Hereinafter, a configuration of the present invention will be described with reference to the accompanying drawings.

1 is a perspective view according to a first embodiment of the present invention, Figure 2 is a partially cutaway perspective view according to a first embodiment of the present invention.

As illustrated, the double sandwich panel for building according to the first embodiment of the present invention includes an inner wall 10 formed in a square shape, an outer wall 11 correspondingly installed in the same shape, and the inner and outer sides. The heat insulating material 20 and the sound absorbing material 30 which are installed between the walls 10 and 11, and the sound absorbing structure 40 provided in the center of the said sound absorbing material 30 are comprised.

That is, the inner and outer walls 10 and 11 are installed at intervals to install the heat insulating material 20 and the sound absorbing material 30, and the material is zinc steel sheet and the thickness of the wall is about 0.45 mm to 0.5 mm to be.

The inner and outer walls 10 and 11 are joined using an adhesive when the heat insulating material 20 and the sound absorbing material 30 are bonded to each other. If the material of the heat insulating material 20 is a urethane foam, the urethane foam is naturally formed by the foaming property of the urethane. It is combined with the heat insulating material (20).

In addition, when the outer surface of the inner wall 10 is applied to paint or waterproof coating according to the application or to attach a variety of building materials, such as tiles, marble, the panel is convenient without a separate finishing work in a place where sound absorption is required. The design value of the panel can be increased.

The outer wall 11 is formed in the same shape as the inner wall 10, the sound absorbing hole 12 is formed in the approximately center portion of the outer wall 11 corresponding to the sound absorbing structure 40, the sound absorbing hole Through 12, air and noise are absorbed into the panel.

The heat insulator 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, polyethylene, etc., which is difficult to conduct heat, but a flame retardant urethane board having excellent heat insulation and flame retardancy is used. It is desirable to.

The use of the urethane board as the material of the heat insulator 20 is because it is not only excellent in heat insulation, but also can make the thickness of the sandwich panel as thin as possible, and can greatly improve the efficiency of heat insulation.

The heat insulating material 20 is installed between the inner and outer walls 10 and 11, and the sound absorbing material 30 and the sound absorbing structure (vertically) in the longitudinal center portion corresponding to the sound absorbing hole 12 of the outer wall 11. The coupling space 21 to which the 40 is coupled is formed.

The sound absorbing material 30 is a building material generally used for absorbing sound, and is divided into a porous sound absorbing material and a plate-shaped sound absorbing material depending on the structure. The former is a small bubble or thin tube on the surface and inside thereof. 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 absorbing effect.

As a material of the sound absorbing material 30, veneer board, gypsum board, fiber board, asbestos board, polyethylene, etc. are generally used, but it is preferable to use glass fiber in consideration of flame retardancy.

Of course, the entire sound absorbing material 30 may be wrapped with a cover, but only the inner side of the sound absorbing material 30 may be wrapped with a cover.

When using a thin glass wool or compressed polyester board, a fabric sheet, etc. as the cover material, since the air can be distributed between the fiber yarns, the noise is absorbed into the panel, but the dust of the sound absorbing material 30 does not pass.

On the other hand, the sound absorbing material 30 may combine an oil, an inorganic material or a fabric sheet having both flame retardancy and dehumidification at the same time.

For example, in the case of using the sound absorbing material 30 combined with the dehumidifying agent, moisture in the air is absorbed through the sound absorbing hole 12 of the outer wall 11 with noise while being in contact with the air, and the sound absorbing structure 40 again. Along the sound absorbing passage 41 of the dehumidifying agent is coupled to the sound absorbing material 30 is moved.

 This moisture is adsorbed on the sound absorbing material 30, and when the air is dried, the moisture is desorbed to blow out moisture in the air.

In addition, when the air freshener is bonded to the sound absorbing material 30, the air freshener passes through the sound absorbing passage 41 of the sound absorbing structure 40 through the sound absorbing hole 12 of the outer wall 11, like the desorption action of water. You can expect a directional effect, such as spreading into the air.

The sound absorbing structure 40 is installed in the coupling space 21 of the heat insulating material 20, and the sound absorbing passage 41 corresponding to the portion where the sound absorbing hole 12 of the outer wall 11 is drilled is formed in the vertical direction. do.

When the sound absorbing structure 40 is coupled to the coupling space 21 of the heat insulating material 20, the sound absorbing material 30 is first installed on the inside, after, and inside the coupling space 21, so that the sound absorbing material 30 is the sound absorbing structure 40. The sound absorbing structure 40 is coupled to the coupling space 21 in the form of surrounding the upper, lower and back of the.

3 is a partially cut-away perspective view according to a second embodiment of the present invention.

As shown, the second embodiment is the same as the structure of the first embodiment described above except that the front surfaces of the outer wall 11 and the heat insulating material 20 are formed in an uneven shape.

That is, since the outer wall 11 provided at intervals from the inner wall 10 is formed in the form of irregularities, the heat insulating material 20 installed between the inner and outer walls 10 and 11 is also formed in the form of the irregularities. .

In the recessed recessed portion of the outer wall 11, a sound absorbing hole 12 is drilled, and the recessed recessed portion in front of the heat insulating material 20 is coupled to the sound absorbing structure 40 and the sound absorbing material 30, as in the first embodiment. ) Is formed.

That is, the inner wall 10 is composed of a rubber-like double plate to improve the waterproof effect, and by improving the durability of the outer wall 11 by forming the front surface of the outer wall 11 in the form of unevenness. As the convex portion of the outer wall 11 can be thickly combined with the thickness of the interior material can further improve the sound absorbing effect.

Looking at the structure of the inner wall 10 in more detail, it consists of a base sheet of 4mm thickness made of a primary rubber material on the inside, by forming a rubber layer by applying a membrane waterproofing agent (rubber) to the back of the secondary base sheet I construct a double board

And the heat insulating material 20 coupled between the inner and outer walls 10 and 11 is a urethane board that is installed toward the inner wall 10 and a flame-retardant board that is installed toward the outer wall 11 (G / W 48 (flame retardant class 2). It is formed into a double structure of)).

Since the front surface of the flame-retardant board is installed toward the outer wall 11 is formed in the same concave-convex shape as the outer wall 11, the concave portion of the flame-retardant board is formed with a coupling space 21 to which the sound absorbing structure 40 is correspondingly coupled. .

The flame retardant board in the form of a block surrounding the upper and lower portions of the sound absorbing structure 40 is coupled to the upper and lower portions of the coupling space 21.

The outer wall 11 is a zinc plate, the thickness is made of 0.45mm ~ 0.5mm, the sound absorbing hole 12 is perforated in the recessed portion of the outer wall (11).

Since the sound absorbing material 30 is formed in a shape, the sound absorbing structure 40 is installed in the coupling space 21 in the form of surrounding the upper, lower, left, right and back surfaces.

On the other hand, it is also possible to couple the atheroscle sheet between the inner and outer walls 10 and 11 so that the panel according to the first to fourth embodiments has a nonflammable or flame retardant function.

Atyrone sheet is a plate-like semi-rigid foam that is extruded and foamed after mixing a foaming agent, a flame retardant or a non-flammable agent in polyethylene resin, and has excellent properties such as heat insulation, water resistance, buffering property, chemical resistance, flame retardancy, or incombustibility. Atyrone sheet commonly used for civil, building and industrial insulation due to its light weight and easy workability.

On the other hand, in order to absorb all the noise of the upper, lower, left, right, the sound absorbing passage 41 formed on the front of the sound absorbing structure 40 may be formed in a radial shape.

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

Dispersed downward and moved to the sound absorbing material 30 provided up and down of the sound absorbing structure 40, the noise reaching the sound absorbing material 30 is absorbed into the sound absorbing material 30 is extinguished.

If you want to absorb the noise that is transmitted quickly up and down, such as the impact sound that children play, you can install the panel so that the sound absorbing passage 41 of the sound absorbing structure 40 is vertical, and the noise flowing sideways like the floor and the ceiling. In the case where the sound absorption is desired, the panel may be constructed so that the sound absorbing passage 41 of the sound absorbing structure 40 becomes horizontal.

In the second embodiment, since the outer wall 11 is formed in an uneven shape, the heat insulating material 20 coupled to the inside becomes thicker as much as the convex portion of the outer wall 11, so that an improved heat insulating effect can be expected.

Figure 4 is a partially cutaway perspective view according to a third embodiment of the present invention.

As shown, the noise absorbed through the sound absorbing hole 12 of the outer wall 11 moves to the sound absorbing material 30 along the sound absorbing passage 41 of the sound absorbing structure 40 and reaches the sound absorbing material 30. Is absorbed into the sound absorbing material 30 and disappears.

In addition, in the third embodiment, since the front surface of the outer wall 11 is formed in a concave-convex shape, not only can the durability of the outer wall 11 be further improved, but also a flame-retardant board coupled to the concave portion inside the outer wall 11 is provided. Since it is thicker than the thickness of a general flame retardant board, it can double the sound absorption and flame retardant effect.
