BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a damping panel, a floor structure, and a damping panel,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a damping panel, a bottom structure, and a method of manufacturing a damping panel. More particularly, the present invention relates to a damping panel, .

Recently, the building type has been concentrated in multi-storey apartment buildings such as apartments and villas. Since the conflict between the residents due to the noise generated in the floor in the apartment building is becoming a major social problem, the floor impact sound blocking performance for ensuring a quiet living environment is more important than anything else.

Such a floor impact sound is classified into a heavy impact sound such as a beeping sound of children and a light impact sound such as a sound of pulling a chair. Here, it is recognized that the main cause of the interstory noise conflict is heavy impact sound, and reinforcing the structure such as increasing the thickness of the floor slab of the building is the only solution.

However, if the thickness of the floor slab of the building is increased, not only the quantity of the floor slab but also the weight of the building increases, and the dimensions of the main structural members such as columns, bases, and the like also increase. Therefore, it is necessary to increase the construction cost of the building and the construction cost, and the floor height of the building is also increased, which lowers the economical efficiency of the building.

The floor structure of the conventional apartment house is mainly composed of a wet method. The floor structure of the wet type method is, as shown in FIG. 1, a heat insulation material 11 installed on the floor slab 10 A lightweight foamed concrete 12, a finishing mortar 13, a finishing material 14, and a pipe 15.

However, in the floor structure according to the conventional wet method, there is no heat insulating material that can reduce the floor impact sound. Even if the heat insulating material is replaced with a cushioning material, there is no great effect in reducing the heavy impact sound. The deterioration of the foamed concrete may cause a problem of corrosion of the heat insulating material or the cushioning material.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a damping panel, a bottom structure, and a method of manufacturing a damping panel, which are configured to reduce an impact and absorb sound generated by the impact. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, in adding reference numerals to the constituent elements of the drawings, the same constituent elements are denoted by the same reference symbols as possible even if they are displayed on different drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

3 is a perspective view illustrating a damping panel according to an embodiment of the present invention. FIG. 4 is a cross-sectional view of a floor structure according to an embodiment of the present invention. This is an enlarged view.

Referring to the drawings, the damping panel 200 of the present invention includes a panel body 210 made of a steel plate, concavities and convexities formed adjacent to each other in the width direction and the longitudinal direction of the panel body 210, And a damping portion 220 in which a space portion 220a is formed to allow air to flow therethrough.

At this time, the panel body 210 may have a flat shape as a plate-like structure, and the damping portion 220 may be formed such that a plurality of concave portions and convex portions are disposed adjacent to both sides of the panel body 210 have. For example, it may be provided in a form similar to an egg plate.

More specifically, the damping portion 220 has a plurality of concave portions and convex portions formed on both sides thereof in the thickness direction of the panel body 210, and the concave portions and the convex portions are disposed in a plurality of mutually intersecting directions. The concavity and convexity of the damping portion 220 may have a polygonal cross section or a circular structure as shown in FIG.

The damping part 220 forms a space part 220a adjacent to each other. For example, referring to FIG. 4, a cross section of the damping portion 220 is formed in a quadrangular shape, a concave portion forms a space portion 220a, and the space portion 220a includes a convex portion So that air can flow.

With this configuration, when an impact sound is generated by the impact, the impact sound is transmitted through the air filled in the space portion 220a, and when the impact sounds generated in the neighboring space portion 220a meet each other, an interference effect is generated and the impact sound is attenuated It is effective. In addition, since all the space portions 220a are communicated, the impact sound generated by the impact is transmitted to the outer surface of the damping panel 200 through the space portion 220a without being transmitted to the lower portion, 300 to the outside.

A sound absorbing material (not shown) capable of absorbing noise may be filled in the space 220a of the damping unit 220. Since the damping panel 200 is provided with the space portion 220a on both sides thereof, the sound absorbing material can be filled in either one of both sides or both sides thereof. Alternatively, the two surfaces may be filled with different scratches.

The sound absorbing material absorbs a part of the sound energy hitting the surface of the material and reduces the reflection sound to be used in a place where noise is generated, thereby exhibiting soundproofing and damping effects. The space 220a may be filled with a rock surface, a glass wool, a text, a sponge, sand or the like having a high middle-damping ratio. Of course, the sound absorbing material is not limited thereto, and various materials excellent in soundproofing and damping effects can be filled.

The damping panel 200 constructed as described above can be utilized as a floor structure in a building, and furthermore, can be utilized in a side structure. Of course, the present invention is not limited thereto and can be applied to any structure requiring buffering and damping.

Hereinafter, a method of manufacturing the damping panel 200 constructed as described above will be described.

The method of manufacturing the damping panel 200 may be roughly divided into a body preparing step of providing the panel body 210 and a pressing step of pressing the panel body 210 to form the damping part 220 .

Here, the main body preparing step is a step of providing a flat panel body 210 made of a steel plate. The panel body 210 is provided with a steel plate for press working, and also, among rolls, Shape.

Next, the pressing step is a step of pressing the panel main body 210 to shape the damping part 220. Specifically, the press device includes concave and convex parts formed by intersecting concave parts and convex parts of the press device, The damping portion 220 may be manufactured by pressing the panel body 210 to form the concave and convex portions in the thickness direction of the panel body 210.

At this time, the pressing step may be formed by roll stamping. A method for manufacturing the damping panel 200 of the present invention by such a roll stamping includes, for example, an uneven shape on the outer circumferential surface of the upper roll, and a concavo-convex shape staggered from the unevenness of the upper roll on the lower roll The damping portion is formed as the panel body passes between the upper roll and the lower roll. Of course, the roll stamping method for manufacturing the damping panel is not limited thereto.

The manufacturing method of the damping panel 200 having the above-described structure is advantageous in that it can continuously produce an integral damping panel of the same material by roll stamping, particularly in the pressing step. Since the conventional damping panel is manufactured by welding or fastening a plurality of components, the present invention can reduce work load and time compared to the related art.

In addition, the damping panel 200 manufactured by this manufacturing method is also simple in comparison with the conventional technique in the installation method. The damping panel according to the related art requires a separate fastening and disposing process for manufacturing and installation, but the present invention is not limited to the structure in which the manufactured damping panel 200 is simply placed at the mounting position, .

Hereinafter, a floor structure in which the damping panel 200 as described above is constructed will be described with reference to FIGS. 6 to 7. FIG.

First, the floor main body has a heat insulating material 111 placed on a floor slab 110 as a foundation, a lightweight foamed concrete 112 placed thereon, a piping 115 for heating is installed thereon, and a finishing mortar 113 to cover the pipe 115 and then to install a finish material 114 such as a long plate.

In this construction procedure, the damping panel 200 is placed on the heat insulating material 111 after the heat insulating material 111 is seated, and the lightweight foamed concrete 112 is placed thereon. At this time, in order to fill the space 220a on the upper surface of the damping panel 200, the lightweight foamed concrete 112 may be installed after the sound absorbing panel material 500 is placed on the damping panel 200 have. With this configuration, even when the lightweight foamed concrete 112 is laid, the space portion 220a on the damping panel 200 can be secured by the sound absorbing plate material 500. [

When the space portion 220a is formed only between the damping panel 200 and the heat insulating material 111, the lightweight foamed concrete 112 is directly attached to the damping panel 200 without installing the sound absorbing panel material 500. [ .

Alternatively, even when the sound absorbing material is filled in the space 220a of the damping panel 200, the lightweight foamed concrete 112 may be laid directly on the damping panel 200 without the sound absorbing plate material 500. [

Here, the sound absorbing plate 500 may be formed of a plywood or a hard fiber board, and a porous sound absorbing plate may be used. The porous sound absorbing panel material has a large number of small bubbles or thin pipe-like holes formed on the surface and inside thereof, and the air in the holes is vibrated by the sound waves, and the sound energy is absorbed by the heat energy by the friction. Of course, the sound absorbing plate 500 is not limited thereto, and various sound absorbing and damping plates may be provided.

The floor structure of the present invention may further include a floor body and a side damping material 300 surrounding the rim of the damping panel 200. At this time, the side damping material 300 may have a ventilation groove 300a communicating with the space portion 220a of the damping panel 200 and the outside of the side of the covering material 114.

In this process, the damping panel 200 are absorbed by the air filled in the space portion 220a formed by the damping portion 220 of the first and second passages 200a, 200b.

At this time, the sound absorbing air in the space portion 220a of the damping panel 200 does not move to the other layer that is in contact with the bottom structure, that is, the lower layer, and the airtight groove 300a of the side damping panel 300, The noise generated in the indoor space and the impact sound impacting the floor structure from the indoor space can be prevented from being transmitted to the other floor.

The present invention may further include a racket 400 that covers a portion of the side cushioning material 300 exposed to the outside of the finishing material 114 side. At this time, the mop receptacle 400 may be formed with a connection hole 400a communicating with the outside of the finishing material 114 and the vent groove 300a.

By preventing the ventilation groove 300a of the side cushioning material 300 from being exposed to the outside space by the floor plate 400, it is possible to prevent foreign matter such as water from being easily introduced into the ventilation groove 300a have. In addition, a connection hole 400a for connecting the indoor space outside the side of the finishing material 114 to the ventilation groove 300a is formed in the baseboard 400 so that the air through the ventilation groove 300a flows into the indoor space. can do. As shown in the figure, the connection hole 400a may be formed long in a slit shape so as to be connected to the two ventilation grooves 300a. However, the connection hole 400a is not limited thereto, It is needless to say that it can be formed into various shapes in consideration of an aesthetic part.
