DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
[0008]
In the first embodiment of the present invention shown in FIG. 1 to FIG. 9, 1 covers the left and right outer wall housings 3 a, 3 a on the joint part side of the left and right buildings 3, 3 built via the joint part 2. In the joint device of the present invention, the joint device 1 is rotatably attached to one of the left and right outer wall housings 3a and 3a via a hinge member 4, and the back surface side of the tip is formed on the inclined surface 5. The joint cover 6 that covers the portion other than the other side of the joint portion 2 is brought into contact with the tip end portion of the inclined surface 7 that can come into surface contact with the tip end portion of the joint cover 6. A joint cover support piece 9 rotatably attached to the other outer wall housing 3a on the joint part side of the left and right buildings 3 and 3 through which the tip of 6 can be slid forward. The rotation of the joint cover 6 on the back of the joint cover 6 The rotary shaft 11 is attached by the shaft support members 10 and 10 so that the axial center is located in the direction, and one end is attached to the tip of the joint cover support piece 9 and the other end is at least one on the rotary shaft 11. The wire 14 is attached by way of a guide roller 12 and a spring 13 so as to be wound more than once and to be biased to the outer wall housing 3a in the closing direction of the joint cover 6.
[0009]
As shown in FIG. 4, the joint cover 6 includes a joint frame 17 including a rectangular frame member 15 and reinforcing bars 16 fixed so as to be positioned in the frame member 15 at predetermined intervals. A rotary shaft 11 that is rotatably attached to a substantially central portion of the frame 17 by using shaft support members 10 and 10 and a joint cover panel 18 that covers the joint cover frame 17 and forms an inclined surface 5 at the tip portion. It consists of and.
[0010]
As shown in FIGS. 1 and 3, the joint device 1 having the above configuration is normally urged by the spring 13 so that the tip of the joint cover 6 and the tip of the joint cover support piece 9 are in contact with each other. The joint portion 2 is covered with the formed wire 14.
At this time, one end of the wire 14 is attached to the joint cover support piece 9, wound around the rotating shaft 11 attached to the joint cover 6 one or more times, and biased by the spring 13. 9 and the joint cover 6 can be prevented from shaking.
[0011]
When the left and right buildings 3 and 3 swing in different directions due to an earthquake or the like and the joint portion 2 becomes wider, the tip portion of the joint cover 6 moves away from the tip portion of the joint cover support piece 9 as shown in FIG. At this time, the joint 14 is separated by the wire 14 biased by the spring 13 while keeping the joint cover 6 positioned via the joint cover support piece 9 and the rotating shaft 11.
When the swaying motion stops, the wire 14 urged by the spring 13 automatically returns to the original state where the tip of the joint cover support piece 9 and the tip of the joint cover 6 abut.
[0012]
When the joint portion 2 is swung so as to become narrow, the tip end portion of the joint cover 6 slides on the tip end portion of the joint cover support piece 9 as shown in FIG.
At this time, the wire 14 wound around the rotary shaft 11 slides in the direction of the hinge member 4 to which the joint cover 6 is attached, and keeps the state in which the joint cover 6 is always urged to contact the joint cover support piece 9. Yes.
[0013]
When the left and right buildings 3 and 3 swing in different longitudinal directions, the joint cover support piece 9 and the joint cover 6 rotate from the hinge members 4 and 8 as shown in FIG. 9 to absorb the swinging motion. .
[0014]
