Measures to prevent deviation in steel structure installation
Author：
Sometimes because the preliminary preparations are not done well, there will be deviations in the installation of the steel structure. Once the deviation occurs, it may lead to safety accidents during the construction process. So, how should we prevent this from happening? Next, I will introduce the measures to prevent deviations in the installation of steel structures.
1. The steel structure should be checked and measured when it enters the site. If the deformation is out of tolerance, it should be corrected in time, and it can be installed only after it is qualified.
2. Check and calibrate whether the measuring instrument is in good condition, whether the metrological verification has expired, and ensure the accuracy of the measuring instrument.
3. The compression deformation value of the load on the steel structure and the shrinkage deformation value of the joint weld should be considered during the production of the steel structure. During the construction, the welding shrinkage deformation should be strictly controlled, and attention should be paid to the change of the foundation settlement.
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 must 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, and the measured value should be recorded for the out-of-tolerance steel structure that cannot be adjusted.
The above are effective measures to prevent deviations in the installation of steel structures. When working, they 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 relevant construction knowledge of the product.

Rock wool, Glass Wool Color Steel Composite Panel
The rock wool and glass wool color steel surface composite panels are made of rock wool with vertical filamentous fibers as the core material, and color coated color steel plates as the surface layer, which are bonded with high-strength adhesives after being pressed by an automatic continuous forming machine. made. Because the color steel plate and the core plate rock wool are both non-combustible bodies, their fire resistance is better. We can do more: aluminum-galvanized light sheet, stainless steel, galvanized sheet and other surface layer composite panels can be processed and produced according to user needs.
