An elastic body is provided, and the support member is attached to the wall with the support member sandwiching the elastic member and the elastic member, thereby forming a partition by the shelf device.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In one embodiment of the present invention shown in the drawings, as shown in FIG.
It is erected on the floor (3) with a slight gap from it.

The shelf device (1) has columns (4) on the front, rear, left and right. A shelf (1a) is locked between the columns (4), (4) arranged side by side. The upper part of 4) is supported on the wall 2 by the seismic isolation support device 5. The manner of this support will be described below with reference to FIGS.

FIG. 2 shows a support (4) on the wall side of the shelf device (1).
FIG. 3 is an exploded perspective view schematically showing a structure to be supported on the wall (2) by the seismic isolation support device (5). FIG. 3 shows the structure of the seismic isolation support device (5) attached to the wall (2) and the column (4). FIG. 3 is an enlarged plan view partially sectioned.

Although the support 4 is shown as having a U-shaped cross section with an open front surface, it may be a prism having a square cross section.

Between the rear surface of the column (4) and the wall (2), a short prismatic elastic body (6) made of a hard elastic material such as polyurethane and facing in the front-back direction is provided. The front and rear surfaces are arranged in contact with the support (4) and the wall (2).
If such contact is established, a U-shaped cross section support
(4) may be arranged such that the opening side is the wall side and the elastic body (6) enters the inside of the U-shape.

The strut (4) and the elastic body (6) are gripped by a support member (7) fixed to the wall (2). The support member (7) includes a front portion (7a) covering the front surface of the support (4), and a support (7).
A side part (7b) covering the side of the elastic body (6) from the side of (4).
And a mounting part (7c) bent outward along the wall (2) from the rear end of the side part (7b), and an inward bent part inward from the upper and lower edges of both side parts (7b). (7d), and preferably formed by bending a steel plate.

In the case of this embodiment, the width of the elastic body (6) is larger than the width of the column (4).

The support member (7) increases its width diagonally from the front portion (7a) to the rear, and then reaches the side portion (7b), where the side portion (7b) is made of an elastic body (6). It is in full contact with the side surface. Upper and lower inwardly protruding portions (7d) of the side surface portion (7b) are in contact with the upper and lower surfaces of the side edge portion of the elastic body (6). Therefore, the overhanging portion (7d) secures the enclosure of the elastic body (6) while maintaining the elastic body when seismic stress is applied.
The modification of (6) is possible.

A hole (8) is formed in the mounting portion (7c), and an anchor bolt (9) inserted therethrough is screwed into an embedding fitting (10) embedded in the wall (2). By supporting members
(7) is fixed.

When the pre-assembled shelf device (1) is installed, the shelf device (1) is first carried to the side of the wall, and the supporting column on the rear side is installed.
On both sides of the upper part of (4), holes are made in the wall (2), and an embedding fitting (10) is embedded in the hole.

Next, in this position, the wall (2) and the support
The elastic member (6) is sandwiched between the supporting member (4) and the supporting member (7) is inserted from the front surface of the column (4) so as to sandwich the elastic member (6). Is screwed into the embedding fitting (10) with the anchor bolt (9) to fix the support member (7).

In the embodiment described above, the rear side of the shelf device (1) is supported by the wall (2), but the shelf device (1) is supported by the wall (2).
And the support (4) on the side of the shelf device (1)
Can be attached to the wall (2) by the seismic isolation support device (5) of the present invention, and a partition can be formed by the shelf device (1).

[0022]

According to the present invention, even if the shelf device swings greatly due to the earthquake, the rear strut is buffered by the elastic body, so that at least half of the impact force of the earthquake in the longitudinal direction of the wall is elastic. It is absorbed by the body and exerts the seismic isolation effect. Due to this seismic isolation effect, a sufficiently effective support can be achieved at the time of an earthquake even if the number of support points is small and only the upper part is used, as compared with the conventional rigid structure. Also, the support device can be simpler than in the case of a rigid structure.

According to a second aspect of the present invention, there is provided an overhang portion which projects inward in the horizontal direction from above and below both side portions of the support member which abuts on both side surfaces of the elastic body and abuts on the upper and lower surfaces of the elastic body. In this way, the elastic body is sealed, and during the earthquake, the elastic body does not fall off by any chance, and the impact force of the earthquake can be absorbed by its elastic deformation.

According to the third aspect of the present invention, the width of the hard elastic body provided between the wall and the post on the rear side of the shelf device is
When the width is larger than the width of the column, elastic deformation of the elastic body is allowed even for an earthquake input other than in the front-rear direction of the wall, and the impact force of the earthquake can be reduced.

According to a fourth aspect of the present invention, a hard elastic body and a support member are provided at least at an upper portion of a shelf device.
When attached to the column on the wall side, an effective seismic isolation support effect of the shelf device can be achieved with the minimum necessary support device.

According to a fifth aspect of the present invention, the shelf device is disposed at right angles to the wall, and a hard elastic body is disposed between the support at the side end of the shelf device and the wall. When the partition is formed by the shelf device by attaching the support to the wall with the support member and the elastic body interposed therebetween, the partition with the shelf device alone can be made strong against earthquakes.
