Description

Steel structure joint fasteners

This creation relates to the field of joining steel structure parts, in particular, it refers to a steel structure joining fastener.

When the steel structure 90 (regardless of C-section steel, H-section steel, flat iron, square tube) is to be joined, the current methods are roughly as follows:

1. The advantages of combining the steel structure parts 90 by welding (whether it is spot welding or full-circle welding) are that the processing is more convenient, and the construction personnel can construct according to the construction site status, but the disadvantages are: (1) For extended steel structure parts In terms of the length of 90, the straightness and levelness of the steel structure 90 after welding should be considered; (2) the steel structure 90 after welding needs to consider the material change caused by thermal influence, or the problem of damage to the surface coating after welding.

2. As shown in Figure 1, in the case of C-shaped steel, when the steel structural member 90 has a load-bearing requirement, a lap joint method is usually used, that is, a connecting piece 91 is provided at the joint of the two steel structural members, and the bolts are connected. After the 92 penetrates into the connecting piece 91 and the steel structure member 90, the bolt 92 is fixed with a nut. However, the disadvantages are: (1) The connection method of using the bolt 92 and the nut to lock is easy to cause the steel structure member 90 to be locked. (2) The bolt 92 and the nut are locked by the connection method. Sometimes under the constant vibration, the bolt 92 and the nut may be loosened, and there are concerns about industrial safety.
