摘要： PROBLEM TO BE SOLVED: To reduce a working space and make the height lower by installing a precast beam on a precast column erected at both sides of a road bed and laying a precast slab thereon and constructing a rigid-framed elevated bridge. SOLUTION: A number of reinforcement insertion holes are formed in a columnar crust body and many hoops are embedded circumferentially in a half-precast column 3. Reinforcements are inserted in the reinforcement insertion holes and connected to anchor reinforcements anchored in a foundation 2 through joints, and further, concrete is placed in the hollow inside. Beam reinforcements are connected to each other by joints to connect half-precast beams 5. A half-precast slab 7 is laid on the half-precast beam 5. The half- precast column 3, the half-precast beam 5, and the half-precast slab 7 are fabricated in a factory in advance. Upper reinforcements are arranged in the half- precast beam 5 and the half-precast slab 7 and cast-in-place concrete is placed. In this way, the construction period of time can be reduced and labor can be saved.

摘要： PROBLEM TO BE SOLVED: To provide a rigid-frame viaduct construction method capable of shortening construction period, reducing human labor required, allowing selection of the shape of precast members and being adapted to any construction conditions.
SOLUTION: The rigid-frame viaduct construction method comprises the steps of constructing precast pillars on both sides of a traffic base course, constructing a precast beam on the precast pillars and further constructing a precast slab on the precast beam to place a traffic base course in service.

摘要： PURPOSE: To prevent the breakage of an RFP rod by providing a sliding groove in the axial direction of the outer periphery of a tube member holding the RFP rod, and providing a projection on the inner periphery of an outer tube storing the tube member. CONSTITUTION: A fixing device is provided with a tube member 10 holding an FRP rod 13 and an outer tube 20 slidably holding the tube member 10, and the rod 13 is held on the tube member 10 by a wedge 12. The rod 13 is fixed to the tube member 10 through a pressure support plate 30 installed on a structure and through the inner hole of the outer tube 20, and the rod 13 is fixed on the pressure support plate 30. Initial tension is applied to the other end side of the rod 13 to fix the rod 13, and the projection 21 of the outer tube 20 is supported on the end section of a sliding groove 11. When an excessive load is applied to the structure, the projection 21 is pulled into the groove 11 before the tension applied to the rod 13 reaches the breaking tension, and the fixed end section of the rod 13 is moved in the tension direction. The tension applied to the rod 13 is reduced, and the rod 13 can be fixed by a sliding mechanism without being ruptured.

摘要： PROBLEM TO BE SOLVED: To prevent buckling of a main reinforcement and shearing dislocation of a skeleton base part by providing a shape steel along a right-angled direction to a bridge axis outside a steel plate, anchoring the shape steel to a footing by an anchor reinforcement, and cutting connection between the steel plate and shape steel. SOLUTION: An H-shape steel 3 is provided along a right-angled direction to a bridge axis outside of a lining steel plate 2 at a base part of a skeleton 1a of a bridge pier 1. The H-shape steel 3 is oriented so that its flange part 3a points vertically and that its web part 3b points horizontally. An anchor reinforcement 4 is anchored to a footing 1c, and its upper end pierces the web part 3b of the H-shape steel 3 to cramp-fix the H-shape steel 3 by a nut 4a. Cushioning material 5 is clamped between the lining steel plate 2 and the flange part 3a of the H-shape steel 3 to cut connection between the steel plate 2 and H-shape steel 3 so that the flexure bearing force after reinforcement of the bridge pier 1 does not change from that before reinforcement. Buckling of a main reinforcement and shearing dislocation of the skeleton base part are thereby prevented without opening a through hole in the skeleton 1a or reinforcing the footing.
