Analysis of matters needing attention in building steel structure houses

Due to the simple construction process, good stability and earthquake resistance of steel structure houses, it has won the recognition of the masses. . In the era of advocating green buildings, whether in rural or urban areas, building houses with steel structures seems to be an inevitable trend.

Steel structure houses are assembled from various components. What problems should be paid attention to when building steel structure houses? In order to ensure the quality and stability of steel structure houses. Today, let's discuss some related knowledge about building steel structure houses.

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 steel structure load from damaging the original structure.

2. The layout of the primary and secondary steel beams 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 tube steel, because it is difficult to paint the inside of the steel with anti-rust paint, the temperature changes in the north, and the rust of the steel will pollute the condensed water. Ceilings and walls can 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 and vibration of the steel structure itself, it is necessary to analyze and calculate accurately, strictly control the structural deformation and vibration frequency, ensure the visual appearance 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. , and at the same time, it can ensure the comfort during use.

5. For the purchase of steel (channel steel, I-beam), we generally have 10, 12, 14, and 16 specifications to choose from. No matter which specification you choose, it is recommended to use 'national standard' steel, because its steel quality and specifications are better than 'non-standard steel'.

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

For the construction of steel structure, note that the I-beam and channel steel must be of the same specification, and 'full welding' must be selected. The main keel should be a whole steel, and intermediate welding is strictly prohibited.
