Design Codes Kwikstage Shoring is a modular system primarily for use in temporary works and as such complies with the following codes:- BS 449:1969 inc. 1989 Amendment - Specification for the use of Structural Steel in Buildings BS 5975:2008 - Code of Practice for Temporary Works Procedures and the Permissible Stress Design of Falsework Eurocodes The equipment is currently being assessed to Eurocodes. Strengths relating to these codes will be published in a future revision to this document. Please refer to Mabey Hire Ltd. engineering team for the latest information. Safe Working Loads The casting and wedge fitting at the end of a Shoring Tie combine to create a very rigid connection between the horizontal and vertical members of the Kwikstage Shoring System. The rigidity enables improved load capacities to be obtained in standards compared with those achievable when Kwikstage Ledgers or Propping Ties are used. A minimum of two Shoring Ties connected at right angles at set positions up a standard provide sufficient restraint to allow these increased loads to be justified. An extensive and exhaustive testing programme has achieved verification of theoretical load capacities. Shoring Ties are normally placed in the highest and lowest possible sets of “V” pressings on a standard. In certain cases the second set of “V” pressings may be used, but allowable loads are much reduced. Product Use For the handling and use of Kwikstage Shoring, please refer to Sections 3.0 to 6.0. 1.0 Introduction TECHNI CA L DA TA SHEET Kwi kst age Shor i ng Document Ref: TDSKSS Page No. 4 of 21 THE I NFORMATI ON ON THI S DATA SHEET REMAI NS THE PROPERTY OF MABEY HI RE LTD.

The two types of standards are identified by, “Standards” which have a device (spigot) at one end to allow the standards to be connected end to end, and an “Open Ended Standard” which allows the use of U Heads and Base J acks at either end. Each type of standard has “V” pressings attached, 4No. around the circumference of the tube, at right angles to each other, and at 495mm vertical centers’ along the tube. The “V” pressings allow the Shoring Ties to be connected to the standards. 2.1.2 Section Properties Part No. Length (m) Weight (kg) End Type KS-SEU/1.48 1.473 7.9 Spigot KS-SEU/1.98 1.981 12.0 KS-SEU/2.97 2.972 17.4 KS-OEU/0.99 0.991 5.3 Open Ended KS-OEU/1.48 1.473 7.9 KS-OEU/1.98 1.981 12.0 Outer Diameter Nominal Wall Thickness Mass per Linear Metre Cross Sectional Area, A Moment of Inertia, I Radius of Gyration, r Modulus of Elasticity Design Strength (mm) (mm) (Kg/m) (cm 2 ) (cm 4 ) (cm) (N/mm 2 ) (N/mm 2 ) BS EN 39:2001 Steel Tube 48.3 +/- 0.5 4.0 4.37 5.57 13.8 1.57 210,000 235 2.0 Section Properties, Capacities & Weights TECHNI CA L DA TA SHEET Kwi kst age Shor i ng Document Ref: TDSKSS Page No. 5 of 21 THE I NFORMATI ON ON THI S DATA SHEET REMAI NS THE PROPERTY OF MABEY HI RE LTD.

The primary beam, passing through the U Head should be centralised in the U head using timber wedges or similar. If no wedges are to be used then the U Head should be turned so that opposite flanges of the U head are touching the sides of the primary beam. This ensures that the primary beam is central in the U Head. Otherwise the capacity of the Adjustable U Head will then be limited by eccentric loading.

In sloping conditions, the average jack extension in a run of legs may be taken to establish, from the graphs, whether there is a need to provide restraint. The maximum leg load on any leg in the run must be used for this purpose, and bracing provided to resist the total horizontal force. This is because the introduction of braces into the scaffolding creates stiff zones, which will attract load in preference to the jacks, which need theoretically to move slightly before they mobilize their resistance to horizontal load. 2.3.3.1 Graphs for Bay Size 0.9m x 1.5m 2.0 Section Properties, Capacities & Weights Adjustable Base Jack 0.9 x 1.5 Graph 1 0.0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 5.5 6.0 10 15 20 25 30 35 40 45 50 55 Axial Load kN H o r i z o n t a l L o a d k N 200 300 400 500 600 Shoring U‐Head 0.9 x 1.5 Graph 2 0.0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 5.5 6.0 10 15 20 25 30 35 40 45 50 55 Axial Load kN H o r i z o n t a l L o a d k N 200 300 400 500 600 Shoring Sloping Head 0.9 x 1.5 Graph 2A 0.0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 5.5 6.0 10 15 20 25 30 35 40 45 50 55 Axial Load kN 200 300 400 500 600 H o r i z o n t a l L o a d TECHNI CA L DA TA SHEET Kwi kst age Shor i ng Document Ref: TDSKSS Page No. 11 of 21 THE I NFORMATI ON ON THI S DATA SHEET REMAI NS THE PROPERTY OF MABEY HI RE LTD.

The allowable load in such a situation is dependant upon the jack extension, the type of U head being used and whether or not the jack is braced. The stem of the jack is always situated above the Shoring Ties fixed in the second cluster of “V” pressings and consequently the strength of the length of the standard above the Shoring Tie level determines the load capacity of the system. Graph 11 shows the relationship between the jack extension and the allowable axial load for the Shoring U Head, when in conjunction with a Adjustable Stem in a braced condition. If the head is not braced, the allowable loads reduce dramatically as would be expected, but the values are still sufficient for use in lightly loaded areas of the Shoring system, such as access ways at the edge of Falsework for a bridge structure.

If possible, select a leg configuration which keeps the runouts less than 300mm at the U Heads and less than 425mm at the Bases, and then determine the safe leg loads taking into account any eccentricity of loading and runout. The next best option is to extend the bases and introduce bracing at the bottom where it is easier to fit. In cases where the slope of the soffit exceeds 1:15, please consult Mabey Hire Ltd. for advice. All of the examples shown below may require additional bracing depending on the horizontal loading requirements. Level Soffit Formwork Example where leg loads are such that no bracing is required Example where bracing is required: Primaries lace ‘U’ Heads in one direction Shoring J ack Brace lace ‘U’ Heads in other direction. Shoring J ack Brace as Diagonals required in both directions typically every 6 th U-Head. Sloping Primaries (Slope Less Than 1:15) Example where leg loads are such that no bracing is required Example where bracing is required: Primaries lace ‘U’ Heads in one direction Tube Runners lace ‘U’ Heads in other direction Diagonals required in both directions typically every 6 th U-Head. 4.0 Bracing of Adjustable U Heads Adjustable U-Head Level Soffit Primary 300mm or less maximum runout Interface between primaries and ‘U’ heads must have adequate resistance against sliding - either frictional or mechanical Runout Over 300mm Shoring J ack Brace lacing U-Heads together Shoring U-Head 300mm or less maximum runout Primary Soffit on slope Spike to U-Head Shoring U-Head Shoring J ack Brace lacing U-Heads together Runout Over 300mm Wedges to extend both sides of ‘U’ Heads to avoid eccentric loading TECHNI CA L DA TA SHEET Kwi kst age Shor i ng Document Ref: TDSKSS Page No. 18 of 21 THE I NFORMATI ON ON THI S DATA SHEET REMAI NS THE PROPERTY OF MABEY HI RE LTD.

These may be bedded and haunched with lean mix concrete to further spread the load, prevent accidental movement and eliminate foundation washout during inclement weather. If the ground is sloping the foundation will need to accommodate the resultant horizontal forces. 6.0.2 Setting Out Set out the shoring grid lines. The setting out, for the Falsework, would normally be provided by the Main Contractor. 6.0.3 Erecting the Kwikstage Before commencing work, users should ensure that they have: A working drawing – properly prepared by a suitable qualified & experienced person Prepared a method statement and carried out a risk assessment for the work Suitably qualified & experienced personnel to carry out the work Inspected the equipment before use and rejected any damaged items Checked that the foundations are at the correct levels and have suitable strength for the imposed loadings Checked that there is sufficient striking height in the make up Provided access equipment Provided an adequate supply of good quality timber wedges, packing, etc. Stage 1 – Build a Single 4 Leg Braced Bay 1a) Erect the First Leg 1b) Add the Second Leg 1c) Add a Third Leg 1d) Complete the First Bay Set Adjustable base to the correct runout.

Safe access must be installed for the next lift(s). Note that the SWL on a Shoring Tie acting as a board support is 150kg. Add the next lift of Standards, bracing them as they are installed. Add the final vertical lift, which consists of open-ended uprights to receive the adjustable ‘U’ Heads. Fit the ‘U’ heads and adjust to the required runout. Install the formwork in the ‘U’ Heads and adjust and level. If the scheme requires, fit Shoring J ack Braces to the Shoring ‘U’ heads. 6.0.4 Dismantling the Kwikstage The Kwikstage Shoring system can be dismantled by reversing the procedures outlined on these pages. Dismantled components should NOT be dropped from a height as this may damage the equipment. 6.0 Erection of Kwikstage Shoring If the scheme requires, fit Shoring J ack Braces to Adjustable Bases using a Shoring Adapter.
