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

In general, in the case of apartment houses or multi-story buildings, most of the air propagation sound is blocked by the concrete slab structure, but when shock or vibration is directly applied to the floor by people walking or falling objects on the upper floor, solid propagation sound It has the characteristic of being radiated to the lower floors or adjacent households through floor slabs, ceilings and walls without being almost attenuated.

This floor impact sound is a lightweight impact sound that generates a lot of high-frequency sound, such as when a bowl or object is dropped or a chair is moved, and a heavy impact sound that generates a lot of low-frequency sound, such as a child's jumping sound or an adult's walking. are largely separated

On the other hand, in recent years, as multi-story apartment houses such as apartments and villas have become common due to the increase in land prices and the convenience of living, disputes between neighbors due to noise between floors have emerged as a serious social problem.

In order to solve this problem, various technologies have been proposed.

For example, technologies are being developed to absorb noise and vibration generated from the floor by providing a sound insulation panel on the upper part of the slab.

Korean Patent Registration No. 10-1248032 discloses a method for reducing noise between floors by laying a polyethylene foam on the upper surface of a floor slab, stacking a sound absorbing material having a plurality of diaphragm holes at predetermined intervals on the polyethylene foam, and A damper is inserted into the damper hole, a magnesium board is stacked on the sound absorbing material, a cushioning material is laid on the magnesium board, an insulating material is laid on the cushioning material, a pipe panel is stacked on the heat insulating material, and a heat conduction plate is coupled to the pipe panel. In addition, a dry ondol floor having a structure in which a pipe panel is coupled to the heat conduction plate and then a loess board is stacked and stacked thereon is disclosed.

However, in order to reduce inter-floor noise by the prior art, since polyethylene foam, sound absorbing material, damping ball, magnesium board, cushioning material, insulation material, heat conduction plate, and pipe panel must be installed on the top of the floor slab, in order to reduce inter-floor noise As the number of members to be installed increases a lot, there is a problem in that construction costs and material costs for this increase greatly.

As shown in the drawing, the ondol floor structure 10 (hereinafter referred to as 'ondol floor structure' for convenience of description) for reducing inter-floor noise using an uncured filling layer according to the present invention is installed on the slab 100 of the building. As an ondol floor structure 10 for reducing inter-floor noise, the ondol floor structure 10 according to the present invention includes a non-curing filling layer, a sound insulation panel 30, a heating pipe part 40, and a heating mortar layer 50. can be configured to include

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

The non-hardening filling layer 20 may be formed by mixing a lightweight synthetic resin material, a powder member, sand, and water and then stirring them.

Specifically, the powder member, sand and water may be mixed in a weight ratio of 1 to 70:50 to 200:1 to 100, respectively.

The powder member may use one or a mixture of two or more selected from among ferronickel slag, blast furnace slag, copper slag, fine limestone powder, stone powder, and fly ash.

The powder member serves to pressurize the non-hardening filler to the required floor of the building.

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

In addition, in the present invention, the ferronickel slag of the powder member is gradually cooled in the air by water quenched ferronickel slag (granular ferronickel slag) and molten ferronickel slag obtained by quenching molten ferronickel slag using high-pressure water. In the present invention, the hydrogenated quenched ferronickel slag can be used, but it is not limited thereto, and it is also possible to use a mixture of the hydrogenated quenched ferronickel slag and the aggregated ferronickel slag.

In the present invention, as the powder member, not only the ferronickel slag, but also fine powder obtained by miniaturizing industrial by-products such as blast furnace slag, copper slag, fine limestone powder, stone powder, and fly ash may be used. A fine powder may be further included.

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

The non-hardening filling layer is formed by mixing lightweight synthetic resin materials, powder members, sand, and water, and moving and pouring to the slab of a building to be poured through a pump or a special pump vehicle.

At this time, the non-hardening filler for forming the non-hardening filling layer is characterized in that it further includes a lightweight synthetic resin material in addition to the powder member, mori, and water.

In the present invention, the lightweight synthetic resin material is preferably a foamed bead, sculpture or pulverized material of synthetic resin.

Specifically, the synthetic resin may be polystyrene (PS), polyethylene (PE), polypropylene (PP) or ethylene vinyl acetate copolymer resin (EVA).

Specifically, among such lightweight synthetic resin materials, FIG. 14 shows a sculpture of ethylene vinyl acetate copolymer resin (EVA). As shown in FIG. 14, the sculpture of ethylene vinyl acetate copolymer (EVA) can also play a role in protecting the environment and reducing carbon emissions because lightweight scrap pieces (fragments) obtained from waste shoes can be used.

In addition, FIG. 15 specifically shows polystyrene (PS) foam beads among the lightweight synthetic resin materials. As shown in FIG. 15, foam beads of synthetic resins such as PS, PE, and PP may be used as lightweight materials.

A technology in which the foamed beads of the synthetic resin are mixed with aerated concrete in a floor structure for preventing inter-floor noise has been proposed (e.g., Korean Patent Registration No. 10-2107934), but the technology to actually incorporate the foamed concrete into aerated concrete has been proposed. It was difficult to effectively exhibit the noise prevention function, and rather, there was a problem in that the strength of the concrete and other functions were deteriorated.

In the present invention, it is not a technology of mixing the synthetic resin lightweight material into aerated concrete, but a technology of mixing and using it in a non-hardening filling layer.

The synthetic resin lightweight material can be used in high-rise buildings because it does not cause a pressure conveying problem when mixed with a non-hardening filler composed of powder members, sand, and water.

In the present invention, the synthetic resin lightweight material may be included in the range of about 1 to 15 kg with respect to m ³ of the non-hardening filler consisting of powder member, sand and water.

If the amount of the synthetic resin lightweight material is less than 1 kg / m ³ , it is difficult to effectively prevent noise between floors, and if it is more than 15 kg / m ³ , it is preferable to use it within the range.

As described above, when the non-hardening filler composed of the powder member, sand, water, and lightweight synthetic resin material is pressurized and laid, the water gradually evaporates over time, leaving only the powder member, sand, and lightweight synthetic resin material to form a non-hardening filler layer. .

Noise is absorbed (sound absorbed) by the air gap formed between each component of the non-hardening filling layer, that is, the powder member, sand and lightweight synthetic resin materials, and the powder member and sand and lightweight synthetic resin materials, so that the noise is transmitted to the lower floor or to the lower floor. It is possible to prevent noise from being transmitted to the upper floor.

In addition, the powder member component supports a load to improve bearing capacity, and it is possible to reduce a pressing phenomenon caused by a load. That is, by making the particles of fernickel slag, blast furnace slag, copper slag, fine limestone powder, etc. smaller than the particles of sand, it is possible to reduce the voids to improve the bearing capacity and reduce the pressed shape.

The sound insulation panel 30 is disposed above or below the non-curing filling layer 20, that is, between the non-curing filling layer 20 and the slab 100 to absorb noise between floors.

The sound insulation panel 30 is made of a synthetic resin material or a synthetic fiber material to absorb noise between floors, and any material may be used as long as it absorbs noise.

The sound insulation panel 30 is disposed above the non-curing filling layer 20 (FIG. 1), and may be disposed between the non-curing filling layer 20 and the slab 100 (FIG. 6), It is also possible to fix by adhering to the upper or lower side of the non-curing filling layer 20 .

In addition, it is also possible to form the sound insulation panel 30 with a wood wool board having heat resistance.

At this time, the height of the sound insulation panel 30 may be formed smaller than the height of the non-curing filling layer 20 .

The heating pipe part 40 is disposed on the upper side of the sound insulation panel 30 or the upper side of the non-curing filling layer 20 .

The heating pipe part 40 is disposed above the sound insulation panel 30 or the non-curing filling layer 20 to support the pipe line 41 through which hot water is moved and the pipe line 41. It may be made of a heating spacer 80 (in other words, a pipe spacer) for fixing.

The heating spacer may be formed in a panel or mesh structure, and the pipe line 41 is bundled or adhered to the heating spacer by a fixing member 81 to be fixed.

The heating spacer may be made of a plastic material so that the fixing member can be inserted and fixed.

In the present invention, since the non-curing filling layer 20 formed at the bottom of the pipe line does not harden, it is impossible to construct the pipe line without the heating spacer, so it must be provided.

The pipe line 41 is preferably disposed above the heating spacer in a zigzag bent state.

The heating mortar layer 50 is formed on the top of the sound insulation panel 30 so that the heating pipe part 40 is inserted.

The heating mortar layer 50 covers the heating pipe part 40 and applies mortar to the top of the sound insulation panel 30 so that the heating pipe part 40 is inserted into the heating mortar layer 50. can be made

The material of the side cushioning member 60 is formed of a synthetic resin material, and may be formed of, for example, a synthetic resin material having elasticity such as polyethylene (PE) or EVA (Ethylene Vinyl Acetate) resin.

The side buffer member 60 is fixed to the wall 200 before forming the non-curing filling layer 20 on the slab 100, and the lower end is disposed so as to come into contact with the upper edge portion of the slab 100. It can be.

Here, the side buffer member 60 further forms a seating groove on an outer surface in contact with the wall 200 and an inner surface in contact with the heating mortar layer 50, and an elastic buffer made of a synthetic resin material having elasticity in the seating groove. It is preferable to cushion the impact transmitted from the outside by elasticity by fixing the panel, but by disposing a part of the elastic buffer panel to protrude to the outside.

An elastic shock absorber 70 may be further provided on the side shock absorber 60 to absorb external impact and absorb noise.

The elastic buffer means 70 is disposed in the buffer space 71 formed along the longitudinal direction inside the side buffer member 60 and the buffer space 71 of the side buffer member 60, and inside A buffer tube unit 72 made of a synthetic resin material having elasticity filled with air, a support panel 73 made of a metal material disposed inside the buffer tube and attached to both inner surfaces of the buffer tube, and the support panel ( 73) and composed of elastic buffer shafts 74 made of synthetic resin material having elasticity attached or fused to reduce the transmission of noise by the air filled in the buffer tube unit 72 and to reduce the shock absorber. Shock or vibration transmitted from the outside by the tube unit 72 and the elastic buffer shaft 74 can be buffered and reduced.

Here, it is preferable to buffer an external shock or vibration by inserting a pressure coil spring into the elastic buffer shaft 74 so that the pressure coil spring supports the support panel 73 by elasticity.

In addition, it is preferable to further arrange sound-absorbing balls formed with sound-absorbing holes having a penetrating structure inside the buffer tube unit 72 so that generated noise is absorbed by the sound-absorbing holes to reduce noise.

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

[Example 1]

First, the slab structure was made by placing 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 A and B. The slab height was 30 cm from the floor and cured for 28 days. (See Fig. 10)

23 parts by weight of fine powder of fernickel slag, 70 parts by weight of sand, and 3 parts by weight of fine limestone powder were mixed and stirred on the upper part of the structure slab, and mixed with 34 parts by weight of water. As a result of measuring the flow value by mixing at a rate of 5 kg per m ³ of the filler, the flow value was 255 mm as shown in FIG. 11 .

The non-curing filler obtained by the above composition is poured to a thickness of 40 mm on top of the structure A slab, and an EPS buffer material (density 15 kg / ㎥ or more dynamic elastic modulus 24.2 MN / ㎡ or less) on top of the non-hardening filler is laid and a buffer material having a thickness of 30 mm is laid. A heating spacer was laid on the top of the buffer material, a heating mortar was placed at a thickness of 40 mm, and after 28 days, a 23 kg rubber mallet was installed and measured by dropping. (See Fig. 12)

Here, the noise meter was measured using a noise 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, 30mm of the same buffer material as A is laid on the structure slab, 0.5 product of foamed concrete (apparent specific gravity 0.03 or more and 0.70 or less) is placed on top of the buffer material, and 40mm of foamed concrete with an impact strength of 1.4MPa after 28 days is poured, and a heating mortar is placed on top of the foamed concrete. After 28 days of pouring 40mm, the noise was measured in the same way as in A above. The result was an average of 69 dB.

[Example 2]

24 parts by weight of fernickel slag fine powder, 70 parts by weight of sand, 3 parts by weight of fine limestone powder, and 36 parts by weight of water were mixed with PS foam beads at a ratio of 1 kg per m ³ to an experiment.

That is, 30 mm of soft layer material was laid on the top of the slab, 40 mm of non-curing filler was placed, a hot water spacer was laid on top of the non-hardening filler, and a heating mortar was placed. After 28 days, the noise was measured and 53 dB was obtained.

70 mm of the non-curing filler was placed on the top of the slab of structure A, a heating spacer was laid, and 40 mm of heating mortar was placed. 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-curing filler according to the present invention absorbs vibration and noise.

In addition, using a buffer material and a non-hardening filler, a glass structure was made into a double layer with a square shape of 170 mm in width and length and a height of 300 mm. As a result of noise measurement by placing the and non-hardening fillers on each, 96dB was measured for the buffer and 39dB for the non-hardening filler (see Fig. 13).

In addition, as a result of placing a water cup on top of the cushioning material and the non-curing filling material, the water was shaken severely, but the non-hardening filling material was hardly shaken. was predicted to be significantly reduced.

In the 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 only illustrative and not limiting, and the present invention is provided by the claims below.
