The present invention is on the concrete slab to reduce the floor noise of the multi-storey building to reduce the floor impact sound, and to the on-floor floor structure to prevent the loss of heating heat, more specifically the floor to replace the conventional insulation buffer layer The present invention relates to a floor structure for more effectively absorbing impact sound and simplifying construction, and an anti-vibration insulating module plate used therefor.

In general, the floors and floors of apartments, multi-family houses, tenement houses, officetels or buildings are divided by concrete slabs. On these slabs, styrofoam is usually installed on the slab for insulation and heating piping, foamed concrete is poured on it, heating is plumbed, and finally flooring is carried out to the plastering mortar.

However, despite the slab floor construction, the multi-storey building delivers the impact sound and friction sound to the lower floor through the slab when impact or friction is applied to the floor due to human walking, falling of objects, or moving equipment. Therefore, there was a problem that the noise pollution due to the noise between floors is serious.

The noise between floors is generally divided into light impact sound containing high frequency noise such as falling impact sound of object and moving friction sound such as pinch, and heavy impact sound, which is mainly low noise caused by walking or adult running. In recent years, as the problem of inter-floor noise has been seriously raised, the standard floor which the light impact sound satisfies 58 decibels (dB) or less and the weight impact sound satisfies 50 decibels (dB) or less is determined or notified by the Minister of Construction and Transportation. The regulations on housing construction standards for noise between floors, etc., to be constructed by structure, have been greatly strengthened and revised.

Conventional techniques for reducing the interlayer noise can be divided into two types, first is a wet floating floor structure, second is a double floor structure.

The wet floating floor structure is a construction method in the present multi-layered building as shown in FIG. 1, and the insulation buffer 11 having a level of 20 to 30 mm is laid on the slab 10, which is a concrete frame, to reduce insulation and floor impact sound. It is installed on the front surface, and the foam concrete 14, the heating pipe 16, the finishing mortar 17 is sequentially constructed. Insulation buffer 11 of the floating floor structure is low cost, easy to construct and has the advantage of reducing the impact of lightweight impact sound, but generally excellent, but most effective in reducing the impact of heavy impact sound with 20 ~ 30 mm buffer material It turned out to be few.

Therefore, various techniques have been proposed to solve the problem of wet floating floor structure.

For example, Korean Utility Model Registration No. 20-331857 discloses a styrofoam layer having heat insulation, soundproofing, and moisture resistance and a porous upper and lower nonwoven layers adhered to each other by an adhesive on the upper and lower sides of the styrofoam layer, and the upper nonwoven layer and the upper surface thereof. An interlayer noise reduction means composed of a natural foamed rubber layer with embossing is proposed, and Korean Utility Model Registration No. 20-345879 discloses a bubble layer formed by mixing foamed resin and concrete at the bottom of a finishing mortar layer on a floor slab between building layers. And an interlayer noise absorbing structure having an interlayer noise reducing member interposed between the bubble layer and the bottom slab, wherein the interlayer noise member has air intersected with the first absorbent layer and the protrusion and the recess regularly formed of a hard synthetic resin foam from the top. Interlayer consisting of a second absorbent layer composed of a containing layer and a flexible synthetic resin foam sequentially laminated The absorbent structure has been proposed.

However, the structure in which the interlayer noise reduction member is applied only considers the material combination or the shape change of the cushioning material, and does not differ from the floor structure to which the existing buffer material is applied.

Accordingly, a double bottom structure as shown in FIG. 2 has been proposed as an alternative for more effectively reducing the weight impact sound. The double bottom structure basically allows the ondol layer (pipe + mortar layer) to be pointed on the slab 20, thereby minimizing the path of the impact (vibration) energy received from the mortar layer to the slab 20, 21) can add a larger concentrated load to the vibration-proof material 22 arranged at regular intervals to enable more efficient dustproof design of the structure having excellent floor impact sound reduction performance. However, this mid-floor structure requires a leveling device for leveling the support plate 25 for the smoothness of the heating pipe 26 and the structural stability of the finishing mortar layer 27. Various problems have occurred, and structural stability and long-term durability have not been verified, and thus, it is difficult to replace the wet floating floor structure. On the other hand, in the case of a high-rise site, to increase the mortar pumping and to facilitate the finishing treatment during the pouring process, the water-cement mixing ratio of the mortar is larger than the theoretical value. There was a problem in the finishing process, due to the lack of proper drainage at the beginning.

The present invention has been devised to solve the above problems, adopting a double-floor structure excellent in weight impact sound reduction performance as well as light impact sound, do not require leveling of the support point, can maintain the smoothness of the heating pipe in any slab conditions In addition, it is the purpose to provide a double-floor structure with easy initial care and excellent workability when the mortar pouring is good initial drainage.

According to the anti-vibration insulation module board for reducing noise between floors according to the present invention devised to achieve the above object, in the on-floor floor structure constructed on the concrete slab between the upper and lower floors of a multi-layered building, lattice ribs are formed on the upper surface thereof. A square bottom support plate protruding downward on the bottom surface and having protrusions inserted into the anti-vibration rubber at regular intervals; Anti-vibration rubber is inserted into the projections on the lower surface of the anti-vibration module plate; It characterized in that it comprises a heat insulating material is filled around the dust-proof rubber.

In addition, the thickness of the plate alone except for the height of the grid-like ribs and protrusions in the bottom support plate has a range of 1 to 10 mm, the dust-proof rubber and the heat insulating material have a range of 15 to 50 mm, respectively, the total effective height of the assembled state Characterized in that it is 30 ~ 70 mm.

The anti-vibration rubber is characterized in that the outer diameter of the lower portion is larger than the outer diameter of the upper portion, and a constant groove is formed on the upper and lower surfaces thereof.

In addition, four corner portions of the anti-vibration insulation module plate is further formed with a U-shaped groove in the cross-section, when the U-shaped groove is viewed from the upper surface direction, the upper side and the right side of the anti-vibration insulation module plate is opened in the viewing direction, The lower side and the left side of the anti-vibration insulation module plate is characterized in that it is formed to open in the opposite direction.

In addition, the U-shaped groove has fastening holes formed at regular intervals on the upper side and the right side of the dustproof insulation module plate when viewed from the upper surface direction, and is inserted into and fastened to the lower side and the left side of the dustproof insulation module plate. Characterized in that the fastening projection is formed.

Further, according to the wet double bottom structure applied to the anti-vibration insulating module plate according to the present invention, the anti-vibration insulating module plate is constructed on a concrete slab, and the foam concrete is poured and cured on the lattice rib of the upper surface of the anti-vibration insulating module plate. And it is characterized by finishing with mortar after heating piping.

The features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings. Prior to this, the terminology or words used in this specification and claims are technical idea of the present invention based on the principle that the inventor can properly define the concept of the term in order to best explain his or her design in the best way. It should be interpreted as meanings and concepts corresponding to

3 is a cross-sectional view schematically showing a wet double bottom structure to which a dustproof insulation module plate according to the present invention is applied, and FIGS. 4A and 4B are plan and cross-sectional views illustrating a dustproof insulation module plate according to the present invention. Figure 5b is a perspective view of the anti-vibration insulation module plate according to the present invention from the front and rear, Figure 6 is a cross-sectional view showing a state of the two anti-vibration insulation module plate according to the present invention.

4 and 5, the anti-vibration insulation module plate according to the present invention is constructed on a concrete slab between the upper and lower floors of a multi-layered building, and lattice ribs 71 are formed on an upper surface thereof, Projections 75 inserted into the anti-vibration rubber 65 are formed at regular intervals, and the anti-vibration rubber 65 is inserted into the protrusions 75 on the bottom surface of the bottom support plate 70. ), And the insulating material 60 is filled around the anti-vibration rubber (65).

In one embodiment, the bottom support plate 70 is formed on the upper portion of the synthetic resin flat plate having a size of about 500 mm × 700 mm, thickness 3 mm at least 10 mm in height at a suitable interval, and the bottom The protrusion 75 is formed at a predetermined interval of about 10 mm in height. Since the upper portion of the support plate on which the foam concrete is poured forms a lattice rib, it is possible to prevent cracking of the foam concrete and to secure structural stability of the bottom.

The synthetic resin plate serves as a support plate for forming a double-bottom structure by separating the foam concrete layer 80, which is poured on the top, into a slab 50 and a point support form with the dustproof rubber 65 and the air layer therebetween. The lattice ribs 71 serve to maintain the structural stability by preventing cracks by maximizing rigidity while reducing the weight of the plate and increasing adhesion with the upper foamed concrete layer 80.

It is preferable that the total effective height of the bottom support plate 70, the anti-vibration rubber 65, and the heat insulating material 60 constituting the anti-vibration insulation module plate is 30 to 70 mm. This effective height means the total height of the anti-vibration insulation module board excluding lattice ribs in the state of assembling the floor support plate, the insulation, and the anti-vibration rubber. If the total effective height is less than 30 mm, the performance of reducing the floor impact sound is not excellent, and if the height exceeds 70 mm, the thickness may be too thick, which may cause problems.

The lower portion of the synthetic resin plate 70 has an organic foam insulation material such as EPS (extended Polystyrene), EPP (extended Polypropylene), EPE (extended Polyethylene), EVA (extended vinyl acetate), organic or inorganic fibers, etc. By drilling the insulating material 60 made of the material into the projection 75 and assembling the projection 75 with the shape of inserting the anti-vibration rubber 65 mount having a height of 15 to 50 mm into the insulating material 60, it is dustproof. The height from the rubber 65 to the flat plate excluding the ribs 71 constitutes a heat insulating and dustproof module plate having a height of 30 to 70 mm.

Existing double-floor module boards are not structured with the anti-vibration rubber inserted into the insulation, so the height of the anti-vibration rubber is added to the insulation so that the total thickness of the floor becomes too thick. Although there is no choice but to finish the mortar, in the case of the present design, since the dust-proof rubber is inserted into the insulation material, the total thickness of the floor can be kept thin, and both 40 mm foam concrete and 40 mm finishing mortar can be applied. have.

Here, if the applicable range for the dimensions of the vibration-proof insulation module plate member considering the workability and economics is as follows. The thickness of the plate alone except for the height of the lattice ribs 71 and the protrusions 75 in the bottom support plate 70 is appropriate in the range of 1 to 10 mm in consideration of workability, waterproofness, economical efficiency, and the like. The height of 71) is about 5 ~ 10 mm for the purpose of reinforcing the rigidity of the plate and preventing cracks of foam concrete. In addition, the thickness of the heat insulating material 60 is required at least 15 mm or more in order to satisfy the inter-floor heat transfer rate criteria, and considering the maximum thickness of the ondol floor that can be allowed in the future, the maximum thickness of the heat insulating material is preferably 50 mm or less. The anti-vibration rubber 65 layered like a heat insulating material may also be limited to about 15 to 50 mm for the same reason.

In terms of the floor impact sound blocking effect, the insulation 60 and the air layer in the lower part of the module block the heating heat lost to the slab 50 from the ondol layer and reduce resonance sound, and the dustproof rubber 65 is slab (50) from the ondol layer. It is responsible for reducing the floor impact sound by reflecting or absorbing the vibration energy transmitted to).

In addition, the dustproof rubber 65, the outer diameter of the lower portion is larger than the outer diameter of the upper portion, it is preferable that a constant groove is formed on the upper and lower surfaces.

As shown in FIGS. 4B and 5B, the anti-vibration rubber 65 may stably support the bottom support plate 70 on the slab 50 by forming the outer diameter of the lower portion larger than the outer diameter of the upper portion. In addition, the shape of the groove formed in the anti-vibration rubber 65 may be in the form of a circular or columnar groove, and may be formed in a suitable shape in consideration of the size, elasticity, and ductility thereof. In addition, the grooves may be formed in a suitable shape on the upper surface as well as the lower surface of the anti-vibration rubber 65.

Further, four corner portions of the anti-vibration insulation module plate are further formed with a U-shaped groove 77 in cross section, and the u-shaped groove 77 is viewed from an upper surface thereof, and the upper side and the right side of the anti-vibration insulation module plate are formed. Spread in the viewing direction, the lower side and the left side of the anti-vibration insulation module plate is formed to open in the opposite direction. Further, the c-shaped groove 77 has fastening holes 78 formed at regular intervals on the upper side and the right side of the anti-vibration insulation module plate when viewed from the top surface direction, and the fastening on the lower side and the left side of the anti-vibration insulation module plate. A fastening protrusion 79 is inserted into the hole 78 and fastened.

The plate and the plate connecting portion of the bottom support plate 70 are fitted with the U-shaped grooves (female and male) on both sides of the module plate as shown in FIG. 6, and the other fastening protrusion 79 is inserted into one fastening hole 78. To hook the hook. In this way, the module boards can be tightly interlocked with each other so that they can be constructed to prevent cement from leaking when foaming concrete is placed on the upper part, as well as foam concrete because there is almost no displacement between the boards when the boards are integrally assembled and stepped on. I exert a function to prevent the crack of mortar.

In the wet double bottom structure to which the anti-vibration insulation module plate according to the present invention is applied, as shown in FIG. 3, the anti-vibration insulation module plate is constructed on a concrete slab, and the lattice ribs 71 are formed on the upper surface of the anti-vibration insulation module plate. Plastering and curing the foam concrete 80, and after finishing the heating pipe 95 is finished with mortar (90).

Foam concrete 80 of about 40 mm is placed on the upper part of the module plate. Since foam concrete 80 has self-horizontality, the smoothness of piping can be ensured, and the strength is weak, so piping work is easy after curing. In addition, it has a certain level of water absorption, so that the initial drainage during mortar casting is improved, and the finishing time is greatly reduced. As cement is the main component, it is not only excellent in adhesion to mortar, but also appropriately disperses local load of mortar layer. It also acts as a buffer layer to ensure structural stability of the entire floor. This advantage of aerated concrete is also an advantage of a wet floating structure to which aerated concrete is applied. Therefore, the present invention can install the anti-vibration insulation module board as if it is installing the floating floor cushion material, thereby quickly forming the double floor structure, and by applying foam concrete on it, it secures the construction and structural stability on the same level as the wet floating floor structure. It is a double bottom structure.

No leveling work is required, the smoothness of the heating pipe can be maintained in any slab condition, and the initial water drainage is good during mortar casting, which has the effect of easy finishing and excellent workability.

In addition, it is possible to lower the total effective height of the floor support plate, the heat insulating material, and the anti-vibration rubber except the lattice ribs to 30 to 70 mm.

In addition, the joints of the module plate can be engaged by the up-down fitting and the hook-filling method, thereby exhibiting a waterproof function when foam concrete or mortar is poured on the upper part, and there is no shear phenomenon at the boundary where the plate meets the plate. Cracks can be prevented.
