Steel Shoring Frames

Steel Shoring Frames are made of high quality steel tubes and accessories which are galvanized or painted. Using the component and accessories, Steel Frames can be adapted to any geometry, steps and slopes.

10K Steel Shoring System is built to safely support loads of up to 4,535 kg (10,000 lb) with a Factor of Safety of 2.5:1 per CSA and SSFI.

Frame capacities vary, depending the number of tiers in height, the lengths of extensions, amount of bracing, whether inter-bracing has been used, and if there are any lateral or wind loads imposed.


Aluminum Shoring Frames

10K Aluminum Shoring Frames are made of a special high- strength aluminum alloy. Their strength / Lite-weight ratio greatly facilitates handling and erecting. The horizontal (serrated) ledgers make climbing safer and help to secure wood planks. Jet Locks are spaced at 605mm (2ft) centers to enable frames to be inter-braced with standard Cross Braces when erected more than one tier high. 10K Shoring System is built to safely support loads of up to 10,000 pounds/leg with a Factor of Safety of 2.5:1 per CSA and SSFI.

Frame capacities vary, depending the number of tiers in height, the lengths of extensions, amount of bracing, whether inter-bracing has been used, and if there are any lateral or wind loads imposed.

The normal testing configuration of the 10K Shoring System exceeds the requirements of both the CSA and the SSFI of the USA A tower, 3 tiers high, consisting of 6ft high frames, with Screw Jacks extended 12”, top and bottom, is loaded to failure. The load rating of the frames is then determined by dividing the failure load by the required Safety Factor.


Post Shores

The Steel Post Shores are primarily used in light construction applications and re- shoring. (Consult with TTF Engineering for design). 

150mm x 150mm Base / Top Plate (6in x 6in).

5mm (1/4in) steel plate including connection / alignment holes for adapting to u-heads, beams and other common post-shore applications.

Combined with stripping Handle, the Nut has 3 Additional Ears for use with hammers to ease in stripping the shore while under load.

Pins are of high grade steel, and come with attached safety cable to prevent loss of pins during transportation or on site handling.

Outer Tube is full length and continuous. Thread is cut into the outer tube providing a higher capacity, and equally important, far longer life expectancy when compared to products that are welded onto thinner walled tubes to reduce weight and cost.

TTF’s “Premium” Steel Post Shores are made of hi quality steel tubes and accessories which are galvanized to ensure many years of repeated use. Ideal of long term ownership and maximum stripping performance due to its labor saving “quick” release pin, making significant savings in the time to set, and strip the shore.


Screw Jacks

Our 48mm (1.9in) hollow steel shaft, 813mm (30in) long with 610mm (20in) of adjustment.

The  Screw Jack plates can accommodate T-Head bolts, designed for quick and easy locking into the continuous slot on our aluminum stringer beams. When the plate is to rest on mudsills or to be used with timber stringer material, instead of aluminum, it can be secured to the timber by nailing through the holes provided in the plate or a special U-Head can be attached to the Jack Plate.

The adjusting nut handles are “stepped” to allow the Screw Jack to be solidly centered in either an Extension Tube or the frame leg, thus assuring straight alignment and rigidity.


Cross Bar

• 9/12” (14.3mm) hole.
• Sizes are stamped on ends.
• Pre galvanized tubes for long life and durability.


Aluminum Beams

The Aluminum Beam is the most versatile and widely used element in all shoring and formwork applications. In Shoring, it is used as the joist and stringers on top of our various frame systems, as well as the joist for our fly forms systems. For wall forming, the beams are used as joist either in a vertical, or horizontal configuration, while our strongbacks complete the system by providing the backbone of the formwork, allowing tie-rod connections to be made.

Beams are made from high grade structural alloy 6351-T6, which has greater strength that 6061-T6 alloy. Reinforced side flanges resist bending and retain beam clips.

Eliminate up to 1/3 of the horizontal members and as much as 1⁄2 of the vertical support, using aluminum beams instead of wooden ones.

Reduced weight of each beam combined with fewer structural members minimizes worker strain. Lower worker fatigue means higher worker efficiency and lower cost.

All beams are available in standard lengths of 4’, 5’, 6’, 7’, 8’, 9’, 10’, 10.6’, 12’, 13’, 14’, 16’, 18’ and 20’ with plastic or wood inserts


Beam Clips

The Beam Clip plate is made from specially-formed high-strength aluminum.

When the Beam Clip is assembled with T-bolt and hex nut as an assembly the bolt is crimped to prevent loss of the nut. The assembly is used to tie aluminum beams securely together.

Some other uses of the Beam Clip are:

a) Securing aluminum beams to standard steel Post Shores.

b) Securing joists to stringers on Wall Forms or rolling tables, or when a sloping slab is to be poured.


Additional Information

Aluminum Beams

MORE VERSATILE: Plastic or wood insert allows for nailing or screwing down plywood decking. Less subject to damage than wooden beams. Reusable. It all adds up to less inventory, less storage, lower transportation cost, and lower carrying costs.

MORE ECONOMICAL:12.7mm (1⁄2″) T-bolt slots provide for easy fastening of beams and stringers to their supports or to each other. Your workers will be more productive and the lower labour costs will be reflected in your bottom line.

STRONGER: Reinforced side flanges resist bending and retain beam clips. Employees spend less time repairing and more time working.

SAFER: Wider flanges resist overturning. Fewer accidents and injuries mean less employee downtime and lower insurance costs.

The Aluminum Beams have many other advantages over competing beams. Our designs save time on the job and reduce maintenance. Please refer to our load charts for capacities. Generally speaking, the beams carry more load and usually cost less.


Lateral Bracing

GENERAL RECOMMENDATIONS

• Lateral bracing shall be designed by a qualified structural engineer in accordance with National Building Codes and Local regulations.

• Towers exceeding the allowable height-to-base ratio shall be braced in both directions.

• Clamping of external bracing shall be at the intersection of vertical legs with the bracing tube.

• Do not connect bracing tubes to the frame’s ledgers.

• Whenever possible, the horizontal bracing shall be tied to permanent structures such as walls, columns.

• If no walls or columns are present, guying can be used as an alternative.

IMPORTANT:The temporary shoring structures shall be structurally analyzed to include all lateral loads including wind pressure, lateral loads due to motorized equipment, lateral load components due to inclined supports or live and dead loads, etc.

If required, consult TTF Systems Engineering Department.

As a Guideline: In Canada, horizontal bracing is placed at a height not exceeding 3 times the minimum base width. In the USA, except for some states, the rule is 4 times the minimum base width.

BE SURE TO CHECK ALL RELEVANT CODES.


SLOPPING SURFACES

• Lateral bracing shall be designed by a qualified structural engineer in accordance with National Building Codes and Local regulations.

• Towers exceeding the allowable height-to-base ratio shall be braced in both directions.

• Clamping of external bracing shall be at the intersection of vertical legs with the bracing tube.

• Do not connect bracing tubes to the frame’s ledgers.

• Whenever possible, the horizontal bracing shall be tied to permanent structures such as walls, columns.

• If no walls or columns are present, guying can be used as an alternative.


MAINTAINING FULL LEG LOAD

TTF  recommends that additional lateral stability bracing be installed at the mid-height of 7.3m(24ft) to 9.1m(30ft) high towers, and every 5.5m(18ft) [3 frames] if higher.

The towers should be sufficiently diagonally braced to prevent lateral movement, where the walls or columns are not poured before the deck.

Tube-and-clamp can also be used to provide additional stability bracing in both directions. Clamps should be used at every intersection of the bracing tubes with the frame legs.

The horizontal tubes should, if possible, be tied to or butted against the permanent structure (such as walls or columns).

Note: If towers are inter-braced and sufficiently Cross Braced between towers, tube-and- clamp may only be needed in one direction or may not be required at all.

Consult TTF Systems or an experienced layout engineer. Guying can also be an alternative for providing additional stability bracing

DO NOT CLAMP TO RECTANGULAR HORIZONTAL FRAME LEDGERS.


Safety Guidelines

Fall Preventions

All the erection crew must be equipped with harnesses and double lanyards.

Harnessed should be safety attached to horizontal members of the frame in the locations shown on diagram. 

Note: It is very important to note that the hanging points should be between the knee brace and the frame leg – indicated in the attached sketch. It should never be from the middle of the frame.
