Description

Impact absorption device and application thereof in interlayer noise blocking structure
Technical Field
The present invention relates to an impact absorbing device and an interlayer noise blocking structure, and more particularly, to a device that can absorb an impact generated on a floor of a building and a structure that can block interlayer noise generated in the building thereby.
Background
In recent years, the form of buildings is becoming more concentrated in multi-story public houses such as apartments and villas. In the above-described public houses, interlayer noise is inevitably generated by floor impact sound, which leads to an important social problem such as contradiction between occupants. Therefore, in order to ensure a quiet living environment, efforts have been made to realize a performance capable of blocking floor impact sound.
The floor impact sound includes a moderate impact sound such as a sound of bouncing of a child and a light impact sound such as a sound of pulling a chair. The main cause of the contradiction between floors is severe impact sound, and the current proposal is to adopt a reinforcing structure body such as increasing the thickness of a concrete floor of a building floor. However, if the thickness of the concrete floor of the building is increased, not only the volume of the floor slab is increased but also the self weight of the building is increased, thereby further increasing the size of main structural components such as beams, pillars, and foundations. Therefore, it is inevitable to raise the structure of the building and increase the construction cost, thereby causing a problem of lowering the economical efficiency.
Disclosure of Invention
The present invention provides an impact absorbing device which can remarkably reduce interlayer noise of a building by effectively absorbing impact and thereby ensure a quiet living environment, and a floor structure of a building which can block interlayer noise by the impact absorbing device.
In order to achieve the above object, the present invention provides an impact absorbing device capable of elastically absorbing impact and a structure for reducing interlayer noise by applying the impact absorbing device to a floor of a building during construction.
The invention can reduce interlayer noise obviously and construct a building which can ensure a quiet living environment.

Detailed Description
The invention provides an impact absorption device and application thereof in an interlayer noise barrier structure. Next, the present invention will be described in detail with reference to fig. 1 to 7.
First, the impact absorbing device will be explained. Fig. 1 is an explanatory view of an impact absorbing device to which the present invention is applied, fig. 2 is an exploded view of an impact absorbing device to which the present invention is applied, and fig. 3 is a sectional view of an impact absorbing device to which the present invention is applied.
As shown in the drawings, the shock absorbing device to which the present invention is applied includes an upper tube 120 having a hollow interior and an inlet opening to the lower side, and a lower tube 140 coupled to the upper tube 120, and the lower tube 140 can be advanced and retracted in a state in which a part thereof is fitted into the upper tube 120, thereby extending and contracting the length thereof. The lower cylinder 140 may be hollow and may have an inlet opening upward, as in the upper cylinder 120.
A support plate 122 may be formed at the outer circumference of the upper cylinder 120. May be formed in the lower portion. In addition, a coupling protrusion 102 may be formed at an upper end of the upper cylinder 120. The coupling protrusion 102 may be formed at the upper end of the main body 100 by forming the coupling protrusion 102 at the upper end of the upper cylinder 120.
In the interior of at least one of the upper and lower cartridges 120 and 140, an elastic support column 160 may be formed in a transverse direction. Elastomeric support columns 160 are formed on upper column 120 at a spaced location from the upper surface, and on lower column 140 at a spaced location from the interior floor.
Elastomeric support columns 160 are formed in such a way that elastic contraction and expansion can occur while sufficiently ensuring their strength, and may be formed using steel wires as shown. A plurality of steel wires may be provided and both ends thereof may be firmly fixed to the edges of the upper and lower cylinders 120 and 140, respectively, and in this case, the steel wires may be installed to penetrate the center of gravity in the direction of the interface between the upper and lower cylinders 120 and 140. Whereby, in the case of forming elastomeric support columns 160 from a plurality of steel wires, the steel wires will be formed to intersect through the center of gravity and thereby form a shape in which the steel wires are radially spread out from the center of gravity.
Furthermore, elastomeric support columns 160 may be formed using, for example, metal mesh, metal plates, plastic plates, etc., in addition to steel wires. Any structure may be used as long as it can elastically deform while supporting an external force and thereby absorb an impact.
The impact absorbing apparatus to which the present invention is applied includes a conductor 180 installed inside the body 100. Conductors 180 are supported by elastomeric support columns 160. In the case where the elastic support columns 160 are formed on the upper cylinder 120, the upper ends will contact the elastic support columns 160 and the lower ends will contact the bottom surface inside the lower cylinder 140, in the case where the elastic support columns 160 are formed on the lower cylinder 140, the upper ends will contact the upper surface of the upper cylinder 120 and the lower ends will contact the elastic support columns 160, and in the case where the elastic support columns 160 are formed on both the upper cylinder 120 and the lower cylinder 140, the upper ends and the lower ends will contact the elastic support columns 160.
The conductive body 180 formed in the above-described manner may transmit an impact to the elastic support columns 160 when the upper cartridge 120 is impacted. As a result, elastomeric support columns 160 will elastically deform and absorb the impact. In the above process, the lower cylinder 140 enters the inside of the upper cylinder 120 and contracts the length of the body 100, and returns the extension to the original length after absorbing the impact, thereby achieving the impact absorption.
The conductor 180 may be formed in a pillar shape. Further, the elastic member may be formed of a rubber material having elasticity. In the above-described constitution, the groove 182 is formed at a position contacting with the steel wire so that the steel wire is inserted into the groove 182. Thereby, a stable mounting state of the conductor 180 can be ensured.
The through-hole 104 may be formed in at least one of the upper tube 120 and the lower tube 140. A plurality of through holes 104 may be formed, and air may be circulated between the inside and outside of the main body 100 in the process of the main body 100 expanding and contracting in response to the impact by the above-described configuration. This ensures smooth expansion and contraction of the main body 100.
In addition, the inside of the main body 100 may be filled with a sound absorbing material. The sound-absorbing material as described above can absorb noise generated during the process of absorbing impact by the main body 100.
Further, the upper cylinder 120 and the lower cylinder 140 may be coupled in such a manner that they are not separated during the expansion and contraction process. This can be achieved by applying silicone having elasticity at a certain interval at a position where the upper cylinder 120 and the lower cylinder 140 are connected, but is not limited thereto, and any structure may be used as long as it can expand and contract without separation.
Fig. 4 is an explanatory view for explaining a state where the shock absorbing device to which the present invention is applied absorbs a shock.
The impact absorbing apparatus to which the present invention is applied may allow the upper cylinder 120 to enter the lower cylinder 140 and thereby contract the length of the body 100 when subjected to a load. When the upper tube 120 receives a load while the lower tube 140 is supported, the upper tube 120 is lowered and shortened, and thus the elastic support columns 160 are pressed by the conductive bodies 180 and elastically deformed, thereby supporting the load. I.e. elastically absorbing the impact.
Fig. 5 is a diagram of another embodiment of a conductor to which the present invention is applied.
As shown in the drawing, the conductor 180 to which the present invention is applied may be formed in a spherical shape. May be formed of a material having elasticity such as rubber and supported by the elastic support columns 160.
Fig. 6 is a diagram of another embodiment of an impact absorbing device to which the present invention is applied.
As shown in the drawing, an impact absorbing device to which the present invention is applied may form the elastic support columns 160 only on the lower cylinder 140. In the case described above, the upper end of the conductor 180 will be in surface contact with the interior upper portion of the upper barrel 120, while the lower end will be supported by the elastomeric support columns 160. Although not shown, it may be formed on only the elastic support columns 160 instead.
Next, a structure for blocking interlayer noise by the impact absorbing device to which the present invention is applied as described above will be described. Fig. 7 is an explanatory view showing a floor structure to which the impact absorbing device of the present invention is applied, and is a state in which the impact absorbing device to which the present invention is applied to a floor structure of a building.
As shown in the drawings, the interlayer noise insulation structure to which the present invention is applied is to install an impact absorbing device to which the present invention is applied between a concrete base 600 and an indoor floor layer 400 formed at a certain interval on an upper side of the concrete base 600. A space may be formed between the concrete foundation 600 and the indoor floor layer 400, and the impact absorbing device bodies 100 may be installed at certain intervals on the space.
The interior floor layer 400 may include a panel 420. The panel 420 may be formed using plastic or wood, and may be formed in a thickness that can sufficiently withstand a load. The panel 420 may function to allow it to perform a corresponding work in case that the indoor floor layer 400 is formed by pouring cement mortar.
The insulation layer 200 is formed on the lower side of the indoor floor layer 400. This may be formed by installing an insulation panel having a certain thickness, and when the panel 420 is formed on the indoor floor layer 400, it is formed under the panel 420.
In the above-described configuration, the upper portion of the shock absorbing device body 100 to which the present invention is applied penetrates the heat insulating layer 200. Preferably, only the upper cylinder 120 of the main body 100 is partially penetrated. Accordingly, the insulation layer 200 may be formed as long as the height from the concrete foundation 600 to the indoor floor layer 400 is the same as the height of the main body 100, and thus the height of the indoor floor layer 400 may not be changed even when the insulation layer 200 is formed. In the above-described construction, the upper end of the main body 100 is brought into contact with the indoor floor layer 400, whereby it is possible that the impact applied to the indoor floor layer 400 is directly transmitted to the main body 100.
Wherein, the coupling protrusion 102 formed at the upper end of the main body 100 is formed at a certain height from the center of the main body 100 and is embedded into the indoor floor layer 400. And in the case where the panel 420 is formed in the indoor floor layer 400, it is embedded in the panel 420. The embedding may be performed in a screw coupling manner by using a screw structure. Thereby, the position of the body 100 can be firmly fixed.
In the structure in which the adiabatic layer 200 is formed as described above, the support plate 122 formed at the outer circumference of the upper cylinder 120 supports the lower end of the adiabatic layer 200, thereby helping the adiabatic layer 200 to maintain a stable state.
Further, a vibration-proof rubber 500 may be mounted on the lower end of the main body 100. May be formed in a plate shape having a certain thickness, and may serve to prevent vibration or noise from being transmitted to the concrete foundation 600 when the main body 100 operates. The vibration damping rubber 500 may be formed of other materials that can perform the same function and function, instead of using a rubber material.
By the interlayer noise insulation structure to which the present invention is applied as described above, impact generated during indoor life can be transmitted to the main body 100 through the indoor floor layer 400, whereby the main body 100 can be restored to an original position after slight contraction occurs as described above with reference to fig. 4, thereby softly absorbing the impact. Therefore, the noise between floors can be effectively relieved.
