Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, and in particular to a Z-shaped bracket device at the partial drop support of a truss floor deck. Background Technology

[0002] In prefabricated building structures, floor slabs are typically made of steel truss floor decking. However, in areas where the slab is partially lowered, traditional construction methods require separate formwork for concrete pouring. This method involves complex procedures, involves high formwork, poses high safety risks, and impacts on-site installation schedules and safety.
