Description

DOUBLE SANDWICH PANEL FOR USE OF SOUND ABSORBING}

The present invention relates to a double sandwich sound absorbing panel for building use for building walls, partitions, ceilings, roofs, and in particular, the sound absorbing structure and the heat insulating material is installed at the same time between the table, the back steel sheet, the noise inside the resonance sound absorbing panel of the structure The present invention relates to a double sandwich sound absorbing panel for building, which can be absorbed by resonating and dissipating sound energy along a passage.

Conventionally, in the sandwich sound absorbing panel for construction as shown in FIG. 1A of the accompanying drawings, a filler for sound absorption and heat insulation is attached between two layers of printed steel sheets forming the outer surface of the sandwich panel, and another inside of the filler is provided. The plate is interposed, the double sandwich sound-absorbing panel for building, characterized in that the perforated sound waves through a predetermined pattern on one side of the outer printed steel sheet has been registered with the Korean Intellectual Property Office (see Utility Model Registration No. 20-0359035).

However, the conventional double sandwich sound-absorbing panel for building has low sound absorbing effect of the sound absorbing and insulating material, and noise is easy to move to other spaces, resulting in poor sound insulation and sound absorbing, as well as high density of sound absorbing and heat insulating material. There is a problem in that the sound insulation and sound-absorbing property is high and hard to be easily transmitted to other spaces.

On the other hand, the interior finishing material panel that finishes the interior by installing on the ceiling or wall of the room is the internal finishing material panel.In the case of the building under Article 61 of the Enforcement Decree of the current building law, almost all interior finishing materials are non-combustible, semi-non-combustible, and flame-retardant materials. It is restricted to use only when it passes KS F 2271, a flame retardant test method for building materials and structures of buildings.

Among the panels, a flame retardant material is disclosed in the insulation sound absorbing panel of the Korean Utility Model Registration No. 20-0295625 shown in FIG. 1B of the accompanying drawings, in which at least one plate-like surface material layer is formed and formed on the surface material layer. Sound absorbing material layer composed of a mixture of a fiber material and a flame retardant material is laminated. The fiber material was a fiber comprising any one synthetic resin selected from the group consisting of polyester resins, polypropylene resins, polyethylene resins, composite polypropylene resins and composite polyethylene resins. In the thermal insulation sound absorbing panel according to the above-mentioned registered utility model, the sound absorbing layer laminated on the surface layer is made of synthetic resin fiber, which has a low degree of absorbing sound, and thus there is a problem in that the sound absorbing layer is not properly absorbed. Since it can be expected to be properly flame retardant according to the application material of the surface layer and easy to be a panel of the weight, there was a problem that the construction is difficult if it is a panel of the weight.

In addition, unlike the above-described registered utility model, and further improved the flame retardant function, as shown in Figure 1c non-bearing wall having a fire-resistant performance is published in Korean Patent Laid-Open Publication No. 2003-0035281, which is flame retardant It is composed of a set of fireproof panels made of a single plate made of a material having a waterproof and fireproof function, and a urethane foam having a heat insulating and flame retardant function between the set of fireproof panels. The Patent Publication discloses that the fireproof panel on the outer surface and the urethane foam therein have a heat insulation and flame retardant function, so that a proper flame retardant effect can be obtained. However, since the fireproof panel uses heavy materials made of phosphoric acid and aluminum sulfate, the panel itself is It included the problem that it had to be heavy. All the above panels have a problem that the outer surface material layer or the fireproof panel is made of a brittle material such as gypsum, MDF, etc., so that the edges of each side are easily broken, thereby lowering the product value.

The present invention has been invented to solve the above problems, by combining the insulation and the resonance sound absorbing panel between the table, the back steel sheet, the sound absorption is improved compared to the existing double sandwich sound absorbing panel using the conventional single and composite materials The object is to provide a double sandwich sound absorbing panel for construction.

In addition, the resonance absorbing panel and the insulation are installed at the same time between the table and the back steel sheet, and the sound absorbing panel is formed inside the resonance absorbing panel so that the noise generated from one side of the panel or on one side of the panel is passed through the acoustic wave through the surface steel sheet. It is an object of the present invention to provide a double sandwich sound absorbing panel for building which can be significantly improved sound insulation and sound absorbing effect by being exhausted along the first sound absorbing space and the second sound absorbing space of the sound absorbing panel.

Sandwich sound-absorbing panel of the present invention for solving the technical problem as described above,

Rear steel sheet; A surface steel sheet which is provided to face the rear steel sheet and is provided with a plurality of sound wave through holes; The table, the insulating material is filled between the back steel sheet; Resonance is installed between the surface steel sheet and the heat insulating material, and the sound wave passing through the plurality of sound wave through holes formed in the surface steel sheet is blocked by the cover member of the sound absorbing material so as to absorb the resonance and the plurality of second sound-absorbing spaces are formed As a sandwich sandwich sound absorbing panel for building comprising a sound absorbing member,

In particular, the resonance sound absorbing member is preferably to form a sound absorbing induction hole.

The above-described double sandwich sound absorbing panel for building of the present invention forms a resonance sound absorbing member between the table and the back steel sheet, and combines the resonance sound absorbing structure with the first sound absorbing space and the second sound absorbing space to exhaust the noise. It has the effect of providing better sound absorption than the building double sandwich sound absorbing panel using the material.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

2A to 2D are perspective views and exploded perspective views according to embodiments of various surface plates of the sandwich sound absorbing panel for building the present invention.

Sandwich sound absorption panel for building the invention according to the drawings,

It is provided between the rear steel sheet 10 and the rear steel sheet 10, and is provided between the surface steel plate 11 and the surface, the rear steel plates 10 and 11, which are provided with a plurality of sound wave through holes 12. Is installed between the heat insulating material 20, the surface steel plate 11 and the heat insulating material 20, the side wall in the sound-absorbing plate body 47 so that the noise passing through the plurality of sound wave through holes 12 formed in the surface steel plate 11 is absorbed A plurality of protrusions 41 protruding circularly from 44 are formed, and a cover member 46 made of a material having high permeability is laminated to cover the whole so that the first sound-absorbing space 43 is formed in the protrusions 41. ), A resonance sound absorbing member 40 is formed between the protrusions 41, the second sound absorbing space (45).

The surface steel plate 11 is formed by forming a plurality of sound wave through holes 12 as a porous plate, and may form the sound wave through holes 12 only in a portion of the center as shown in the drawing, or may be formed over the entire surface steel sheet 11. In addition, the smaller the diameter of the sonic through hole 12 is, as defined by the following equation, or the deeper the sonic through hole is, the deeper the resonance rate becomes.

That is, the noise of the resonance absorbing panel had a function of selectively absorbing mid and low frequencies between about 125 Hz and 2 Hz. The sound absorption frequency is determined by the width and depth of the sound absorbing hole 12 of the sound absorbing panel, the opening and closing rate of the sound absorbing hole 12, and the distance from the wall on which the resonance sound absorbing panel 40 is installed. It can be explained by.

≪ Equation &

Figure 112009047594888-PAT00001

f 0: Resonance frequency (㎐), p: Acoustic wave opening and closing rate (%)

t: Effective depth of sonic through (inch) + 0.8 × diameter of sonic through (4)

d: distance between sound absorbing panel and wall

According to the above equation, the smaller the opening and closing rate of the acoustic wave hole 12, the lower the resonance frequency, and the longer the depth of the effective acoustic wave hole or the longer the distance between the resonance absorption panel 40 and the wall, the lower the resonance frequency. In addition, it can be seen that in order to control lower bass frequencies, the thickness of the sound absorbing panel may be increased and the distance between the sound absorbing panel and the wall may be increased. Therefore, the sound absorbing panel of the present invention can maximize the sound absorbing effect by installing the sound wave through hole (12) opening and closing rate by adjusting the thickness or distance of the sound absorbing panel or the distance of the wall or the width of the back of the bone at the construction site according to the environment. .

3A to 3D show protrusions 41 having various shapes of the resonance absorbing panel according to the present invention.

Shapes of the protrusions 41 of the present invention according to the drawings may be variously formed in the shape of a circle, a rectangle, a star, a hexagon, and the like, as shown in FIGS. 3A to 3D of the accompanying drawings. By covering the entire surface of the sound absorbing material with a cover member 46, the sound absorbing force in the first sound absorbing space 43 in the protrusion 41 as well as the second sound absorbing space 45 can be obtained.

In particular, the protrusion 41 of the resonance sound absorbing panel 40 of the present invention may form a sound absorbing induction hole 42 on the front or side thereof to guide the noise sound waves to increase the spatial resonance rate.

In addition, the resonance sound absorbing member 40 of the present invention forms a plurality of protrusions 41 and the second sound absorbing space 45 on the sound absorbing plate 47 to further improve the internal resonance rate of the noise.

The sound absorbing plate body 47 is a building material generally used for sound absorption, and is divided into a porous sound absorbing material and a plate sound absorbing material depending on the structure. The former is a small bubble or thin tube on the surface and inside. There is a (pipe) shaped hole, and the air in this hole is absorbed by the sound energy converted into thermal energy due to the friction generated by the sound waves, and the latter causes sound waves to consume the sound energy while vibrating the plate to obtain a sound absorption effect. Of course, the entire sound absorbing plate 47 may be wrapped with a cover, but it is efficient to cover only the inner side of the sound absorbing plate 47 with a cover. When the cover material is thin glass wool, compressed polyester board, fabric sheet, etc., air can be distributed between the fiber yarns, so that noise is absorbed into the panel, but dust of the sound absorbing plate body 47 cannot pass. .

4A to 4B are enlarged views illustrating a resonance state of sound waves of the resonance absorption panel of the present invention, and FIGS. 5A to 5C are cross-sectional views illustrating resonance states of the resonance absorption panel of the present invention.

That is, as shown in FIGS. 4A and 5A, in the resonant process of the present invention, as described above, the sound wave passing through the sound wave through hole 12 of the surface steel plate 11 may be formed of the protrusion 41 of the internal resonance sound absorption panel 40. It is resonated between the two sound-absorbing space 45 or passed through the front sound-absorbing cover member 46 of the protrusion 41 is absorbed into the inner space 43 to obtain the sound-absorbing effect according to the general resonance.

Furthermore, the resonance absorbing panel 40 of the present invention enters into the cover member 46 through the sound absorbing guide 42 in addition to the general sound absorbing structure as shown in FIGS. 4B, 5B, and 5C. Since the space 45 is guided to the sound absorbing induction hole 42 formed in the side wall 44 of the protrusion 41, the resonance ratio in the space 43 in the protrusion 41 can be increased to improve the overall sound absorption effect.

6A to 6D show various assembly examples of the sandwich sound absorbing panel for building the present invention.

As shown, the surface steel plate 11 is formed in the same shape as the rear steel plate 10, and the sound wave through hole 12 in the center of the surface steel plate 11 or the entire surface plate 11 corresponding to the resonance sound absorbing panel 40. Noise is absorbed by the sound wave.

The heat insulating material 20 is a material used for the purpose of keeping warm or blocking heat, but it is possible to use various materials such as glass fiber, cork, foamed plastic, etc., which is difficult to conduct heat, but it is preferable to use a flame retardant urethane board having excellent heat insulation and flame retardancy. Do.

The urethane board is used as the material of the heat insulator 20 because it is not only excellent in heat insulating property, but also can make the thickness of the sandwich sound absorbing panel as thin as possible and can significantly improve the efficiency of heat insulation. The heat insulating material 20 is installed in close contact with the rear steel plate 10 side of the surface, the back steel sheet 10, 11 is not formed sonic through hole 12.
