Sometimes, because the preparatory work is not done well, the steel structure will have deviations during installation. Once deviation occurs, it may lead to safety accidents during the construction process. So, how should we prevent this from happening? Next, let me introduce measures to prevent deviations in the installation of steel structures.
1. The steel structure entering the site should be spot-checked and measured, and the excessive deformation should be corrected in time, and only qualified to install it.
2. Check and calibrate whether the measuring instrument is intact and whether the measurement verification has expired to ensure the accuracy of the measuring instrument.
3. The steel structure should take into account the compression deformation value of the load on the steel structure and the shrinkage deformation value of the joint weld seam. During the construction, the welding shrinkage deformation is strictly controlled, and the change in foundation settlement is noted.
4. Select the appropriate time measurement to ensure the measurement accuracy.
5. After the steel structure is installed, reliable temporary fixing measures must be taken, or a stable unit should be formed to ensure the safety of the steel structure construction.
6. The steel structure whose installation deviation exceeds the allowable deviation should be adjusted in time. The measurement value should be recorded for the super-difference steel structure that cannot be adjusted. After the design and the consent of the relevant unit, the visa is accepted and filed.
The above are effective measures to prevent deviations in the installation of steel structures. When working, it should be carried out in strict accordance with the operating specifications. Because the installation of steel structure is not a simple small project, it is very necessary to master the construction knowledge of the product.
