Key points of steel structure installation in Suzhou

The position of the high-strength bolt shall be reasonable. The construction space of the torque breaker and the torque wrench shall be considered. Do not install the high-strength bolt because the space is too small and the torque breaker and the torque wrench cannot be in place. As a result, the box head of the high-strength bolt cannot be screwed off or the high-strength bolt cannot be tightened.

The high-strength bolt connecting plate shall be arranged symmetrically from top to bottom. Once there were 4 middle contacts above and 6 below. The workshop workers accidentally reversed some of them. I'm sorry to come here.  
If the brick wall of light steel structure is to be maintained, it must be well connected with the construction unit and civil construction unit in advance, because this involves two aspects of civil engineering and steel structure, because the brick wall of civil engineering is likely to be uneven, but the flashing of color steel plate cannot be done too large or too small. As a result, the gap between color steel plate and brick wall is too large or too small, and the flashing of color steel plate and brick wall is difficult to be done well
Industrial and civil building facilities built with steel are called steel structures. Steel structure engineering has the following hot spots:
1. The steel structure building has light weight, high strength and large span;   
2. The construction period of steel structure building is short, and the investment cost is reduced accordingly;  
3. Steel structure building has high fire resistance and strong corrosion resistance;  
4. The steel structure building is easy to move and has no pollution.
1. Overall collapse, solution: pay attention to the installation sequence and ensure that the temporary support is installed properly;  
2. The weld quality is not qualified. Solution: the weld requiring flaw detection must be welded by skilled welders
3. The anchor bolt of column base is not embedded accurately and cannot be installed. Method: measure accurately and fix firmly when pouring concrete.
