However, the concrete non-dismantling steel truss floor decking generally has insufficient edge stiffness, and the two plates are easily misaligned when spliced together, so that decoration and leveling are required later, which increases the difficulty of construction and increases the cost. At the same time, the steel trusses used in the existing non-folding steel truss floor slabs generally have web bars that are bent into a long strip, which makes construction difficult and the production process complicated.
