- PC PC the rigid connection structure between precast concrete column and precast concrete beam the construction method of rigid connection structure using the same

摘要

The present invention is applicable to a PC column including a column steel frame 110 exposed between a column top concrete 130 and a column lower concrete 140 and a column bracket 120 horizontally installed on an outer surface of the column steel frame 110 (100); A PC beam (200) comprising a beam concrete (232) and a beam steel frame (210) exposed at the upper end of the beam concrete; A column lower plate 162 installed below the column steel frame 110; A column top plate (166) installed on the column lower concrete (140) and having an end exposed to the outside of the column lower concrete (140); A filler plate 164 installed between the column lower plate 162 and the column upper plate 166; , / RTI A column steel joint plate 400 is installed under the column concrete 130 and the upper part of the column steel joint 110 is joined to the column steel joint plate 400, The lower end of the beam concrete 232 is mounted on the end of the column lower plate 162 and the column bracket 120 and the support frame 210 are coupled using a plate, The column lower plate 162 and the column upper plate 166 and the filler plate 164 are of the same size and the filler plate 164 is formed of a columnar reinforcing bar protruding to the lower portion of the column lower plate 162 And a column bottom reinforcing bar 170 protruding upward from the upper portion of the column upper plate 166. The column lower reinforcing bar 170 is formed so as not to interfere with the center reinforcing bar 172 and the center line Characterized by being bent, An inner bolt (IR) protrudes upwardly from the column top plate 166, The inner bolt IR penetrates the filler plate 164 and is fastened to the column lower plate 162 so that the inner bolt IR penetrates through the column upper plate 166 and the filler plate 164, The contact surfaces between the plates 162 are prevented from being separated from each other, and the vertical and horizontal loads are transmitted and the column top plate 166, the filler plate 164, and the column bottom plate 162 are generated The displacement is reduced, The column bracket 120, the support beam 210, and the column steel beam 110 are pushed together when the concrete (not shown) is poured to realize a strong joint. The steel-concrete hybrid PC And a method of constructing a rigid joint structure using the same.
