Construction method of interlayer noise barrier structure and interlayer noise barrier structure

摘要

The present invention can significantly shorten the construction period by omitting the lightweight foamed concrete layer and also reduce the construction cost. In particular, it is excellent by providing a space layer between the floor slab layers even after a predetermined period of time after construction. Laminating each of the air caps on the underside of each insulating material to have sound insulation efficiency; Perforating each of the coupling holes at equal intervals in each of the heat insulating materials to which the air caps are laminated; The upper end protrudes to the upper surface of the insulating material to support the finished mortar layer to prevent sinking and depression of the insulating material in each of the coupling holes, and the lower end protrudes more than the bottom surface of the insulating material, and an air cap is interposed between the insulating material and the floor slab layer. Joining the members; Applying a side cushioning material to each wall surface of the floor slab layer; Arranging such that the air cap of each heat insulating material to which the support member is coupled is positioned as a floor slab layer; And forming a finished mortar layer by pouring mortar after placing a pipe on the top of each of the arranged insulating materials, and providing a construction method of the interlayer noise blocking structure and the interlayer noise blocking structure. Accordingly, it has an effect of maximizing construction efficiency, excellent economical efficiency, and an effect of remarkably reducing inter-floor noise.
