Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to an improvement of a joint cover device for covering joints of adjacent building structures.

<Prior Art> As this kind of joint cover device, there is a simple structure in which the base portion is fixed to each building structure, but with such a structure, the building structures are vertically, horizontally, and horizontally caused by an earthquake or a storm. When shaken in the front-back direction, a crack may be generated in the attachment base portion of the joint cover device, which may damage the wall surface of the building structure in some cases. In addition, the wall surfaces of the building structure may not necessarily be in the same plane or in a normal relationship.

Therefore, as a countermeasure, a joint cover device was devised in Japanese Utility Model Laid-Open No. 60-11911 to absorb the relative swing between the building structures and eliminate the above-mentioned defects.

This structure covers joints y between building structures x and x, and plate springs are provided between supporting members fixed to both parallel wall surfaces of adjacent building structures. A cover plate that covers the joint between both wall surfaces is connected to the center of the spring, and the action of the plate spring causes the cover plate to follow the mutual movement of the building structures.

On the other hand, a spring in which a leaf spring is used instead of a leaf spring is also proposed in Japanese Utility Model Laid-Open No. 62-27911 and Japanese Laid-Open Patent Publication No. 62-148741.

<Problems to be Solved by the Invention> By the way, in each of the above-described conventional configurations, each member is sequentially fixed in the field work, and there is no cohesion.
There was a problem that the construction was troublesome.

Further, even if it has the following ability, there is a problem that it cannot sufficiently respond when the adjacent building structures relatively move along the joint.

INDUSTRIAL APPLICABILITY The present invention enables relative movement of building structures in three-dimensional directions, absorbs relative swings between building structures caused by an earthquake or storm, and prevents the relationship between the wall surfaces of building structures. It is an object of the present invention to provide a joint cover device that can cover joints evenly even if they are distorted and that is easy to construct.

<Means for Solving Problems> The present invention is to fix a fixed body in which fitting grooves that open in either the inside or outside direction are formed on both parallel wall surfaces of adjacent building structures through joints. A connecting support piece having a fitting portion that is tightly fitted tightly in the fitting groove of one fixed body, and a fitting portion that is loosely slidably fitted in the fitting groove of the other fixed body. The connecting support pieces are arranged on the left and right sides, and the connecting rods are loosely inserted and passed between the left and right connecting support piece pairs, the attachment tongue pieces are fixed to both ends of the connecting rods, and the connecting rods are connected to the connecting rods. A holding device is constructed by attaching a position-holding ridge that urges the support piece in either the inward or outward direction, and the holding device is arranged by attaching a pair of connecting support pieces to a fixed body pair at appropriate intervals. And a cover plate is attached on each holding device to fix the inside of both ends to the mounting tongue. It is a joint cover device.

<Operation> As described above, the holding device is unitized and assembled in advance.

Therefore, in order to mount the joint cover device, the fixed body pair is fixed to both parallel wall surfaces of the building structure, and the holding device is fixed to the fixed body pair at appropriate intervals. At this time, one fitting portion of the holding device is fixed to one fixed body, and the other fitting portion is slidable with respect to the other fixed body along the joint direction. Then, the cover plate is attached onto the holding device and fixed to the mounting tongue, whereby the assembling is completed.

In this assembled state, the cover plates are fixed to both ends of the connecting rod, and are held on the connecting support piece, that is, the fixed body side via the connecting rod. At this time, since the cover plate is urged outwards on both sides or urged toward the center due to the position-holding springs attached to the connecting rods, the balance between the urging forces on both sides always keeps the center of the fixed body pair. Will be held in position.

And when the adjacent building structure moves relative to each other along the joint, since the fitting portion is slidably connected to one fixed body, the holding device and the cover plate are relative to the one fixed body. It slides and its relative movement is allowed without difficulty.

In such a structure, when the adjacent building structures relatively move in the adjacent direction, the cover plate has the connecting rod supported by the connecting support piece so as to be slidable along the wall surface. It is possible to move along.

Further, by the position-holding springs attached to both the wall connecting rods, they are urged outward on both sides or toward the center. Therefore, the connecting rod is biased to the left and right even positions with respect to the connecting support piece by the spring action, and therefore, the cover plate is on both sides of the joint even when the building relatively moves in the left and right direction.
It will be covered evenly.

Further, when the building structure moves in the front-rear direction, the connecting rod tilts with respect to the connecting support piece to incline the cover plate, and thereby the back-and-forth movement of the building structure can be followed. It will be.
