Description

Impact and noise attenuation device, method of manufacturing the same, and floating floor structure

Technical Field

The present invention relates to an impact and noise attenuating device, a method of manufacturing the same, and a floating floor structure using the same.

Background

Recently, with the development of industrial technology and the improvement of living standards, there is an increasing demand for preventing or reducing noise caused by mechanical devices and interlayer noise.

On the other hand, in modern society, as the number of automobiles increases, the number of waste tires increases, and the environmental pollution problem and disposal cost caused by the waste tires also increase. However, scrap tires are difficult to dispose of and are not sufficiently recycled.

As a method for simultaneously solving the above problems, an apparatus and method for attenuating impact and noise using a waste tire chip have been developed.

However, all of these devices or methods are used by bonding crushed waste tire chips with an adhesive, which causes the following problems.

Adhesives from waste tire chips release hazardous substances that are hazardous to health, thus limiting indoor use.

Further, since the waste tire chips are adhered to each other by the adhesive, the elasticity of the waste tire chips themselves is reduced, and at the same time, the elastic deformation of the waste tire chips is suppressed by the cured adhesive, so that the elasticity is deteriorated.

Further, the waste tire core pieces adhered by the adhesive are damaged by repeated impacts, thereby decreasing durability, and fine dust and the like are released.

Further, in the case where the waste tire core pieces themselves are to be used as elastic members without an adhesive, there is no device or technique to properly exert the elastic force of the waste tire core pieces.

Detailed Description

Hereinafter, some embodiments of the present invention will be described in detail with reference to the exemplary drawings. In the drawings, like reference numerals are used to designate like elements throughout the figures, and even though shown in different drawings have like symbols. In the following description of the embodiments of the present invention, a detailed description of related well-known structures or functions is omitted when it may obscure the embodiments of the present invention.

In describing the components of embodiments of the present invention, the terms first, second, a, B may be used. These terms are used to distinguish one element from another, and the terms do not limit the nature or order of the elements. When an element is described as being "connected," "coupled," or "coupled" to another element, the element may be directly connected to the other element or may be "connected," "coupled," or "coupled" between the respective elements.

An impact and noise attenuating apparatus, a method of manufacturing the same, and a floating floor structure using the same according to embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1, the impact and noise attenuating apparatus according to the embodiment of the present invention prevents or attenuates vibration or noise caused by external impact. The present embodiment may include an elastic member 10 formed by gathering a plurality of elastic chips and an elastic container 20 for enclosing the elastic member 10 after compression. This embodiment can also be used for mechanical devices other than floating floor structures of apartments.

The elastic member 10 is a simple aggregate of elastic chips, and does not contain an adhesive. The elastic member 10 absorbs an impact by elastic contraction of the elastic chips themselves corresponding to the external impact, and after filling the gap between the elastic chips, returns to the filled gap as the elastic chips expand, thereby preventing or attenuating vibration or noise caused by the external impact.

The elastic chips do not adhere as an adhesive, but rather serve as a simple aggregate of elastic chips. Therefore, leakage of harmful substances flowing out of the adhesive is prevented, and thus it can be used indoors. Further, elastic deformation of the elastic chip due to adhesion of the adhesive and suppression of elastic deformation due to the cured adhesive are prevented. Therefore, the elastic force of the elastic chip is maintained without reducing the elastic force. In addition, fine dust and the like generated by breakage of the adhesive-bonded elastic chip due to repeated impact are remarkably reduced.

The elastic core pieces constituting the elastic member 10 may be used as waste tire core pieces made by cutting waste tires. By using the waste tire core, environmental problems can be solved and costs can be reduced.

The elastic chip may be composed of at least one selected from a waste tire chip, a rubber chip, and an SEBS chip (styrene ethylene butylene styrene). Namely, the rubber tire is composed of a waste tire chip, a rubber chip or an SEBS chip or a mixture of more than two of the waste tire chip, the rubber chip or the SEBS chip. The SEBS chip is thermoplastic rubber, and can show rubber performance only through physical stirring without vulcanization. SEBS is a high-performance elastomer such as rubber, and is classified into styrene type, lipophobic type, PVC type, polyamide type, and the like.

The elastic chip may further include at least one selected from a PP (polypropylene) chip, a PE (polyethylene) chip, a plastic chip, and a wood chip. For example, the waste tire chip may further include at least one chip selected from a PP chip, a PE chip, a plastic chip, a wood chip, or the mixture of the waste tire chip and the rubber chip may further include at least one chip selected from a PP chip, a PE chip, a plastic chip, a wood chip. By mixing chips having different materials as described above, the elastic force required for the impact is obtained. That is, when a large elastic force is required, a large number of chips having a large elastic force may be used, and when a small elastic force is required, a large number of chips having a small elastic force may be used. In addition, the mixing of the chips may be mixed in consideration of cost in the case where the same elastic force is required. That is, as low cost flexible chips as possible are used.

In addition, the elastic core may use particles having the same size or a mixture of particles having different sizes. In the case of the same size, the elastic chip is not inserted between other elastic chips, so that the aperture is large, resulting in large elastic deformation. Therefore, smooth and gentle elasticity can be exhibited. On the other hand, when the large elastic chips and the small elastic chips are used in combination, the small elastic chips are interposed between the large elastic chips, so that the space between the elastic chips is small and the elasticity is large.

In addition, the elastic chip can also comprise at least one of fine rice flour, wheat flour, barley flour and charcoal powder. Such fine powder of rice flour or the like can reduce friction and prevent breakage or abrasion of the elastic chip. In addition, when rice flour or the like is filled in the voids of the elastic chip, deformation of the elastic chip is suppressed, and thus the elastic force can be controlled. In particular, charcoal powder adsorbs and decomposes pollutants and harmful substances in the air to purify the air, remove offensive odors, and adjust humidity by absorbing or releasing moisture.

The elastic member 10 may include a sound absorbing material 12 on the upper side or/and the lower side of the plurality of elastic chips. That is, the sound absorbing material 12 may be disposed on the upper side of the elastic core, or the sound absorbing material 12 may be disposed on the lower side of the elastic core, or the sound absorbing material 12 may be disposed on the upper and lower sides. When the sound-absorbing material 12 is included as described above, noise from the outside can be absorbed, and at the same time, noise generated in the impact and noise attenuating device itself can be absorbed.

In addition, the sound-absorbing material 12 may be put in the compression adjustment container 60 before or after the elastic chip, or both before and after the elastic chip is put in the compression adjustment container 60. The sound-absorbing material 12 maintains the shape of the compression-adjusting container 60 while the elastic chips are dropped, and the elastic chips are not scattered outward, so that the elastic chips are dropped very conveniently. The sound absorbing material 12 may be a polyester material or the like having a sound absorbing effect.

The elastic container 20 prevents the elastic chip from leaking to the outside, and binds the elastic chip to elastically resist the impact acting on the elastic container 20. That is, the elastic container 20 prevents the elastic chip from leaking from the elastic container 20 when an impact is applied, and elastically contracts the elastic chip to absorb the impact.

The elastic container 20 may be made of plastic, PE, PP, iron, etc., but any one may repeatedly sufficiently bear a load or impact, and may restrain the elastic chip in correspondence to the load or impact.

The elastic container 20 includes a bottom plate 21, a body 23 coupled to an upper side of the bottom plate 21, and a pressing member 23 provided on the body 23 to transmit an external impact to the elastic member 10.

The bottom plate 21 is provided at the bottom and formed in a circular, square, hexagonal shape, and the body 23 may be coupled to the upper side.

A locking piece for coupling with the body 23 is provided on the upper side of the bottom plate 21. That is, the engaging piece is formed in the circumferential direction on the bottom plate 21 formed of a simple flat-plate-shaped horizontal portion, or a vertical portion having a low height such as a hollow cylinder, a square column, or a hexagonal column is coupled to the horizontal portion of the bottom plate 21, and the engaging piece is formed on the vertical portion of the bottom plate 21.

The base plate 21 may be formed with a screw at an inner or outer side of the vertical portion, and the screw may be combined with a screw formed at an outer or inner side of a lower portion of the body 23.

In addition, the bottom plate 21 may be adhered to the main body 23 with an adhesive or the like or welded to the main body 23.

The body 23 is coupled to an upper side of the bottom plate 21 and formed in a hollow cylindrical shape, i.e., a cylindrical, square cylindrical, hexagonal cylindrical, etc. shape, and forms a through hole 231 whose lower side is open at a central portion of the upper side. The body 23 accommodates the elastic member 10 inside, and then contracts and expands inside, and prevents leakage to the outside.

The compression member 25 is disposed at an upper side of the body 23 and can vibrate up and down in response to an external impact while transmitting the external impact to the elastic member 10.

That is, the compression member 25 is provided inside the body 23 and on the upper side of the elastic member 10, and may be constituted only by a compression plate 251 to be described later. In this case, the external impact is transmitted to the compression plate 251 through the through-hole 231 of the central portion of the body 23, and the compression plate 251 transmits the impact to the elastic chip while vibrating up and down.

The compression member 25 includes a compression plate 251 disposed inside the body 23 and on an upper side of the elastic member 10, a neck 253 formed on the upper side of the compression plate 251, the neck 253 protruding toward an upper side of the through-hole 231 of the body 23.

The compression plate 251 prevents the elastic chip from flowing out toward the upper side through the through-hole 231 by blocking the through-hole 231, and vibrates up and down in response to an external impact applied from the upper side to transmit the impact to the elastic member 10. An air hole 233 may be formed in the main body 23 so that the elastic member 10 can be easily extended and contracted.

The neck 253 is coupled to the compression plate 251, and protrudes from an upper side of the through-hole 231. The neck 253 may be integrally formed with the compression plate 251 or separately formed and then coupled. The neck 253 transmits external impact to the compression plate 251 or supports a later-described bracket 40. The height of the neck 253 is determined in consideration of the degree to which the elastic member 10 is stretched and contracted and the bracket 40 provided on the neck 253.

Referring to fig. 2, the neck 253 may be a cylindrical shape filled inside, or a hollow cylindrical shape with a screw formed at an inner side, or a plurality of support plates disposed to be spaced apart from each other in a circumferential direction.

The neck 253 may have a hollow cylindrical shape, and may be formed with a screw on the surface. In this case, a cylindrical bracket 40 whose height is adjusted by rotation in combination with the screw of the neck 253 may be further included. Accordingly, the bracket 40 is firmly coupled to the neck 253 by a screw formed at the outside, and the height can be adjusted as the bracket 40 is rotated.

The neck 253 may be formed in a hollow cylindrical shape, i.e., in a cylindrical shape, a triangular prism shape, a square prism shape, a hexagonal prism shape, or a plurality of support plates installed to be spaced apart in the circumferential direction. Therefore, the cylindrical bracket 40 may be disposed inside the neck 253 so as not to be inclined or disengaged.

As shown in fig. 3a to 3i, the support portion 50 may be disposed at an upper side of the neck portion 253 or at an upper side of the bracket 40. That is, the support 50 may be attached to the upper side of the bracket 40 when the bracket 40 is provided, or may be attached to the upper side of the inner pillar shaped neck 253 when the bracket 40 is not provided.

The support portion 50 is formed with a groove for inserting the square bar 58 at an upper side so that the square bar 58 can be supported. The planar shape of the support portion 50 may be a shape like a letter-o, a shape like a right-angled letter, an ┰ shape, a + shape, or the like. The positive support portion 50 is mainly formed in the center of the blank, the right-angled support portion 50 is provided in the corner of the blank, and the ┰ -shaped support portion 50 is provided in the edge of the blank. The square bars 58 may be installed in the upper grooves of the support 50 in a lattice shape. In addition, bolt holes are formed in the support portion 50 to be coupled with the square bar 58.

As shown in fig. 3e to 3i, the support portion 50 includes a plurality of horizontal portions 51 extending from the center to the outer side of the body 23, vertical bent portions 53 bent downward from the respective plurality of horizontal portions 51, horizontal bent portions 54 bent in the horizontal direction from the vertical bent portions 53, and hook portions 56 for connecting the vertical bent portions 53 and the horizontal bent portions 54. The square bar 58 is inserted into and supported by a space where the vertical bent portion 53, the horizontal bent portion 54, and the hook portion 56 are formed, so that the square bar 58 can be stably supported. At this time, an auxiliary hook for connecting between the horizontal portion 51 and the vertical bent portion 53 is further included, and the auxiliary hook increases the strength of the support portion 50 to more stably support the square bar 58.

The curved portion 65 is coupled to the lower end portion of the body 23, or the compression adjustment container 60 is provided inside the body 23, so that the elastic member 10 is effectively thrown into the body 23.

The bent portion 65 and the compression-adjusting container 60 allow the elastic member 10 to be easily compressed and inserted into the elastic container 20, and prevent the detachment of the elastic chip until the body 23 is coupled with the base plate 21.

Preferably, the bending part 65 is coupled to a lower end of the body 23 and is flexibly bent. The bent portion 65 is bent inward when pressed by the bottom plate 21 to prevent the elastic chip from being separated from the outside of the body 23. After the elastic chip is completely compressed, it is held in a bent state inside the body 23. The bent portion 65 may be formed integrally with the body 23, or may be joined by adhesion or the like after being manufactured separately from the body 23.

The height of the bent portion 65 depends on the degree of compression of the elastic chip. That is, when the elastic chip is to be compressed greatly, the height of the bent portion 65 is increased, and when the elastic chip is to be compressed slightly, the height of the bent portion 65 is decreased.

Further, the bent portion 65 may have a plurality of cutout portions 651 formed in the vertical direction. The cutout portion 651 allows the bent portion 65 to be bent well. Further, an inclined cutout 653 may be formed outside the lower end portion of the curved portion 65. The inclined cutout portion 653 makes the curved portion 65 easily curve inward.

In the case where the bent portion 65 is coupled to the body 23, the impact and noise attenuating device is manufactured as follows. The body 23 is turned upside down so that the bent portion 65 is positioned at the upper side, and the compression member 25 is inserted so that the neck portion 253 protrudes downward through the through hole 231 of the body 23, and after the elastic member 10 is inserted inside the body 23 and the bent portion 65, the elastic member 10 and the bent portion 65 are pressed together toward the bottom plate 21 to be coupled to the body 23.

The compression-adjusting container 60 allows the elastic member 10 to be easily compressed and inserted into the elastic container 20, and prevents the elastic chip from being separated until the body 23 and the base plate 21 are combined. The compression adjusting container 60 may be provided with an air hole.

The compression adjusting container 60 may be formed in the same shape as the body 23, such as a hollow circular shape, a square shape, a hexagonal shape, etc. opened at the upper and lower sides, or may be unfolded in a circular shape, a square shape, a hexagonal shape, etc. when used in a folded state of an envelope.

The length of the compression-adjusting container 60 is longer than that of the body 23, and is determined according to the degree of compression of the elastic member 10. That is, when the elastic member 10 is greatly compressed, the length of the compression adjustment container 60 is longer than the set, and when the elastic member 10 is slightly compressed, the compression adjustment container 60 is shortened.

Further, the compression adjusting container 60 may be manufactured in a state of being cut into a necessary length in advance, or may be cut for use when being used after being formed as a single body. In any case, since the body 23 and the compression-adjusting container 60 are separately manufactured, it is easy to manufacture the body 23 and the compression-adjusting container 60, and the compression-adjusting container 60 conforms to the amount of compression.

In the case where the compression adjusting container 60 is provided inside the body 23, the impact and noise attenuating apparatus may be manufactured as follows. The body 23 is turned upside down and the compression member 25 is inserted into the through hole 231 of the body 23 such that the neck 253 protrudes downward, the compression-adjusting container 60 is installed inside the body 23, and after the elastic member 10 is thrown inside the compression-adjusting container 60, the elastic member 10 and the compression-adjusting container 60 are pressed together with the bottom plate 21 to be coupled to the body 23.

Preferably, the bending part 65 and the compression-adjusting container 60 are not bent until the elastic member 10 is compressed, and the elastic member 10 is not scattered. Meanwhile, when pressed by the bottom plate 21, it is preferable to be easily deformed together with the elastic member 10. That is, the impact and noise attenuating apparatus of the present embodiment increases the elastic force by compressing the shot elastic member 10, instead of just shooting the elastic member 10.

The bending part 65 and the compression adjusting container 60 have a certain degree of rigidity such as paper, vinyl, PP (polypropylene), etc. so as to be easily inserted, i.e., not to be bent or deformed during the putting of the elastic chip, preferably to prevent the elastic chip from falling off when simultaneously pressed by the bottom plate 21, and also to be easily bent so as to compress the elastic member 10. However, when the bent portion 65 is integrally formed with the main body 23, it is preferable that the main body 23 has the same material as the bent portion 65.

Referring to fig. 4a to 4c, the impact and noise attenuating apparatus according to the embodiment of the present invention may be applied to a floating floor structure of a house.

That is, a plurality of the above-mentioned impact and noise attenuating devices are arranged on the floor in a lattice form, and the necks 253 of the plurality of impact and noise attenuating devices arranged in the lattice or the upper sides of the brackets 40 are connected, and after the floor mounting guides 70 are installed in a rectangular shape, the floor is installed between the upper sides of the floor mounting guides 70. Therefore, the floor can be stably supported between the floor installation guides 70.
