1.Scaffolding boards and ramp boards should be fully laid on the crossbar. on both sides of the ramp, at the corners of the ramp and outside the scaffolding working surface, there should be 1m high railing and 18cm high guard plate in its lower part.
2.The surface of the steel tube should be straight and smooth, without cracks, scars, delamination, dislocation, hard bends, burrs, indentations, deep scratches, etc., and those that are severely rusted, bent, flattened, damaged or cracked must not be used.
3.The scaffolding boards must be fixed to the crossbeams of the metal tube scaffolding.
4.The formwork support should formulate a special construction plan according to the different heights, spans, loads, and processes of the engineering structure.
5.The supporting parts of the vertical formwork and the supporting columns should be installed on the foundation, should be added mats, mats should be sufficient strength and supporting area, and should be the center of the bearing.
6.Scaffolding is a working platform set up to ensure the smooth progress of the construction process, as a construction project in a few flat indispensable content, its erection is crucial to the whole project.
Erection sequence of scaffolding
Starting from the corner of the building, erect the columns one by one → place the longitudinal sweeping bar (close to the large crossbar of the picket beam), and then fasten it with the uprights → install the transverse sweeping bar (close to the small crossbar of the picket beam), and fasten it with the uprights → install the first step of the large crossbar (pay attention to fastening it with the uprights) → install the first step of the small crossbar (fasten it with the large crossbar) → install the connecting wall piece (or the temporary throw brace) → install the install the second big horizontal bar → install the second small horizontal bar → the third and fourth big horizontal bar and small horizontal bar → add the wall rod at the corresponding position → connect the vertical bars (length 6m) → add scissor braces and transverse diagonal braces → build the waist handrail bar and the footboard → pave the bottom scaffolding board → hanging safety nets (including flat nets and vertical nets).
