SOUNDPROOF SHEET WITH FUNCTION OF NATURAL LIGHTING FOR SHIELDING ARCHITECTURAL OPENINGS}

The present invention is installed so as to shield the opening formed in the building during the construction of various buildings in the process of dismantling the internal formwork installed in the interior of the building (especially the ceiling) noise and dust due to the falling of the formwork through the opening of the building outside Regarding the soundproof sheet for shielding the open part of a building that prevents spillage, in detail, it provides soundproofing and dustproofing performance while improving the light-resisting property that allows light to enter the interior, and is dark It relates to a soundproof sheet for shielding the open part of a building having a mining function capable of improving work efficiency by improving the working environment.

In general, various structures such as apartments, buildings or shopping malls are mostly constructed by pouring concrete. As such, in order to construct a building through pouring concrete, an outer wall formwork made of large iron, that is, a gang form, and an inner formwork (alform, euroform, etc.) installed on the inner wall (including the ceiling) are used. These formwork serves to maintain a predetermined shape and dimensions while the concrete is being cured and to protect the outer wall from the external environment while preventing the leakage of moisture until the concrete hardens.

In these structures, a number of openings are formed to form windows of various sizes, and through the openings, noise and dust are left to the outside in the process of dismantling the internal formwork (Alform, Euroform, etc.) installed inside after concrete curing is completed. There was a problem of release. In particular, the noise and dust caused by the collision of the floor of the falling formwork in the process of dismantling the heavy formwork installed on the ceiling of the building cause a significant amount of noise and dust damage to the surrounding residents, leading to the construction of various civil complaints. Related legal regulations such as noise vibration and scattering dust prevention at construction sites are gradually being strengthened.

Accordingly, various techniques have been proposed to effectively block noise and dust emitted to the outside by shielding the opening of the building when constructing the building. Among these technologies, technologies in the form of soundproof sheets or curtains that are easy to transport and construct are proposed in Japanese Patent Application Publication No. 10-2009-235761 and Korean Patent Application Publication No. 10-1247308.

Japanese Patent Publication No. 10-2009-235761 is for use in various construction and dismantling works, civil works, etc., or in various factories equipped with devices with noise sources, such as soundproof sheets, mesh sheets, and soundproofing. Including a sound absorbing pack filled with a granular porous sound absorbing material fastened through a quilted seam between the sheet and the mesh sheet, the soundproofing and sound absorbing properties were improved, and a flexible soundproofing and sound absorbing sheet having flexibility was proposed.

In Korean Patent Publication No. 10-1247308, it is installed in connection with the formwork at the construction site to prevent dust and noise at the construction site, and it is easy to adjust the size to suit the situation of the site, reducing construction cost by increasing utilization. For the purpose of promoting, a curtain mechanism for shielding a formwork including first and second sound absorbing materials provided between a blackout fabric, a sound insulating material, and an air pocket formed between the blackout fabric and the sound insulating material is provided.

The soundproof sheet or curtain mechanism proposed in Japanese Patent Application Publication No. 10-2009-235761 and Korean Patent Registration No. 10-1247308 is installed in an open part of a building due to the sound absorbing material embedded therein, such as noise or dust. Although it provides an effect of preventing external leakage, there is a risk of safety accidents because workers who work inside must perform work in a dark space because sunlight is hardly penetrated into the interior due to the lack of light or extremely low light.

Due to this, the operator needs to secure light by using a lamp separately during the daytime, and thus an unnecessary power loss occurs. If the lamp is damaged due to carelessness during work, it may be exposed to a fire hazard. In addition, in the cold winter season, since sunlight does not flow inside, it is difficult to maintain the body temperature of the worker, resulting in safety accidents due to rigid muscles, and a number of problems such as deterioration of work efficiency.

Hereinafter, the technical features of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view viewed from one side to explain the soundproof sheet for shielding the open part of a building according to an embodiment of the present invention, and FIG. 2 is a view from the other side of the soundproof sheet for shielding the open part of the building shown in FIG. 1 3 is a view showing a cross-section in a state in which the soundproof sheet for shielding the opening of the building shown in FIG. 1 is installed in the opening of the building.

1 to 3, the soundproof sheet 10 for shielding the open part of a building according to an embodiment of the present invention is interposed between the inner cover 11 and the outer cover 12 to heat the incident noise energy. It is made of a laminated structure in which a sound absorbing material 13 for preventing noise by changing to is laminated.

The soundproof sheet 10 for shielding the opening of the building is installed close to the exterior wall 1 of the building so as to cover the opening 1a formed on the exterior wall 1 of the building, as shown in FIG. It is fixed to a horizontal or vertical stand of the gang form 2 with wires or strings, or a pour material (system gang form, etc.) and is lifted together when the gang form 2 is lifted. Alternatively, after installing a separate bracket to compensate for the gap between the horizontal or vertical stand of the gang form (2) and the exterior wall (1) of the building, fix it to the bracket with a fastening member such as a screw or bolt, and lift it together when lifting the gang form (2). do.

The inner cover 11 is installed on the inside of the soundproof sheet 10 for shielding the opening of the building so as to face the building outer wall 1, as shown in Figure 3, the noise generated inside the building by the inner cover 11 It is made of transparent vinyl having a plurality of incidence holes 11a formed so as not to be reflected and incident on the sound absorbing material 13 embedded inside the inner cover 11 and the outer cover 12.

The incidence hole 11a formed in the inner cover 11 of the inner cover 11 so that the noise generated therein is not reflected by the inner cover 11 but mostly enters the sound absorbing material 13 through the inlet hole 11a. It is desirable to form relatively densely, about 60 to 90% of the total area.

The incident hole 11a incident on the inner cover 11 may be formed in a circular or polygonal structure, but preferably, as shown in FIG. 1, the upper and lower diameters d1 are left and right diameters to increase the incident rate of noise ( It is formed into an oval structure larger than d2). This will be described with reference to FIG. 4.

4 is a conceptual diagram illustrating a process in which noise is incident on an inner cover according to the present invention.

In general, noise that causes pain to surrounding residents during construction is mostly high-frequency noise, and most of this high-frequency noise is generated by impacting the floor by dropping the formwork in the process of dismantling the inner formwork installed on the ceiling of the building.

As shown in FIG. 4, noise (n) generated when the formwork falls and collides with the inner bottom surface of the building is emitted in all directions from the inner bottom surface of the building, some of which are directly incident on the inner cover 11, and some Is reflected by the surrounding wall and then enters the inner cover 11.

As described above, most of the noise (n) generated on the floor surface of the building due to the fall of the formwork is not incident to orthogonal to the inner cover 11 as it propagates from the lower part to the upper part. And enter. Accordingly, by forming the incidence hole 11a of the inner cover 11 into an elliptical structure in which the upper and lower diameters d1 are larger than the left and right diameters d2, as shown in FIG. 1, the incident rate of noise incident to the incident hole 11a Increases and decreases the reflectance.

5 is a view showing to explain another example of the incident hole formed in the inner cover according to the present invention, as shown in Figure 5 (a), the inner cover 11 ', 11' 'formed in the incident hole (11a) ', 11a' ') may be formed in a diagonal shape, or may be formed in a trapezoidal shape in which the size becomes smaller as the outer surface goes from the inner surface of the inner cover 11' ', as shown in FIG. 5 (b).

The sound absorbing material 13 is fixed between the inner cover 11 and the outer cover 12 through a sewing line 15.

The sound absorbing material 13 is made of a single sheet, but this is an example, and may be made of a multi-layer structure in consideration of sound absorption and light transmission, which will be described later.

The sound absorbing material 13 reduces noise by converting sound waves incident on the surface through the incident holes 11a of the inner cover 11, that is, sound waves by converting them into thermal energy through frictional resistance and vibration, so that the sound waves pass as much as possible. By reducing the reflection of the sound wave, the sound absorption rate can be improved.

As the sound absorbing material 13, it is preferable to use a porous sound absorbing material. Porous sound absorbing material is a material with fine holes formed on the surface and inside. When sound waves are incident, viscous friction is generated by air vibration inside the material, and sound waves are converted into thermal energy to absorb noise.

The sound absorbing material 13 according to the present invention is preferably a porous sound absorbing material having an excellent sound absorption rate in a high frequency band of 500 Hz or more corresponding to noise generated when the formwork falls, but to increase the sound absorption rate, increase the thickness of the porous sound absorbing material, or high density When using a porous sound absorbing material, there is a problem in that the transmittance is relatively reduced.

Thus, in the present invention, a porous sound absorbing material having a transmittance of 15% to 60% is used while the sound absorption rate satisfies 0.5 to 0.9 in a high frequency band of 500 hz or more. At this time, as the porous sound absorbing material, polypropylene (PolyproPylene, PP), nonwoven fabric, or polypropylene (PP) and polyethylene terephthalate (PolyEthylene Terephthalate, PET) may be used as a mixed material. In addition, polyester or glass-wool may be used.

Hereinafter, the present invention is to provide a sound absorbing material that can satisfy the sound absorption rate and transmittance.

6 is a view showing a cross-section to explain the sound absorbing material according to another example of the present invention.

Referring to FIG. 6, the sound absorbing material 23 according to another example of the present invention includes an air layer between the first sound absorbing sheet 231, the second sound absorbing sheet 232, and the first and second sound absorbing sheets 232. In order to form 234, a spacer block 233 partially interposed between the first and second sound absorbing sheets 232 is included.

The first and second sound absorbing sheets 231 and 232 may be formed of sound absorbing materials having the same thickness and / or density, or may be made of sound absorbing materials having different thickness and / or density. In this case, when the first and second sound absorbing sheets 231 and 232 are made of sound absorbing materials having different thicknesses and / or densities, the second sound absorbing sheet 232 disposed on the rear side is attached to the first sound absorbing sheet 231. Compared to the above, it is preferable to use a thicker or higher density sound absorbing material.

In an embodiment of the present invention, the first and second sound absorbing sheets 231 and 232 are respectively made of a relatively thin thickness of 2 mm to 10 mm in consideration of transmittance. As described above, when the thicknesses of the first and second flaw sheets 231 and 232 are thin, the sound absorption rate is inevitably lowered, and the sound absorption rate is through the air layer 234 formed between the first and second sound absorbing sheets 231 and 232. Can compensate.

As the first and second sound absorbing sheets 231 and 232 are made of a fluid material, there is a problem in that the air layers 234 formed between them are lost after being installed on the outer wall of the building and contacting each other.

Accordingly, a space between the first and second sound absorbing sheets 231 and 232 is maintained to maintain a constant distance between the first and second sound absorbing sheets 231 and 232 to prevent the air layer 234 from being lost. 233) is partially installed. At this time, the width of the separation block 233 is formed to be approximately 3 mm to 10 mm to maintain a gap between the first and second sound absorbing sheets 231 and 232 from 3 mm to 10 mm.

The separation block 232 maintains the spacing between the first and second sound absorbing sheets 231 and 232, while the sound absorbing sound waves that pass through the first sound absorbing sheet 231 are not emitted to the outside, as a sound insulating material, The sheet may be made of a synthetic resin plate, a metal plate, or a wooden plate having strength so as not to tear the sheet, or may be made of a sponge material cushion material for light weight and flexibility.

In FIG. 6, the sound absorbing material 23 according to another example of the present invention is composed of two first and second sound absorbing sheets 231 and 232, but this is an example, considering three or more sound absorbing sheets in consideration of transmittance and sound absorption. It is possible to use, and further install a spacer block in response to this.

7 is a cross-sectional view illustrating a sound absorbing material according to another example of the present invention.

6, the sound absorbing material 33 according to another example of the present invention includes first and second sound absorbing sheets 331 and 332, a separation block 333, and an air layer 334. And, as described above with reference to FIG. 4, the first fault sheet 331 is inclined based on the second sound absorbing sheet 332 to more stably absorb and block the impact noise generated inside the building. That is, the first sound absorbing sheet 231 is formed so that the upper portion is biased toward the outer wall 1 of the building.

The first sound absorbing sheet 331 is disposed to be inclined at an angle of approximately 10 ° to 45 ° with respect to the second sound absorbing sheet 332, through which the first sound absorbing sheet 331 and the second sound absorbing sheet 332 are disposed. When the volume of the formed air layer 334 is increased, when the sound waves due to the impact noise generated from the lower portion inside the building are incident at a certain angle (diagonal line), the initial shock waves can be rapidly absorbed and blocked. In addition, the inner cover 11 is also inclined at an angle of 10 ° to 45 ° is a structure that can significantly increase the noise absorption rate.

2 and 3, the outer cover 12 is securely fixed to the rear side of the sound absorbing material 13 through the sewing line 15. The outer cover 12 functions as a sound-insulating material that sounds through the sound-absorbing material 13, that is, so that sound waves are not discharged to the outside. The sound insulation material reflects as much of the sound as possible to block the sound, and the less sound transmitted, the better the sound insulation.

The outer cover 12 according to the present invention is made of a synthetic resin series, such as a transparent vinyl sheet, like the inner cover 11 so that sunlight is transmitted for mining, and is not easily torn, the transmittance is 40% or more, preferably It is preferable to form a thickness of 2mm to 10mm so as to be 50% to 70%.

On the other hand, as shown in Figures 1 and 2, the soundproof sheet 10 for shielding the open part of the building according to the present invention to protect the circumference of the inner cover 11, the sound absorbing material 13 and the outer cover 12, It further includes a closing member 14 fixed through a sewing line 15 installed to surround the circumference.

The closing member 14 may be made of synthetic resin, synthetic cloth, or the like, which is not easily torn or damaged. For example, it may be made of a transparent vinyl sheet or dark cloth (tarpaulin).

8 is a conceptual diagram showing to explain the mining function of the soundproof sheet for shielding the open part of a building according to the present invention.

Referring to FIG. 8, the soundproof sheet 10 for shielding an open part of a building according to the present invention is made of a transparent vinyl sheet through which the outer cover 12 and the inner cover 11 can transmit light, and between them The interposed sound absorbing material 13 also uses a low density porous sound absorbing material having a transmittance of 15% to 40%, so that the light irradiated from sunlight passes through the outer cover 12, the sound absorbing material 13, and the inner cover 11 sequentially to construct the building. It can be introduced into the interior of the building to improve the working environment of the building.

9 is a cross-sectional view illustrating a soundproof sheet for shielding an open part of a building according to another embodiment of the present invention.

Referring to FIG. 9, the soundproof sheet 20 for shielding an open part of a building according to another embodiment of the present invention is similar to the soundproof sheet 10 shown in FIG. 3, the inner cover 21, the outer cover 22 and A sound absorbing material 23 is included. And, it further includes a sound insulating material 26 interposed between the outer cover 22 and the sound absorbing material 23 so as to prevent sound waves passing through the sound absorbing material 23 from being emitted.

The sound insulating material 26 may be formed of an air cap having a plurality of air pockets having a convex shape (convex lens shape) in the direction of the sound absorbing material 23. Through this, the light incident on the outer cover 22 is diffused to the inside through a plurality of air pockets so that sunlight is more incident on the sound absorbing material 23, thereby increasing the amount of light entering the interior of the building. In addition, the effect of sound insulation can be seen with the air pocket.

Of course, the soundproof sheet 20 for shielding the opening of a building according to another embodiment of the present invention is also not shown, but the inner cover 21, the sound absorbing material 23, the outer cover 22 and the sound insulating material 26 A circumferential portion may be combined with a finishing material (not shown) fixed through the sewing line 15.
