Description

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

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

  On the other hand, in the modern society, the number of waste tires has increased rapidly due to the increase in automobiles, and the problem of environmental pollution and processing costs due to the waste tires has also greatly increased. However, compared with this, it is difficult to dispose of the waste tire and recycling is insufficient.

  As a method for solving such a problem at the same time, an apparatus and a method for attenuating impact and noise using a waste tire chip have been developed.

  However, all of such apparatuses and methods use waste tire chips obtained by pulverizing waste tires in combination with a binder, which has the following problems.

  Use in indoors is limited because harmful substances are released by binders that bind waste tire chips and are harmful to health.

  Further, when the waste tire chips are mutually coupled by the binder, the elastic force of the waste tire chips themselves is reduced, and the elastic deformation of the waste tire chips is suppressed by the hardened binder, thereby reducing the elastic force.

  In addition, the waste tire chip bonded with the binder is damaged by repeated impacts and the durability is lowered, and fine dust and the like are released.

  Further, when the waste tire chip itself is to be used as an elastic member without a binder, there is no device or technology for successfully exerting the elastic force of the waste tire chip.

  Hereinafter, some embodiments of the present invention will be described in detail based on exemplary drawings. In adding reference numerals to the constituent elements of each drawing, the same constituent elements have the same reference numerals as much as possible even if they are displayed on other drawings. Further, in describing the embodiment of the present invention, when it is determined that a specific description of a related known configuration or function hinders understanding of the embodiment of the present invention, the detailed description thereof is omitted.

  In describing the components of the embodiment of the present invention, terms such as first, second, A, B, (a), and (b) can be used. These terms are merely for distinguishing one component from other components, and do not limit the essence, order, order, or the like of the corresponding component. When a component is described as being “coupled”, “coupled” or “connected” to another component, the component may be directly coupled or connected to other components, It is to be understood that another component may be “coupled”, “coupled” or “connected” between the components.

  Hereinafter, an impact and noise attenuating device according to an example of the present invention, a manufacturing method thereof, and an apartment house floating floor structure using the same will be described in detail with reference to the accompanying drawings.

  Referring to FIG. 1, an impact and noise attenuating apparatus according to an example of the present invention prevents or attenuates the generation of vibration and noise due to externally applied impact. The present embodiment may include an elastic member 10 configured by collecting a large number of elastic chips, and an elastic container 20 that compresses and stores the elastic member 10. The present embodiment can be used for a mechanical apparatus or the like in addition to the apartment house floating floor structure.

  The elastic member 10 is a simple assembly of elastic tips and does not contain a binder. When the elastic member 10 is elastically contracted in response to an impact from the outside and the gap between the elastic chips is filled, the elastic chip expands again, and at the same time, the filled gap is restored. To absorb. This prevents or attenuates vibrations and noise generated from external impacts.

  The elastic tip is not bonded with a binder and is used as a simple assembly of elastic tips. Therefore, since harmful substances flowing out from the binder are prevented from flowing out, they can be used indoors. Further, it is possible to prevent elastic deformation of the elastic tip due to the binding of the binder and suppression of elastic deformation due to the cured binder. Therefore, the elastic force does not decrease and the elastic force of the elastic tip is maintained as it is. In addition, the fine dust generated when the elastic tip bonded with the binder is damaged by repetitive impacts is remarkably reduced.

  As the elastic chip constituting the elastic member 10, a waste tire chip produced by cutting a waste tire into small pieces can be used. By using the waste tire chip, it is possible to solve environmental problems and reduce costs.

  In addition, the elastic tip can be composed of at least one selected from waste tire tips, rubber tips, and SEBS (styrene butylene styrene). That is, it can be composed of waste tire chips, rubber chips or SEBS chips, or a mixture of two or more of these. The SEBS chip is a thermoplastic rubber, and is a synthetic resin that exhibits rubber-like properties only by physical stirring without vulcanization. This SEBS is a high-performance elastic body similar to rubber, and is classified into styrene, olefin, PVC, and polyamide.

  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 further includes at least one chip selected from a PP chip, a PE chip, a plastic chip, and a wood chip, or a mixture of the waste tire chip and the rubber chip includes a PP chip, a PE chip, and a plastic chip. And at least one chip selected from wood chips. Mixing chips of different materials in this way is advantageous in obtaining the elastic force necessary for impact. That is, when a large elastic force is required, a large number of chips having a large elastic force can be used, and when a small elastic force is required, a large number of chips having a small elastic force can be used. Further, these chips can be mixed in consideration of cost in the situation where the same elastic force is required. That is, it is possible to use an elastic tip having a low cost within a possible limit.

  In addition, the elastic tip may use particles having the same size, or may be used by mixing particles having different sizes. When the sizes are the same, the elastic chip is not mixed between the other elastic chips, so that the gap is large, and as a result, the elastic deformation is increased. Therefore, the elastic force can be exerted smoothly and softly. On the other hand, when a large elastic chip and a small elastic chip are mixed and used, the small elastic chip is mixed in the large elastic chip and the gap between the elastic chips is small, so that the elastic force is large.

  Moreover, at least 1 sort (s) of fine rice flour, wheat flour, barley flour, and charcoal powder can further be included in an elastic chip. This fine rice flour can reduce the frictional force and prevent the elastic tip from being damaged or worn. Further, when rice powder or the like is filled in the gap of the elastic chip, the deformation of the elastic chip is suppressed, and the elastic force can be adjusted thereby. In particular, charcoal adsorbs pollutants and harmful substances in the air, decomposes and purifies the air, removes odors, and absorbs or releases moisture to regulate humidity.

  The elastic member 10 can include a sound absorbing material 12 on the upper side and / or the lower side of a large number of elastic chips. That is, the sound absorbing material 12 can be provided on the upper side of the elastic chip, the sound absorbing material 12 can be provided on the lower side of the elastic chip, or the sound absorbing material 12 can be provided on both the upper side and the lower side. Thus, when the sound absorbing material 12 is included, it is possible to absorb noise from the outside and also to absorb noise generated from the impact and noise attenuation device itself.

  The sound absorbing material 12 can be put into the compression adjusting container 60 described later before the elastic tip, after the elastic tip, or both the front and rear. The sound absorbing material 12 is very convenient for the insertion of the elastic chip by maintaining the shape of the compression adjusting container 60 when the elastic chip is inserted and at the same time preventing the elastic chip from being scattered outside. . As the sound absorbing material 12, a material having a sound absorbing effect, such as polyester, can be used.

  The elastic container 20 prevents the elastic chip from flowing out, and binds the elastic chip so that the elastic chip elastically resists in response to an impact acting on the elastic container 20. That is, the elastic container 20 absorbs the impact by preventing the elastic tip from flowing out of the elastic container 20 and causing the elastic tip to contract when the impact is applied.

  The elastic container 20 may be made of plastic, PE, PP, iron, etc., but all of them can sufficiently support loads and impacts that repeatedly act, and elastic tips can be used in response to the loads and impacts. Must be able to unite.

  The elastic container 20 may include a bottom plate 21, a body 23 coupled to the upper side of the bottom plate 21, and a compression member 25 that is provided on the upper side of the body 23 and transmits an external impact to the elastic member 10.

  The bottom plate 21 is installed on the lowermost side, and is formed in a shape such as a circle, a square, or a hexagon, and the body 23 can be coupled to the upper side.

  On the upper side of the bottom plate 21, a locking tool for coupling the body 23 may be provided. That is, only the locking member is formed along the circumferential direction on the bottom plate 21 composed of a simple flat horizontal portion, or the horizontal portion has a low height, such as a hollow columnar shape, a quadrangular column shape, or a hexagonal column shape. A locking member can be formed on the vertical portion of the bottom plate 21 to which the two are connected.

  Further, the bottom plate 21 forms a screw inside or outside the vertical portion, and this screw can be coupled with a screw formed outside or inside the lower portion of the body 23.

  Further, the bottom plate 21 can be bonded to the body 23 with an adhesive or the like, or can be welded.

  The body 23 is coupled to the upper side of the bottom plate 21 and is formed in the shape of a hollow column, that is, a cylinder, a square column, a hexagonal column, the lower side is opened, and the upper side is drilled in the central part. The through-hole 231 can be provided. The body 23 accommodates the elastic member 10 in the inside thereof, and then enables contraction and expansion inside, and at the same time prevents outflow to the outside.

  The compression member 25 is provided on the upper side of the body 23 and can transmit an external impact to the elastic member 10 while vibrating up and down in response to the external impact.

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

  In addition, the compression member 25 is inside the body 23 but is provided on the upper side of the elastic member 10, and the neck portion 253 that is coupled to the upper side of the compression plate 251 and protrudes above the through-hole 231 of the body 23. And can be configured.

  The compression plate 251 blocks the through-hole 231 to prevent the elastic chip from flowing out upward through the through-hole 231 and vibrates up and down in response to an external impact applied from above. Transmit impact. An air hole 233 can be formed in the body 23 for easy expansion and contraction of the elastic member 10.

  The neck portion 253 is coupled to the compression plate 251 and protrudes above the through hole 231. The neck 253 may be formed integrally with the compression plate 251 or may be formed after being formed separately. The neck 253 transmits an external impact to the compression plate 251 or supports a stationary table 40 described later. The height of the neck portion 253 is determined in consideration of the extent to which the elastic member 10 expands and contracts, the table 40 installed on the neck portion 253, and the like.

  Referring to FIG. 2, the neck 253 has a solid column shape, a hollow column shape, a hollow column shape, a screw formed inside, or spaced apart from each other along the circumferential direction. A plurality of support plates.

  The neck portion 253 can be formed with a screw on its inner surface while being a hollow cylindrical shape. In this case, it may further include a columnar table 40 that is coupled to the screw of the neck 253 and whose height is adjusted by rotation. Thus, the gantry 40 is threaded on the outer surface and is firmly coupled to the neck 253 and can be adjusted in height as it rotates simultaneously.

  The neck portion 253 may be formed in a hollow columnar shape, that is, a columnar shape, a triangular column shape, a quadrangular column shape, a hexagonal column shape, or the like, or a plurality of support plates may be provided along the circumferential direction. Therefore, the columnar table 40 is installed inside the neck portion 253 and does not tilt or separate.

  Referring to FIGS. 3 a to 3 i, the support portion 50 can be installed on the upper side of the neck portion 253 or the upper side of the stationary table 40. In other words, the support unit 50 can be provided above the installation table 40 when the installation table 40 is provided, and the support unit 50 can be provided above the solid columnar neck 253 when the installation table 40 is not provided.

  The support part 50 is formed in a shape having a groove into which the square member 58 is fitted on the upper side, and can support the square member 58. The planar shape of the support portion 50 can be various shapes such as a single letter shape, an L shape, a T shape, and a cross shape. The cross-shaped support part 50 is mainly installed in the middle of the slab, the L-shaped support part 50 is installed at the corner of the slab, and the T-shaped support part 50 is installed at the end of the slab. Square members 58 can be installed in a lattice pattern in the upper grooves of these support portions 50. Further, a vault hole can be drilled in the support portion 50 and coupled to the square member 58.

  Referring to FIGS. 3e to 3i, the support part 50 includes a plurality of horizontal parts 51 extending from the center thereof to the outside of the body 23, a vertical bent part 53 bent downward from each of the plurality of horizontal parts 51, and A horizontal bent portion 54 bent in the horizontal direction from the vertical bent portion 53 and a haunch portion 56 connecting the vertical bent portion 53 and the horizontal bent portion 54 may be included. The square member 58 can be stably supported by inserting and supporting the square member 58 in the space formed by the vertical bent portion 53, the horizontal bent portion 54, and the haunch portion 56. In this case, an auxiliary hunch part that connects the horizontal part 51 and the vertical bent part 53 can be further included, and the auxiliary hunch part increases the strength of the support part 50 to support the square member 58 more stably. can do.

  In order to effectively put the elastic member 10 into the body 23, the bending portion 65 can be coupled to the lower end portion of the body 23, or the compression adjusting container 60 can be provided inside the body 23.

  The bent portion 65 and the compression adjusting container 60 allow the elastic member 10 to be easily compressed and loaded into the elastic container 20 and prevent the elastic chip from being detached until the body 23 and the bottom plate 21 are coupled.

  It is preferable that the bending part 65 is couple | bonded with the lower end part of the body 23, and is bent flexibly. When the bent portion 65 is pressed by the bottom plate 21, the elastic tip prevents the elastic tip from detaching to the outside of the body 23 while being bent inward, and after the elastic tip is completely compressed, the bent portion 65 is in a bent state. 23 inside. The bent portion 65 can be manufactured integrally with the body 23 or can be bonded separately after being manufactured separately from the body 23.

  The height of the bent portion 65 is determined according to the degree of compression of the elastic tip. That is, the height of the bent portion 65 is increased when attempting to compress the elastic tip greatly, and the height of the bent portion 65 is decreased when compressing the elastic tip small.

  Further, the bending portion 65 can form a plurality of incisions 651 in the vertical direction. This incision 651 allows the bending portion 65 to be bent well. In addition, an inclined cutout portion 653 can be formed outside the lower end portion of the bent portion 65. The inclined cut portion 653 allows the bent portion 65 to be bent inwardly.

  The impact and noise attenuation device when the bending portion 65 is coupled to the body 23 can be manufactured as follows. First, the body 23 is placed so that the bending portion 65 is located on the upper side, and the compression member 25 is inserted into the through-hole 231 of the body 23 so that the neck portion 253 protrudes downward. After the elastic member 10 is put inside the 65, the elastic member 10 and the bent portion 65 are pressed together by the bottom plate 21 and coupled to the body 23.

  The compression adjustment container 60 allows the elastic member 10 to be easily compressed and loaded into the elastic container 20 and prevents the elastic chip from being detached until the body 23 and the bottom plate 21 are coupled. An air hole may be formed in the compression adjustment container 60.

  The compression adjusting container 60 is formed with a length longer than that of the body 23 and is determined according to the degree of compression of the elastic member 10. In other words, the length of the compression adjustment container 60 is increased when a large amount of the elastic member 10 is to be compressed, and the length of the compression adjustment container is decreased when the elastic member 10 is to be compressed a little.

  The compression adjusting container 60 can be manufactured by cutting into a required length in advance, or once manufactured for a long time, it can be cut and used at the time of use. In any case, since the body 23 and the compression adjustment container 60 are manufactured separately, it is easy to manufacture the body 23 and the compression adjustment container 60, and the compression adjustment container 60 is prepared according to the required amount of compression. can do.
