BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wall construction method for reducing vibration noise transmitted through a wall, and more particularly, The present invention relates to a method of constructing a wall in which vibration noise transmitted through a wall and air transmission noise are greatly reduced due to the joining of members.

As the lives of ordinary people are getting richer, housing is required not only for residential purposes but also for a more comfortable living environment. However, residents of apartment houses and multi-family houses in ever-increasing trends, I can not solve my own desire to make a sound freely. Prevention of noise generated in the interlayer is recognized as the first requirement of a comfortable living environment. Therefore, construction companies are also raising various efforts for the development of anti-noise materials to satisfy the needs of actual users.

Particularly, in the reinforced concrete ramen structure, the noise and vibration of the upper generation are greatly reduced through beams and columns. In many cases, noise is transmitted to the side generation through the partition wall installed at the lower part of the beam. This is caused by the fact that the boundary wall installed at the lower part of the beam is not airtightly installed or poorly installed.

In addition, noise and vibration are often transmitted through a boundary wall within a generation that is formed under the upper slab in one generation.

In other words, modern society is a shared economy era, and the frequency with which two families or people live together in a generation is gradually increasing. In this way, when a person shares a generation, it is necessary to secure the privacy of the inner wall of the household as well as the barrier within the household.

However, when the unit residence is composed of two stories, the impact sound transmitted to the upper and lower generations is reduced, but the horizontal distance between the generations is shortened so that the impact sound transmitted in the horizontal direction is not changed. In order to reduce the horizontal impact sound generated when the unit residence is composed of two layers, the generation slab should be separated from the side wall shared with the neighboring household so that the impact sound is not transmitted in the horizontal direction. However, the structure for separating the slab from the side wall can be variously designed in the mid- and low-rise structure without a big problem, but there is a limit in that the high-rise structure can cause structural coupling due to structural stiffness and earthquake.

Therefore, it is necessary to develop a technology to fundamentally block or reduce the noise vibrations generated between adjacent houses or between adjacent houses in a house.

Registered Patent No. 10-1679672 ("Design structure of a multi-storey apartment house with reduced floor noise and a safe evacuation route in case of fire")

In order to solve the above-described problems, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a reinforced concrete rail structure in which a gap between a beam and a boundary wall is airtightly installed, So as to reduce vibration and impact transmitted to the lower partition wall through the beams.

In addition, vibration absorbing members or the like are buried and installed in the lower part of the upper slab forming the boundary wall in the same household to reduce vibrations and shock transmitted through the partition wall in the household, and to reduce the air transmission noise through the non- For other purposes.

The present invention is also directed to a method of constructing a wall for reducing vibration noise, characterized in that the first to seventh steps are applied to a column or a retaining wall that meets orthogonally with the beam or slab.

According to the present invention, in a reinforced concrete ramen structure, airtightly installed between a beam and a boundary wall installed between adjacent unit generations to prevent transmission of noise between left and right generations and to prevent vibration and shock transmitted to the lower boundary wall through beams, Conflicts between neighbors can be solved.

In addition, it is possible to minimize the damage caused by noise and vibration even within a generation by securing the barrier within the household even within one generation, thereby securing privacy.

In addition, since the vibration absorbing member is embedded and installed in the beam and the slab, the vibration and noise reduction effect can be maximized.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a wall for reducing vibrations transmitted from a boundary wall inside a neighboring household or a household and noise caused thereby.

Specifically, the present invention provides a method of constructing a wall for reducing noise transmitted through a wall formed by a beam or a slab bottom, comprising the steps of: providing a mold (F) for forming beams or slabs; A second step in which the body part 100 formed in a hat-shaped cross section and the absorber 200 are sequentially engaged with each other while being abutted on the lower surface of the mold F; A third step of fixing the end of the body part 100 and the end of the shock absorber 200 to the lower surface of the mold F with a sealant S; A fourth step of pouring concrete into the mold F and disassembling the mold F after curing; A fifth step of providing an upper runner 300 on the lower portion of the body 100 and a lower runner 400 on a bottom surface corresponding to the upper runner 300 and then coupling the stud 500; A sixth step of inserting a sound absorbing material 600 between the studs 500 and coupling a finishing member 700 to the outer surface of the stud 500; And a seventh step of filling the cushioning material 800 between the closure member 700 and the body part 100.

The first step is to install a mold (F) for forming a concrete casting frame to form a beam as a structure for conveying an upper load or a slab forming a bottom of a user.

The second step is to install the body 100 and the absorber 200 on the lower surface of the mold F installed to form beams or slabs. At this time, the body part 100 and the absorber 200 are installed at positions corresponding to the upper part of the wall forming the boundary in the next generation or one generation. After installing the form F of the first step, do.

The body part 100 is a member which is engaged with the upper part of the lower surface of the form F, and is formed as a hat-shape as a whole. More specifically, as shown in FIG. 2A, both ends of the '┏┓' cross section are horizontally extended in the orthogonal direction. At this time, the body part 100 can be fixed to the lower surface of the form F by the fixed hardware 120 which is inserted through the lower end of the form F as shown in FIG. 1A. That is, a bolt-type fixing hardware 120 is inserted from the outer surface of the mold F so as to penetrate through the horizontally extended portion of the body 100 to firmly fix the body 100 to the lower surface of the mold F do. Also, it is preferable that the body portion 100 is formed of a galvanized member on a steel plate, thereby satisfying durability and corrosion resistance.

The shock absorber 200 is a member corresponding to the body 100 and coupled to the outer surface of the body 100. That is, the shock absorber 200 is coupled in a form to enclose the body portion 100 coupled to the lower surface of the form F. When the concrete is poured into the form F, the body 100 is cured, do. The absorber 200 is preferably made of rubber or styrofoam, which absorbs and reduces vibration noise transmitted from the adjacent household or room through the wall.

In the third step, the body 100 and the absorber 200 are coupled to the lower surface of the form F, and the end of the body 100 is sealed. For example, after the mold (F) is installed, the body 100 and the absorber 200 are connected to each other by the fixed hardware 120, and the end of the absorber 200 is closed with a material such as silicone. This not only keeps the noise vibration transmitted through the gap between the body part 100 and the lower surface of the mold F, but also prevents it from flowing into the gap when the concrete is poured. Therefore, it plays a role of preventing vibration noise reduction effect as well as building construction defects.

In the fourth step, as shown in FIG. 1B, after the body 100 and the absorber 200 are coupled to each other in the form F, the curing time of a certain period passes after the concrete is poured and the mold F is demolded to be. When the lower surface of the form F is demolded, the '┏┓' side end face of the body 100 is exposed, and one side of the beam or slab is recessed along the longitudinal direction when viewed from the bottom.

In the fifth step, the upper runner 300 is installed on the body 100, the lower runner 400 is installed on the floor corresponding to the upper runner 300, the stud 500 is installed between the upper runner 300 and the lower runner 400, As shown in FIG. At this time, the upper runner 300 may be installed on one side of the body portion 100 exposed downward after the form F is demolded, and the lower runner 400 may be installed on the bottom surface of the lower slab.

In the sixth step, the sound absorbing material 600 is inserted between the studs 500 installed in the fifth step and the closure member 700 is coupled to the outer surface of the stud 500.

The sound absorbing material 600 preferably has insulation performance as well as sound absorbing performance so as to prevent noise vibrations from being transmitted between adjacent left and right generations. For example, a glass wool or the like may be used.

The finishing member 700 forms a finishing surface of a wall inside the house, and various materials such as a gypsum board and a CRC board may be used, and the outer surface of the finishing member 700 may be finished with paint or wallpaper.

The seventh step is to fill the space between the top runner 300, the stud 500 and the closure member 700 coupled to the inner surface of the body 100 with the side surface of the body 100 with the cushioning material 800 . When the closure member 700 is coupled to the outer surface of the stud 500, a gap is formed between the upper portion of the closure member 700 and the inside of the body 100, and filling the space between the closure member 800 and the closure member 800. For example, urethane may be filled between the closure member 700 and the inside of the body 100, and the lower end may be treated with silicone. That is, a process of filling the urethane with the finishing member 700 and the upper surface of the body 100, and sealing the same with the sealant S so as to be finished in line with the lower end of the beam or slab. As a result, vibration noise transmitted from an adjacent household is blocked by the damping material 800, so that a dispute due to noise among neighbors can be solved.

Meanwhile, the first to seventh steps of the present invention can be applied to a column or a retaining wall that meets orthogonally with a beam or a slab. An example of this is shown in Figures 3A-3C.

3A is an embodiment in which the body 100 and the absorber 200 are installed in a beam lower part, and is effective in reducing vibration noise among neighboring generations in a reinforced concrete ramen structure. Especially, it is advantageous to apply to the multi-storey apartment house where the upper story is the living room and the lower story is the bedroom. This effectively prevents the noise of the living room where the noise is generated from being transmitted to the bedroom of the lower generation. This is because the vibration noise transmitted through the structure is integrated with the wall formed at the bottom of the beam, and a plurality of sound absorbing members such as the shock absorber 200 and the shock absorber 800 are combined.

FIGS. 3B and 3C show an embodiment in which the body 100 and the absorber 200 are installed in the lower part of the slab, and it is advantageous to be applied to the inner wall of the house irrespective of the wall structure or the ramen structure. 3B shows a structure in which the body 100 is installed inside the structure when the thickness of the structure is thick, and FIG. 3C shows a structure where the structure is protruded to the bottom of the slab when the thickness of the structure is thin. A framework should be set up for
