener gangs.
Remember that opposite sides of walls are mirrorimage gangs, and the forms are assembled accord‑
ingly (so the tie holes match).
Hint: When assembling panel gangs, snug bolts
finger tight until gang is totally assembled. Then
wrench tighten after checking final alignment.
2.Use a spud wrench or drift pin to correctly align
bolt holes and form edges. Place the ¾" x2 " speed
bolts in the face side gauge line at one foot on
center in the 13∕16" x 1¼" slots in the side, top, and
bottom rails, as appropriate. All bolts should be
snug tight plus 1∕3 additional turn. This bolting
method is for Max‑A‑Form wall forming, not selfspanning applications.
3. Occasionally shims may be required for horizontal
and vertical panel joint alignment. If leakage is to
be reduced, install rubber gaskets at joints.
4. Additional speed bolts should be used in the second
gauge line to increase the stiffness.
5. The basic gang is complete when the forms are fas‑
tened together. However, the contractor may attach
appropriate accessories before raising the gang.
Caution: When gangs are more than two panels high,
it may be necessary to add strongbacks to the gang
before raising to the vertical position. Check with
your Dayton Superior representative for this condition.

A.Accessory Installation
All accessories are attached to the gang with the
¾" x 2" speed bolt.
1. Max‑A‑Form Top Tie/Lift Brackets
Lift Brackets are installed with three Speed Bolts
and nuts.
The following safety rules must be followed:
e. Gang forms should be adequately braced, reanchored, or otherwise secured prior to releasing
lifting mechanism.
2. Wide Walkway Brackets
A work platform supported by walkway brackets is
the recommended method of providing safe access
for working on the forms when pouring concrete, and
installing or stripping wall ties. The work platform
should be erected in accordance with the applicable
industry regulations and be equipped with guardrails,
midrails and toeboards along all open sides and ends.
Furthermore, walkway brackets should not be used
to support loads other than personnel.
Normal attachment of the walkway bracket to
Max‑A‑Form with the interior stiffeners in the vertical
position is done using two speed bolts. When the
interior stiffeners are horizontal, four Speed Bolts
are needed, two (2) in each leg.
a. Lift Brackets are the only attachment points for
crane rigging, and they must be properly spaced
and attached to the gang.
b. The safe load rating of the lifting bracket is 8,000
pounds at 5:1 Safety Factor.
c. The rigging must be designed by the contractor
to assure that any one Lift Bracket is not over‑
loaded. Spreader Beams are recommended for
all lifts with three or more lifting brackets.
d.A minimum of two tag lines must be used to
control the gang movement. Do not allow
personnel on or directly under any gang form
while it is being moved or suspended in air.
3/4" diameter x 2 Speed bolts
(3 required)
Caution: The ¾" bolt must always be positioned
through the hole of the horizontal and diagonal
members of the walkway bracket.
The Wide Walkway Bracket has a safe load rating
of 750 pounds. The brackets should be spaced 8
feet on center or less.

A simple four step procedure is used to set the
Max‑A‑Form gangs in place. In each of the steps
listed below refer to the accessory section of this
application guide for the proper use of necessary
accessories.
The first step is to attach the rigging to the first
gang to be positioned, usually the braced side of
the wall. The rigging is attached to the M/F Top
Tie/Lift Brackets, and the gang is raised, swung into
position, and lowered to its location.
Secondly, secure and anchor to a solid fixture.
Plumb the gang with the braces and remove the
crane rigging.

Next, attach the rigging to the Max‑A‑Form Top Tie/
Lift brackets on the gang meant for the opposite
side of wall. Raise and swing it into place, making
sure that the proper wall thickness is achieved (a sill
plate or chalk line helps). Be sure the ends of the
gangs line-up and/or that the tie holes are aligned.
Finally, secure the form to the previously braced
gang by attaching the top ties and installing the
through ties. (See the Tieing procedures section
of this guide for proper tie usage).
The above procedures can be used for single and
multiple lift gang forming conditions. The main
difference between single lift and multiple lift form‑
ing is the landing surface. On single lift forming or
the first lift of a multiple lift condition the landing
surface is usually a relatively large continuous sur‑
face. On the upper lifts of a multiple lift system,
the landing surface is two or more support jacks
or a ledge supported by same.
To minimize lifting stresses, a gang in the vertical
position should remain vertical throughout the job,
even while storing, to avoid the bending stresses
applied to horizontal joints by lifting the horizontal
forms to the vertical.

B. Gang Care and Placement
1. Care of Max‑A‑Form Gangs
The most important item of Max‑A‑Form gang care is
the use of a good form face coating, such as Dayton
Superior Magic Kote®. Magic Kote allows the forms
to strip easily and reduces concrete build-up. It also
protects the forms against rust and corrosion, and
reduces the form cleaning time between pours.
It is recommended that a visual inspection of the
Max‑A‑Form gang be performed between reuses of
the form. Look for loose bolts, bent or deformed panel
members, and broken welds. Although Max‑A‑Form
is a strong forming system, a gang is most apt to be
damaged by overloading and by mishandling. By
adhering to the design pressure specified on Symons
drawings or specifications, the Max‑A‑Form should
perform admirably. By stripping the Max‑A‑Form
after all the ties are loosened and by lifting and set‑
ting the formwork with minimal impact loads, the
Max‑A‑Form will hold-up for many pours.
The periodic removal of any build-up of concrete in
the recesses of the back side of the form is recom‑
mended. The build-up can add substantial amounts
to the weight of the gang.

C.Accessories and Applications
2 Bulkheads
1. Battered Walls
a. Battered forms are subjected to a vertical compo‑
nent of pressure. The amount of up-lift force will
depend on the degree of batter, height of wall,
and anticipated maximum concrete placement
pressure. A reasonable estimate of up-lift pres‑
sure must be made, so that necessary resistance
to up-lift can be installed; such as adding weight
or tieing down to the footing.
b. Since ties will not be perpendicular to both form
faces, Batter Plate Castings and Cast Contour Nuts
must be used with 50K ties and 96K Batter Wash‑
ers used with 85K She-Bolts or 96K Taper Ties.
These can be formed of wood, plywood, Steel-Ply,
Stay-Form™, and any combination thereof. Bulkheads
must resist concrete pressures while allowing rebar
penetrations. Unless there are many identical bulkhead
applications, a job-built form is usually acceptable.

inserted as sheathing. Studs may be required to
carry the design pressure.

Mismatched tie holes - When it is impossible to match
tie holes, a waler must be added to replace the top
or bottom rail as the load carrying member. Drill the
tie hole in the skin plate at the required location and
attach a 5" Versiform Waler to the panel. The tie can
then be inserted through the waler, through the tie
hole in the panel and through the tie box of the op‑
posing panel. The waler must run the entire length
of the panel. Sometimes an alternate tie location is
necessary in some places because of imbedded items
such as weld plates, pipe flanges, rebar, post tensioning
ducts, electrical fixtures and other mechanical devices.
The following illustrations show how to use a waler for
alternate tie locations.
Remember that holes drilled into the panel will result
in repair charges to rented equipment. Also a longer
tie is required to go through the additional thickness
of the waler.

In the illustration below, a 12" Max‑A‑Form panel is
bolted to the bottom of the vertical panel. This allows
the tie to be 15" above the floor. This method is useful

Max‑A‑Form Self-Spanning Applications
Generally, concrete forming systems are divided into vertical
and horizontal applications. Vertical forming systems are
designed to resist concrete pressure only. Since the weight
is carried by the ground or a previous pour. Horizontal form‑
ing systems, often called shoring are designed to support
concrete weight and live loads, but usually little pressure.
Forms that can resist lateral concrete pressures and verti‑
cal concrete weight together, are known as self-spanning
forms. Max‑A‑Form is such a form, and this type of form
has economies built into it. When shoring is impractical or
impossible, Max‑A‑Form is even more attractive.
A.Assembly
1. Select the assembly site, with the qualities men‑
tioned in the gang assembly section.
2. Soffit:
Layout the overall dimension of the soffit consider‑
ing the column openings, and place flat 2x lumber
sleepers at the form joints and at reasonable inter‑
mediate spacings. Level this support platform as
well as possible.
3. Place soffit face-down and bolt together. Bolt the
Outside Corner Angles to the soffit forms. Verify all
locations with the layout drawings. Install the¾"
bolts through the round holes, not the slotted
holes. Bolts are spaced 1' on center (unless noted
otherwise) on alternate gauge lines. All bolts should
be snug tight plus 1∕3 additional turn.
4. Place the Stability Beams on the soffit panels (un‑
less soffit is to be inset) and connect the beams
to interior stiffeners with 2 each Clip Angles and
Speed Bolts. Verify that all the dimensions and
beam cantilevers are as prescribed. Thrust bolts
should all be on the same side.
5. For sloped or flat inset soffits attach the Swivel
Jacks or the Rigid Jacks respectively to the interior
stiffeners as shown on the layout drawings. These
will be attached to the Bottom Ties later. Attach
the temporary lifting brackets and flip the soffit
forms. Realign the soffit assembly as required.
Another method of erecting the soffit is to build an
elevated work platform. Place the Stability Beams
on the platform. Place the soffit panels, face up, on
the beams. Bolt the Max‑A‑Form panels together
from underneath and attach the Stability Beams
using the Clip Angles.

6. Assemble the cap braces to the desired lengths and
attach the shoes and Brace Bracket. Attach the side
panels along one side of the soffit by bolting 1' on
center along the Outside Corner Angle. Brace the
side panels with the Pier Cap Braces bolted to the
Stability Beams. The cap brace should be between
30° and 60° from the horizontal. The Brace Bracket
is bolted to the Max‑A‑Form side panel near the top
(top third) of the form.
7. Align the side forms as they are installed. Insert
two Girder Bolts at the top and at the bottom of
all side form joints. All bolts should be snug tight
plus 1∕3 additional turn.
8. The rebar cage may be installed at this time. The
second side is erected in the same fashion as the
first. Sloped soffit forms should have both sides
installed before inserting the rebar cage.
Note:Adjacent
forms must be of equal
width in self-spanning
applications so that all
girder bolt positions
will align.

Ties and the Stability Beams to the side forms with
¾" bolts. Be sure that the Swivel Jacks and/or ex‑
tensions are between two bottom tie halves. Bolt
all necessary brackets and ties, and verify that all
connections are secure.
10.Install the rebar cage (if not done yet), and install
the end forms. Attach other accessories such as
lifting brackets, walkway brackets, chamfer strips,
and spreader beams.
Caution: Sloped soffits must be restrained horizon‑
tally by bolting through side panels.

B. Bottom Ties
2. Swivel Screw Jacks
Bottom Ties are required where soffits are inset or slop‑
ing. The maximum allowable spacing is 3'-0" on center
on soffits greater than 8'-0" wide and 4'-0" on center for
soffits 8'-0" wide or less. The bottom ties not only act
to hold the side forms together but also to support the
soffit either through Rigid Screw Jacks (for flat soffits)
or Swivel Screw Jacks (for sloping soffits). Bottom Ties
come in two halves with a Thrust Bolt assembly welded
to both. The total allowable load transferred from
the two screw jacks is 24,000 pounds (at 2:1 factor of
safety) divided equally between side panel connections
(12,000 pounds per side).
Two sizes of Swivel Screw Jacks are available to
support sloped soffits and non-vertical bulkheads.
The jacks must be perpendicular to the soffit panels.
The maximum swivel is 35° to vertical in a soffit
application. Two jacks maximum per bottom tie
allow a 3" to 12½" or 3" to 19½" adjustment range
for ties up to 7'-9"and 2" to 11½" or 2" to 18½" for
ties 9'-9" and longer.

1. Friction type support: Friction Collars are used for
this purpose. These collars are meant for round or
rectangular column applications and eliminate the
anchor requirements.
a. The round collars consist of two semi-circular
steel bands with mountings for 70K jacks and
Walkway Mounts. The jacks provide elevation
adjustments for stripping capabilities. The Cir‑
cular Friction Collar is rated at 96K total (48K
each side) up to and including the 36" diameter
size. Allowable working loads are reduced for
larger diameters. A Friction Collar requires four
bolts, four washers, and four nuts. The bolts
and nuts should be lightly oiled and tensioned
per Dayton Superior specifications.

Several types of devices are available for this purpose,
based on capacity requirements. Most common for
self-spanning applications are the Anchor Clamps,
70K Screw Jack, and 140K Screw Jack.
a.The Anchor Clamp will safely support 25,000
pounds at a 2:1 safety factor. It requires a
1½" diameter anchor bolt or thru rod and a
5" x 7" x ⅞" flat washer. The bolt or rod should
be a minimum distance of 6" from the top of the
previous pour. The anchor clamp is 21⅞" long
and has an adjustment range of 12 inches.
b.The Adjustable Anchor Clamp is also rated at
25,000 pounds at 2:1 safety factor, but has more
adjustment. It is 35" long and has an adjustment
range of 2213∕16". Anchor bolt and washer sizes
are the same as required for the anchor clamp.

c.The 70K 3 Position Anchor Bracket consists of
two major pieces: the 70K Anchor Bracket and
70K Screw Jack. The 3 position bracket allows
the Max‑A‑Form panel to be offset by as much
as 8" from the column or pier. The bracket is
fastened to the concrete with two 1½" diameter
bolts. The jack has a swivel head for sloping
conditions and adjusts from 10" to 15" above
the top of the anchor brackets.
d.The 140K Anchor Brackets are also a two piece
system, and the bracket comes in single and
two-position models. They both require two 2"
diameter bolts and the adjustment range of the
140K Screw Jack is 12" to 18" above the bracket.
The one position bracket allows up to a 2" form
offset and the two position bracket allows from
a 2" offset up to an 8" offset.
For all jacks, the loads must be framed into the
jack in such a manner that only vertical axial
loads are transmitted. Shims and special brackets
should only be used if all prying and shear forces
are adequately resisted. Please check with your
representative on these types of conditions.

Although the anchor brackets can support 70K and
140K respectively, the Max‑A‑Form panel cannot transfer
those loads without the use of Spreader Beams. If the
load to be transferred from the panel to the bracket
exceeds 25,000 pounds, then a spreader beam may be
required. Check with your Symons representative for
actual load limitations on different size panels.
Two size Spreader Beams are available. The 70K beam
is 3'-0" long and 8" deep. The 150K beam is 5'-11½"
long and 19½" deep. A Beam Brace is to be used at
either end of the Spreader Beams for added stability. It
attaches with ¾" bolts and nuts. Spreader Beams must
be bolted to panels and tied down to anchor brackets.
G. Thru Bolts and Imbeds
Imbeds are installed in the supporting concrete before
it’s poured. An imbed acts as a sleeve or guide for the
necessary thru bolts. They are usually secured to the
rebar or form to prevent movement.

H. Installation Sequence: Imbeds and Jacks
First, determine the location of jacks and thru bolts.
Refer to the layout drawings.
Max‑A‑Form
panels
Next, fasten the Imbeds to the rebar such that the two
pipes are horizontal along their axes and to each other.
Cap the ends of the Imbeds to prevent concrete block‑
age. Secure the caps to the formwork, for ease of
removal, with a screw.
After the forms are stripped, insert the Thru Bolts and
mount the Anchor Bracket. Install washers and nuts
to both sides. Adjust the jack elevation to the desired
level, and ready the Max‑A‑Form.
I. Placing Gangs
Sloped soffit

Spreader Beam
1.Lifting
Position the lift brackets on the Max‑A‑Form gang
so it lifts plumb and level, and does not exceed lift
bracket capacity. Use a lift beam to distribute lift‑
ing forces into the Max‑A‑Form panels in the most
efficient manner i.e. vertical loading.
After all the crane cable connections are made, lift
the Max‑A‑Form unit off the staging area about two
(2) feet and verify that the formwork is hanging
plumb and straight. If any problems are evident,
such as racking or bending, lower the unit to the
staging area and modify the lift arrangements.
Box units, often used for pier cap construction,
usually require spreaders and bracing to maintain
the desired shape. “L” shaped gangs (side + soffit)
may require counter weights for level lifting.

2. Form placement
Wall forms: Set the form on the previously installed
support equipment. Lap the previous pour approxi‑
mately two inches. While the crane is holding the
form, secure the formwork to the support system
and/or to the previous pour. Tie downs, ¾" rods
that hold the formwork to the support brackets,
should be installed at each support when the form‑
work is subjected to uplift and/or rotational forces.
The contractor can use clamping devices or other
methods to secure the desired alignment. Brace
the wall form before removing the crane rigging,
using H.D. wall braces, Pier Cap Braces, and guy
wires as required.

3. Pier cap: The best way to set a Max‑A‑Form pier
cap is as a unit. First, the entire “box” is lifted
and positioned over the pier stem(s). Then, set
the unit onto the support devices. Next, secure
the previously attached Spreader Beam to the sup‑
port bracket with 3/4" tie down rods. If the pier
stem can be lapped by the Max‑A‑Form, then the
forms can be drawn tightly to the pier or blocked
off it. When the formwork is secured to the pier
stem supporting system, then the crane rigging
can be removed.
Any large cantilevers or other severe loadings should
be stabilized with knee bracing and/or guy wires.
The contractor must secure all formwork to the
supporting devices and to near by fixed structures
to prevent movement before, during and after the
concrete pour(s).

J. Stripping
1. Wall forms and multi-lift
Attach the crane rigging to the lifting brackets and
take up the slack. Loosen and remove all ties. Break
the bond between the concrete and the forms. Do
not use the crane to break the bond. The gang is
then raised and carried to the next location.
2. “L + I” Shape Stripping Method
This stripping method is usually applied to a concrete
bent, which has a minimum of two (2) columns
and a uniform depth between the columns, having
a rectangular cross-section. It is strongly recom‑
mended to plan ahead how to strip the form, since
the stripping method influences both the design
scheme and the assembling sequence. Therefore
the assembling sequence will be included as a
part of a stripping operation. The “L + I” strip‑
ping method implies that the cross section of the
formwork has a “U” shape and it will be stripped
into two panels one as an “L” shape and the other
part as a “I” shape.

MAX-A-FORM® APPLICATION GUIDE
a. Assembling and Setting the Forms
1) Select and prepare the assembly site, which should
have easy access to a crane and a reasonably flat
surface. Place at least 12" high blocks approximately
at 6 foot intervals and level up the top.
2) Place the soffit panels face down and connect the
outside corner angles to the soffit panels as shown
on the layout drawing. Unless noted otherwise on
the drawing, the bolt connection is usually 12" on
center. Attach the Stability Beams to the soffit pan‑
els using the Clip Angles at the locations indicated.
While connecting the beams to the soffit, be sure
that the ends of the beams are aligned and the
Thrust Bolts are all on one side of the soffit, which
side will be stripped first as an “I” section.
3) Flip over the soffit assembly (now face up) and place
them according to the layout drawing. Make sure
all the dimensions and panel sizes are in agreement
with the drawing including the gaps around the
column area and the forms are properly aligned
along the length of the bent.
4) Start with the one side of the side forms by putting
a side panel on top of the outside corner angles and
place temporary braces as needed to hold in place.
Connect the side panel to the soffit forms with bolts
finger-tight at this time. Place the next side panel and
connect it to the previous side panel using only the
round holes between them. Insert the Girder Bolts at
both top and bottom of the panel joint, and connect
the side panel to the soffit as before. Continue this
step as many as needed for one complete side.
5) Attach the Pier Cap Braces between the Stability
Beams and the side panels erected. Tighten the bolt
connection once the entire side is aligned properly.
The Girder Bolts need not to be torqued.
6) If the rebar cage is to be flown with the form, then
place the rebar cage at this time using the proper
spacers around as required.
7) Attach the other side of the side forms, in a similar
way to the procedure described in step 4 above.
In addition to the step, the Top Ties need to be
installed at the locations shown on the drawing,
which will eliminate the necessity of the temporary
braces. However, if the rebar cage is not to be
flown with the form, it is recommended to install
the minimum amount of the top ties since they have
to be removed after setting on the final position
to put the rebars into.
8) Attach the Pier Cap Braces and tighten the connec‑
WWW.DAYTONSUPERIOR.COM
29
tions once the forms are all aligned. Connect the
rebar cage to the Top Ties, if the rebar cage has
already been placed.
9) Attach the Spreader Beams, if required, and the
Top Tie/Lift Brackets as indicated on the drawing.
Be sure the gusset plate of the beam falls into the
supporting jack location.
10)Attach the necessary accessories such as Walkway
Brackets.
11)Before setting the forms in place, it is necessary
to install the supporting jacks and brackets on the
columns at the elevations indicated on the drawing.
Finer adjustment can be achieved by the Screw Jacks.
12)Lift the form assembly and move slowly to the posi‑
tion. Once the form sits on the final position, install
¾" rods between the side panel and the supporting
bracket to resist the uplift force due to wind while
the crane is holding the form assembly.
13)Disconnect the Top Ties as required to put the rebars
into the form, if the rebar was not installed earlier.
Proper spacers are required around. Reconnect the
Top Ties.
14)Inspect the forms and dimensions again before pour‑
ing. Be sure the job built forms around columns are
sufficiently strong enough.
b. Stripping the Form
1) Connect the crane cables to the lifting brackets on
the “I” section side and remove any internal ties.
Unscrew the Thrust Bolts and disconnect the Stability
Beams on this side. Disconnect the Top Ties from the
other side panels. This means that the “I” section
side will fly with the Top Ties and the Pier Cap Braces
Unbolt the connection between the Outside Corner
Angle and the side panels. Remove the 3/4" diameter
rods used as tie downs to the anchor bracket. Strip
the “I” section side slowly.
2) Connect the crane cables to the lifting brackets on the
remaining side panels. Lower down the supporting
jacks to release the soffit forms from the concrete
and disconnect the tie downs. it may be necessary
to strip the job built forms around columns first to
facilitate the stripping. Strip the “L” section form
with the Pier Cap Braces and the Stability Beams
intact. Due to the center of gravity point, the sof‑
fit will not fly horizontally. Counterweight on the
walkways may be used to compensate this effect.
3)Remove supporting jacks and brackets from the
columns and install them for the next bent.

K. Hammerhead Stripping
2.Stripping
This stripping method is used on hammerheads or
pier caps supported by only one column or pier. The
forms are disconnected at a vertical joint and stripped
in two “U” sections. The two halves are cleaned and
reconnected on the ground, and then flown to the
next pour position.
a. Install blocks between top of pier cap and the
top ties on the left side forms.
b. Connect crane cables to the lifting brackets on
the right side forms.
c.Remove all internal and top ties on right side half.
Unbolt vertical joint connecting left and right
halves. Remove tie downs from anchor brackets
supporting right side forms and lower the screw
jacks. The weight of the forms should break the
bond with the concrete. If not separate forms
slightly by jacking between top tie lift brackets.
1.Assembling
To assemble and set the forms refer to the procedure
described in section A of “L & I” Stripping Method
on page 27.
d. Strip the right hand side U-shape (2 side forms
and soffit) and lower to ground.
e.Repeat steps 2 through 4 for the left side forms.
f. Clean, oil and reassemble forms on ground. Set

L. Hinged Soffit Stripping Method
c. Flip over the soffit assembly (now face up) and
place them according to the layout drawing.
Make sure all the dimensions and panel sizes
are in agreement with the drawing including the
gaps around the column area and the forms are
properly aligned along the length of the bent.
Soffit swing down clearance between column,
pier, friction collar or anchor bracket should be
at least 6".
Forms used in self-spanning applications may be stripped
as one unit if a hinged soffit is used. This method uses
the Stability Beams over the top of the forms and no
Bottom Ties. The soffit panels act as the bottom ties.
The soffits must not be inset or sloped. Once the forms
are assembled they are lowered over the rebar cage ei‑
ther on saw horses on the ground or on top of the pier.
1. Assembly and Setting the Form
d. Start with the side forms by putting a side panel
on top of the outside corner angles and place
temporary braces as needed to hold in place.
Connect the side panel to the soffit forms with
bolts finger tight at this time. Place the next
side panel and connect it to the previous side
panel using only the round holes between them.
insert the Girder Bolts at both top and bottom
of the panel joint, and connect the side panel
in the soffit as before. Continue this step for as
many as needed for one complete side.
a.Select and prepare the assembly site, which
should have easy access to a crane and a reason‑
ably flat surface. Place 2x lumber at soffit panel
joints and ends.
b. Place the soffit panels face down and connect
the outside corner angles to the soffit panels
as shown on the layout drawing. Unless noted
otherwise on the drawing, the bolt connection
is usually 12" on center. Attach the Heavy Duty
Hinge Assemblies to the soffit panels opposite
the Outside Corner Angles.

h. Bolt up soffit and secure rebar in forms. Attach
Walkway Mounts and Brackets.
i. Before setting the forms in place, it is necessary
to install the supporting jacks and brackets on
the columns at the elevations indicated on the
drawing. Finer adjustment can be achieved by
the Screw Jacks.
j. Lift the form assembly and move slowly to the
position. Once the form sits on the final posi‑
tion, install ¾" rods between the side panel and
the supporting bracket to resist the uplift force
due to wind while the crane is holding the form
assembly.
k. Install job built forms around columns. Inspect
the forms and dimensions again before pour‑
ing. Be sure the job built forms are sufficiently
strong enough.

2. Stripping the Form
a.Unbolt the Outside Corner Angles from the side
panels. use the crane or a come along to prevent
the soffit from swinging down suddenly.
b. Loosen (but do not remove) the following con‑
nections; both sides of the Stability Beams, Top
Ties and bulkheads. Any internal ties, box out
supports, anchor setting bolts and anything else
imbedded in the concrete should be removed
from the side panels.
c. Remove job built fillers from around columns.
d.Attach crane rigging and remove tie downs.
Shorten the Pier Cap Braces to pull the panels away
from the concrete pier cap and break the bond.
e. Attach tag lines to all four corners. Slowly raise
the forms carefully sliding it away from the pier
cap. Lower it away from the pier cap. Lower to
ground for cleaning and application of release
agent. Stability Beams, Top Ties, Pier Cap Braces
and bulkheads should all be repositioned and
bolts tightened at this time.
f. If rebar is set on piers for the next pour, lower
form over rebar cage onto Friction Collar or An‑
chor Bracket Jacks. Install tie downs and swing
up soffit panels. Plumb forms and tighten all
bolts before releasing crane. Install job built fill‑
ers, inspect forms and dimensions again before
pouring.

Max-A-Ply® Introduction
Max-A-Ply is a 3∕4" HDO plywood faced steel framed modular
forming system. The plywood face provides the convenience
of a nailing surface for boxouts, dowel bar substitutes,
inserts, etc. The Max-A-Ply panels have the same hole
pattern as Max‑A‑Form panels so the systems will bolt di‑
rectly together. All accessories and connections used with
Max‑A‑Form are also used with Max‑A‑Ply.

Safety Information
Improper Use of Concrete Accessories Can Cause
Severe Injury or Death
Read, understand and follow the information and instructions in this publication before
using any of the Dayton Superior concrete accessories displayed herein. When in
doubt about the proper use or installation of any Dayton Superior concrete accessory,
immediately contact the nearest Dayton Superior Service Center or Technical Service
Department for clarification. See back cover for your nearest location.
Dayton Superior products are intended for use by trained, qualified and experienced workmen only. Misuse or lack of supervision and/or
inspection can contribute to serious accidents or deaths. Any application other than those shown in this publication should be carefully tested
before use.
The user of Dayton Superior products must evaluate the product application, determine the safe working load and control all field conditions
to prevent applications of loads in excess of a product’s safe working load. Safety factors shown in this publication are approximate minimum
values. The data used to develop safe working loads for products displayed in this publication are a combination of actual testing and/or other
industry sources. Recommended safe working loads given for the products in this publication must never be exceeded.
Worn Working Parts
For safety, concrete accessories must be properly used and maintained. Concrete accessories shown in this publication may
be subject to wear, overloading, corrosion, deformation, intentional alteration and other factors that may affect the device’s performance. All reusable accessories must be inspected regularly by the user to determine if they may be used at the rated safe
working load or should be removed from service. The frequency of inspections depends upon factors such as (but not limited to)
the amount of use, period of service and environment. It is the responsibility of the user to schedule accessory hardware inspections for wear and remove the hardware from service when wear is noted.
Shop or Field Modification
Welding can compromise a product’s safe working load value and cause hazardous situations. Knowledge of materials, heat treating and welding
procedures is necessary for proper welding. Consult a local welding supply dealer for assistance in determining required welding procedures.
Since Dayton Superior cannot control workmanship or conditions in which modifications are done, Dayton Superior cannot be responsible
for any product altered in the field.

Many concrete accessory products that Dayton Superior manufactures are designed as part of a system. Dayton Superior
strongly discourages efforts to interchange products supplied by other manufacturers with components supplied by Dayton
Superior. When used properly, and in accordance with published instructions, Dayton Superior products have proven to be among
the best designed and safest in the industry. Used improperly or with incompatible components supplied by other manufacturers,
Dayton Superior products or systems may be rendered unsafe.
