Description

Noise-proof device for preventing interfloor noise {Noise-proof device for preventing interfloor-noise}

The present invention relates to a dustproof apparatus for reducing the noise transfer between floors in buildings, such as apartments.

The noise between floors of the building is mainly due to the noise of the living. Such noise includes the dining table, the dragging of the chair, the running of children, the footsteps of adults, the bass of the television or the audio.

The living noise generated in the upper floor of the multi-storey building is transmitted to the lower floor through the composite floor such as the concrete floor separating the upper and lower floors.

Conventional multi-storey buildings fixed the flooring under the concrete mortar layer forming the basic skeleton to reduce the noise between floors, and finished by combining a ceiling board, such as gypsum board on the flooring. As a result, the space between the concrete mortar layer and the ceiling plate was formed to reduce the interlayer noise transmitted from the upper layer to the lower layer to some extent.

However, the beams connecting the concrete mortar layer and the ceiling plate provide a path for transmitting vibrations and noises up and down. In particular, while additional lighting fixtures, ventilation holes, etc. are installed on the ceiling plate, the load that the ceiling plate must support increases, and thus, the rigidity of each member that fixes the ceiling plate also increases the rigidity, which makes the structure more vulnerable in terms of vibration or noise transmission. have.

Another conventional vibration isolator has a complicated mechanical structure. This conventional technology is mainly presented as a rubber block body manufactured in a specific shape, aimed at reducing the transmission of vibration or noise by increasing the elastic force of the rubber. However, the rubber block body of various shapes according to the prior art has a disadvantage in that it is ineffective in blocking low frequency vibration in the low range, such as a dull impact sound. In addition, since the rigidity of the rubber block body is required to support the load of the lighting fixtures, etc. installed on the ceiling plate, the rigidity of the material must be increased accordingly, and thus has a structure that is vulnerable to blocking transmission of vibration or noise.

The anti-vibration device according to the prior art has a structure for increasing the height of the anti-vibration device for sufficient stiffness and vibration blocking, which is not appropriate because it results in reducing the ceiling height of the room.

Patent Registration Publication No. 0928720 (Nov.19, 2009) Utility Model Publication No. 20-1996-00030720 (1996.10.22)

The present invention provides a dustproof apparatus that exhibits sufficient vibration and noise reduction effects without increasing the height of the dustproof apparatus. Specifically, it is possible to effectively reduce both low noise and high noise in the low frequency range, and to present a dustproof device with a minimum installation height.

The present invention is coupled to the main case part that can be fixed to the ceiling of the building, the ceiling member of the building in an embodiment, and is coupled to the auxiliary case portion and the main case portion and the auxiliary case portion located inside the main case portion, It proposes a dustproof device for interlayer noise reduction comprising an elastic support for elastically supporting the auxiliary case from the main case.

The elastic support part may be disposed in parallel on the same plane, and may include heterogeneous elastic parts that elastically connect the main case part and the auxiliary case part.

Specifically, at least one of the heterogeneous elastic parts may be a coil spring, an upper end of the coil spring may be connected to the auxiliary case, and a lower end of the coil spring may be connected to the main case.

In an additional configuration, a rubber plate may be interposed between the upper end of the coil spring and the auxiliary case part or between the lower end of the coil spring and the main case part.

As another example, the rubber block includes a plate in contact with one end of the coil spring, an extension part extending from the plate and inserted into the coil spring, and the expansion part is deformed while being coupled to the extension part of the rubber block. The coil spring may be coupled to the main case part or the auxiliary case part through an expansion member that adds to the coil spring.

In addition, the expansion portion may be a cylindrical columnar shape of the inner diameter gradually narrowed toward the plate, the expansion member may be inserted into the inner diameter of the cylindrical column to open the expansion portion.

In addition, at least one of the heterogeneous elastic parts may be a pair of magnets, one of the pair of magnets may be fixed to the main case part, and the remaining magnets maintain a repulsive relationship with a magnet attached to the main case part. While being able to be fixed to the auxiliary case.

Furthermore, the main case part may include at least one fixing bracket fixed to the ceiling of the building, and a connecting bracket coupled to a height of the fixing bracket. At this time, the fixing bracket and the connecting bracket is formed with the irregularities to be engaged with each other, the fixing bracket may be formed in the vertical hole in the vertical direction through which the bolt coupled to the connecting bracket passes.

According to the exemplary embodiment of the present invention, the heterogeneous elastic parts may be disposed on substantially one plane to increase the dustproofing effect while minimizing the height of the dustproofer. The dustproof apparatus of the present invention having a lower height than the dustproof apparatus according to the prior art has an effect of minimizing the reduction of the height of the room.

When the elastic support is made of a coil spring and a magnet, the magnet reinforces the elastic force of the coil spring to prevent the coil spring from being deformed beyond the elastic limit even when the load of the ceiling plate is greatly increased, and thus dustproofed by the coil spring. The effect can be sustained.

In addition, the rubber block or rubber plate is further coupled to the coil spring to effectively reduce vibration and noise in the low range. Furthermore, the expansion portion and the expansion member of the rubber block can be firmly fixed to the coil spring, improving the assembly of the dustproof device.

As the main case is separated into a fixing bracket and a connecting bracket, even if the ceiling is not flat, it is possible to easily install a flat ceiling plate. That is, the convenience of the construction work is greatly increased because it is performed in the prior art so that the height adjustment of the angle in the field is not necessary.

Dustproof device 100 according to an embodiment of the present invention is provided between the ceiling portion (L) of the building and the ceiling plate (M) which is spaced apart from the ceiling portion, connecting the ceiling portion (L) and the ceiling plate (M). will be.

Here, the ceiling (L) is a concrete mortar layer, or wood coupled to the concrete mortar layer. On the other hand, the ceiling plate (M) is a plate member widely used for interior finishing, for example, may be a gypsum board. However, the ceiling plate (M) may be a variety of finishing members, such as lumber (W), plywood in addition to the gypsum board. Therefore, the present invention should not be limitedly interpreted by the construction of the building ceiling part or ceiling plate.

In addition, in describing the present invention, for convenience of description, the main case part is fixed to the ceiling part, and the auxiliary case part is described as a component coupled to the ceiling plate, but the main case part is fixed to the ceiling plate and the auxiliary case part is a ceiling part. Can be used as fixed. In addition, the vibration isolator is applicable to not only the ceiling but also a normal vertical wall.

1 shows a dustproof device according to an embodiment of the present invention. 2 to 3 are separated views of main parts of the embodiment shown in FIG. 1.

The dustproof apparatus 100 according to the embodiment of the present invention includes a main case part 1, an auxiliary case part 2, and an elastic support part 3.

The main case part 1 is a member fixed to the ceiling of a building. The main case part 1 is formed of a bracket, and may be separated into a fixing bracket 11 and a connection bracket 12 as described below. Alternatively, the fixing bracket and the connecting bracket are integrally molded, so that the main case part may be formed of one integrated bracket.

The inside of the main case part 1 penetrates along the longitudinal direction. One surface of the main case part 1 is open along the longitudinal direction. Support pieces 121 are provided on both sides of one surface of the main case part 1. The support piece 121 faces the auxiliary case part 2 located inside the main case part 1. In the illustrated embodiment, the pair of support pieces 121 has a shape overlapping with both ends of the auxiliary case part 2 in some up and down directions.

On the other hand, the auxiliary case 2 is located inside the main case 1. Specifically, the auxiliary case part 2 is mounted on the support piece 121 of the main case part 1. At this time, both ends of the auxiliary case part are not in contact with the inner wall of the main case part.

In the drawing, the lower portion of the auxiliary case part 2 has a connection portion 21 to which the horn member W is connected. The lumber W coupled to the connecting portion 21 is further protruded downward from the lower end of the main case part 1 to be coupled to the ceiling plate M (see FIGS. 4 and 6 to 8). Although the ceiling plate M is shown to be connected to the auxiliary case part 2 through the shell member W in this embodiment, the connection part of the auxiliary case part is formed to protrude further below the lower end of the main case part, and this connection part It is also possible to omit the shell by directly joining the ceiling panels.

The elastic support 3 is a member that elastically supports the auxiliary case 2 with respect to the main case 1.

In the embodiment, the elastic support 3 is provided between the support piece 121 and the auxiliary case 2 of the main case 1. The elastic support part 3 spaces apart the auxiliary case part 2 from the support piece 121 of the main case part 1 and at the same time elastically supports the auxiliary case part 2 with respect to the vertical downward.

This elastic support 3 is composed of at least one elastic portion.

The elastic portion may be provided in plurality, wherein the elastic portion may be provided in different types. In the case where the elastic support portion is composed of a plurality of elastic portions, each elastic portion may be composed of two or more kinds selected from generally known elastic bodies such as a coil spring having elasticity, a shock absorber using a fluid such as compressed air, a magnet, a rubber block body, and the like. .

In the embodiment shown as an example, there are provided elastic portions composed of four coil springs 31 and two pairs of magnets 32.

Furthermore, the plurality of elastic portions are arranged in parallel on substantially the same plane. In the figure coil coils 31 and magnets 32 are arranged on a plane. Furthermore, each coil spring 31 is arranged symmetrically with respect to the connection portion 21. The symmetry of the left and right symmetry is to allow the load transmitted to the auxiliary case portion through the lumber to be equally supported left and right without biasing to either side.

Looking at the coil spring 31, which is one of the elastic parts in detail, the upper end of the coil spring 31 is connected to the auxiliary case 2, the lower end is connected to the main case (1).

The rigidity of the coil spring 31 can be increased to sufficiently withstand the load of the structure installed on the ceiling plate, including the ceiling plate (M). In this case, when the end portion of the coil spring 31 is directly connected to the main case part 1 and the auxiliary case part 2 by welding or the like, the vibration of the main case part 1 is perfectly supported by the coil spring 31. It is transmitted to the case part 2 and there exists a possibility that a dustproof effect may fall.

In order to solve this problem, a rubber plate 331 is provided between the upper end of the coil spring 31 and the auxiliary case 2 or between the lower end of the coil spring 31 and the main case 1. May be interposed. That is, the rubber plate is coupled to the upper end or the lower end of the coil spring, or both ends of the coil spring.

In this case, the coupling between the rubber plate and the coil spring and the coupling between the plate and the auxiliary case part or the main case part are made through a well-known coupling means such as bonding or bolting.

As a more effective means of coupling the coil spring 31, the present invention provides a rubber block 33 and an expansion member 34.

2 to 4, the rubber block 33 is coupled to one end of the coil spring 31. The rubber block 33 includes a plate 331 having a diameter equal to or larger than the outer diameter of the coil spring 31 and an extension 332 extending from the plate 331 and inserted into the coil spring 31. Include. The extension 332 has an outer diameter that is substantially the same size as the inner diameter of the coil spring 31.

The expansion member 34 is a member that expands the outer diameter of the expansion portion 332 while being coupled to the expansion portion 332. As the outer diameter of the expansion part 332 is increased by the expansion member 34, the expansion part 332 may firmly fix the coil spring 31.

Specifically, in FIG. 4, the expansion part 332 has a cylindrical pillar shape in which an inner diameter gradually narrows toward the plate 331. In addition, the expansion member 34 is in the shape of a truncated cone inserted into the inner diameter of the cylindrical pillar.

When the expansion member 34 moves toward the inside of the extension 332, that is, the plate 331, by the rotation of the screw 35, the expansion part 332 made of rubber material opens outwards and coil coil 31. ) Will be pressed. At this time, since the expansion part 332 is deformed and the coil spring 31 is penetrated, the coil spring 31 is firmly fixed to the rubber block 33.

In this way, the expansion portion capable of being wider than the inner diameter of the coil spring and the expansion member acting to open the expansion portion may be variously changed in addition to the illustrated configuration. Although not illustrated, the extension part may be formed of metal cut pieces that are radially inserted into the plate, and the expansion member may be a structure having various shapes that radially open the metal cut pieces while being moved toward the plate.

The rubber block 33 and the expansion member 34 is coupled to at least one of the upper end and the lower end of the coil spring 31, or may be applied to both ends as shown.

On the other hand, one of the elastic portion of the magnet 32 is provided in pairs.

The pair of magnets 32 are fixed to the main case part 1 and the auxiliary case part 2, respectively. In the present embodiment, the support piece 121 of the main case part 1 has a pair of biting pieces 122 having protrusions protruding from the ends thereof, so that the flat plate magnets can be bite fixed. In contrast, the magnet may be mounted to the main case part 1 by a general fixing means such as an adhesive. In addition, the fixing method of the magnet 32 to the auxiliary case part 2 may be the same as the method of fixing the magnet 32 to the main case part (1).

The magnets 32 mounted to the main case part 1 and the auxiliary case part 2 corresponding to each other are arranged to have the same polarity of the faces facing each other to form a repulsive relationship.

Meanwhile, in the illustrated embodiment, the main case part 1 includes a fixing bracket 11 and a connecting bracket 12. The fixing bracket 11 is fixed to the ceiling (L) of the building is provided with a pair symmetrically to each other. The connecting bracket 12 is coupled to the elastic support 3 and the auxiliary case 2 is located inside, and is coupled to adjust the height relative to the fixed bracket (11).

In the figure is shown that the fixing bracket 11 is provided on the left and right of the connecting bracket 12, respectively. The number of such fixing brackets may vary.

In the illustrated embodiment, the fixing bracket 11 and the connecting bracket 12 are formed with a plurality of recesses and protrusions 111 engaged with each other.

The uneven parts 111 are formed long in the front and rear directions of the fixing bracket 11 and the connecting bracket 12. Accordingly, the connecting bracket 12 is slidably moved back and forth to separate the fixed bracket 11 fixed to the ceiling of the building, and then the coupling bracket 12 is slidably coupled to the fixed bracket 11 according to the required height.

Furthermore, in order to more securely fix the fixing bracket 11 and the connecting bracket 12, the fixing bracket 11 is formed with a long hole 112 in the vertical direction through which the bolt 113 coupled to the connecting bracket 12 passes have. The bolt 113 is fastened to the long hole 112 of the fixing bracket 11 and the hole of the connecting bracket 12 and is firmly connected to the fixing bracket 11 and the connecting bracket 12.

Height adjustment of the connecting bracket coupled to the fixed bracket can be made in a variety of ways other than the coupling by the above-mentioned bumps and bolts. For example, a protrusion and a sliding groove are formed on the fixing bracket and the connecting bracket so that the connecting bracket can slide up and down with respect to the fixing bracket, and a plurality of holes in the up and down direction are formed in the fixing bracket so that both can be fixed at an appropriate height. The height of the connecting bracket relative to the fixed bracket may be adjusted by providing a pin passing through one of the holes and the hole of the connecting bracket.

Hereinafter, with reference to the accompanying drawings will be described the operation of the dustproof device for reducing the noise between the floor according to an embodiment of the present invention.

Referring to FIGS. 1 and 4, the main case part 1 connected to the ceiling part L of the building and the auxiliary case part 2 connected to the ceiling plate M do not directly contact each other, but instead contact the elastic support part 3. It is connected in a state in which a relatively elastic movement is possible.

4 is an initial state in which the coil spring 31 is pressed by the weight of the auxiliary case part 2 in a state that the ceiling plate or the like is not coupled to the auxiliary case part 2. On the other hand, Figure 6 is that the auxiliary plate (2) is connected to the ceiling plate (M), the load of these acts in the direction to press the coil spring 31, the coil spring 31 is pressed.

When the lighting fixtures suspended on the ceiling plate (M) is replaced with a heavy one or a ceiling fan or the like is newly installed, the load transmitted to the auxiliary case increases, so that the coil spring may be further compressed.

When the load by the ceiling plate or the like increases to an extent that exceeds the elastic modulus of the coil spring 31, the coil spring 31 loses its function and the dustproof effect can be rapidly reduced. In this case, the repulsive force obtained from the pair of magnets 32 corresponding to each other complements the elastic force of the coil spring, thereby preventing the auxiliary case part 2 and the main case part 1 from being too close to each other. That is, when a load greater than the elastic force of the coil spring 31 acts and the auxiliary case 2 descends, as shown in FIG. 7, the magnet 32 and the main case part fixed to the auxiliary case part 2 ( The magnets 32 fixed to 1) are close to each other and the repulsive force is greatly applied.

The main case part 1 and the auxiliary case part 2 can be kept spaced apart from each other by the increased repulsive force, and the dust is prevented by the coil spring 31 by preventing the coil spring 31 from being completely compressed. The effect can be sustained.

This advantage is to maintain the existing dust-proof effect even when replacing the luminaire hanging from the ceiling of the room with a heavier product than the existing luminaire after the completion of the interior construction, or when a wall-mounted fan is newly installed on the wall finish. It is the main one.

In addition, by providing different types of elastic portion has the advantage of bringing an effective dust-proof effect in a variety of bands.

On the other hand, it is possible to minimize the height increase of the vibration isolator 100 by disposing different kinds of elastic parts, such as the coil spring 31 and the magnet 32 on substantially the same plane.

In the conventional anti-vibration apparatus, a structure for increasing the vertical height of the elastic part is adopted to ensure an appropriate anti-vibration effect. However, the present invention arranges the elastic parts on a plane to shorten the vertical length of the anti-vibration device 100. Can be reduced. This reduces the height of the room and minimizes the indoor area sensation due to the increased wall thickness.

Furthermore, the plate 331 or the rubber block 33 made of an elastic material is coupled to one or both ends of the coil spring 31 so that the coil spring 31 having a large rigidity is provided in the auxiliary case part 2 or the main case part 1. It is configured not to directly contact. That is, the vibration or noise transmitted from the ceiling of the upper layer is further reduced through the plate or the rubber block.

Furthermore, by the expansion part 332 and the expansion member 34 of the rubber block 33 it is possible to firmly fix the coil spring 31 and to eliminate a complicated configuration such as a separate spring guide or spring fixing means. do.

Referring to FIGS. 4 and 9, the main case part 1 includes the fixing bracket 11 and the connecting bracket 12, so that the ceiling plate M may be horizontally mounted even when the ceiling part L is bent. .

Even if the ceiling portion (L) of the building is not horizontal, it is possible to obtain a horizontal ceiling plate (M) by appropriately adjusting the height of the connecting bracket 12 fixed to each fixing bracket (11).

In the prior art, the worker needed to separately adjust the height of the lumber at the construction site, but when the present invention is applied, there is a convenience to reduce the labor of such a site.
