Description

TECHNICAL FIELD [0001] The present invention relates to flooring for preventing interlayer noise and floor construction method using the same.

The present invention relates to a flooring for preventing interlayer noise which is applied to a concrete slab of a building and a floor construction method using the flooring. In particular, it is possible to intercept and suppress the noise transmission between the floors and to increase the adhesion area with the insulation layer, And a floor construction method using the same.

Interlayer noise refers to the noise pollution that occurs mainly in multi - family houses or apartments. Among the interstory noises, the floor impact sound can be classified into light impact sound and heavy impact sound. In the past, in the life focused on a single house, problems began to arise due to the generalization of apartment houses such as apartments. Especially, the floor impact sound (solid transmission sound) generated by the direct impact on the concrete surface among the interstory noise is easily transmitted to the adjacent generation. These noises are mainly the sound of children playing in the upper story and the sound of moving or falling objects. As with other noise pollution, interstep noise has an adverse effect on mental and physical health, which causes social problems such as many problems and complaints among neighboring residents.

As a background of the present invention, the Korean Registered Utility Registration No. 20-0403469 (dual floor structure for interlayer noise and vibration isolation), which is formed of expanded polystyrene and has a foaming magnification of 15 to 40 g / A first buffer plate having a concavo-convex portion on one surface thereof; A second buffer plate contacting with one surface of the first buffer plate, formed of foamed polypropylene, having a foam ratio of 15 to 25 g / L and having a plurality of column members on the bottom surface; And a mortar that is applied to the upper surface of the first buffer plate with a predetermined thickness. However, the above background art has a problem that the floor height is increased as a double structure of the buffer plate, so that the indoor floor height is reduced.

Another technology to be a background of the present invention is Korean Patent Registration No. 10-0977168 (Elastic flooring for preventing noise between layers), which is composed of a square or rectangular plate and connected to each other through a connecting body; An intermediate cushion plate attached to a bottom surface of the wooden panel and made of a rubber material or a synthetic resin material and having protrusions formed at equal intervals on the upper and lower surfaces thereof, An upper and a lower side perforated sound insulating plate attached to the bottom surface of the panel and closely contacting the bottom surface of the interlayer slab, and an upper and a lower side perforated sound insulating plate bonded together between the upper and lower surfaces of the intermediate cushion plate and the upper and lower perforated sound insulating plates, And a sound absorbing material attached to a side edge of the noise preventing panel.

However, in the latter background technique, the filling material is filled both on the upper and lower surfaces of the middle cushion plate, and the contact between the filling material and the intermediate cushion plate is formed in a plane, which limits the suppression of noise transmission. In addition, a complex addition of a single component leads to a complicated construction, which increases fabrication costs and construction costs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto.

As shown in FIGS. 1 and 2, the flooring for preventing noise between walls 10 according to the present invention may be made of a material having elasticity such as ethylene vinyl acetate (EVA) or urethane foam.

The flooring for preventing interlayer noise 10 can be implemented in all of four forms by the combination of the hexagonal protrusion 14 of FIG. 3 formed on the plate-like plate 12 and the hemispherical protrusion 16 of FIG.

As shown in Figs. 3 and 6, a hexagonal protrusion 14 is formed on the upper surface of the plate-shaped plate 12 and hemispherical protrusions 16 are formed on the lower surface thereof, as shown in Figs. 3 and 6, Like projections 16 are formed on the upper surface of the plate-like member 12 and hexagonal protrusions 14 are formed on the lower surface of the plate member 12. In the third embodiment, the upper surface 12a of the plate- And the hexagonal protrusion 14 is formed on the lower surface 12b thereof. The fourth embodiment is a configuration in which the upper surface 12a of the plate-shaped valve element 12 is made flat and the hemispherical protrusion 16 is formed on the lower surface 12b thereof, .

The shape, structure and arrangement relationship of the hexagonal protrusion 14 and hemispherical protrusion 16 formed in the four forms of the interlaminar noise preventing floor material 10 are all the same, and therefore, the embodiment of the first embodiment of the interlaminar sound insulating floor material 10 .

<Examples>

As shown in FIGS. 1 to 5, the flooring for preventing noise between walls 10 of the present embodiment is formed by repeatedly forming a hexagonal protrusion 14 having a hexagonal shape protruding from the upper surface 12a of the plate- . In addition, the flooring for preventing noise between buildings 10 has a plurality of hemispherical protrusions 16 protruding from the lower surface 12b of the plate-like member 12 with a predetermined pattern.

The hexagonal protruding portion 14 is composed of six column protrusions 14a located at hexagonal corner portions and a curved connecting portion 14b connecting the column protrusions 14a to each other. The curved connecting portion 14b is arcuate by a radius of curvature to interconnect the adjacent column protrusions 14a. Therefore, the curved connecting portion 14b interconnects the adjacent column projections 14a and 14a to strengthen the posture of the column projection 14a.

As shown in Figs. 5 and 7, the hemispherical protrusion 16 has a large hemispherical projection 16a formed by large and small spherical radii R1 and R2 relatively large in the center, and a small hemispherical projection 16b formed around the hemispherical projection 16 has a hexagonal angle They are arranged at a vertex and arranged with a certain pattern forming a polygonal array. The large hemispherical protrusion 16a and the small hemispherical protrusion 16b have the same hemispherical shape with a difference in size depending on spherical radii R1 and R2. At this time, the large hemispherical projections 16a are positioned at the center of the back surface of the hexagonal projection 14 in a one-to-one correspondence with the respective hexagonal projections 14, and the small hemispherical projections 16b are arranged on the back side corresponding to the respective column projections 14a .

Therefore, the small hemispherical projection 16b is arranged in the periphery of the large hemispherical projection 16a, and when the vertices of the six small hemispherical projections 16b are connected to each other by a line segment, a hexagon is formed. At this time, the large hemispherical projection 16a protrudes higher than the relatively small hemispherical projection 16b by a predetermined height h (see FIG. 5).

As described above, the flooring for preventing noise between buildings 10 has a hexagonal protrusion 14 arranged on one surface of the plate-shaped plate 12, and a plurality of hemispherical protrusions 16 are arranged on the other surface of the plate- Therefore, when the concrete slab is installed on the concrete slab, its function varies depending on the installation position.

That is, when the flooring 10 for preventing the interlaminar noise is installed such that the hexagonal protrusion 14 is located on the upper surface as shown in FIG. 5, the hemispherical protrusion 16 is in point contact with the concrete slab 100. Therefore, when the large hemispherical protrusion 16a of the hemispherical protrusion 16 is deformed by the action load, the small hemispherical protrusion 16b contacts the concave slab 100 Minimizing noise transmission.

At this time, the hexagonal protrusion 14 on the upper surface increases the adhesion with the foamed concrete forming the heat insulating layer 20 as shown in FIG. 12, thereby suppressing cracking of the foamed concrete.

On the contrary, when the floor material 10 for preventing the interlaminar noise is installed so that the hexagonal protrusion 14 is located on the lower surface as shown in FIG. 8, the column protrusion 14a constituting the hexagonal protrusion 14 is placed on the concrete slab 100 Point contact. Accordingly, the noise transmission is blocked and suppressed by minimizing the contact area between the floor material 10 for preventing noise between the floor and the concrete slab 100. Also, due to the arch effect of the curved connecting portion 14b, the rigidity of the flooring 10 for preventing the interlaminar noise increases, thereby suppressing sagging and deformation. At this time, the contact area is further widened by the hemispherical protrusion 16, so that the adhesion between the flooring material 10 and the foamed concrete of the heat insulating layer 20 is increased and cracking of the heat insulating layer 20 is suppressed.

Here, 'point contact' means that the highest vertex portion of the hexagonal protrusion 14 or the hemispherical protrusion 16 is interposed.

A floor construction method to which the flooring for preventing the interlaminar noise 10 constructed as described above is applied will be described.

First, as shown in FIG. 11, an interlayer noise preventing floor material 10 is provided on the upper surface of a concrete slab 100. The flooring for preventing noise between buildings 10 is installed in the form of a tile on the upper surface of the concrete slab 100 with a quantity corresponding to the upper surface area of the concrete slab 100.

In the present embodiment, the flooring for preventing noise between the floor 10 is selected such that the hexagonal protrusion 14 on the upper surface of the plate-shaped plate 12 and the hemispherical protrusion 16 on the lower surface thereof are provided, but the above- Of course.

Then, a foamed mortar (No. 10-105557) is placed on the upper surface of the flooring for preventing noise 10, and the heat insulating layer 20 is applied. Herein, the bubble mortar may be applied not only to known bubble mortar but also to the 'heat insulating material composition' described in the above-mentioned Japanese Patent No. 10-1055557 and Japanese Patent No. 10-1268439.

Next, a hot water pipe 31 is installed on the upper surface of the heat insulating layer 20, and a well-known mortar 32 is placed on the hot water pipe layer 30 to construct the hot water pipe layer 30.

Finally, a known finishing material 40 is installed on the upper surface of the hot water piping layer 30. The finishing material 40 is not limited to a specific kind but satisfies required performance such as designability, durability, workability, usability and sanitary property. For example, the finishing material 40 may be a wood finishing material, a PVC flooring material, a stone material, a clay tile, But is not limited thereto. Wood finishing materials can be wood flooring, plywood flooring, and reinforced flooring.

On the other hand, in order to distinguish each construction layer (layer) on one side wall of the concrete slab 100 in the present construction method, a color tape 50 for a layer is installed before the installation of the flooring 10 for preventing an inter- desirable. In this case, the color tape 50 for a layer has different colors 51, 52, 53 and 54 for each section corresponding to the construction layer on one side thereof and has an adhesive layer coated with an adhesive on the other side. Therefore, when the color tape 50 for a layer is applied to the construction, the convenience of the construction is improved and the precision is improved by distinguishing the color layers.

According to the floor construction method using the flooring for preventing the inter-layer noise, the hexagonal protrusion 14 of the flooring 10 for preventing noise is located on the upper surface so that the hemispherical protrusion 16 comes into contact with the concrete slab 100. The contact area between the flooring 10 for preventing noise and the concrete slab 100 is minimized and the transmission of noise from the upper layer to the lower layer is suppressed. When the large hemispherical protrusion 16a of the hemispherical protrusion 16 is deformed by the action load (impact load) of the upper layer, the small hemispherical protrusion 16b comes into contact with the concave slab 100, Dissipates energy to minimize noise transmission. At this time, the hexagonal protrusion 14 on the upper surface increases the adhesion force with the foamed concrete constituting the heat insulating layer 20, so that cracking of the heat insulating layer 20 is prevented.

As another embodiment, the flooring materials 10a and 10b for preventing the interlaminar noise are stacked in the upper and lower layers so that the hexagonal protrusion 14 and the hemispherical protrusion 16 are located opposite to each other as shown in Figs. 14A to 15, The double-faced tape 60 is adhered along the flat upper surface side bonding surface of the preventing floor member 10b and the upper side floor noise preventing floor material 10a is bonded to the lower side floor noise preventing floor material 10b So as to be arranged in a mutually offset manner.

14A and 14B illustrate a construction method of laminating the flooring materials 10a and 10b for preventing interlayer noise according to the present invention in the upper and lower layers. Fig. 14B is a view showing a state in which the floor material 10a for preventing the upper side of the upper layer adhered to the double-faced tape 60 is attached. Fig. And the bottom layer noise preventing floor material 10a and 10b are bonded to each other through the double-sided adhesive tape 60. As shown in Fig.

When the upper and lower layers of the noise preventing floor material 10a and 10b are laminated in layers in the upper and lower layers, not only the absorption rate of the interlayer noise can be increased, but also the upper and lower layer- And 10b) can be obtained.

In the present embodiment, the hexagonal protrusions 14 are located above and the hemispherical protrusions 16 are disposed underneath. However, if the installation order of the floor materials 10a and 10b for preventing the noise between the upper and lower layers is changed, It is possible.

Meanwhile, in the case where a recessed portion that is not smooth is generated in the concrete slab 100, a step of further laminating the double-faced tape 60 may be included to prevent the flooring for preventing the interlayer noise from sagging. At this time, the double-sided tape 60 is stacked as much as possible to offset the depth of depression. The laminated position of the double-sided tape 60 becomes a flat upper surface of the flooring for preventing the interlaminar noise from being recessed above the concrete slab 100. [

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the above teachings. will be. The invention is not limited by these variations and modifications, but is limited only by the claims appended hereto.
