Description

Noise Preventing Assembling structure for Inter layer Noiseproofing

The present invention relates to a noise prevention assembly for preventing the noise between floors in an assembly building such as an apartment or a multi-unit house. In particular, the noise between floors can be effectively prevented through the air layer formed by stacking a plurality of soundproof members having protrusions. A noise suppression assembly for isolation.

In an assembly building such as an apartment, residents suffer from noise generated between the lower floor and the upper floor. These noises are generated when a person living upstairs drops a heavy object onto the floor or moves a piece of furniture, etc., or when a heavy object falls on the floor or a child who lives in the floor runs badly. It is also classified as a heavy impact sound.

However, since the degree of inconvenience caused by noise depends on the subjective feeling of the resident, any noise can cause inconvenience to the resident, and in serious cases, it can also cause legal disputes between residents. Therefore, a technique for blocking the noise between floors of the aggregate has been proposed.

In general, the conventional technology of preventing noise between floors, for example, an apartment, is a concrete floor structure on a slab, a soundproof pad such as styrofoam is applied to the lightweight foam concrete is poured. On the light-bubble concrete, hot water pipes for heating are installed, and mortar is poured over the hot water pipes to cure, and then a floor covering is attached.

According to the conventional technology, since the styrofoam is formed with a large area corresponding to the floor area, noise generated between layers cannot be sufficiently absorbed through the styrofoam, and the styrofoam acts as a kind of diaphragm, causing vibrations having a long amplitude and long duration. As a result, there is a problem that noise blocking is not good. In addition, the noise blocking effect is further reduced for the heavy impact sound.

The present invention has been made in view of the above point, and an object of the present invention is to provide a noise preventing assembly for interlayer noise blocking which can effectively block interlayer noise through an air layer formed by cross-laminating soundproof members having protrusions of a predetermined thickness. .

The above objects, features and other advantages of the present invention will become more apparent by describing the preferred embodiments of the present invention in detail with reference to the accompanying drawings. Hereinafter, with reference to the accompanying drawings will be described in detail the noise prevention assembly according to an embodiment of the present invention.

1 is a perspective view in one direction of the noise prevention assembly according to an embodiment of the present invention, FIG. 2 is a perspective view for describing in detail the shape of the soundproof member in FIG. 1, and FIG. 3 is an AA line in FIG. 4 is a cross-sectional view taken along the line BB of FIG.

Hereinafter, the structure of the noise suppression assembly according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4.

The noise prevention assembly may be used as an interlayer noise barrier of the assembly and may be utilized as a noise barrier for a floor or sidewall. The noise prevention assembly includes a plurality of soundproof members 110 stacked up and down, an intermediate member 150 interposed between the soundproof members 110, and a soundproof member 140 positioned at the top of the soundproofing members 110. The soundproof cover plate 160 disposed on the top is made of a stacked structure in order.

The soundproofing members 110 may include a first soundproofing member 120 disposed below and a second soundproofing member 140 disposed above the first soundproofing member 120. The soundproofing members 110 have protrusions 122 and 142 having a predetermined thickness on one surface thereof, and air layers 124 and 144 are formed between the protrusions 122 and 142. The protrusions 122 and 142 may extend in a straight line along both ends of the sound insulation members 120 and 140. The spacing between the protrusions 122 and 142 may be maintained in various ways for effective noise suppression. For example, the width 122a of the protrusion and the width 124a of the air layer may be designed to be the same.

The protrusions 122 and 142 are depicted in the cross section of a rectangular shape in the embodiment of the present invention, but may also be made in the shape of a circle, oval or polygon.

The soundproof members 110 may be disposed such that the protrusions 122 and 142 cross each other. The first protrusion 122 formed on the first soundproofing member 120 and the second protrusion 142 formed on the second soundproofing member 140 are disposed in directions perpendicular to each other, such that the first protrusion 122 is formed of the second protrusion. The structure may be formed so as to lie in the direction crossing 142. Protrusions 122 and 142 are arranged in a direction facing each other. That is, the first protrusion 122 is formed to face the top surface, and the second protrusion 142 is formed to face the bottom surface. Here, the lower surface or the lower side means the bottom surface when the noise prevention assembly is embedded, and the upper surface means the opposite surface of the lower surface.

When the sound insulation members 120 and 140 are stacked, naturally sealed air layers 124 and 144 are formed. The air layers 124 and 144 properly cancel out the vibration sounds transmitted through the sound insulation members 120 and 140, thereby effectively blocking the fine noises that cause interlayer noise.

Preferably, the material of the sound insulation members 110 and the size defined by the width b and the length c are the same. However, each thickness may be different. The sound insulation members 110 may be manufactured using materials such as foamed styrofoam, polyethylene (PE), polypropylene (PP), and polyurethane (PU).

As described above, it can be said that the arrangement of the protrusions in the direction perpendicular to each other is stable in the structure of the noise suppression assembly, but the protrusions are parallel to each other and inclined in consideration of the necessity in the manufacturing process and the noise state at the installation site. It can also be arranged in the direction.

The intermediate member 150 may be additionally added for the noise blocking effect, and preferably has the same width b and length c as the first soundproofing member 120 and the second soundproofing member 140. Similarly, the sound insulation cover 160 may be additionally added to the upper portion of the second sound insulation member 140 for the noise blocking effect, and serves to structurally support the load of the foundation concrete to be applied on the intermediate member 150 in the future. Sometimes. The soundproof cover plate 160 also preferably has the same width b and length c as the intermediate member 150.

Since the intermediate member 150 and the soundproof cover plate 160 may be provided with a relatively thin thickness than the soundproof members 110, the intermediate member 150 and the soundproof cover plate 160 may be formed of a rigid material. In order to maintain the above function, the intermediate member 150 and the soundproof cover plate 160 may be manufactured using materials such as polyvinyl chloride (PVC), polyethylene (PE), and polypropylene (PP).

When the noise suppression assembly is applied to an assembly building, it may be buried in various thicknesses. For example, the total height a of the structure of the noise suppression assembly may be set to 30 mm.

First, the total height of the first soundproofing member 120 may be 13 mm including the height of the first protrusion 122 in the first soundproofing member 120 in contact with the bottom surface of the collective building. In the second soundproofing member 140 positioned above the first soundproofing member 120, the total height of the second soundproofing member 140 may be 16mm including the height of the second protrusion 142. In addition, since the intermediate member 150 and the soundproof cover 160 may each have a thickness of 0.5 mm, the overall height is maintained at 30 mm. As described above, when the heights of the protrusions 122 and 142 are set to 6 mm, the heights of the air layers 124 and 144 are naturally set to 6 mm. Therefore, the noise prevention assembly is provided as an integrated standard product and thus can be utilized as a reference value in the design of the building inner wall.
