Description

Technical Field

[0001] The present application relates to the field of floor deck connection, and in particular to a steel structure floor deck connection node. Background Art

[0002] Floor decking is a pressed steel plate that supports floor concrete and is widely used in the construction of steel structure buildings. Before laying the floor decking, a steel truss needs to be set on the top of it, and then the steel truss and floor decking are welded and fixed by welding equipment to improve its bearing capacity so that it can withstand the dead weight of wet concrete and construction loads during the construction phase.

[0003] At present, most steel processing construction projects require the use of floor decking. When welding and fixing the steel trusses and the floor decking, it is easy for the steel structure to be misaligned, resulting in welding errors, which in turn affects the subsequent service life of the floor decking. In addition, the misaligned floor decking is not convenient to recycle. Therefore, a steel structure floor decking connection node is needed, which can fix the steel trusses and the floor decking through fixing clips, so as to avoid dislocation when the user welds the steel trusses and the floor decking, and prevent the steel trusses from being unable to be adjusted after being misaligned at the top of the floor decking.
