Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an upper structure that is isolated from the foundation in a horizontal direction by a seismic isolation device interposed between the foundation and the upper structure so that the upper structure is not shaken by wind pressure in the event of a typhoon or the like. The present invention relates to a fixing device for temporarily fixing with respect to the horizontal direction.
[0002]
[Problems to be solved by the invention]
As a seismic isolation device that is interposed between the foundation and the upper structure, protects the upper structure from earthquakes, and makes the upper structure a seismic isolation structure, laminated rubber composed of laminated rubber plates and steel plates, this lamination There are various types, such as laminated rubber with lead plugs with lead struts on rubber, sliding bearings using sliding, and rolling bearings using rolling rollers.
[0003]
In any of the above seismic isolation devices, the rigidity in the horizontal direction, which is the vibration direction, is lowered, and the natural vibration period in the horizontal direction of the vibration system including the superstructure is made longer than the horizontal vibration period of the earthquake. Therefore, the vibration of the superstructure due to the earthquake is suppressed.
[0004]
By the way, since the seismic isolation device with low horizontal rigidity responds even with a small horizontal force, the superstructure supported by the seismic isolation is shaken in the horizontal direction even if a little wind pressure is applied. When the structure is an apartment house such as a condominium, an office building, a detached house, or the like, there is a risk of causing extremely great discomfort to residents due to rolling due to wind pressure.
[0005]
In response to the above-mentioned problems related to unpleasant rolls of the superstructure due to wind, various seismic isolation and windproof structures have been proposed that include a fixing device that fixes the superstructure to the ground in strong winds. In many cases, the structural fixing device is configured to insert a lock pin provided on the ground side into a hole provided on the upper structure side to fix the upper structure to the ground in the horizontal direction.
[0006]
By the way, with the proposed fixing device, when fixing an upper structure shifted in the horizontal direction from the original position (origin position) to the ground, the upper structure is moved in the horizontal direction once with a jack or the like. Since the lock pin is inserted into the hole after returning to the origin position, the fixing work is extremely complicated.
[0007]
Even if a seismic isolation device having a function to return the upper structure to the origin position (origin return function) is used, the upper structure may be displaced horizontally from the origin position. Even in a seismic structure, the fixing work using the lock pin by the proposed fixing device is extremely complicated.
[0008]
The present invention has been made in view of the above points, and the object of the present invention is to prevent unpleasant rolling of the upper structure due to wind and to cause the upper structure to shift horizontally from the origin position. However, the object is to provide a seismic isolation structure fixing device that can perform fixing work very easily.

In the fixing device 4, when the wind becomes weak after passing through a typhoon or the like, the wire 121 is pulled manually or automatically, and the engagement member 100 is pulled in a direction in which one end having the conical surface 106 of the main body 107 is retracted into the through hole 105. 1 and the engagement pin 60 held at the recess 14 is dropped from the recess 14 when the one end having the conical surface 106 of the main body 107 is released from the engagement recess 60, as shown in FIG. In this way, the base member 1 in the horizontal direction H of the detached house 2 via the connecting pin 10 is released from the foundation 1 and then fixed to the ground. It will be able to be demonstrated as it is.
[0063]
By the way, according to the fixing device 4, since the movable stand 6 is raised, the inclined projecting surface 7 can be fitted to the inclined concave surface 13 and the detached house 2 can be moved in the horizontal direction H. The positional deviation from the origin position of the house 2 can be corrected, and at the same time, the connecting pin 10 supported by the pin support 11 is recessed from the pin housing 8 whose rise is blocked by the blocking surface 16 when the movable table 6 is lifted. 14, the detached house 2 can be fixed with respect to the foundation 1 in the horizontal direction H. Therefore, even when the detached house 2 is displaced in the horizontal direction H from the origin position, the movable table 6 can be fixed. The home position of the detached house 2 and the fixing with the connecting pin 10 can be performed by one operation of raising, so that the fixing work can be performed very easily, and unpleasant rolling of the detached house 2 due to the wind can be prevented. Can be prevented.
[0064]
Moreover, according to the fixing device 4, since each of the inclined projecting surface 7 and the inclined concave surface 13 has the truncated conical surface 34 and the truncated conical surface 92, the space between the detached house 2 and the foundation 1 is narrow. Further, the pin accommodating body 8 is guided by the movable base 6 on the cylindrical outer peripheral surface 42 and the connecting pin 10 moves the vertical movement thereof in the cylindrical inner peripheral surface 44 of the pin accommodating body 8. Therefore, there is no backlash between the pin accommodating body 8 and the movable base 6 and between the connecting pin 10 and the pin accommodating body 8, so that the connecting pin 10 can always be held in a normal position. In addition, since the connecting pin 10 is supported via the movable piece 63 and the coil spring 64, when the movable base 6 is raised, the connecting pin 10 is connected to the recess 14 by fitting the inclined projecting surface 7 to the inclined concave surface 13. Connected when alignment with pin 10 is not complete Forcibly pressing the pin 10 against the pin receiving member 15 on the detached house 2 side can be prevented by the elastic contraction of the coil spring 64, so that the pin receiving member 15 on the detached house 2 side by the connecting pin 10 can be prevented. In addition, damage and the like can be eliminated, and in addition, the restricting member 65 and the restricting means 85 can prevent the pin housing 8 from falling off the movable base 6, and the engagement generating means 101 causes the engaging member 100 to move in the horizontal direction H. Since the coil spring 112 that elastically biases in one direction is provided, the engagement member 100 is driven in the horizontal direction H in particular in the horizontal direction H by eliminating the pull of the wire 121 in the disengagement means 102. Can be moved automatically without the need for
