Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [

The present invention relates to an opening portion shielding plate of a building, which is installed to shield an opening portion of a building in order to prevent noise and dust from flowing out to the outside through an opening portion of the building in a process of dismantling a formwork during the outer wall construction of a building using gang- More particularly, the present invention relates to an opening of a building which prevents noise or dust from flowing out through a gap due to a gap between an outer wall of a building and an opening portion of a building, and a shielding member for shielding a gap The present invention relates to an opening portion shielding plate of a building.

Generally, a building such as an apartment, a building or a shopping mall is constructed by concrete pouring on the outer wall, and an outer wall form made of a large-sized iron, that is, gang-foam is used for constructing the outer wall of the building. These gypsum protects the outer wall from the external environment while preventing the leakage of water until the concrete is hardened and the role of maintaining the shape and size while the concrete is cured.

In this structure, a plurality of open portions are formed to form windows of various sizes, and in the process of disassembling the inner mold (euro foam, aluminum foam, etc.) installed inside the concrete after curing of concrete through the open portion, There was a problem of being emitted. Especially, the noise and dust caused by the collision of the floor of the falling form in the process of dismantling the heavy dies that are installed in the ceiling part of the building gives the surrounding residents a considerable amount of noise and dust damage, Related legal regulations such as noise vibration and fugitive dust prevention at construction sites are increasingly being strengthened.

To solve these problems, Korean Patent Registration No. 10-1116464 (registered on Feb. 07, 2012), Korean Registered Patent No. 10-1386054 (Registered on Apr. 20, 2014), Korean Registered Utility Model No. 20-0479596 When the outer wall of the building is constructed, the opening portion of the building is shielded to prevent noise and dust from flowing out to the outside through the opening portion, and after the mold release, A shielding plate capable of being reused by shielding an opening formed in the upper layer thereof has been proposed.

However, since the shielding plates proposed in the above-mentioned prior art documents are formed in the shape of an integral rectangular plate, there is a disadvantage in that it is troublesome and complicated to install the gang-shaped plate. The reason for this is in the structural characteristics of the gang form. In the gang form, horizontal reinforcements are installed at the bottom of the stringers to reinforce a plurality of stringers. Such a horizontal reinforcing bar is disposed so as to overlap the open portion of the ordinary building in the state where the gang-foam is installed on the outer wall of the building. Therefore, in order to install the shield plate on the stringer, the installation work is complicated because the horizontal reinforcement strip must be cut off and the shield plate must be fixedly installed.

In order to solve such a problem, the present applicant has proposed Korean Utility Model Registration No. 20-0483370 (registered on Apr. 27, 2017), which was registered on April 27, Korean Utility Model Registration No. 20-0483370 proposes a device for shielding the open portion of a building including a shield plate divided into upper and lower portions by a horizontal reinforcing bar of a ganged plate so that the horizontal reinforcing bar is not cut and removed, And it was possible to stably construct it.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view for explaining a split shield according to the prior art; FIG.

1, a conventional shielding plate 10 according to the prior art is installed at the upper part of the horizontal reinforcing base 4c of the gangue 4 in order to shield the opening 1a formed in the outer wall 1 of the building And a lower plate 12 provided below the horizontal reinforcement band 4c as a boundary between the upper plate 11 and the horizontal reinforcement band 4c.

The upper plate 11 is fixed to the stringer 4b (or the side beam) at the lower side of the plate 4a of the gangue 4 so that a plate 4a and a plate 4a are provided between the upper plate 11 and the outer wall 1 of the building, A gap g corresponding to the thickness obtained by subtracting the upper plate 11 from the thickness of the horizontal bar supporting the upper plate 11 is formed. Of course, it is possible to manufacture the upper plate 11 relatively thick considering the distance from the outer wall 1 of the building, but the efficiency is lowered due to the difference in spacing depending on the construction site, the thickness of the shield plate becomes thick, Causing it to rise.

Accordingly, a method of making the edge of the soundproof panel of the dice shielding device close to the outer wall of the building using the pressing member proposed in Korean Patent No. 10-1386054 may be applied to the partitioning shield plate 10, but in this case, 11 and the lower plate 12, the installation work is complicated and the installation cost can be increased.

The guide rail of the unit panel is brought into close contact with the outer wall of the building using the gasket proposed in Korean Utility Model Registration No. 20-0485750 (registered on Feb. 20, 2018) However, this method is complicated in that the structure of the unit panel functioning as the shielding plate is complicated and the noise emitted through the opening of the building, that is, when the sound wave hits the guide rail of the unit panel The sound is amplified due to the resonance phenomenon, so that there is a disadvantage that the sound insulation effect is insufficient.

In addition, the above-mentioned crevice sealing methods proposed in Korean Patent No. 10-1386054, Korean Registered Utility Model No. 20-0485750, and Korean Registered Utility Model No. 20-0479596 are basically the same in that the shielding plate has a rigid material, For example, it can be applied to a structure made of a metal material. However, Japanese Laid-Open Patent Application No. 10-2009-0235761 (Published on October 15, 2009) and Korean Patent No. 10-1247308 (Registered on March 31, 2013) The present invention has a limitation that it can not be applied to a shielding plate made of a flexible soundproof sheet.

1, reference numeral 2a designates an upper cage, 2b designates a lower cage, and 3 designates a safety footrest installed on an upper part of a foot plate 5 horizontally installed in the cage.

The upper plate 21 is provided on the upper side with the horizontal reinforcement strip 4c of the gangue 4 as a boundary. The upper plate 21 may be fixed to the stringers 4b of the gang foam 4, or a cross bar (not shown). Or it may be fixed to at least one side of the gang form 4 or the upper cage 2a or the lower cage 2b through a separate supporting member such as a rod-like support or a fixing bracket.

In addition, a vacuum layer or an air layer may be further formed therein, and the vacuum layer and the air layer may have various shapes such as a circle, an ellipse, a square, or a polygon.

Meanwhile, the upper plate 21 may be a single sheet, or may be formed as a divided plate in which a plurality of plates are divided, and then assembled together through separate fastening members or adhesive members.

In addition, the upper plate 21 may have a soundproof sheet structure. For example, the upper plate 21 may include at least one of a sound absorbing material and a sound insulating material to block noise.

Further, the upper plate 21 may further include a heat insulating material.

In the present invention, the sound absorbing material may be any material capable of absorbing noise. For example, a material formed with pores into which noise flows inward is used.

The inner cover 211 is installed inside the upper plate 21 so as to face the opening portion 1a of the building.

The inner cover 211 is a member having a plurality of through holes so that noise is not reflected by the inner cover 211 but is mostly incident on the inner cover 211 and the sound absorbing portion 213 built in the outer cover 212. [ ≪ / RTI > For example, a mesh network.

The sound absorbing portion 213 may be fixed between the inner cover 211 and the outer cover 212 through a wire or seam 216. Of course, they may be attached to each other through a separate adhesive.

The sound-absorbing portion 213 converts noise, that is, sound waves, which are incident on the surface of the sound-absorbing material through the inner cover 211, into heat energy through frictional resistance and vibration to reduce noise. As a result, The reflection can be lowered and the sound absorption rate can be improved.

As the sound absorbing portion 213, it is preferable to use a porous sound absorbing material. The porous sound absorbing material is a material having fine holes formed on its surface and inside. When a sound wave is incident, viscous friction occurs due to air vibration inside the material, and sound waves are converted into thermal energy to absorb noise.

It is preferable that the sound absorbing part 213 according to the present invention uses a porous sound absorbing material having a high sound absorption rate in a high frequency band of 500 Hz or more corresponding to the noise generated when the form falls.

For example, the sound absorbing portion 213 according to the present invention uses a porous sound absorbing material that satisfies a sound absorbing ratio of 0.5 to 0.7 in a high frequency band of 500 Hz or more. As the porous sound absorbing material, polypropylene (PP), a nonwoven fabric, or a mixture of polypropylene (PP) and polyethylene terephthalate (PET) may be used.

The first and second sound absorbing sheets may be made of a sound absorbing material having the same thickness and / or density, or may be made of a sound absorbing material having different thicknesses and / or densities.

For example, when the first and second sound absorbing sheets are made of a sound absorbing material having different thicknesses and / or densities, the second sound absorbing sheet disposed on the rear side (away from the opening of the building) It is preferable to form it thicker than the sound-absorbing sheet, or to use a high-density sound-absorbing material. For example, a sound absorbing material having a thickness of 5 mm to 20 mm is used as the first and second sound absorbing sheets in consideration of the sound absorbing ratio. The sound absorption ratios of the first and second sound absorbing sheets are compensated through the air layer formed between the first and second sound absorbing sheets.

The lower plate 22 is installed on the lower side with respect to the horizontal reinforcing table 4c of the gantry 4. The lower plate 22 may be fixed to any one of the horizontal reinforcing bar 4c, the stringer 4b, the plate 4a, or the cross bar (not shown) of the gangue 4. Or the gang form 4, the upper cage 2a or the lower cage 2b.

Of course, the lower plate 22 may be made of any one of acrylic, Lexan (product name), polycarbonate or transparent plastic in order to improve the light-transmitting property by transmitting light. In addition, a vacuum layer or an air layer may be further formed therein, and the vacuum layer and the air layer may have various shapes such as a circle, an ellipse, a square, or a polygon.

The lower plate 22 may be formed of a single sheet, or may be formed of a plurality of divided plates, and then assembled together through separate fastening members or adhesive members.

On the other hand, the upper plate 21 and / or the lower plate 22 may be further provided with ventilation and mining doors (not shown) on at least a part thereof. For example, a door for opening and closing an opening formed in at least one side portion of the lower plate 22 can be detachably installed. At this time, the door may include at least one of a sound absorbing material and a sound insulating material which are the same as the lower plate 22, and may be fixed to the lower plate 22 through a removable attachment member such as a Velcro, a magnet, a hook or a zipper.

2, the shielding member 23 is provided at least in a gap between the upper plate 21 and the outer wall 1 of the building, for example, at least a gap portion formed in upper, lower, left, and right spaces between the upper plate 21 and the shielding member 23 And is installed in any one space to seal the gap between the upper plate 21 and the outer wall 1 of the building.

The shielding member 23 includes at least one of a sound absorbing material and a sound insulating material. Preferably, the sound absorbing material absorbs and removes noise (sound waves) in preference to the sound insulating material which can diffuse noise due to the occurrence of vibration (wave) due to the collision of sound waves.

The shielding member 23 may be made of a material having elasticity or elasticity, such as a sponge, so as to have shrinkage and restoring force to improve airtightness and airtightness.

The sound insulation plate 231 is formed of a metal plate.

The soundproofing plate 231 includes at least a sound absorbing material for facilitating installation while effectively blocking noise emitted through the opening portion 1a of the building. The soundproofing plate 231 is made of a material having elasticity or elasticity, Egg-shaped sponge.

For example, when the soundproofing plate 231 has a laminated structure of a sound absorbing material and a sound insulating material, it is preferable that the sound insulating material is located inside the sound insulating plate 231 and a plurality of through holes are formed.

As shown in Fig. 4, the convex portion of the concavity 231a may be hemispherical. Further, it may be formed of any one of conical, triangular, rectangular, elliptical, trapezoidal, or rhombic. The concave portion of the unevenness 231a may have a circular or polygonal structure.
