Description of the Related Art Conventionally, as shown in FIG. 1, in order to make it easy to move between two independent buildings 1 and 2 adjacent to each other, the building is laid between the two buildings 1 and 2 and ground. The communication passage 3 is provided at a high place away from the road, and this kind of communication passage 3 is designed to absorb bending deformation and temperature deformation caused by its own weight, a dynamic load traveling on the passage, and the like. To both buildings 1 and 2.

As shown in FIG. 2, one end of a communication passage 3 interconnecting the two buildings 1 and 2 is connected to the lower side thereof. The connecting member 3a integrally provided on the support 4 of the one building 1
A roller provided with a support member 5 fixed to the base member via a pin 10 so as to be rotatable around a horizontal axis, and a lower surface of the other end side provided on a support base 6 of the other building 2 via a support member 7. The roller 11 is allowed to absorb expansion and contraction in the length direction of the passage due to temperature deformation by, for example, rolling support by mounting on the roller 11, and the bending deformation in the vertical direction caused by its own weight or dynamic load is allowed by coupling with the pin 10. I try to absorb it.

れていなかった。However, in the conventional communication passage structure, measures against distortion in the vertical (Z-axis) direction and the passage length (Y-axis) direction (see FIG. 1) due to its own weight and temperature change are taken to prevent deformation. Although it has a structure that can be absorbed,
No consideration has been given to the case where a relative displacement in the horizontal (X-axis) direction parallel to the buildings 1 and 2 is large due to an earthquake or the like.

問題があった。That is, the two buildings 1 and 2 connected by the communication passage 3 often have different structures, and when the buildings 1 and 2 having such different structures shake due to an earthquake or the like, The shaking vibration modes are different from each other. Therefore, the relative positional relationship between the supports 4 and 6 of the two buildings 1 and 2 supporting both ends of the communication passage 3 is not two-dimensionally approaching and separating along the length of the passage. The structures are relatively displaced dimensionally, and torsional vibration also acts on the buildings 1 and 2. For this reason, in the conventional communication passage structure without the relative displacement absorbing mechanism in the X-axis direction, excessive stress is applied to the communication passage 3 at the time of occurrence of a large earthquake or the like, or the communication passage 3 is damaged or damaged. Also, there is a problem that damage and deterioration are likely to progress.

せたものである。[0006] The structure of a building includes a base-isolated structure, a non-base-isolated structure, a rigid structure, a flexible structure, and the like. In recent years, a new base-isolated structure is provided adjacent to an existing non-base-isolated structure. In many cases, structures or flexible structures are built, and both buildings are connected by a communication passage in a high space away from the ground, and at least one of the connected structures is seismically isolated or flexible. In the case of the structure, the difference between the swing modes is particularly remarkable, and the two-dimensional relative displacement increases. Therefore, in the conventional communication passage structure, the displacement cannot be sufficiently absorbed, and an excessive stress or distortion is generated, which easily causes deterioration or breakage. The above seismic isolation structure is a structure in which the upper structure is supported on the lower structure via an elastic member such as an isolator that has excellent vertical load-bearing capability and high horizontal displacement. is there.

の相対変位を吸収可能な機構を有している構成とした。To achieve the above object, the present invention provides a communication passage structure for interconnecting two independent buildings in a space away from the ground, wherein the communication passage has two ends. A structure is provided that is rotatably supported in the horizontal direction with respect to both buildings and has a mechanism capable of absorbing relative displacement in the passage length direction between the two buildings.

く、破損や劣化を可及的に防ぐことができる。According to the above configuration, even if a two-dimensional relative displacement or torsion in the horizontal direction occurs between two buildings having different vibration modes due to a large earthquake or the like, both ends of the communication passage are connected to the two buildings. It is pivotable with respect to each other, and fluctuations in the distance between the support points of both buildings are allowed to be absorbed by the displacement absorption mechanism in the passage length direction.
Excessive stress and distortion do not occur in the communication passage, and breakage and deterioration can be prevented as much as possible.

の吸収動作に対し緩衝作用を発揮する。Here, a clearance for absorbing relative displacement is provided at a portion where the communication passage and the two buildings are joined, and it is desirable that an elastic member is interposed at the portion where the connection passage is absorbed. The elastic member is deformed in accordance with the change in the clearance between the building and the communication passage, thereby closing the gap between the two, and has a buffering effect on the operation of absorbing the relative displacement.
