Description

[0001] Interlayer Noise barrier [0002]

The present invention relates to a cushioning material for preventing interlayer noise, and more particularly, to a cushioning material for preventing interlayer noise, and more particularly, to a foamable cushioning plate which is excellent in sound insulation effect and undergoes excessive compressive deformation due to a load, The present invention relates to a cushioning material for preventing an interstice noise.

The conventional interlayer cushioning material is composed of a cushioning material 2 made of foamed resin material such as styrofoam or urethane foam having a predetermined size and thickness (approximately 10 to 30 mm).

The cushioning material 2 is laid on the slab 1 and the foamed concrete 3 is laid thereon. Then, the heating pipe 4 is installed, the finishing mortar 5 is cured and cured, ) And finish it.

When the load is applied to the interlayer cushioning material 2 made of a foamed resin material, compression deformation occurs due to the compressive force, which fails to satisfy the originally required thickness, and is hardened as much as it is compressed.

Particularly, when heat for heating is applied and the temperature rises, it becomes soft and the compression deformation is accelerated, so that the sound insulation effect is remarkably deteriorated.

Basically, when improving the sound insulation performance, it is possible to easily obtain the desired sound effect by softening the cushioning material like rubber. However, there is a concern that cracks are generated on the concrete floor installed thereon, and conversely, when the cushioning material is hardened There is a problem that compression deformation with respect to the load does not occur but the sound insulation effect is lowered. It is necessary to find a suitable optimum condition thereof. However, at present, it is in a state where the compression deformation against the load can not be prevented due to the characteristics of the material.

The object of the present invention is to solve the above-described problems of the prior art. The object of the present invention is to provide a cushioning material made of a foamed synthetic resin by combining separate parts, And to provide a cushioning material for preventing inter-layer noises having a semi-permanent durability.

It is another object of the present invention to provide a cushioning material for preventing noise between layers to uniformly transmit load in response to a change in height according to a finishing state of a slab.

In order to achieve the object of the present invention,

An elastic cushion foot comprising a support and a cushion extending in one end of the support;

A buffer cap covering the top of the support to secure a buffer space of the buffer;

The foamed synthetic resin plate having a plurality of insertion holes for receiving the elastic cushion foot;

The foamed synthetic resin sheet is laid on the slab and the elastic cushion foot having the cushioning cap on the upper part is inserted into the insertion hole.

Further, the cushioning material for preventing noise between layers according to the present invention is achieved by forming a coupling groove at the end of the support and coupling a buffer heel made of synthetic rubber rubber to the coupling groove.

In addition, the cushioning material for preventing noise between layers according to the present invention is formed by forming protrusions at the lower part of the foamed synthetic resin plate to the support part of the elastic cushion foot to form a floating structure.

 The insertion hole is formed by penetrating the elastic cushion foot in such a manner that the elastic cushion foot can ascend and descend according to the height of the surface of the slab.

The inventive interlayer cushion material having an elastic cushion foot is excellent in sound insulation effect, and there is a fear of compressive deformation with respect to a load. Particularly, a foamed synthetic resin having a material limit with a high possibility of compression deformation due to high temperature has a buffer part By reinforcing the separate elastic cushion pads, compressive deformation due to load and heat can be minimized while maintaining a high sound insulation effect, thereby providing a semi-permanent durability.

In addition, the present invention is advantageous in that the foamed synthetic resin is first applied at the time of construction, and the elastic cushion foot is inserted into the insertion hole formed at the top of the foamed synthetic resin.

In the present invention, the insertion hole of the foamed synthetic resin passes through the upper and lower portions, and the elastic cushion foot inserted into the upper portion of the insertion hole is vertically moved up and down according to the height of the slab and is closely attached to the bottom of the slab. And the like.

Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 6 is a cross-sectional view of the foamed synthetic resin material of the cushioning material according to the present invention, FIG. 7 is an embodiment of a foamed synthetic resin material of a cushioning material according to the present invention, and FIG. 8 is a sectional view showing the state of the cushioning material according to the present invention.

As shown in the drawings, the present invention is characterized in that the foamed synthetic resin plate 10 and the foamed synthetic resin plate 10 are arranged and inserted to absorb energy such as noise and impact noise, And an elastic cushion foot 20 for preventing compression to a value exceeding a limit that can not be restored by a load applied to the upper portion and an impact.

The foamed synthetic resin plate 10 can use various products such as EPS widely used for insulation and sound absorption at present.

A plurality of insertion holes (11) into which the elastic cushion foot (20) is inserted are formed in the foamed plastic plate (10). The insertion hole 11 may be formed when the foamed synthetic resin plate 10 is molded or may be formed through a post-process.

The insertion hole 11 may be formed so that the elastic cushion foot 20 can move up and down according to the surface height of the slab S. The insert hole 11 may have a size corresponding to the size of the elastic cushion foot 20 but may have a downwardly lowering limit so that the inner shape of the insertion hole 11 is limited to the lower end Is formed to be narrowed to the size of the supporter (21).

In addition, a protrusion 17 may be formed at the lower end of each insertion hole 11 of the foamed synthetic resin plate 10 to constitute a noise-preventing cushioning material of a floating structure having a floating shape at a predetermined interval in the slab.

The elastic cushion pads 20 are coupled to the plurality of insertion holes 11 formed in the foamed synthetic resin plate 10, respectively. The shape of the elastic cushion foot 20 is simply inserted into the insertion hole 11 of the foamed synthetic resin plate 10 to cushion while supporting a considerable part of the loads of concrete and various loads placed on the upper portion of the foamed synthetic resin plate 10 And functions to maintain the physical properties of the foamed synthetic resin sheet 10 without being deformed semi-permanently.

The elastic cushion foot 20 comprises a support 21 contacting the slab S and a cushioning portion 23 formed at one end thereof. The buffer part 23 is formed with a plate part extending around one end of the support and is divided into a plurality of notches 25 so as to have a buffer piece 24 between the notches 25. The cushion 24 attenuates the shock or noise energy transmitted from the upper portion to the slab S by using the self-elastic force. Therefore, it performs a function that is important for the sound insulation function.

The cushion 24 may have a circular arrangement at regular intervals around the elastic cushion foot 20, or may be symmetrical in both sides.

And a buffer cap 30 is formed on the upper portion of the insertion hole 11.

The cushioning cap 30 functions to block the upper portion of the elastic cushioning foot 20 so as to prevent the concrete from penetrating the upper portion of the elastic cushioning foot 20 or the insertion hole 11. Therefore, it can be constructed simply as an adhesive tape as shown by reference numeral 30-1 in FIG. 9, or it can be made of a synthetic resin rubber material, and can also be combined with a buffer function.

The sizes of the elastic cushion foot 20, the cushioning cap 30 and the insertion hole 11 are set such that the elastic cushioning foot 20 and the cushioning cap are inserted into the insertion hole 11, The elastic cushion foot 20 or the cushioning cap 30 or the cushioning cap 30 must be prevented from entering the gap between the elastic cushion foot 20 and the cushioning cap 30 and the insertion hole 11, It is preferable to form the corresponding size tightly.

In the cushioning material 100 according to the present invention having such a structure, the foamed synthetic resin plate 10 is closely attached to the upper part of the slab, and then taping is performed to the connection part between the cushioning materials to prevent the concrete water from leaking into the gap when the concrete is poured.

Subsequently, the elastic cushion foot 20 is inserted into each insertion hole 11 formed in the foamed synthetic resin plate 10 such that the support base 21 faces downward. At this time, it is preferable that the buffer cap 30 is coupled to the upper portion of the elastic cushion foot 20, but it is also possible to couple the buffer cap 30 after completion of the insertion of the elastic cushion foot 20. In any case, a certain space is maintained between the buffer cap 30 and the cutout groove 25 and the buffer 24 of the elastic cushion foot 20 so that the elastic force can be exerted.

If the height of the surface of the slab S is uneven, the elastic cushion foot 20 is further lowered so as to be brought into contact with the surface of the slab S.

When the cushioning material 100 of the present invention is installed on the slab S, foamed concrete A or mortar M is laid on the slab S as shown in FIG. If the foamed concrete (A) is to be laid, a mortar (M) is further placed thereon. When the mortar (M) is poured, the heating pipe (P) is buried.

The foamed concrete A or the mortar M is piled up on the foamed synthetic resin plate 10 to a predetermined thickness and is also filled in the upper portion of the buffer cap 30 on the elastic cushioning foot 20. [ If the lower end of the elastic cushion foot 20 does not contact the slab S, the lower end of the elastic cushion foot 20 is forcibly lowered by the weight of the foamed concrete A or the mortar M to be placed,

When the mortar (M) is cured, it is finished by installing a floorboard or floorboard after finishing the plastering.

When a load is applied to the cushioning material 100 according to the present invention, the load is uniformly transferred to the foamed synthetic resin sheet 10, and the foamed synthetic resin sheet 10 is compressed and shrunk. However, the shrinkage is very small. However, when there is a load such as furniture installed in a building, a larger load is applied to the portion, so that the foamed plastic plate 10 can be further contracted. Particularly, when a person moves or a load is moved, a larger load is applied, and the shrinkage phenomenon of the foamed plastic plate 10 will be increased. However, when the elastic cushion foot 20 is contracted to a certain depth or more, the elastic cushion foot 20 supports the load, so that the expansion resin is prevented from contracting beyond the restoration limit.

When the elastic cushion foot 20 is subjected to a load, the noise energy such as noise or impact is extinguished at the first cushioning cap 30 and the noise energy at the cushioning portion 23 of the second elastic cushioning foot 20 . That is, the noise energy transmitted to the elastic cushion foot 20 is lost due to the elastic action of the cushion piece 24.

On the other hand, a buffer heel 26 may be formed in the lower portion of the elastic cushion foot 20 to improve the buffering function. That is, the impact sound or noise transmitted to the support 21 of the elastic cushion foot 20 is such that the cushion heel 26 made of synthetic rubber rubber at the lower end of the elastic cushion foot 20 is attenuated.

At this time, since the buffer heel 26 is not covered with the end of the support but filled in the coupling groove 25, even if a large pressure is applied, the buffer heel 26 is not worn and its service life is semi-permanently maintained.
