ARCH-SHAPED PRECAST PANEL FOR BUILDING ARCH-TYPE SLAB AND CONSTRUCTION METHOD OF ARCH-SHAPED SLAB BRIDGE USING THE PANEL

摘要

An arch-type precast panel for building an arch-type slab and a construction method for an arch-shaped slab bridge using the same are provided to improve structural stability and constructional convenience thereof. An arch-type precast panel(50) for building an arch-type slab comprises a plurality of prestressed synthetic beams(20) mounted to an upper part of a pier to form width of a bridge. A unit arch-type precast panel is mounted to upper parts of lower concrete casings(23) of the prestressed synthetic beam. A mortar casting part(42) is formed between the arch-type precast panel and the prestressed synthetic beam. Concrete(14) is wholly cast to form the slab, so that the arch-type precast panel and the slab are integrated with each other. A construction method for an arch-shaped slab bridge using the panel comprises the steps of mounting a plurality of the prestressed synthetic beams by forming a connection part, forming the mortar cast part between a vertical part(54) of the arch-type precast panel and a web(22) of the prestressed synthetic beam, casting slab concrete, and mounting a curbstone(13) to both ends of width of the bridge.
