The invention discloses a prefabricated bridge
pier steel bar connection manner and a construction method thereof. A
steel bar embedded in a
precast concrete component and a grouting sleeve are included, a steel
chisel strip is arranged on the inner wall of the grouting sleeve along the circumference, one end of the grouting sleeve is provided with a grouting hole, the other end of the grouting sleeve is provided with a
slurry discharging hole, a limit baffle is arranged at the center of the sleeve,
rubber ring plugs are arranged on ports of the two ends, the steel
chisel strip is welded to the inner wall of the sleeve, the surface of the
steel bar is in a concave-convex shape, and the shape of a joint of the steel
chisel strip is matched with the steel bar to form mechanical overlap. In the installation process of a prefabricated bridge
pier, after a prefabricated component is straightened and positioned, the other end of the steel bar is inserted into the grouting sleeve, as the joint of the steel chisel strip is in mechanical connection with the steel bar, the steel bar is not easily pulled out, and at the time, ordinary
mortar is poured from the grouting hole. According to theprefabricated bridge
pier steel bar connection manner and the construction method, the steel bar and the grouting sleeve have mechanical
biting force, the steel bar is not easy to be pulled out, certain tensile and
compressive resistance can be provided, then the ordinary
mortar is poured into the sleeve, and the construction accuracy and
quality assurance are better.
