The present invention relates to a floor noise reduction material of a building, and more particularly, to be installed between floors of a building to completely block noise generated between floors, thereby improving the customer satisfaction of the floor noise reduction material of a building. It is about.

In general, the impact sound that is applied to the building structure of apartment houses such as apartments and villas is transmitted to all directions of solid sound generated by people walking, opening and closing of doors, moving objects, starting or stopping equipment, etc. This causes the surface of the building structure to vibrate, as well as being switched to airborne sound, which is perceived as noise when it is heard by people around it.

For example, the impact of falling objects on the floor or the sound of moving chairs generates solid sound, which is transmitted through the floor slab and the walls to other adjacent rooms, especially the floor slab. The propagation through the floor below is called interlayer noise.

Nowadays, as these inter-floor noise problems are seriously raised in multi-unit houses, regulations on housing construction standards have been strengthened and revised.

The regulations stipulate that the floor impact sound between floors should be 58 decibels (db) or less, and the heavy impact sounds should be 50 decibels (db) or less, or have a standard floor structure as determined and announced by the Minister of Construction and Transportation.

As such, conventional interlayer floor structures for reducing and minimizing severely raised interlayer noise have been proposed. Such conventional interlayer floor structures are based on the concrete slab 1, as shown in FIG. Lightweight foam concrete layer (2) is formed on the upper part, heating pipe (3) and finishing mortar layer (4) is formed on the upper part, and the floor decorative layer (5) made of decorative materials such as monolium, solid wood, and tiles thereon (5). It is composed of

In the interlayer floor structure of the above structure, the lightweight foam concrete layer 2 formed on the concrete slab 1 is responsible for attenuating the impact sound or noise, but the effect is insignificant.

For this reason, in order to more effectively block noise and impact, a construction method for forming an interlayer shock-absorbing material between the concrete slab and lightweight foamed concrete is disclosed.

The conventional interlayer shock sound absorbing material 10 is provided as various structures, and typically has hard styrofoam materials 11 and 12 having a predetermined thickness in the upper and lower portions as shown in FIG. It is provided with a structure in which the intermediate sound insulating material 3 made of polyester material having a large gap is sandwiched in a sandwich form.

However, the above-described conventional interlayer shock sound absorbing material also does not reliably alleviate the impact, thereby failing to completely reduce the interlayer noise of the building.

Therefore, the present invention has been devised in view of the above problems, by additionally installing a rubber member having excellent elasticity at regular intervals in the lower member located at the bottom, so as to reduce the inter-layer noise of the building more reliably. The purpose is to provide noise reduction materials for a building.

The present invention for achieving the above object, the upper member made of a large pore polyester material or expanded polystyrene or expanded polypropylene material; An intermediate member which is laminated under the upper member and is made of polyethylene or PVC or polypropylene, and has a hollow part and has an air layer; A lower member laminated under the intermediate member and made of expanded polystyrene or expanded polypropylene or polyester; It is inserted into the lower member to be fixed at a predetermined interval to finally absorb the impact, the insertion portion is fixed to the lower member and the contact surface portion extending from the insertion portion and protruding from the lower member by a certain height Characterized in that it comprises a plurality of rubber members.

In addition, it is preferable that the contact surface portion is formed to have a larger diameter than the insertion portion so as to be in close contact with the insert surrounding the lower member into which the insertion portion is inserted.

In addition, a plurality of irregularities are formed in the circumferential direction at a predetermined interval on the flat portion of the contact surface portion, grooves are formed along the circumference at a predetermined depth between the irregularities, and a straight exhaust groove connecting the grooves is constant. It is preferable that a plurality are formed at angular intervals.

Meanwhile, a member made of expanded polystyrene or expanded polypropylene or polyester may be further stacked on the upper member.

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

3 is a bottom perspective view showing the configuration of the noise reduction material of the building according to the present invention, Figure 4 is a cross-sectional view of FIG.

As shown, the inter-layer noise reduction material of the building according to the present invention is made of a polyester material having a large void and made of a soft upper member 20 and a polyethylene (PE) or PVC or polypropylene (PP) material. And an intermediate member 30 having a hollow portion to have an air layer, a lower member 40 made of expanded polystyrene (EPS) or expanded polypropylene (EPP) material, and a hard member. A portion of the member 40 is inserted into and fixed at regular intervals, and includes a plurality of rubber members 50 to perform a cushioning function.

In this case, the upper member is made of a polyester material, in addition to soft, it may be applied to a hard material made of expanded polystyrene or expanded polypropylene material, on the contrary, the lower member is made of a hard foam made of expanded polystyrene or expanded polypropylene material In addition, a soft material made of a polyester material can also be applied.

The rubber member 50 is formed in a circular shape, the insertion portion 50-1 is fixed to the lower member 40, and is formed extending from the insertion portion and constant from the lower member 40 It consists of a contact surface portion 50-2 protruding as high.

In this case, the contact surface portion 50-2 is formed to have a larger diameter than the insertion portion 50-1, and is closely attached to the state in which the insert portion 50-1 wraps around the lower member 40 into which the insertion portion 50-1 is inserted. Let's go.

On the other hand, a plurality of uneven portions 52 are formed in the circumferential direction at regular intervals on the planar portion of the contact surface portion 50-2.

Therefore, when an impact is applied by the cylindrical grooves 54 formed between the uneven parts 52, the buffering effect is increased.

In this case, it is preferable to form the exhaust groove 56 to cross the uneven parts 52 of the contact surface part 50-2 over about four directions.

That is, when an impact is applied to the interlayer noise reduction material of the building including the rubber member 50, the impact is applied to the contact surface part 50-2 of the rubber member 50, thereby compressing the uneven parts 52. In this case, air existing in the grooves 54 formed between the uneven portions 52 may be compressed to reduce the buffering effect, so that pressure is applied to the uneven portions 52 to prevent this. When applied and compressed, the air present in the recess 54 is allowed to escape to the outside through the exhaust groove 56, so that it is possible to have a more sure cushioning effect.

In the state in which the interlayer noise reduction material of the building having the above structure is installed, when the interlayer noise is generated by the impact, the upper member 20 primarily absorbs the impact and secondly forms the air layer. 4 having the intermediate member 30 having the shock absorbing, the lower member 40 in the third absorbs the shock and at the same time the rubber member 50 installed at the lower member 40 at regular intervals. It is composed of heavy shock absorbing structure to completely block the noise between layers.

In this case, as described above, the contact surface portion 50-2 of the rubber member in close contact with the upper surface of the concrete slab in the rubber member 50 is easily formed by a plurality of irregularities 52 formed in a circumferential shape at a predetermined interval. As well as absorbing shock while being crushed, air existing in the grooves 54 formed between the uneven portions 52 escapes through the exhaust grooves 56, thereby absorbing the shock more reliably. .

On the other hand, Figure 5 is a cross-sectional view of the floor noise reduction material of the building according to another embodiment of the present invention, as shown, the hard member 60 made of expanded polystyrene or expanded polypropylene material on the upper member 20 It can also be added to produce the product.

In this case, the member 60 may be a soft material made of a polyester material.

That is, in the foregoing embodiment, the upper member 20, the intermediate member 30, the lower member 40 and the plurality of rubber members 50 which are fixed to the lower member at predetermined intervals, the upper member ( 20) by providing a product on which the hard member 60 made of expanded polystyrene or expanded polypropylene or the soft member 60 made of polyester is further provided to absorb the impact as a five-layer structure. It is possible to reliably reduce the inter-layer noise.

As described above, according to the floor noise reduction material of the building according to the present invention, a material having excellent shock absorption is laminated in four or five layers to more reliably block the noise between the floors, and to impact the lowermost member. Since the rubber member for absorbing once more is installed, there is a very useful effect that can almost completely block the noise between the floors to satisfy customer satisfaction.
