Description

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

  Conventionally, in order to install a ceiling joint device on the ceiling part of the joint part of the left and right buildings, the ceiling joint plate covering the joint part is damaged by the swinging motion that narrows the joint part by the wall surfaces of the left and right buildings In order to prevent this, a ceiling joint plate rotating mechanism is used that rotates the ceiling joint plate upward or downward when the joint portion becomes narrow using a link mechanism.

  However, the ceiling joint plate rotating mechanism using this link mechanism has a drawback in that the ceiling joint plate may be damaged because it does not operate sufficiently following the shaking motion of a sudden earthquake. .

Japanese Patent No. 3604647

  In the present invention, in view of the above-described conventional drawbacks, when a shaking motion of an earthquake that causes the joint portion to narrow suddenly occurs and the pair of ceiling joint plates hit each other, the tip portion that automatically hits rotates downward. An object of the present invention is to provide a ceiling joint device that can efficiently prevent damage to a pair of ceiling joint plates, automatically return to its original state when the shaking motion stops, and can normally cover the ceiling joint part. It is said.

  The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.

  However, the drawings are for explanation only and do not limit the technical scope of the present invention.

In order to achieve the above object, according to the present invention , the angle-shaped movable member at the tip portion fixed to the wall surface of the ceiling portion on the joint portion side of the left and right buildings provided through the joint portion is separated from the wall surface. A pair of hinge members located below and a pair of hinge members positioned so that a tip end portion attached to an angle-shaped movable member of the pair of hinge members is flush with a substantially central portion of the joint portion. A ceiling joint plate and one end for energizing the tip of the pair of ceiling joint plates so as to be always positioned upward are attached to a portion near the tip of the pair of ceiling joint plates, and the other end is the ceiling portion. And a pair of stopper pieces for preventing the pair of ceiling joint plates from rotating upward from a horizontal state. Configure the device It is.

As is clear from the above description, the present invention has the following effects.
(1) According to claim 1, when the joint portion becomes narrow due to the shaking motion of the earthquake, the pivotal support portions of the pair of hinge members that attach the pair of ceiling joint plates to the wall surface from the positions of the tip portions of the pair of ceiling joint plates that come into contact Is located at the top, so that when the tip ends of the pair of ceiling joint plates are in a collision state, the tip portions of the pair of ceiling joint plates are automatically rotated downward against the biasing force of the bias spring. Thus, damage to the pair of ceiling joint plates can be efficiently prevented.
(2) According to the above (1), since the pair of ceiling joint plates can be made almost horizontal by the biasing spring and the pair of stopper pieces, even if the joint becomes wide due to the shaking motion of the earthquake, When the shaking motion stops, it can be automatically restored to its original state.
(3) According to the above (1), the gap between the tip portions of the pair of ceiling joint plates can be covered by the bar member that is always located in the central portion of the joint joint portion with a plurality of central maintenance link mechanisms It is possible to prevent the tip portion from rotating upward as compared to the horizontal state of the pair of ceiling joint plates.

  Therefore, the aesthetic appearance can be improved by the bar member, and the damaging movement of the pair of ceiling joint plates can be prevented.
