Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seismic isolation structure which movably supports a structure on a foundation by means of a linear motion supporting device, and more particularly to a seismic isolation structure provided with a device for suppressing the movement thereof.

[0002]

2. Description of the Related Art In general, a support device for a base-isolated structure is usually composed of laminated rubber, friction slides and the like. However, this type of support device requires a relatively high hardness to support heavy structures. Therefore, the natural period of the structure could not be set to a sufficiently long period necessary for seismic isolation, and the desired seismic isolation effect was not achieved.

Therefore, a linear motion support device has been proposed as a seismic isolation means to replace the laminated rubber or the like (Japanese Patent Laid-Open No. 8-24).
No. 0033).

That is, referring to FIGS. 7 and 8, the linear motion supporting device 10 includes rolling rails 16 and 18 fixed to a foundation 12 and a structure 14 via a spherical or cylindrical rolling element 20. The blocks 22 and 24 are rotatably connected to the blocks 22 and 24 and are orthogonal to each other.
It is configured by combining four. Such a linear motion support device 10
By using, it is possible to freely allow the mutual movement of the structure 14 with respect to the foundation 12 in a state where friction is as low as possible, and thus it is possible to effectively block the vibration transmission from the foundation 12.

[0005]

As described above, the seismic isolation structure supported by the linear motion supporting device is allowed to freely move with respect to the foundation of the structure. Such a small and lightweight structure may move due to strong wind pressure such as a typhoon, or the structure may move due to residual displacement due to uneven settlement of the ground such as during a large earthquake. Further, in general, the seismic isolation structure is a mechanism for releasing the fixed portion so that the seismic isolation device works only during an earthquake, so there is a possibility that the seismic isolation device may not operate when necessary due to deterioration of the fixed portion for many years.
Further, in the conventional linear motion supporting seismic isolation structure, although the movement restoring device is used, no measures have been taken to prevent the movement itself in advance.

Therefore, an object of the present invention is to prevent the structure from moving due to wind pressure and to effectively prevent the structure from moving due to residual displacement due to uneven subsidence of the ground, and to reliably prevent an earthquake. It is to provide a seismic isolation structure that operates.

[0007]

In order to achieve the above object, the present invention provides a seismic isolation structure having a seismic isolation device comprising a linear motion supporting device for movably supporting a structure on a foundation. , By providing a movement restraint device between the foundation and the structure that can manually switch the operation and cancellation of the restraint function that restrains the relative movement of the structure with respect to the foundation, this movement restraint device is restrained during strong winds. This function prevents the seismic isolation structure from moving by completely fixing the seismic isolation structure to the foundation, and the linear motion support device is in a fixed state where it cannot exert its seismic isolation function. in the by releasing the inhibit feature, seismic isolation structure is not fixed to the underlying linear motion support apparatus base isolation structure to seismic isolation ready to exert its seismic isolation function, according to claim 1-9 Features of

The structure 14 is fixed to the foundation 12 by being expanded by the pressurizing means, and the fluid pressure is released to be in the seismic isolation state.

An embodiment of the tension mooring system of the movement restraining device 26 according to the present invention will be described below with reference to FIGS. In addition, in these examples, basically, the structure 14 is moored to the foundation 12 with a required tension to be in a fixed state, and the mooring is released to be in a seismic isolated state.

That is, in the movement restraining device 26 shown in FIG. 2A, mooring arms 61 and 62 are projectingly provided on the foundation 12 and the structure 14, respectively, and these mooring arms 61 and 62 are provided.
The turnbuckle 63 is suspended between the two, and is manually tightened by screwing to tighten and fix it in a fixed state, and is loosened to a seismic isolated state. The movement restraining device 26 shown in FIG. 2B is composed of a wire assembly 64 mounted between the foundation 12 and the structure 14, and the wire assembly 64 is

Furthermore, in the movement restraining device 26 shown in FIG. 2C, the winding wire 68 is mounted between the foundation 12 and the structure 14, and the drive unit 70 fixed to the foundation 12 is driven to move the winding wire 68. Rotating tension makes the structure 14 the foundation 1
It is configured to be fixed to 2 and to be seismically isolated by loosening.

Next, FIGS. 3 (a) and 3 (b) show an embodiment of the movement restraining device 26 of the crimping type. In this example, basically, the structure 14 is crimped to the foundation 12 with a required pressing force to be in a fixed state, and the crimping is released to be in a seismic isolated state.

That is, in the movement restraining device 26 shown in FIG. 3A, the crimping edges 71 and 72 are provided between the foundation 12 and the structure 14, respectively, and the crimping edges 71 and 7 are provided.
2 and 4 are sandwiched by a crimping metal fitting 74 with a spacer 73 interposed therebetween, and a screw 75 is tightened to crimp the structure 14 to the foundation 12 to a fixed state, and the tightening is released to a seismic isolated state. Further, in the movement restraint device 26 shown in FIG.

Further, FIGS. 4A to 4C show an embodiment of the horizontal support system of the movement restraining device 26 according to the present invention. It should be noted that these embodiments are basically configured so that the structure 14 is restrained from moving with respect to the foundation 12 by a required horizontal pressing force, and the structure 14 is pressed to be in a fixed state and released. A quake occurs.

That is, in the movement restraining device 26 shown in FIG. 4A, a swing lever 79 pivotally attached to the bottom of the structure 14 at a pivot 78 and a piston connected to one end of the swing lever 79. When the swing lever 79 is swung clockwise, the piston 80 horizontally moves toward the stopper 82 provided on the foundation 12 and the piston head 84.
However, by pressing the stopper 82, the structure 14 is fixed to the foundation 12. Then, when the swing lever 79 is swung counterclockwise, the swing lever 79 is released and the seismic isolation state is set.

The movement restraining device 26 shown in FIG.
Is provided with a pressure bag 90 between the projecting edge 86 of the foundation 12 and the projecting edge 88 of the structure 14, and the pressure fluid supply source 9 is provided therein.
A pressure fluid is supplied from 2 through a check valve 94 to inflate and press the pressure bag 90. Pressure is applied to the pressure bag 90 to bring it into a fixed state, and when the pressure is removed, it becomes a seismic isolation state. A compressed air may be supplied to the pressure bag by using a compressor as a pressure fluid supply source.

Furthermore, the movement restraining device 2 shown in FIG.
6, the cylinder device 96 attached to the bottom surface of the structure 14 via the relief pins 97, 97 is urged by the drive unit 95 to press the cylinder head 98 against the restraining wall 100 of the foundation 12. By crimping it becomes a fixed state, and by releasing the crimp it becomes a seismic isolation state. Relief pin 9
7 and 97 are made of low-yield metals such as lead and tin, and low-yield alloys containing these. If a large earthquake occurs when the movement restraining device 26 is in a fixed state, the relief pins 97,
Reference numeral 97 is configured so that the seismic isolation state is instantly obtained by breaking and releasing the movement restraint. Since the release pin thus breaks, the cylinder device 96 does not break, and when the movement restraining device 26 is repaired, it can be repaired simply by replacing the relief pin. In addition to the above examples, the relief pin may be made of a resin pin, a silicic acid compound such as glass, or the like, as long as it is broken when a force of a predetermined value or more is applied during a large earthquake. The predetermined value here is set according to the scale, structure, etc. of the structure,
A large value is set for buildings and the like, and a small value is set for wooden structures and the like. In addition to the above-mentioned relief pin, a relief bolt, a relief plug or the like can be used as the relief means.

Next, the movement restraining device 26 shown in FIG.
Is a pair of cylinder devices 108, 109 on the bottom surface of the structure.
Attached to the cylinder head 11 of these cylinder devices.
0 and 111 are raised parts 112 and 1 of the foundation 12 which face each other.
13 are in contact with each other via linear roller bearings 114 and 115. The solenoid switching valve 1
16 is connected by a pipe 117 as a flow path,
The hydraulic oil with a preload of 1 to ² kg / cm ² is injected into the cylinder chamber and the pipe. Linear roller bearing 1
By interposing 14 and 115, it is possible to prevent the destruction of the cylinder devices 108 and 109 when pressure is applied in a direction orthogonal to the axial direction of the cylinder device.

In this embodiment, normally, the electromagnetic switching valve 116 is left in the seismic isolated state, and the cylinder head presses the foundation 12 by the preload of the hydraulic oil. In this case, if an earthquake occurs, the hydraulic oil can flow freely, so that the seismic isolation function works and the viscous resistance of the hydraulic oil functions as a damping device. When the electromagnetic switching valve 116 is closed in a strong wind, the flow of the hydraulic oil is shut off, so that the cylinder heads 110 and 111 of the cylinder devices 108 and 109 keep the fixed state while pressing the foundation 12 and the movement restraining device. Function as. The electromagnetic switching valve may be changed to a manual switching valve.

The movement restraining device 26 shown in FIG. 5B shows an example in which the piston rod is extended in both directions of the cylinder 118 to press the cylinder heads 110 and 111 against the foundation 12, and the other reference numerals are the same. Since it is substantially the same as the example of 5, the description is omitted. In this example, only one cylinder is required, which has the effect of simplifying the configuration.

As described above, according to the seismic isolation structure of the present invention, the movement restraining device has the maximum displacement of the structure due to the wind speed, the wind load or the like, or the residual displacement due to the differential settlement of the ground after the earthquake, etc. It is possible to prevent the structure from moving due to the unstable condition of. In addition, since the structure is always in the seismic isolation state in which it is supported by the linear motion supporting device with respect to the foundation, it is possible to reliably prevent a large damage to the structure due to an earthquake. Further, since the structure is fixed by the movement restraining device under the unstable condition, it is possible to prevent the structure from moving due to wind pressure or the like and accidental disaster caused thereby.

Although the above embodiment has been described with respect to the manual system, the movement restraining device of the present invention may be configured to be automatically operated by a sensor and / or remotely operated.

That is, FIG. 6A is the same as FIG.
The embodiment according to (a) is modified from a manual method to a configuration of automatic operation and / or remote operation by a sensor, and mechanically driving a pin 32 driven into the sand 30 of the chamber 28. Means 102 are provided,
The driving means 102 is automatically operated and / or
Alternatively, a sensor 106 such as a wind speed sensor or an earthquake sensor is connected via the remote control circuit 104. Therefore, according to this configuration, for example, the wind speed is 45 m / s and the wind load is 1
When an unstable condition occurs such that the maximum displacement of the structure due to wind is 20 cm and the residual displacement after the earthquake reaches 3 cm, the pin 32 automatically moves to the sand 3 through the driving means 102.
It is driven into 0 and becomes a fixed state, and the restraint of the movement of the structure 14 due to the wind pressure or the restraint of the structure due to the residual displacement such as an earthquake is achieved by automatic operation or remote operation.

FIG. 6B shows another embodiment of automatic operation and / or remote operation. In the figure, four cylinders 120, 122, 124, 126 are mounted inside the foundation 12 on the bottom surface of a structure (not shown). The cylinders 120, 122 abut opposite sides of the foundation 12, and the cylinders 124, 126 abut other opposing sides of the foundation 12. The cylinders 120, 122, 124, 126 are connected to a hydraulic pump 128 by a pipe 130.
The hydraulic pump 128 is operated by a manual switch 132 and is operated by a wind speed sensor 134 when a predetermined wind speed is exceeded. Further, the hydraulic pump 128 is configured to be released by the seismic sensor 136 when the seismic sensor 136 exceeds a predetermined seismic level to be in a seismic isolated state.

In this embodiment, for example, the hydraulic switch 12 is turned on by turning on the manual switch 132 when the wind is strong.
The structure can be fixed to the foundation 12 by a cylinder by operating 8 or turned off to bring the structure from the foundation 12 into a free state, that is, a seismic isolated state. Further, when the wind speed exceeds a predetermined value by the wind speed sensor 134, the hydraulic pump 128 is operated to fix the structure to the foundation 12, or when the wind is stopped, the hydraulic pump 128 is stopped and the structure is free from the foundation 12. That is, it can be in a seismic isolated state. Furthermore, for example, the structure is the basis 1
When the seismic sensor 136 detects the initial micromotion due to the P wave in the fixed state with respect to 2, the hydraulic pump is instantaneously stopped to make the structure free of the foundation 12, that is, the seismic isolated state, The damage of can be minimized. Also in this embodiment the cylinder can be used as a damping device. The seismic sensor is not limited to the one that detects P waves.

Thus, the seismic isolation structure of the present invention is usually
Since the structure is kept free of the foundation, that is, seismically isolated, the seismic isolation function works reliably during an earthquake, and damage to the structure can be prevented. In addition, since the structure is fixed to the foundation by a movement restraint device in the event of strong wind,
It is possible to prevent damage due to movement of the structure. Further, since the hydraulic pump is not operated except when the wind is strong, the power consumption can be reduced.

[0059]

As described above, the seismic isolation structure according to the present invention is provided with a device for restraining the movement of a structure that is movably supported by the linear motion supporting device. Since it is configured, it is possible to effectively prevent movement of the structure due to wind pressure or the like and accidental disaster due to this, that is, damage to the structure.

In addition, since the seismic isolation structure of the present invention normally keeps the structure free from the foundation, that is, seismic isolation state, the seismic isolation function works reliably in the event of an earthquake and damage to the structure is ensured. It can be prevented, and power consumption can be reduced.
