In addition, since the connecting member having a long portion extending in the X-axis direction connects the pair of base-isolated main body carts sandwiching the separation space along the X-axis, the vibration of the base-isolating main body is caused by vibration. When a force is applied to deform the grid-like arrangement of the grid, the connecting member that connects the carriage is bent so as to maintain the relative arrangement of the seismic isolation body, and absorbs vibration energy.
In addition, two connecting members extending in the X-axis direction connect a pair of locations separated in the Y-axis direction of the upper base of the pair of seismic isolation bodies sandwiching the separation space along the X-axis.

Further, the carriage is guided in the Y-axis direction by two pairs of wheels rolling on two pairs of rail guide surfaces of the lower base, and the upper base is guided by one pair of wheels of the carriage. Since the rail guide surface is guided in the X-axis direction, the upper frame moves along the XY plane with respect to the lower frame.
In addition, for each set of M seismic isolation bodies arranged along the X-axis, a plurality of tension generating members pulls the horizontal movement of the object with respect to the gantry. The force acting on the object can be transmitted to the upper base via a tension generating member that expands and contracts.

In this way, when horizontal acceleration acts on the object due to an earthquake or the like, the upper base 130 moves horizontally relative to the lower base 110.

  Since the structure of the base isolation body 100 is the same as that of the base isolation floor structure according to the first embodiment, the description thereof is omitted.

The X-axis pedestal coupling member 200 is composed of two X-axis pedestal long members 210 and two pairs of X-axis pedestal coupling members 220.
The two pairs of the X-axis pedestal coupling members 220 include a pair of end portions of the two X-axis gantry long members 210 and the pair of seismic isolation main bodies 100 sandwiching the X-axis separation space Sx.

The upper base 130 is coupled to a pair of locations facing each other across the Y-axis separation space Sy and spaced apart along the X-axis.
For example, the two pairs of Y-axis pedestal coupling members 320 are a pair of seismic isolation bodies that sandwich the Y-axis separation space Sy between each pair of two Y-axis gantry long members 310. A pair of locations separated along the X-axis of the side portions opposed to each other across the Y-axis separation space Sy of the 100 pedestal 130 are coupled in a relatively non-rotatable manner.

In this way, when horizontal acceleration acts on the object due to an earthquake or the like, the upper base 130 moves horizontally relative to the lower base 110. Vibration energy is attenuated by the frictional force of the internal mechanism of the seismic isolation body during horizontal movement.
When there is a difference in the direction and magnitude of horizontal acceleration acting on a plurality of seismic isolation bodies, a force is generated to change the grid arrangement of the plurality of seismic isolation bodies. In such a case, a bending force acts on the X-axis gantry coupling member 200 and the Y-axis gantry coupling member 300, and the X-axis gantry coupling member 200 and the Y-axis gantry coupling member 300 generate vibration energy. Absorbing as bending energy, the upper base and the lower base move relatively horizontally, and the vibration energy is attenuated by the frictional force of the internal mechanism of the seismic isolation body.
In particular, vibration energy can be efficiently attenuated by including a so-called spring element that generates a restoring force according to the distance of horizontal movement when the seismic isolation main body 100 moves horizontally.

(Handling method)
When performing maintenance under the seismic isolation floor,
The four Y-axis on-base mount connecting members 300 are connected, rotated around the axis of the pin 316, folded as shown in FIG. 9, and removed.

Below, the effect | action of the seismic isolation floor structure concerning 3rd embodiment of this invention is demonstrated.
When horizontal acceleration acts on the object due to an earthquake or the like, the upper base 130 moves horizontally relative to the lower base 110. Vibration energy is attenuated by the frictional force of the internal mechanism of the seismic isolation body during horizontal movement.
When there is a difference in the direction and magnitude of horizontal acceleration acting on a plurality of seismic isolation bodies, a force is generated to change the grid arrangement of the plurality of seismic isolation bodies. In such a case, a bending force acts on the X-axis gantry coupling member 200 and the Y-axis gantry coupling member 300, and the X-axis gantry coupling member 200 and the Y-axis gantry coupling member 300 serve as bending energy. The vibration energy is absorbed, the upper base 130 and the lower base 110 are moved relative to each other horizontally, and the vibration energy is attenuated by the frictional force of the internal mechanism of the base isolation body.
In particular, vibration energy can be efficiently attenuated by including a so-called spring element that generates a restoring force according to the distance of horizontal movement when the seismic isolation main body 100 moves horizontally.

Moreover, the pallet and the loading apparatus according to the embodiment of the present invention have the following effects depending on the configuration.
M × N seismic isolation bodies 100 are arranged in a grid pattern along the X and Y axes with the spacing spaces Sx and Sy between them, and the connecting members 200 and 300 are placed in each spacing space. The connecting member having a long portion extending in the X-axis direction connects the pair of bases 130 of the seismic isolation body 100 sandwiching the separation space Sx along the X-axis, and the long portion extending in the Y-axis direction. Since the connecting member that connects the pair of bases 130 of the seismic isolation main body 100 that sandwich the separation space Sy along the Y axis is mutually connected, the grid-like arrangement of the base plate of the base isolation main body 100 is deformed by vibration. When the intended force is applied, the connecting members 200 and 300 that connect the upper base elastically deform so as to maintain the relative arrangement of the seismic isolation main body 100 and absorb vibration energy.
Further, since the connecting member 200 having a long portion extending in the X-axis direction connects the carts 120 of the pair of seismic isolation main bodies 100 sandwiching the separation space Sx along the X-axis, the seismic isolation main body is caused by vibration. When a force is applied to deform the grid-like arrangement of the 100 grids, the connecting member 400 that couples the carriage 120 is elastically deformed so as to maintain the relative arrangement of the seismic isolation body 100 and absorbs vibration energy. .
In addition, the two connecting members 200a and 200b extending in the X-axis direction connect a pair of locations separated in the Y-axis direction of the pair of base-isolated main body 100 with the separation space sandwiched along the X-axis. As a result, when a force is applied to deform the grid-like arrangement of the base plate of the base isolation body due to vibration, a pair of connecting members that connect the upper base along the X-axis are relative to the base isolation body. It absorbs vibration energy by elastic deformation so as to maintain the arrangement.
Further, the two connecting members 300 extending in the Y-axis direction connect a pair of locations separated in the X-axis direction of the pair of bases 130 of the base isolation body 100 that sandwich the separation space along the Y-axis. As a result, when a force is applied to deform the grid-like arrangement of the base plate of the seismic isolation body due to vibration, a pair of connecting members that connect the upper base along the Y axis change the relative arrangement of the base isolation body. It absorbs vibrational energy by elastic deformation to maintain.
The connecting member 300 includes five parts including a long member, four connecting pins, and a connecting member. The four connecting pins flexibly connect the five parts, and the shaft of the long member Since the cores are aligned in a straight line, the connecting member 300 is connected to a pair of bases of the seismic isolation body sandwiching the separation space Sy, so the five parts of the connecting member are centered on the four connecting pins. The connecting member can be easily detached from the upper base.
In addition, since the protrusions W that fit into the recesses H provided in the upper base are provided at both ends of the connecting member 300 extending in the Y-axis direction, the end of the connecting member 300 is firmly attached to the upper base 130. The connection force can be transmitted to the connecting member to deform the grid-like arrangement of the base plate of the seismic isolation body caused by vibration.
Further, the carriage 120 is guided in the Y-axis direction by two pairs of Y-axis wheels 122 that roll on two pairs of rail guide surfaces of the lower base, and the upper base 130 is a pair of X-axis of the carriage 120. Since the guide is guided in the X-axis direction by the pair of rail guide surfaces guided by the shaft wheel 123, the upper base moves along the XY plane with respect to the lower base.
In addition, for each set of M seismic isolation main bodies 100 arranged along the X axis, a plurality of tension generating members 600 pull the horizontal movement of the object 20 with respect to the gantry 130. Alternatively, the force acting on the plurality of objects can be transmitted to the upper frame via the tension generating member 600.
In addition, the center part of the guide surface is recessed when it is directed on the guide surface, and it has a slope that rises upward as it moves from the center part to both sides. The restoring force toward it acts.
Further, since the wheel is supported on the wheel shaft via the bush, a frictional force is generated when the wheel rolls, and a damper function that attenuates vibration energy is exhibited.

The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the scope of the invention.
In the seismic isolation main body, the example in which the upper base or the lower base is provided with the rail member and the carriage is provided with the wheel guided by the rail member of the base is not limited thereto, but the upper base or the lower base is provided with the wheel, The carriage may include a rail member.
Although the case where there are a plurality of M × N M and N has been described as an example, the present invention is not limited to this, and one of M and N may be 1 and the other may be a plurality.
