Abstract
Provided is a thin-wall light steel composite floor slab without dismantling a bottom cast. The thin-wall light steel floor slab without dismantling the bottom cast comprises a plurality of precast sheets, a plurality of cold-formed thin-wall steels and a concrete cast-in-place layer. The precast sheets serve as permanent formworks of composite floor slabs; the cold-formed thin-wall steels as frameworks of the composite floor slabs are at intervals arranged on the precast sheets, and integrated with the precast sheets; the concrete cast-in-place layer is integrated with the precast sheets and the cold-formed thin-wall steels. The precast sheets are used as the permanent formworks of the composite floor slabs, the bottom of the precast sheets is smooth, less post treatment process is provided, and the precast sheets are convenient to install. The combination of the cold-formed thin-wall steel and the precast sheets undertakes working load of construction stage, less temporary supporting is needed when span is large, and floor slabs with different spans are all applied. Joint seams connect two adjacent cold-formed thin-wall steels into a whole through adhesives and connecting pieces. When pouring is finished, the cold-formed thin-wall steels and concretes form a composite construction to be under pressure. The precast sheets used as permanent formworks without dismantling the bottom cast have the advantages of being rapid in construction, convenient to install, good in integrity and good in earthquake resistance.
