crashing sound preventing structure of building

摘要

The present invention relates to a floor impact sound protection structure of a building, in the floor impact sound protection structure of a building, the concrete slab layer for separating and partitioning the upper and lower floors of the building; A damping layer made of a damping sheet having adhesiveness to be adhered to the concrete slab layer; A bottom plate and ribs formed on an upper surface of the bottom plate to form a lattice or honeycomb space portion, wherein the bottom plate facing the space portion has a through hole having a cross-sectional area smaller than the cross-sectional area of the space portion. A constraining member integrally squeezed and fixed to the damping layer while the bottom plate is buried in the upper portion of the damping layer; And a filler filling the space of the restraining member and covering the upper portion of the restraining member.;By implementing the present invention, it is possible to prevent the floor impact sound of the upper floor of the building from being transmitted to the lower floor, and to secure a comfortable living environment, thereby securing reliability from the tenant, and to integrate the damping layer that is pressed and fixed to the slab layer. Filled restraint layer is to increase the rigidity of the concrete structure has a composite function, it is possible to improve the durability of the building by preventing the occurrence of cracks.;Damping layer, concrete slab, restraint member, filler
