The present invention is a construction method and structure to compensate for the shortcomings caused by the weight and excess weight of the material has a conventional floor heating method, the extension of the construction period, more specifically, the wet method by the foam concrete method is excessive weight Due to various disadvantages such as the risk of water leakage, prolonged construction period, and sound insulation and poor insulation, it is easy to apply to high-rise buildings. The structure relates to forming a first air layer by using an elastic support portion first, and forming a second air layer by using unevenness in which the upper and lower surfaces are alternately opened in a second manner, thereby making the bottom double and heavy and soft. Heavy impact sound that occurs when objects fall, as well as when light and hard objects fall It relates to a completely dry structure between floors of multi-unit houses that effectively blocks all of the light impact sounds.

In general, multi-unit buildings such as apartments or villas are designed to prevent noise between floors and floors so that each occupant's life can be protected from noise by preventing shock or noise generated between floors from being transmitted to the lower or upper floors. It is well known that technology is becoming common.

As described above, a technique for preventing interlayer noise includes noise or impact sounds generated between floors through an interlayer floor structure for preventing transmission of interlayer noise and impact sounds to Utility Model Registration Nos. 287084, 290830, and 297962. Techniques have been proposed to significantly reduce the transmission to the upper layer along this lower layer or wall, but these techniques are interlayered due to adverse reactions between the finishing mortar layer and the flooring (hardwood or marble, etc.) installed thereon. There was a problem that the noise is further amplified.

That is, the currently proposed technique to prevent the interlayer noise is to reduce and block the interlayer noise through the dustproof and soundproof structure from the concrete slab layer to the finished mortar layer. However, the impact or noise generated when the topmost floor mortar layer of the floor structure and the flooring material (such as hard floor or marble) finally installed on each other are amplified and transmitted to the room or the lower floor.

In addition, the finishing mortar layer is excessive in the amount and weight of the material, the construction period is very long or often extended depending on the weather or weather.

In addition, in the interlayer floor structure, because the finishing mortar layer is uneven plaster smoothness is somewhat bent and vertical deviation occurs, there is a problem that a floating phenomenon occurs when installing a hard floor or marble flooring. Therefore, as well as the impact and noise generated by the lifting phenomenon, cracks or damage to the flooring is frequently generated.

In addition, if only the flooring material is installed on the finishing mortar layer, the hard impact of the flooring material and the finishing mortar layer is transmitted directly to the body through the foot when running or walking indoors. There is a problem that can put pressure.

In addition, the conventional dry panel is not configured to support the load on each of the edge and the center portion, which is a structure that expands and contracts in response to the upper pressure, resulting in the walking feeling is reduced, there is also a problem that noise is generated.

Finally, according to such a floor structure, the construction period is too long, there is a difficulty in removing the entire floor structure when attempting to repair or remodel after the construction is made.

Accordingly, the present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to be able to construct even in a high-rise building, to provide a complete dry structure between floors of a multi-family house easy to repair after construction. It is.

Another object of the present invention is to increase the noise absorption rate for the noise between floors, to provide a completely dry structure between floors of multi-unit houses having a multi-structure that blocks not only heavy impact sound but also light impact sound.

Another object of the present invention is to reduce the weight and weight of the material by using a fully dry prefabricated inorganic board to reduce the manpower required for construction, minimize the construction period, the construction of a multi-family house that can be built regardless of season To provide a completely dry structure between the floors.

Still another object of the present invention is to provide a completely dry structure between floors of a multi-family house in which the thickness of the floor structure is not thick but the floor structure is not lifted.

Still another object of the present invention is to provide a completely dry structure between floors of a multi-family house, which constitutes a support part on one side of a dry panel and a central part of the dry panel to solve a poor walking comfort of the upper finish material, which was the biggest disadvantage of the existing completely dry structure.

Still another object of the present invention is to provide a completely dry structure between floors of a multi-family house that blocks shocks and noises transmitted through walls as well as floors.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the complete dry floor structure of a multi-family house according to the present invention having the configuration as described above will be described in detail.

As shown in FIGS. 1 and 2, the floor-to-wall complete dry structure 100 of the multi-unit house according to the present invention includes a floor slab 102 forming a floor of a residential building, and a floor above the floor slab 102. Horizontal pulp material 103 to enhance the smoothness of the plurality, a plurality of elastic support portion 110 is installed on the upper portion of the horizontal pulp material 103 at a predetermined interval to form a first air layer 104, and the elastic support portion ( A hard first inorganic substrate 120 supported by 110, a soft dry panel lower portion 130 stacked on an upper portion of the first inorganic substrate 120, and a lower portion of the dry panel A dry panel 140 stacked on top of the 130 to form a second air layer 134, a soft sound insulation pad 150 stacked on top of the dry panel 140, and the sound insulation pad A hard second inorganic substrate 120 installed on an upper portion of the 150 and an upper portion of the second inorganic substrate 160 It is configured to include a finishing material 170 is deposited.

The side surface of the interlayer completely dry structure 100 may be further provided with a side buffer member 200 in advance to prevent foreign substances or moisture from penetrating the edge portion in contact with the side wall. The side buffer member 200 is filled with first foreign matter or water to prevent mold and the like from occurring, and secondly, the air of the first air layer 104 and the second air layer 134 is not leaked at random. It functions to help perform a cushion function, the third function to prevent heat leakage into the wall, and to block the noise transmitted to the wall through the side wall through the fourth side wall. Therefore, it is provided in the lower part of the wall by the bonding method or the like.

When the bottom smoothness of the floor slab is not complete, the horizontal pulp material 103 performs a function of strengthening the floor smoothness with a horizontal pulp material or the like.

The elastic support 110 is to support the completely dry structure 100 from the top of the floor slab 102, and evenly distributes the load of the completely dry structure 100 to the floor slab (102). However, when the complete dry structure 100 is slumped while walking, pedestrians may feel uncomfortable or uneasy, and should be installed at appropriate intervals.

In the embodiment of the present invention, as shown in Figures 3 and 4, the elastic support 110 is arranged on the upper surface of the bottom slab 102 or horizontal pulp material 103 while maintaining a constant interval in the longitudinal direction. . The width of the elastic support 110 is suitably 90mm to 110mm specifically about 100mm to prevent settlement, and the distance between the elastic support 110 is also suitable about 100mm to form an air layer. .

The elastic support 110 is used a synthetic rubber, polyester (polyester) or expanded polyolefin (Expanded Poly Olefine) having an elastic force, if the shrinkage force is too high, because the support force can be reduced by long-term use, polyester as the main raw material , EPO or EPDM (Ethylene Propylene Diene Monomer) is used, but it is preferable to use other mixtures.

In addition, SBR, CR, EPDM, NBR, etc. can be used as synthetic rubber, and natural rubber (NR), ethylene vinyl acetate copolymer (EVA), polyethylene (PE), polypropylene (PP), polystyrene (PS), PVC foam or the like may be used.

As shown in FIG. 2, a first air layer 104 having a thickness of 15 mm is formed between the bottom slab 102 and the inorganic board 120 by the elastic support 110. Finally, the impact sound transmitted from the upper part of the completely dry structure 100 is weakened so as not to be transmitted to the floor slab 102, and at the same time, it performs a thermal insulation function.

The air layer 104 serves to block the transfer to the lower layer by absorbing and canceling the shock or noise generated in the upper layer by forming an air film, and additionally prevents heat loss.

The first inorganic substrate 120 and the second inorganic substrate 160 are intended to enhance walking comfort by enhancing durability.

The first inorganic substrate 120 is made of 9 mm thick with inorganic ingredients such as magnesium and silicon as the main raw materials, and has excellent strength and hardness to reinforce the strength of the completely dry structure 100 and at the same time completely dry and flame retardant. It is then effective in preventing fire. In the embodiment of the present invention, a magnesium inorganic board is mainly used. Although the magnesium inorganic board is effective in non-combustible and flame retardant, various minerals such as ocher may be further included to further reinforce it and increase functionality such as insect repellency.

The second inorganic board 160 is an inorganic board containing cement, and if bubbles or air layers are formed inside the inorganic board, the second inorganic board 160 is more preferable for noise reduction and shock mitigation. The second inorganic substrate 160 is a non-combustible board, which does not generate toxic gas even when the non-combustible board is burned in a fire.

The completely dry structure 100 of the present invention is characterized in that it is designed to be assembled in a mat shape, and as described above for the construction and durability, the length of the horizontal and vertical, respectively, within the range not exceeding 400mm x 600mm or It is preferable to form a square shape, and thus the inorganic board 120 is manufactured to a 1200mm x 900mm standard.

The dry panel lower portion 130 and the sound insulation pad 150 are intended to mitigate the impact delivered to the inorganic board 120, and are molded of a soft foamed synthetic resin product to absorb the impact and reduce noise. Among them, it is preferred to be made of expanded poly olefin (Expanded Poly Olefine), expanded poly propylene (Expanded Poly Propylene (EPP)), expanded polystyrene (EP Expanded Poly Styrene: EPS) or a mixture thereof. There may be a slight difference in the thickness or shape of the dry panel lower 130 and the sound insulating pad 150, the dry panel lower 130 may be inserted into the bottom surface of the dry panel 140 to be described later, sound insulation Pad 150 is preferably made of a thinner thickness.

As described above, the soft dry panel lower portion 130 and the sound insulation pad 150 perform a soundproof function that blocks shock sound by a predetermined elastic force and a vibration suppression function that suppresses vibration at the same time. In particular, the dry panel lower portion 130 and the sound insulation pad 150 are effective in blocking the light impact sound, such as the shoes of the upper floor.

As shown in FIGS. 5 and 6, the dry panel 140 facilitates the construction of the pipe (142 of FIG. 2) and prevents the heat transmitted from the pipe 142 from being lost to the bottom. The dry panel 140 is configured to form a second air layer 134 as shown in FIG. 2, and as shown in FIG. 7, a plurality of cylindrical support parts 144 are formed up and down, and the cylindrical At least one through hole 149 is formed at an end of the supporting part 144, and a seating part 146 on which the pipe 142 is seated extends back, front, left, and right between the supporting parts, and the seating part ( Another through hole 149 is protruded from 146, and a plurality of diaphragms 148 are formed across the edge and the center. In particular, the edge of the diaphragm is provided with concave-convex portions in which convex portions and concave portions are repeated, so that a plurality of dry panels 140 can be assembled. Here, the through hole 149 provided in the seating portion 146 is not protruded, but may be formed directly on the seating portion.

In addition, the diaphragm 148 functions to allow the dry panel 140 to be seated on the dry panel lower portion 130 or the first inorganic substrate 120, thereby increasing a pedestrian's walking feeling. In addition, the through hole 149 may be installed at any one side of the dry panel 140 as well as the end portion and the seating portion 146 of the cylindrical support 144, and acts as a passage for air. The sound insulation performance of the completely dry structure can be improved.

As described above, a second air layer 134 having a thickness of 30 mm is formed inside the cylinder of the support part 144 to cushion the impact sound transmitted from the second inorganic substrate 160. That is, the second air layer 134 serves to prevent a so-called 'sound bridge' phenomenon in which the impact sound transmitted from the second inorganic board 160 is transmitted to the first inorganic board 120. .

On the other hand, the upper surface of the dry panel lower 130, a plurality of holes (not shown) is inserted into the end of the base portion 144 is molded, as shown in the figure, the dry panel lower to enable insertion into the dry panel The top half of the edges are inward of the dry panel thickness, and holes can only be formed in the upper layer.

The finishing layer 170 is used, such as vinyl or paper board, wood, natural stone, tiles.

As described above, in order to prevent noise between floors caused by impacts by absorbing or cushioning shocks generated between floors in apartments and villas, a plurality of elastic supports are primarily provided on floor slabs or horizontal pulp materials. The first magnesium substrate is stacked in a stacked arrangement to form a first air layer, and the second substrate is formed using a dry panel having an uneven shape in which upper and lower surfaces are alternately opened on the first inorganic board. It can be seen that the technical idea is to form a double layer and to form a double air layer between the bottoms by forming an air layer and stacking the second inorganic board again on the dry panel. Within the scope of the basic technical idea of the present invention, many other modifications will be possible to those skilled in the art.

As described above, according to the configuration of the present invention, the following effects can be expected.

First, it is installed prefabricated, easy to construct even in a high-rise building, the effect is expected to be remodeled after construction.

Second, finish materials can be exchanged selectively, reconstruction is free when failing the quality test, and it is expected to have the effect of satisfying consumer's needs by blocking light impact sound as well as heavy impact sound.

Third, the air is shortened because no curing period is required after pouring because it uses fully dry prefabricated inorganic boards, and construction is possible regardless of summer and winter.

Fourth, an elastic layer is provided at the lowermost part at predetermined intervals, and sound insulation pads and the like are stacked between them, and dry panels are provided to prevent lifting.

Fifth, heat loss is low due to high heat storage and heat insulation performance, and noise absorption rate is high for interlayer noise.

Sixth, at least one support portion is formed at one side of the edge of the dry panel and at the center portion thereof, so that even when a pedestrian walks under a load, the walking feeling is increased, and noise generated by the expansion and contraction of the dry panel is prevented.
