Description

A building material having dust prevention, sound-proofing and adiabatic function, a floor structure provided the same}

The present invention relates to a building material which is installed on the wall or floor structural material of a multi-family house such as a townhouse, multi-family house, etc. to perform dustproofing, soundproofing, and heat insulation. The present invention relates to a building material having a polyester fiber sheet attached thereto and having a built-in wall or floor structural material to enhance dustproofing, soundproofing, and heat insulation, and a building structural material containing the same.

Generally, in buildings such as multi-family houses or schools where the walls and floors must be shared with neighbors, they are caused by impacts on the floor due to walking indoors, children jumping, falling objects, or moving furniture. Dustproof, soundproofing and insulating materials are used, respectively, to exhibit the effect of absorbing the floor impact sound or the noise of the room to the neighboring generation through the walls and absorbing sound.

An example of such a building material is briefly described with reference to FIGS. 1A to 1D as follows.

In the case of glass insulation used as a thermal insulation material in order to exhibit the sound-absorbing, heat-insulating effect of the building in the prior art, it is manufactured and used in a thickness of 25mm-75mm (shown in Figure 1a), in the case of a urethane foam board of a thickness of 25mm-125mm It is manufactured and used (shown in Figure 1b), foamed polystyrene foam (Styrofoam) is used in a thickness of 10mm-100mm (shown in Figure 1c) depending on specific gravity, and in the case of rock wool (ROCK WOOL RIGID BOAD), 25mm- It is manufactured in 80mm thickness and is mainly used as foamed polyethylene insulation (PE FOAM) or slightly higher carbonized cork board.

The above products are somewhat different depending on the density, but generally, products with a thickness of 30mm-50mm can show some insulation effect. In particular, in addition to natural wood fibers and polyester fibers, foamed polystyrene foam (Styrofoam) and foamed polyethylene foam (P, E FOAM) are used as sound absorbing materials. Since it is not absorbed and passed through as it is, there is a drawback that a full soundproofing effect cannot be expected.

In addition, in the case of multi-family houses or high-rise buildings, the floor is impacted by people walking, falling objects, or moving furniture, so that floor vibrations are emitted to the floor below. Although a lightweight foamed concrete layer or a foamed polystyrene foam layer is provided as a buffer layer on the slab, it does not show a great effect on the sound insulation of the impact sound between floors.

This is because apartment buildings are mostly constructed in the same way as above, but the reality is that vibrations caused by falling objects or jumping impacts of children are transmitted to the lower floors as they are, resulting in noise.

Recently, in order to increase the interlayer floor impact sound blocking effect, as shown in FIG. 1D, vibration damping from the upper layer is somewhat blocked by using a special dustproof material such as anti-vibration rubber pads (PAD) having a thickness of 10 mm to 50 mm. The situation is showing the effect.

2A and 2B are cross-sectional views of the structure of the bottom layer and the bottom layer using the anti-vibration rubber pad (PAD). Here, Figure 2a is a cross-sectional view of a general floor structure material, Figure 2b shows a floor structure material with a built-in anti-vibration rubber pad.

In FIG. 2B, unlike the conventional floor structure of FIG. 2A, a vibration damping rubber pad having a thickness of about 10 mm to 50 mm is installed below the light-weight foam concrete layer to absorb the shock applied from the upper layer by the elasticity of the rubber pad, and transmit the vibration to the lower layer. To some extent.

However, because the concrete slab layer, anti-vibration rubber pad layer, lightweight foam concrete layer, and floor plastering mortar layer are bonded together, the anti-vibration effect on the impact can be halved, and it is essentially floated to reduce the floor impact sound. The hypothesis of the flooring (FLOATING FLOOR) structure or auxiliary ceiling is the most effective, in this case, there is a problem that the floor height is low, the construction cost is high.

Therefore, the present invention has been made to solve the above problems, and is molded by extruding a copolymer of polypropylene and polyethylene (PP, PE COPOLYMER) as a raw material, the middle of which is a plastic double board with an air layer And built-in a thin-walled board with POLYESTER FIBER SHEET with excellent sound-absorbing and insulating effect on both sides thereof. The object of the present invention is to provide a building material that maximizes the sound insulation and insulation performance by sound absorption, sound insulation, and building structures therein.

In addition, the present invention has another object to provide a building material and a building structural material therein, which is much less expensive to manufacture than conventional dust, soundproofing, heat insulating material, and can save energy by the heat insulating effect.

In addition, an object of the present invention is to provide a building material that can be used as an interior finishing material, such as a machine room, an air conditioning room, a performance hall, a gymnasium, and a building structural material therein.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings of FIG. 3.

Building material having a dustproof (방), soundproofing and thermal insulation function according to the present invention and a built-in building structural material is implemented to make the construction cost cheap and simple construction while maximizing the dustproof, soundproofing and insulation effect.

According to the present invention, a method of forming a floating floor structure between the concrete slab layer and the light-foamed concrete layer is effective in order to minimize the floor impact sound transmitted by the impact from the upper layer to the lower layer. It is based on the theory of greatness. Therefore, in the present embodiment, as shown in Figures 3a and 4 to extrude the high-density plastic resin to form a floating floor structure, to absorb and extinguish the shock or vibration introduced from the outside to the center Plastic double board (1) with an air layer for; On the upper and lower surfaces of the double board (1) is proposed a structure in which the polyester fiber sheets (2, 3) having excellent sound absorption and heat insulation effects are attached.

Here, the double board 1 serving as a center substrate is connected to the upper and lower plates 11 and 12, and the upper and lower plates 11 and 12, with a predetermined interval to form an air layer 14 therebetween. The partition plate 13 is arranged in a straight line. In addition, the double board (1) is a plastic board manufactured by extrusion molding a high-density polypropylene and polyethylene copolymer (PP, PE copolymer) raw material, and exhibits a sound insulation effect of low frequency sound is not absorbed well in a general sound absorbing material, Light weight, high strength, water resistance, heat resistance (cold resistance), durability and chemical resistance is excellent.

In addition, in the structure of the plastic double board 1 as described above, the passage formed by the partition plate 13 arranged at a predetermined interval is an air layer that can receive the vibration sound due to the impact introduced through the upper plate of the double board ( 14), the air layer 14 of the plastic double board (1) is to exhibit the vibration and dust insulation effect of the impact vibration. The thickness of the plastic double board (1) layer has a thickness of 2mm ~ 6mm to ensure the air layer, the weight is manufactured by 500g / ㎡ ~ 2,000g / ㎡ for the compressive strength. In addition, the double board 1 in this embodiment can be produced by mixing a flame retardant material (not shown) with a copolymer of polypropylene and polyethylene for flame retardant treatment.

In addition, as shown in FIGS. 5A and 5B, the double board 1 further includes a joint grip 15 to extend its length by a predetermined length so that the double board 1 can be installed according to the area of the concrete slab. The joint grip 15 is composed of a combination of upper and lower plates and a vertical member has a structure that can fit the end of the double board (1). 5A shows a grip having a substantially I-shaped cross-section in order to extend the double board 1 horizontally. Figure 5b shows a grip that can connect the double board horizontally and vertically, the second grip (15 ') extending vertically at a predetermined interval on the upper portion of the "c" shaped first grip 15 is coupled Structure.

A hole 16 for communicating between the air layers 14 formed in the partition plate 13 may be formed in the vertical member of the joint grip 15. By such a structure, the vibration or impact sound introduced into the air layer 14 passes through the neighboring air layer and diffuses into the air layer of the entire double board 1, thereby increasing the extinction rate of the vibration or impact sound.

As another embodiment of the double board 1, as shown in FIG. 3B, the partition 13 'connecting the upper and lower plates may have a honeycomb structure. In this case, there is an effect that can further increase the strength of the double board (1).

On the other hand, the polyester fiber sheet (POLYESTER FIBER SGEET) (2, 3) layer attached to both sides of the plastic double board (1) layer is excellent sound absorption, heat insulation, and includes an air layer between the fibers, elasticity By having it, the role of vibration absorption due to shock, and the sound absorption and heat insulation effect are enhanced.

The polyester fiber sheets (2, 3) in the present embodiment is to use a heat-sealed sheet (SHEET) after the polyester is laminated to make a web (WEB) state through a carding process (CARDING), In order to increase the thermal insulation, it is manufactured with a thickness of 2mm-8mm and a weight of 200g / ㎡-800g / ㎡.

The sound insulation (sound absorption, sound insulation), insulation, and dustproof effects of the present invention will be described in more detail by dividing each layer as follows.

First, the polyester fiber sheet 2 adhered to the upper surface includes an air layer between the fibers, so that the sound absorbing effect of the high frequency sound and the heat insulating effect are exhibited simultaneously, and the plastic double board layer manufactured by molding a high density plastic resin (1). ) Shows the sound insulation effect of low frequency sound like the double wall or the double window has good sound insulation effect.

In addition, the air layer 14 formed between the plastic double board layer can absorb the vibration sound generated by the impact vibration in the upper layer directly down to the lower layer can exhibit the effect of the insulation layer with the dustproof effect by the buffer role. The polyester fiber sheet 3 attached to the lower surface has a sound absorption effect and a thermal insulation effect of high frequency sound, like the polyester fiber sheet 2 attached to the upper surface.

The building material configured as described above has a higher heat insulation effect than the heat insulating material (thickness 30mm-50mm) used in the prior art even with a thin thickness of about 10mm, and the sound absorbing material and the vibration-proof rubber pad used in the prior art. Compared to these, by placing air layer in the center part, it is possible to maximize the dustproof and soundproof effect.

In addition, the size of the building material is usually manufactured in a width of 60cm ~ 120cm in length can be adjusted as needed.
