The steel structure building construction technology is simple, has good stability and seismic resistance, has won the recognition of the masses. In the era of advocating green environmental protection building, whether in rural or urban areas, steel structure building seems to be an inevitable trend
The steel structure house is composed of various components. What should be paid attention to when building the steel structure house? To ensure the quality and stability of the steel structure house. Today, let's discuss some related knowledge about building the steel structure house
1. It is necessary to make clear the layout of the original structure, select a reasonable connection position and 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 layout of the primary and secondary steel beams of the steel structure shall be combined with the architectural, decoration and installation design of the attic to avoid or reduce the secondary damage to the steel structure in the process of decoration and installation
3. It is not recommended to use hollow steel such as square steel and pipe steel, because it is difficult to brush antirust paint inside the steel, because the cold and hot changes in the north, the rust of steel condensate will pollute the ceiling and wall, and seriously endanger the safety
4. The layout of the steel structure shall be clear and the force transmission route shall be clear and simple. Since the steel structure itself has obvious stress and vibration, it is necessary to analyze and calculate accurately, strictly control the structural deformation and vibration frequency, ensure the visual beauty of the structure, eliminate the resonance between the structure and human activities, and avoid the shear fatigue damage of the structure caused by the resonance phenomenon, At the same time, this can guarantee the comfort in the use process
5. Generally, we have 10, 12, 14 and 16 specifications to choose from for the purchase of steel (channel steel and I-beam steel). No matter what specification we choose, it is recommended to use "national standard" steel because its steel quality and specification are superior to "non-standard steel". The non-standard steel has high hardness, brittle steel, poor ductility, difficult to cut and punch
6. Before fixing the channel steel, the side against the wall of the channel steel shall be painted with antirust paint, but other parts shall be painted after welding, otherwise the welding work will be affected
For steel structure construction, attention shall be paid to the same specification of I-beam and channel steel, and "full welding" shall be selected. The main keel shall be complete steel, and intermediate welding is strictly prohibited
There are many objective factors affecting the steel structure in nature, so it is necessary to select the type of steel structure and make corresponding protective treatment according to the geographical environment and climate when building the steel structure. In the process of steel structure installation and manufacturing, every link and every detail are closely linked, so the construction technicians should have enough patience to ensure the quality of each link, Finally, a safe and reliable home will be returned to the employer.
