DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a floor structure for reducing interlayer noise according to the present invention will be described in detail with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are included to provide a further understanding of the technical concept of the present invention, are incorporated in and constitute a part of the specification, and are not intended to limit the scope of the present invention.

[First embodiment, a state in which the lower strut and the upper strut are separated]

FIG. 1 is a perspective view of a floor, a cushioning material, a lower strut and a joist of the first embodiment of the present invention, and FIG. 2 is a cross-sectional view of a floor structure for reducing interlayer noise according to the present invention.

1 and 2, the first embodiment of the present invention includes a lower strut 100, a joist 200, a panel 300, a heating fluid flow unit 400, and a bottom plate 500 .

1 shows a bottom surface 10 and a cushioning material 110 which will be described later, in which the lower strut 100, the joist 200, the lower strut 100 are installed, The outline of the arrangement of the joining line 100 and the joining line 200 can be known.

As shown in FIG. 2, the lower strut 100 is installed on the bottom surface 10, while supporting structures located on the upper side of the lower strut 100, To form a lower space 20 at the top of the bottom surface 10.

The lower strut 100 may be of a prefabricated type and may include a bottom seating plate that is in close contact with the bottom surface 10, a spacing bolt whose one end is engaged with the bottom seating plate, and an upper support coupled to the other end of the spacing bolt .

In addition, the lower strut 100 is adjustable in height according to the condition of the bottom surface 10. Specifically, the bottom seating plate is provided with a female threaded portion formed with a spiral in its center portion, and a coupling hole is formed in a central portion of the upper support body, so as to be coupled with one end and the other end of the distance spaced bolt. The spacing-maintaining bolts may have different lengths. When the bottom surface of the workpiece is not entirely flat, the spacing-maintaining bolts are arranged on the upper side of the lower support 100 so as to have a flat height. . In addition, it has a screw structure that is easy to separate and combine, so that it is possible to select and assemble the distance interval bolts of an appropriate length immediately at the construction site according to the bottom surface condition of the installation target, .

The lower strut 100 may be formed of a rigid material, such as reinforced concrete or metal, since the lower strut 100 must support structures located on the upper side.

In the lower space 20, a water pipe or an electric pipe is installed. As described in the background art, conventionally, a concrete layer is formed directly on the upper side of the bottom surface 10, a reinforcing bar is disposed on the concrete layer, and a water pipe or an electric pipe is installed around the reinforcing bar. There is a problem that installation, repair, or replacement of the water pipe or electric pipe is inconvenient as well as troublesome. However, when the water pipe or the electric pipe is installed in the lower space 20, there is an advantage that it is not necessary to have a different structure compared to the conventional concrete and reinforcing bar, and the repair or replacement is simple.

As shown in FIGS. 1 and 2, a cushioning material 110 having elasticity is installed between the bottom surface 10 and the lower strut 100. The cushioning material 110 is provided to reduce vibration and noise generated by a user or other factors, and is formed of an elastic material. The material of the cushioning material 110 is generally inexpensive and can be variously used. However, the rubber is deformed by the load transmitted to the lower strut 100 when it is used for a long time, and its elasticity is reduced. Thus, the buffer material 110 shown in FIGS. 1 and 2 may be formed of silicon. The silicone is less likely to be reduced in elasticity even when it is used for a long time, and the life and durability of the cushioning material 110 are improved.

As shown in FIG. 1, the lower strut 100 includes an upper side plate and a lower side plate disposed in parallel to each other in a disk-like shape, and includes a screw column connecting the upper side plate and the lower side plate. The screw post, the upper side plate, and the lower side plate are screwed together, and the height of the lower support 100 can be adjusted by adjusting the degree of screwing. The configuration in which the height of the lower strut 100 is adjusted by adjusting the screws is disclosed in the applicant's registration utility model No. 20-0477447 ("Marutle support device with excellent workability and system floor constructed using it ", 2014.04. It is easy to adjust the height of the lower strut 100. In order to construct other constructions including the long strut 200 on the upper strut 100, There is an effect that is easy to match.

As shown in FIG. 1, a plurality of the joist lines 200 are installed at the upper part of the lower strut 100 so as to cross perpendicularly to the lower struts 100, Are arranged in parallel at regular intervals. The joist line 200 serves to support the panel 300, the heating fluid flow unit 400, and the bottom plate 500, which are located on the upper side, and is also connected to the wall to secure the coupling.

As shown in FIG. 2, the panel 300 is manufactured in advance and is installed in contact with the joist line 200 on the upper side of the joist line 200. The panel 300 may be made of foamed concrete or made of a hard insulating material . That is, the panel 300 is constructed in block form and used for construction.

The foamed concrete used for the panel 300 is formed by mixing foamed foam such as aluminum powder with concrete and is lightweight compared with the conventional concrete. However, it has advantages such as heat insulation, workability and fire resistance, There are weak drawbacks. When the panel 300 is preliminarily manufactured with the foamed concrete, it is light in weight and easy to apply. In addition, it is possible to prevent the heat generated in the heating fluid flow unit 400 installed on the upper side of the panel 300 . When the panel 300 is made of foamed concrete, the waterproof layer is separately formed so that water can not flow into the panel 300. The waterproof layer is formed separately from the panel 300 when the panel 300 is made of foamed concrete because the foamed concrete is strong in absorbency and becomes heavy when water is absorbed.

The panel 300 may be formed of a lightweight insulation material. The foamed concrete is also a kind of lightweight insulation material. The material for forming the panel 300 may be a ceramic mat, styrofoam, or glass fiber.

As shown in FIG. 2, the heating fluid flow unit 400 is arranged on the upper surface of the panel 300, and may include a heating pipe 410.

The heating pipe 410 is configured to dissipate heat while passing hot water for heating and to transmit the heat to the upper side, and is included in a general floor structure. The heating fluid flow portion 400 shown in FIG. 2 can be installed by a dry method in which a plurality of gravels are filled in the space between the heating pipes 410. When the heating fluid flow portion 400 is filled with gravel other than concrete, the time and environment required for concrete curing (environment in which the temperature is a visual image) are not needed, and the construction time is shortened and the construction is simple. Generally, in order to cure after pouring, the temperature should be the image, and if the temperature falls below freezing, the water contained in the concrete will not freeze and cure.

When the heating fluid flowing part 400 is made of gravel, the bottom plate 500 installed on the heating fluid flowing part 400 can not be horizontally supported. Therefore, the heating fluid flowing part 400 is further provided with a separate upper support 420. The upper strut 420 is installed between the panel 300 and the bottom plate 500 to support the bottom plate 500 and a plurality of upper struts 420 are installed on the upper side of the panel 300. The height of the upper strut 420 is the same as that of the heating fluid flowing part 400. The upper struts 420 may be formed in the same longitudinal direction as the lower struts 100 shown in FIG. 1, or may be formed in a plurality of columns, and may have the same configuration as the lower struts 100 And may be made of a material having rigidity similar to that of the lower strut 100.

As shown in FIG. 2, the bottom plate 500 is installed on the upper part of the heating fluid flow unit 400, and the user directly touches the upper surface. The bottom plate 500 is supported by the upper struts 420 for structural stability because the heating fluid flow portion 400 is formed of gravel. The bottom plate 500 is made of the same material as wood, which is a general top plate material.

When the heating fluid flowing part 400 is formed of gravel, even if the heating fluid flowing part 400 is finished by the bottom plate 500, the bottom plate 500 may not be damaged or horizontally aligned due to the uneven surface characteristics of the gravel, It may not be smooth. In order to prevent this, a buffer part 600 is formed between the heating fluid flow part 400 and the bottom plate 500 as shown in FIG.

The buffer part 600 is formed using a buffer mat made of an elastic material such as sponge or rubber. The buffer part 600 prevents the bottom plate 500 from being damaged according to the material of the heating fluid flowing part 400. When the user presses the surface of the bottom plate 500, It is possible to prevent the feeling of the rough surface of the display unit 400 from being felt, thereby improving the feeling of use. Also, the buffer part 600 is formed as a buffer mat, thereby reducing the inter-layer noise and inter-layer vibration.

In the first embodiment of the present invention shown in FIG. 2, the lower strut 100 and the upper strut 420 are spaced apart from each other. The vibration and noise generated by the user at the top of the bottom plate 500 are transmitted to the heating fluid flow unit 400. More specifically, the vibration and noise are transmitted to the heating fluid flow portion 400 and the upper support 420 formed of gravel, wherein the heating fluid flow portion 400 is formed of gravel and includes a plurality of voids therein Therefore, the wavelength is not easily transmitted. Accordingly, vibration or noise is transmitted to the upper strut 420 formed of a single medium. The upper strut 420 and the lower strut 100 are not integrated with each other, so that vibration or noise transmitted to the upper strut 420 Is transmitted to the lower strut 100 through the panel 300 and the joist line 200. In this process, most of the vibration or noise disappears, and the vibration or noise transmitted to the lower space 20 disappears.

[Second embodiment: state in which the lower strut and the upper strut are connected]

Hereinafter, a second embodiment of the floor structure for reducing interlayer noise according to the present invention will be described with reference to the accompanying drawings.

FIG. 3 shows a second embodiment of the bottom structure for reducing interlayer noise according to the present invention. As shown in FIG. 3, the second embodiment differs from the first embodiment in that the lower strut 100 And the upper struts 420 are integrally connected to each other. At this time, the upper struts 420 are columnar and disposed in a space formed between the joists 200. In addition, a separate hole is formed in the panel 300 to allow the upper strut 420 to pass therethrough.

In the second embodiment, the upper strut 420 and the lower strut 100 are connected and integrated to facilitate the construction. In this case, the vibration or noise generated in the bottom plate 500 can be easily transmitted to the bottom surface 10 through the upper support 420 and the lower support 100. That is, in order to facilitate the construction, the second embodiment is selected and constructed. In order to further reduce the noise, the first embodiment may be selected and installed.

As shown in FIG. 3, the buffer part 600 may also be formed in the second embodiment.

[Third embodiment: state in which the heating fluid flow portion is formed of mortar]

Hereinafter, a third embodiment of the floor structure for reducing interlayer noise according to the present invention will be described with reference to the accompanying drawings.

4 shows a third embodiment of the floor structure for reducing interlayer noise according to the present invention. As shown in FIG. 4, the third embodiment differs from the first embodiment in that the heating fluid flow portion 400 are formed on the upper surface of the panel 300 and a heating pipe 410 and a mortar for mounting the heating pipe 410. Mortar is a type of concrete that, like concrete, undergoes the process of casting and curing. Accordingly, as shown in FIG. 4, a plurality of the heating pipes 410 are arranged and a mold is formed, and then the mortar is poured and cured. Since the mortar is a material having a higher structural stability than the gravel, the upper strut 420 may be omitted.

The third embodiment is wet process because of the use of mortar, but its structural stability is higher than that of the first embodiment or the second embodiment.

As shown in FIG. 4, the buffer part 600 installed in the first embodiment and the second embodiment may not be installed in the third embodiment. This is because the bottom plate 500 is easily leveled when the heating fluid flowing unit 400 is formed of mortar and is not formed of the gravel of the heating fluid flowing unit 400 and is flat. However, the present invention is not limited thereto. Even when the heating fluid flow unit 400 is formed of mortar as in the third embodiment, the buffer unit 600 can be selectively installed according to the construction conditions or the user's selection.

The panel mounting step is a step of installing a panel 300 manufactured in advance on the joist line 200. The panel 300 may be a foamed concrete as described above, or may be a hard insulating material.

In the heating fluid flow unit construction step, the heating pipe 410 is disposed on the upper part of the panel 300 and the heating fluid flow unit 400 is installed. The heating fluid flow portion construction step can be divided into two cases, which are the first, second, and third embodiments of the floor structure for reducing the interlayer noise.

More specifically, in the heating fluid flow unit construction step, the heating pipe 410 is disposed on the upper part of the panel 300 to construct the first or second embodiment, and then the panel 300 The upper pillars 420 may be installed on the upper part of the main body 500 and the heating fluid flow part 400 may be formed by pouring gravel. At this time, the upper strut 420 may be connected to the lower strut 100, and the lower strut 100 is formed integrally with the upper strut 420, The structure for installing the pillars 420 may be omitted.

That is, the above-mentioned method is a method of being dry-constructed.

In addition, in the heating fluid flow portion construction step, the heating fluid flow portion 400 may be formed by placing and curing the mortar to construct the third embodiment. This method is a wet type method, unlike the above-mentioned dry type method.

In the step of installing the bottom plate, a bottom plate 500 is provided on the upper side of the heating fluid flowing unit 400 to complete the construction.

A buffering portion forming step of forming a buffering portion 600 above the heating fluid flowing portion 400 may be additionally performed between the heating fluid flowing portion construction step and the bottom plate installing step.
