Steel structure bolts are commonly used as a connector and are widely used in steel structure engineering. It is mainly used to connect the connection points of steel structure plates, and can achieve better fastening performance. Steel structure bolts have high strength and belong to one of the standard parts. Different types of steel structure bolts have different classification and construction methods, below we will explain in detail for your reference.
The steel structure bolt is a kind of high-strength bolt, which is widely used in steel structure engineering. In the steel structure, the fastening function of the steel structure bolt is very important, so its performance requirements are relatively high. In general, the steel structure needs to use 8.8 and above high strength bolts, as well as 10.9 and 12.9 steel structure bolts. For some steel structure bolts that do not require electroplating, you can choose natural color materials when purchasing. When laymen use steel structure bolts, they must understand the relevant knowledge in advance. Only in this way can we avoid choosing the wrong product. Therefore, it is particularly important to understand the classification and construction methods of steel structure bolts. Steel structure bolts are mainly divided into two types: torsional shear high-strength bolts and large hexagonal high-strength bolts. ① Large hexagonal high-strength bolts Large hexagonal high-strength bolts belong to the high strength level of ordinary screws. It uses a large hexagonal head design, with high fastening performance. ② Torsional shear high-strength bolts Torsional shear high-strength bolts are improved on the basis of large hexagonal high-strength bolts. Its appearance shape is "T" type, with better construction performance. In the construction process, the upper and lower sections of the torsional high-strength bolt can be directly locked with a torque device at the same time, and its structural design can reduce the situation of bolt breakage caused by the construction process.
Construction of steel structure bolts In the construction of steel structure bolts need to carry out the initial tightening and final tightening two steps. ① Initial tightening steel structure bolts need to use impact electric wrench or torque adjustable electric wrench. When installing bolts with an electric wrench, the torque should be controlled according to the standard, so as not to affect the use of bolts. ② Final tightening steel structure bolts have different construction requirements in the final tightening link. - For the torsion shear steel structure bolts, the torsion shear electric wrench must be used for final tightening; - For torque type steel structure bolts, torque type electric wrench is required for final tightening. It should be noted that when the electric wrench is used for final tightening, the tightening torque of the bolt should be carefully mastered to avoid installation errors caused by too tight or too loose. In summary, steel structure bolts, as an important connector, are widely used in steel structure engineering. When purchasing and using steel structure bolts, it is necessary to have a sufficient understanding of their classification and construction methods. Only in this way can we effectively avoid some installation errors and problems in use.
