We often hear about scaffolding erection, but are there standards for it? What defines a standard scaffolding erection? Today, let’s take a look at the standards for scaffolding erection.
Scaffolding Erection Standards:
1. Scaffolding steel pipes should preferably be φ48.3×3.6 steel pipes. Drilling holes in scaffolding pipes is strictly prohibited; pipes with cracks, deformation, or stripped bolts are strictly prohibited. Couplers must not fail when the bolt tightening torque reaches 65 N·m. Product certificates should be available, and sampling retesting should be conducted.
2. Scaffolding includes ground-supported scaffolding, cantilevered scaffolding, attached scaffolding, and frame scaffolding. A mixture of steel and wood, or steel and bamboo, is strictly prohibited, as are scaffolding structures with different load-bearing properties connected.
3. Safety netting on scaffolding must be tightly installed, ensuring a flat, taut, and straight surface. Horizontal overlaps must ensure that at least one hole is overlapped, and all holes must be fully secured without any gaps. There should be no noticeable gaps when viewed from a distance.
4. The binding of the top and bottom edges of the scaffolding must not obscure the main horizontal members. All bindings should be uniformly fastened to the inside of the main horizontal members. The bindings between steps must be tight, and no bindings should be missed.
5. The load on the scaffolding must not exceed 270 kg/m². It can only be used after passing inspection and being tagged. Regular inspection and maintenance are necessary during use. Scaffolding with a load exceeding 270 kg/m² or with special design features should be redesigned.
6. Steel pipe uprights of the scaffolding should be equipped with metal bases. For soft foundations, wooden planks or ground bracing should be used.
7. Scaffolding uprights must be vertical, with a vertical deviation not exceeding 1/200 of their height. The spacing between uprights should not exceed 2 meters.
8. Sharp bracing and supports should be installed at both ends of the scaffolding, corners, and every 6-7 uprights. If supports cannot be installed at heights exceeding 7 meters, they must be securely connected to the building every 4 meters vertically and every 7 meters horizontally.
9. 1.05-meter guardrails should be installed on the outer side of the scaffolding, along ramps, and platforms. When laying bamboo or wooden planks, both ends must be securely tied; unsecured use is strictly prohibited.
10. Scaffolding horizontal members should be heightened and reinforced at passageways and ladders to ensure they do not obstruct passage.
11. For cantilevered scaffolding, the horizontal member spacing is generally 1.2 meters, and diagonal bracing should be added. The angle between the diagonal bracing and the vertical plane should not exceed 30°.
