Description

Sound-Proof Panel Used Between for Construction}

The present invention relates to an interlayer sound insulation panel for a building, and more particularly, it is installed between floors of a building that is built in a multi-storey building such as a multi-family house or a building to simultaneously sound and sound by circulating and absorbing noises generated from the upper or lower floors. The present invention relates to an interlayer sound insulation panel for building using honeycomb.

In general, human dwelling types are largely classified into single-family homes and apartment houses. More than 50% of the total households in Korea live in multi-family housing such as apartments, and even single-family homes take the form of duplex rather than single floor. In this way, as well as multi-family housing as a single-storey form a multi-storey structure between the floor and the floor is made of a structure in which the walls and floors are mostly made of concrete. However, due to the rigidity of the material, such concrete structures have a rigidity, so that sounds generated from speech, instruments, or devices are delivered to the neighbors by air, resulting in discord between neighbors, and legal disputes between the contractor and the tenant. There was a problem leading up to. In order to solve such a problem, various methods for sound insulation between floors have recently been proposed, and examples of the prior arts include Patent Publication Nos. 10-2005-45164 and Utility Registration Nos. 20-402348.

The noise reduction reducing material for the apartment house noise of Patent Publication No. 10-2005-45164 has a rubber chip layer 1 having a thickness of about 5 mm and a thickness of about 5 mm on the rubber chip layer 1, as shown in FIG. The polyethylene pad layer 2 and the ethylene vinyl acetate chip layer 3 having a thickness of about 10 mm on the polyethylene pad layer 2 are sequentially stacked to form a triple composite structure.

Such a noise reduction abatement material has an excellent absorption rate against noise and excellent thermal insulation performance.

However, such a conventional apartment house noise reduction reducing material has a narrow absorption area of the noise can not completely sound insulation, especially when the thickness is thin, there is a problem that the sound insulation effect is significantly reduced.

In addition, the thermal insulation and sound insulation composite panel of the practical registration No. 20-402348, as shown in Figure 1b, the honeycomb hollow sheet 4 and the honeycomb hollow sheet 4, the honeycomb hollow sheet 4 is formed with several air layers Aluminum reflective sheets (5, 5 ') attached to both sides and formed to reflect heat by a glossy surface, and a fibrous insulation material having a low thermal conductivity and a high sound absorption rate, adhered to the aluminum reflective sheet (5) on one side (6) ) And a calcium silicate board 7 adhered to the lower side of the fibrous insulation 6.

Such a thermal insulation and sound insulation composite panel has excellent heat insulation, insulation, sound absorption and sound insulation by the low thermal conductivity and high sound absorption of the plurality of air layers and the component itself.

However, such a conventional insulation and sound insulation composite panel has a problem that the complete sound absorption and sound insulation is limited because the sound absorption function is simply performed only in each hollow portion of the honeycomb. In addition, the conventional noise reduction materials and composite panels as described above have a problem in that the workability and economical efficiency are deteriorated because the thickness of the conventional noise reduction material and the composite panel must be thickened.

The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a honeycomb having a structure capable of circulating noise and a sound absorbing material having a sound absorbing function, thereby crushing the noise generated in each layer. At the same time, it is possible to completely absorb sound by absorbing sound, and to provide an interlayer sound insulation panel for building which can reduce the overall thickness.

In order to achieve the above object, the interlayer sound insulation panel for building according to the present invention is an interlayer sound insulation panel for preventing the transmission of interlayer noise of a building, and the first sound insulation member for primarily sound insulating noise generated in each floor. And a honeycomb having a plurality of cells formed on one side of one side of the first sound insulation member and formed by a partition wall that is formed repeatedly and repeatedly, and the other side of the honeycomb is attached to one side of the noise. In the building sound insulation panel having a second sound insulating member for sound insulation, the honeycomb is formed of one of non-toxic polyolefin resin, thermoplastic resin and paper; The first sound insulating member, the second sound insulating member, and the honeycomb are attached by a melt adhesive film; The partition wall forming each cell of the honeycomb is provided with a through hole for communicating the cells with each other so as to circulate or guide the noise flowing from the first sound insulation member and the second sound insulation member. Become; Characterized in that the building interlayer sound insulation panel further comprises a sound absorbing material for inserting into some of the cells of the honeycomb to absorb the noise introduced into the cell to absorb.

According to the building insulation sound insulation panel according to the present invention, after the sound insulation is first or third by the sound insulation members of the upper and lower, the noise introduced into each sound insulation member is respectively in the honeycomb therebetween. Through the through-holes formed in the bulkheads of the cells, the cells are circulated or circulated through the cells, and are absorbed and exhausted by the sound absorbing material selectively provided in some cells, so that the upper and lower layers can maintain a mutually comfortable state and also generate complaints. There is an excellent effect that can be completely prevented.

In addition, it is possible to achieve excellent sound insulation and sound-absorbing effect even at a thinner thickness than the conventional sound absorbing or soundproofing material can reduce the thickness of the slab between the layers has the advantage of improving workability and economic efficiency. By circulating the noise generated in each floor while crushing and absorbing at the same time completely soundproof, it is possible to prevent discomfort between neighbors and to maintain a comfortable indoor atmosphere.

It will be described below in detail with reference to the accompanying drawings, the building sound insulation panel according to the invention.

Figure 2 is an exploded perspective view showing the building insulation sound insulation panel according to the first embodiment of the present invention, Figure 3 is a partial cutaway perspective view showing a state in which the components of the sound insulation panel of Figure 2 coupled, Figure 4 is a line of Figure 3 5 is an enlarged cross-sectional view according to IV-IV, FIG. 5 is an enlarged cross-sectional view taken along the line V-V of FIG. 3, and FIGS. 6 to 10 are various embodiments of through holes formed in the honeycomb applied to the building sound insulation panel according to the present invention. 11 and 12 are cross-sectional views similar to FIGS. 4 and 5 showing sound absorbing states, which are indicated by arrows, showing a state of circulation and attenuation of noise in a sound insulating panel according to a preferred embodiment of the present invention.

First, referring to FIGS. 2 to 5 and FIGS. 11 and 12, in an interlayer sound insulation panel for building according to a preferred embodiment of the present invention, reference numeral 10 denotes a first sound insulation member, which primarily blocks noise generated in a floor. It plays a role.

The first sound insulation member 10 is formed of a plate material having excellent sound insulation, as well as excellent workability and processability, light weight and heat insulation. As an example of such a board | plate material, a galvanized steel plate, a metal plate, an aluminum steel plate, a PVC plate, a steel plate, an aluminum steel plate, a stainless steel plate, etc., and an aluminum steel plate is preferable here. Of course, the thickness and size may be set in various ways depending on the intended use and the manufacturer amount.

On the other hand, one surface of the first sound insulating member 10 is attached by an adhesive or a melt adhesive film 12 so that the honeycomb described later can be attached. The molten adhesive film 12 is formed of a metal-friendly polyolefin resin or thermoplastic resin film, when the heat is applied during the attachment process of the first sound insulating member 10 and the honeycomb described later the molten adhesive film 12 The carboxyl groups are attached to the surface of the first sound insulating member 10 and are bonded to each other.

The honeycomb 20 is formed of a polymer non-toxic polyolefin-based resin, a thermoplastic resin or papermaking, and a rectangular, pentagonal, or hexagonal cell 22 having a predetermined height is continuously and repeatedly arranged to form a honeycomb structure. In addition, the volume ratio of space to resin in the honeycomb 20 is set to 95 to 97: 5 to 3.

In particular, the through-hole 26 is formed in the partition wall 24 forming each cell 22 of the honeycomb 20 so that air or noise can pass therethrough. Each of the through holes 26 communicates with the internal spaces of the respective cells 22, thereby allowing each of the honeycombs 20 to pass through the first sound insulating member 10 or the second sound insulating member to be described later. The noise flowing into the cell 22 is circulated to each cell 22 and is crushed and absorbed to disappear.

In particular, the partition wall 24a of one of the partition walls 24 facing each other among the partition walls 24 forming the respective cells 22 in order to increase the circulation path of the noise and ultimately increase the damping rate and the sound absorption rate of the noise. It is preferable to form a through hole 26 in the upper part, and a through hole 26 in the lower part of the other partition wall 24b. As the circulation path of the noise is lengthened by the position of the through holes 26, the rate of damping of the noise can be improved.

The through holes 26 may be formed in various partitions 24 according to the size or use of the sound insulation panel.

That is, when the height or thickness of the honeycomb 20 is low, the through hole 26a is formed only in the upper portion of each of the partition walls 24 (FIG. 6), or in the lower portion of the partition walls 24. Only through holes 26b can be formed (Fig. 7). When the honeycomb 20 has a high height, through holes 26c may be formed in both upper and lower portions of the partition walls 24 (FIG. 8). Alternatively, a relatively small or fine through hole 26d may be perforated throughout the respective partition walls 24 (FIG. 9), or a circular through hole in a generally central portion of the respective partition walls 24. It is possible to form by drilling 26e (Fig. 10).

In addition, with respect to each of the partitions 26, the area ratio of the through holes 26; 26a to 26e formed in the partitions is 9: 1 to 7: 1. Here, if the area ratio is set to 9: 1 or less, the noise circulation and noise suppression rate may be reduced due to narrow circulation passages of noise, whereas if the ratio is set to 7: 1 or more, the sound absorption rate and noise suppression rate may be increased, but Strength may be lowered.

Reference numeral 30 is a sound absorbing member inserted into each cell 24 of the honeycomb 20. The sound absorbing member 30 serves to absorb and crush the noise circulating through the respective through holes 28 and the cells 24 of the honeycomb 20.

The sound absorbing member 30 may be inserted into or mixed with each cell 24 of the honeycomb 20 in various ways. In particular, the sound absorbing material 30, each cell formed in the honeycomb 20, so as to be continuously absorbed by the sound absorbing material 30 while circulating the noise introduced into the honeycomb 20 continuously and repeatedly. Inserted alternately or repeatedly in zigzag fashion at 24.

In addition, the sound absorbing material 30 is formed of a material such as polyether-based nonwoven fabric, resin felt, urethane foam, polyethylene felt, recycled fiber felt and the like with excellent sound absorption. Of course, the sound absorbing material 30 is installed to be inserted independently into each of the corresponding cells 24, or each of the sound absorbing material 30 to be inserted into the corresponding cell 24, a plurality of sound absorbing material 30 May be continuously formed and inserted into and installed in the corresponding respective cells 24 at the same time.

Reference numeral 40 is a second sound insulation member facing the first sound insulation member 10 and shielding the other side of the honeycomb 20. The second sound insulation member 40 is formed similarly to the first sound insulation member 10.

That is, the second sound insulation member 40 is formed of a plate material which is excellent in sound insulation as well as excellent workability and workability, light weight and heat insulation. Examples of such a plate material include a galvanized steel sheet, a metal sheet, an aluminum steel sheet, a PVC sheet, a steel sheet, an aluminum steel sheet, a stainless steel sheet, and the like, and an aluminum steel sheet having the best workability, light weight, and heat insulating property is most preferred. Of course, the thickness and size may be set in various ways depending on the intended use and the manufacturer amount.

In addition, the second sound insulating member 40 is attached by a melt adhesive film 42. The molten adhesive film 42 is formed of a metal affinity polyolefin resin or thermoplastic resin film, such as the molten adhesive film 22 applied to the first sound insulating member 10, the second sound insulating member 40 When the heat is applied during the attachment process of the honeycomb 20 and the carboxyl group of the molten adhesive film 42 is attached to the surface of the second sound insulating member 40 is bonded to each other.

Hereinafter, the installation method and the operation mode of the building interlayer sound insulation panel configured as described above will be described in detail with reference to FIGS. 11 and 12.

For example, the worker repeatedly installs the sound insulation panel according to the present invention throughout the entire floor of a building such as an apartment. As such, the noise and the impact sound generated in the upper layer, for example, in the state interposed between the layers, are primarily sound insulating by the first sound insulating member 10.

Subsequently, in the case of the occurrence of continuous repetitive noise or strong noise, some of the noise is blocked by the first sound insulating member 10, while some of the noise passes through the first sound insulating member 10 to pass the honey. Into each cell 22 of the comb 20.

As described above, some of the noise introduced into the cells of the honeycomb 20 is absorbed by the sound absorbing material 30 installed in some of the respective cells 22, and the sound absorbing material 30 is not absorbed by the sound absorbing material 30. Noise is diffused to the surroundings or reflected by the second sound insulating member 40, and some of the noise introduced into the cell 22 in the empty space is caused by its own diffusion or by the respective partition walls 24. It spreads around by reflections.

At this time, the diffused and echoed noise as described above is circulated by the through-holes 26 formed in each of the partitions 24 or exhausted or crushed while being circulated, and at the same time provided in some of the cells 22. The sound absorbing material is absorbed by the sound absorbing material 30 and is sound insulating.

Of course, when some of the noise has a strong frequency, the noise of the part that is not completely exhausted and absorbed in each cell 22 and the sound absorbing material 30 of the honeycomb 20 is the second sound insulation panel 40 Blocked by to achieve a complete sound.

In the above description, the case in which the noise is generated in the upper layer has been described. However, in the case where the noise is generated in the lower layer, the noise is circulated and absorbed in the reverse order as described above.

In addition, in the above description, the noise is circulated and guided in a preferred embodiment of the present invention, that is, the through hole 26 is zigzag or staggered up and down in each partition 24 of the honeycomb 20. Although described above, even when the through-holes 26a to 26e of various shapes as shown in FIGS. 6 to 10 are formed in the partition 24, the noise is circulated and absorbed in the same operation mode to be blocked.
