Description

  The present invention relates to a ceiling joint device for covering ceiling joint portions of left and right buildings provided via joint portions.

  Conventionally, this type of ceiling joint device has an upper surface formed with a raised portion on the joint portion side end of the ceiling material of one building, and the rear surface of the other building facing the ceiling material. A joint ceiling cover is provided that is pivotably attached via an end hinge member and is positioned so as to abut the tip portion of the ceiling member against the raised portion of the inclined surface of the ceiling material. The rear end is fixed to the upper surface of the building, the front end is separated from the upper surface of the joint ceiling cover, and at least two raised covers are slidable on the suspension guide between the ceiling material and the ceiling frame The support arm is supported, and when the joint portion formed on the at least two raised cover support arms becomes narrow, the suspension guide guides the joint cover so that the joint ceiling cover is positioned above the ceiling material and absorbs the shaking motion. Do It is composed of a elevated guide member.

  For this reason, when the joint portion becomes narrow due to an earthquake, the joint ceiling cover is formed on at least two lift cover support arms after coming into contact with the raised portion which is an inclined surface of the ceiling material and guided upward. The raised guide member is guided by the suspension guide, and the joint ceiling cover is positioned above the ceiling material.

  Therefore, when the joint ceiling cover becomes narrow due to the earthquake, the joint ceiling cover and the ceiling material collide with each other and move upward.Therefore, the ceiling material and the joint ceiling cover are liable to be damaged, When the joint part is narrow, the joint part is rotated with the hinge part as a fulcrum, and the joint ceiling cover located at the joint part is in an unsightly position.

Japanese Patent No. 3408181

  In view of the above-described conventional drawbacks, the present invention, when a shaking movement that narrows the joint portion due to an earthquake occurs, the front end portion of the joint ceiling cover and the front end portion of the movable ceiling joint cover do not collide, An object of the present invention is to provide a ceiling joint device that is simple in structure and can be easily installed by rotating the tip of the movable ceiling joint cover upward to absorb the shaking motion.

  Another object of the present invention is to provide a ceiling joint device that can absorb the swinging motion by play in the front-rear direction of the receiving tool and the rotating arm even when the left and right buildings swing in different front-rear directions. Yes.

  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. 11, 1 is a ceiling joint device of the present invention that covers the ceiling joint portions of the left and right buildings 3, 3 provided via the joint portion 2. Thus, the ceiling joint device 1 is suspended and fixed to the ceiling housing 4 of one of the left and right buildings 3 and 3 by a plurality of suspension tools 5 and the tip is predetermined to the joint side end. A rear end on the outer wall surface 3a of the other building 3 of the left and right buildings 3 and 3 facing the ceiling material 6 and the ceiling material 6 provided so as to have the same dimensions as the width of the joint portion 2, for example A joint ceiling cover 8 that covers the joint portion 2 in which the portion is fixed and the inclined surface 7 is formed on the upper surface of the tip portion, and the tip portion of the ceiling material 6 can be maintained in a horizontal state via a hinge member 9; In addition, the tip with the inclined surface 10 formed on the lower surface can be rotated upward. A movable ceiling joint cover 11 that covers the space between the ceiling material 6 and the joint ceiling cover 8, a channel-shaped receiving member 12 fixed to the upper surface of the tip of the movable ceiling joint cover 11, When the joint portion 2 is fixed to the outer wall surface 3a of the other building 3 at the upper position of the joint ceiling cover 8 and the joint portion 2 becomes narrow due to an earthquake, the front end portion of the movable ceiling joint cover 11 is engaged with the receiver 12. When the movable ceiling joint cover 11 cannot be sufficiently held in a horizontal state by the pivot arm 13 that rotates the movable ceiling joint cover 11 upward without colliding with the joint ceiling cover 8 and the hinge member 9. The upper ceiling part of the movable ceiling joint cover 11 to be used and a flexible suspension 14 such as a rope, a wire, a chain, etc. fixed to the ceiling casing 4 at a part facing the part. .

  The ceiling material 6 may be directly suspended by a plurality of hanging tools 5, and uses a ceiling base plate fixed to a ceiling base material suspended by a plurality of hanging tools 5. May be.

  The receiver 12 is a channel formed in a width dimension that allows the pivot arm 13 to move in the front-rear direction, and is attached to the tip of the movable ceiling joint cover 11 with screws 15 that project outward at both ends. , 16 and a roller 18 rotatably attached to a horizontal member 17a of the receiver body 17.

  The pivot arm 13 is configured so that the top of the movable ceiling joint cover 11 can pivot upward before the top of the movable ceiling joint cover 8 collides with the tip of the joint ceiling cover 8 when the joint becomes narrow due to an earthquake at the top end of the tip. While being in contact with the roller 18 of the tool 12, it is formed on the inclined surface 19, and is fixed to the outer wall surface 3a of the other building 3 in an inclined state.

  As shown in FIGS. 1 and 2, the ceiling joint device 1 having the above configuration normally covers the ceiling joint portion 2 with the ceiling material 6, the movable ceiling joint cover 11 and the joint ceiling cover 8 positioned in a substantially flat state. Yes.

When one building 3 that is the left and right buildings 3 and 3 and the other building 3 swing so that the joint portion 2 is narrowed by the earthquake, the tip of the movable ceiling joint cover 11 is connected to the joint ceiling cover 8 as shown in FIG. Before colliding with the tip of the rotary arm 13, the tip of the rotary arm 13 enters the lower part of the roller 18 of the support 12, and the movable ceiling joint cover 11 is rotated upward along the inclined surface 19 of the rotary arm 13. Move and absorb the shaking movement.

  When one building 3 and the other building 3 are swung so that the joint portion 2 is widened by the earthquake, the movable ceiling joint cover 11 and the joint ceiling cover 8 are moved away from each other as shown in FIG. To absorb.

  When one building 3 and the other building 3 are swung in different front and rear directions due to the earthquake, the movable ceiling joint cover 11 and the joint ceiling cover 8 move in different front and rear directions as shown in FIG. 13 slides back and forth in the receptacle 12 to absorb the shaking movement.

  When the shaking motion due to the earthquake stops, the movable ceiling joint cover 11 is attached to the ceiling material 6 and is supported by the flexible suspension 14 in order to maintain the horizontal state, and the one building 3 Since the joint ceiling cover 8 is fixed to the outer wall surface 3a of the other building 3, it automatically returns to its original state.

[Different forms for carrying out the invention]
