       The present invention relates to a floor anti-vibration member supporting a double floor and a construction method of the double floor using the same, which significantly increases the blocking rate of the floor impact sound transmitted between the upper and lower floors in multi-family multi-unit houses such as apartments and villas.

In the case of the general structure in which lightweight foam concrete is installed on the cushioning material in the floor shock sound blocking structure of the apartment house. Since shock-absorbing material is distributed over the entire surface of the floor slab, there is a big limit on the interception of noise by increasing the transmission surface of the impact energy, and delaying the construction period according to the curing period after pouring lightweight foam concrete. Is generated.

On the other hand, there is a double bottom structure to block the floor shock sound by separately forming a second floor layer on the floor slab and using a plurality of dust-proof rubber disposed between the two floor layers to complement the above problems.

However, since the anti-vibration rubber applied to the structure of the double bottom consists only of a rubber body having only a damping rate of the impact energy due to viscoelasticity, there is a large limit in blocking the floor impact sound, and the thickness of the anti-vibration rubber is increased up to 2 times to increase the anti-vibration properties. Increasingly, the effect is not great and the economics are significantly lower. In addition, as the thickness of the anti-vibration rubber increases, the height of the double-floor structure also increases, so it is difficult to apply to the remodeled apartment buildings that do not change the floor height of the apartment house or change the floor height in the building.

In addition, in the double bottom structure, in the case of the wall dustproof member which blocks the shock sound transmitted from the second bottom layer to the wall surface, the synthetic resin foam of a single material or two different synthetic resin foams may be composed in combination, but the synthetic resin foams are not opened. Since the outside of the air propagation sound transmitted from the second floor layer to the floor slab through the air layer is not externally generated, the amplification rate increases when the floor slab or the second floor layer is generated, which is one of the reasons for increasing the interlayer noise.

In addition, if the heating layer is a wet heating layer in which the mortar is poured and the panel supporting the heating layer is a wood board such as plywood or particle board, the barrier of moisture penetrating into the panel during mortar pouring is limited. Since the long-term durability of the trial was not guaranteed, it was difficult to apply economical wood board as a material for the panel supporting the heating layer.

In addition, the double bottom structure has a problem that can reduce the hygiene in the living space due to bacteria propagation by moisture in the sealed air layer formed between the floor slab and the second floor layer.

In addition, in the construction method of the double-bottom structure, as shown in Figure 21b, when the level adjustment work for maintaining the horizontal level of the support plate layer 80 forming the second floor layer is installed a plurality using a horizontal adjuster 150 made of one support bar Excessive construction time was generated by adjusting all the heat in the horizontal and vertical directions (X) (Y) of the floor dustproof member.

In addition, when heating the floor in the double-floor structure, while supporting the heating layer, it does not block the radiant heat, which is the electromagnetic wave radiated from the outer surface of the panel installed on the top of the floor dustproof member to the air layer and transmitted to the floor slab, and thus the heat caused by heating. The loss rate was high.

The present invention is to solve the above problems in the structure of the double bottom spaced apart from the floor slab to form a second floor layer, the impact energy transmitted from the second floor layer to the floor slab shock absorbing material and the buffer material and It is blocked as a multi-layer floor dustproof member that obtains a high attenuation rate by increasing the reflectance of impact energy due to the density difference between high density materials. External emission of impact energy delivered to the floor slab is possible, and numerous contact boundary points are formed on the transmission path of the impact energy, so that a wall dustproof member that increases the transmission loss rate is applied, or is completely spaced between the wall and the second floor layer. Providing a double bottom structure that greatly increases the blocking rate of light weight and heavy impact sound by forming a second bottom layer. The.

In addition, the double-floor structure provides a double-floor structure that completely blocks moisture from penetrating the lower part of the double heating system while removing moisture inside the air layer enclosed under the double-floor, and blocks radiant heat passing through the air layer during floor heating. To provide.

In addition, it is to provide a construction method of the double-floor structure to quickly complete the level adjustment work for a plurality of floor anti-vibration member during the level adjustment work for horizontal maintenance of the double floor.

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

       1 is an exploded perspective view and a coupled state of the floor-proof dustproof member for supporting a double bottom of the present invention, Figure 2a is a cross-sectional view of the floor dustproof member according to the configuration of FIG.

       The bottom dustproof member 1 installed on the bottom slab S1 and blocking the impact energy transmitted from the second bottom layer A to the bottom slab S1 is a buffer absorbing material that absorbs shock and is composed of one or more numbers. The shock absorbing plate 2, which is laminated between the shock absorbing plate 2 or the bottom of each of the shock absorbing plate 2, an impact blocking plate 3 made of a high-density material to increase the reflectance of the impact energy, and the shock absorbing plate 2 ) And fixing means (5) for maintaining the coupled state of the impact shield plate (3).

       The shock absorbing plate (2) attenuates the impact energy by absorbing vibration due to the impact, and is composed of a rubber having a hardness of about 35 to 50 degrees, which is good for absorbing energy due to elasticity and thermal energy of the impact energy due to viscosity. Most preferably, but it is also possible to apply a shock-absorbing material such as soft PVC, a synthetic resin foam, cork.

       In addition, the transmission loss at the contact interface between fibers formed innumerably as a large amount of fibers are stacked, but the volume ratio of the material in the total volume is about 10%, and the remaining 90% is a void state. It is possible to use organic and inorganic fibrous molded articles that are press-molded with PET or glass fibers, which together with the transmission loss of the impact energy is reduced.

       The fibrous molded body has a compressive resistance of about 0.5 to 5 kg / cm² at a density of 200 to 300 kg / m³, which is resistant to a load transferred from the second bottom layer A, and harmful dust during cutting compared to inorganic fibers such as glass fibers. It is an organic fiber molded body such as PET fiber which has no attenuation and has good damping rate and handleability of impact energy due to sound speed difference in the fiber structure, and its melting point is greatly shortened so that the molding cycle is greatly shortened during compression molding by thermal pressure. It is preferred to be configured and possible for a density of 120 to 400 kg / m³.

The shock absorbing plate 2 may be composed of two to three layers with a thickness of about 8 to 15 cm in consideration of the general height of the bottom dustproof member 1 according to the double bottom structure, and the transmission of impact energy to one side thereof. Hollows 7 and grooves 8 and 9 or projections 11 can be formed to reduce the consumption of cotton or material.

6A, the shock absorbing plate 2 may be made of a heterogeneous material 57 that is distinguished from the shock absorbing material with respect to any one or more of the shock absorbing plates 2 made of the shock absorbing material.

In addition, for one shock absorbing plate (2) made of a buffer material as shown in Figure 6b, while the buffer material 56 is basically composed of a heterogeneous material (57) that is separated from the buffer material 56 is a composite configuration This may be applied to any one or more of the entire shock absorbing plate (2).

Meanwhile, the shock absorbing plate 3 having a thickness of about 1 to 3 mm is made of a high density material having a large difference in density from the material forming the shock absorbing plate 2, so that the shock absorbing plate 2 and the shock blocking plate 3 are separated. By increasing the reflectance of the impact energy according to the density difference between the two media at the interface contacting each other, the attenuation rate of the heavy impact sound is greatly increased by lowering the amplitude value of each frequency band of the vibration wave.

The high-density material constituting the impact blocking plate 3 is most preferably made of lead having a specific gravity of 11.36 or a high-density heavy metal such as iron, copper, zinc, and stainless steel having a specific gravity of 7.0 or more, and other light metals such as aluminum may be applied. However, it is found that the application of heavy metals having a specific gravity of 4.0 to 5.0 or more is preferable for effective attenuation of the heavy impact sound. Here, the metal constituting the impact shielding plate 3 may be an alloy metal or a powder metal.

The shock absorbing plate 3 is disposed between or at the bottom of the shock absorbing plate 2 capable of secondaryly damping the shock energy primarily attenuated by the buffer material, but located at the top of the shock absorbing plate. At the top of (2), it may be arranged without much relation with the damping rate of the impact energy.

And when the shock shield plate (3) is coupled to the bottom of the shock absorbing plate (2) located at the bottom in the configuration of the bottom anti-vibration member (1) is coupled to a metal screw or synthetic resin screw as shown in Figure 8a and 8b By placing the projections 60, it is possible to reduce the contact cross-sectional area with the bottom slab (S1), the head of the screw can be coupled to the buffer cap 61 made of rubber or soft synthetic resin material.

In addition, unlike the composite structure of the shock absorbing plate (2) and the impact shielding plate (3), the bottom dustproof member (1), the fiber molded body 59 and the buffer material without the impact shielding plate (3) as shown in FIG. (58) can be configured in combination.

On the other hand, the fixing means (5) for maintaining the combined state of the shock absorbing plate 2 and the impact blocking plate (3) is a shock absorbing plate (2) and the impact blocking plate (2) on the side wall (4a) of the container having a container shape ( 3) When the shock absorbing plate (2) and the impact shielding plate (3) is inserted into the support housing (4) formed with a support projection (6) formed therein to reduce the cross-sectional area of contact and prevent the separation thereof, Minimizes the impact energy delivered to the side wall 4a of the support housing 4 while preventing side or bottom separation. The support housing 4 may be configured such that the support protrusion 6 supports the inner side of the hollow portion 7 of the shock absorbing plate 2 and the impact blocking plate 3 as shown in FIG. 2B.

3A shows another embodiment of the fixing means 5, in which the coupling thread 22 and the support protrusion 23 for reducing the transfer surface of the impact energy are formed on the side wall 21 of the support housing 20. The groove (9) avoids the interference with the projection (11) formed on the shock absorbing plate (2) located at the top of the plate (32) of the hot (30) formed with the thread (31) for coupling with the support housing (20) The through hole 33 is formed so that the plate surface 32 is inserted to a predetermined depth of the support housing while the plate surface 32 of the hot 30 is inserted into the groove 9 of the shock absorbing plate 2. 20 and the hot (30) is fastened by the coupling means (M) to completely block the separation of the shock absorbing plate (2) and the impact blocking plate (3).

Here, the step (C) between the upper surface of the cover 30 and the shock absorbing plate (2) located at the uppermost end is made of a height in consideration of the displacement amount due to the load, the support housing 20 and the cover 30 of As shown in FIGS. 3D and 3E, the first catching jaw 38 and the second catching jaw 39 are formed on the outer edge of the cover 30 at the upper end of the side wall 21 of the support housing 20. Or, the groove may be formed so that the upper edge of the side wall 21 of the support housing 20 is coupled to the outer edge of the warmer 30 by an interference fit.

3b shows the shock absorbing plate 2 and the shock shield plate 3 by inserting the cushioning material 34 in place of the support protrusion 23 of the support housing 20 in the configuration of the fixing means 5 according to FIG. 3a. The damping rate of the impact energy transmitted to the side wall 21 of the support housing 20 is further increased.

In addition, the fixing means 5 penetrates through the plate surface 32 to a predetermined depth of the outer circumferential surface of the impact absorbing plate 2 positioned at the top of the plate surface 32 of the cover 30 as shown in FIG. 3C. The ball 36 is formed, and the shock absorbing plate 2 positioned at the top thereof forms a locking jaw 37 so that the locking jaw 37 interferes with the plate surface 32 of the hot 30 to achieve the object. Can be.

In this case, as shown in FIG. 20, when the double-sided adhesive tape is attached, heat of impact energy due to high viscosity is provided between the tape layer N1 constituting the double-sided adhesive tape N, the impact shielding plate 3, and the shock absorbing plate 2. Since the pressure-sensitive adhesive layer N2 is formed, the blocking rate of the bottom impact sound can be further increased.

The pressure-sensitive adhesive layer (N2) is bonded to the outer surface of the tape layer (N1) in the state in which the adhesive (P2) is applied, the synthetic resin film (P1) of about 0.01 ~ 0.1mm thickness is bonded thereon and the outside of the synthetic resin film (P1) It is preferable that the adhesive P2 is applied to the surface again, and the adhesive P2 may be made of an acrylic or silicone type having low viscosity change over time as compared with the rubber type.

The bottom dustproof member 1 may be constructed in a state in which the shock absorbing plate 2 and the impact shielding plate 3 are laminated with the fixing means 5 excluded, and the fixing means in the bottom dustproof member 1.

Consisting to the upper surface of the bottom dustproof member 1, the upper support 51 may be inserted into the inner hollow portion 7 of the bottom dustproof member 1 when the height is adjusted, the support screw ( The lower support 53 separated by the 52a) and the support plate 52b may be configured as an integrated body as shown in FIG. 9B.

The level adjusting member 50 will be able to use a variety of configurations using the existing bolts, etc., of course, it is possible to apply a variety of means other than the method using a screw thread in height adjustment.

10A and 10B show an example of a coupling method between the level adjusting member 50 and the bottom dustproof member 1, wherein the protrusion 62 of the shock absorbing plate 2 located at the top thereof is the level adjusting member 50. It may be inserted by the interference fit inside, or the projection jaw (63) of the shock absorbing plate (2) can be caught on the locking jaw (64) of the level adjusting member (50), and separately from the level adjusting member (50) It is also possible to attach the double-sided adhesive and adhesive tape between the and the bottom dustproof member (1).
