Description

Floor structure panel for perventing noise between floors using vibration proof ball}

The present invention relates to a floor structure for preventing inter-floor noise using a vibration isolator, and more particularly, a cover protrusion in contact with the upper curved surface of the vibration isolator on the top of the fixed vibration isolator by inserting and fixing a vibration isolator on the coupling hole formed on the intermediate plate By placing the upper plate on which is formed, the vibration load is transmitted intensively. In particular, the vibration isolator can be easily placed in the intermediate plate coupling hole by the vibration isolator stepped to form a stepped jaw by forming different diameters of the upper hemisphere and the lower hemisphere, thereby reducing assembly time. In addition, the vibration absorption efficiency is increased by intensively transmitting the generated vibration load to the vibration isolator, such as improving the workability of the building floor by modularizing the middle plate and the upper plate, and the vibration isolator sandwiched between the middle plate and the upper plate through a coupling means. It relates to a floor structure for preventing interlayer noise.

Multi-storey apartment houses have become a social problem due to a lot of quarrels between neighbors due to noise between floors between the upper and lower floors. In recent years, most buildings are constructed with measures to block noise between floors.

General interfloor noise is noise pollution mainly generated in common residential spaces such as multi-family houses and apartments, such as the sound of children's running, footsteps, turning off furniture, or sound generated from electronic devices, and such interfloor noise is light and It can be divided into hard lightweight impact sound, heavy and high impact weight impact sound, and air transmission sound, which is a light sound transmitted through the aircraft.

As of 2012, according to the [Regulations on Housing Construction Standards, etc.], the floor impact sound between each floor is 58 decibels or less for the light impact sound (floor impact sound due to relatively light and hard impact), and 50 decibels for the heavy impact sound (floor impact sound due to heavy and soft impact). It stipulates that the structure should be as follows.

For these regulations, a sound insulating material, foamed concrete or styrofoam, and a mortar layer for piping a heating coil are sequentially stacked on the floor layer that divides the upper and lower layers of an apartment.

In the above structure, the noise depends on the sound insulating material. The sound insulating agent is effective in blocking sound, but there is no means for absorbing the noise generated by the impact vibration, so the interlayer noise removal effect is somewhat insufficient.

Korean Utility Model Registration No. 20-0386633 (registered on June 02, 2005; hereinafter referred to as'priority document 1') proposed a soundproof pad for preventing interfloor noise in multi-storey buildings. The Prior Document 1 includes a pad body having a dome-shaped buffer protrusion formed so as not to cross each other on the upper and lower surfaces, and is configured by placing a sound insulation plate thereon. The soundproof pad of Prior Literature 1 is to provide an effect of blocking a certain amount of impact vibration sound transmitted from the top by forming an air layer between the pad body and the buffer protrusion.

However, in the prior document 1, since the entire pad body is formed of a soft synthetic resin or a foamable synthetic resin material, elastic deformation is easily achieved when pressed. Therefore, when pressing from the upper part, the pressing force is simultaneously transmitted to the upper buffer protrusion and the lower buffer protrusion, but the upper buffer protrusion part is an empty space in the lower part and the upper part is an empty space. It is difficult to provide a noise-blocking effect by the air layer because the air layer is too thin or not formed therebetween. Of course, when the pad body material is formed of a hard material, each position is maintained to some extent to provide an air layer, but the cushioning effect due to elastic deformation is low, so the effect of blocking the impact vibration sound cannot be provided.

In addition, Prior Literature 1 describes that if a load is generated on either side of the upper part due to the material characteristics of the pad body, the load is concentrated on the corresponding part and the flatness of the upper surface may be lowered. Since there is no separate support means from the sound insulation plate, it is pushed in the horizontal direction, which may cause a tilting arrangement in one direction, so that it is biased when transferring a load, which further worsens the flatness of the upper surface.

Korean Utility Model Registration No. 20-0472109 (registered on March 31, 2014; hereinafter referred to as'priority document 2') proposed a cushion sheet for preventing inter-layer noise with an air layer. The prior document 2 is configured by fixing the anti-vibration rubber to the sheet at regular intervals with pins, and forming an air layer under the sheet by the anti-vibration rubber to provide a noise blocking effect.

The prior document 2 fixes the vibration-proof rubber to the sheet to prevent the phenomenon from being swung to one side, but the air layer is formed only as a single layer, so that the noise blocking efficiency is lower than that of the multi-stage air layer.

Korean Utility Model Registration No. 10-1586880 (registered on January 13, 2016, hereinafter referred to as'priority document 3') proposed a flooring material for preventing interfloor noise. The prior document 3 has a structure in which an upper plate and a lower plate are provided, and an elastic material buffer member is placed between the upper and lower layers to form an air layer between adjacent buffer members.

The prior document 3 also has a disadvantage of low noise blocking efficiency since the air layer is provided only as a single layer between the buffer members.

The purpose is to provide a floor structure material that can minimize the weight noise due to vibration load as well as increase the noise blocking effect by providing two air layers by the double floating floor structure.

In particular, the vibration load of the weight generated from the upper part is intensively transmitted from the top plate to the vibration isolator so that absorption is achieved in the vibration isolator, and part of it is transferred to the adjacent vibration isolator so that it is dispersed, so that the effective vibration load is reduced. can do.

In addition, the anti-vibration sphere of the present invention can be quickly coupled to the intermediate plate by forming a stepped jaw with different diameters of the upper hemisphere and the lower hemisphere, which is a modular work in which the upper plate and the intermediate plate are combined and integrated into one while the vibration is contained. It is to provide a floor structure material that can reduce the time and construction cost.

Floor structure for preventing inter-floor noise using the vibration isolator of the present invention for solving the above problems,

A floor structure material for preventing interlayer noise, comprising: an intermediate plate having coupling holes perforated at regular intervals; The diameter of the upper hemisphere is formed larger than the diameter of the coupling hole, the diameter of the lower hemisphere is formed similarly to the coupling hole, and has a spherical shape with a stepped in the middle, and a vibration damper for inserting and seating the lower hemisphere in the coupling hole of the intermediate plate; And an upper plate which is placed on the upper part of the dust-proof hole, and has a cover protrusion formed on the bottom surface at the same interval as that of the dust-proof hole, and the bottom surface of the cover protrusion interviews and supports the upper surface of the dust-proof hole.

In addition, in the lower hemisphere of the anti-vibration sphere, a fitting groove is further formed in an annular shape along a portion where a stepped jaw is formed, so that the edge of the intermediate plate coupling hole may be fitted.

In addition, a support hemisphere groove, which is a dome-shaped curved surface corresponding to the upper curved surface of the vibration isolator, is further formed on the bottom surface of the cover protrusion of the upper plate to increase a contact area with the vibration isolator.

In addition, it may be configured to include; coupling means for integrally coupling the intermediate plate and the upper plate while spaced apart at a predetermined interval.

Here, the coupling means may be formed in any one of a fitting type, a protrusion locking type, and a clip type.

In addition, the coupling means is formed as a pair of an arm coupling rod having a locking groove and a male coupling rod having a locking protrusion corresponding to the locking groove, and formed in a plurality of positions corresponding to each other on the intermediate plate and the upper plate. The intermediate plate, the vibration isolator, and the upper plate can be formed as an integrated module by extending and fastening.

In addition, the engaging means is composed of a locking hole formed through the intermediate plate, and a locking protrusion protruding downward from the bottom of the upper plate and a locking protrusion formed at the lower end through which the locking hole is inserted, and formed at a position corresponding to each other. Thus, it is possible to form an integrated module with the intermediate plate, the vibration isolator, and the upper plate by fastening.

In addition, the coupling means forms a shape of a plurality of clip portions on either side of the intermediate plate or the upper plate, and when in use, the clip portion is partially separated and the portion connected to the plate body is rotated with an axis to be vertically arranged, and the vertically arranged clip portion The intermediate plate and the upper plate with the vibration isolator are integrally combined with each other by fastening so as to be engaged with the other intermediate plate or the upper plate opposite to each other, and thus the module can be made.

In addition, a plurality of ribs may be further formed on the upper plate to prevent strength and bending or twisting.

At this time, the ribs are formed concentrated on the main surface of the cover protrusion, but may be formed in any one of a plurality of circular, radial, and lattice-shaped concentric circles, or a mixture of two or more.

By combining the anti-vibration hole to the intermediate plate, an air layer is formed on the upper and lower portions of the intermediate plate, respectively, providing a noise-blocking effect by the second air layer.

In addition, the vibration load of the weight is absorbed and attenuated by the vibration isolator, but the intermediate plate coupled in the middle of the vibration isolator retransmits part of the vibration load to the vibration isolator through the top plate or is distributed to other vibration isolators, so that the transmission vibration absorption and wider Vibration noise can be reduced through vibration absorption in the range.

In addition, by forming the diameter of the lower part of the anti-vibration hole similar to the diameter of the intermediate plate coupling hole, the anti-vibration hole is quickly mounted on the intermediate plate, and the lowered coupling force between the vibration isolator and the intermediate plate is a coupling means that integrally couples the intermediate plate and the upper plate Preserved to enable rapid assembly.

1 is a cross-sectional view showing a floor structure for preventing interlayer noise according to a preferred embodiment of the present invention, and FIG. 2A is a cross-sectional view showing a vibration isolator having a stepped step according to the present invention.

As referenced, the floor structure 10 for preventing interlayer noise according to the present invention includes an intermediate plate 20, a vibration isolator 30 coupled to the intermediate plate, and a vibration isolator 30 coupled to the intermediate plate. It is provided in a structure including an upper plate 40.

The intermediate plate 20 is a plate material standardized to a certain size, and is made of ABS resin, which is a solid hard material, and a plurality of coupling holes 21 are formed at regular intervals inside.

The intermediate plate 20 is formed to have the same size as the upper plate, and if necessary, a plurality of coupling holes 21 may be formed so that the plurality of vibration isolators 30 are coupled at equal intervals. The intermediate plate 20 may be arranged to be arranged over the entire floor to be installed by being continuously arranged on the side, and at this time, the interval between the adjacent intermediate plates may be configured to be equally disposed between the vibration isolators inside the intermediate plate. have.

In addition, the intermediate plate 20 provides a double floating floor structure in which an air layer, which is a space on the side of a vibration isolator formed by a vibration isolator to be described later, is divided into an upper air layer 60 and a lower air layer 70. In this double-floating floor structure, noise generated from the upper layer passes through different media when it passes through the upper air layer, the middle plate, and the lower air layer sequentially and passes through different media, so the noise is partially reflected at the media boundary and the noise is transmitted to the lower layer. Can be minimized.

The vibration isolator 30 is molded from a spherical rubber having an elastic material, and is typically a vibration isolator.

The anti-vibration sphere 30 can be divided into an upper hemisphere 31 and a lower hemisphere 32 based on a horizontal plane passing through the center, and the diameter of the upper hemisphere is larger than the diameter of the lower hemisphere, so that the step 33 between the upper and lower hemispheres ) Is formed.

Preferably, the diameter of the lower hemisphere 32 is formed to be equal to or similar to the diameter of the coupling hole 21 of the intermediate plate to be easily inserted into the coupling hole, and the diameter of the upper hemisphere 31 is the coupling hole of the intermediate plate. It can be formed larger than the diameter so that it can be jammed.

For example, if the diameter of the lower hemisphere 32 is formed to be 0.5~3mm larger than the diameter of the coupling hole 21, it is possible to mount the anti-vibration hole in the coupling hole without applying a large force, while a certain amount of jamming prevents it from being easily removed. can do.

In addition, if the diameter of the lower hemisphere 32 is the same as or smaller than the coupling hole 21, it may be easily mounted in the coupling hole, but there is a disadvantage in that the coupling force is poor. However, this disadvantage can also be fixed by the coupling means 50 to be described later, it is possible to solve the problem caused by the lowering of the coupling force. However, in the assembling process, the vibration isolating hole can be easily removed from the intermediate plate until the vibration isolating hole is seated in the coupling hole of the intermediate plate and the upper plate is installed and then fixed by a coupling means, so it is troublesome to handle or store. There is this.

In addition, the diameter of the upper hemisphere 31 is larger than the coupling hole of the intermediate plate 20, so when the lower hemisphere inserts the coupling hole, the stepped portion 33, which is the boundary between the lower hemisphere and the upper hemisphere, is jammed. It can be settled or bonded. The diameter of the upper hemisphere may be formed in various sizes to form a step so that the upper part of the coupling hole of the intermediate plate is jammed, but preferably, it is formed with a diameter larger than the diameter of the coupling hole by 10% so as to reduce the manufacturing cost. This is what makes it happen.

In addition, as shown in FIG. 2B, a fitting groove 34 may be further formed in an annular shape along a portion in which the stepped portion 33 is formed in the lower hemisphere 32 of the vibration isolator.

The fitting groove 34 is formed to be a certain size smaller than the diameter of the lower hemisphere 32 of the anti-vibration sphere, but has the same or similar size as the coupling hole 21 of the intermediate plate. Preferably, the fitting groove 34 is formed with the same diameter as the intermediate plate coupling hole 21, and the lower hemisphere 32 is formed with a diameter of 0.5 to 2 mm larger than the fitting groove 34 to form a vibration-proof hole in the middle plate 20. (30) When assembling, it is easily inserted by pressing with a slight force, and it is caught by the fitting groove on the contrary to prevent it from being easily removed.

The vibration isolator 30 as described above can be formed in various sizes according to the installation conditions. Depending on the size of the vibration isolator, the thickness of the floating floor in the space on the side of the vibration isolator can be adjusted, and the amount of noise transmitted to the lower floor can be minimized by increasing the absorption power for the vibration load through the vibration isolator.

Next, the upper plate 40 is made of ABS resin, which is a hard hard material, and is placed on the upper part of the anti-vibration sphere 30 coupled to the intermediate plate 20.

The bottom surface of the upper plate 40 has a cover protrusion 41 protruding downward, and the cover protrusion 41 is arranged at the same distance as the arrangement interval of the vibration isolator 30 or the coupling hole 21 of the intermediate plate. When formed and installed, the center of the cover protrusion 41, the vibration isolator 30, and the intermediate plate coupling hole 21 are arranged on the same vertical line.

The cover protrusion 41 formed on the upper plate 40 may have a dome-shaped support hemisphere groove 411 formed on a bottom surface corresponding to the upper curved surface of the vibration isolator. The support hemisphere groove 411 is a structure that increases the contact area between the upper plate and the upper surface of the vibration isolator to concentrate the vibration load transmitted to the upper plate to the cover protrusion and quickly transmits the vibration load to the vibration isolator. In particular, since contact is made through a curved surface rather than a horizontal surface of the contact area, the vibration load acting in the horizontal direction as well as the vertical direction of the generated vibration load is transmitted to the vibration isolator and absorbed and attenuated to minimize the transmission of vibration to the lower layer. can do.

The material of the upper plate and the middle plate has been described as preferably using ABS resin, but it is not limited thereto, and substitutes for various materials of hard hard material fall within the scope of the present invention.

3A and 3B, the floor structure for preventing interlayer noise according to the present invention may further include a coupling means 50.

The coupling means 50 is a means for integrally coupling the upper plate 40 and the intermediate plate 20 to be spaced apart at a predetermined interval, and various known types such as fitting type, protrusion type, clip type, screw connection type, etc. By applying means, it can be configured to be integrally fastened while maintaining the gap between the intermediate plate and the upper plate.

These coupling means 50 may be formed in various ways as necessary, such as forming one at the edge of the floor structure material of the present invention, or forming one or a plurality at a portion adjacent to the vibration isolator, and preferably, the vibration isolator By forming at least one in the vicinity where 30 is placed, the gap between the upper plate and the middle plate in the part where the vibration isolator is placed is kept constant.

The coupling means 50 can be applied in a variety of known forms, preferably, as shown in Figure 3b, the arm coupling rod 51 having a locking groove 501 formed at an end thereof, and a locking protrusion 502 corresponding to the locking groove ) Is formed in a pair of male coupling bands 52 formed at the ends to be fastened.

That is, the arm coupling band 51 or the male coupling band 52 are formed at positions corresponding to each other on the opposite sides of the intermediate plate 20 and the upper plate 40 to be fastened. As shown, an arm coupling band 51 is formed on the upper surface of the intermediate plate 20, and a male coupling band 52 is formed on the bottom surface of the upper plate 40 to be combined. Can be formed to allow bonding to occur.

In addition, in the drawing, the intermediate plate 20 or the upper plate 40 is shown in a form in which a predetermined length protrudes from the opposite surface and then a locking groove 501 or a locking protrusion 502 is formed. Various changes can be made, such as forming a locking groove or a locking protrusion on the upper plate surface, extending and protruding long from the opposite surface, and then forming a corresponding locking protrusion or locking groove to be coupled.

In addition, the extended portion may be formed into a truncated cone or a polygonal truncated cone in addition to the cylindrical shape, so that stable coupling can be achieved.

In addition, the arm coupling band and the male coupling stand are illustrated in a form in which a locking step is formed inside or outside, but as shown in FIG. 3C, only a groove and a protrusion are formed without a locking step, and the fitting can be made by adjusting the dimensions. .

As shown in Fig. 3d, the coupling means 50 of the present invention has a locking hole 53 formed in the intermediate plate 20, and a locking protrusion 502 formed at the lower end of the upper plate 40. ) Can be configured by.

The locking protrusion 502 of the locking bar 54 is a locking hole 53 of the intermediate plate to be locked to the bottom of the intermediate plate, and can be moved in the direction of narrowing the gap between the upper plate and the intermediate plate. However, since the movement is limited by the anti-vibration device 30, a constant interval can be maintained at all times. In addition, the structure can be adjusted to maintain the same distance as the upper hemisphere of the anti-vibration sphere as the engaging member 54 is inserted into the locking hole 53 by the amount of deformation when the upper hemisphere of the anti-vibration sphere is pressed by pressure. I can do it.

In addition, the locking protrusion 54 may form a groove vertically at the center of the end where the locking protrusion 502 is formed so that the gap between the locking protrusions when the intermediate plate locking hole is inserted may be temporarily narrowed.

As shown in Figure 3e, the coupling means of the present invention is a partial perspective view showing that a plurality of clip portions are formed on the intermediate plate and the clip portion at a required position is vertically used.

As mentioned, a plurality of clip portions are formed on the intermediate plate. The clip part may be formed in a shape in advance during the injection process so that it can be easily installed vertically during use to enable use. In other words, three sides along the edge of the clip part on the intermediate plate are separated by forming a through hole along the cutting line, or a thin thickness is formed so that it can be easily cut, and the other side is formed to have a thin thickness so that it can be easily folded. It can be formed by

In addition, when the clip part is vertically upright, a protrusion is formed on the outermost part to be engaged with the upper plate, which is an opposite member, so as to be integrally coupled. For example, by forming a groove in the lower surface of the upper plate into which the projection of the clip part is inserted, or by forming a through hole in the upper plate so that the protruding part of the clip part is inserted through the upper plate and is jammed to the upper surface of the upper plate, etc. It may be provided in a coupling structure.

Although the clip part is shown to be formed on the middle plate, it may be provided in a structure in which the clip part is formed on the upper plate so that the middle plate is caught. In addition, although not shown, the clip portion may be configured as a separate clip, and the intermediate plate and the upper plate may be provided with a structure in which a through hole or a locking groove to which the clips are respectively coupled are formed.

When the coupling means 50 is provided in this way, since the upper hemisphere 31 of the vibration isolator can be fixed between the intermediate plate 20 and the upper plate 40, the intermediate plate 20 and the vibration isolator 30 and the upper plate Modularization by combining 40 can be achieved. That is, since it can be assembled and prepared in advance, it can be quickly installed on site, and construction time can be shortened by installing the floor structure.

As shown in FIGS. 4A to 4C, the upper plate 40 may further include a rib 42 in order to prevent strength and bend or twist.

The rib 42 is formed around the cover protrusion 41 in which the vibration load is concentrated from the top, and can be formed in a plurality of circles (Fig. 4a) or radial (Fig. 4b) having a concentric circle centered on the cover protrusion. Can be, it can be formed in a lattice shape (Fig. 4c) regardless of the cover protrusion. At this time, the strength of a specific portion may be improved by adjusting the spacing of the grid. In addition, ribs may be formed in various shapes to reinforce strength, such as being provided in a mixture of two or more of the circular radial grid types.

In addition, an upper plate formed of a styrofoam material or other various materials is further placed on the upper portion of the upper plate to further reduce interlayer noise.

The floor structure 10 for preventing interlayer noise of the present invention configured as described above,

The upper hemisphere 31 and the lower hemisphere 32 of the anti-vibration sphere 30 can be easily coupled to the intermediate plate 20 by different diameters, and the cover protrusion 41 formed on the bottom surface of the upper plate 40 is supported. The hemispherical groove 411 is formed to contact the upper part of the spherical vibration isolator 30 in a surface to facilitate the transmission of the vibration load generated from the upper part.

In particular, since the cover protrusion 41 surrounds a part of the upper part of the vibration isolator 30, vertical vibration as well as horizontal vibration is transmitted to the vibration isolator for absorption, thereby enabling effective vibration absorption, and the air layer on the side of the vibration isolating port is also multi-stage. By forming, it can increase the blocking effect of interlayer noise rather than a single layer.

In addition, the vibration load transmitted to the vibration isolator 30 through the cover protrusion 41 of the upper plate 40 is partially transferred to the intermediate plate 20 by the stepped portions 33 of the upper and lower hemispheres of the vibration isolator. The plate may be retransmitted to the upper plate 40 through the coupling means 50, and the upper plate may transmit the retransmitted vibration load back to the vibration isolator 30 so that vibration absorption is achieved. That is, most of the vibration load generated once is first absorbed by the vibration isolator 30, and the vibration load transmitted to some intermediate plate 20 is the intermediate plate 20 and the coupling means 50 and the upper plate 40 ) To be circulated through and re-delivered to the vibration isolator 30 so that secondary absorption can be made in the vibration isolator. Therefore, it is possible to reduce the vibration absorption burden of the vibration isolator by distributing the vibration load generated once in the first and second order to absorb the vibration isolator 30, and the reduction of the vibration absorption load increases the vibration absorption rate of the vibration isolator. It can be further increased to increase the reduction rate of inter-floor noise.
