Performance characteristics of right-angle fastener
The cumulative sand sticking area of fasteners should not be greater than 100 mm2. No scale is allowed on the surface of fasteners. Other technical requirements meet the requirements of GB 1583 1-2006. Strong deformation resistance. Compared with the common steel plate stamping fastener, due to the different manufacturing processes, it breaks through the limitation of the traditional stamping process on the material thickness (the stamping process can only reach the thickness limit of 3.5 mm, and it is not easy to deform due to the strength in actual use), reaching 5 mm, which can completely ensure that it will not deform during use, thus ensuring the safety and repeated effective use of the product. Right-angle fasteners can ensure the good performance and use of fasteners in use and ensure the normal use in construction. Strong anti-skid performance. The slip resistance of the fastener ensures that the steel pipe and the fastener are in the joint surface state with large joint area, overcomes the defect of point or line joint between the cast iron fastener and the steel pipe, and eliminates the hidden danger of steel pipe slip.
Fasteners have the advantages of safety, quality and brand. Renting fasteners is easy and labor-saving, and the rental income exceeds renting inferior iron fasteners. Convenient maintenance. Because the product itself is not easy to rust and damage, it is very convenient to maintain after use, which not only reduces the maintenance difficulty but also saves the maintenance cost. Strong corrosion resistance. The whole piece is passivated and galvanized to prevent corrosion, which greatly improves the corrosion resistance and has a long service life, far exceeding the service life of cast iron fasteners. Strong anti-detachment ability. The new connection and new nut ensure that the fastener can always be fixed vertically and firmly when the steel pipe is deformed, and put an end to the possibility of steel pipe slipping.
Production requirements of right-angle fasteners
Right-angle fasteners must conform to the drawings approved according to the prescribed procedures for production. The material of fasteners shall conform to the mechanical properties specified by KTH330-08 in GB9440. Fastener production must be carried out in accordance with the proportion of ingredients specified in the process. The heat treatment of fasteners should strictly implement the temperature and time of each stage specified in the process. Fasteners are processed in strict accordance with the process, and the joint surface between fasteners and steel pipes is pressure tested and shaped to ensure the anti-slip and tensile performance requirements of fasteners. Fasteners (except the base) must pass the torque and pressure test of 70N.m and are not allowed to be damaged. When P= 14KN, the sliding resistance of the right-angle fastener is △ 2 ≤ 0.5mm ..
Tensile properties of butt fasteners, when P=6KN, △ 2 ≤ 0.2mm ... No more than one sand hole with sand hole area greater than10mm2 is allowed, and the cumulative area shall not be greater than 40mm2.
After a brief introduction of the above contents, everyone should have a more detailed understanding of right-angle fasteners. Because the right-angle fastener should have certain bearing capacity and deformation resistance during use, it should be fixed firmly as far as possible during use to prevent the bracket from loosening and slipping. At the same time, consider its material. Different materials should have different strengths, so materials with higher hardness are generally selected as right-angle fasteners. There are many right-angle fasteners on the market now, but the general right-angle fasteners have very strict production standards. Therefore, the right-angle fastener should be understood in detail before use, and then used. I hope the above contents are helpful to everyone.
