Description

Technical Field

[0001] The utility model relates to the technical field of steel bar truss floor decking plates, in particular to a steel bar truss floor decking plate free from dismantling of bottom formwork. Background Art

[0002] The steel truss floor deck is a truss made of steel bars as the upper chord, lower chord and web, connected by resistance spot welding, which is called a steel truss. The steel truss and the bottom plate are connected by resistance spot welding to form a combined load-bearing plate called a steel truss floor deck. Mechanized production is achieved, which is conducive to uniform spacing of steel bars and uniform thickness of concrete protective layer, and improves the construction quality of the floor. Prefabricated steel truss floor deck can significantly reduce the amount of on-site steel bar binding work, speed up the construction progress, increase construction safety assurance, and achieve civilized construction. In recent years, the forms of steel truss floor decks have become more and more diversified. The steel truss and the bottom plate are connected by resistance spot welding to form a combined load-bearing plate called a steel truss floor deck without dismantling the bottom formwork.
