Prefabricated steel truss floor deck

A truss made of steel bars as the upper chord, lower chord and web members and connected by resistance spot welding is called a steel bar truss.

The combined load-bearing slab in which the steel truss and the bottom plate are connected by resistance spot welding is called the steel truss floor bearing plate.

Advantages: mechanized production is realized, which is conducive to the uniform spacing of the steel bars and the uniform thickness of the concrete protective layer, which improves the construction quality of the floor slab. The prefabricated steel truss floor deck can significantly reduce the amount of on-site steel tying works, speed up the construction progress, increase construction safety guarantees, and realize civilized construction. The prefabricated template and connecting parts are easy to disassemble and assemble, can be reused many times, save steel, and meet the national energy conservation and environmental protection requirements. The self-developed products of the steel structure are equipped with automatic production equipment, which greatly improves labor productivity and effectively reduces product costs. It has also compiled product production enterprise standards, design manuals, joint structure atlases and construction manuals. The product has been tested by the Civil Engineering Test Center of Zhejiang University and has undergone a number of engineering applications. Its performance can meet the requirements of the load-bearing capacity and deformation of cast-in-place reinforced concrete floors. Fabricated steel structure

Disadvantages: easy to damage during transportation.
