PC PC the rigid connection structure between the upper precast concrete column and the lower precast concrete column and the rigid connection structure of the precast concrete girder using the same

摘要

The present invention pillar concrete 230; A lower pillar plate 270 installed on the pillar concrete 230; And a plurality of lower pillar reinforcing bars 210 embedded in the pillar concrete 230 so as to maintain a concrete coating thickness and being vertically reinforced and exposed through the lower pillar plate 270. Lower PC column 200; Pillar concrete 130; An upper pillar plate 170 installed below the pillar concrete 130; And a plurality of upper pillar reinforcement 110 embedded in the pillar concrete 130 to maintain the concrete coating thickness and vertically reinforcement and having a lower end exposed through the upper pillar plate 170. Upper PC column 100; Consists of including The pillar concrete 130 of the portion where the upper pillar reinforcement 110 is exposed is boxed out without contacting the upper pillar plate 170, so that an upper end of the lower pillar reinforcement 210 is the upper pillar plate ( When exposed through the 170, the box out 150 provides a strong joint coupling structure between the upper and lower PC columns, characterized in that the reinforcement of the upper column reinforcement 110 and the lower column reinforcement 210 is possible. . In addition, pillar concrete 230; A lower pillar plate 270 installed on the pillar concrete 230; And a plurality of lower pillar reinforcing bars 210 embedded in the pillar concrete 230 so as to maintain a concrete coating thickness and being vertically reinforced and exposed through the lower pillar plate 270. Lower PC column 200; Pillar concrete 130; An upper pillar plate 170 installed below the pillar concrete 130; And a plurality of upper pillar reinforcement 110 embedded in the pillar concrete 130 to maintain the concrete coating thickness and being vertically reinforced and having a lower end exposed to the lower portion of the pillar concrete 130. Pillar 100; Consists of including The pillar concrete 130 at the portion where the upper pillar reinforcement 110 is exposed is boxed out 150, and the upper pillar plate 170 is shorter in length than the lower pillar plate 270 and the upper pillar plate ( 170 is coupled to the inner column (IB) between the lower column plate 270, the upper end of the lower column reinforcement 210 is exposed through the lower column plate 270, the box out 150 In the upper column reinforcing bar 110 and the lower column reinforcing bar 210 provides a strong joint coupling structure between the upper and lower PC columns, characterized in that possible.
