In recent years, the steel grid has become the most popular building material. Because of the quality, structural and installation of steel grids, steel grids are used everywhere. Today, the editor will introduce the installation process of steel grid.

For the steel structure installation, when the strongest bolt is required, the torque coefficient and the tightening axial force must be retested, and the anti-slip coefficient of the friction surface should be prepared and installed separately. Install the strong bolts to control the construction torque. The tooth length is 2-3 buckles. The strong bolts are not allowed to be used as temporary fixing bolts. The final tightening of the strong bolts must be completed within 48 hours.

The steel structure installation components should be strictly in accordance with the installation process sequence, and a stable frame unit should be formed on the day. When it cannot be formed, a cable wind rope should be added to fix it to prevent collapse accidents. After installing the steel member column and beam in the steel structure, the verticality and height difference shims of the steel column should be adjusted as soon as possible, then the column foot should be closed, and the second grouting should be dense.
