Today, unlike the past, most of the common housing is shared by several households that are independent of each other in a single building. Apartment houses may include apartments, townhouses and multi-family homes.

As apartments grew in shape, it became common for different households to tackle a wall and live close together. Since the upper and lower houses share floors and ceilings, the inter-level noise dispute between the upper house, which is inevitably sounding, and the lower house, which is inevitably heard, becomes a big issue.

Floor noise is noise pollution and, like other noise pollution, has adverse effects on the mental and physical health of residents. The Noise and Vibration Control Act and the Housing Act define noise generated by running or walking motion (direct impact noise), noise generated by the use of televisions, sound equipment, etc. as the range of interlayer noise.

In general, the interlayer floor structure of a multi-family house forms a light-bubble concrete layer on the basis of the concrete slab floor surface, a heating piping and finishing mortar layer thereon, PVC flooring, wood flooring, reinforced floor, and porcelain tile. , Floor coverings such as plywood floor, polishing tile, steel floor, and marble tile.

In the conventional interlayer floor structure, the lightweight foam concrete layer formed on the top of the concrete slab is responsible for attenuating the noise. However, in the case of the direct impact noise generated by the direct impact on the concrete slab floor, it is not absorbed or blocked properly. I can't do it. In other words, the noise and vibration between the floor caused by the impact directly applied to the floor by the children running around is transmitted to the lower floor directly, there is a problem that gives discomfort to the residents of the lower house.

In this regard, Korean Patent Publication No. 10-1546896 discloses an interlayer noise prevention floor support using a vacuum layer to reduce the generation of interlayer noise by blocking the propagation path of the floor impact sound transmitted to the lower layer using the vacuum layer. have.

However, a plurality of cylindrical vacuum layers are formed on the bottom support, and the support plates and the supporting legs of the piston and the cylinder structure are installed for each vacuum layer, and the structure is not only complicated, but the piston must be accurately positioned in the vacuum layer during construction. Therefore, there is a problem that construction is complicated and difficult.

On the other hand, attempts to recycle waste resources in the manufacture of such an interlayer noise preventing floor support have been made in many aspects. For example, waste PET bottles can be recycled as waste resources.

However, unlike transparent PET bottles, colored PET bottles are extremely limited in recycling, so they are sorted, crushed, dehydrated and dried. There is a very falling problem.

1, 3, and 4, the illustration of the microhole 410 is omitted.

The lower buffer 100 is a foamed rubber formed in a rectangular plate shape. The lower cushioning material 100 is located at the top of the concrete slab 10. The lower cushioning material 100 serves to block and absorb physical shocks, vibrations, and noises transmitted from the floor finishing material 40 and the floor slab 20.

The lower buffer 100 is formed of EVA (Ethylene-Vinyl Acetate) material. EVA is an ethylene vinyl acetate copolymer and is a polymer obtained by copolymerizing ethylene and a vinyl acetate monomer. EVA increases density with increasing vinyl acetate content, but decreases crystallinity and increases flexibility. Lower buffer 100 is formed of EVA, thereby having flexibility, impact resistance, self-adhesiveness and heat resistance. In this case, the lower buffer 100 may be used in place of EVA (Expanded Polystyrene), XPS (Extruded Polystylene), EPP (Expanded Polypropylene) is substituted.

On the lower surface of the lower buffer 100, the support protrusion 110 and the support groove 120 is formed in a grid pattern pattern over the entire area. At this time, the support protrusion 110 and the support groove 120 is formed while alternating with each other at the same horizontal and vertical intervals. In addition, the support protrusion 110 is a trapezoidal shape inverted in cross section as shown in Figure 2, the support groove 120 is formed in a trapezoidal shape when viewed from the front. The bottom surface of the support protrusion 110 is in close contact with the upper surface of the concrete slab 10.

Since the support protrusion 110 and the support groove 120 alternately take a continuous structure, when the physical shock transmitted from the floor finishing material 40 is applied, the physical protrusion absorbs the physical shock while compressing and stretching.

That is, when an impact is applied to the lower cushioning material 100, the support groove 120 is contracted toward the large concrete slab 10 and the impact applied while returning to the original shape is dispersed.

On the other hand, the lower buffer 100 is the upper intaglio groove 130 is dug over the entire area of the upper surface. At this time, the upper intaglio groove 130 is dug to form a negative pattern of the lattice pattern. The lower indentation groove 130 is seated on the lower side of the noise preventing material 200 to be described later.

The upper intaglio groove 130 is the upper sphere groove 132 and the upper connection groove 134 is dug in the shape of the vacuum port 210 and the vacuum tube 220 of the noise suppression material 200. The lower side of the vacuum sphere 210 of the noise suppression material 200 is seated in the upper opening 132, the lower side of the vacuum tube 220 is seated in the upper connection groove 134.

At this time, the upper spherical groove 132 is arranged in a row and a column so that the plurality is spaced at equal intervals in a semicircular shape so that the entire shape is formed in a rectangular shape. The upper connection groove 134 is dug to form a semi-cylindrical shape to communicate with the center between the upper sphere groove 132. The upper connection groove 134 connects the upper sphere groove 132 with each other. At this time, the upper spherical groove 132 and the upper connection groove 134 is integrally dug to form a negative pattern of the lattice pattern.

 In other words, the upper connection grooves 132 are connected to each other by the upper connection grooves 132 in a state in which the upper hole grooves 132 are spaced apart from each other vertically and horizontally.

Noise suppression material 200 is located between the lower buffer 100 and the upper buffer 300 to be described later, through the bottom slab 20 and the floor finishing material 40 It blocks and absorbs shocks, noises and vibrations transmitted directly or indirectly. At this time, the noise preventing material 200 is made by recycling waste PET bottles.

The noise suppression material 200 is made by sealing the inside after vacuuming the inside after inserting the PET flake raw material made through the process of collecting, compressing, crushing, washing, drying and separating metal from the waste PET bottle into a mold injection machine. At this time, the PET bottle can be used irrespective of the distinction between transparent PET bottles and colored PET bottles. In the case of colored PET bottles, recycling is extremely limited, so the recycling rate is very low, and thus, the noise reduction material 200 is used to solve this problem.

The noise preventing material 200 serves to block the progress of the noise transmitted between the lower buffer 100 and the upper buffer 300. The noise preventing material 200 is integrally formed with the vacuum port 210, the vacuum tube 220 and the connecting plate 230.

The vacuum holes 210 are arranged in rows and columns spaced apart from each other horizontally and vertically in a spherical shape formed inside the hollow shape to form a rectangular shape. The vacuum tube 220 connects the centers of the vacuum holes 210 facing each other in a cylindrical shape formed in a hollow shape so as to communicate with each other. The connecting plate 230 connects the side surfaces of the vacuum port 210 and the vacuum tube 220 to communicate with each other while blocking the inner space of the vacuum tube 220 in a pair of spaced plate shapes. At this time, the vacuum port 210, the vacuum tube 220 and the connecting plate 230 is formed in a vacuum state without air inside.

As described above, the noise suppression material 200 is integrally injected with the vacuum port 210, the vacuum tube 220, and the connecting plate 230 into a PET flake made of a waste PET bottle, and is sealed after making the interior into a vacuum state. Accordingly, the interior of the noise prevention material 200 is in a vacuum state, thereby blocking the transmission of sound and vibration. That is, since there is no medium for transmitting sound and vibration in the interior of the noise suppression material 200, the progress of sound and vibration is blocked.

On the other hand, the horizontal and vertical size of the noise suppression material 200 is formed to be the same as the size of the lower buffer 100 and the upper buffer 300.

Further, the lower side of the noise suppression material 200 is seated in the upper intaglio groove 130 of the lower buffer 100, the upper side is seated in the lower intaglio groove 310 of the upper buffer 300 to be described later. At this time, the noise preventing material 200, the lower buffer 100 and the upper buffer 300 may be applied by applying an adhesive, or may be combined in a forced fit method.

The lower portion of the vacuum hole 210 and the lower portion of the vacuum tube 220 positioned on the lower side of the noise suppression material 200 are seated to be in close contact with the upper hole groove 132 and the upper connection groove 134 of the lower buffer material 100, respectively. The upper portion of the vacuum hole 210 and the upper portion of the vacuum tube 220 located on the upper side of the noise suppression material 200 are seated to be in close contact with the lower spherical groove 312 and the lower connection groove 314 of the upper buffer 300, respectively. As a result, the noise preventing material 200 is positioned between the lower buffer 100 and the upper buffer 300.

 On the other hand, the upper and lower portions of the vacuum tube 220 and the connecting plate 230, the cross support 240 is formed to protrude outward so as to connect between the vacuum port 210. The cross support 240 is formed to have a grid pattern that is connected to each other.

Cross support 240 serves to increase the bending strength so that the shape is not distorted during vacuum molding by injecting the pet flake material into the noise prevention material 200. That is, when the noise suppressing material 200 is injected into the pet flake raw material, a separate protrusion is provided to extract air to form a vacuum, and the cross support 240 prevents the shape from being twisted. In addition, the cross support 240 prevents the shape of the noise suppression material 200 from being deformed by external force during construction of the interlayer noise blocking structure of the present invention.

The upper buffer 300 is formed in a rectangular plate shape. The upper buffer 300 is located between the upper portion of the noise suppression material 200 and the lower portion of the bottom slab 20. The upper buffer 300 serves to absorb and block the physical shock and vibration and noise transmitted from the floor finishing material 40 and the floor slab 20.

The upper buffer 300 is formed of EPS (Expanded Polystyrene) material. EPS is a polystyrene expanded by the action of a blowing agent, and is light, and excellent in water resistance, insulation, sound insulation, buffering properties, and the like. The upper buffer 300 may be used by replacing extruded polystylene (XPS), ethylene vinyl acetate (EVA), expanded polypropylene (EPP), or the like instead of EPS.

In addition, the upper buffer 300 serves to insulate the warm water of the hot water passing through the hot water pipe 30 built in the bottom slab 20 to the lower side. In addition, the bottom slab 20 is also blocked to prevent the rise of cold air to the side.

The lower intaglio groove 310 is dug over the entire area of the lower surface of the upper buffer 300. At this time, the lower intaglio groove 310 is dug to form an intaglio pattern of lattice pattern. An upper side of the noise suppression material 200 is seated in the lower intaglio 310.

The lower intaglio groove 310 is provided with the lower sphere groove 312 and the lower connection groove 314 in the shape of the vacuum hole 210 and the vacuum tube 220 of the noise suppression material 200. The upper side of the vacuum port 210 of the noise suppression material 200 is seated in the lower sphere groove 312, the upper side of the vacuum tube 220 is to be seated in the lower connection groove 314.

At this time, the lower spherical groove 312 is arranged in a row and a column so that the plurality is spaced at equal intervals in a semicircular shape so that the entire shape is formed in a rectangular shape. The lower connection groove 314 is dug so as to communicate with each other in the center between the lower sphere groove 312 in a semi-cylindrical shape. The lower connection groove 314 connects the lower sphere grooves 312 with each other. At this time, the lower sphere groove 312 and the lower connection groove 314 is integrally dug to form a negative pattern of the lattice pattern.

In other words, the lower spherical grooves 312 are connected to each other by the lower connection grooves 314 in a state where the lower spherical grooves 312 are spaced apart from each other vertically and horizontally.

In addition, the sound absorbing plate 400 to be described later is located in close contact with the upper surface of the upper buffer 300.

Sound absorbing plate 400 is located in close contact with the upper surface of the upper buffer 300 in a thin plate shape. In this case, an adhesive may be applied to the lower surface of the sound absorbing plate 400 and the upper surface of the upper buffer 300.

Sound absorbing plate 400 is formed of an aluminum material serves to increase the strength of the upper buffer 300. That is, since the upper buffer 300 is formed of a structurally soft material, the sound absorbing plate 400 serves to protect the shape from being deformed in the upper portion of the upper buffer 300.

On the other hand, the sound absorbing plate 400 is formed with a micro hole 410 which is a fine hole over the entire area. The microhole 410 serves to absorb the noise transmitted from the bottom finish material 40 and the bottom slab 20. So the noise is to proceed to the upper buffer 300 in a state in which a portion of the sound absorbing plate 400 is absorbed.

The upper intaglio groove 130 formed on the upper portion of the lower buffer 100 is in close contact with the vacuum port 210 and the vacuum tube 220 formed on the lower side of the noise suppression material 200. At this time, the cross support 240 is inserted into the lower cushioning material 100. At this time, when placing the noise suppression material 200 on the upper portion of the lower buffer 100, it is not necessary to finely adjust the exact position, if only the approximate position of the vacuum hole located on the lower side of the noise suppression material 200 ( 210 and the vacuum tube 220 is naturally in close contact with the upper sphere groove 132 and the upper connection groove 134.

And the upper cushioning material 300 covers the upper side of the noise suppression material 200. The vacuum port 210 and the vacuum tube 220 formed on the upper side of the noise suppression material 200 are in close contact with the lower intaglio groove 310 formed in the lower portion of the upper buffer 300. At this time, the lower portion of the upper buffer member 300 in the vacuum hole 210 and the vacuum tube 220 located on the upper side of the noise suppression material 200 in the state of only adjusting the approximate outer position to the noise suppression material 200. 312) and the lower connection groove 314 is in close contact naturally. At this time, the cross support 240 formed on the upper side of the vacuum tube 220 and the connecting plate 230 is inserted into the upper buffer 300. Accordingly, as described above, the cross support 240 also serves to fix the lower buffer 100 and the upper buffer 300.

Since the sound absorbing plate 400 is covered, the construction time is shortened, and construction also has the advantage of being easy. In addition, by arranging the plurality of lower shock absorbers 100, the noise preventer 200, the upper shock absorbers 300, and the sound absorbing plate 400 in a modular manner, the construction can be made in accordance with the area of the concrete slab 10. have.

After that, the noise and vibration reaches the upper shock absorber 300, and at this time, some of the noise and vibration are absorbed.

Again, the noise and vibration continues down to reach the soundproofing material 200. Since the inside of the noise prevention material 200 is connected to the vacuum port 210, the vacuum tube 220 and the connecting plate 230 to be in a vacuum state, there is no medium for transmitting noise itself. The noise no longer proceeds and is blocked. At this time, some noise may move toward the lower buffer material 100 through the material itself of the noise suppression material 200. In addition, the remaining vibration is also moved toward the lower buffer 100. At this time, the lower buffer 100 is to absorb the remaining noise and vibration once again.
