Pier Cap Installation Structure Using Precast Concrete Shell And Construction Method Thereof

The present invention is exposed to the upper pole jucheolgeun 110 in peer cap construction method is constructed on top of the pier pillar 100 of the bridge (1) the angle of intersection pole 100 is to ensure the development length of the step in the upper a couple of pole construction phase by pouring concrete for the construction of bridge piers pole 100 mounted to form a jaw (120); (2) reinforcement with a plurality of peer cap shear reinforcement 350 inside the lower hollow (212) so that the precast concrete shell 200 produced linearity and a plurality of peer to the upper portion of the precast concrete shell (200) but the reinforcement cap jucheolgeun 300 peer cap reinforcement forming the precast concrete shell 200 inside the pillar jucheolgeun 110 and that does not interfere any of the reinforcement is not reinforcement mubae root (500); (3) the pre-cast the pillar jucheolgeun 110, a concrete shell 200 sikidoe mounted on the pillar 100 through the pre-cast concrete shell to mount so as to pass through the hollow (212); 4 concreting step of pouring concrete in the precast concrete shell (200); Doedoe configuration including,; and, (5) a curing step of curing the concrete placing The precast concrete shell 200 (1) columns to be produced, with or 1, first line in the plant than the pillar construction phase and the construction phase the lower plate 210, a hollow 212 is formed; and the two front vertical plate 220; And two side risers (230); as a box-like is configured integrally as a whole and formed with a hollow open top 212 to the bottom, Ring plate 240 of the circle to form a hollow 212 of the bottom plate 210; To be installed in the lower plate 210, a plurality of concrete shell bottom reinforcement 250 is joined to the outer peripheral surface of the ring plate 240; The front vertical plate 220 and the side surface can be a plurality of concrete shell vertical plate is the concrete shell, the lower reinforcement (250) is extended to be installed in the unit 230 over the bent or that the joint and the concrete shell, the lower reinforcement (250) perpendicular reinforced 260; The concrete shell bottom reinforcement (250) or between concrete shell neukgeun 270 for coupling between the concrete shell vertical reinforcement 260 integrally; And the lower plate 210 and the front vertical plate 220 and the side surface can concrete coating thickness from the as forming the exterior of the vertical plate 230 of concrete shell bottom reinforcement 250 and the concrete shell, the vertical reinforcement 260, top and bottom or left and right the peer service cap mounting structure and methods for their construction using precast concrete shell, characterized in that consisting of; maintain and is of shell construction concrete. In addition, further to the above (1), the pillar after the construction phase through jaw 120 above (1`) steel bracket installation step of mounting a steel bracket (400) or contain further configured, (1) Column construction stage is installed peer cap using a pre-cast concrete shell, characterized in that further form a concrete bracket 130 extends to the mounting projection 120 of the pier pillar 100 to the outer structure and It provides a construction method thereof. Peer using precast concrete shell provides a cap mounting structure and methods for their construction.
