Description

Interlayer noise abatement system {Interlayer noise abatement system}

The present invention relates to an inter-floor noise reduction system.

Buildings such as multi-unit dwellings and apartments share floors and walls. In particular, between floors of a building is partitioned by slabs, where a floor structure of an upper floor and a ceiling structure of a lower floor may be located on the slab. Recently, as buildings become high-rise, floor slabs are used as lightweight materials or thin floor slabs are constructed to reduce weight. In this way, when the slabs dividing the floors of the building are thinned, there is a problem in that the impact sound generated in the upper floors is easily transmitted to the lower floors.

In order to solve this problem, a structure for blocking impact sound from being transmitted is installed between the slab and the floor finishing material constituting the floor. Such a structure is disclosed in Korean Patent Registration No. 10-1245376, Korean Patent Publication No. 10-2009-0078228, and Korean Patent Registration No. 10-0653596.

However, in the conventional technologies, if the structure for absorbing shock is thickened, the floor finishing structure including the slab becomes thick, so that it is impossible to secure the floor height of the indoor space.

A fourth anti-vibration layer including a fourth anti-vibration hole and a fourth anti-vibration plate may be further formed on the second anti-vibration layer or the third anti-vibration layer. And the fourth ball rest can be supported on the edge of the fourth body plate.

According to another feature of the present invention, the present invention includes at least two anti-vibration layers sequentially stacked on a slab including an anti-vibration ball made of an elastic material that absorbs shock and an anti-vibration plate seated on the anti-vibration ball, and the at least two anti-vibration layers It may include a mortar layer formed on the above anti-vibration layer and having pipes buried therein, and a floor finishing material installed on the mortar layer, and the anti-vibration plate constituting the anti-vibration layer has an upper portion that is open to the top and protrudes downward. A concave portion may be formed, and the cross-sectional area of the upper concave portion may gradually decrease toward the upper dustproof layer.

The anti-vibration plates may be installed with a predetermined gap between them and a portion supported by each anti-vibration ball.

The anti-vibration plate may have an upper concave portion that is recessed from the upper surface of the body plate and protrudes from the lower surface of the body plate, so that the upper concave portion of the relatively upper anti-vibration plate is seated in the upper concave portion of the lower anti-vibration plate. can

The top anti-vibration layer includes an anti-vibration plate and a vibration-isolation plate composed of a plate-shaped body plate whose edges are supported by the anti-vibration sphere, and The anti-vibration ball constituting the anti-vibration layer may be positioned in an upper concave portion of the anti-vibration plate constituting the relatively lower anti-vibration layer.

The inter-floor noise reduction system according to the present invention may have at least one or more of the following effects.

In the present invention, since the first anti-vibration layer and the second anti-vibration layer overlapping each other in the height direction are stacked on the upper surface of the slab of the building to absorb the impact applied to the floor of the upper floor, there is an effect of relatively reducing inter-floor noise.

In the present invention, since the first anti-vibration layer and the second anti-vibration layer overlapping in the height direction are installed on the upper surface of the slab, the floor structure installed on the upper surface of the slab can be made to have a relatively low height. Therefore, it is possible to minimize inter-floor noise while maintaining the floor height of each floor at a certain value or more by lowering the floor structure installed on the upper surface of the slab while better absorbing the impact applied to the floor of the upper floor.

In the present invention, the first anti-vibration plate constituting the first anti-vibration layer and the second anti-vibration plate constituting the second anti-vibration layer overlap in the height direction so that even if the first anti-vibration layer and the second anti-vibration layer are sequentially stacked, the height of the entire anti-vibration layer is can be relatively low. In addition to this, the first anti-vibration ball installed between the slab and the first anti-vibration plate and the second anti-vibration ball installed between the first anti-vibration plate and the second anti-vibration plate are substantially stacked to absorb shock, thereby absorbing the impact. It is possible to absorb more shock while relatively lowering the noise between floors, thereby reducing noise between floors more effectively.

In addition, the first anti-vibration plate and the surface of the slab do not directly contact each other, and a first anti-vibration ball is placed therebetween, and a second anti-vibration ball is placed between the first anti-vibration plate and the second anti-vibration plate. Since the first anti-vibration plate can act as a kind of spring, the first anti-vibration plate can also act as a shock absorber. Therefore, reduction of inter-floor noise can be achieved more effectively.

Meanwhile, second upper concave portions that open upward are formed on the surface of the second anti-vibration plate. Therefore, the height of the mortar layer formed on the second anti-vibration plate is relatively high where the second upper concave portion is located, and the height of the mortar layer is relatively low at the position of the second body plate of the second anti-vibration plate. can In this way, there is an effect of preventing resonance by making the thickness of the mortar layer non-uniform.

In the present invention, at least two or more anti-vibration layers composed of an anti-vibration ball and an anti-vibration plate may be laminated. Therefore, if there is no limit to the thickness of the floor structure formed on the slab, it is possible to completely absorb and remove the impact applied to the floor of the upper layer by forming a necessary anti-vibration layer.

Hereinafter, some embodiments of the present invention will be described in detail through exemplary drawings. In adding reference numerals to the components of each drawing, it should be noted that the same components have the same numerals as much as possible even if they are displayed on different drawings. In addition, in describing an embodiment of the present invention, if it is determined that a detailed description of a related known configuration or function hinders understanding of the embodiment of the present invention, the detailed description will be omitted.

Also, terms such as first, second, A, B, (a), and (b) may be used in describing components of an embodiment of the present invention. These terms are only used to distinguish the component from other components, and the nature, order, or order of the corresponding component is not limited by the term. When an element is described as being “connected,” “coupled to,” or “connected” to another element, that element may be directly connected or connected to the other element, but there may be another element between the elements. It should be understood that may be "connected", "coupled" or "connected".

As shown in the drawings, the slab 10 partitioning between floors of a building may be formed to have a predetermined thickness. An upper floor structure may be installed on the bottom of the slab 10 . A lower ceiling may be installed on the lower surface of the slab 10 .

The present invention is to provide a system that is formed on the bottom of the slab 10 to absorb impact generated on the floor of the upper floor and block inter-floor noise from being transmitted to the lower floor.

A first anti-vibration layer 20 and a second anti-vibration layer 30 may be formed by being stacked on the bottom of the slab 10 . In the illustrated embodiment, the anti-vibration layers 20 and 30 are composed of two, but the anti-vibration layers 20 and 30 may be two or more.

The first anti-vibration layer 20 and the second anti-vibration layer 30 may overlap a predetermined section in the height direction. In other words, the convex part protruding downward of the second anti-vibration layer 30 is located on the concave part open to the upper part of the first anti-vibration layer 20, and the first anti-vibration layer 20 and the second anti-vibration layer 30 ) may overlap a predetermined section in the height direction. Therefore, although the first anti-vibration layer 20 and the second anti-vibration layer 30 are stacked, the height of the entire anti-vibration layer 20 and 30 is equal to that of the first anti-vibration layer 20 and the second anti-vibration layer 30, respectively. can be lower than the sum of their heights.

The first anti-vibration layer 20 may include a first anti-vibration ball 21 and a first anti-vibration plate 22 .

A first ball bearing 21 may be positioned on the slab 10 . The first vibration ball 21 has a predetermined elasticity and can absorb impact. The first vibration release ball 21 may be made of, for example, a rubber material having good elasticity. The first square sphere 21 has a hexahedral shape in the illustrated embodiment. However, the first square ball 21 may have various shapes other than a hexahedron. For example, a part of the vertical section in the height direction of the first control ball 21 may be trapezoidal.

A plurality of coupling protrusions 21' may be provided on the upper surface of the first vibration ball 21. The coupling protrusion 21' may protrude upright on the upper surface in a cylindrical shape. A plurality of coupling protrusions 21' may be present on the upper surface. The coupling protrusions 21' may be positioned adjacent to the upper surface edge of the first dust-proof ball 21, respectively. The coupling protrusion 21' is for coupling with the first anti-vibration plate 22 to be described below. However, the engaging protrusions 21' do not necessarily exist. If there is another structure that prevents the first anti-vibration ball 21 from moving relative to the first anti-vibration plate 22, it does not matter if the coupling protrusion 21' is absent. As another example of such a structure, there is a partition wall 28 to be described below.

A plurality of the first dust-proof spheres 21 may be installed at predetermined intervals in all directions. This can be seen in FIG. 2 or FIG. 3 . A first anti-vibration plate 22 may be installed on the first anti-vibration sphere 21 . The first anti-vibration sphere 21 may be positioned to support the center and the edge of the first anti-vibration plate 22 . This is to enable the first vibration isolation plate 22 to be most stably supported by the first vibration isolation sphere 21 .

As shown in FIG. 4 , the first anti-vibration plate 22 may have a concavo-convex structure. The first body plate 23, which is the uppermost part of the first anti-vibration plate 22, may have a plate shape having a predetermined shape and area. In the illustrated embodiment, the first body plate portion 23 has a rectangular plate shape. The first body plate portion 23 may have a coupling hole 23' into which the coupling protrusion 21' of the first vibration ball 21 is coupled. The coupling hole 23' is a through hole in this embodiment, but may be a groove shape otherwise.

A first upper concave portion 24 may be formed lower than the first body plate portion 23 in the first anti-vibration plate 22 . A bottom surface of the first anti-vibration plate 22 corresponding to the first upper concave portion 24 may be a first lower convex portion 24'. The first lower convex portion 24' may convexly protrude from the lower surface of the first body plate portion 23. The first upper concave portion 24 may be formed in plurality. In this embodiment, four first upper concave portions 24 are formed. However, the number of the first upper concave portions 24 may be varied.

A first lower concave portion 26 may be formed on a bottom surface of the first anti-vibration plate 22 between the first upper concave portions 24 . A part of the first dust-proof ball 21 may be located in the first lower concave portion 26 . The coupling hole 23' into which the coupling protrusion 21' of the first relief ball 21 is inserted may be formed at a position corresponding to the first lower concave portion 26.

The depth of the first lower concave portion 26, in other words, the degree of protrusion of the first lower convex portion 24' is smaller than the height of the first relief ball 21. Therefore, when the first ball bearing 21 is located in the first lower concave portion 26, the first lower convex portion 24' will have a predetermined gap between the upper surface and the slab 10. can The gap may have a value greater than a length through which the first ball valve 21 is compressed. This is to prevent the first vibration isolation plate 22 from directly contacting the upper surface of the slab 10 even when the first vibration isolation sphere 21 is compressed.

When viewed in plan view, the first anti-vibration plate 22 has a rectangular shape in the drawing, but this is not necessarily the case. When the first anti-vibration plate 22 is placed on the bottom of the slab 10, any shape can be installed without gaps between adjacent first anti-vibration plates 22. For example, it can be a triangle, a pentagon, etc. In addition, the planar shape of the first anti-vibration plate 22 may be made in such a way that portions of adjacent ones of the first body plate 23 overlap each other at the edge of the first anti-vibration plate 22 .

A partition wall 28 may be provided at the bottom of the first upper concave portion 24 . The partition wall 28 may partition the resting ball seat space 29 in which the second ball bearing 31, which will be described below, is located, from the surroundings. The second anti-vibration ball 31 is positioned in the anti-vibration ball mounting space 29 formed in the partition wall 28 so that the first anti-vibration plate 22 and the second anti-vibration ball 31 are coupled so as not to move relative to each other. . The partition wall 28 is designed to form a quadrangle in this embodiment. The shape of the partition wall 28 may be determined according to the shape of the second ball bearing 31 . The partition wall 28 may have a predetermined inclination. The partition wall 28 may be inclined so that the distance between the partition walls 28 increases as the upper end of the partition wall 28 increases. This inclination can make it possible to easily locate the second ball bearing 31 to be described below in the ball bearing seating space 29 .

The second anti-vibration layer 30 may include a second anti-vibration ball 31 and a second anti-vibration plate 32 .

The second dust ball 31 may have the same size and shape as the first dust ball 21 . The second vibration ball 31 also has a predetermined elasticity to absorb impact. The second vibration isolation sphere 31 may be made of, for example, a rubber material having good elasticity. The second square sphere 31 has a hexahedral shape in the illustrated embodiment. However, the shape of the second ball-square 31 may also have various shapes like the first ball-square 21 .

A plurality of coupling protrusions 31' may be provided on the upper surface of the second vibration ball 31. The coupling protrusion 31' may protrude upright on the upper surface in a cylindrical shape. A plurality of coupling protrusions 31' may be present on the upper surface. The coupling protrusions 31 ′ may be located at positions adjacent to corners of the upper surface of the second vibration isolation sphere 31 . The coupling protrusion 31' is for coupling with the second anti-vibration plate 32 to be described below. However, the coupling protrusion 31' does not necessarily exist. If there is another structure that prevents the second anti-vibration ball 31 from moving relative to the second anti-vibration plate 32, it does not matter if the coupling protrusion 31' is absent. Another example of such a structure is the partition wall 28 . If a structure such as the partition wall 28 is formed on the bottom surface of the second anti-vibration plate 32, the coupling protrusion 31' may not exist.

The second anti-vibration ball 31 is seated in the partition wall 28 of the first anti-vibration plate 22, and the second anti-vibration plate 32 can be supported by the second anti-vibration ball 31. there is. The second anti-vibration sphere 31 may be positioned to support the center and the edge of the second anti-vibration plate 32 . This is to enable the second vibration isolation plate 32 to be most stably supported by the second vibration isolation sphere 31 .

As shown in FIG. 6 , the second anti-vibration plate 32 may have a concavo-convex structure. The second body plate 33, which is the uppermost part of the second anti-vibration plate 32, may have a plate shape having a predetermined shape and area. In the illustrated embodiment, the second body plate portion 33 has a rectangular plate shape. The second body plate portion 33 may have a coupling hole 33' into which the coupling protrusion 31' of the second ball bearing 31 is coupled. The coupling hole 33' is a through hole in this embodiment, but may be a groove shape otherwise.

A second upper concave portion 34 may be formed lower than the second body plate portion 33 in the second anti-vibration plate 32 . A bottom surface of the second anti-vibration plate 32 corresponding to the second upper concave portion 34 may be a second lower convex portion 34'. The second lower convex portion 34' may convexly protrude from the bottom surface of the second body plate portion 33. The second upper concave portion 34 may be formed in plurality. In this embodiment, 16 second upper concave portions 34 are formed. However, the number of the second upper concave portions 34 may be varied.

Although not shown in the drawings, a partition wall such as the partition wall 28 may be formed at the bottom of the second upper concave portion 34 . The partition wall formed in the second upper concave portion 34 may partition a space in which a dust-proof ball constituting an additional anti-vibration layer formed on the upper portion of the second anti-vibration layer 30 is seated.

A second lower concave portion 36 may be formed on the bottom surface of the second anti-vibration plate 32 between the second upper concave portion 34 . A part of the second dust proof ball 31 may be located in the second lower concave portion 36 . The coupling hole 33' into which the coupling protrusion 31' of the second ball bearing 31 is inserted may be formed at a position corresponding to the second lower concave portion 36.

The depth of the second lower concave portion 36, in other words, the degree of protrusion of the second lower convex portion 34' is smaller than the height of the second relief ball 31. Therefore, when the second anti-vibration sphere 31 is located in the second lower concave portion 36, the second lower convex portion 34' is the first upper concave portion 34 of the first anti-vibration plate 22. ) may have a predetermined gap between the bottom and the bottom. The gap may have a greater value than a length through which the second dust ball 31 is compressed. This is to prevent the second anti-vibration plate 32 from directly contacting the first anti-vibration plate 22 even when the second anti-vibration sphere 31 is compressed.

When viewed in plan view, the second anti-vibration plate 32 has a rectangular shape in the drawing, but this is not necessarily the case. When the second anti-vibration plate 32 is placed on the first anti-vibration plate 22, any shape can be installed without gaps between adjacent second anti-vibration plates 32. For example, it can be a triangle, a pentagon, etc. In addition, the planar shape of the second anti-vibration plate 32 may be made in such a way that portions of adjacent second body plate parts 33 overlap each other at the edge of the second anti-vibration plate 32 .

The size of the second anti-vibration plate 32 may be the same as that of the first anti-vibration plate 22 . However, the shape and size of the second anti-vibration plate 32 may be different from that of the first anti-vibration plate 22 . For example, the second anti-vibration plate 32 may be made by cutting the one of the illustrated embodiment in half.

And, when the second anti-vibration plate 32 is seated on the first anti-vibration plate 22, as shown in FIG. 8, it may be positioned over the plurality of first anti-vibration plates 22. In FIG. 8 , it can be seen that the second anti-vibration plate 32 is positioned over the three first anti-vibration plates 22 . In this way, the first anti-vibration plate 22 and the second anti-vibration plate 32 are coupled so that one second anti-vibration plate 32 is not seated on the first anti-vibration plate 22, and is offset from each other. One second anti-vibration plate 32 may be positioned over the first anti-vibration plate 22 . In this way, the reason why the first anti-vibration plate 22 and the second anti-vibration plate 32 are not overlapped is that the first anti-vibration ball 21 and the second anti-vibration ball 31 are the first anti-vibration plate ( 22) and the second anti-vibration plate 32, while supporting the edge and center, the first anti-vibration ball 21 and the second anti-vibration ball 31 are not at the same position in the height direction.

In order to have such a structure, the cross-sectional areas of the first upper concave portion 24 and the second upper concave portion 34 must be different. That is, the cross-sectional area of the second upper concave portion 34 in the relatively upper layer should be reduced. This is to ensure that the relatively upper second lower convex portion 34' can be seated in the relatively lower first upper concave portion 24.

In this embodiment, the number of second upper concave portions 34 formed on the second anti-vibration plate 32 corresponds to the square of the number of first upper concave portions 24 of the first anti-vibration plate 22. can For example, if the first upper concave portion 24 of the first anti-vibration plate 22 is two, four second upper concave portions 34 are formed, and the first upper concave portion 24 is four. Sixteen second upper concave portions 34 may be formed on the back surface.

Meanwhile, in FIGS. 9 and 10 , an embodiment in which three or more anti-vibration layers are disclosed in the present invention. In this embodiment, a third anti-vibration layer 130 and a fourth anti-vibration layer 140 are additionally formed on the first anti-vibration layer 20 and the second anti-vibration layer 30 of the above embodiment.

In FIGS. 9 and 10, it is shown that the anti-vibration layer is formed in a total of four layers, the first anti-vibration layer 20, the second anti-vibration layer 30, the third anti-vibration layer 130, and the fourth anti-vibration layer 140. there is. Here, since the structure of the first anti-vibration layer 20 and the second anti-vibration layer 30 has already been described in the above embodiment, description thereof will be omitted.

The third anti-vibration layer 130 may include a third anti-vibration ball 131 and a third anti-vibration plate 132 . The third dust ball 131 may be made of an elastic material. The third ball 131 has the same configuration as the first ball 21 or the second ball 31, such as having a coupling protrusion 131'. The third anti-vibration ball 131 may be located in any one of the second upper concave portions 34 of the second anti-vibration plate 32 .

A third anti-vibration plate 132 may be installed on the third anti-vibration sphere 131 . The third anti-vibration ball 131 may be positioned to support the center and the edge of the third anti-vibration plate 132 . This is to allow the third vibration isolation plate 132 to be most stably supported by the third vibration isolation sphere 131 .

The configuration of the third anti-vibration plate 132 is similar to that of the second anti-vibration plate 32 . The third anti-vibration plate 132 may form a third body plate 133 at an uppermost part. A coupling hole 133' to which the coupling protrusion 131' is coupled may be formed in the third body plate portion 133. A third upper concave portion 134 recessed into the third body plate portion 133 may be formed in the third anti-vibration plate 132 . The third upper concave portion 134 may be formed in multiple numbers, and in this embodiment, eight are formed. The opposite side corresponding to the third upper concave portion 134 may be the third lower convex portion 134'. A third lower concave portion 136 may be formed between the third lower convex portion 134' corresponding to the bottom surface of the third body plate portion 133. A third release ball 131 may be positioned on one side of the third lower concave portion 136 .

The fourth anti-vibration layer 140 may include a fourth anti-vibration ball 141 and a fourth anti-vibration plate 142 . The fourth dust ball 131 may be made of an elastic material. The fourth square ball 141 has the same configuration as the first to third square ball 21, 31, and 131, such as having a coupling protrusion 141'. The fourth anti-vibration ball 141 may be located in any one of the third upper concave portions 134 of the third anti-vibration plate 132 .

For reference, when the cross sectional area of the third upper concave portion 134 is equal to the cross sectional area of the anti-vibration sphere 141, the anti-vibration layer cannot be added using the anti-vibration plate having the upper concave portion. Of course, if the cross-sectional area of the anti-vibration sphere is the same as that of the upper concave portion having a smaller cross-sectional area than the cross-sectional area of the third upper concave portion 134, an additional anti-vibration layer is possible. In the case of using a true ball, an anti-vibration layer cannot be added.

A fourth anti-vibration plate 142 may be installed on the fourth anti-vibration sphere 141 . The fourth anti-vibration ball 141 may be positioned to support the center and the edge of the fourth anti-vibration plate 142 . This is to enable the fourth vibration isolation plate 142 to be most stably supported by the fourth vibration isolation sphere 141 .

The fourth anti-vibration plate 142 may have a flat plate shape. A fourth body plate 143 may be formed at the uppermost part of the fourth anti-vibration plate 142 . The fourth body plate portion 143 is a flat plate. A plurality of coupling holes 143' may be formed in the fourth body plate 143. The fourth anti-vibration plate 142 may be seated on the fourth anti-vibration sphere 141 to form the uppermost layer of the anti-vibration layer.

For reference, the number of anti-vibration layers can be varied to suit the construction site. For example, the anti-vibration layer may be formed in three layers using the first anti-vibration layer 20 , the second anti-vibration layer 30 , and the third anti-vibration layer 130 . The first anti-vibration layer 20, the second anti-vibration layer 30, the third anti-vibration layer 130, and the fourth anti-vibration layer 140 may be used to form four layers of anti-vibration layer. The first anti-vibration layer 20, the second anti-vibration layer 30, and the fourth anti-vibration layer 140 may have three anti-vibration layers. In addition, the first anti-vibration layer 20, the third anti-vibration layer 130, the first anti-vibration layer 20 and the fourth anti-vibration layer 140 may each have two layers. The second anti-vibration layer 30, the third anti-vibration layer 130, and the fourth anti-vibration layer 140 may be used to form three layers. The second anti-vibration layer 30 and the third anti-vibration layer 130, and the second anti-vibration layer 30 and the fourth anti-vibration layer 140 may each have two layers.

When the anti-vibration layer is formed in multiple layers with a plurality of combinations as described above, the cross-sectional area of the upper concave portion of the anti-vibration plate located at the lower portion should be relatively large. Of course, the fourth anti-vibration plate 142 must constitute the uppermost layer.

In addition, although not shown in the drawings, the first anti-vibration plate 22 and the second anti-vibration plate 32 adopt an upper concave portion in which the cross-sectional area decreases and the number increases as you go to the upper layer, so that the anti-vibration layer has three or more layers In order to form, the cross-sectional area of the first upper concave portion 24 of the first anti-vibration plate 22 may be relatively increased. This is because the anti-vibration layer can be formed in multiple layers only when the maximum number of anti-vibration plates having an upper concave portion that gradually decreases as the layer goes up is made. To this end, it is necessary to increase the absolute size of the first anti-vibration plate 22 compared to the illustrated embodiment.

Hereinafter, it will be described that the installation of the inter-floor noise reduction system according to the present invention having the above configuration and that noise reduction is achieved thereby.

A plurality of first vibration holes 21 may be installed on the upper surface of the slab 10 . Of course, the first anti-vibration ball 21 may be placed on the slab 10 in a state where the first anti-vibration ball 21 is coupled to the first anti-vibration plate 22 . That is, the first anti-vibration layer 20 is positioned on the slab 10 . When the first anti-vibration layer 20 is installed, only the first anti-vibration ball 21 is positioned on the slab 10, and the first lower convex portion 24', which is the lowest part of the first anti-vibration plate 22, The bottom surface has a predetermined gap with the slab 10. Since the first anti-vibration layer 20 has a plurality of first anti-vibration plates 22, the first anti-vibration plates 22 are installed so that there is no gap between adjacent first anti-vibration plates 22.

The first anti-vibration layer 20 may be formed on the entire surface of the slab 10, and the second anti-vibration layer 30 may be formed thereon. However, the second anti-vibration layer 30 may be formed in a state in which the first anti-vibration layer 20 is not completely formed.

The second anti-vibration layer 30 is formed such that the second anti-vibration hole 31 is positioned in the partition wall 28 in the first upper concave portion 24 of the first anti-vibration plate 22. ) is placed on the first anti-vibration plate 22. At this time, one second anti-vibration plate 32 does not correspond to one of the first anti-vibration plates 22, and one second anti-vibration plate 32 is positioned on a plurality of first anti-vibration plates 22. The anti-vibration plate 22 and the second anti-vibration plate 32 are displaced. Such a structure is well shown in FIG. 8 .

A mortar layer 40 is formed on the second anti-vibration layer 30 . A boiler pipe 42 may be located in the mortar layer 40. The mortar layer 40 is formed on the second anti-vibration plate 32, and the thickness of the mortar layer 40 at the position corresponding to the second body plate 33 and the second upper concave portion 34 ) The thickness of the mortar layer 40 at the corresponding position is different. That is, the thickness of the mortar layer 40 at the position corresponding to the second upper concave portion 34 becomes thicker. A floor finishing material 50 may be positioned on the mortar layer 40 .

In this configuration, when an impact is applied to the floor finishing material 50, the impact is transmitted to the second anti-vibration layer 30 through the mortar layer 40, as indicated by the dotted line arrow in FIG. Impact is transmitted to the first anti-vibration layer 20 via the second anti-vibration plate 32 and the second anti-vibration sphere 31 .

In the first anti-vibration layer 20, an impact can pass through the first anti-vibration plate 22 and the first anti-vibration ball 21. In this way, the second anti-vibration plate 32 and the second anti-vibration ball 31 , the first anti-vibration plate 22 and the first anti-vibration sphere 21 may absorb impact. Therefore, the impact applied to the floor finishing material 50 can be removed without being transmitted to the slab 10, and even if some of the unremoved impact is transmitted to the slab 10, the impact is relatively small and transmitted to the lower floor Noise between floors can be minimized.

Meanwhile, in the embodiments shown in FIGS. 9 and 10 , a third anti-vibration layer 130 and a fourth anti-vibration layer 140 may be further formed between the second anti-vibration layer 30 and the mortar layer 40 . In this case, the third anti-vibration layer 130 consisting of the third anti-vibration ball 131 and the third anti-vibration plate 132 is placed on the second anti-vibration layer 30, and then the fourth anti-vibration ball ( 141) and the fourth anti-vibration plate 142 are placed on the third anti-vibration layer 130.

In this case, the impact applied to the floor finishing material 50 is absorbed while passing through the fourth anti-vibration layer 140, the third anti-vibration layer 130, the second anti-vibration layer 30, and the first anti-vibration layer 20, Little may be transferred to the slab 10 .
