A fixed installation structure and method for a profiled steel plate composite floor insulation board

Abstract

The invention relates to the technical field of buildings, in particular to a profiled steel sheet composite floor insulation board fixed installation structure and method. The structure comprises a concrete wallboard. One face of the concrete wallboard is fixedly connected with one face of a profiled steel sheet, multiple screws are fixed to the face, away from the concrete wallboard, of the profiled steel sheet, one end of each screw is fixedly connected with the profiled steel sheet in a welded mode, and the other ends of the screws penetrate through an insulation board and then are locked and fixed through nuts. The profiled steel sheet composite floor insulation board fixed installation structure and method have the advantages that one end of each screw is fixed to the profiled steel sheet in the welded mode, the other ends of the screws penetrate through the insulation board and then are fixed through the nuts, the structure is simple, installation is convenient, fixation is stable and firm, no damage is caused to the profiled steel sheet, no slurry flow phenomenon is caused to pouring concrete, and the quality of a whole composite floor is guaranteed.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a structure and method for fixing and installing a thermal insulation board of a combined floor slab of a profiled steel plate. Background technique [0002] Adding insulation layers to the walls of buildings can effectively reduce the energy consumption of air conditioners, and has become an important measure for energy conservation and emission reduction. Existing methods for installing the insulation layer generally include fixing with expansion bolts or nails, fixing with reserved steel bar heads and fixing with adhesives, but all of the above methods have shortcomings. For the profiled steel plate composite floor, if expansion bolts or nails are used for fixing, it is difficult to penetrate the profiled steel plate, making construction difficult and low construction efficiency. If the reserved steel bar head is used for fixing, before the floor concrete on the profiled st...

AI Technical Summary

Problems solved by technology

For the profiled steel plate composite floor, if expansion bolts or nails are used for fixing, it is difficult to penetrate the profiled steel plate, the construction is difficult and the construction efficiency is low

If the reserved steel head is used for fixing, before the floor concrete on the profiled steel plate is poured, a large number of holes must be drilled on the profiled steel plate, resulting in serious flow during concrete pouring, which is not conducive to the quality of the concrete floor

Due to the smooth surface of the profiled steel plate, it is difficult to fix the insulation board firmly with adhesive when it is fixed with adhesive, and it is prone to quality problems such as hollowing, cracking and even falling off
