Description

{TEMPORARY SOUNDPROOF BOARD}

The present invention relates to a hypothetical sound insulation panel, and more particularly, to a mold-type mold that can be easily formed by molding a mold through a synthetic resin material, and is a fence- Thereby preventing the transmission of the sound.

Generally, the construction site such as the construction site divides the construction area to block the entrance of the general public, and a construction fence is installed to shield the inside and outside of the construction site.

Such a false fence has been conventionally limited to a simple fence function. Recently, however, a soundproof structure including a soundproof plate has been applied to prevent noise and dust generated in the construction site, thereby preventing generation of complaints due to construction site noise or dust.

As described above, most of the conventional soundproofing boards for use in the present invention use metallic materials such as aluminum, iron plate, or galvanized steel plate for durability, and they include a perforated structure. They are fastened to a plate- have.

In addition, most of them use a sound absorbing material such as styrofoam or glass fiber to improve sound absorption.

However, since most of the conventional soundproofing panels are made of a metal material, they have a disadvantage in that they are heavy in weight and relatively high in manufacturing cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. The present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The hypothetical sound insulation panel according to the embodiment of the present invention is a fence-type product for preventing noise and dust generated in a construction site from being transmitted to the outside, and is used for assembling to a plate-type rear panel or the like.

The above-mentioned temporary sound insulation board is made of a synthetic resin material so as to be able to maintain the mechanical strength and to reduce the weight as well as the manufacturing cost compared with the use of the conventional metal material, and to easily form and shape a desired shape with excellent formability.

As shown in Figs. 1 to 3, the hypothetical sound insulation board 100 is made of a plate-shaped body 110 formed of a thermoplastic synthetic resin material having mechanical strength and molded into a mold metal.

At this time, the plate-shaped body 110 is formed with a plurality of perforations 120 at regular intervals for blocking noise and dust.

Here, the perforation 120 may have a circular shape, and the shape of the perforation 120 may be deformed so as to enhance noise blocking effect through negative reflection and scattering.

For example, it can be made into a star shape, and it is easy to manufacture because it is molded by using a synthetic resin material.

Here, the perforations 120 may be formed at intervals of 20 to 100 mm, and more specifically at intervals of 40 to 60 mm.

When the perforations 120 are formed in a circular shape, as shown in FIG. 4, the sound damping protrusions 121 having a concave-convex structure may be formed on the inner surface of the perforations 120 to increase the noise blocking effect.

The sound attenuating protrusion 121 reflects and scatters sound through the concavo-convex structure to attenuate noise. Since the sound attenuating protrusion 121 induces reflection or scattering through the impact of sound introduced into the perforation 120, 120, the intensity of the sound wave is reduced, and the noise can be further reduced.

Here, the noise damping protrusion 121 may be semicircular, wedge-shaped, or the like.

The perforations 120 are formed in a plate-shaped body 110 having a constant thickness. The perforations 120 are formed in a tapered shape so that the diameter decreases toward the rear outlet (b) as compared to the front inlet (a) It is preferable to configure the filter so as to increase the blocking efficiency of the dust.

Here, it is preferable that the front inlet (a) side is formed to have a diameter of 10 to 15 mm and the rear outlet (b) side to have a diameter of 8 to 12 mm for the tapered structure of the perforation 120.

More specifically, the front inlet (a) side may be formed to have a diameter of 10 mm, and the rear outlet (b) side may be formed to have a diameter of 8 mm.

The temporary sound insulation board 100 is a plate-shaped body 110 formed by molding using a thermoplastic synthetic resin material and having a predetermined thickness, and is made of polyvinyl chloride (PVC), acrylonitrile butadiene styrene (ABS) copolymer resin, and a glass fiber-reinforced thermoplastic resin.

At this time, it is preferable that no plasticizer is added to the polyvinyl chloride (PVC) so as to maintain hardness, and the glass fiber-reinforced thermoplastic plastic is preferably a mixture of polypropylene and glass fiber.

Here, the polyvinyl chloride (PVC) can provide mechanical strength and excellent moldability, and can exhibit flame retardancy, water resistance, weather resistance, etc., and can be reduced in weight and manufacturing cost compared to conventional metal materials.

Here, the ABS resin can provide mechanical strength and excellent moldability, and can exhibit heat resistance, impact resistance, and the like, and can reduce weight and manufacturing cost compared to conventional metal materials.

The glass fiber-reinforced thermoplastics obtained by mixing the polypropylene with glass fibers can provide mechanical strength and moldability, as well as exhibit flame retardancy and the like, and can be significantly reduced in weight as compared with conventional metallic materials.

In addition, the plate-shaped body 110 is formed and displayed together with a mold for molding by a mold, and is provided with a fixing display unit (not shown) for fixing the fixing and fixing of the temporary sound insulation board 100, 130).

It is possible to assemble more easily and quickly than when the temporary sound insulation board 100 is fixed to the rear panel or the like through the fixed display unit 130 for screws.

Therefore, the present invention can be easily manufactured with excellent formability through the built-in sound insulation board 100 of the present invention, and the weight and manufacturing cost can be reduced as compared with the conventional metal sound insulation board, and the mechanical strength can be maintained , And the soundproof efficiency can be improved through the tapered piercing structure.
