Due to its own advantages, steel structures have been widely used in modern buildings such as factories, bridges, industrial plants, and high-rise buildings. In the process of a large number of engineering constructions, steel structure factories have also exposed many common quality problems. Some opinions have been put forward regarding the common problems and rectification measures in the acceptance and completion acceptance of steel structures in recent years.
1. If there is a gutter, the tie bars cannot be designed close to the top of the column, otherwise it may not be possible to install the downpipe. In addition, it is necessary to consider the position of the gutter downspout, tie bars, and column supports, otherwise tie bars or column supports may be encountered.
2. The arrangement of flower basket bolts on the horizontal support should be reasonable, not too far away from the main beam, and should be easy to install. Otherwise, during steel structure construction, workers must lean out and tighten the suspension basket bolts or use a ladder to climb up, or climb up the purlins and tighten the suspension basket bolts after installation, which is very unsafe. In addition, the placement of the angle braces should also be considered, and when arranging the cross braces, do not fight with the angle braces.
3. Do not unilaterally consider factors such as “pulling edges” and “pressing edges” on the purlin holes, which may result in uneven top and bottom margins of the holes, as it is easy to reverse the installation of purlins and the effect is not good.
4. The door and window corner panels cannot be generalized, because in steel structure construction, it cannot be guaranteed that the panels are located in the peaks or valleys of the profiled steel plate.
5. When numbering detailed drawings in large-scale steel structure factories, consideration must be given to the convenience of production, delivery, and installation.
6. We must understand the true meaning of the “load data” provided by Party A, as Party A often does not understand these professional concepts. We need to put ourselves in others’ shoes. If the preliminary work is done well, the subsequent work will be much better.
