Standard scaffolds 8 Description of access scaffolding 8. When propping is used to secure the acaffolding end of the cantilever beam, every prop or tube so used should be effectively maintained in position by an assembly of tube and fittings and be itself of adequate strength to carry the loads imposed on it.
Plan bracing should be fixed if required. Alternatively, it may be necessary to embed the whole of the lowest level of lacing tubes in order to provide adequate stability.
Where the design depends on special materials, the designer should ensure that this information is adequately conveyed to stockholders and to the erectors, e. They should be fixed together with tubes and fittings connected with right angle fittings in preference to lashings.

All vehicle ramps and elevated roadways should be the subject of design and calculations. However, it should be realized that the anchorage value of scaffllding elements is frequently negligible. The lower end of all diagonal bracing should be attached to the foot of a standard by a swivel scaffoldin or to a foot tie with a right angle coupler. The suspension points may be the outriggers from the roof rig of a suspended platform, additionally counter-weighted, or may be screw-in or anchor tie points at a lower level.

In all cases, the bracing tubes should be connected either: The horizontal tube holding the gin wheel should be fixed with right angle couplers to two uprights in the case of an independent tied scaffold.
When in use in exposed situations, the tower should be tied to the building it is serving. This arrangement may require an extra width on the scaffold to accommodate the brace. The distance between the lines of uprights should be the minimum necessary to accommodate the required number of boards and toeboards. It should be adequately stabilized. It is not scaffoldjng that they should spread the load over the surface of the reveal but that they should grip it and protect it at the same time.
The vertical forces on the building should be taken at the location of the vertical tubes on the pads. Scaffolds which are to remain in use while partly dismantled should be fitted with end guardrails and toeboards at the end of the portion in use.
This code of practice represents a standard of good practice. To be effective, a ledger should be fixed adjacent scaffolxing where the knee brace meets the standard. The forces in the bracing, particularly in the lower lifts, may be in excess of the safe working load of the right angle couplers, in which case supplementary couplers or shear pins should scaffoldibg used at each end of the braces.

Scaffolds – Vs requirements and general design.
Transoms to the working lifts in the side bays may be fixed to the ledgers to provide level supports for the decking. The principal forms are: Toeboards may be incorporated within the screen and the screens should be capable of preventing the materials being used passing through.
The absence of the braced upper lifts requires that the lateral stability of the deck is derived from one lift of bracing only, which should therefore be correctly positioned and fixed.

The stiles should be securely fixed svaffolding the scaffold at the top by lashings, as shown in Figure scaffoldlng, or by other attachments. They should ensure that the scaffolds are maintained in the relevant condition throughout their use. If they are on finished concrete or any scaffoldingg of flooring, base plates should be used. The method normally used is to select the required length of the access scaffold to which the loading bay is to be attached and to reduce the spacing of the standards in this length to supplement their total load-carrying capacity to the required amount.
Spanners and podgers should have lengths as recommended by the coupler manufacturer. Longitudinal bracing should be inserted in the long walls and transverse bracing in the end walls or end gable. In this case, the scaffold should be stabilized by rakers and, if necessary, foot ties to them, until ties can be inserted in the wall.
