Steel structure bolts are also high-strength bolts, and they are also a kind of standard parts. The understanding of steel structure bolts mainly depends on the classification and construction of steel structure bolts. If you are a layman, if you need to use these accessories, you must know the relevant knowledge in advance, so that you will not choose the wrong product. Today, I will follow the editor to take a look at the comprehensive analysis of steel structure bolts for your reference.
1. Application of steel structure bolts
Steel structure bolts are mainly used in steel structure engineering to connect the connection points of steel structure steel plates. Steel structure bolts are a kind of high-strength bolts and also a kind of standard parts. The fastening performance is better, and it is used for steel structure and engineering to make the fastening function. In general steel structure, the required steel structure bolts are all grade 8.8 or above, and there are grades 10.9 and 12.9, all of which are high-strength steel structure bolts. Sometimes the bolts on steel structure do not need electroplating, and use natural colors. It's OK.
2, the classification of steel structure bolts
Steel structure bolts are divided into torsion shear type high-strength bolts and large hexagonal high-strength bolts. Large hexagonal high-strength bolts belong to the high-strength grade of ordinary screws, and torsion shear type high-strength bolts are improved types of large hexagonal high-strength bolts for better construction...
3. Steel structure bolt construction
The construction of steel structure bolts must be tightened first and then final tightened. The initial tightening of steel structure bolts requires an impact type electric wrench or torque adjustable electric wrench; and the final tightening of steel structure bolts has strict requirements, and the final tightening of torsion type steel structure bolts must Use torsion shear type electric wrenches, and torque type electric wrenches must be used for final tightening torque type steel structural bolts.
Summary: The relevant information about steel structure bolts is introduced here. I hope this article will be helpful to you. If you have anything you don’t understand, you can leave a message to the editor below, and we will answer you as soon as possible.
