される伸縮ジョイントに関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an expansion joint attached to a road bridge joint of a highway or the like, and more specifically, repairs such as replacement of a joint due to deterioration of the joint near the expansion joint attached to the road bridge joint. Regarding expansion joints used during construction work or joint installation work for new road bridge joints.

る。2. Description of the Related Art The expansion joint replacement work of a road bridge joint is carried out by breaking down the concrete around the joint attached to the joint with an equipment such as an excavator to remove the joint, and each joint section is L-shaped. A notch is cut into it, a new joint is installed, and concrete is poured into it for repair.

と、コンクリート（床板）掘削切欠部の凹凸状の取付面
および切崩し角部との間に不安定な空間ができる。During the excavation process in which the concrete (floor plate) around the joint is cut into an L-shaped section, the protruding corners of the L-shaped cutout section are inevitably broken into large irregularities over the mounting surface during the excavation procedure. As a result, when installing a new joint, an unstable space is created between the rigid base plate surface of the joint and the uneven mounting surface of the concrete (floor plate) excavation notch and the cut corner.

れて各工事を終えていた。Since concrete to be poured in when newly installed or repaired is driven from above and outside of the joint, it is difficult to introduce it into the space part of the contact surface because it is obstructed by the base plate and it is a state where space is created. It was fixed at and finished each construction.

あった。For this reason, the joint portion of the road bridge joint after completion of construction is hit by repeated running heavy pressure of an automobile or the like, and the fixed supporting force of the joint by the floor plate is weakened due to the space of the installation surface, which causes vertical vibration. There is a risk of reaching
The strength of the joint of the joint to the floor plate was weak.

よる高さ調整が困難であった。In addition, when installing a joint to a road bridge joint in a new construction or repair work, when installing the joint on the floor plate or bridge girder and driving the concrete into the joint, the fresh concrete flows down between the joints of the floor plate and the bridge girder to block it. In addition, there is a risk that the joint may cross, and it is difficult to adjust the height of the joint due to the transverse gradient.

Fresh concrete should be smoothly and accurately introduced into the notched surface of the floor plate or the space created between the floor plate (bridge girder) and the joint base plate, and driven into the gap between the floor plates to absorb the extensional displacement due to temperature change. It is to prevent the concrete from flowing into the delusion and also to facilitate the height adjustment of the joint to the road surface.

容易にできることに特徴がある。As described above, the joint of the road bridge seam portion of the present invention has the following construction.
With the through holes on the outer sides of the base plates and the tongue plate on the lower surface of the inner side of the pair of joint members arranged so as not to get on each other's floor plates, the joint members are sewn into the joint member with the through holes on the outer sides of the base plates. Since it can be extended and extended in series up and down with the base plate sandwiched on the outside, the raw concrete is tightly filled through the through hole to the space formed between the joint member and the floor plate, and the supporting force for the joint member is increased. It is also characterized in that it is easy to crush the space that weakens the pressure resistance into a series with concrete.
