DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to embodiments and drawings. The drawings used here are FIGS. 1 to 4. FIG. 1 is a perspective view showing an embodiment of the present invention. FIG. 2 is a vertical sectional view showing an embodiment of the present invention, and has the same configuration as the embodiment shown in FIG. FIG. 3 is a perspective view showing a second embodiment of the present invention. FIG. 4 is a vertical sectional view showing a third embodiment of the present invention.

First, a first embodiment of the present invention will be described with reference to FIGS. (Overall overview) The building shown in FIG. 1 and FIG.
A beam 50 fixed horizontally to the pillar 40 is provided. The floor member 20 is suspended from the beam 50 using the suspension member 10. And it is an earthquake-resistant structure in which an elastic member 30 for absorbing and dispersing shaking caused by an earthquake is located between the floor member 20 and the suspension member 10. (Suspension Member) The suspension member 10 is a member for suspending the floor member 20.

The suspending member 10 has a supporting portion 11 for supporting a lower portion of the floor member 20 and a connecting portion 12 projecting upward from the supporting portion 11 and fixing to the beam 50. In the present embodiment, the support portion 11 is formed of a plate-like member. This makes it easier to position the floor member 20 on the elastic member 30 and on the elastic member 30. Further, the connecting portion 12 is formed by a columnar member, but may be a square member, a chain member, or the like as long as the member can connect and fix the supporting portion 11 to the beam 50. (Floor member) The floor member 20 is formed as a box-shaped body 21 that opens upward. Then, the internal space of the box-shaped body 21 is defined as an indoor space. Specifically, in a state where the box-shaped body 21 is attached, the side surface of the box-shaped body 21 forms a wall of the room, and the bottom surface forms a member forming the floor of the room. Also, box-shaped body
The bottom surface of 21 is provided with a hole 23 for penetrating the connecting portion 12 of the suspension member 10.

A pedestal 22 for stably mounting the box-shaped body 21 on the upper surface of the elastic member 30 is provided below the box-shaped body 21.
Is provided. The pedestal 22 forms a member that is less likely to be elastically deformed than the elastic member 30. In the present embodiment, pedestal 22 is formed of a single iron plate. And the pedestal
22 has a hole that can penetrate the connecting portion 12 of the suspension member 10. A hole provided in the pedestal 22 and a hole 23 provided in the box-shaped body 21
If possible, the connecting part 12 should be box-shaped
In order not to touch the connecting portion 12, the connecting portion 12 is formed to have a larger cross-sectional shape.

When the pedestal 22 is formed of a plurality of plate-like members and does not hinder the fixing of the connecting portion 12 to the beam 50, there is no need for a hole for penetrating the connecting portion 12. (Elastic Member) The elastic member 30 is formed of a rubber plate.
The rubber plate has a hole through which the connecting portion 12 of the suspending member 10 passes.
33 is provided. The hole 33 is formed to have a larger cross-sectional shape than the cross-sectional shape of the connecting portion 12 in order to prevent the connecting portion 12 from touching the elastic member 30 as much as possible even if the hole 33 is shaken by an earthquake. Note that the elastic member 30 may use a block-like rubber having a thick rubber plate. (Building method) First, the elastic member 30 is placed on the upper portion of the support portion 11 through the connection portion 12 of the hanging member 10 through the hole 33 of the elastic member 30.

Next, the floor member 20 is placed on the elastic member 30 through the connecting portion 12 of the hanging member 10 through the hole 23 of the floor member 20. Next, the upper part of the connecting portion 12 of the suspension member 10 is fixed to the beam 50. The operation of the present embodiment will be described. Pillar 40 or beam 50 due to an earthquake or the like, and hanging member 10 fixed to the beam 50
When swinging, the hanging member 10 and the box-shaped body 21 are not fixed, so that the swing is transmitted to the box-shaped body 21 via the elastic member 30. Therefore, the elastic member 30 elastically deforms, thereby absorbing and dispersing the kinetic energy due to the shaking, and
Shaking transmitted to 21 can be reduced.

When the box-shaped member 21 is attached, an indoor space is formed. For this reason, it is possible to save the trouble of erecting the wall after forming the floor surface as in the related art. As a result, construction work on site can be facilitated. In addition, since the pedestal 22 is provided below the box-shaped body 21, the box-shaped body 21 can be easily mounted on the upper surface of the elastic member 30. Therefore, work on site can be facilitated.

Next, a second embodiment will be described with reference to FIG. (Overall Overview) The second embodiment differs from the first embodiment in that the floor member 20 is formed of a surface material. Therefore, after installing the floor member 20, the wall is erected. Other configurations are the same as those of the first embodiment, and therefore, the same components will be denoted by the same reference characters and description thereof will be omitted.

The operation of the embodiment will be described. Floor member 20
Is formed as a face material, the floor member 20 can be formed to be lighter than when the floor member 20 is formed as a box-shaped body 21. Therefore, the work of connecting and fixing the connecting portion 12 of the suspension member 10 to the beam 50 can be easily performed. Next, a third embodiment will be described with reference to FIG. (Overall Overview) The third embodiment is different from the first embodiment in that the building of FIG. 4 has a substantially cylindrical pillar 40 and is fixed to the pillar 40, And a sleeve member 51 having a sleeve portion 52 protruding in the horizontal direction from the sleeve member 51, and the hanging member 10 is connected and fixed to the sleeve member 51.

Other configurations are the same as those of the first embodiment, and therefore, the same components are denoted by the same reference numerals and description thereof will be omitted. (Sleeve member) The sleeve member 51 is substantially donut-shaped, and has a main body, a sleeve 52 protruding horizontally from the main body, and capable of fixing the upper part of the connecting portion 12 of the suspension member 10, and a cylindrical member. A column that can penetrate the column 40 has a column hole. Although not shown, the sleeve member 51 includes two sleeve portions 52. Thereby, the suspension member
10 are connected to the sleeve 52 one by one, and the two suspension members 10 can be connected to the sleeve member 51.

Although the sleeve member 51 is used in the present embodiment, the sleeve member 51 projects horizontally from the column 40 itself, and the hanging member
The ten connecting portions 12 may be formed with sleeve portions that can be fixed. In this case, the sleeve member 51 is not required. The operation of the present embodiment will be described. The sleeve member 51 can be formed smaller than the beam 50. Therefore, construction work on site can be facilitated. Also, when forming the beam 50, a joint member for connecting the beam 50 to the column 40, a cross member,
Although fastening means such as bolts are required, the use of the sleeve member 51 can reduce the number of parts.
