摘要： PROBLEM TO BE SOLVED: To provide a composite hollow structure of a column head part or a girder end part of PC bridge capable of shortening a construction term owing to the large reduction of quantity of concrete and the number of reinforcing bars to be used, improving earthquake-resistant performance owing to the reduction of its dead weight, and reducing necessity for earthquake-proof reinforcement. SOLUTION: In this column head part 2 of continuous girder type, a horizontal girder 4 is composed of a floor slab part 10, a bottom slab part 11, and a pair of right and left webs 12 in the direction of right angle to a bridge end, a hollow part 13 passing through in the direction of bridge axis is formed, and the horizontal girder 4 is formed into a hollow structure. A pair of steel pipe struts 20 filled with concrete and having a truncated chevron shape in a front view are arranged inside the hollow part 13, an upper part is fixed on a lower face of the floor slab part 10, and a lower part is buried into the bottom slab part 11 to connect them rigidly. Shaft force and bending action force are transmitted to a support 6, and a reinforcing steel member 21 connected with the pair of right and left struts 20 resists the action force for pushing and extending the bottom slab part 11 to the right and left to hold cross section of the column head part 2 properly.

SOLUTION: In this column head part 2 of rigid frame type, a horizontal girder 4 is composed of a floor slab part 10, a bottom slab part 11, and a pair of right and left webs 12 in the direction of right angle to a bridge end, a hollow part 13 passing through in the direction of bridge axis is formed, the horizontal girder 4 is formed into a hollow structure, and a pair of right and left tensile force transmission reinforcing steel plates 20 having a right-angled triangle shape when viewed in front are arranged inside the hollow part 13 and are fixed on an upper face of the bottom slab part 11 and an inner face of the web 12. A lower part side of the tensile force transmission reinforcing steel plate 20 is fixed on fixing reinforcing bars 7 from a bridge pier 1, and tensile force of the fixing reinforcing bar 7 is transmitted to the web 12 to hold the rigidly connected condition of the column head part 2.
