How to install purlins in steel structure workshop?

At this stage, new industrial production projects have more and more requirements for steel structure plants. Steel structure plants are favored by a large number of people for their simple construction, short construction period, high utilization rate, recyclability and other advantages. The corresponding colored steel tile enclosure structure is also highly praised by many customers for its advantages of convenient installation, convenient disassembly, strong moisture-proof property, and good actual effect of thermal insulation. Here is a simple analysis of how to install purlins in steel structure workshop?

Purlin installation of steel structure workshop

1. When the steel frame of the steel structure workshop is lifted in place, the installation of purlins can be carried out. This project stipulates that one side of the purlin is welded with the steel frame by electric welding, and there are many electric welding on the spot for purlin installation.

2. The purlin installation staff of the steel structure workshop shall be on the fixed steel frame and pay attention to the safety of being listed on each center line.

3. The purlin is fixed with the beam by bolts. At this time, because the structure is still not aligned, the bolts used to connect the purlin, girt and eave support beam need not be tightened for later calibration.

4. When the purlins of the bay are installed, the installation of the next purlins shall be carried out. At this time, pay attention to that the installation orientation of the bolts is consistent with that of the bolts at the overlap of the purlin reinforcement of the previous span, and ensure that the overlap bolts of the purlin reinforcement on each centerline are consistent, which not only improves the appearance, but also ensures the firmness of the connection between the main structure and the secondary structure.

5. When installing bolts at the joints of all purlins and beams in the steel structure plant, the bolts shall be downward and all bolts need not be tightened.

6. After the installation of all purlins, the bolts of all secondary structures (purlins, diagonal braces, etc.) on the steel frame shall be further tightened after straightening and calibration to ensure a stable structure.

7. After column lifting and calibration, install tie rod support points between columns, and then carry out diagonal support installation between columns. Horizontal supports and purlins of flat roof shall be cross installed during the whole process of steel column installation of steel structure workshop.

8. Before the installation of the support points, the flatness of the steel column shall be rechecked. After the acceptance standard is met, the fixed support points shall be installed and fixed to make them rigid and reduce the total deviation in the whole process of the installation of the longitudinal prefabricated components of the prefabricated components.

9. After the installation of purlins, the installation of purlin push rod and main beam tie rod shall be carried out. The installation of push rod can use wood board, bamboo ladder, etc. as the secondary actual operation service platform to accelerate the installation rate. The push rod must be tightened to make the purlin flat.
