Description

  The present invention relates to a ceiling joint device in the case where a ceiling is provided between left and right buildings provided via joint portions.

  Conventionally, this type of ceiling joint device is provided with a pair of ceiling joint panels on the left and right housings of the joint portion via hinge members so as to cover the joint portion, and a pair of ceiling joints during a swinging movement that narrows the joint portion due to an earthquake. By the inclined surface of the front end portion of the panel, the panel is rotated upward or downward to absorb the shaking motion.

  For this reason, it is possible to safely absorb small swinging movements in the left and right directions, but if the building on the left and right is shaken by an earthquake for more than half of the horizontal dimension of the joints, one ceiling joint panel will move to the left and right joints. There was a drawback that it was pressed and damaged by the side housing.

  Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

In the first embodiment for carrying out the present invention shown in FIG. 1 to FIG. 6, 1 is a ceiling joint device in which a ceiling 4 is provided between left and right buildings 3 and 3 provided via a joint portion 2. The ceiling joint device 1 is fixed to the outer wall surface of the left and right buildings 3 and 3 on the joint portion 2 side and above the ceiling portion with a plurality of anchor bolts 5 or the like, and is at least two pairs or more forming a casing. a support 6,6,6,6, mounted on a support 6, 6 attached to one of the building 3 side of the support member 6,6,6,6 over the two pairs, it is the distal end At least two or more central support mechanisms 8 and 8 for supporting the substantially inverted trapezoidal central support body 7 positioned at the center of the joint portion 2 so as to be able to rotate downward, and at least two of these. The central support mechanisms 8 and 8 are connected to the central portion of the joint portion 2 when the central support 7 is normally used. When the joint portion 2 is positioned and becomes narrow due to an earthquake, the central support mechanism supports 9 and 9 for rotating the central support 7 downward, and the tip portion is supported by the at least two central support mechanisms 8 and 8. A plurality of hinges are attached to the outer wall casings 3a and 3a of the ceiling portions of the left and right buildings 3 and 3 so that the rear ends are supported by both front end portions 7a and 7a of the central support body 7 being in a horizontal state. The left and right joint ceiling panels 11 and 11 attached by the member 10 and the left and right joint ceiling panels 11 and 11 are kept horizontal at the normal time, and when the joint portion 2 becomes narrow due to an earthquake, the tip portion is rotated downward. When the joint 2 is narrowed by an earthquake, which is fixed to the upper surfaces of the joint ceiling panel supports 12 and 12 and one of the left and right joint ceiling panels 11 and 11, the left and right joint ceiling panels 11 and 11 Engage with the tip Is composed of a stopper 13 can keep the state.

  The central support mechanism supports 9 and 9 have at least two or more central support mechanisms 8 and 8 with one end attached to the tip and the other end attached to the upper end of the support 6 or 6. The center of at least two or more central support mechanisms 8 and 8 that prevent the upward biasing spring 14 and the central support 7 from rotating upward from the left and right joint ceiling panels 11 and 11. One end part is attached to the tip part side from the part, and the other end part is composed of wires 15 and 15 attached to the lower side of the supports 6 and 6.

  The left and right ceiling panel supports 12, 12 come into contact when the left and right ceiling panels 11, 11 are in a horizontal state, and stopper pieces 16, formed at the lower ends of the supports 6, 6, 6, 6. 16, 16, 16, and one end that urges the stopper pieces 16, 16, 16, 16 are attached to a portion closer to the tip than the center of the left and right ceiling panels 11, 11, and the other end The portion is composed of urging springs 17, 17, 17, 17 attached to a portion near the top of the tip of the support 6, 6, 6, 6.

  Note that an existing roof joint cover device 18 that covers the joint portion 2 between the left and right buildings 3 and 3 is installed above the ceiling joint device 1 on the uppermost floor.

  In the ceiling joint device 1 having the above-described configuration, the right and left ceiling panels that are supported by the left and right ceiling panel supporters 12 and 12 at the joint portion 2 between the ceiling portions of the left and right buildings 3 and 3 are generally horizontal. 11 and 11 and the central support 7 supported by the central support mechanism supports 9 and 9 are covered between the left and right ceiling panels 11 and 11 as shown in FIG.

  When the left and right buildings 3 and 3 are shaken by the earthquake and the joint portion 2 is narrowed, the central support 7 keeps the normal state by the central support mechanism supports 9 and 9 as shown in FIG. 11 and 11 move downward along the inclined surfaces 7a and 7a of the central support 7 against the urging force of the left and right ceiling panel supports 12 and 12, and the tip of the ceiling panel 11 is moved to the stopper piece 16. The parts come into contact with each other and rotate downward in a palm-mounted state to absorb the shaking motion.

  Further, when the joint portion 2 is greatly narrowed, the center support mechanism supports 9 and 9 are rotated downward against the urging force of the support members 9 and 9 to absorb the shaking motion.

  When the shaking movement due to the earthquake stops, the original state is automatically restored by the ineffective force of the left and right ceiling panel supports 12, 12.

  When the left and right buildings 3 and 3 are shaken by the earthquake and the joint portion 2 is widened, the left and right ceiling panels 11 and 11 are kept horizontal by the left and right ceiling panel supports 12 and 12 as shown in FIG. The tip part moves away from 7 to absorb the shaking movement.

  For this reason, even if the joint portion 2 is narrowed or swung so as to be widened by an earthquake, the central support 7 and the left and right ceiling panels 11 and 11 do not move upward from the horizontal state. A large moving space above 11 is unnecessary, and a problem of colliding with a roof joint cover device (which is not shown) can be solved.
