Arrangement and requirements for steel structural bolts

Arrangement and requirements for steel structural bolts

Steel structures are connected by bolts, welding, and riveting, among which bolt connection is one of the common connection methods. The connection of steel structures is an important factor related to the stability of steel structures. Therefore, special attention must be paid to the layout and construction requirements when connecting steel structural bolts to the structure.

Therefore, in engineering construction, it is necessary to clearly and accurately determine which layout method is more suitable during the construction process. Regardless of the arrangement, the spacing, end distance, and edge distance of the bolts on the component should also meet the following requirements:

1. The stress requirement is that the spacing between bolts should not be too small, otherwise it will weaken the cross-section of the component too much. When the Chengdu steel structure components are under pressure, the middle distance of the pressure direction should not be too large, otherwise it is easy to generate bulges in the connecting plate. In order to prevent the steel plate at the end of the component from being cut, the outermost row of bolts in the direction of internal force should have sufficient end distance.

2. The construction requires that the distance between the bolts should not be too large, otherwise the steel plates cannot fit tightly. The middle distance, edge distance, and end distance of the outer row bolts should not be too large, otherwise the contact surface is not tight enough, and water intrusion can cause corrosion.

3. Construction requires that there should be sufficient distance between bolts to tighten the nuts with a wrench.

The connection method for steel structure houses may seem simple, but its practical application is very important. Every detail in the process of steel Structural engineering can ensure the quality and stability of steel structures. The so-called details determine success or failure. Only details can complete this work. Qualified steel structure.

The arrangement of bolts on components should be simple and uniform, generally using two forms: parallel and staggered. The juxtaposition is relatively simple and neat, and the size of the connecting plate used is small. However, due to the presence of bolt holes, the cross-section of the component is greatly weakened. Bias can reduce cross-sectional weakening, but the layout is more complex and the connecting plate size is larger.
