Description

[Detailed Description of the Invention] The present invention relates to an improvement in 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, when the buildings shake vertically, horizontally, and longitudinally due to an earthquake or rainstorm, the joint cover will be damaged. As a result, 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 configuration, as shown in FIG. 6, the joint is covered by a pair of cover plates a and b whose inner ends are overlapped, and connecting bodies c and c that fix the base ends of the cover plates are oscillated. In order to enable the cover plate to move in accordance with relative rocking between the buildings, and to support the cover plates a and b, the holding member d is cantilevered along the inner surface of one cover plate a. The inner and outer surfaces of the other cover plate b are held between the holding member d and one cover plate a at the inner end thereof.

Therefore, only the inner end portion of the other cover plate b is held, and for example, when one cover plate a swings, the swinging force is transferred only by the other cover plate b. The signal is transmitted to the connecting body, etc. For this reason, since the cover plates a and b are usually formed of thin steel plates, as shown in FIG. Force is applied, causing bending strain in this part. Further, when one of the cover plates a is strongly pressed in a state where the building is not shaking, the cover plate a slightly rotates around the connecting body c,
The other cover plate b is bent and undergoes similar plastic deformation.

The present invention aims to improve the above-mentioned structure and prevent deformation of the cover plate, and includes a pair of fixed bodies fixed to mutual wall surfaces of adjacent buildings, and both fixed bodies. a first connecting arm projecting inwardly from one of the connecting bodies to the other connecting body; a second connecting arm that is fitted so as to be slidable along the first connecting arm, and whose end portion is allowed to move relative to the first connecting arm in a direction away from the second connecting arm; A pair of cover plates having fixed ends and a pair of cover plates having free ends overlapped between the two connecting bodies to cover the joints at the front parts of the two connecting arms, and the interlocking of the connecting bodies etc. are controlled by the first and second connecting bodies. This is caused by the arm.

An embodiment of the present invention will be described with reference to the accompanying drawings.
