Will not touch each other, short circuits, short circuits and The present invention relates to a noise preventing floor construction method of a multi-unit building to prevent a fire caused by an arc.

In recent years, the strife between the upper and lower floors due to the noise between floors of apartments has often been invented, and the dispute is gradually becoming a serious social problem.

The noise between floors is mainly made of reinforced concrete, which is generated by the sound of footsteps or movement of doors and moving doors and the impact of furniture and appliances, impacts on floors, children running and rolling, etc. This is because the floor slab (downstair ceiling slab) and the wall are transferred to the lower floor living space.

Construction methods of various kinds of floor noise prevention flooring materials have been developed to solve the noise problem of the multi-family house.

As a related art, Korean Registered Patent No. 10-0634429 (registered on October 09, 2006) "Interlayer flooring and dry floor construction method using the same" (hereinafter referred to as 'prior art 1') is installed on the upper surface of the slab of a building. In the interlayer flooring material; The noise buffer mat placed on the bottom surface of the slab as the interlayer floor material is a high temperature and compression molding by stirring a moisture-curable polyurethane-based one-component adhesive on the EVA chip at a ratio of 15: 1, and pipes the heating pipe on the noise buffer mat. After fixing with stone powder, the upper mat constructed on top of the powder powder contains 1 part of a latex mixture containing 50% of water and 50% of a latex mixture composed of 26% latex, 73.97% diluent, 0.01% ammonia, and 0.02% chlorine. Lant Class 1 A mixture of 27% cement, 14.5% of high strength mixture for steam curing, 47.9% of No. 3 silica sand, 10.5% of pearlite, and 0.1% of fiber was mixed and mixed in 4.5 parts by weight, and then dried in a drying furnace for 4 hours at a temperature of 60 to 80 ° C. Manufactured by fast drying, it is possible to dry construction without placing concrete in the field when constructing floor materials of apartment houses, and to minimize noise and vibration transmission between floors. It discloses a technique.

In addition, the Republic of Korea Patent No. 10-1565049 (registered October 27, 2016) "sound insulation interlayer flooring" (hereinafter referred to as "prior art 2") is the first sound insulation material formed in a flat plate from the top, a plurality of pressure And a second sound insulation material having a plurality of irregularities including recesses corresponding to the ventilation holes of the film paper, and the pressure generated in the second layer by the primary sound insulation material. Absorbed, the impact sound applied to the primary sound insulating material is secondarily absorbed in the plurality of pressure holes formed in the pressure-dispersion sound insulating material, the remaining impact sound and pressure is a groove forming a concave-convex formed in the secondary sound insulating material through a plurality of ventilation holes formed in the film And the impact sound dispersed in the third sound absorbing material by the second sound insulating material may be prevented from being transmitted to the lower layer. The disclosed technique is disclosed.

However, the prior arts 1 and 2 are installed between the slab and the cement mortar, the cement mortar is installed with the edges in close contact with the sidewalls, and the sidewalls are integrally installed with the slab, where shock and vibration are started. In view of the fact that it is a mint mortar, the impact and vibration generated in the second layer is transmitted from the cement malta to the side wall, and from the side wall to the lower layer through the slab, there is a problem that the effect of reducing the interlayer noise is reduced.

In addition, a floor covering such as a floor covering is installed on the upper surface of the cement mortar, and a wallpaper is installed on the side wall, and a baseboard is installed between the edge of the flooring and the bottom of the wallpaper.

Conventional clothes racks typically protrude about 1 cm from the wall, so the furniture cannot be mounted firmly on the wall when the furniture is mounted. There is a problem that becomes cumbersome.

In general, in the construction of the wallpaper, the wall is glued to the wall with grass, and the bottom part of the wallpaper is folded and glued to the top of the base of the cloth, which is usually made of synthetic resin or wood. As the grass dries, the lower end of the wallpaper, which is glued to the top surface of the baseboard, falls off, thereby degrading the interior aesthetics.

In addition, a wall outlet is installed to connect power cords of various home appliances. Since the power cord connected to the outlet is exposed as it is, the power cord may cause interference when cleaning or moving furniture, etc. There is a problem.

In addition, when the sound insulation material is made of urethane rubber material, the cushioning and sound insulation effect is exerted, but there is a problem in that the home appliances and furniture are not firmly and stably mounted when the home appliances and furniture are provided thereon.

In addition, the Republic of Korea Patent No. 10-1859577 (announced on May 21, 2018) as the prior art "Mountain floor construction structure to prevent noise between floors" (hereinafter referred to as "prior art 3") is buried at the bottom of the wall and the bottom sound insulation material , The sound insulation material, the top sound insulation material and the wall sound insulation material located between the edge of the cement mortar and the wall, and the impact and vibration originating from the flooring material are not directly transmitted to the wall through the cement mortar to which the flooring is attached, and formed integrally with the wall. By not transmitting to the slab, the noise reduction effect between floors can be increased, and the baseboard is not protruded from the wall, so the furniture can be mounted firmly and conveniently. Make sure that it is mounted securely and securely, and that the power cord to the wall outlet is not exposed to the outside. When positioning such as cleaning or household will have the power cord to avoid causing interference.

On the other hand, in the construction of a multi-unit house, assembling the lower wall formwork and the upper slab formwork, reinforcing the reinforcing bar and then injecting concrete so that the lower wall and the upper floor slab can be poured at the same time.

The prior art 3 assembles the wall formwork while fixing the wall insulation material to the wall formwork in the process of constructing the wall and the floor slab in the above-described manner, and when concrete is injected, it is possible to pour the wall embedded with the wall sound insulation material.

However, in the prior art 3, the wall sound insulation material body and the base plate body and the base plate cover are integrally connected by the rotation connection piece, and the wall sound insulation material is formed on the wall soundproof material because the rotation connection piece protrudes from the interior side of the wall sound insulation material body and the base plate cover. When fixing to the formwork there is a problem that the wall sound insulation material is not buried as designed on the wall because the interior side of the wall sound insulation body and the base cover is not fixed to the wall formwork as much as the protrusion height of the rotation connection piece is fixed in the excited state.

In addition, the prior art 3 is a wall sound insulating material formed of urethane rubber material by the concrete placing pressure because the cord clearance space is formed between the base and the base cover when the concrete is placed while fixing the wall sound insulating material to the formwork There is a problem that can not be maintained in the designed form, such as the main body of the base plate is pressed and crushed, so that the function as a wall sound insulation material and the code arrangement function can not be exhibited.

In addition, the power cords stored in the cord clearance space of the wall sound insulation material are simply stored without fixing or supporting means, so that the power cords of several strands come into contact with each other, and there is a risk of fire due to short circuits, short circuits, and arcs. have.

In addition, since the edges of the lower sound insulation material, the interrupted sound insulation material and the upper sound insulation material are simply abutted on the interior side of the wall sound insulation material body, the wall sound insulation material, the lower sound insulation material, the interrupted sound insulation material, and the upper sound insulation material have a problem that the sound insulation effect is degraded. .
