With the vigorous development of the steel structure industry. Details in the construction process of steel structures are often overlooked. Sichuan Xirong Steel Structure Construction has been engaged in the steel structure industry for 17 years and has accumulated a lot of construction experience in the construction process of Sichuan steel structure. Now I would like to introduce to you some construction details that should be paid attention to in the process of steel structure construction in Chengdu.

1. During the construction of the

steel structure, the arrangement of the bolt position of the flower basket on the horizontal support should be reasonable, not too far from the main beam, and should consider the convenience of installation. Otherwise, workers must lean out to tighten the basket bolts or use a ladder to go up during installation, or climb the purlins to tighten the basket bolts after the installation of the steel structure purlins, which is very unsafe. In addition, consider the placement of the brace, and do not fight with the brace when arranging the horizontal brace.

2. The corner plates of doors and windows of Sichuan steel structure engineering cannot be generalized, because it is not guaranteed that the plates are located in the peak or trough of the profiled plate in the steel structure construction.

3. The connection between the wind-resistant column of the steel

structure engineering and the steel beam is connected by spring plate as much as possible, because the lower deflection of the beam of the middle span is relatively large after installation, and the beam of the gable wall will cause the roof to be uneven if it is connected with the wind-resistant column with bolts.

4. When the beam and column are made of the tie rod connection plate, the hole is not properly extended, and in some places, because the connecting plate on the tie rod is too long, the space is too small, and the tie rod is too long to put in. This is often the case with some secondary beam structures.

5. Pay attention to clamping the sealing plate at both ends of the beam and column with a fixture, otherwise it is easy to deform during the welding process, and there will be a gap between the sealing plate and the sealing plate during installation, and it cannot be pulled back with high-strength bolts.

The above is the introduction of the precautions required for the construction process of Sichuan steel structure sorted out by Xirong steel structure construction, hoping to help you in steel structure construction.
