Description

[0001]
[Industrial application fields]
The present invention relates to an improvement in a joint cover device that covers joints between outer walls of adjacent buildings.
[0002]
[Prior art]
In this type of joint cover device, there are three cover plates: a central cover plate disposed in the center of the joint, and left and right cover plates disposed on the sides of the joint with the end portions overlapped on the cover plate. What covers a joint by a cover board is well-known.
[0003]
As shown in FIG. 6, the joint cover device has fixed bodies a and a ′ fixed to the wall surfaces of adjacent buildings x and x, respectively, and pivots in the left and right directions on both fixed bodies a and a ′. The connecting bodies b and b 'that are fitted to each other, the sliding arm c that is fixed to one connecting body b and passed in the joint direction, and the connecting body b' that is fixed to the other connecting body b 'and inserted in the joint direction. The sliding arm c is slidably inserted from the end part into the passed supporting arm d and the sliding path f of the sheath frame e fixed to the back surface, and the back surface is supported by the supporting arm d. A pair of left and right end cover plates h, h ′ whose outer ends are fixed to the central cover plate g and the coupling bodies b, b ′ and whose inner end portions are superimposed on the central cover plate g. And.
[0004]
Then, when the building x, x is relatively displaced in the left-right direction (direction in which the joint width is changed), the sliding arm c moves and slides in the sliding path f formed on the back surface of the central cover plate g. The end cover h supported by the coupling body b to which the arm c is coupled moves to the left and right with respect to the central cover plate g. Moreover, since the back surface is only supported by the support arm d at the other end portion of the central cover plate g, the end cover h supported by the connecting body b ′ to which the support arm d is connected. It can be moved with respect to '. For this reason, the end cover plates h and h ′ on the left and right of the center cover plate g held on the back by the sliding arm c and the support arm d are displaced relative to each other in the width direction of the adjacent buildings x and x. It follows and moves in the left-right direction while maintaining the overlapping state, and can absorb the relative displacement.
[0005]
[Problems to be solved by the invention]
In the joint cover device having such a configuration, since the joint cover is constituted by the three cover plates as described above, there is a limit to the follow-up performance. That is, the lateral movement amounts of the end cover plates h and h ′ with respect to the central cover plate g are in the range of the width A in the outward direction from the position shown in FIG. 6, and the range of the width B in the inward direction. It becomes. For this reason, it is not possible to cope with a case where the building is greatly displaced in the left-right direction beyond the allowable movement amount, and the building is damaged at the fixing portion between the joint cover device and the building, or the joint cover device itself Could be damaged.
[0006]
In addition, when the lateral movement allowance is increased with such a configuration, the width W of the entire joint cover device is increased, and the joint cover device is conspicuous and the appearance of the building is impaired.
[0007]
It is an object of the present invention to provide a joint cover device that can greatly increase the lateral movement allowance without changing the overall width of the device.
[0008]
