END PART STRUCTURE OF BRIDGE CONTAINING SEMI-INTEGRAL ABUTMENT USING STEEL AND CONSTRUCTION METHOD THEREOF

摘要

The present invention relates to an end part structure of a bridge containing semi-integral abutment using steel. The end part structure of the present invention includes: an abutment (10); a connecting block (20) made of box-type steel and provided at the upper portion of the abutment (10); a bridge support (30) provided at the upper portion of the abutment (10); and a girder (40) made of box-type steel and fixed to the connecting block (20). The method of constructing an end part structure of a bridge containing semi-integral abutment using steel of the present invention includes: a first step of constructing the abutment (10); a second step of placing the girder (40) made of box-type steel on the abutment (10) and installing the connecting block (20) made of box-type steel receiving and fixating the girder (40); a third step of pouring concrete (C) to the inside of the girder (40) and the connecting block (20) and simultaneously pouring concrete into a slab (50); a fourth step of injecting the back filling material; and a fifth step of pouring concrete to a connecting slab (52). Therefore, the connecting block has increased strength and improved workability without steel reinforcement. In addition to this, the present invention facilitates carriage, provides an efficient construction method, and provides an excellent appearance by pouring concrete after installing the connecting block and the girder.
