The Tabla Modular Shoring System is a high octane, high performance engi-neered modular panel shoring system. Tabla offers more erection, stripping and financial satisfaction than can ever be expected from conventional shoring systems. It begins with rigid panel construc-tion that enhances handling. The sharply honed Tabla Prop with its integrated drop-head puts you in control and helps

Introduction

The Tabla Modular Shoring Systemto ensure confident erection and ease of stripping, while back-propping remains undisturbed. These advantages result in a high rate of production. The Panel and Prop with engineered automatic wind lock provide job safety with a rigid interlocking system that prevents tipping during erection even without bracing. The system is designed to withstand wind loads near hurricane force.

When I started the design of the Tabla Modular Shoring Sys-tem, safety was the first and most important criteria. The well being of the workers who clearly would trust us was paramount. To those workers, we promise that we will never employ anything less than a 3:1 safety factor under live condi-tions, regardless of economic pressures.

Another decisive factor was to create the most economical system in the world. Thousands of design and trial hours have made this a reality. We have kept the end operation simple and safe. Currently we have over 2 million square feet, or 180,000 square meters of Tabla in operation and have poured over 200 million square feet, or 18 million square meters of concrete in North America and Europe.

Our customers have consistently erected Tabla panels and props up to 12’/3658 high with 14”/356 thick slabs and 11’/3353 high with 16”/406 thick slabs, including backshor-ing and reshoring, at a rate that exceeds 300 square feet, or 28 square meters per m an hour. Additionally, panels have been removed at a rate that exceeds 600 square feet, or 56 square meters per man hour in less than 2 days curing time, with a vastly reduced crew.

We promise to continue to faithfully improve Tabla, see-ing to it that our system is always Fast, Safe and Efficient. We introduced the second generation of Tabla at the 2007 World of Concrete in Las Vegas along with giving a “sneak peak” of our New Quick-release Reshore and the world’s first KD (knocked down) panel.

Another future release will be an aluminum prop that will provide a height up to 22’/6706, and most importantly, in stant adjustment. This will eliminate the now accepted screw, common in the market place today.

There is much more on the drawing board in the Tabla Engineering Department , so stay tuned, but first let us tell you about the Tabla Modular Shoring System.

Introduction

With Tabla, the Future is Now!

Paul A. GillespieTabla Inventor & Founder

The Tabla Modular Shoring System is an engineered modular panel shoring system which offers faster erection and stripping time than conventional shor-ing systems, directly increases financial return.

The rigid construction of the Tabla Panel enhances handling and durability. The Tabla Prop, with its integrated Drop-head, ensures confident assembly and ease of stripping from the floor below, while backpropping remains undisturbed.

The automatic wind lock design of the Panel and Prop prevents tipping during erection. The Tabla Modular Shoring Sys-tem has resisted gale force wind loads.

The inner rod of the Tabla Assembly/Disas-sembly Tool (ADT) has holes to accept a locking pin for adjustment.

The ADT knob is inserted into the hole in the inside strut of the panel. Once the tool is inserted, the panel is rotated (lifted) into the horizontal position and supports the panel until the Prop is installed.

To assemble and erect the Tabla ModularShoring System, only 3 basic components are required:

1 the Tabla Prop 2 the Tabla Panel 3 the Tabla ADT (Assembly/Disassembly Tool)

The Tabla System: Safe, Fast, Efficient

The Standard Tabla Shoring System is a unique system erected from the working floor up to a height of 12’/3658. With Prop Extension the system can be erected up to a height of 16’/4877. For higher floors see the Tabla Pioneer System on page 24. Tabla Shoring can accom-modate drop bands, drop heads and its design allows for all interruptions.

The Tabla Prop with its integrated Drop-head ensures ease of erection and stripping, while backpropping remains undisturbed. Tabla Props are avail-able in two sizes: 10’-0”/3280 mm and 12’-0”/3936 mm. In addition, there is a Prop Extension which, when coupled with a Tabla Prop, allows for additional height of 4’-6”/1476 mm. Our Prop fea-tures numbered adjustment holes, and an all new quick release reshore base.

Step 1 The Panel is hung onto the Prop.

Step 2 The Panel is rotated (lifted) to the horizontal position and supported with the ADT.

Step 3Next the Prop is slipped into position, locking into and supporting the Panel.

Erection continues by repeating steps 1, 2 and 3.

For maximum performance and detailed information, review this manual in its entirety.

Below are the three simple steps* to erecting the Tabla Modular Shoring Sys-tem from the safety of the working floor.

Please contact Tabla regarding the replacement of damaged components. Always use Genuine Tabla Components; never use substitutes.

The Tabla Panel features a specially designed Tabla Fastener which allows for the KD (knocked down) option for container shipping overseas. This also makes it a snap for qualified personnel to replace damaged components. The new design will work with existing Tabla components. In addition, the Tabla Panel features a powder coated, colour coded finish for quick identification between side and end rails of the panel. Simply match colours during erection.

* Tabla recommend a minimum of 2 operatives for the assembly.

Tabla Procedures

Erection

The minimum formwork crew size required to erect Tabla is two men*.The illustrated assembly procedure can be started anywhere on the working floor of the job site (i.e.: at column locations, middle of bay area, etc.).

Step 1Extend Props to required working height and insert the Quick-Release Locking Pin.

Step 2Prepare Bracing

Gates to build an “L” shaped tower

by assembling one Bracing Gate and two Props. Insert

and lock the Gate Brace to the Props

utilizing the attached Wedges.

Step 3 Attach a second Gate Brace at 90° to one of the props in the same man-ner as in Step 2.

Step 4 Tilt the Tabla

assembly into the upright position

and prepare to attach the third Prop to the free

end of the Bracing Gate.

Step 5 Square up the “L” shaped tower (3 Props and 2 Gate Braces).

Step 6 Hang the Panel

on the two Props making sure that

the legs of the Panel are firmly

seated in the cups of the Tabla Head Assembly. Rotate

Panel to allow insertion of ADT and continue to rotate upwards.

System assembly using Gate Brace*

Inset shows ADT inserted in Panel.

Step 7 With the ADT seat-ed into the Panel, step 6, rotate the Panel into the hori-zontal position and support the Panel until the forth Prop is installed.

Step 8 Place the fourth Prop under the

Panel corner socket and seat the Panel

into the Prop Head.

Step 10 With the ATD

seated into the Panel (step 6) and

the Panel rotated into the horizontal

position use the ADT to support the

panel temporaily until the next 2

Props are installed.

In general, all structures require lateral bracing or lateral support. The Tabla Shoring System is no different. Tabla Shoring derives its lateral stability under load and before loading by “blocking”, as construction proceeds, securely to the building’s structural elements, walls, col-umns, cores, stairwells, etc. Tabla users can also use Wall Brackets, Wall Beams

and Gate Braces. It is very important that the erector, understand the difference between blocking the system secure to the structure prior to pouring concrete, as opposed to the necessity to ensure that the system is laterally secured during the erec-tion phase. With proper procedure Tabla Shoring can free stand during erection.

PB Plastic Button

A button in the Prop Head is important to prevent the Prop tipping after Quick Release activation. The Plastic Button removes with the Prop Head. The Wood Button remains in the concrete and can be sheared off later if necessary.

WB Wood Button

Button in the Prop Head extends into the concrete to pre vent the Prop from slipping.

Activating Quick Release lowers the Prop Head along with the Plastic or Steel Button.

If the slab deflection does not allow the Prop to become “loose”, back down the Collar until the Prop is loose. After the entire level of Props are “loose” and the

slab has been allowed to accept its self weight, snug up the Props by turning the Collar.

Cantilever

10

Tabla Cantilever SystemTabla’s Cantilever technology maximizes efficiency and provides excellent safety on slab edges. Edge Cantilever con-struction is a potentially dangerous place to erect and work. Cantilevered Panels can create a great wind sail and it is estimated that uplift wind on tall buildings can be as high as 40 lbs per sq. ft/195 kg. per square metre or can create a force greater than 120 mph/190k/hr wind. Properly installed, the Tabla Cantilever System is designed to overcome these forces and when used correctly provides a safe working environment along with its unique fast and efficient erection.

Tabla Procedures

Use personal tie off safety lanyards when working with Cantilev-ered equipment.

Check drawings for exact details.

For Cantilevers greater than 60 degrees, consult engineering.

For unusual conditions consult the Tabla Engi-neering Department at 905-844-5300 [email protected].

Safety Note: Always be tied off when working with cantilevered panels.

Tabla Procedures

Ramps

The Tabla Shoring System has the unique ability to be used on ramps. To the right is a typical example of ramp erection.

Please note that terminus Shear Plate must be anchored to the concrete slab before a dead or live load is placed on Tabla Panels. Additional bracing is not required under sloped areas in single Prop arrangements of Tabla, provided that Shear Anchors or Shear Braces are firmly in place, and Panels are blocked at existing

walls and columns (see layout drawings). Shear load is accumulative when concrete is poured from top down. These calcula-tions are based upon uphill pours. Consult the Tabla Engineering Department if poured downhill.

For conditions not shown in this brochure and or the Engineering Bulletin, contact the Tabla Engineering Department (TED).

Concrete being pumped onto typical ramp constructed using Tabla Shoring.

When extreme conditions exist between slopes on the supporting slab and the supported slab, contact the Tabla Engi-neering Department.When the supporting floor is not at the same slope as ramp above, wedges must

be provided to maintain full bearing across the base plate.For special bracing details, consult the Tabla Engineering Department (TED) at (905) 844-5300 or [email protected].

Construction workers are using Side and End Filler Beams along with the Telescopic Beam they are holding to infill around a column at a project in Biola.

Side and End Filler BeamsSide and End Filler Beams allow 3/4” plywood to infill to the side of the Panel. The benefits of using Side and End Filler Beams are :

• Provide nailer strip for connecting 3/4” plywood;

• Eliminates notching of plywood around Post Shore Heads;

• Eliminates eccentric loading on Prop;

• Colour coded* for quick identification between Side and End Rails of Panels – simply match colours during erection.

Architectural Bridge Strips

The Architectural Bridge Strips are pre-cut specifically designed plastic strips, which are inserted between the Tabla Panel joints to limit concrete seepage. Tabla offers two types of ABS strips which allow you to decide what type of ceiling finish you desire. Option B and option A are inserted between the panels by foot after erecting the panels prior to rebar. The ABS is colour coded for quick iden-tification between Side and End Rails of Panels. Simply match colours to install.

In California, U.S.A., this ceiling finish (see option A image) is desired in garages by contractors, architects and owners. The concrete contractor has little to do to the ceiling after removing the Tabla Panels and Props exposing a symmetrical ceiling finish. The indentation is less than 1/16” deep and if desired can be covered with a skim coat over the recess.

Code of Safe Practices

Code of Safe Practices for erecting and dismantling vertical shoring

Reprinted with permission from page 168 of the Scaffold Industry Association Code of Safe Practices.If this notice is not readily available, cut and post on jobsite

It shall be the responsibility of all employers and users to read and comply with the following com-mon sense guidelines, which are designed to promote safety in the erection, dismantling and use of vertical shoring. These guidelines are not all inclusive nor do they supplant or replace other addi-tional safety and precautionary

measures to cover usual or unusual conditions. If these guidelines conflict in any way with any state, local, provincial or federal govern-ment statute or regulation, said statute or regulation shall super-sede these guidelines and it shall be the responsibility of each user to comply therewith and also to be knowledgeable.

These safety guidelines (Code of Safe Practice) set forth common sense procedures for safely erect-ing, dismantling and using shoring. However, equipment and shoring systems differ, and accordingly, ref-erence must always be made to the instructions and procedures of the supplier and or manufacturer of the equipment. Since field conditions vary and are beyond the control of the S.I.A., safe and proper use of shoring is the sole responsibility of the user.

guying or bracing when height exceeds 4 times the minimum base dimension and at lesser heights when stability is a concern.

K) Give special consideration totemporary loading. Areas where re-bar, material or equipment is to be stored temporarily may need to be strengthened to meet these loads.

L) Do not climb cross braces.M) Use special precautions when

shoring from or to sloped surfaces.N) Shoring loads are intended to be

carried by vertical legs. Loading of horizontal members may require special consideration. Consult your shoring supplier for allowable loads on horizontal members.

O) Avoid eccentric (off center) loads on U-Heads, top places and similar members by centering stringer loads on those members.

III. Guidelines for Dismantling Shoring

A) Do not remove braces or back off on adjustment screws or post shores until proper authority is given.

B) Dismantled equipment should be stockpiled in a planned manner and distributed to avoid concentrated loads on the partially cured concrete.

C) Use proper access equipment in the dismantling process.

IV. Guidelines for ReshoringA) Reshoring procedure should be

approved by a qualified engineer.

L) Erecting and dismantling of shoring requires good physical condition. Do not work on shoring if you feel dizzy, unsteady in any way or are impaired in any way by drugs or any other substance.

II. Guidelines for Erection and Use of Shoring

A) Provide and maintain a solid foot-ing. The sills or cribbing for shoring shall be sound, rigid and capable of carrying the maximum design load without setting or moving.

B) Always use baseplates. When sills or cribbing are used, base plates must be centered on them.

C) Adjusting screws shall be used to adjust to uneven grade conditions. Maintain all screw adjustments within the recommended height for the design load.

D) Plumb and level all shoring frames and single post shores as the erec-tion proceeds. DO NOT force braces on frames. Level the shoring towers until proper fit can be made. Maintain all shoring towers plumb and level.

E) Maintain the shore frame spacings and tower heights as shown on the shoring drawing. Where jobsite conditions require deviations from the shoring drawing, consult a qualified person.

F) Single post shores shall be stabi-lized in two directions. Bracing shall be installed as the shores are being erected.

G) Single Post Shores More Than One Tier High shall not be used. Where greater shore heights are required, consult the shoring supplier.

H) Adjustment of shoring to raise or lower formwork shall not be made during concrete placement.

I) If motorized concrete equipment is to be used, be sure that the shoring layout has been designed for use with this equipment and so noted on the layout, or drawing.

J) Use caution when erecting free-standing towers. Prevent tipping by

I. General Guidelines A) Post these shoring safety guide-

lines in a conspicuous place and be sure that all persons who erect, dismantle or use shoring are aware of them and also use them in Tool Box Safety Meetings.

B) Follow all state, local and federal codes, ordinances and regulations pertaining to shoring.

C) Survey the job site. A survey shall be made of the job site by a com-petent person for hazards, such as untamped earth fills, ditches, debris, high tension wires, unguarded open-ings, and other hazardous conditions created by other trades. These condi-tions should be corrected or avoided as noted in the following sections.

D) Plan shoring erection sequence in advance and obtain necessary access equipment to accomplish the work.

E) Inspect all equipment before using. Never use any equipment that is damaged or defective in any way. Mark it or tag it as defective. Then remove it from the jobsite.

F) A shoring drawing, consistent with the shoring manufacture’s recom-mended safe working loads, shall be prepared by a qualified person (or professional engineer where required), and used on the jobsite at all times.

G) Erect, dismantle or alter shoring only under the supervision of a qualified person.

H) Do not abuse or misuse the shoring equipment.

I) Inspect erected shoring: (a) imme-diately prior to concrete placement; (b) during concrete placement; (c) while vibrating concrete, and (d) after concrete placement until concrete is set.

J) Never take changes if in doubt regarding the safety or use of the shoring, consult your shoring supplier.

K) Use shoring equipment only for the purposed or in ways for which it was intended. Use proper tools when installing equipment.

Give a copy of this document to your workers and post it on the job site.

Additional notes from Tabla shoring.Always seek advice before starting erecting and carefully study provided shoring layout drawings and the Tabla Shoring System manual including safety notices. Users, always consult professional advise when in any doubt whatsoever or however small. This information does not purport to address the many job site conditions that can arise. Always stop work and ask for advice when in doubt. Compare for compatibility, all provided shoring drawings with jobsite conditions and structural & architectural drawings and specifications. Report immediately any discrepancies. Do not erect when in doubt.

These guidelines are provided by Tabla Shoring as common sense guide-line ONLY, to alert users and workers to (some of) the jobsite conditions to be avoided or professionally allowed for. This manual cannot suppose to address every possible jobsite condition which may arise – these conditions must be identified and addressed by site professional management and site safety.
