Introduction

The Tabla Modular Shoring SystemThe Tabla Modular Shoring System is a high octane, high performance engineered 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 construction that enhances handling. The sharply honed Tabla Prop with its integrated drop-head puts you in control and helps to 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. The standard Tabla Modular Shoring System is a unique system erected from the working floor up to a height of 166/5030. Tabla can accommodate drop bands, drop heads and its design allows for all interruptions. This brochure will show you the simplicity of our Shoring System as well as the minimalized number of components required for the erection process.

The simplicity of the Tabla system shown being erected, left and above, is the key to its speed and safety.

Introduction With Tabla, the Future is Now!The Tabla Modular Shoring System is an engineered modular panel shoring system which offers faster erection and stripping time than conventional shoring 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 System has resisted gale force wind loads.

When I started the design of the Tabla Modular Shoring System, 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 conditions, 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 backshoring 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, seeing 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 worlds 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, instant 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.

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

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

2 Panel

1 Prop

Paul A. Gillespie Tabla Inventor & Founder

3 ADT toolThe inner rod of the Tabla Assembly/Disassembly 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.

2

The Tabla System: Safe, Fast, EfficientBelow are the three simple steps* to erecting the Tabla Modular Shoring System from the safety of the working floor.

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 3

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

Erection continues by repeating steps 1, 2 and 3.

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 accommodate 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 available 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 features numbered adjustment holes, and an all new quick release reshore base.

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 Procedures ErectionSystem assembly using Gate Brace*Step 1Extend Props to required working height and insert the Quick-Release Locking Pin. Prepare 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. Tilt the Tabla assembly into the upright position and prepare to attach the third Prop to the free end of the Bracing Gate.

Step 2

Step 3

Attach a second Gate Brace at 90 to one of the props in the same manner as in Step 2.

Step 4

Step 5

Square up the L shaped tower (3 Props and 2 Gate Braces).

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.

Step 6

Inset shows ADT inserted in Panel.

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 7

With the ADT seated into the Panel, step 6, rotate the Panel into the horizontal position and support the Panel until the forth Prop is installed.

Place the fourth Prop under the Panel corner socket and seat the Panel into the Prop Head.

Step 8

Step 9

Hang the next Panel, as in step 6, and swivel to horizontal.

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.

Step 10

Definition of plumb(in any direction)

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 buildings structural elements, walls, columns, cores, stairwells, etc. Tabla users can also use Wall Brackets, Wall Beams

Bracing and blocking

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 erection phase. With proper procedure Tabla Shoring can free stand during erection.

Tabla Procedures Cantilever

Tablas Cantilever technology maximizes efficiency and provides excellent safety on slab edges. Edge Cantilever construction 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 Ramps

Concrete being pumped onto typical ramp constructed using Tabla Shoring.

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

Tabla Procedures Tabla Pioneer SystemHigh Floor Shoring SystemTabla Pioneer is a high floor shoring system which allows you to go to any height (subject to shoring tower specifications). It can be erected using Tablas Pioneer Head Assembly (Detail 1) or Tabla Prop (Detail 2). Either configuration can be attached to most standard shoring frames using Tablas Pioneer Connector. The system allows for stripping of the Panels while backshoring remains undisturbed. The new Tabla Quick Release Reshore Base (Detail 3) attaches to most screw-jacks using Tablas Pioneer Screw Adaptor. This allows the system to provide shoring, backshoring and reshoring using the same principal as Tablas Standard Shoring System. See pages 8 and 9 for more information regarding Backshoring and Reshoring.

Tabla Procedures Infill componentsTabla Infill Compoments

Tabla infill Components are designed to bridge between Panels or between Panels, walls and columns.

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 Beams

Side 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 :Side Filler Beam

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.

End Filler Beam

Place the Filler Beam into the Prop Cup and secure it using the Tabla Gravity Lock through accessory holes of the Panel and Filler Beam.

*Colours are reversed for metric sizes.

18

Telescopic Beams

Tabla Telescopic Beams are light weight and have an excellent load capacity. They are designed to take Drop Heads and Infil Strips from 30/914 to 100/3050. Telescopic Beams connect directly to the Filler Beams. These Beams are equipped with a graduated Bearing Plate at each end. Each Bearing Plate consists of 5 gravity bearing seats in 1 increments. By using the lowest seat the Tabla Telescopic Beam forms a flush deck using 3/4/19mm plywood infill. Other levels are for change in slab thickness and Drop Heads.

Tabla Procedures Architectural Bridge StripsThe 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 identification between Side and End Rails of Panels. Simply match colours to install.

ABS Strip Option A

Laying colour coded strips between panels.

ABS Strip A design profile 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 shoringGive a copy of this document to your workers and post it on the job site.I. General GuidelinesIt shall be the responsibility of all employers and users to read and comply with the following common 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 additional safety and precautionary measures to cover usual or unusual conditions. If these guidelines conflict in any way with any state, local, provincial or federal government statute or regulation, said statute or regulation shall supersede these guidelines and it shall be the responsibility of each user to comply therewith and also to be knowledgeable.

A) Post these shoring safety guidelines 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 competent person for hazards, such as untamped earth fills, ditches, debris, high tension wires, unguarded openings, and other hazardous conditions created by other trades. These conditions 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 manufactures recommended 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) immediately 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.

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.

K)

II. Guidelines for Erection and Use of Shoring

A) Provide and maintain a solid footing. 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 erection 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 stabilized 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 freestanding towers. Prevent tipping by

L) M) N)

O)

guying or bracing when height exceeds 4 times the minimum base dimension and at lesser heights when stability is a concern. Give special consideration to temporary loading. Areas where re-bar, material or equipment is to be stored temporarily may need to be strengthened to meet these loads. Do not climb cross braces. Use special precautions when shoring from or to sloped surfaces. 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. 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 Reshoring .

A) Reshoring procedure should be approved by a qualified engineer.

These safety guidelines (Code of Safe Practice) set forth common sense procedures for safely erecting, dismantling and using shoring. However, equipment and shoring systems differ, and accordingly, reference 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.
