Description

Floor mat for preventing noise between floors of building having air layer

The present invention discloses a floor mat for preventing noise between floors having an air layer.

In general, the floor impact sound reduction mat is laid on the floor of a living room or room to reduce or block the floor impact sound of a multi-story building such as an apartment house to mitigate the transmission of the impact sound to the lower floor, and is also called a soundproofing mat or sound-absorbing mat.

Meanwhile, in order to solve the problem of noise between floors in a multi-story building, standards for housing construction standards, etc., have established and implemented a standard to be below a certain decibel, but the standard is insufficient and it is becoming a social problem due to disputes between neighbors due to noise between floors.

In order to solve the noise problem between floors, Korean Patent Publication No. 10-1765870 introduces a 'mat for preventing noise between floors'. The mat for preventing noise between floors of the prior literature includes a floor layer forming an air layer between the living room floor surfaces, a buffer layer integrally stacked on the upper surface of the floor layer, and a surface layer integrally stacked on the upper surface of the buffer layer. It has an excellent absorption effect of vibration or impact sound, which shows the advantage of being able to effectively block the transmission of vibration or impact sound to the lower layer.

However, the mat for preventing inter-floor noise of the prior literature is configured so that the floor layer on which the air layer is formed is in direct contact with the floor of the living room, so that the air layer is easily damaged or worn out, or foreign substances present on the floor surface of the living room are easily introduced into the air layer to prevent foreign substances. There is a disadvantage in that the mat is damaged or corroded, thereby reducing durability.

In addition, in the mat for preventing interlayer noise of the prior literature, the bottom layer in which a plurality of filament yarns are densely woven between the upper and lower fabrics is directly coupled to the buffer layer.

In addition, the interlayer noise prevention mat of the prior literature has a problem in that the space formed on the floor layer is easily damaged by frequent external pressure, and thus the noise blocking effect is lowered during long-term use.

The present invention and the technical problems achieved by the practice of the present invention will be made clear by the preferred embodiments described below. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

It should be understood that the differences between the embodiments described below are not mutually exclusive. That is, without departing from the spirit and scope of the present invention, the specific shapes, structures and characteristics described may be implemented in other embodiments with respect to one embodiment, and the location of individual components within each disclosed embodiment Alternatively, it should be understood that the arrangement may be changed, and similar reference numerals in the drawings refer to the same or similar functions over several aspects, and the length, area, thickness, and the like may be exaggerated for convenience. In the description of this embodiment, expressions such as up, down, before, after, etc. indicate positions or directions relative to each other, and their technical meanings are not limited to dictionary meanings.

1 is a partially exploded perspective view showing a floor mat for preventing noise between floors according to an embodiment of the present invention, FIG. 2 is an enlarged plan view of a base network, which is a main part of FIG. 1, and FIG. 3 is a floor for preventing noise between floors of FIG. 1 It is a cross-sectional view showing the mat, and FIG. 4 is an enlarged view showing the weave structure of the yarn forming the noise barrier layer, which is the main part of FIG. 3 .

As shown in these figures, the floor mat for preventing interlayer noise of this embodiment includes a noise barrier layer 100, an adhesive reinforcement layer 200 coupled to the noise blocking layer, a buffer layer 300 coupled to the adhesive reinforcement layer 200, and a buffer layer and an image layer 400 formed on the surface. The floor mat for preventing interlayer noise forms a symmetrical structure in which the adhesive reinforcement layer 200 , the buffer layer 300 , and the image layer 400 are sequentially coupled to both sides around the noise blocking layer 100 .

Specifically, the noise blocking layer 100 is configured to form an air layer 140 having a predetermined thickness to block noise from being transmitted and at the same time to have a cushioning function on the floor mat, and is arranged to be spaced apart from each other at a predetermined interval. and a pair of first and second base nets 110 and 120 forming a mesh structure, and a support yarn 130 connecting the first and second base nets 110 and 120 and supporting them to maintain a predetermined distance.

Referring to FIG. 2 , the first and second base networks 110 and 120 may be composed of common fiber yarns 111 forming multiple layers. In the first and second base networks 110 and 120 , the fiber yarns 111 and 121 forming a plurality of layers are woven in a rectangular shape, and square-shaped intervals 112 and 122 may be formed between the plurality of fiber yarns. In this case, the fiber yarns 111 and 121 may be woven in a rhombus shape or a honeycomb shape in addition to a rectangular shape. Such first and second base networks 110 and 120 allow the support yarn 130 to be easily and firmly coupled.

The support yarn 130 is woven and coupled to each fiber yarn 111 and 121 while reciprocating between the first base network 110 and the second base network 120 , and the first base network 110 and the second base network 120 . ) to maintain a state spaced apart at a predetermined interval to secure an air layer 140 for blocking noise therebetween. The support yarn 130 is composed of a filament yarn having a higher restoring force than a fiber yarn.

4, the support yarn 130 is a 'V' structure (or 'W structure) of the fiber yarn 111 of the first base network 110 and the fiber yarn 121 of the second base network 120 . Connect by round trip. Accordingly, the fiber yarns 111 of the first base mesh 110 are supported by the fiber yarns 121 of the second base mesh 120 by the support yarns 130 that form an inclined structure on both sides, and likewise the second base. The fiber yarn 121 of the net 120 is also supported by the fiber yarn 111 of the first base net 110 by the support yarn 130 forming the inclined structure on both sides.

In this way, the first base net 110 and the second base net 120 are supported by the support yarn 130 that repeats in a 'V' structure, thereby stably maintaining the spacing of the air layer 140 against the pressure applied from the outside. can keep

When the support yarn 130 simply connects the first base network 110 and the second base network 120 in the vertical direction (z-direction), when the vertical structure is damaged by an impact or pressure applied from the outside, the support yarn ( Since it is difficult to restore 130 in the vertical direction, the contracted air layer 140 is not restored and is damaged.

However, when the support yarn 130 is repeatedly connected in a 'V' structure to support the first base network 110 and the second base network 120 , since they are also supported between the adjacent support yarns 130 , the upper and lower ends Even if an external force is applied in the direction (z-direction), it can be restored, and eventually, even if the air layer 140 is temporarily compressed, it can be easily restored back to the original interval.

The support yarn 130 having such a 'V' structure may be connected in any one or both directions of a horizontal direction (x-direction) and a vertical direction (y-direction). In addition, in the plurality of supporting yarns 130 connected in the horizontal or vertical direction, the supporting yarns 130 adjacent to each other in the vertical or horizontal direction may be formed at positions shifted from each other.

The adhesive reinforcing layer 200 is configured to adhere the noise blocking layer 100 , and in this embodiment is composed of a sponge layer. The first and second base networks 110 and 120 constituting the adhesive surface of the noise barrier layer 100 are made of a plurality of fiber yarns 111 and 121, and since these fiber yarns 111 and 121 form a mesh structure, the buffer layer It is not easily adhered to (300).

Accordingly, the adhesive reinforcement layer 200 made of a sponge layer is adhered to the first and second base networks 110 and 120 on one surface, and to the buffer layer 300 on the other surface. This adhesive reinforcing layer 200 is a porous nonwoven fabric such as a sponge, and since it has low hardness and is surface-adhesive, it easily adheres the first and second base networks 110 and 120 of the mesh structure and at the same time easily adheres to the buffer layer 300 . it could be

In addition, since the adhesive reinforcement layer 200 made of a sponge layer has cushioning and buffering functions, there is also an effect of reinforcing the functions of the noise blocking layer 100 and the buffering layer 300 . A hot melting film may be used for bonding the noise blocking layer 100 and the adhesive reinforcement layer 200 .

The buffer layer 300 is configured to protect the noise prevention layer from the external environment and at the same time perform a cushioning function on the floor mat. The buffer layer 300 for this purpose is composed of a material such as a resin foam that can block absorption or inflow of external substances while having cushioning and restoring force at the same time, and may be composed of, for example, an epoxy foam or an EVA foam.

The buffer layer 300 preferably has a thickness of at least 50% to 100% compared to the thickness of the air layer 140 formed by the noise blocking layer 100 . If it has a thickness of less than 50% compared to the thickness of the air layer 140 of the buffer layer 300, it may be damaged as it repeats the contraction and restoration in response to the air layer 140 that is repeatedly contracted and restored according to an external shock or pressure. concerns are rising In addition, when the buffer layer 300 has a thickness exceeding 100% compared to the thickness of the air layer 140 , the cushioning action of the air layer 140 is absorbed by the buffer layer 300 , so that the cushioning effect by the air layer 140 is reduced. There are disadvantages. A hot-melting film may be used for adhesion between the buffer layer 300 and the adhesion reinforcement layer 200 .

The image layer 400 is formed on the surface of the buffer layer 300 and decorates the exterior of the floor mat. The image layer 400 may be formed by printing or transferring a specific image on the surface of the buffer layer 300 , and an uneven structure for preventing slippage may also be formed.

The floor mat for preventing interlayer noise having the above configuration includes the air layer 140 of a predetermined thickness in which the noise barrier layer 100 is formed by the support yarn 130, so that the transmission of noise generated from both surfaces is effectively blocked. and provides a comfortable feeling of use to the user with the excellent cushioning function of the air layer 140 . In addition, the support yarn 130 forming the air layer 140 has excellent restoring force, so that the air layer 140 can be restored to its original state against repeated external pressure to improve durability of the floor mat.

As described above, although exemplary embodiments of the present invention have been illustrated and described, various modifications and other embodiments may be made by those skilled in the art. All such modifications and other embodiments are intended to be contemplated and included in the appended claims without departing from the true spirit and scope of the present invention.
