1 to 7, a bottom structure according to an embodiment of the present invention includes a floor slab 10, a deck plate 110 having a bent portion 111 formed in at least one direction, A damping panel 100 including a damping part 120 disposed on the bending part 111 and disposed on the top of the bottom slab 10 to form a space S; And a finishing mortar (13) placed on the upper portion of the heat insulating material (11). A finishing material 14 is provided on the top of the finishing mortar 13, such as a long plate.

The floor slab 10 is made of a reinforced concrete layer and is provided so as to separate a floor and a floor in a building. The bottom slab 10 is generally formed to have a thickness of 210 mm. Of course, the material and the thickness of the bottom slab 10 are not limited thereto, and may be provided with different materials and various thicknesses, if the strength for interlayer separation can be satisfied.

The heat insulating material 11 may be made of a material such as a functional synthetic resin or styrofoam so as to be made porous and perform a heat insulating function. The heat insulating material 11 is generally 30 mm thick. Of course, the material and the thickness of the heat insulating material 11 are not limited thereto, and any known heat insulating material capable of performing the heat insulating function can be applied.

The finishing mortar 13 is placed on the upper part of the heat insulating material 11 and is formed to have a thickness of 40 mm. When heating is required, a pipe 15 for heating is installed on the heat insulating material 11, and a finishing mortal 13 is installed to cover the pipe 15. Of course, the thickness of the finishing mortar 13 is not limited thereto, but may be various thicknesses capable of maintaining the strength to form the bottom layer.

The damping panel 100 includes a deck plate 110 in which a bending portion 111 is formed in at least one direction and a damping portion 120 provided in a plurality of bending portions 111 of the deck plate 110 .

In order to prevent the deck plate 110 from being bent in the longitudinal direction, a plurality of bent portions 111 are formed. The bending portion 111 of the deck plate 110 may be completely folded and protruded to one side as shown in FIG.

That is, the bending portion 111 increases the strength of the deck plate 110 and increases the force of supporting the layer disposed on the deck plate 110. Also, the bent portion 111 plays a role of maintaining a spacing space between the deck plate 110 and a lower layer thereof. Although the bending portion 111 is formed only in the longitudinal direction of the deck plate 110 in the drawing, the bending portion 111 may be formed in the width direction of the deck plate 110, Direction. ≪ / RTI >

The deck plate 110 may be made of a metal material, that is, a steel plate. For example, a GI-based steel sheet coated with zinc may be applied. Of course, the material of the deck plate 110 is not limited thereto, as long as strength can be maintained and manufacturing possible.

Further, when the deck plate 110 is formed of a steel plate, sufficient strength can be secured even with a thin thickness, and the thickness can be made 1 mm or less. That is, the thickness of the deck plate 110 may be 0.4 to 0.5 mm.

The damping unit 120 may be made of a vibration-proof material to reduce vibrations transmitted from the deck plate 110. For this, the damping unit 120 may be manufactured as a high-manganese vibration-damping steel containing a large amount of manganese. Such anti-vibration steel contains 15 to 20% by weight of manganese, and particularly, anti-vibration steel containing 17% by weight of manganese is excellent in dustproof performance. Of course, the material of the damping portion 100 is not limited to this, and may be manufactured using a metal or alloy steel such as aluminum, iron, magnesium, copper, stainless steel, or the like.

The damping unit 100 may be manufactured as a clip having a height of 10 to 40 mm by bending a high manganese steel sheet having a thickness of 1.5 mm.

More specifically, the damping portion 120 may be bent to have a Z-shaped cross section. In case of anti-vibration steel, vibration damping ability is very high in the inside of the structure, so vibration energy generated by external impact is converted into thermal energy from the inside of the structure, and the vibration proofing ability is excellent. And it has better dustproof performance against large load. Accordingly, the damping portion 120 may be provided in a Z-shape so that the stress can be concentrated on the bent portion 124 to more effectively attenuate the vibration. Of course, the shape of the damping portion 120 is not limited to this, and any shape capable of concentrating stress on the damping portion 120 may be provided.

The damping portion 120 may have a side surface 121 to be coupled to the deck plate 110 to be larger than the other side surface 122. One side surface 121 of the damping portion 120 has a large contact area with the deck plate 110 to receive the external force transmitted from the deck plate 110 as much as possible. The other side surface 122 is designed to minimize an area of contact with an area to be installed, thereby minimizing load transmission.

The damping portion 120 is formed with a groove portion 111 for inserting the bent portion 111 of the deck plate 110 on one side surface 121 of the damping portion 120 in order to increase the fastening force with the deck plate 110. [ (123) may be formed. One side of the damping portion 120 is in contact with the lower side of the deck plate 110 and the bent portion 111 of the deck plate 110 is inserted into the groove portion of the damping portion 120 . At this time, it is preferable that the damping part 120 is welded to the deck plate.

With this configuration, when an external force is applied to the deck plate 110, the load is concentrated by the bent portion 111 formed in the deck plate 110. Since the damping portion 120 is fastened to the bending portion 111, the load concentrated on the bending portion 111 is transmitted to the damping portion 120, so that the vibration can be more effectively reduced.

Further, the damping units 120 are provided in a plurality of damping plates 110 so as to be spaced apart from each other. More specifically, the damping portion 120 may be spaced apart from the adjacent damping portion in the range of 160 to 370 mm. In this case, the damping unit 120 may have a spring coefficient of 6 to 14 kgf / mm.

When the damping portion 120 having the spring coefficient within the above range is disposed on the deck plate 110 at intervals of 160 to 370 mm, the impact load caused by the person walking in the room can be more effectively attenuated.

4 (a) and 4 (b) are front views schematically showing a damping panel according to another embodiment of the floor structure according to the embodiment of the present invention.

The damping panel 100a according to another embodiment of the present invention is the same as the damping panel 100 and the deck plate 110 according to the embodiment of the present invention described above, The groove portion 123a differs from the damping portion 120a fastened to the groove 111 in the shape of the groove 123a.

4A, the groove portion 123a of the damping portion 120a is formed so as to penetrate deeper than the height of the bending portion 111 of the deck plate 110, So that the side surface 121a is tightly adhered to the surface of the deck plate 110.

A slit groove 112a is formed in a longitudinal direction of the bent portion 111 of the deck plate 110 and a protrusion 125a is formed in a groove portion 123a of the damping portion 120a, The protrusion 125a of the damping portion 120a may be inserted into the slit groove 112a of the first housing 110 to be fitted thereinto. Of course, the damping portion 120a may be slidably engaged with the slit grooves 112a of the deck plate 110 so as to move and change the fastening position.

With this structure, the damping portion 120a fastened to the bent portion 111 of the deck plate 110 can be easily fastened to the user's desired position, and the damping portion 120a is fastened to the deck plate 110 So that it is possible to save the working time.

4B, the groove 123b of the damping portion 120b is formed to receive only a part of the bent portion 111 of the deck plate 110, So that the side surface 121b is spaced apart from the surface of the deck plate 110.

With this configuration, the bent portion 111 of the deck plate 110 comes into line contact with the groove portion 123b of the damping portion 120b, so that the stress is concentrated in the groove portion 123b. In the case of the high-manganese-type anti-vibration steel, since the vibration damping ability against a high load is excellent, the vibration can be more effectively reduced by concentrating the stress in the groove 123b. A space between the deck plate 110 and the bottom slab 10 can be further secured by a spaced distance between the surface of the deck plate 110 and one side 121b of the damping portion 120b.

5 and 6, the damping panel 200 according to another embodiment of the present invention includes a damping portion 220 having a Z-shaped cross section, and a side surface 221 of the damping portion 220, And a deck plate 210 provided with a bent portion 211 bent to be fastened.

The bending portion 211 of the deck plate 210 is bent in a shape corresponding to one side 221 of the damping portion 220 and the side surface 221 of the damping portion 220 is bent, A side surface 221 of the damping portion 220 is inserted into the slit groove 212 formed in the bent portion 211 of the deck plate 210, .

The side surface 221 of the damping portion 220 may be slidably engaged with the slit groove 212 formed in the bent portion 211 of the deck plate 210. With this configuration, it is possible to shorten the manufacturing time by simply fitting the damping portion 220 to the deck plate 210 without welding, and it is possible to easily adjust the interval between the damping portions 220 have. Of course, the method of fastening the damping part 220 to the deck plate 210 is not limited to this, and various mechanical fastening methods may be applied.

The thickness of the damping panel 100 formed by the deck plate 110 and the damping portion 100 may be such that the deck plate 110 is formed to a thickness of 0.4-0.5 mm, Since it is manufactured to a height of ~ 40mm, it can be provided with 10.4 ~ 40.5mm.

Therefore, in the bottom structure according to the embodiment of the present invention, the bottom slab 10 is 210 mm, the damping panel 100 is 10.4 to 40.5 mm, the heat insulating material 11 is 30 mm, and the finish mortal 13 is 40 mm. The thickness is set to 290.4 to 320.5 mm.

Compared with this, the floor structure by the general wet method has a total thickness of 320 mm since the floor slab is 210 mm, the heat insulating material is 30 mm, the lightweight foamed concrete is 40 mm and the finishing mortar is 40 mm. However, in the case of the floor structure by the general wet method, since the thickness of the floor slab is increased or a separate vibration or noise preventing member is added to prevent the noise of the floor, the bottom floor structure according to the embodiment of the present invention, The thickness of the structure becomes thicker than 320 mm.

Further, when the thickness of the damping portion 120 is 35 to 40 mm, a space of 35 to 40 mm is formed between the bottom slab 10 and the deck plate 110. At least one of the wiring for communication or the wiring for power may be arranged in the space formed as described above. That is, the space for wiring formed on the ceiling may be formed on the floor to further secure the height of the ceiling of the room or lower the floor height.

7, even after the floor structure is constructed, the damping panel 100 may be provided with a space portion S formed between the floor slab 10 and the deck plate 110, A sleeve pipe 500 for communicating the space S formed by the damping panel 100 with the outer side of the finishing mortar 13 is provided so as to install or remove at least one of the wires L .

The sleeve tube 500 is provided in the form of a tube having a hollow portion 520, and a flange portion 510 protruding outward is formed.
