The present invention relates to a buffer floor structure for buildings excellent in cushioning and sound insulation effect, and more particularly, the present invention includes a separate buffer member for excellent cushioning and sound insulation effect while reducing the height of the entire floor layer, The present invention relates to a shock absorbing floor structure for buildings having excellent cushioning and sound insulation effects so that a building floor including a shock absorbing member can be easily installed on a floor of a new building or an existing building.

As is well known, in urban areas, it is usually necessary to accommodate a large number of citizens in a small building area, so the construction of apartments, such as multi-family dwellings, is more active than a single house.

From the above reasons, many households must respect the privacy of each other and must solve the inter-floor noise problem in order to maintain community life. When the floor noise is generated from the upper floor, the lower-class residents become very anxious and cause the quarrel, and the higher-level residents are worried about their behavior, so the convenience of living among the vertical families is greatly reduced. Can be.

In particular, apartments with a long construction year have a wall structure (Slab: 135 to 180 mm), and thus, floor noise is higher, and recently constructed apartments have a ramen structure (Slab: 150 mm) or a wall structure (210 mm). ), The noise between floors is smaller. The smaller the area of the slab, the lower the resonance is, so the floor impact sound level is improved.

On the other hand, the conventional bottom layer structure is usually composed of a slab (Slab: 150㎜) constituting the floor and the wall, the upper surface of the slab is disposed a heat insulating layer for buffering and heat insulation, the light-weight foam concrete layer on the upper surface of the heat insulating layer (63) is arrange | positioned, the finishing mortar is arrange | positioned at the upper surface of the lightweight foam concrete layer 63, and the floor surface, the vinyl sheet, etc. are constructed on the upper surface of the finishing mortar.

Of course, such a ramen- and wall-structured building floor has a floor noise reduction effect than conventional wall-structured structures, but it is not yet satisfactory to reduce floor noise, and in recent years, building construction has been strengthened as a standard for building houses. Noise reduction is very important in the world.

Therefore, as a building material of the recent building floor, it is a trend to achieve high rigidity and light weight. Through this, it can be seen that the floor noise cannot be solved entirely by simply raising the height of the slab. If the height of the slab alone is used to solve the floor noise, the height of the floor must be very high. There is a problem that the construction cost must be passed on to the tenant, and the construction period also takes a long time.

In particular, in relation to the inter-floor noise in the underfloor structure formed on the slab structure, Article 14 (perimeter boundary walls, etc.) of the regulations on housing construction, etc. states, “The floor of the apartment house shall be one of the following subparagraphs: . 1. The floor impact sound between floors should be less than 58 decibels for light impact sounds (comparatively light and hard impact floor impact sounds) and less than 50 decibels for heavy impact sounds (bottom impact sounds caused by heavy and soft impacts). In this case, the floor impact sound shall be measured and determined by the Minister of Construction and Transportation, and the performance shall be verified by an organization designated by the Minister of Construction and Transportation regarding the structure. 2. A standard floor structure determined and announced by the Minister of Construction and Transportation. ”The standard floor structures described above are shown in FIGS. 1 to 5.

1 to 5 show different standard floor structures.

Referring to Figure 1, the standard floor structure 1 is a concrete slab (210 mm or more) 11, a heat insulating material (20 mm or more) (12), lightly foamed concrete (sequentially) upwards from the slab corresponding to the frame structure of the building 40 mm or more) 13, the finishing motor (40 mm or more) 14, and the bottom finish material 15 are laminated | stacked in order.

Referring to Figure 2, the standard floor structure 2 is a concrete slab (210mm or more) 21, the cushioning material (20mm or more) 22, light weight bubbles sequentially from the slab corresponding to the frame structure of the building upwards Concrete (40 mm or more) 23, finishing mortar (40 mm or more) 24 and the floor finishing material 25 are laminated in this order, the side buffer 26 is the wall and the sequence of the frame structure of the building It is configured to be interposed between the laminated floorings.

Referring to Figure 3, the standard floor structure 3 is a concrete slab (210 mm or more) 31, lightweight foam concrete (40 mm or more) 32, the heat insulating material (sequentially upward) from the slab corresponding to the frame structure of the building 20 mm or more) 33, the finishing motor (40 mm or more) 34, and the bottom finish material 35 are laminated | stacked in order.

Referring to Figure 4, the standard floor structure 4 is a concrete slab (210 mm or more) 41, lightweight foam concrete (40 mm or more) 42, the cushioning material (sequentially) upwards from the slab corresponding to the frame structure of the building 20 mm or more) 43, a finishing motor (40 mm or more) 44, and a floor finishing material 45 are laminated in this order, and the side buffer 46 is laminated in the order with the wall of the frame structure of the building. It is configured to be interposed between the floors.

Finally, referring to Figure 5, the standard floor structure 5 is a concrete slab (210 mm or more) 51, the cushioning material (40 mm or more) 52, the finishing motor in order upwards from the slab corresponding to the frame structure of the building (50 mm or more) 53 and the floor finishing material 54 are laminated in order, and the side buffer 55 is interposed between the wall of the frame structure of the building and the flooring laminated in this order.

As described above, all of the conventional standard floor structures commonly include a cushioning material or a heat insulating material, and optionally include lightweight foam concrete, by adjusting the thickness of the cushioning material, heat insulating material or finishing mortar according to the structure. The buffer effect and the sound insulation effect are obtained. However, in the conventional standard floor structure, since the structure of the layers to be laminated is not all modular except the floor finishing material, it is laminated by the method such as pre-cutting or pouring directly to the size of the floor where the floor structure is directly installed in the field. Since the floor structure must be completed, a lot of time is required for work, and nevertheless, there are problems such as deterioration of uniformity of quality or performance depending on the skill of the operator. In addition, even if a shock absorber is used, the thickness of the shock absorber must be thicker than a predetermined thickness in order to obtain a sufficient shock absorbing effect, such that the height of the floor is increased in the indoor space. In addition, the use of low-density styrofoam and ethylene vinyl acetate resin (EVA) in the ondol component layer prevents the sound of thumping noises generated during walking, which is transmitted to the lower generation, creating anxiety for the lower generation. However, there is a disadvantage in that it makes the indoor life uncomfortable even in the upper generation.

In addition, the above-mentioned standard floor structures basically contribute to the cost increase (KRW 60,000 / pyeong) because concrete slabs should be formed to be thicker than 210 mm, and are caused by depletion of raw materials that make up concrete slabs such as sand and gravel. There is a disadvantage that adversely affects the environment, such as the generation of radon gas due to environmental destruction and increased concrete usage.

An object of the present invention includes a separate shock absorbing member to reduce the height of the entire floor layer and to provide excellent cushioning and sound insulation effect, and to easily install a building floor including the shock absorbing member for the floor of a new or existing building.

It is interposed between the support and includes a spring for absorbing the impact.

As the anti-vibration structure, a pair of magnets including an upper plate and a lower plate may be used, instead of the spring, such as an elastic plate such as a rubber plate, an elastic body such as a sponge, or magnetic poles facing each other.

The dustproof structure also has a hollow cylindrical dustproof body into which a buffer means such as a spring is inserted therein, a lower support which is variably fixed to the inside of the dustproof body, and is detachably fixed to the upper end of the dustproof body. The upper cap may be made of a flange formed integrally with the outer peripheral surface of the dustproof body.

The lightweight foamed concrete layer directly casts the slurry of lightweight foamed concrete to form a continuous surface, or speaks the lightweight foamed concrete unit formed into a plate body having a predetermined size and a predetermined thickness in advance, and between these lightweight foamed concrete units Can be formed by adhering with a viscoelastic adhesive.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Fig. 6 and 7, the buffer floor structure for buildings excellent in the cushioning and sound insulation effect according to the present invention, by the concrete slab 67 and the concrete wall 68 constituting the building of a conventional multi-layer structure Insulation buffer 61 to be stacked on the concrete slab 67 of the interior space to be formed, the lightweight foamed concrete layer 63 stacked on the insulation buffer 61 and the light-foamed concrete layer 63 It comprises a cement mortar layer (64) and a flooring material (65) laminated on the cement mortar layer (64) to be laminated on; A plurality of cavities defined here by partition walls extending perpendicular to the ground, a dustproof structure 614 inserted into and fixed into cavities of some of the cavities, and the cavities. Among them, the dustproof structure 614 includes a heat insulating material filled with cavities other than the inserted and fixed cavities, and the dustproof structure 614 protrudes below the heat insulating buffer layer 612. The lower viscoelastic adhesive layer 611 is attached to the bottom surfaces of the thermal insulation buffer layer 612 and is positioned to be parallel to the thermal insulation buffer layer 612, and the upper viscoelastic adhesive layer 613 is laminated on the upper surface of the thermal insulation buffer layer 612. Characterized in that made.

That is, according to the present invention, the thermal insulation provided and devised in the present invention on the concrete slab 67 of the indoor space formed by the concrete slab 67 and the concrete wall 68 constituting a conventional multi-storey building The shock absorbing material 61 is laminated first, and by the structure and features of the heat insulating shock absorber 61, it is characterized in that it serves to prevent insulation and buffering and noise generation, thereby suppressing the generation of interlayer noise.

Lightweight foamed concrete layer (63) laminated on the thermal insulation buffer 61, cement mortar layer (64) and the flooring material laminated on the cement mortar layer (64) laminated on the lightweight foamed concrete layer (63) 65 may be understood to be the same as or similar to those used in the conventional standard floor structure (FIGS. 1 to 5). The hot water pipe 66 may be installed between the cement mortar layer 64 and the lightweight foam concrete layer 63 in the same or similar manner as the conventional art. In particular, the lamination or installation of the flooring 65 may also be used without any known aqueous adhesives or oil-based adhesives, as well as bonding the standardized flooring 65 using a known hot melt adhesive (hot melt adhesive), It can be understood that it can be fixed.

The thermal shock absorber 61 provided by the present invention, as shown in FIG. 7, includes a plurality of cavities defined by partition walls extending perpendicular to the ground, and cavities of some of the cavities. A heat insulation buffer layer 612 formed of a dustproof structure 614 inserted into and fixed to the inside, and insulating materials filled in cavities other than the cavity in which the dustproof structure 614 is inserted and fixed, and the heat insulation The lower viscoelastic adhesive layer 611 is attached to the bottom surfaces of the dustproof structure 614 protruding downward of the buffer layer 612, the lower viscoelastic adhesive layer 611 formed to be parallel to the thermal insulation buffer layer 612, and the upper side of the thermal insulation buffer layer 612. It characterized in that it comprises a top viscoelastic adhesive layer 613 laminated on the surface. The dustproof structure 614 has a structure similar to a heat insulating plate of a conventional honeycomb structure, and as shown in FIG. 8, the heat insulating plate 81 of the honeycomb structure is one top plate 811 and the top plate 811. A bottom plate 812 and a partition wall 813 interposed between the top plate 811 and the bottom plate 812, wherein the partition wall 813 is between the top plate 811 and the bottom plate 812. It extends in a vertical direction with respect to the upper plate 811 and the lower plate 812, which means that a plurality of cavities 814 are formed. Such a honeycomb heat insulating plate 81 can be understood to be well known to those skilled in the art can be purchased and used commercially. Insulation buffer 61 in the present invention is not using such a heat insulating plate, it was described as a reference in the structural aspect similar. That is, similar to the formation of a plurality of cavities, in the present invention, the insulating shock absorbing layer 612 itself by inserting and fixing the dustproof structure 614 having a structure as described below in some of the above-described cavity The dustproof structure 614 is characterized in that the cushion capable of absorbing the shock, thereby absorbing the impact applied from above to prevent the occurrence of noise and at the same time the dust among the cavities The remaining empty spaces in which the structure 614 is not inserted are filled with heat insulators to enable heat insulation. As the heat insulating material, ordinary heat insulating materials may be used without limitation, and preferably, styrofoam or urethane resin may be filled, but the present invention is not limited thereto. The size of the cavity may be in the range of 30 to 70 mm in diameter, preferably 50 mm. When the size of the cavity is formed to be less than 30mm, there is a problem that the vibration-proof structure 614 to be described later is small enough to not be inserted into the insert to be difficult to realize the buffer structure, if it exceeds 70mm, There may be a problem that the size of the individual cavities is too large to degrade the mechanical properties, in particular impact resistance. However, the present invention is not limited to the size of the diameters of these cavities, and if the cavities are too small for the dustproof structure 614 to be inserted therein, six cavities contiguous to the periphery thereof based on one cavity The dustproof structure 614 may be inserted and fixed into the large cavity to be merged with each other so as to be one large cavity.

In particular, as shown in FIG. 9, in the cavity 914 formed by the partitions 813 of the heat insulation buffer layer, lightweight foam concrete may be poured to increase the heat insulation effect, in this case, FIG. 9. When the lightweight foamed concrete 817 is filled into the cavity 814 as in (A), the central vent 816 formed on the bottom surface of the cavity 814 by the weight of the shock absorbing plate is located below. The light foamed concrete is prevented from leaking by being in contact with the upper end of the projection, and as the weight of the light foamed concrete in the cavity 814 decreases due to evaporation of curing and moisture over time, FIG. 9. As shown in (B), the lightweight foam concrete, which is already cured by curing even if the central vent 816 is spaced apart from the upper end of the protrusion of the buffer plate and is opened, It does not flow and, the water will continue to be able to escape from the concrete through the curing process through peripheral vents 815 in which the central ventilation hole (816), and the communication path to be discharged to the outside. In addition, the central vent 816 and the peripheral vents 815 communicated with each other function as an air trap, and thus, through the vents in response to the rapid escape of air when an impact is applied from the outside. Since it is forced to escape into a narrow gap, it can provide a shock absorbing effect and a noise generating effect by itself. A bottom embossing 818 may be formed on a bottom surface of the lower plate 812 on which the partition walls 813 are formed so as to reinforce the adhesive force with the adhesive layer thereunder.

The lower viscoelastic adhesive layer 611 is attached to the bottom surfaces of the dustproof structures 614 protruding from the thermal insulation buffer layer 612 below the thermal insulation buffer layer 612 and is formed to be parallel to the thermal insulation buffer layer 612. The lower viscoelastic adhesive layer 611 is formed of an adhesive synthetic resin layer and is in contact with the concrete slab 67 which functions as a floor of an existing or newly constructed building at the same time as the buffering and insulating layer 612 itself. It functions to be fixed and at the same time to insulate and cushion. The material or adhesive component of the rubber constituting the lower viscoelastic adhesive layer 611 can be used without limitation, and it will be understood by those skilled in the art that any elastic rubber material having commercially available adhesiveness can be used.

Like the lower viscoelastic adhesive layer 611, the upper viscoelastic adhesive layer 613 is formed to be insulated and buffered at the same time as fixing the layer to be fixed on the insulating buffer layer 612, and thus the lower viscoelastic adhesive layer 611. The same or similar materials may be used.

Complementary layers 615 may be further stacked on the upper viscoelastic adhesive layer 613. The complementary layer 615 may be fixed by attaching a plastic mesh or nonwoven fabric to the upper viscoelastic adhesive layer 613. These complementary layers 615 and the concrete constituting the lightweight foamed concrete layer 63 in the case where the lightweight foamed concrete in a slurry state is directly cast on the insulation buffer layer 612 to form the lightweight foamed concrete layer 63. It is preferable to use the complementary layer 615 because it functions to enhance the adhesion of the. The lightweight foamed concrete layer 63 may be formed by directly pouring lightweight foamed concrete in a slurry state as described above, or may be formed by speeching the lightweight foamed concrete unit 631 as shown in FIG. 14. In this case, to the upper viscoelastic adhesive layer 613 of the heat insulating complete layer layer to attach the light-bubble foam concrete unit 631 directly on the upper viscoelastic adhesive layer 613 without laminating the complement layer 615 as described above. As a result, the lightweight foamed concrete layer 63 can be formed. In this case, a viscoelastic adhesive 632 may be interposed between the lightweight foam concrete units 631, and the viscoelastic adhesive 632 is made of the same or similar material as that of the lower viscoelastic adhesive layer 611. Can be.

As shown in FIGS. 10 and 11, the dustproof structure 614 of the thermal insulation buffer 61 has a hollow cylindrical upper portion to form a space in which a shock absorbing means such as a spring 614-5 is provided. The upper case 614-1 is formed in a closed shape and the lower part is opened, the upper protrusion 614-2 formed at the lower end of the upper case 614-1, and extends into the upper case 614-1. Formed on the upper end of the lower support 614-3 and the lower support 614-3 and engaged with the upper protrusion 614-2 of the upper case 614-1 to insert the lower support 614-3. ) Is interposed between the lower protrusion 614-4 for variably fixing the upper case 614-1 and the upper case 614-1 and the lower support 614-3 to absorb shocks. 614-5. Therefore, by fixing the insulation buffer 61 to the upper surface of the upper case 614-1, the insulation buffer 61 is elastically supported by the anti-vibration structure 614 to prevent the buffer and noise generation effect Can be represented. The dustproof structure 614 is inserted into and fixed in the cavity formed in the insulation buffer 61.

The anti-vibration structure 614 is an upper plate (614-6) and a lower magnet (614-7) are arranged so that the magnetic poles such as elastic plates, such as a rubber plate, an elastic body, such as a sponge or the like opposite to each other instead of the spring (614-5). A pair of magnets may be used. Instead of the elastic force of the spring 614-5, the elastic force of an elastic body such as a sponge or the repulsive force of a pair of magnets may act the same as the elastic force of the spring 614-5.

When the pair of magnets are used, the magnets must be completely fixed in place in order to obtain repulsive force against each other. In this case, as shown in FIG. 12, at the inner bottom surface of the upper case 614-1. It may be fixed by the magnet fixing means (614-8) such as protrusions projecting downward, otherwise it may be fixed to the inner bottom of the upper case (614-1) with an adhesive or the like.

In addition, as shown in Figure 13, instead of the dustproof structure 614, fastening dustproof structure 617 may be used, which is a hollow cylindrical dustproof in which a buffer means such as a spring (not shown) is inserted therein. The main body 617-1, a lower support 617-2 that is variably fixed to the inside of the dustproof body 617-1, and are detachably fixed to the upper end of the dustproof body 617-1. The upper cap 617-3 and the flange 617-4 integrally formed on the outer circumferential surface of the dustproof body 617-1. The fastening type dustproof structure 617 may be fixed between the flange 617-4 and the bottom surface of the upper cap 617-3 by interposing the insulation buffer layer 612 to fix the insulation buffer layer 612. The fastening dustproof structure 617 is fixed to the heat insulation buffer layer 612, which is a separate heat insulation layer separated from the case of further stacking the heat insulation buffer layer 612 in a multi-layer structure or a separate heat insulation layer (styrofoam). Can be fixed together.

A wall sound insulating material 62 may be further mounted between the buffer floor structure and the concrete wall 68, wherein the wall sound insulating material 62 is perpendicular to the ground as shown in FIGS. 15 and 16. Including a sound insulation side plate 621 extending in the direction, a sound insulation bottom plate 622 bent in a vertical direction with respect to the sound insulation side plate 621, and a hot water pipe groove 623 formed on the surface of the sound insulation bottom plate 622 Characterized in that made. The sound insulation side plate 621 is interposed between the shock absorbing floor structure and the concrete wall 68 to block vibration or noise generated when an external force is applied to the shock absorbing floor structure from being transmitted to the concrete wall 68. Do it. In addition, the sound insulation bottom plate 622 also functions to block the corner portion of the building that does not extend between the buffer floor structure and the buffer structure, the same or similar to the sound insulation side plate 621. The hot water pipe groove 623 formed on the surface of the sound insulation bottom plate 622 serves to align the hot water pipes, which are installed for the flow of hot water, in particular for heating, and to facilitate the operation of the hot water pipe. Do it.

The sound insulation side plate 621 is formed with a first indicator groove 627 indicating the height of forming the lightweight foam concrete layer and second indicator grooves 628 indicating the height of forming the finishing mortar layer formed thereon. It can be made to facilitate the lamination work to form the lightweight foam concrete layer and the finishing mortar layer.

The ALC of the ALC lightweight foam concrete unit 631 is an abbreviation of autoclaved light-weight concrete, and instead of pouring concrete and curing it to form concrete, it mass-produces standardized concrete in a factory to assemble in the field. The term “ALC” used here is a term made in Japan when it was introduced to Japan from Europe in the late 1950s and is currently used only in Southeast Asia such as Japan, Korea, Malaysia, Indonesia, Taiwan, and Thailand. In other countries, the term “AAC” is commonly used, and in some European countries, it is called “Cellular concrete.” ALC was developed by Hoffmann in Germany in 1889 and Ericsson in Sweden in 1923. Commercialization was made and supplied by Ytong, Sweden in 1929. It was developed and used to meet the needs of building materials with low thermal insulation and constructional climate constraints in northern European countries with cold climate conditions. After World War II, it was restored to Joseph Hebel of Germany from 1945. It was developed and used in earnest by the company, and is currently being produced and supplied in Korea.
