2.5 SUPPORTING STRUCTURE2.5.1 GENERALThe supporting structure shall be capable of supporting the most adversecombination of loads applied by the scaffold during the period of its service.2.5.2 STRENGTHENING OF SUPPORTING STRUCTUREWhere the supporting structure is not capable of supporting the most adversecombination of expected loads in Clause 2.5.1, it shall be strengthened bypropping or other means.2.5.3 SOLEPLATESWhere soleplates are required, they shall be designed to distribute the loadfrom a scaffold to the supporting structure.28 SAFE ERECTION AND USE OF SCAFFOLDING
3. STANDINGSCAFFOLDS3.1 SCOPEThis part covers standing scaffolds which are supported wholly or partly fromtheir base. The scaffolds may be either free-standing or held sideways by ties,rakers or other means.The kinds of scaffolds generally used are:(a)(b)(c)Timber scaffolding;Tube scaffolding in steel or aluminium; andScaffolding with proprietary equipment.3.2 FOUNDATIONSScaffolding foundations must be adequate to carry the whole weight of thescaffold, including the imposed loads, and must be maintained in a stablecondition during the life of the scaffold. Steel base plates must be used underall standards.When scaffolds are supported on the ground, suitable sole plates must be usedto spread the load. The sole plates should preferably be long enough tosupport at least two standards. (See fig. 4).Timber sole plates must be not less than 200 x 38 x 500 mm long. Bricks,blocks and similar loose material are unsuitable as they are liable to fall overor split, and are easily driven into the ground.Where the foundation is levelled concrete of adequate thickness or of a similarhard surface, the sole plate may be omitted, but steel base plates must beprovided at the bottom of all standards.Fig. 4 Support for tubular scaffold standards.SAFE ERECTION AND USE OF SCAFFOLDING 29
