Abstract

PROBLEM TO BE SOLVED: To provide a base isolation supporting device for moving partition wall, capable of absorbing vibration when relative vibration occurs between a wall body and a floor due to an earthquake, and thereby avoiding damage to connection part with a sash pulley or an engaging part with a rail. SOLUTION: An elastic supporting member 6 is fixed in the lower part of a wall body 4. The upper part of a leg member 7 is elastically vertically supported by the elastic supporting member 6, and the lower part is tiltably joined to the floor face 22, and thus to form a base isolation supporting device 5. The elastic supporting member 6 has a spring receiving cylinder 8, a spring 9 in its inside, and a base nut 10 in the lower part. The base nut 10 cannot be rotated in the spring receiving cylinder 8, but can move vertically. The leg member 7 has a supporting seal 11 joined on the floor face 22, and a screw bar 12 connected to the supporting seat tiltably and rotalably. The screw bar 11 is screwed into the base nut 10 up to an intermediate part, and the upper part of the screw bar extends upward in the spring receiving cylinder 8. Vertical relative vibration between the wall body 4 and the floor 22 is absorbed by expansion and contraction of the spring 9, and horizontal relative vibration is absorbed by tilting of the screw bar 12 in relation to the supporting seat 11.

And the upper part of the leg member 7 is elastically supported in the vertical direction by the elastic support member 6, and the lower part is the floor surface 22 of the building.
To form a seismic isolation support device 5 for a movable partition wall. The elastic support member 6 includes a spring receiving cylinder 8 fixed in the wall body 4, a spring 9 held in the spring receiving cylinder 8, and a vertical movement in the spring receiving cylinder 8 positioned below the spring 9. The base member 10 is freely and non-rotatably held. The leg member 7 has a support seat 11 joined on a floor surface 22 and a lower end tiltably and rotatable with respect to the support seat 11 at the lower end. Base nut 10
And a screw rod 12 whose upper portion extends upward in the spring receiving cylinder 8. The relative vibration in the vertical direction between the wall body 4 and the floor 22 is absorbed by expansion and contraction of the spring 9, and The relative vibration is absorbed by the inclination of the screw rod 12 with respect to the support seat 11.

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a sectional view of a moving partition wall, and FIG. 2 is an enlarged sectional view of a portion of a seismic isolation support device.

In FIG. 1, a movable partition wall 1 is provided with a wall 4 which is movable by rolling a suspension car 3 along a rail 2 laid on a ceiling 21 of a building. The wall body 4 is supported on a floor 22 by a base isolation device 5 at a desired position.

The seismic isolation support device 5 has an elastic support member 6 fixed in the lower portion of the wall body 4 and an upper portion elastically supported by the elastic support member in the up-down direction, and a lower portion is freely tiltable on the floor of the building. And a leg member 7 to be joined to the base member.

The elastic support member 6 includes a spring receiving cylinder 8 fixed in the wall body 4, a spring 9 held in the spring receiving cylinder 8, and a spring 9 positioned below the spring 9 and in the spring receiving cylinder 8. A base nut 10 that is vertically movable and non-rotatably held.

The spring receiving tube 8 has a rectangular tube shape, has a spring receiving member 13 at the upper end, and has an inward flange 14 at the lower end.
And is open to the lower end side of the wall 4. The upper end of the spring 9 is locked by the spring receiving member 13, and the lower end is locked by the base nut 10. The base nut 10 is rectangular in a plan view, receives the lower end of the spring 9 on the upper surface, and the lower surface is in contact with the inward flange 14. The base nut 10 is integrally provided with a screw cylinder 10a having a screw hole continuous with the base nut 10.

The leg member 7 includes a support seat 11 joined on a floor surface 22 and a screw rod 12 at the lower end of which is connected to the support seat 11 so as to be tiltable and rotatable. The screw rod 12 has a ball portion 15 at the lower end, is screwed into the base nut 10 in the middle, and the upper portion extends upward in the spring receiving tube 8. The support seat 11 is provided at the lower part with a joint 1 to be joined to the floor surface.
6 and a ball socket 17 at the top for receiving the ball 15 of the threaded rod. In addition, the screw rod 12 has a cover portion 18 at a lower portion that covers and conceals a connecting portion between the ball portion 15 and the ball socket 17 from outside. This cover part 18
Is provided with a tool engaging portion 19 for engaging a tool for rotating the screw rod 12 around the axis.

[0011] When the hanging wheel 3 is rolled along the rail 2 to move the wall 4 and is brought to a desired position,
A tool is hung on the tool engaging portion 19 of the screw rod 12 to
Is rotated so that it protrudes downward with respect to the base nut 10. If the rotation of the screw rod 12 is continued even after the support seat 11 abuts on the floor surface 22, the base nut 1
0 rises in the spring receiving cylinder 8 to compress the spring 9,
Is transmitted to the support seat 11 through the screw rod 12. Therefore, the wall body 4 is supported on the floor surface 22 by the leg members 7 with the elastic force of the spring 9. In this state, if a relative vibration in the vertical direction occurs between the wall 4 and the floor 22 due to an earthquake or the like, the spring 9 expands and contracts to absorb the vibration. The horizontal relative vibration is absorbed by the inclination of the screw rod 12 with respect to the support seat 11. Therefore, no excessive stress is applied to each part, and damage can be avoided.

[0012]

As described above, according to the present invention, the elastic support member 6 is fixed in the lower portion of the wall 4, and the upper portion of the leg member 7 is elastically supported by the elastic support member 6 in the vertical direction. At the same time, the lower part is tiltably joined to the floor surface 22 of the building to form the seismic isolation support device 5 for the movable partition wall. Elastic support member 6
A spring receiving cylinder 8 fixed in the wall 4, a spring 9 held in the spring receiving cylinder 8, and a vertically movable and non-rotatable member located below the spring 9 in the spring receiving cylinder 8. And a base nut 10 held so as to be capable of being held. The leg member 7 has a support seat 11 joined to a floor surface 22 and a lower end tiltably and rotatably connected to the support seat 11 at a lower end. A screw rod 12 which is screwed into the base nut 10 and has an upper part extending upward in the spring receiving cylinder 8 is provided. The relative vibration in the vertical direction between the wall body 4 and the floor 22 is absorbed by expansion and contraction of the spring 9, Since the relative vibration in the horizontal direction is absorbed by the inclination of the screw rod 12 with respect to the support seat 11, there is an effect that it is possible to avoid breakage of the connecting portion with the suspension vehicle and the engaging portion with the rail.
