Installation method of grid structure

更新時(shí)間:2020-12-07 09:02:42?點(diǎn)擊:54733 ? Grid Knowledge

The grid structure is a common structural form of modern large space buildings. After more than 20 years of development, the grid structure has formed a unique process theory from design to installation. Especially the installation of the grid, according to different usage scenarios, different installation environments, and different materials have different installation methods. The editor of Huahai Steel will introduce the commonly used grid installation methods for you!

First of all, the most commonly used method for grids is the high-altitude bulk method. This method is suitable for various types of grids with bolted nodes, and the overhanging construction method with fewer supports should be adopted;

Secondly, the method of splitting or splitting installation is suitable for grids with small changes in rigidity and force after splitting, such as two-way orthogonal quadrangular pyramids and positive evacuated quadrangular pyramids; splitting or splitting The size of the block should be determined according to the lifting capacity;

Third, the high-altitude sliding method is suitable for the grids such as the quadrangular pyramid, the quadrangular pyramid is evacuated, and the quadrangular pyramid is placed orthogonally in two directions. When sliding, the sliding unit should be guaranteed to become a geometrically invariant system;

Fourth, the overall hoisting method is suitable for various types of nets, and can be moved or rotated at high altitude when hoisting;

Fifth, the overall lifting method is suitable for peripheral support and multi-point support grids, and can be constructed with small machines such as plate lifts and hydraulic jacks;

Sixth, the overall jacking method is suitable for multi-point support grids with fewer fulcrums;

Seventh, when using hoisting or hoisting or jacking installation methods, the position and number of hoisting points should be selected with the following factors:

         1) It should be close to the force condition when the grid structure is in use;

         2) The maximum reaction force of the lifting point should not be greater than the load capacity of the lifting equipment;

         3) The load of each lifting equipment should be close.

The above are the seven commonly used installation methods for grid structures organized by the editor of Huahai Steel Structure for you. If you have grid business needs, the official website of Jiangsu Huahai Steel Structure Co., Ltd. welcomes you to visit, consult and negotiate!
