Recently, as multi-story apartment houses such as apartments have become common, disputes between neighbors due to noise between floors are emerging as a serious social problem.

In general, in the case of multi-story buildings such as apartments, most of the air propagation sound is blocked by the concrete slab structure, but when an impact or vibration is directly applied to the floor by a person walking or dropping an object from the upper floor, the solid propagation sound It has a characteristic that it is hardly attenuated by changing to a low level and radiates to the lower floor or adjacent households through floor slabs, ceilings, and walls.

The floor impact sound is a light impact sound that generates a lot of high-frequency components, such as the sound of dropping a bowl or object or moving a chair, and a heavy impact sound that generates a lot of low-frequency components such as a child's running sound and an adult's walking. are distinguished

Meanwhile, in recent years, due to the rise in land prices and the convenience of living, multi-story apartment houses such as apartments and villas have become common, and disputes between neighbors due to noise between floors are emerging as a serious social problem.

As shown in the drawing, the ondol floor structure 10 (hereinafter referred to as 'ondol floor structure' for convenience of description) for reducing noise between floors using the non-hardening filling layer of the present invention is an interfloor installed on the slab 100 of a building. As an ondol floor structure 10 for noise reduction, the ondol floor structure 10 according to the present invention includes a non-hardening filling layer 20 , a buffer panel 30 , a heating pipe part, and a heating mortar layer 50 . can be

The non-hardening filling layer 20 is disposed on the upper side of the slab 100 and serves to absorb interlayer noise.

The non-hardening filling layer 20 may be formed by mixing the powder member, sand and water and then stirring.

Specifically, the non-hardening filling layer 20 may be used by mixing the powder member, sand, and water in a weight ratio of 1 to 70:50 to 200:1 to 100, respectively.

The powder member is ferronickel slag, blast furnace slag, copper slag, limestone fine powder, stone powder, fly ash, bottom ash, steelmaking slag, silica, paper ash, desulfurized gypsum, one or a mixture of two or more selected from calcium carbonate. Can be used.

The powder member serves to pressurize the filler mixture that is mixed with sand and water to form the non-hardening filler layer to the required floor of the building.

If the powder member is not included, it is impossible to pressurize only the sand and water.

In addition, in the present invention, the ferronickel slag in the powder member is quenched by quenching the molten ferronickel slag using high-pressure water. It is classified into ferronickel slag obtained by making the ferronickel slag, and in the present invention, the water-quenched quenched ferronickel slag can be used, but the present invention is not limited thereto.

In the present invention, as the powder member, it is preferable to use a fine powder having a high density of the ferronickel slag having a specific surface area of 1,000 to 8,000 cm ² /g for smooth feeding of the filler.

The non-hardening filling layer is a mixture of powder, sand, and water, moved to the slab of the building to be poured through a pump or a special pump vehicle, and the non-hardened filling layer formed by pouring the water gradually evaporates over time. And only sand remains.

Noise is absorbed (absorbed) by the voids formed between the powder member and the sand and the powder member and the sand of the non-hardening filling layer, thereby preventing the noise from being transmitted to the lower layer or the noise from the lower layer being transmitted to the upper layer.

In addition, the powder member component supports the load to improve the bearing capacity, and it is possible to reduce the pressing phenomenon due to the load. That is, by making the particles of pernickel slag, blast furnace slag, copper slag, limestone fine powder, stone powder, fly ash, bottom ash, steelmaking slag, silica, paper ash, desulfurized gypsum, and calcium carbonate smaller than the particles of sand, It is possible to improve the bearing capacity and reduce the pressed shape.

Hereinafter, the present invention will be described in more detail through examples.

[Example 1]

First, the slab structure was manufactured by reinforcing reinforcing bars in a double-layer structure with a width of 50 cm, a length of 65 cm, a height of 60 cm, a wall thickness of 80 mm, and a slab thickness of 80 mm in the same way as A and B. The slab height was 30 cm from the floor and was cured for 28 days. (See Fig. 9)

The flow value was measured using an uncured filler obtained by mixing and stirring 23 parts by weight of fine pernickel slag powder, 70 parts by weight of sand, and 3 parts by weight of fine limestone powder on the upper part of the structure slab and mixing it with 34 parts by weight of water. It was 255mm as shown.

Pour the non-hardened filler obtained by the above composition to a thickness of 40 mm on the upper part of the structure A slab, and a foamed resin buffer material (density 15 kg/㎥ or more, dynamic modulus of 24.2 MN/㎡ or less) on the top of the non-hardening filler, a cushioning material with a thickness of 30 mm is laid A heating spacer was laid on the cushioning material, 40 mm of heating mortar was poured, and after 28 days had elapsed, a 23 kg rubber mallet was installed and measured by falling. (See FIG. 11)

Here, the sound level meter was measured using a sound level meter with a generally sold frequency of 31.5HZ to 8KHZ, and the measurement result was an average of 51dB.

In addition, structure B is a conventional ondol floor structure. In other words, on the structure slab, 30mm of the same cushioning material as A is laid, and on the upper part of the cushioning material, 0.5 pieces of foamed concrete (apparent specific gravity 0.03 or more and 0.70 or less) After 28 days, 40mm of foamed concrete with a crushing strength of 1.4MPa is poured and heating mortar is placed on the top of the foamed concrete. After 28 days of pouring 40 mm, noise was measured in the same way as in A above. The result was an average of 69dB.

[Example 2]

An experiment was conducted using an unhardened filler obtained by mixing 24 parts by weight of fine pernickel slag powder, 70 parts by weight of sand, 3 parts by weight of fine limestone powder, and 36 parts by weight of water.

That is, after laying 30 mm of finished material on the upper part of the slab, pouring 40 mm of non-hardening filler, laying hot water spacer on the upper part of the non-hardening filler, pouring heating mortar, and measuring the noise after 28 days, 53 dB was obtained.

After pouring 70 mm of the non-hardening filler on the upper part of the slab of the structure A, laying a heating spacer, and pouring 40 mm of heating mortar, after 28 days, the noise was measured in the same manner as above, and 50 dB was measured.

As such, it is determined that the non-hardening filler according to the present invention absorbs vibration and noise.

In addition, using a cushioning material and a non-hardening filler, the glass structure was manufactured in a double-layered form with a height of 170mm in width and length of 170mm and a height of 300mm in a square shape. As a result of measuring noise by placing the and non-hardened fillers respectively, 96 dB was measured for the cushioning material and 39 dB was measured for the non-hardened filler (see Fig. 12).

In addition, as a result of placing a cup of water on the cushioning material and the non-hardened filler, the water vibrated violently in the cushioning material, but the unhardened filler hardly shook. was expected to be significantly reduced.

As mentioned above, the present invention has been described in detail with reference to the drawings, but it is clear that the embodiments mentioned in the process are merely exemplary and not limiting, and the present invention is the scope of the present invention provided by the following claims. Within the scope that does not depart from the technical spirit or field, component changes to a degree that can be equally dealt with will fall within the scope of the present invention.
