Specification and type of scaffold erection
2 fasteners should be qualified factory, where brittle crack, deformation, sliding wire shall not be used. 3 steel scaffolding should be 2 ~ 3mm thick No. 3 steel plate, with the length of 1.4 ~ 3.6m, 23 ~ 25cm, width of rib height should be 5cm, available on both ends of connecting device, surface with anti slip hole, where the crack distortion may not be used.
technical requirementThe materials used for steel pipe scaffold shall meet the following requirements:1 steel pipe diameter should be 48 ~ 51mm, wall thickness of ~ 3.5mm, length of 2.1 ~ 2.8m and 4 ~ 6.5m is appropriate, there are serious corrosion, bending, cracks, damage shall not be used.
Specification for scaffold erection(a) basic requirements1 important scaffolding must develop a construction plan, if necessary, to develop safety assurance measures. 2 more than 25m high scaffolding must adopt the fastener type steel tube scaffold, the single pole scaffolding height should be controlled within 50m; height of more than 50m of the scaffolding should be effective measures by a double pole, wire rope, cable stayed unloading segment, and additional design.3 the design of the scaffold shall meet the requirements of the project and shall indicate its use, maximum static load, maximum dynamic load andThe selected design parameters and structural parts shall not be lower than the existing national and industry related safety technical standards.4 scaffolding in the construction of the need to change the original structure, Gago (wide), to its use, etc., must be verified by the technical department, and the approval.
4 the vertical pole of the scaffold, the size of the cross bar according to the specific use of the scaffold to determine the specific circumstances, but shall not exceed the following values:Horizontal vertical rod vertical rod large cross bar small crossbar small cantilever cantilever length 1.5m 1.2m 2.0m 1.5m 0.45M5 ramps board, springboard slope is no larger than 1:3, width of not less than 1.5m. 6 wooden rods: wire with 8#
