The outer diameter and wall thickness of the wheel buckle scaffolding of Hengshui Hualiang Construction Equipment Factory are selected. Certification. Before the construction of wheel-buckle scaffolding, the incoming steel pipes must be sampled and sent to a testing unit with relevant national qualifications to conduct mechanical tests such as bending and tensile strength of the steel pipes. Only after the test results meet the design requirements can they be used in construction.
When building wheel-buckle scaffolding, the use of scaffolding boards and scaffolding sheets must comply with relevant requirements. Before erecting wheel-buckle scaffolding, maintenance should be carried out, rust should be removed and painted uniformly, and the color should be aesthetically pleasing to the environment. The scaffolding poles, protective railings and kicking poles are all painted yellow, and the shear braces are all painted orange. The bottom row of vertical sweeping poles are painted red and white. The connecting wall parts are made of steel pipes, and their materials should comply with the requirements for steel in the current national standard "Carbon Steel Structure". The diameter of the embedded bolts is section steel. The horizontal cantilever rods are made of channel steel, and the diagonal rods are made of struts and angle steel pipes.
The safety net adopts a dense mesh safety net. The mesh should meet the mesh/, and the penetration resistance test will not penetrate. The weight of a single net should be above the above. The color should meet the environmental effect requirements, and green is selected. If flame retardant is required, the safety net used must have a product production license and quality certificate, as well as a license issued by the Wenzhou City Construction Safety Supervision and Administration Department.
Malleable casting fasteners should be used for the erection of wheel fastener scaffolding, which should comply with the requirements of the Ministry of Construction's "Standards for Steel Pipe Scaffold Fasteners" and should be provided by
manufacturers with fastener production licenses. There must be no cracks, pores, shrinkage, and blisters. For forging defects, the specifications of the fasteners should match the steel pipe, the bonding surface should be clean, the movable parts should be flexible, and the minimum distance between the openings when clamping the steel pipe should not be less than 1. The steel pipe bolts must be tightened to a torque that will not cause damage. If old fasteners are used, the fasteners must be sampled and sent to a testing unit with relevant national qualifications to conduct tests on the fastener's anti-sliding force. The test results can only be used in construction if they meet the design requirements.
