Abstract

The present invention relates to an incombustible and sound absorbing panel. More specifically, the incombustible and sound absorbing panel is configured to include a surface member made of polyurethane fibers while having a plurality of holes thereon and a glass board body. The body includes a plurality of primary sound absorbing grooves and sound absorbing protrusions formed thereon to enhance a sound absorbing efficiency. The body is also semi-incombustible to be significantly safe from fire. According to the present invention, the incombustible and sound absorbing panel disperses the sound input through the holes using the primary sound absorbing grooves and then by secondarily using the sound absorbing protrusions protruding therein, thus ensuring excellent sound absorbing performance. The body is made of glass boards while a surface material is made of a synthetic resin material to be lightweight overall. Accordingly, the incombustible and sound absorbing panel is able to prevent sagging or releasing due to gravity even when being installed in a wall or a ceiling.

Description

{INCOMBUSTIBLE AND SOUND ABSORBING PANEL}

The present invention relates to a fire-extinguishing panel, and more particularly to a fire-extinguishing panel, which comprises a surface member formed of polyurethane fibers having a plurality of holes formed therein and a body formed of a glass board, and a plurality of primary sound- So that the efficiency of sound absorption is high and the semi-fireproof is formed, which is very safe for fire.

Generally, the building forms a foundation concrete frame and forms a wall surrounding the frame.

Then, in order to decorate the wall, the interior of the wall is plastered or the interior and exterior materials are attached to the wall.

Most of the interior and exterior materials are made of a synthetic resin material. Since the above materials are not flammable or non-flammable, they are a major cause of safety accidents such as a large amount of toxic gas being discharged when a fire occurs.

In recent years, interior and exterior materials have been developed and supplied so as to prevent fire or burning due to fire due to use of non-combustible materials.

However, the conventional non-flammable inner and outer materials have a problem that the workability is very low, and that the middle guide is required to be applied.

In order to solve the above-mentioned problem, Korean Patent Registration No. 906297 discloses a prefabricated flameless panel using artificial marble as a fastening means.

The conventional prefabricated flame retardant panel comprises a polygonal plate-shaped inner panel 10 formed of a fireproof material as shown in Fig. 1; A fastening means 20 attached to the periphery of the inner panel 10 and formed with an arm fastening means 21 and a male fastening means 22 formed by joining pieces of marble; A fixing member 30 formed at one end of the fastening means 20; And an outer panel 40 attached to one surface of the inner panel 10.

In recent years, regulations on noise have been increasing, and it has become especially important to provide soundproofing facilities in a wide space such as schools and auditoriums.

In order to install the sound-absorbing or sound-absorbing structure, a separate frame is formed on the wall surface, and a sound-absorbing panel is inserted into the frame and then the surface is treated again.

Background Art [0002] A technique relating to a conventional interior material capable of sound absorption is disclosed in Korean Patent Publication No. 2011-0013860, Utility Model Registration No. 0403892, and the like.

However, the conventional fire-extinguishing interior material (panel) has the following problems.

(1) Sound absorption performance is poor, so that a ringing phenomenon still occurs when a panel is installed as a whole.

(2) It is thick and heavy, making installation and construction difficult.

In order to overcome such a problem, the present invention is characterized in that a body having a first sound absorbing groove formed in a plurality of rows and having a sound absorbing protrusion formed inside the first sound absorbing groove;

And a surface member attached to the upper surface of the body by an adhesive and formed of polyurethane fibers and having a plurality of holes.

According to the smoke-absorbing panel of the present invention, the following effects are produced.

(1) Sounds coming in through the holes are dispersed in the primary sound-absorbing grooves, and are dispersed in a second order by the projecting sound-absorbing protrusions so that the sound-absorbing effect is excellent.

(2) The body is made of glass board and the surface material is made of synthetic resin material, so it is very light overall and even if it is installed on a wall or ceiling, there is no sagging or dropping due to gravity.

1 is a perspective view of a conventional sound-absorbing panel.
2 is a cross-sectional view of a fire-extinguishing panel formed in accordance with a preferred embodiment of the present invention;
3 is a plan view of a fire-extinguishing panel formed in accordance with a preferred embodiment of the present invention.

The present invention is characterized in that a body (100) in which a first sound absorbing groove (110) is formed in a plurality of rows and a sound absorbing protrusion (120) is formed in a first sound absorbing groove (110);

And a surface member 200 attached to the upper surface of the body 100 with an adhesive and formed of polyurethane fibers and having a plurality of holes 210 formed therein.

The body 100 is preferably formed to have a thickness of 9 to 12 mm and is formed of an E-glass board. The E-glass board is foamed glass fiber and is light and has high heat resistance.

When the body 100 has a thickness of 9 to 12 mm, the body is easily broken if it is formed to have a width of 9 mm or less. If the body 100 is formed to have a thickness of 12 mm or more, the body 100 is heavy.

A plurality of primary sound-absorbing grooves 110 are formed in the body 100 in the longitudinal direction. The primary sound-absorbing grooves 110 are formed to have a depth of 10 mm to 20 mm and a width equal to the width.

The sound absorbing protrusion 120 protrudes in a lower portion of the primary sound absorbing groove 110. The sound absorbing protrusion 120 has a wedge shape having a half width and a height of the first sound absorbing groove 110, .

The first sound absorbing groove 110 absorbs sound transmitted through the hole 210 or sound transmitted by the vibration of the surface member 200 to the sound absorbing protrusion 120, So that the sound can be canceled.

The primary sound-absorbing grooves 110 may be radially formed in the center of each unit panel, or may be formed in a circular band.

The surface member 200 is formed of polyurethane fiber, and the surface of the polyurethane fiber is coated with a nonflammable material.

The non-combustible material is formed by coating a product such as a general liquid aerogel inorganic binder, and is formed so as not to block the hole 210. [

A plurality of holes 210 are formed at regular intervals, and are formed to be very small with a diameter of 1 to 10 mm. At least a hole of at least 3 mm or more should be formed to improve the sound absorption effect.

Hereinafter, the operation and effects of the smoke-absorbing panel formed as a preferred embodiment of the present invention will be described.

In order to test the quasi-incombustibility of the fire-extinguishing panel of the present invention, a test piece was formed, and when the surface was heated with a torch for 10 minutes, the fire did not spread, and the residual flame was left for about 24 seconds when turned off.

In addition, a reverberation experiment was commissioned to measure the sound absorption rate, and the sound absorption rate was 38 ~ 43% as measured by the KS F 2805 method.

In the reverberation experiment, it was confirmed that the primary sound-absorbing grooves 110 were formed in the shape of a circular strip with the best effect (sound absorption ratio 43%).

According to the smoke-absorbing panel of the present invention, sound coming in through the holes is dispersed in the primary sound-absorbing grooves, and is dispersed by the sound-absorbing protrusions protruding from the inside to form a glass board. It is formed of a synthetic resin material and is very light as a whole, so that even when installed on a wall surface or a ceiling, effects such as sagging due to gravity and absence of dropout occur.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art without departing from the scope of the invention as defined by the appended claims.
