The present invention relates to the floor and the construction technology of apartments such as apartments and villas, and more specifically, divided into a plurality of (3 to 5) independent floors according to the interior structure of the apartment house, at the same time, the floor Independent / double for reducing noise between floors of walled apartment houses, which has a better floor-to-noise structure, by forming a double-floored floor divided into a certain area in the center of the independent floor of a living room or a room with a wide span. It relates to a floating floor and its construction method.

In general, an interlayer floor for reducing the noise between floors of a conventional MDU usually has a floor cushioning material having a thickness of 10 to 20 mm on a concrete slab of one generation, and the wall concrete (gypsum board attachment surface, balcony window frame, etc.) contacting the concrete slab. It is well known that wall insulation materials of 5 ~ 10mm thickness are attached to the finishing mortar (or around 10mm) to block vibration or noise transmitted to the upper and lower floors through the floor or wall of the apartment house. It is true.

However, even when the floor cushioning material and the wall insulation material are installed in the concrete slab and the wall concrete, the impact bubble or vibration generated from one side of the floor is not generated because the lightweight foamed concrete and the finishing mortar installed thereon are installed in a single structure for the whole generation. There is a problem of spreading to the whole and delivered to the upper and lower layers.

Such problems include not only the thickness, density, and stiffness of concrete slabs, but also the density, thickness, and spring coefficient of the floor buffers installed thereon, and the thickness, density, and overall size and mass of lightweight foam concrete and finishing mortar on the floor buffers. The basis of the difference in vibration transmittance between the impact forces of the impact and the acoustic propagation theory in which the loudness of the sound depends is thus confirmed.

In other words, the size of the whole household is usually 70 m 2 or more (in case of pre-equilibrium 32 pyeong), and consequently, not only forms an interlayer floor, but also has a structure such as a gypsum board attaching surface, a balcony window frame, or the bottom of a door frame. There is a problem that the wall insulation material is not attached to the part, and even when installing the heating pipe, there is a problem that the sound bridge phenomenon occurs around the pipe due to insufficient treatment for the dust.

Moreover, in addition to the above problems, most of the multi-unit houses that are currently constructed or constructed are wall-type, that is, the floor and walls of the entire generation of multi-unit houses are integrally connected. When the floor noise is measured in an apartment with a wall structure, it is noted that even if the thickness of the concrete slab is 150 to 200 mm or more than 240 mm, the difference in impact sound detected in the upper and lower layers is only 2 to 3 dB. This can be confirmed in detail from the facts.

In particular, the preference for large apartments is increasing due to the improvement of income level, and the indoor floor space for each household is expanding. Accordingly, the width of the main room or living room, which is the main activity area, is gradually increasing.

Therefore, when the impact occurs in the middle point of the living room or the inner room consisting of a large flat water as described above, the ringing phenomenon of the floor structure acts greatly, and the transmission of the upper and lower layers of the vibration or impact sound occurs more than anywhere else. This can be clearly seen from the difference between the noise level at the center of the living room and the noise level at the center of the living room, i.e., near the wall, when the actual floor impact sound is measured.

In addition, when a defect such as cracks or breakage occurs in the lightweight foam concrete that is placed on the floor cushioning material having the buffering performance, as a countermeasure, by placing a high strength lightweight foam concrete with a high specific gravity of the foam foam As a result, the thermal insulation performance is lowered as well as the absorption of impact energy is significantly lowered. In addition, focusing on workability when placing finishing mortar, as the finishing mortar slurry with too high W / C is poured, lightweight foam concrete absorbs excessive moisture of the finishing mortar, weakening the thermal insulation of light foam concrete and impacting it. The surface density is greatly reduced along with a decrease in energy absorption performance, cracking and finishing of mortar. In addition, when constructing ondol floor, not only the horizontal smoothness of the finishing mortar is low, but also the gap between ondol floor and finishing mortar occurs due to the adhesive construction with most epoxy bonds due to excessive product and construction price competition. As a result, several problems are pointed out such that the impact energy of the ondol floor is transmitted to the finishing mortar as it is.

Accordingly, in the multi-family housing, such as apartments and town houses, there is an urgent need for a technology to more effectively block the transmission of shock sounds and vibrations and to reduce noise generated between floors.

Therefore, the present invention has been made to solve the above problems and drawbacks, the main purpose is to divide the single floating floor of the wall-type apartment house, such as apartments and villas into a plurality of independent floating floors according to the interior structure At the same time, by forming a double-floored floor hole divided into a certain area in the center of the independent floor of a living room or a room with a large span of the floor, it is possible to reduce the noise between floors of a wall-type apartment house that has a better floor-to-noise structure. The purpose is to provide freestanding / double floating floors and their construction methods.

Another object of the present invention is to form a double-floated floor, yet another auxiliary thickness of about 50 to 75% of the thickness of the floor buffer material therein in order to minimize the transfer between the upper and lower layers to the vibration or impact sound generated therein The purpose of the present invention is to provide an independent / double-floored floor and a construction method thereof for reducing the noise between floors of a wall-type multi-family house in which a cushioning material is constructed.

The purpose of this study is to provide independent / double floated floors and construction methods for reducing floor noise.

Furthermore, the present invention is to form the respective expansion joints for constituting a plurality of partitioned independent floating floors and double floating floors according to the interior structure of the multi-unit house, the lower expansion joint and heating piping installed at the height of lightweight foam concrete It is composed of upper expansion joint installed at the height of finishing mortar, including the floor floor noise of the wall-type apartment house that is attenuated by sequentially passing the divided components such as ondol floor, finishing mortar, lightweight foam concrete, and floor buffer when impact sound occurs.

1 to 6, in the interlayer floor structure of a multi-family house having a wall structure in which the concrete slab 1 and the wall concrete 2 are integrally formed, on the concrete slab 1, as shown in FIGS. The interlayer floor structure of each generation constructed in the form of floating floor is partitioned and divided into a plurality of independent floating floors 100 using the wall insulation material 5 and the expansion joints 10 and 20, and a span with a relatively wide span. In the center of the living room and the like to form a double floating floor structure 200 partitioned into a predetermined space.

Thus, on the concrete slab 1, the floor cushioning material 4 for interlayer insulation and noise reduction is constructed so that the lightweight foamed concrete 6 and the finishing mortar 8 which are poured on the upper part from the concrete slab 1 are separated from each other. The floor buffer material 4 is formed with a thickness of at least 20 mm as a product having an elastic modulus and a loss factor of a predetermined value or less and a thermal conductivity of a predetermined value or less.

Therefore, the concave-convex parts such as cement slurry or nail on the concrete slab 1 are removed as close as possible to the wall side, and the construction of the pipes in close contact with each other prevents sonic phenomena through the pipes. Adhesive tape is attached between the cushioning material 4 to form a waterproof layer.

The lower inner surface of the wall concrete (2) is attached to the wall insulating material (5) for insulation between layers and noise reduction, the lightweight foamed concrete (6) and the finishing mortar (8) which is poured therein from the wall concrete (2) is separated The wall insulating material 5 is formed with a thickness of at least 10 mm as a product having an elasticity coefficient and a loss coefficient of a predetermined value or less and a thermal conductivity of a predetermined value or less.

In this case, the wall insulating material 5 is disposed on both sides of the lower side of the interior wall 3, gypsum board board and balcony window frame (hereinafter referred to as interior wall), which divides the interior into a plurality of spaces in addition to the wall concrete 2. The various pipes attached and started from the wall surface are closely adhered to the buffer tape 50 to prevent the vocal phenomena through the pipes.

Therefore, the concave and convex parts such as dust, slurry, or nails attached to the lower side of the wall concrete 2 or the interior wall 3 are removed in a state where they are cleanly removed using adhesive, and the various pipes starting from the wall are buffered. The tape 50 is tightly wrapped to prevent sonic phenomena generated through the portion.

The expansion joints 10 and 20 are for partitioning a single floated floor connected between the respective interior walls 3 into a plurality of independent floated floors 100, and having a modulus of elasticity equal to or less than a predetermined value absorbing vibration energy. It is formed of a synthetic resin material having a heat resistance of a predetermined value or more for the heating pipe and is installed on the floor buffer 6 in a state of being connected to the wall insulating material 5. That is, where the wall insulation material 4 is not installed, the expansion joints 10 and 20 are installed in the lower part of the door frame leading to each room or the passage leading to the living room and the kitchen. To form the floated floor (100).

In addition, a small double floated floor 200 having a predetermined space is formed in the inner center of the inner room or living room partitioned by the independent floated floor 100 by using expansion joints 10 and 20. By intercepting the impact sound or vibration generated in the center of the room or the living room with a relatively large span is transferred to the independent floor 100 inside the double floated floor 200 to improve the effect of interlayer vibration.

Therefore, the formation size of the double floated floor 200 is most preferably formed by 25 to 30% of the corresponding independent floated floor 100. First, independent walls of four sides or sides are formed on the center of the floor where the inner and living rooms are formed. Lines are drawn at positions spaced apart from the expansion joints 10 and 20 for partitioning the floor 100, and then the expansion joints 10 and 20 are attached to the floor buffer 4 on all sides. Construct in a sealed state.

The expansion joints 10 and 20 constructed as described above may be formed to the height of the finishing mortar 8 including the lightweight foam concrete 6, but the lower expansion for partitioning the lightweight foam concrete 6 It is preferred that the construction is partitioned with an upper expansion joint 20 for partitioning the joint 10 and the finishing mortar 8 poured thereon.

At this time, the lower expansion joint 10 is formed in a plate shape having a thickness of 25mm is attached to the bottom buffer 4, the height of the lower expansion joint 10 to the lightweight foam concrete 6 to be poured Construct until. Subsequently, the upper expansion joint 20 is formed in a plate shape having a thickness of 15 mm and is attached to the upper end of the lower expansion joint 10. The heating piping 7 installed therein and the finishing mortar 8 disposed thereon are installed. The construction to the height of the upper expansion joint 20.

Thus, when installing the expansion joints (10, 20) for forming the double-floor floor 200, both side wall concrete (2) opposed to display the height of the lightweight foam concrete (6) and the finishing mortar (8) Or a plurality of upper and lower level bars are installed at about 2m intervals with respect to the interior wall 3, the lower expansion joint 10 adheres the lower end onto the floor buffer 4, and Both sides are fixed by attaching the bottom buffer material 4 and the adhesive tape 12, and the upper end thereof is fixed to the lower level bar 30 to be fixedly installed.

Subsequently, after installing the lower expansion joint 10, the upper expansion joint 20 is installed at the upper end of the lower expansion joint 10 in the state in which the lightweight foam concrete 6 is poured and cured. After adhering the upper expansion joint 20 to the pension joint 10 using an adhesive, and then fixed by fixing a plurality of fixing pins 22 at regular intervals with the lower expansion joint 10, the upper end 2 is installed and the finishing mortar 8 of the heating pipe 7 in a fixed installation state leaning against the upper level bar (30).

On the other hand, the interior of the expansion joint (10, 20) installed to form the double-floor bottom 200 by attaching a secondary buffer 14 made of a thickness of 50 to 75% of the floor buffer (4) , The impact sound generated from the double floated floor 200 is prevented from being transmitted to the upper and lower layers more effectively.

In addition, after pouring and curing the light-foamed concrete (6), when the heating pipe (7) is constructed, the heating pipe (7) is constructed by minimizing the contact surface passing through the upper expansion joint (20).

That is, in each independent / double floated floor 100 and 200 partitioned by the upper expansion joint 20, a heating pipe 7 is disposed to be formed so as not to pass through several times except for a pair of inlets, and the upper expansion A buffer tape 50 is attached to the periphery of the pair of heating pipes 7 passing through the inlet of the pension joint 20 to block the vocal phenomena of the heating pipe 7 and at the same time, each independent / double floated floor ( Ensure complete compartments of 100, 200).

After pouring the finishing mortar 8 on the heating pipe 7 thus constructed, the exposed upper expansion joint 20 or the wall insulating material 5 is cut off, and then a surface hardening agent 42 is applied thereon. By using the upper expansion joint 20 as a medium, the heat of the heating pipe does not heat the surroundings, and by treating the entire surface of the finishing mortar 8 to which the surface hardener 42 is applied, the self-leveling agent 40 is treated. It has a horizontal surface and forms a thin film layer preventing cracks.

Therefore, according to the interlayer floor structure of the wall-type multi-family house, the impact sound generated at one point by each independent / double floated floor 100 and 200 is prevented from being transmitted to the neighboring independent / double floated floor 100 and 200. In addition, by blocking the pedagogical phenomenon caused by the impact sound generated in the center of the room or living room with a wide span, the vibration-proof soundproofing effect in the generation as well as the inter-layer dustproof soundproofing effect are further improved.

In addition, in the interlayer noise reduction structure, by applying a self-leveling agent 40 on the surface of the finishing mortar 8, which is the final finishing material layer, the horizontal smoothness is increased, thereby reducing the impact energy that can be primarily generated in the ondol floor 9, Finishing mortar (8) including lightweight foamed concrete (6) and heating piping (7) of independent / double floated floors (100, 200), each independently separated by the configuration of each of the upper and lower extension joints (10, 20) By the second and third lanes, respectively, noise and dust reduction are generated, and finally, the quadruple reduction structure is reduced to fourth by floor buffers.

On the other hand, the lightweight foam concrete (6) that is poured when forming the interlayer floor of the present invention constructed in such a way is in the applicant's patent application (patent application 2003-0039803, a method for producing lightweight foam concrete composition for crack prevention) As provided by the present invention, as well as excellent thermal insulation performance and crack prevention, it is poured using a mixture of a large amount of EVA synthetic resin crushing chip to be excellent in absorbing and buffering the impact energy when the impact occurs.

In addition, the finishing mortar 8 to be poured is provided by the applicant's utility model registration (utility model registration No. 0287084, inter-floor insulation and noise prevention floating floor structure), the latent heat performance and crack prevention performance Gravel the gravel to the height of the heating pipe (7) so as to excel.

Ondol floors with sound insulation sheets with excellent effects or sound insulation sheets are laid on the finishing mortar, and then ondol floors are installed on them. At this time, when the ondol floor 9 is adhered, a strong harmless adhesive material 50 is used to adhere the spots (radius of about 10 mm) or in a straight form (about 10 mm in width) to minimize sonic phenomena.
