DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-vibration floor structure for a prefabricated house or the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 5 and 6, a floor support 41 is fixed to a floor beam 40 with a fastener (not shown). Panels 42, 4
3 was placed and fixed with bolts and nuts 44. However, in the floor structures of FIGS. 5 and 6, the floor panels 42, 4
3 is directly mounted and fixed on the floor fitting 41, so that when a child jumps, a loud impact sound is generated, and this impulsive sound is transmitted directly to the lower floor, causing a great deal of trouble to residents on the lower floor. was there.

Accordingly, as shown in FIGS. 7 and 8, between a floor support 45 fixed to a floor beam 40 and floor panels 42 and 43, a liquid ring damper 46 for absorbing an impact is interposed to provide an impact. A vibration-absorbing floor structure that absorbs sound has been proposed.

[0004]

However, in the vibration isolating floor structure shown in FIGS. 7 and 8, adjacent floor panels 42, 43 are provided.
Are individually attached to the floor beams 40 via the liquid ring dampers 46, so that the floor panels 42, 43 individually move up and down in response to an impact individually acting on the floor panels 42, 43. For this reason, a step is generated between the adjacent floor panels 42 and 43, and as a result, there is a problem that a crack or a crack is generated in a floor finishing material (not shown) laid on the entire floor panel.

An object of the present invention is to provide an anti-vibration floor structure in which there is no step between adjacent floor panels.

[0006]

According to a first aspect of the present invention, there is provided an anti-vibration floor structure, wherein panel frames of adjacent floor panels are separately attached to a building frame at predetermined intervals via a liquid ring damper. with placing a buffer plate for absorbing a level difference caused by vertical movement of the floor panels between faceplate of the floor panel both were bonded to a panel frame, both side edges of the buffer plate, both
Are each supported by a panel frame of the floor panel .

According to the vibration isolating floor structure of the first aspect, since the cushioning plate is erected between the floor panels provided at a fixed interval, there is no step between the floor panels, and the floor panel is mounted on the entire floor panel. Cracks and cracks do not occur in the laid floor finishing material. In addition, both side edges of the buffer board are panel frames of both floor panels
Easy mounting work of the buffer plate because it can be placed and fixed on
It is. According to a second aspect of the present invention, in the first aspect, the cushioning plate is a plate having substantially the same thickness as the surface panel of the floor panel, and is attached between the surface panels of the floor panel. Is what you do.

According to the vibration isolating floor structure of the second aspect, in addition to the function of the first aspect, the buffer plate is formed of a plate having substantially the same thickness as the surface plate of the floor panel, and the connection portion of the floor panel is formed. fit is good, Ru excellent in workability.

Is the I-shaped steel floor beam joint (building body), 14 and 15 are floor supports attached to both sides of the floor beam joint 13, and 18 is the floor beam 1
It is a floor fitting attached to the side of No. 2. Floor support 14,1
5, 18 are formed in the same shape, and the vertical pieces 14a, 15a, 18a and the horizontal pieces 14b, 15b, 1 respectively.
8c, reinforcing pieces 14c, 15c, 1
8c is welded, and a pair of upper and lower bolt insertion holes (not shown) and horizontal pieces 14b, 1 are formed in the vertical pieces 14a, 15a, 18a.
Bolt insertion holes (not shown) are formed substantially at the centers of 5b and 18b. The floor fittings 14 and 15 are the floor beam joint members 13.
The vertical pieces 14a and 15a are arranged so as to face both side surfaces of the floor member, and are simultaneously fixed to the floor beam joint member 13 with bolts and nuts 16. In addition, the floor support 18 is provided with a vertical piece 18 on the side of the floor beam 12.
a is fixed to the floor beam 12 with bolts and nuts 19.

Further, the horizontal pieces 1 of the floor fittings 14, 15, 18
A liquid ring damper 17 having the same configuration is placed on each of 4b, 15b and 18b. As shown in FIG. 4, the liquid ring damper 17 includes a main fluid chamber 3 having a cavity in a rubber mount 30.
1, an auxiliary fluid chamber 33 in which a diaphragm 32 is stretched, and an orifice 34 connecting the two chambers 31, 33.
A viscous fluid is sealed in 1 and 33. Bolts 35 and 36 project from the upper and lower ends. The liquid ring damper 17 connects the bolt 36 at the lower end with the floor fittings 14, 15, 18.
Of the floor panels 10, 11a of the floor panels 10, 11 are fixed by nuts.

Further, in FIG. 1, at the joint between adjacent floor panels 10 and 11, it is attached to panel frames 10a and 11a.
Surface plates 10b and 11b of both floor panels 10 and 11
A buffer plate 20 is installed between them. The buffer plate 20 is a long plate extending along the joint, and is formed to have substantially the same thickness as the surface plates 10b and 11b of the floor panels 10 and 11. And
Panel frames 10a, 11 which protrude both side edges of the buffer plate 20 from the surface plates 10b, 11b of both floor panels 10, 11.
a, and the panel frame 10a,
11a. Note that a finishing material (not shown) is laid on both floor panels 10 and 11 and the entire buffer plate 20.

Next, the operation will be described. Floor panel 1
Liquid seal damper 17 due to children jumping on 0, 11
, The rubber mount 30 is compressed and deformed up and down, and the liquid filled in the main fluid chamber 31 moves up and down the orifice 34, and the impact absorbs the shock. When the floor panels 10 and 11 move up and down independently, a height difference occurs between the floor panels 10 and 11, but the buffer plate 20 is inclined and both side edges are smoothly continuous with the floor panels 10 and 11. Absorbs steps.

According to the vibration isolating floor structure constructed as described above, since the cushioning plate 20 is provided between the floor panels 10 and 11 provided at a predetermined interval, a step may be generated between the floor panels 10 and 11. Also, no cracks or cracks occur in the floor finishing material laid on the entire floor panel. Further, the buffer plate 20 is formed of a plate body having substantially the same thickness as the surface plates 10b and 11b of the floor panels 10 and 11, so that the connection portion of the floor panels 10 and 11 is well fitted and the workability is excellent.

Further, both side edges of the buffer plate 20 are supported by panel frames 10a, 11a of both floor panels 10, 11, respectively, and the buffer plate 20 is substantially the same as the surface plates 10b, 11b of the floor panels 10, 11. Since the plates have the same thickness, there is no step between the surface plates 10b and 11b of the floor panels 10 and 11 and the buffer plate 20. Further, since both side edges of the buffer plate 20 can be placed and fixed on the panel frames 10a and 11a of both floor panels 10 and 11, the mounting operation of the buffer plate 20 is easy.

[0016]

According to the vibration isolating floor structure of the first aspect, the cushioning plates are erected between the floor panels provided at regular intervals, so that there is no step between the floor panels, so that the entire floor panel can be formed. Cracks and cracks do not occur in the floor finishing material laid on top. In addition, both side edges of the buffer board are panel frames of both floor panels
Easy mounting work of the buffer plate because it can be placed and fixed on
It is. According to a second aspect of the present invention, in the first aspect, the cushioning plate is a plate having substantially the same thickness as the surface panel of the floor panel, and is attached between the surface panels of the floor panel. Is what you do.
