Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an expansion joint that can close a gap between adjacent building structures to prevent intrusion of rainwater, and can absorb a change in the structure due to an earthquake or the like.
[0002]
[Prior art and problems to be solved by the invention]
As this type of expansion joint, for example, in Japanese Patent Application Laid-Open No. H8-42005, etc., as shown in a partial perspective view in FIG. The support member body 611 in which the groove engaging portion 611c for engaging the connector and the engaging portion 611e for engaging the waterproof sheet 6S are arranged in parallel, and the body engaging portion 612a that engages with the groove engaging portion 611c. The receiving portion 612c formed at one end is engaged with a piece-shaped connector 612 provided with a bolt insertion hole 612e, and the connector 612 is projected into a housing gap at a predetermined position of the support member body 611. An expansion joint is disclosed in which a connecting member for connecting a cover body to 612 is connected.
[0003]
The expansion joint is configured to variably connect a connecting member to both supporting members fixed to both housings, and to cover the housing gap by attaching a cover body via the connecting members. The long support member main body 611 and the piece-like connector 612 are engaged, and the support member main body 611 is fixed to the housing, and the groove-like locking for the connector 612 formed at the end of the housing gap side. Since the connector 612 is engaged with the portion 611c, there is an effect that the engagement is simple and reliable.
[0004]
However, when the above-mentioned expansion joints move in the longitudinal direction of the gap between the adjacent bodies (this direction is also referred to as “Y direction” hereinafter), this expansion joint is caused by the sliding movement between the support member 61 and the connector 612. However, when they fluctuate in the gap width direction of the housing (this direction is also referred to as “X direction” hereinafter), there is a problem that this cannot be absorbed.
[0005]
Therefore, as an expansion joint that can absorb an adjacent housing in any of the Y and X directions, Japanese Patent Application Laid-Open No. 9-4070 discloses a housing 7A as shown in a partial perspective view in FIG. A long fixing member 71 having an engagement groove 71b having a C-shaped cross section is disposed along the longitudinal direction of the housing, that is, the Y direction, and the tip portion standing from the joint surface 75a is a bulged engagement protrusion 75c. The member 75 is slidably connected to the fixing member 71 by engaging the engaging groove 71b and the engaging protrusion 75c, and the bottom plate 73a is brought into contact with the joining surface 75a so that the long holder 73 is passed over the housing gap. In other words, an inverted W-shaped elastic clip 76 that is disposed along the X direction and has a flat intermediate surface on the upper surface of the bottom plate 73a is disposed on the bottom plate 73a of the long holder 73 along the longitudinal direction. Long hole A bolt 78 is passed through 3d, and a long holder 73 is slidably connected to the joining surface 75a of the support member 75 via a resilient clip 76, and a cover body is fitted on the long holder 73. An expansion joint is disclosed.
[0006]
According to the expansion joint having such a configuration, when both the housings 7A and 7B are changed in the Y direction, they are absorbed by the Y direction slide between the fixing member 71 and the support member 75 and are changed in the X direction. In this case, this can be absorbed by the X-direction slide between the support member 75 and the long holder 73.
However, in the expansion joint, the X-direction slide range between the support member 75 and the long holder 73 is restricted by the length of the long hole 73d, and the long hole 73d must be formed in the first place, so that productivity is improved. There has been a problem of lowering. In addition, at the stage of construction, there was also the complexity that had to be fastened using bolts and nuts.
[0007]
Therefore, in order to solve the problem of the conventional expansion join, the present invention can follow any change in the Y direction and the X direction of the adjacent housing, and can follow it. It is intended to provide an expansion joint having a larger range than the conventional one, yet having high productivity and preferably excellent workability.
[0008]
[Means for Solving the Problems]
In order to solve such a problem, the present invention provides an expansion joint for connecting gaps between adjacent casings, a rail receiving material disposed and fixed on at least one side end face of the casing, and a casing clearance between the rail receiving materials. A slide pedestal portion that is slidably connected in the longitudinal direction (Y direction) , and a slide holder that is attached to the slide pedestal portion and that has a rail receiving portion on the upper surface portion in a direction intersecting the rail receiving material; A cover holder disposed obliquely in a vertical vertical direction (Z direction) with respect to the end face of the casing and slidably connected to a rail receiving portion of the slide holder in a casing gap width direction (X direction) ; a resilient clip which can automatically adjust the change in the mounting angle of the slide base portion and the slide holder by the gap width direction (X direction) slides, the mosquito To form the expansion joint configuration comprising a fitted and a cover material over the holder as main constituent.
[0009]
That is, according to the present invention, a slide pedestal portion that slides a rail receiving material and a cover holder are connected via a slide holder, and a rail receiving portion is provided on the upper surface portion of the slide holder. It is possible to eliminate the need to provide a long hole on the bottom surface of the cover holder, which makes it possible to slide freely along the rail receiving material and the rail receiving portion, and the range that can be followed is regulated by the length of the long hole. Compared with the conventional case, the followability of the expansion joint can be dramatically improved. Further, it is not necessary to provide a long hole on the bottom surface of the cover holder, and productivity can be increased.
[0010]
In the above configuration, the slide pedestal portion is connected to the rail receiving material so as to be slidable in the longitudinal direction (Y direction) of the housing gap and to be rotatable in the vertical vertical direction (Z direction). The slide pedestal portion has a round bulge protrusion that protrudes in the horizontal direction on one side of the pedestal body, and this protrusion is inserted into the occlusal groove of the rail receiving material. It is preferable to have a configuration in which it is slidable in the longitudinal direction (Y direction) and pivotable in the vertical vertical direction (Z direction).
