The present invention relates to a method for constructing a noise inhibitor on a concrete wall of a building, and more specifically, to a building such as an apartment building and a building such as an apartment, such as a buffer, a sound insulation, a soundproofing agent, a filament, etc. In the construction of noise suppressant, water-based adhesive that is harmless to the human body and does not provide the cause of secondary environmental pollution is applied and dried on the concrete wall, and environmental hormones and pollutants harmful to human body are released by attaching the noise inhibitor. The present invention relates to a method of constructing a noise suppressant on a concrete wall of a building to allow construction of an eco-friendly building by removing a sick house syndrome.

In general, when constructing buildings such as apartment houses and buildings, it is mandatory to install noise suppressors such as sound insulation, sound insulation, and filaase, and these noise inhibitors are used to prevent floor noise as well as floors. From the wall to a wall of constant height.

That is, Figure 1 is a cross-sectional cross-sectional view of a typical building, after installing the wall noise suppressor (3) to the height of 5 ~ 11cm on the concrete wall (2), floor surface for minimizing the noise between the floor on the concrete floor (1) Install the noise suppressant (4).

Subsequently, the concrete and the foaming agent are mixed on the floor surface noise suppressant (4) installed on the bottom surface and poured into a predetermined thickness to form a buffer bubble layer (5), and heating of the buffer bubble layer (5) is completed at regular intervals. After the installation of the piping (7), by placing and curing concrete of a certain thickness on the upper surface of the heat distribution pipe (7) to complete the construction of each floor of the building through the process of forming the Excel and heating layer (6).

As described above, the one side of the wall noise suppressing agent 3 attached to the concrete wall surface 2 to absorb and block the noise with the wall is attached to one side of the wall noise suppressing agent 3 as shown in FIG. 2. The release paper 20 in which the oil-based adhesive bond layer 10 for fixing to the concrete wall surface 2 is formed is piled up.

The oil-based adhesive layer 10 formed on the release paper 20 when the combined release paper 20 is separated from the wall noise inhibitor 3 so as to install the wall noise inhibitor 3 configured as described above on the concrete wall 2. ) Is attached to the wall noise suppressant (3), and the transferred oil-based adhesive 10 is disposed so as to correspond to the concrete wall (2), when a certain pressure is applied to the concrete wall surface by the oil-based adhesive layer (10) It is fixedly attached to (2).

The release paper 20 is formed by coating the polyurethane grains on the paper 21 at a high temperature of 180 ° C. or higher as in FIGS. 3A and 3B to form a polyurethane coating layer 22, and then on the polyurethane coating layer 22. After the silicone resin is applied, the silicone resin is cured at a high temperature of 180 ° C. to form the silicone coating layer 23, thereby preparing the release paper 20, and then using an oil-based adhesive on the silicone coating layer 23 of the release paper 20 to 50 to 60 μm. After coating to a thickness and dried to form an oil-based adhesive layer 10, the oil-based adhesive layer 10 is configured to be combined so as to correspond to one side of the wall noise suppressant (3).

Here, the polyurethane coating layer 22 serves as a vinyl coating to prevent the silicon is absorbed into the paper, the silicone coating layer 23 is the oil-based adhesive layer 10 is attached to the wall noise suppressant (3) After performing the function of maintaining the release property so that the release paper 20 is easily peeled from the oil-based adhesive layer (10).

When the release paper 20 is peeled from the wall noise suppressing agent 3, it cannot be recycled due to the coating of polyurethane and cannot be recycled. Also, since the pollution is released during incineration, it must be incinerated in a licensed incinerator. Problems that cause environmental pollution are caused by the release of harmful substances to the human body from the polyurethane coating layer during the treatment, and high heat consumption of 180 ℃ or more is required to form the polyurethane coating layer 22 and the silicon coating layer 23 has a large fuel waste. There is a problem.

In addition, the oil-based adhesive layer 10 formed on one side of the release paper 20 and attached to the concrete wall 2 is composed of volatile organic compounds (TVOCs) containing toluene as a main component. After completing the construction of the building, it is not only a cause of sick house syndrome due to the release of environmental hormones, but also an irritating odor that affects blood vessels and nerves, causing neurological diseases and cancer. The trend is to restrict or prohibit its use.

The oil-based adhesive layer 10 is a phenomenon that the adhesion performance is significantly reduced to the fine particles of sand and cement distributed on the concrete wall (2), in particular the wall noise inhibitor (3) on the concrete wall (2) The construction period for constructing the floor noise suppression agent 4 in the attached state and forming the buffer bubble layer 5 takes about 1 day to 1 week depending on the construction area of the building, working conditions, and the like. Due to the deterioration of the adhesive performance, the wall noise suppressant (3) is easily detached from the concrete wall (2), and the work efficiency is significantly lowered, such as reattaching from time to time, resulting in a delay in the construction period. Problems that cause waste will occur.

Furthermore, the wall noise suppressant 3 requires a release paper 20 in which paper 21, a polyurethane coating layer 22, a silicone coating layer 23, and an oily adhesive layer 10 are sequentially stacked on one side thereof. Since the process of combining the release paper 20 and the wall noise suppressing agent 3 is required, not only is a factor of increasing the manufacturing cost, but it also causes a problem of increasing the construction cost of the entire building.

The present invention is harmless to the human body in order to solve all the above problems at once, does not provide the cause of the secondary environmental pollution, excellent adhesion and long-lasting water-based adhesives or rollers on the concrete wall to be installed noise suppressant Alternatively, when applied with a spray, the water-based adhesive is evenly distributed in the fine particles of sand and cement, and when the sound-proofing agent is installed on the applied water-based adhesive, the sound-proofing agent is firmly bonded by the strong adhesive force of the water-based adhesive. It is a technical problem to provide a method of constructing a noise suppressant for concrete walls.

When the noise inhibitor is installed on the concrete wall by this construction method, the paper, the polyurethane coating layer, the silicone coating layer, and the adhesive layer do not need a release paper formed by sequentially stacking, thereby preventing environmental pollution that may occur during incineration of the release paper. This eliminates the need for a combination of release paper and noise suppressant, which can significantly reduce the manufacturing cost of noise suppressants, which in turn can contribute to a reduction in construction costs.

In addition, when the noise inhibitor is installed on the concrete wall by the above construction method, the use of water-based adhesive does not cause harmful environmental hormones to the human body, and thus does not cause harmful effects to workers and residents, such as sick house syndrome, and especially for more than a week. If the noise inhibitor is installed on the concrete wall once, it eliminates the phenomenon of desorption, thereby improving workability and reducing manpower and construction costs due to the shortening of the construction period.

The present invention is a method of constructing a noise suppressant on a building wall to install a noise inhibitor such as a buffer, sound insulation, sound insulation, filament, etc. on the concrete wall, which is harmless to the human body and does not provide a cause of secondary environmental pollution. Aqueous adhesive coating step of applying a conventional aqueous adhesive to a thickness of 50 ~ 60um, a drying step of drying at room temperature for 15 minutes or more after the aqueous adhesive coating step, and attaching and fixing the noise inhibitor on the dried aqueous adhesive after the drying process Characterized in that it consists of a noise inhibitor attachment process.

Hereinafter, described in detail with reference to the accompanying Figure 4 the construction method of the noise inhibitor of the building concrete wall according to the present invention.

First, the present invention, the adhesive used to fix the wall noise inhibitor (3) to the concrete wall (2) is harmless to the human body does not provide a cause of secondary environmental pollution, excellent adhesion, long-lasting and commonly sold By using an aqueous adhesive, for example, it is marketed and sold by Macrosol Co., Ltd., for example, and an aqueous adhesive (product name: E101A) can be used.

The product name E101A sold by Macrosol Co., Ltd. is an acrylic ester whose main component is water, the main solvent is water, maintains a solid content of 66.3%, a viscosity of 4.570 CPS / 25 ° C, and a pH of 6.5 and does not release any environmental hormones. As the water-based adhesive, Korea Air Cleaning Association has obtained the certificate of eco-friendly building materials (certificate number: HB357E05-01) with the highest grade, and it is reported that the adhesive strength is excellent and the strong adhesive strength is maintained for more than a week.

In addition, the present invention is not limited to the use of environmentally friendly and harmless water-based adhesives, it can be selectively used according to the material of the wall noise inhibitor (3).

Figure 4 is a cross-sectional cross-sectional view of the concrete building constructed by the construction method according to the invention, the aqueous adhesive coating step of first applying a water-based adhesive 30 to the concrete wall (2) with a brush, roller or spray 50 ~ 60um thickness When the fine particles of sand and cement absorb some of the aqueous adhesive 30, a part of the surface of the concrete wall 2 is coated with the aqueous adhesive 30.

In this case, when the aqueous adhesive 30 is applied to a thickness of 50 μm or less, since the fine particles of sand and cement do not sufficiently absorb the aqueous adhesive 30, the coating layer is not uniformly formed, and thus the adhesive force is lowered. When the aqueous adhesive 30 is applied to 60um or more, the coating layer is formed to be thick, so that the adhesive force is lowered, which is preferably applied to a thickness of 50 to 60um.

When the aqueous adhesive coating process is completed, a drying process of drying at least 15 minutes at room temperature is performed, and the moisture contained in the aqueous adhesive 30 is evaporated by this drying process to perform a function as an adhesive.

In the case where the aqueous adhesive 30 applied to the concrete wall surface 2 is dried for 15 minutes or less, it is preferable to dry for 15 minutes or more because sufficient moisture is not evaporated to the extent that the adhesive function can be obtained.

When the drying process is completed, when the sound-proofing agent attaching process of attaching and fixing one side of the wall noise-preventing agent 3 on the water-based adhesive 30 is performed, the wall noise-preventing agent 3 is formed by the strong adhesive force of the water-based adhesive 30. It is firmly fixed and adhered to the concrete wall surface 2.

Here, the water-based adhesive 30 applied to the concrete wall 2 is maintained for more than one week, so applying artificial force to the wall noise suppressor 3 as necessary, so that the wall noise inhibitor 3 can be detached from time to time. It can provide a very convenient advantage.

As described above, the present invention eliminates the phenomenon of sick house syndrome by preventing the release of environmental hormones and pollutants harmful to the human body by using an aqueous adhesive, and thus does not harm workers and residents, and constructs an environment-friendly building. In addition to maintaining strong adhesion for more than a week, the noise reduction agent once installed on the concrete surface eliminates the phenomenon of detachment unless artificial force is applied, thereby improving workability and reducing manpower and It is effective in reducing construction costs.

In addition, the present invention is harmless to the human body does not provide a cause of secondary environmental pollution, and after applying a water-based adhesive with excellent adhesion and long-lasting water-based adhesive partially on the concrete surface to be installed, the noise suppressant by installing a noise inhibitor Paper, a polyurethane coating layer, a silicone coating layer, an adhesive layer is laminated on one side of the surface is not necessary to release the release paper is made that there is an effect that can contribute to the prevention of environmental pollution and manufacturing costs.
