Analysis of common problems in the processing of steel structure housing projects!

Some common problems in the construction of steel structure housing projects are as follows: 1. The position of the flower basket bolts on the horizontal support of the steel structure housing project should be reasonable, and should not deviate too much from the main beam, and should consider the convenience of installation. Otherwise, workers need to lean out to tighten the turnbuckle bolts or use a ladder to go up during installation, or climb up to the purlin to tighten the turnbuckle bolts after the purlin installation is complete, which is very dangerous. At the same time, the arrangement position of the corner braces should also be considered, and do not fight with the corner braces when arranging the horizontal braces. 2. For steel structure housing projects, do not unilaterally consider factors such as 'pulled edge and compressed edge' on the purlin's bracing holes, and punch out holes with different upper and lower margins, because it is easy to install backwards during installation, and the result is the opposite. unfavorable. 3. Corner boards such as doors and windows cannot be generalized, because there is no guarantee that the board is located at the crest or trough of the profiled plate during construction. 4. When doing large-scale steel structure housing projects, the numbering of the detailing drawings must take into account the convenience of production, delivery and installation. 5. It is necessary to understand the true meaning of the 'data such as load' provided by Party A, because Party A often does not understand it very well, and as a construction party, it should be empathic. After the preliminary work is done, the follow-up work can be carried out. . 6. The quality of the welding seam of the steel structure housing project is not up to standard; this process is a hidden project and one of the most prone to quality problems 7. Improper operation of the previous process and technical problems of the operators: are the main problems that directly affect the quality of the project , so this type of problem must be detected and judged by a professional testing company using professional testing tools. Generally, it is divided into slag inclusion, unmelted, porosity, etc. according to the type of defects in the weld. 8. Painting process: It is a hidden process, and its impact on the steel structure house is less than the impact on the building function. The quality problems of the process are mainly manifested in: the paint film on the surface of the component falls off in large areas and locally, the paint film on the surface of the component falls off and sags, the thickness of the paint film is not enough, the thickness of the paint film is unevenly distributed, and the color of the paint film is different. larger.
