What should be paid attention to when build steel structure buildings?

Steel structure buildings are assembled from various components, so what problems should be paid attention to when building steel structure buildings? To ensure the quality and stability of steel structure buildings.

1. It is necessary to clarify the original structure layout, select a reasonable connection position and connection form between the steel structure and the original structure, and avoid the damage of the original structure by the load of the steel structure.

2. The primary and secondary steel beam layout of the steel structure should be combined with the construction, decoration and installation design of the attic to avoid or reduce the secondary damage to the steel structure during the decoration and installation process.

3. It is not recommended to use hollow steel such as square steel and pipe steel, because it is difficult to paint the inside of the steel with anti-rust paint, and the cold and hot changes in the north, the rust of the condensed water on the steel will pollute the ceiling and wall, and seriously endanger safety.

4. The force of the steel structure layout should be clear, and the force transmission route should be clear and concise. Due to the obvious force vibration of the steel structure itself, precise analysis and calculation are required to strictly control the structural deformation and vibration frequency. Ensure the visual beauty of the structure, eliminate the resonance between the structure and human activities, avoid the shear fatigue damage of the structure caused by the resonance phenomenon, and at the same time ensure the comfort during use.

5. For the purchase of steel (channel steel, I-beam), generally we have 10, 12, 14, 16 specifications to choose from. No matter what specification you choose, it is recommended to use “national standard” steel. Because its steel quality and specifications are superior to “non-standard steel”, non-standard steel has high hardness, brittle steel, poor ductility, and is not easy to cut and perforate.

6. Before fixing the channel steel, the side of the channel steel against the wall should be painted with anti-rust paint, but the other parts should be painted after welding, otherwise it will affect the welding work.

7. For the construction of steel structure, pay attention to that the I-beam and channel steel must have the same specifications, and must choose “full welding”. The main keel should be whole steel, and intermediate welding is strictly prohibited.

There are many objective factors in nature that affect the construction of steel structure buildings. Therefore, in the process of building a steel structure building, it is also necessary to select the type of steel structure and make corresponding protective treatments according to the geographical environment and climate. In the process of erection, installation and production of steel structure buildings, every link and every detail are linked together, so construction technicians should have enough patience to ensure the quality of each link, and finally return a safe and reliable building to the owner.
