Description

Floor mat for preventing floor noise in buildings with a return function and a flow blocking function{FLOOR MAT FOR PREVENTING NOISE BETWEEN FLOORS OF BUILDING WITH RETURN FUNCTION AND FLOW BLOCKING FUNCTION}

The present invention relates to a floor mat for preventing floor noise in a building, and more particularly, to a floor mat for preventing floor noise by dispersing the load applied to the floor.

In general, the floor impact sound is a sound transmitted to the lower floor through a floor slab, ceiling or wall when an impact is caused by human walking or falling objects on the upper floor of an apartment or villa.

The floor impact sound is a light weight impact sound that generates a lot of high-frequency components such as the falling sound of objects such as bowls or balls, a movement sound of a chair, and a heavy impact sound that generates a lot of low-frequency components such as adult walking or jumping of children. Are distinguished.

The concrete slab that separates the lower floor from the upper floor is a good sound insulation material because it blocks air propagation sound well, but when a shock or vibration is directly applied to the concrete structure, it is converted into a solid sound wave and hardly canceled out and transmitted to other adjacent generations. It has the characteristics of being emitted.

Therefore, in this way, in the case of building more than two stories in the west where the bed is used, such as Europe or the United States, a method for minimizing the impact sound between the upper and lower floors has been devised. It is a situation that pays special attention to avoid this.

As a conventional technique for overcoming the above problems, Korean Patent Registration No. 10-666049 discloses "Soundproof and Dustproof Floor Structure of Buildings Using Damping Layers". However, the soundproofing and dustproof floor structure of buildings using conventional damping layers have insufficient bonding force between the damping layer and the upper slab or lower slab, and the damping layer is separated from each other and separated, thereby preventing noise and vibration generated from the floor of the building. It was difficult to extinguish.

The technical problem to be achieved by the present invention is to provide a floor mat for preventing floor noise of a building having a function of blocking and returning a flow path between storage members to reduce floor noise by dispersing the impact by dividing the floor surface into cells. .

The technical problem to be achieved by the present invention is not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary knowledge in the technical field to which the present invention belongs from the following description. There will be.

At this time, the storage member 21, the lower surface may be supported from the bottom, the upper plate 10 may be located on the upper surface. The storage member 21 may be formed of a double space paper, and the thickness may be changed by a user setting.

In addition, any one of the storage members 21 located at the edge of the plurality of storage members 21 may be formed with a gas inlet 212 having a flow path formed therein to inject gas into the gas receiving space 211, The gas inlet 212 may be formed with a valve (not shown) that opens and closes the flow path.

The moving member 22 is formed between each pair of storage members 21 to communicate with the gas receiving space 211. In this case, the moving member 22 may be formed with a flow path 223 in the longitudinal direction therein, and the flow path 223 may communicate with the gas receiving space 211 of the storage member 21.

Referring to FIG. 5, the moving member 22 may include a first surface 221, a second surface 222, and a flow path blocking surface 224.

Both sides of the first surface 221 and the second surface 222 may be coupled to the storage member 21 different from each other, and the flow path 223 may be formed by mutual coupling. At this time, the second surface 222 may be positioned on the first surface 221, and may be formed integrally with the first surface 221.

The flow path blocking surface 224 may be disposed parallel to the flow path 223 between the first surface 221 and the second surface 222, and an area of one surface may be coupled to the second surface 222. .

At this time, the rest of the area that is not coupled to the second surface 222 may be arranged to face the inflow direction of the gas, and is in contact with or spaced apart from the first surface according to the degree of gas injection into the gas receiving space 211, the flow path 223 can be opened or closed. For example, when a sufficient amount of gas is filled in the gas receiving space 211 of the storage member 21 located in the direction in which the gas flows, the air pushes the flow path blocking surface 224 with a strong pressure toward the first surface side. You can cut off the flow path.

The flow path blocking surface 224 may be combined with the second surface 222 by thermal bonding, and in this case, the flow path blocking surface 224 is a heat resistant coating layer 225 having a property that is not adhered by heat to the other surface of a region ) May be formed. That is, when the second surface 222 and the flow path blocking surface 224 are heat-sealed to each other, the flow path blocking surface 224 and the first surface 221 are not thermally bonded to each other due to the heat-resistant coating layer 225. 223) is not blocked.

According to an embodiment of the present invention, the flow path blocking surface 224 may be formed with one or more sealing projections 2221 having a semi-circular cross-section on the other surface facing the first surface 221, the first surface ( 221, a sealing groove 2211 having a shape corresponding to the sealing protrusion 2221 may be formed on one surface facing the flow path blocking surface 224. That is, when the flow path blocking surface 224 comes into contact with the first surface 221, the sealing projection 2221 is fitted into the sealing groove 2211 and the space between the flow path blocking surface 224 and the first surface 221 This can be tightly sealed.

On the other hand, the first surface 221 and the second surface 222 may be formed of polypropylene (Polypropylene) material so as not to expand upon injection of the gas, the flow path blocking surface 224 is formed of Nylon (Nylon) material Can be.

Since the moving member 22 is formed in this way, the user can fill the gas in a plurality of storage members 21 through one gas injection port 212, and the storage member 21 in which a certain amount or more of gas is filled is The communication is blocked, so gas movement between the storage members 21 does not occur. That is, the storage member 21 can be supported by the load applied to the upper plate 10 without falling down, and even if any one storage member 21 is damaged and gas leaks, other storage is adjacent. It does not affect the member 21.

The support part 30 is formed between the pair of top plates 10 to interconnect the pair of top plates 10, and can support the top plate 10, and can reciprocate according to the applied load. Can be formed.

3 and 4, the support 30 may include a head member 31, a moving rod 32, a guide tube 33 and a pressing member 34.

The head member 31 is formed to be wider than the gap between the pair of top plates 10, and may be disposed between the top plates. The head member 31 may have a tapered groove recessed along the outer circumferential surface of the side surface, and may be spread over the top plate 10 by the tapered groove. That is, a part of the head member 31 may be disposed on the upper portion of the top plate 10 to be exposed to the outside, and the other part may be disposed between the pair of head members 31.

The moving rod 32 may be formed in a circular or polygonal shape, and may be formed to extend in the longitudinal direction under the head member 31.

At this time, a first screw acid may be formed on the inner circumferential surface of the pressing member 34, and a second screw acid meshing with the first screw acid may be formed on an upper portion of the outer circumferential surface of the moving rod 32. That is, the pressing member 34 moves to the head member 31 side along the thread, and can press the upper plate 10.

According to an embodiment of the present invention, the support portion 30 may further include a barrel-type coil spring (35, hereinafter, coil spring) coupled to the lower surface of the moving rod 32.

Referring to FIG. 6, the coil spring 35 is a compression spring that resists a force to be compressed by moving the moving rod 32 to a reference position when the upper plate 10 or the head member 31 is released from pressure. Can be formed. At this time, the reference position may be the position of the moving rod 32 when the pair of top plates 10 connected by the support 30 are parallel to each other.

The coil spring 35 may be formed in plural, and may be disposed at mutually symmetrical positions around the moving member 22 located inside the guide tube 33. In other words, the moving member 35 may be disposed in a space spaced between the coil springs 35.

According to an embodiment of the present invention, the moving rod 32 may be formed with a spring groove (not shown) having a diameter larger than the maximum diameter of the coil spring on the lower surface, the coil spring 35 has an upper end It can be combined with the top surface of the spring groove. In addition, the height of the spring groove may be equal to or higher than the height when the coil spring 35 is completely compressed.

Due to the formation of the spring groove, the coil spring 35 can be prevented from being detached from its original position in the process of being compressed, and the moving rod 32 can contact the lower surface of the guide tube 33.

7 is an exemplary view showing a state in which the moving rod 32 presses the moving member 22 among the floor mats 1 for preventing floor noise in a building according to an embodiment of the present invention.

The support portion 30 may be pressurized by the load applied by the top plate 10 or the head member 31, and accordingly, the moving rod 32 may move up and down along the guide groove 331. At this time, when the support portion 30 is pressed with a predetermined force or more, the moving rod 32 may be moved to come into contact with the lower surface of the guide groove 331 to block the flow path 223 of the moving member 22.

In more detail, the moving rod 32 moves downward by pressing and may press the second surface 222 located inside the guide tube 33 to block the flow path 223. At this time, one region of the second surface 222 that is pressed by the moving rod 32 is formed in a wrinkle shape, and when pressed by the moving rod 32, the wrinkle is flattened and one surface of the first surface 221 Can be in contact with.

As described above, the present invention primarily blocks the flow path 223 by the flow path blocking surface 224 and secondly blocks the flow path 223 by the moving rod 32 to move the gas between the storage members 21. This may not happen. That is, the storage member 21 can support it without sitting down even if a high load is applied.
