DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an expansion joint which connects buildings and moves freely.

[0002]

2. Description of the Related Art Conventionally, a floor plate such as a steel plate is installed on a floor of an expansion section between building bodies in order to cope with a constant use such as walking and deformation in the event of an earthquake. Is generally fixed to one side with a bolt or the like, and the other is configured to be slidable on the skeleton in a free state.

[0003]

The above-mentioned conventional expansion joint functions with respect to horizontal displacement against deformation between buildings due to an earthquake, but has no followability with respect to vertical displacement. May cause damage.
In addition, the floor plate of the expansion joint is placed directly on the floor, and a step corresponding to the plate thickness occurs on the floor.

The present invention has been proposed in view of the above-mentioned problems of the prior art, and its object is to function smoothly in response to both horizontal and vertical displacements and to provide a step on the floor. It is to provide an expansion joint that does not occur.

[0005]

In order to achieve the above object, a horizontal and vertical movable expansion joint according to the present invention has a spherical portion provided at one end of a slide plate fixed to one building frame. A slide plate in a slide roller support portion which is rotatably fitted between an upper hinge holding member and a lower hinge support member, and the other end of which is fixed to the other building frame provided with a space from the frame. A sliding mat is slidably mounted on the storage lower member, a flexible mat is laid on an expansion portion of a slide plate in an intermediate portion of the two frames, and the mat and the upper hinge pressing member of the one frame and The slide roller supporting portion of the other body is in contact with a slide plate storage upper member via an inclined surface.

[0006]

Since the present invention is configured as described above,
For a normal load, the expansion portion is supported by the slide plate via a mat, by a hinge portion provided on one skeleton side, and a slide plate storage lower member provided on the other skeleton side. Things.

[0007] With respect to horizontal displacement, the contact surface between the upper slide plate storage upper member on the other skeleton side and the mat on the slide plate is formed as an inclined surface, so that the mat can be pushed up to be smooth. To work. In addition, with respect to vertical displacement, the spherical portion at the end of the slide plate hinges between the upper hinge holding member and the lower hinge supporting member of the one skeleton, thereby smoothly causing no damage. To work.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. A is one of the frames, B is the other frame disposed at an interval from the frame A, and 1 is a horizontal slide plate disposed between the frames A and B, which are usually opposed to each other. Between the floor and the floor, and between the floor and the wall.

A spherical portion 2 is provided at one end of the slide plate 1, and an upper hinge pressing member 5 provided on a hinge side fitting 4 fixed to one of the frames A via an anchor bar 3 and a lower portion. An end portion rotatably fitted to the hinge support member 6 and extending on the other skeleton B is fitted between upper and lower slide plate storage members 7 and 8 fixed to the skeleton B, and a tip end portion is provided. The bent piece 1a is slidably mounted on the lower slide storage member 8. The load can be smoothly transmitted by providing a projection 7a, which comes into contact with the slide plate 1 from the upper slide plate storage member 7 as necessary.

The relative sliding can be smoothly performed by rounding the member contact surface. In the figure, reference numeral 9 denotes a roller side T-shaped joint, 10 denotes an anchor bar to which the joint 9 is welded, 11 denotes stuffing mortar, 12 denotes joint caulking, 1
Reference numeral 3 denotes a weld between the anchor bar 10 and the connector.

A mat 14 made of rubber, carpet, or the like is laid between the frames A and B of the horizontal slide plate 1. Both ends of the mat 14 and the upper slide plate storage member 7 and the upper hinge holding member are provided. The contact portion with 5 is formed on an inclined surface. Since the illustrated embodiment is configured as described above, for the horizontal displacement indicated by the arrow X, the mat 14 comes into contact with the upper slide plate storage member 7 and the upper hinge holding member 5 at an inclined surface. As a result, it is pushed up when shrinking, and functions smoothly without causing damage.

In addition, with respect to the vertical displacement indicated by the arrow Y, the end spherical portion 2 of the slide plate 1 hinges between the upper hinge pressing member 5 and the lower hinge supporting member 6 to cause damage. It works smoothly without inviting. At this time, the upper slide plate storage member 7 is made to be able to follow the displacement.

[0013]

As described above, according to the present invention, the spherical portion provided at one end of the slide plate disposed between the building frames located at an interval is fixed to the upper portion fixed to one of the frames. By being rotatably fitted between the hinge holding member and the lower hinge supporting member, the hinge of the spherical portion can be rotated with respect to vertical displacement, and the expansion joint functions without being damaged.

The other end of the slide plate is slidably mounted on a slide plate storage lower member fixed to the other body, and a flexible mat is laid on an expansion portion of the slide plate. Since the mat and the upper slide storage material and the upper hinge holding material are in contact with each other via the inclined surface, the mat is pushed up when contracted against horizontal displacement, so that the expansion joint is smoothly damaged without being damaged. To work. Further, the above structure eliminates a step on the floor surface due to expansion.
