What are the construction methods for the integral installation of steel structure grid engineering?

The integral installation method is to assemble the grid into a whole on the ground first, and then lift it to the design position with lifting equipment to fix it. This construction method does not need a tall assembly bracket, has less aerial work, and is easy to ensure the welding quality, but requires heavy lifting equipment and complicated technology. Therefore, this method is suitable for steel grid structures with spherical joints (especially for grid structures with more bars such as three-dimensional grids). According to the different equipment used, the overall installation methods are divided into multi-machine hoisting method, tie rod method, jack-up method and jack-up method.

Multi-machine lifting method

This method is used for small and medium-sized grid structures with small height and weight.

Pull-out lifting method

At present, the installation of large-scale spherical joint steel tube space truss in China is mostly carried out by pulling rod method. In this method, the grid is assembled on the ground first, and then the grid is hoisted to the top of the column with multiple single-leg tie rods, displaced in the air and installed in place.

Electric spiral lifting method

The electric spiral lifting method is similar to the flat lifting method, and the assembled steel grid structure on the ground is lifted to the design elevation by using the electric spiral elevator used in the flat lifting engineering construction. The advantage of this method is that it does not need large lifting equipment and the construction is simple. If you encounter problems in the installation or production of grid engineering, you'd better consult an experienced steel structure engineering company, especially a professional company for grid engineering construction. Hunan Yinhe steel structure specialty can provide you with detailed services by doing this kind of steel structure engineering.
