Description

  The present invention is provided with a floor joint device in which a tip portion of a floor joint plate protrudes on the floor surface when the joint portion becomes narrow due to an earthquake in a part such as a passageway having a floor surface and a wall surface through the joint portion. The present invention relates to a joint device.

  Conventionally, such joint devices are located at the center of the joint plate for the joint when the left and right buildings are swung in the horizontal direction due to the earthquake between the floor frames on the joint side of the left and right buildings. Floor joint device that allows left and right buildings to move in the left and right direction, and moving joint cover that slides up and down to the upper and lower parts of the wall joint cover of the wall joint device that covers the joints between the wall surfaces of the left and right buildings Even if the left and right buildings swing in different vertical directions due to an earthquake, it is considered that the shaking movement is absorbed by the vertical movement of the moving joint cover and is absorbed without damaging the wall joint cover etc. .

  However, when the left and right buildings swing in different vertical directions due to the earthquake, the floor joint plate becomes inclined and presses the moving joint cover, so that the moving joint cover and the wall joint cover are galling and sliding. There was a drawback of being unable to move and damaging.

  In recent years, floor joint devices that absorb the shaking movement of the floor joint plate by causing the tip portion to pivot upward when the joint portion becomes narrow due to an earthquake have been used. Therefore, when the floor joint plate is used to push up the movable joint cover of the wall joint device, a pushing force is applied to the movable joint cover due to the inclination of the floor joint plate, and the movable joint cover and the wall joint cover are galling. In addition, there is a disadvantage that the problem that the moving joint cover cannot slide is caused in the same manner.

A wall joint device that covers a joint portion between the wall surfaces of the left and right buildings at a site where the joint device is provided, wherein the wall joint device has the joint between the wall surfaces of the left and right buildings as the floor. The joint cover of the U-shaped or lip groove-shaped steel shape that covers the joint plate so as to have a gap, and the joint cover can be covered without being damaged even if the joint portion is widened or narrowed. Left and right building joints A joint cover support attached to the side wall surface and attached to the lower end portion of the joint cover so as to be slidable in the vertical direction. The rear end side of the floor joint plate is in contact with the floor joint plate from the center. A slide joint cover formed with a notch that does not abut the floor joint plate on the tip side, and a notch portion of the slide joint cover, and the tip of the floor joint plate rotates upward. Thus, the joint device is constituted by a shielding plate attached to the slide joint cover so that the floor joint plate slides in the rotational direction of the floor joint plate.

As is clear from the above description, the present invention has the following effects.
(1) According to claim 1, even if the joint portion becomes narrow due to an earthquake and the tip portion of the floor joint plate rotates upward to become an inclined surface, the cut joint portion of the slide joint cover of the wall joint device is covered. The shielding plate can be pushed up smoothly with the floor joint plate.
Therefore, it is possible to efficiently prevent the wall joint device from being damaged by the shaking motion at the time of the earthquake in which the joint portion becomes narrow.
(2) According to (1), the joint between the wall surfaces of the left and right buildings can be covered with the joint cover, the slide joint cover, and the shielding plate.
Therefore, it can be used safely without a gap opening in the joint.
(3) According to the above (1), since the center portion of the lower end portion of the slide joint cover is pressed by the floor joint plate, the slide joint cover is smoothly pressed upward and slid smoothly. it can.
(4) According to the above (1), it is only necessary to form a notch in the slide joint cover and to attach a shielding plate that slides the notch in the rotational direction of the floor joint plate to the slide joint cover. Is simple and can be installed easily.
(5) In the second aspect, the same effects as in the above (1) to (4) can be obtained, and the shielding plate can be easily attached to the slide joint cover.
(6) In the third aspect, the same effects as in the above (1) to (4) can be obtained, and the shield plate can be attached to the slide joint cover so as not to come off.
