Description

Interfloor noise prevention structure {Interfloor soundproof structure}

The present invention relates to an inter-floor noise prevention structure, and more specifically, to an inter-floor noise prevention structure with an improved structure.

In general, concrete slab structures can be said to be good sound insulators because they block sound waves transmitted from the air well, but when shock or vibration is applied directly to such concrete structures, they change into solid propagated sound and are hardly attenuated and are transmitted to other adjacent households, creating noise. It has the characteristic of being radiated.

Recently, the quality of an individual's residential life has been greatly reduced due to the noise generated between the upper and lower floors of apartment complexes, and as a result, civil complaints have become frequent. Inter-floor noise refers to solid-transmitted noise caused by people walking and falling objects on the upper floors of apartments (apartments, villas, multi-family houses, etc.) and air-transmitted noise generated from various sound devices, which travels up and down through the floor slab or walls. This refers to sounds that radiate into adjacent households on the left and right and act as pollution in everyday life.

At this time, the problem is the floor impact sound, which is a light noise such as the sound of pulling a chair that generates a lot of high-frequency sound, and a heavy impact sound that generates a lot of low-frequency thumping sound such as adults walking and children jumping.

After the elastic support portion 50 is installed on the panel body 32, when an external force is applied, the plurality of support legs 58 are opened in the radial direction and the plurality of elastic stoppers 56 are configured to narrow with respect to each other. In this process, when an external force is excessively applied, the separation space 56a between the plurality of elastic stoppers 56 narrows, causing contact with each other or with the insertion portion 54, and the support leg 58 no longer occurs. ) can function as a stopper to prevent it from opening.

The following describes the installation method of the inter-floor noise prevention structure of the present invention.

First, the buffer panel 30 to which the elastic support 50 is coupled and the insulation panel 22 are sequentially installed on the slab (S). Afterwards, the intermediate mortar (12) can be placed on the top of the vibration-proof module (20), and the heating pipe and finishing mortar (14) can be constructed on the top of the intermediate mortar (12).

The inter-floor noise prevention structure (1) of the present invention installed in this way has the advantage of being able to reduce shock and noise transmission from the upper floor as a buffer space is formed by the buffer panel (30), and the buffer panel (30) and the elastic member By constructing it as a separate type, there is an effect of reducing shock and noise transmission compared to the integrated type through the fine air gap between them.
