Fasteners - Steel pipe fasteners are often used on construction sites, and the appearance quality of the fasteners is often inspected. If there are cracks, deformations, or bolts showing slippery threads, the use of these unqualified steel pipe fasteners is prohibited to prevent construction defects and accidents.
Classification of fasteners - steel pipe fasteners on construction sites:
1. Cross shaped steel pipe fasteners are applied to a multi story and multi span spatial frame structure system composed of longitudinal and transverse horizontal bars and vertical bars. Due to the fact that the connection between the poles is a fastener steel pipe fastener connection, it is impossible to completely converge at one point, with the characteristic of "semi rigid", which also has many uncertain factors. Therefore, in the process of installation, in addition to using cantilever sections for the external frame, great attention is paid to the production method of scaffold spacing and cross shaped fasteners, including the hot pressing process of the cover plate and the middle part.
2. The main advantage of rotating steel pipe fasteners is their high hardness, strength, and toughness. After surface quenching, the surface of the fastener - steel pipe fastener has significant compressive internal stress, high fatigue fracture resistance, no need for overall heating, small deformation, low electrical energy consumption, pollution-free, fast heating speed, and light surface oxidation decarburization. Heating equipment can be installed on mechanical processing production lines, making it easy to achieve mechanization and automation, facilitate management, reduce transportation, save manpower, and improve production efficiency.
3. The use techniques of right angle steel pipe fasteners. In addition to using lap joints at the top, all other joints must be connected using docking fasteners - steel pipe fasteners. The appearance quality requirements of such fasteners - steel pipe fasteners are strict, and there should be no cracks, parallel or slippery threads.
