Description

Floor impact sound reduction dry floor structure and construction method using same {FLOATING FLOOR STRUCTURE FOR REDUCING OF FLOOR IMPACT SOUND AND CONSTRUCTING METHOD USING THE SAME}

The present invention relates to a floor impact sound reduction dry floor structure and a construction method using the same.

The majority of apartments or houses are constructed in a multi-layered structure in which concrete walls and floors are connected to each other. For example, the apartment has a structure in which a cushion pad is disposed on the slab, foamed concrete and heating pipes are laid, and cement mortar is poured to form a concrete layer of a certain thickness.

Such a conventional floor structure has a problem that noise and weight impact sounds generated in the upper layer are transmitted to the lower layer as they are not inserted into the filling material or the noise reduction member, which may reduce the impact or noise. Such noise between floors becomes a reason for discord among neighboring households in apartment houses, and problems such as verbal abuse and assault occur due to noise between floors.

In order to solve such problems, floor structures and sound absorbing materials have been developed to reduce noise between floors, and constructions with floating floor structures capable of preventing floor noise and shortening of air are increasing.

This can minimize the compression on the load acting on the base member 120 to prevent the imbalance in the floor structure.

As shown in FIG. 2, a coupling groove corresponding to the shape of the lower sound absorption unit 130 is formed in the base member 120, and the lower sound absorption unit 130 may be inserted into the coupling groove. When the lower sound absorption unit 130 is coupled to the coupling groove, the lower sound absorption unit 130 may prevent horizontal movement by the coupling groove to stably form the floor structure.

In addition, in order to prevent horizontal movement of the lower sound absorbing unit 130, the base member 120 and the lower sound absorbing unit 130 may be coupled by a piece, a bonding agent, or the like.
