How to choose scaffolding
1、The steel pipe adopts 48mm×3.5mm welded steel pipe, the steel strength grade Q235-A, the steel pipe surface should be straight and smooth, there should be no cracks, delamination, indentation, scribe and hard bend, the new steel pipe must have a factory Certification. Before the construction of the scaffold, the steel samples must be sampled and sent to the testing unit of the relevant national qualifications to carry out mechanical tests such as bending resistance and tensile strength of the steel pipe. The test results can meet the design requirements before they can be used in construction.
2. The erection of scaffolding using malleable casting fasteners shall comply with the requirements of the “Standard for Fastening Steel Pipe Handles” (JGJ22-85) of the Ministry of Construction, and shall be provided by the manufacturer with the production license of fasteners without cracks, porosity, and shrinkage. Forged defects such as sand holes, the specifications of the fasteners should be matched with the steel pipe, the affixed surface should be dry, the active part should be flexible, and the minimum distance of the opening when clamping the steel pipe should not be less than 5mm. Tightening torque of steel pipe bolts reaches 70N. m must not be destroyed. If the old fasteners are used, the fasteners must be sampled and sent to the test unit of the relevant national qualification to carry out tests such as anti-sliding force of fasteners. The test results can meet the design requirements before they can be used in construction.
3, before erecting the shelf should be maintained, rust and uniform coloring, color and environmental beauty. Scaffold poles, protective railings, and kickboards are all painted yellow, and they are painted in orange. The bottom row of poles and sweeping poles are painted red and white.
So, do you know how to choose scaffolding or do you want to make scaffolding yourself ?
