Description

[Detailed Description of the Invention] The present invention relates to an improvement of a joint cover that covers the joints of adjacent buildings.

Some joint covers of this type have a simple structure in which the base is fixed to each building, but with such a structure, the buildings may sway vertically, horizontally, and longitudinally due to earthquakes or rainstorms. In some cases, cracks may occur in the mounting base of the joint cover, and in some cases, the outer wall of the building may be damaged.
Therefore, as a response to this,
In No. 38807, a structure was devised that absorbed the above-mentioned relative vibration between buildings and eliminated the above-mentioned drawbacks.

By the way, in this structure, as shown in FIG. 4, connecting bodies b, b are rotatably fitted to a pair of fixed bodies a, a, which are respectively fixed to mutual wall surfaces of adjacent buildings, by means of circular concavities and convexities c. , a pair of cover plates d, d are fixed to the connecting bodies b, b, respectively, and their tips are overlapped, and the joint parts are covered by the cover plates d, d, and the tilting of the connecting bodies b, b is This allows the cover plates d, d to move in accordance with the relative rocking between the buildings.

By the way, in the joint cover installation work described above, when installing the cover plate d, it is necessary to overlap the ends thereof, so fixing body a is fixed to the building wall surface, and connecting body b is fitted to the fixed body a. After that,
It is necessary to screw the end of the cover plate d onto the outside of the circular unevenness c using a mounting screw e. Therefore, as shown in FIG. 5, in the above structure, the connecting body b
is rotatable left and right with respect to the fixed body a, so when the mounting screw e is screwed in, the connecting body b tilts outward and becomes unstable, making its installation extremely difficult. Furthermore, it is necessary to embed a stretchable flexible sealing material g between the outside of the connecting body b and the mortar f that is applied to the wall surface with a predetermined thickness.
In this mounting operation, the connecting body b sways, making it difficult to make its surface flush with the mortar f.

The present invention aims to eliminate the drawbacks of the conventional device, and includes an L-shaped connecting piece interposed between the fixed body and the connecting body, with one end of the L-shaped connecting piece facing outward in surface contact with the fixed body. , the circular fitting portion of the end portion is fitted so as to be rotatable relative to the fixed body, and the end portion on the other side is further fitted to the connecting body such that the connecting body is rotatable only inward. When the connecting body is in a fixed configuration and a load is applied outside the connecting body, the connecting body cannot rotate outwardly relative to the connecting piece, and the connecting piece is in surface contact with the connecting body. The connecting body is not rotated relative to the fixed body by the pressing operation from the connecting body, and the connecting body is prevented from rotating due to the applied load. It allows left and right rotation, and allows the cover plate to follow the movement of buildings.
