THE SELF POSITIONING JOINT STRUCTURE BETWEEN PRECAST STEEL-CONCRETE COMPOSITE COLUMN AND PRECAST STEEL-CONCRETE COMPOSITE BEAM

摘要

The present invention relates to a self positioning joint structure between precast SRC column and precast SRC beam, comprising: a precast SRC beam (100) including a beam steel frame (110) and beam concrete (150) surrounding the beam steel frame (110); a precast SRC column (200) including a column steel frame (210) and a column concrete (250) surrounding the column steel frame (210); a beam plate (130) coupled to an end of beam steel frame (110) formed with a setting bolt inserting hole (132) on a lower portion; an anchorage bar (270) installed by penetrating the column steel frame (210) in a tilted U-shape, and buried on the column concrete (250); a column plate (230) engaging to an end of the anchorage bar (270) formed with a male screw thread with an insert nut (260) formed with a female screw thread installed by partial insertion on an outer surface of the column concrete (250); and a setting bolt (SB) installed in the lower portion of the column plate (230) by exposing externally, wherein the setting bolt (SB) is inserted to the setting bolt inserting hole (132) when the beam plate (130) moves downwards with contact on the column plate (230), allowing self positioning.
