It should also be fitted with steadying wires beneath the net to resist wind uplift. Stair towers are more rigid because scaftolding the built-in bracing resulting from the sloping stringers for the steps, which may be taken to act as the bracing of the tower at one side. The bracing on boarded lifts should be from under the outside ledger of a boarded lift down to the inside ledger of the lift below so as to avoid the toeboard.

The suspension may be by tubular members or by lifting gear and wire ropes which are not provided with the means of raising or lowering when in use.

The scaffoolding thickness of corrugated steel sheeting should be chosen after consideration of the durability required. Persons directly responsible for, and working on or employing persons to work on scaffolds should familiarize themselves with the contents of the relevant documents listed in appendix A and clause 5.

A thickness of 26 gauge is recommended only for short term requirements, when the sheeting is not to be re-used. The net scaffoldinf be attached to the framework with a winding of rope round the edge cord of the net or by the use of suitable clips. The forces at these points should be determined by the principle of leverage on the assumption that the applied weight from the scaffold acts between the inside and outside standards of the scaffold at a point 1 — of the width of the scaffold from the outside.

The longitudinal bracing should include the lower lift being started from the base of one of the outside standards.

Intermediate parts of the structure served, such as columns, may also be useful in providing stability. Scaffold boards should be cleaned on return from a construction site prior to stacking.

The tube welded to the drilled end plate can be standard scaffold tube, or tube of Lip ties may also be used over sills and under lintels. A scaffoldong arrangement may be used to form a through tie. Movement of the lower end should be prevented by a foot tie to the main scaffold or other suitable means.

The ledgers and transoms should be fixed to the standards with right angle couplers at lift heights which are determined by the load-carrying capacity of the standards.

It is heavy and exerts considerable forces on the access scaffold which should be well tied in at the fan level and stiffened from the building at the sfaffolding of the rakers. General 1 Scope This code of practice gives recommendations and includes some guidance for the design, construction and use of common scaffolds in steel, normally used in construction, maintenance, repair, hs demolition work, excepting those for the support of permanent work, commonly referred to as temporary works or falsework, and suspended scaffolds.

Persons directly responsible for, and working on or employing persons to work on scaffolds should familiarize themselves with the contents of the relevant documents listed in appendix A and sccaffolding 5. If access is possible on to a partly dismantled scaffold, warning notices should be fixed.

The necessary number of safety couplers should be added to the base frame of the structure and the tensions in the uprights catered for by sleeve couplers and lapping, where necessary. If it is required that there be means of raising or lowering a suspended scaffold, reference should be made to BS For reveal ties see 9. Anchorages and allied components should have a safe working capacity of 6.

Standard scaffolding materials and prefabricated frames may be used for the walls and scaffold tube trusses or prefabricated trusses or beams for the roof. Where there is a likelihood of persons below being struck by falling materials, these gaps should be covered with hardboard or similar sheeting. At the lower end it is preferable to butt the decking into a concrete starter ramp. Ties should be attached to both the inside and outside ledgers or standards at a 5937 not more than mm from a ledger braced standard, and as near to a node point as possible.

For further information reference should be made to BS The guardrail posts should be fixed to the transom with right angle couplers so as to avoid the outward rotation of the posts which might scaffoldng if they were fixed to the ledgers. In any case of doubt, destroy the board. Driven tube anchors should not be used on a down slope towards the structure.

Supplementary fittings may be required. Timber members should be in good condition and of scaffoldiing quality suitable for withstanding the stresses calculated from the applied loads.

In confined areas it may be necessary to provide an adequately protected thoroughfare while the scaffold is in use. This will be indicated in the amendment table on the inside front cover. The guy should be attached see Figure 19b at the bottom of the front tube and prevented from slipping up by a scaffold fitting. Notices giving maximum permitted vehicle weights and the number of vehicles allowed at any one time should be fixed at each end of elevated roadways and vehicle ramps.

The lift heights should in general be 2 m except where locally concentrated loads are being specially catered for see also Such tubes should also be fixed during dismantling if low level ties are impracticable.

Section 2 makes recommendations on the care of the materials and on the degree of wear and tear which should not be exceeded if the materials are to be included in a scaffolsing which is intended to be in accordance with this code.

This edition introduces technical changes but it does not reflect a full review or revision of the standard which will be undertaken in due course to make the standard compatible with the forthcoming European Standard for scaffolds, bss to be published in by the European Committee for Standardization CEN. Figure 27 shows typical constructional details. Where this hinders access along a platform, attachment to the inside ledger or upright only is permissible.
