ることは少ない。When the concrete girder is placed on the placing portion of the abutment, an expansion joint is installed between the facing surfaces of the concrete girder and the abutment. The expansion joint is usually installed between the road surfaces of the concrete girder and the road surface of the abutment, but is rarely installed between the ground cover of the concrete girder and the ground cover of the abutment.

え、地覆部の位置や形状がまちまちで曲げ加工が困難な
ため、路面部の対向面間と地覆部の対向面間のものを一
体に製作するのが大変に困難であることによる。The expansion joints are installed on the facing surfaces of the road surface of the concrete girder and the road surface of the abutment, and are not installed between the facing ground coverings in addition to the bridge itself being large in size. This is because it is very difficult to integrally fabricate between the facing surfaces of the road surface portion and the facing surface of the ground covering portion because the positions and shapes are different and bending is difficult.

る。However, when a padding material formed of concrete or the like is placed between the ground cover of the concrete girder and the ground cover of the abutment, expansion and contraction between them are considered. Even if a gap is provided, when the concrete girder or abutment moves unexpectedly such as when an earthquake occurs, when each ground cover collides with this padding material or when the padding material is not installed. Has a problem that the ground coverings of concrete girders and abutments of abutments are damaged due to the phenomenon that the ground coverings of the opposite sides collide with each other.

A concrete girder is placed on an abutment, and a steel hollow cylinder is fixed to each of the facing surfaces of the facing portions of the concrete girder and the abutment, and the steel adjacent to the steel hollow cylinder is fixed. One or two or more steel hollow cylinders having different outer and inner circumferential dimensions so that they can be fitted to each other, are fitted and continuous to each other, and the respective steel hollow cylinders are fitted together. Characterized in that the parts are connected with a coupling tool except for the fitting part of the steel hollow cylindrical body which is fitted to one steel hollow cylindrical body fixed to the respective ground coverings of the concrete girder and abutment Construction method of expansion joint for ground cover.

法。5. A concrete girder is placed on an abutment, and a steel hollow cylinder is fixed to each of the facing surfaces of the ground cover facing the concrete girder using a fitting, and the steel hollow cylinder is also fixed. The outer and inner circumferences of the adjacent hollow steel cylinders have different circumferential dimensions so that they can be fitted to each other.
Alternatively, two or more steel hollow cylinders are fitted and connected continuously, and the fitting portion of each steel hollow cylinder is fitted to one steel hollow cylinder fixed to the abutment and the concrete girder cover. A method for constructing an expansion joint for a ground cover, which is characterized by joining with a joining tool having a strength lower than that of the steel hollow cylinder except for a fitting portion with a hollow steel cylinder to be fitted.
