BICYCLE BRIDGE HAVING LONG SPAN CONNECTION AS USING PRECAST CONCRETE PANELS

摘要

PURPOSE: A bicycle bridge for a long span connection using precast concrete panels is provided to be rapidly installed, to reduce costs for manufacturing and constructing, and to connect panels by a long span. CONSTITUTION: A bicycle bridge for a long span connection using precast concrete panels comprises a concrete panel(10), multiple PHC(Pre stressed High-strength Concrete) piles(20), a shear reinforcement, a first I-beam(40), a second I-beam(43), a wooden material(44), and a PS(Pre Stressed) steel bar. The concrete panel is inserted into the head of the PHC piles through a cap unit. The PHC piles are piled in the underground of a river at regular intervals. The shear reinforcement is accommodated in the cap unit, and enhances the shear stress of a panel body(11) and the PHC piles. The first I-beam is regularly arranged between the panel bodies which are installed at the head of the PHC piles. The second I-beam is longitudinally connected to the first I-beams in order to maintain the interval between the first I-beams and to enhance a supporting force. The wooden material is laterally or longitudinally connected to the top of the first and second I-beams. The PS steel bar is inserted into the accommodating pipe(16) of the concrete panel, and tenses the first I-beams along the direction of the panel body.
