The present invention relates to an inter-layer noise absorbing structure of a building to reduce the inter-layer noise and vibration of the building, and more particularly, a double layer on the bottom surface of the finishing mortar layer formed on the floor slab of the building and the bubble layer formed directly under the flooring material. The present invention relates to an inter-layer noise and vibration absorbing structure of a building to install a noise / vibration absorber layer composed of a laminated structure so as to absorb noise or vibration between layers of a building construction so as to lead a more comfortable communal life.

Generally, in the case of apartment houses such as apartments and villas, various types of shock / noise / vibration reducing materials are used between floors to minimize noise generation between floors above and below for a comfortable shared life (hereinafter referred to as "floor noise"). .) The existing interlayer noise members are mostly made of sponge or elastic rubber material, which is installed just below the foam concrete in the upper part of the floor slab. It blocks and absorbs the impact sound and other noise from the upper layer to be transmitted to the lower layer.

However, since the conventional interlayer noise member is simply a flat plate-shaped elastic material having a certain thickness, it depends on the soundproofing or dustproofing characteristics inherent in the material itself, and thus does not achieve the desired soundproofing or soundproofing effect. In order to enhance the effect, there is a disadvantage in that the thickness of the interlayer noise member becomes thick.

In addition, as the thickness of the interlayer noise member becomes thicker, the construction workability is deteriorated, and the construction cost for the interlayer noise blocking is increased, thereby increasing the overall cost. For example, the Republic of Korea Utility Model Publication No. 329711 is the noise blocking member.

On the other hand, in the construction site, the various floor noise members are installed by hand after the curing of the concrete floor slab is completed. there was. In addition, when a person walks on the laid interlayer noise member, it may crumble and fail to be of high quality construction.

The present invention has been made in view of the above point, and an object of the present invention is to provide an inter-layer noise and vibration absorbing structure of a building that can more effectively block the noise and vibration transmitted from the upper floor.

Another object of the present invention is to provide an interlayer noise and vibration absorbing structure of a building which improves construction workability by varying the hardness of the surface of the interlayer noise member and the surface of the interlayer noise member facing the top of the slab.

The object of the present invention as described above is achieved by forming a kind of buffer structure between the bubble layer and the floor slab layer to absorb and block the noise and vibration generated from the top.

The interlayer noise and vibration absorbing structure according to the present invention has a finishing mortar layer formed by embedding a heating pipe on an upper side of a floor slab installed between floors of a building, and a bubble layer formed by mixing a foamed resin and concrete at a lower part of the finishing mortar layer. The interlayer noise member is interposed between the bubble layer and the bottom slab, and the interlayer noise member has a three-stage laminated structure, the first absorbent layer comprising a hard synthetic resin foam from the top, The second absorbent layer composed of an air-containing layer and a soft synthetic resin foam is sequentially laminated in contact with each other, and the air-containing layer is characterized in that the protrusions and the recesses formed of the hard synthetic resin foams are regularly crossed.

Here, the air-containing layer may be produced by arranging cores in a synthetic resin foam material at a predetermined interval and removing the cores after foaming is completed and cutting to a predetermined thickness.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention.

1 is a cross-sectional view of the interlayer noise and vibration absorbing structure according to the present invention, Figure 2 is a perspective view showing an embodiment of the interlayer noise member in the interlayer noise and vibration absorbing structure according to the present invention, Figure 3a and 3b is a perspective view and a cross-sectional view showing another embodiment of the interlayer noise member in the interlayer noise and vibration absorbing structure according to the present invention, Figure 4 is another embodiment of the interlayer noise member in the interlayer noise and vibration absorbing structure according to the present invention Figure 5 is a plan view and a cross-sectional view showing the form, Figure 5 is a partial cutaway perspective view showing an example of manufacturing the air containing space of the interlayer noise member in the interlayer noise and vibration absorption structure according to the present invention.

As shown in the figure, the interlayer noise and vibration absorbing structure of the building according to the present invention is a finishing mortar layer 230 is formed by the heating pipe 230a is embedded in the upper side of the floor slab 200 is installed between the floor of the building And a bubble layer 270 formed by mixing foamed resin and concrete in a lower portion of the finishing mortar layer 230, and the interlayer noise member 300 between the bubble layer 270 and the bottom slab 200. The interlayer noise member 300, which is a characteristic constitution of the present invention, is a three-layered laminated structure.

The interlayer noise member 300 having the stacked structure of three levels will be described in detail with reference to FIGS. 2 to 4.

In the interlayer noise member 300 according to the present invention, the first absorbent layer 310, the protrusion 350b, and the recessed portion 350a, which are made of a hard synthetic resin foam from the top, are formed to intersect with the first absorbent layer 310. It includes an air containing layer 350 which is located in contact. In addition, the lower portion of the air-containing layer 350 is in contact with the bottom slab 200, the second absorbent layer 330 is composed of a synthetic resin foam that is softer than the material of the first absorbent layer 310.

The first absorber layer 310 and the air-containing layer 350 means that the value measured by "Showa C hardness meter" (C TYPE SHORE HARDNESS TESTER) is 70 ± 5 or more. In addition, the second absorbent layer 330 positioned above the bottom slab 200 means that the value measured by "Showa C hardness meter" is 50 ± 5 or less. The hardness of the first absorbent layer 310 is limited to 70 ± 5 or more in order to prevent the foam from dents or breaks even when a person steps on it and blocks the sound waves transmitted from the top. To improve sound insulation. In addition, the reason for limiting the second absorbent layer 330 to 50 ± 5 or less is that the second absorbent layer 330 is the bottom slab 200 even though the surface of the floor slab is unevenly cured. The first absorbent layer 310 and the air-containing layer are disposed to have a different density (hardness) from the first absorbent layer 310 and the air-containing layer 350 to be in close contact with the surface of the work. This is to minimize the noise and vibration transmitted to the lower layer by absorbing the noise passing through the 350.

Here, the air-containing layer 350 is a protrusion 350b and the recessed portion 350a are formed to have a constant air-containing space therein, the shape of the protrusion is square (see Fig. 2), rectangular (see Fig. 3) or parimide Type (see FIG. 4), and the like. In either case, the recessed portion 350a is formed separately from the protrusion 350b. Of course, the existing interlayer noise member also has an air space inside the air bubbles, but the air bubbles inside are irregularly formed during the foaming process. Since it can be concentrated, it is difficult to produce the effect of dustproof and soundproof efficiently. On the other hand, when the protrusions and the recesses are regularly formed as in the present invention, the noise and vibration are evenly spread and transmitted to the interlayer noise member 300, so that the effect of dustproofing and soundproofing can be efficiently achieved. In addition, considering the characteristics of the parts in contact with each layer and workability during construction, the upper layer is made of hard furnace and the lower layer is made soft so that each layer functions functionally, thus improving convenience and dustproofing and soundproofing efficiency. In fact, according to the present applicant's experiments, the result of the comparative experiment between the existing layer noise member and the layer noise member by the noise absorbing structure of the present invention proved that the vibration and noise blocking effect is more than twice as good.

On the other hand, the air-containing layer 350 is formed by placing the rod-shaped core at a predetermined interval in the space filled with the foam raw material resin and then foamed to remove the core and then to form the recessed portion (350a) at a predetermined interval therein Cutting to thickness can be used (see FIG. 5).

On the other hand, the synthetic resin foams usable in the present invention may be used all known foams such as polyurethane foams, polyethylene foams, polystyrene foams or mixtures thereof.

The interlayer noise and vibration absorption structure of the building according to the present invention described above is formed by the interlayer noise member manufactured by the existing foamed resin by forming the upper and lower layers of the interlayer noise member with different hardness and forming an air-containing layer therebetween. Excellent soundproofing and dustproofing effect can be achieved at construction.

In addition, considering the characteristics of each layer and the workability during construction, the upper floor part is hard and the lower part is soft, so that each layer functions functionally, thus improving convenience and dustproofing and soundproofing efficiency. .

As described above, the interlayer noise and vibration absorbing structure of a building according to the present invention forms a predetermined space for noise and vibration and thermal insulation between the interlayer noise absorbing members to be stacked to absorb shocks or noises by a minimum thickness. Of course, it creates a thermal insulation space to bring about the effect of keeping warm, and increases the absorption effect of shock and noise by stacking porous members, and reliably absorbs not only the noise or vibration caused by the impact from the upper layer but also general living noise. As a result, it is possible to block the problem of disputes caused by noise between the upper and lower floors in the multi-family house, as well as bringing useful effects such as enabling a more comfortable life.
