Accidents caused by scaffolding system collapses occur frequently at construction sites every year. This is largely unrelated to the size of the project or the strength of the construction developer. Do you know the specifications for spiral scaffolding? Spiral scaffolding specifications are crucial during construction. Proper erection and construction procedures can reduce or prevent the likelihood of collapse-related injuries and fatalities.
The product standards for spiral scaffolding are as follows:
- Spiral scaffolding models are primarily classified into two types, Type A and Type B, according to the “Safety Technical Specifications for Spiral Scaffolding Steel Pipe Supports for Building Construction.”
- Type A: The upright has a 60mm diameter and is primarily used for heavy-duty supports, such as those used in bridge construction. The accompanying disc weighs 0.55kg and is equipped with a 38mm lead screw.
- Type B: The upright has a 48mm diameter and is primarily used in building construction, decoration, stage lighting, and other fields. The accompanying disc weighs 0.46kg and is equipped with a 48mm lead screw. – Scaffolding poles: Standard dimensions, Q345B material, enhanced load-bearing capacity. Common pole sizes range from 500mm to 3000mm, with a 500mm modulus. Crossbars are 48mm in diameter, 2.5mm in wall thickness, and made of Q235B material. Common sizes range from 600mm to 2400mm, with a 300mm modulus.
What are the construction specifications for scaffolding poles?
Specifications for scaffolding poles include the following key details that must be considered during construction:
1. The formwork support should not be erected at a height exceeding 24m. If the height exceeds 24m, a special design must be used.
2. Specifications for adjustable bases: The exposed length of the adjustable base screw should not exceed 300mm, and the lowest horizontal bar, which serves as a sweeping rod, should not be more than 550mm above the ground. 3. Adjustable Brackets: The cantilever length extending from the top horizontal bar or double-slot steel joist must not exceed 650mm, and the exposed length of the screw must not exceed 400mm. The adjustable bracket must be inserted into the vertical bar or double-slot steel joist for at least 150mm.
Construction safety is crucial. To ensure the smooth and safe progress of the project, it is essential to understand the scaffolding operating procedures. Any problems must be addressed promptly to avoid accidents.
