The anti rust ability and anti deformation ability of fasteners
The anti slip performance of fasteners ensures the fit between seamless steel pipes and fasteners, with a large total dining area, thus eliminating the defect of point or line contact between pig iron fasteners and seamless steel pipes, eliminating the safety hazard of seamless steel pipe misalignment, and ensuring the actual effect of seamless steel pipe application. The anti slip characteristics of seamless steel pipe fasteners can eliminate the defects of pig iron fasteners and seamless steel pipes meeting at points or lines, and reasonably reduce errors and safety accidents on the construction site.
The anti rust ability of fasteners is strong. The entire passivation treatment and hot-dip galvanizing bi-directional anti rust solution further improve its anti rust ability, with a long service life far exceeding that of pig iron fasteners.
The fastener has strong resistance to deformation. Compared with ordinary thick steel plate die fasteners, due to different processing techniques, it improves the traditional die design's limitation on material thickness (the die design thickness is only 3.5 mm, and the compressive strength during the entire use process is insufficient to deform to 5mm), and can completely guarantee no deformation during the entire use process, thereby ensuring the safety and reasonable repeated use of the product. This utility model can ensure excellent performance indicators and the main purpose of fasteners in application, ensuring normal use on construction sites.
The appearance quality of steel pipe fasteners should be tested. If cracks, deformations, or bolt slippage are found, they should not be used to avoid using these construction aids.
Steel pipe fasteners must undergo sampling inspection before use to verify the quality of the steel pipes and fasteners. The sampling quantity should be carried out according to the corresponding rules, and sampling inspection should also be conducted in a certain proportion. Products that have not been inspected and qualified shall not be used.
For the bearing capacity of steel pipe fasteners, during the construction process, overloading is not allowed and a certain weight must be borne. Scaffolding cannot be connected to formwork supports, and certain treatment must be carried out during connection to ensure the reasonable bearing capacity of the fasteners.
