Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First, the embodiments described below are embodiments suitable for understanding the technical characteristics of the interlayer noise abatement unit of the present invention. However, the technical features of the present invention are not limited by the embodiments to which the present invention is applied or explained in the following embodiments, and various modifications are possible within the technical scope of the present invention.

2 to 4, the unit-to-layer noise reduction unit 100 according to an embodiment of the present invention includes a flat plate portion 120, and a plate portion 120 integrally bent at an edge of the flat plate portion 120 A panel member 110 having a joining portion 130 formed on an outer side of the flat plate portion 120 and a flexible material having a bent portion 151 joined to a lower surface of the panel member 110, And an anti-vibration member 150 elastically supporting the member 110.

The panel member 110 may be installed at a lower portion of the finishing portion 230 in the floor structure to form a bottom surface, as described later. Preferably, the panel member 110 is made of a vibration proof alloy, so that the energy of the impact sound transmitted from the finishing unit 230 can be dissipated by vibration.

In addition, the flat plate portion 120 may be configured to be in surface contact with the finishing portion 230. As shown in FIG. 3, the flat plate portion 120 may be a rectangular plate-shaped member including a plumbing portion with a corner portion removed.

The joining part 130 is integrally formed by being bent downward from the end of the flat plate part 120. The rigidity of the entire panel member 110 is increased by the bent shape while restraining the edge of the flat plate part 120 . And may be provided to connect the plurality of inter-layer noise reduction units 100 as described later.

The anti-vibration member 150 may be bonded to the lower surface of the panel member 110, and more preferably to the lower surface of the connection member 130. In addition, the anti-vibration member 150 may include a bent portion 151 that is elastically bent. That is, when the load, vibration, or impact sound is transmitted through the panel member 110, the bending portion 151 is elastically bent to absorb the impact, So that transmission to the lower portion can be minimized.

The joining portion 130 may include a first joining portion 131 and a second joining portion 135 bent to form a receiving groove. The first joint part 131 may be formed on two adjacent surfaces of the flat plate part 120 and the second joint part 135 may avoid the first joint part 131, (Not shown).

The second joining portion 135 may have a receiving groove and the receiving groove may be formed in the first joining portion 131 so that the first joining portion 131 can be pressed against the second joining portion 135 And may be formed in corresponding sizes.

Accordingly, when the plurality of inter-layer noise reduction units 100 are horizontally connected as described later, the plurality of panel members 110 can be coupled by sandwiching and assembling the first joints 131 in the receiving grooves. A detailed description of the configuration in which the plurality of panel members 110 are fitted to each other by the joining portion 130 will be described later.

Specifically, the first joint 131 includes a first web 132 bent perpendicularly to the flat plate 120, and a second web 132 parallel to the flat plate 120 at an end of the first web 132. [ A bent first flange 133 may be formed. At this time, the first web 132 may be bent vertically downward from the end of the flat plate 120.

The second joining portion 135 includes a second web 136 bent perpendicularly to the flat plate portion 120 and a second web 136 bent at an end portion of the second web 136 in parallel with the flat plate portion 120. [ And a leaf 138 bent perpendicularly to the end of the second flange 137 to define the receiving groove.

At this time, the second web 136 can be bent vertically downward from the end of the flat plate 120, and the leaf 138 is bent upward at the end of the second flange 137, The receiving groove of the second joint portion 135 can be formed. The first web 132 and the first flange 133 may be received in the receiving groove.

The length of the second flange 137 may correspond to the length of the first flange 133 so that the first joint 131 may be joined to the second joint 135 by interference fit .

The end of the leaf 138 may be inclined toward the second web 136 so that the first joining portion 131 is firmly coupled to the second joining portion 135. Accordingly, the first joint portion 131 can be firmly fitted to the second joint portion 135 without any additional fixing means, thereby improving the workability and workability.

Meanwhile, the panel member 110 may be formed of a vibration-proof alloy which reduces vibration and noise as described above.

That is, the panel member 110 is adapted to absorb vibration and noise generated by a walking load, an impact load, and the like on the floor into internal heat energy and absorb it. For example, the panel member 110 may be made of a Fe-Mn alloy, (Sonostone), a Cr-Al-Fe alloy (sementaloy), an Fe-Cr-Al alloy, or the like.

However, the type of the anti-vibration alloy constituting the panel member 110 is not limited to the above, and various modifications may be made if the vibration and noise transmitted to the panel member 110 are attenuated.

The panel member 110 and the dustproof member 150 are joined to each other and the panel member 110 itself is also made of vibration and noise It is possible to maximize the effect of reducing the vibration and noise generated by the walking load or the impact load at the upper portion of the finishing portion 230 when the bottom structure is used.

Particularly, since the vibration reduction structure applied to the dry method of the conventional floor structure is separated from the floor panel, the vibration and noise are not effectively absorbed and practicability is not achieved. On the contrary, in the embodiment of the present invention, The panel member 110 can be easily assembled and installed in a dry process. At the same time, the interlayer noise reduction unit 100, in which the panel member 110 is assembled, is provided so as to reduce vibrations, .

The anti-vibration member 150 may be made of a soft steel material and may be bent in a U-shape so that the upper surface of the anti-vibration member 150 may be joined to the lower surface of the joint 130.

The anti-vibration member 150 may be joined to a lower surface of the joint 130 by a fastening member, and more preferably to a lower surface of the second joint 135. However, the connection of the anti-vibration member 150 is not limited thereto. For example, the anti-vibration member 150 may be bonded to the lower surface of the connection part 130 by welding or the like. The anti-vibration member 150 may be continuously provided on the lower surface of the joint 130 to correspond to the length of the joint 130, but the present invention is not limited thereto and a plurality of anti-vibration members 150 may be intermittently joined.

At this time, the U-shaped bent portion 151 functions as an elastic spring to absorb and mitigate the impact transmitted from the panel member 110. That is, when the load is transmitted from the upper portion, the bending portion 151 is flexibly deformed to absorb the impact and then recovered. Thus, when the interlayer noise reduction unit 100 is used in the floor structure, Thereby preventing the load from being directly transmitted to the bottom slab 210.

The vibration damping member 150 may further include a cushioning member 170 bonded to the lower surface of the vibration preventing member 150 and made of a flexible material.

At this time, the buffer member 170 may be adhered to the lower surface of the vibration-preventive member 150 with an adhesive or the like, and the buffer member 170 may be made of a flexible material such as vibration-proof rubber.

Accordingly, the buffer member 170 can provide an effect of suppressing the generation of additional impact sound by the direct surface contact between the vibration-proof member 150 and the floor slab 210. [

2 and 3, the flat surface portion 120 may be chamfered with respect to a portion of the corner surface 121 on which the plumbing hole 123 is formed.

As a result, when the piping member 250 is inserted into the insertion groove 130a provided in the joint 130, the piping member 250 can be bent and zigzag easily, (See FIG. 7).

Alternatively, the finishing unit 230 may be a floor finishing material made of a precast concrete panel, and may be installed so as to be placed on an upper surface of the floor panel 220 by a dry method.

However, according to the conventional wet method or semi-dry method, the finishing mortar must be installed in the finishing part 230 to fill the pipe member 250 installed in the bottom panel part 220. However, According to the example, as described later, since the pipe member 250 is inserted into the insertion groove 130a of the bent portion 130, it is possible to omit the finishing mortar.
