Further, it is possible to reduce the gap D ₁ of the between the vehicle housing portion 32 and the upper structure 14, it is possible to secure a wide interior space of the upper structure 14 (living space, etc.).

  Next, a second embodiment will be described. In addition, the thing of the same structure as 1st Embodiment attaches | subjects the same code | symbol, and abbreviate | omits suitably and demonstrates.

  As shown in FIG. 3, in the structure 60 according to the second embodiment, the lower structure 12 includes a restriction member 62 as a pair of restriction portions that restricts the horizontal displacement of the lower end portion 34 </ b> L of the vehicle carry-out portion 34. Is provided. The pair of restricting members 62 are formed in a wall shape and are disposed on both sides in the horizontal direction of the vehicle carry-in / out part 34, and are respectively raised from the pit parts 22 of the lower structure 12. The pair of restricting members 62 restricts the horizontal displacement of the lower end portion 34L of the vehicle carry-in / out portion 34.

  On the other hand, the vertical displacement of the vehicle carry-in / out part 34 is allowed. That is, a gap is formed between the lower end portion 34L of the vehicle carry-out / delivery portion 34 and the bottom portion of the pit portion 22, and the vehicle carry-out / delivery portion 34 can be displaced in the vertical direction between the pair of regulating members 62. ing.

  Furthermore, the vehicle carry-in / out part 34 is supported by a pair of regulating members 62 so as to be rotatable around its lower end part 34L. That is, the lower end portion 34 </ b> L of the vehicle carry-in / out portion 34 is pin-joined to the lower structure 12 via the pair of regulating members 62.

In FIG. 4, the vehicle carry-out / sending part 34 is schematically shown for easy understanding. Further, in the present embodiment, as shown in FIG. 4, the vehicle carry-out / delivery part 34 does not have a truss structure or the like, and the bending rigidity of the vehicle carry-out / delivery part 34 is lower than that in the first embodiment. ing.

  Next, the operation of the second embodiment will be described.

  The lower end 34L of the vehicle carry-out / delivery part 34 is a free end. In this case, the entry / exit port 42 of the vehicle carry-in / out part 34 is likely to be displaced in the horizontal direction with respect to the vehicle entry / exit floor (the first floor) of the lower structure 12 due to wind (strong wind) or an earthquake. There is a possibility that the vehicle cannot be received.

  On the other hand, in the present embodiment, the lower structure 12 is provided with a pair of regulating members 62 that regulate the horizontal displacement of the lower end portion 34L of the vehicle carry-in / out section 34. The lower end 34L of the vehicle carry-out / delivery part 34 is pin-bonded to the lower structure 12 via the pair of regulating members 62.

  Therefore, as shown in FIG. 4, when the vehicle accommodating portion 32 is horizontally displaced during a wind or earthquake, the vehicle carry-out portion 34 rotates around its lower end portion 34L. Thereby, it is suppressed that the entrance / exit 42 of the vehicle carry-in / out part 34 shifts in the horizontal direction (position shift) with respect to the vehicle entrance / exit floor of the lower structure 12. Therefore, it becomes easy to store the vehicle in the loading / unloading port 42 of the vehicle carry-in / out part 34.

  In the present embodiment, the upper end 34 </ b> U of the vehicle carry-in / out part 34 is pin-bonded to the bottom of the vehicle housing part 32. Accordingly, when the vehicle housing portion 32 is horizontally displaced during a wind or an earthquake, the vehicle carry-out / feeding portion 34 and the vehicle housing portion 32 rotate relative to each other. Is reduced. Therefore, the breakage of the connection portion between the vehicle carry-out / shipping portion 34 and the vehicle housing portion 32 is suppressed.

  Furthermore, in this embodiment, the vehicle carry-out / delivery part 34 is pin-joined to the lower structure 12 and the vehicle housing part 32, respectively, so that the stress generated in the vehicle carry-out / delivery part 34 during wind or earthquake is reduced. Therefore, since the bending reinforcement etc. with respect to the vehicle carrying-out part 34 can be reduced, the reinforcement cost can be reduced.

  In the present embodiment, an example in which the pair of restricting members 62 are provided in the lower structure 12 is shown, but the present invention is not limited to this. The pair of regulating members 62 may be provided on the inner side surface of the lower hollow portion 20L, for example. Further, two sets of one regulating member 62 may be provided around the vehicle carry-out / delivery unit 34 so as to regulate the horizontal displacement of the vehicle carry-out / delivery unit 34 in two directions.

  Further, in the present embodiment, an example in which the upper end portion 34U of the vehicle carry-out / delivery portion 34 is pin-joined to the bottom portion of the vehicle accommodation portion 32 is shown, but the upper end portion 34U of the vehicle carry-out / delivery portion 34 is connected to the bottom portion of the vehicle accommodation portion 32. Rigid joining is also possible.

  The horizontal displacement of the entrance / exit port 42 with respect to the vehicle entrance / exit floor of the lower structure 12 is not limited to this embodiment. For example, it does not break in a wind or a small earthquake, but breaks during a large earthquake. The upper structure 14 and the lower structure 12 may be connected with a shear pin or the like. In this case, since the intermediate seismic isolation device 18 does not operate in a wind or a small earthquake, the horizontal displacement of the loading / unloading port 42 with respect to the vehicle loading / unloading floor of the lower structure 12 is suppressed.

  Next, modified examples of the first and second embodiments will be described. In the following, various modified examples will be described by taking the first embodiment as an example, but these modified examples are also applicable to the second embodiment as appropriate.

  In the first embodiment, the anti-vibration rubber 50 is used as the vibration insulating material, but the present invention is not limited to this. As the vibration insulating material, for example, silicon or a foaming resin used for a heat insulating material may be used. Further, the position where the anti-vibration rubber 50 is provided can be appropriately changed. For example, a vibration insulating material may be provided between the lower portion, the middle portion, and the upper portion of the vehicle housing portion 32 and the upper structure 14.

  In the first embodiment, the vibration isolating rubber 50 is sandwiched between the lower end portion of the vehicle housing portion 32 and the lower end portion of the upper structure body 14 so that the vehicle housing portion 32 and the upper structure body 14 are vibration-insulated. However, the present invention is not limited to this. The term “vibration isolation” as used herein means that the edge of the vehicle housing portion 32 and the upper structure 14 is cut (relatively displaceable) so that vibration is not transmitted from the vehicle housing portion 32 to the upper structure 14. . Therefore, for example, vibration isolation may be performed by forming a gap between the lower end portion of the vehicle housing portion 32 and the lower end portion of the upper structure 14 without providing the antivibration rubber 50. In this case, it is also possible to make the lower end part of the vehicle accommodating part 32 and the lower end part of the upper structure 14 contact so that vibration is not transmitted.

  Further, a vibration system (additional vibration system) in which the multi-story parking device 30 is a mass and the anti-vibration rubber 50 is an additional spring can be configured and used as a TMD (Tuned Mass Damper) or AMD (Active Mass Damper). is there.

  For example, in the structure 70 shown in FIG. 5, the upper end portion of the vehicle housing portion 32 is supported by the upper structure 14 via an anti-vibration rubber 72 as an example of a vibration insulating material. A TMD is constituted by the vibration rubber 72. The vibration of the upper structure 14 can be reduced by appropriately adjusting the natural frequency of the TMD and swinging the multi-story parking device 30 so as to cancel the vibration of the upper structure 14 during an earthquake. At this time, the multi-story parking device 30 and the upper structure 14 may be connected by a damping means such as an oil damper, or an actuator that vibrates the multi-story parking device 30 may be provided to provide an AMD.

  In addition, although the example which provided the vibration-proof rubber 72 in the upper end part of the vehicle accommodating part 32 was shown in FIG. 5, it is not restricted to this. The arrangement of the anti-vibration rubber 72 can be appropriately changed. For example, the vibration-proof rubber 72 may be provided at an intermediate portion or a lower portion of the vehicle housing portion 32.

  As mentioned above, although one embodiment of the present invention was described, the present invention is not limited to such an embodiment, and one embodiment and various modifications may be used in combination as appropriate, and the gist of the present invention will be described. Of course, various embodiments can be implemented without departing from the scope.
