Description

Floor impact sound absorbing member, interlayer floor impact sound blocking slab structure and slab construction method for noise prevention

After the floor panel is covered, then the heating pipe is arranged, and the finishing mortar layer and the floor finishing material are sequentially provided, so that the impact sound generated from the top after construction can be reduced, unlike the conventional slab structure, It relates to a floor impact sound absorbing member that is simple and can reduce construction costs, a slab structure for blocking floor impact sound between floors for noise prevention, and a slab construction method.

In general, when an impact such as a person's walking or falling of an object is applied to the upper floor of an apartment building, the noise radiated into the lower level household through a concrete slab is called floor impact sound.

The inter-floor floor impact sound blocking structure standard for noise prevention refers to a floor structure that has been confirmed and recognized for the performance of the floor impact sound blocking structure, and the performance of the floor impact sound blocking structure is a heavy impact sound (refers to floor impact sound caused by heavy and soft impact) 49db or less, light weight Impact sound (floor impact sound caused by a relatively light and hard impact) 49db or less is confirmed and approved structure.

As shown in Figure 7 of Patent Registration No. 10-114219 (April 25, 2012) as a prior art, after installing a buffer on a concrete slab, lightweight aerated concrete is poured thereon, and the finishing mortar layer and floor finishing material are placed on it again. Although it was possible to reduce inter-floor noise by constructing, there was a problem in that the cost was increased because the construction was complicated and took a lot of time.

As another conventional technology, a piping block for ondol of Korean Patent Publication No. 10-2007-0003729 (January 5, 2007) has been proposed, and the proposed piping block is not only expandable by a fitting structure, but also guarantees a high degree of freedom of the piping line. However, there was a problem in that a gap was generated at the bottom of the pipe block during the concrete pouring process, and due to this cause, vibration or impact force was amplified by resonance.
