Segment prefabricated and assembled bridge pier stud and construction method thereof
The invention discloses a segment prefabricated and assembled bridge pier stand. The pier stand comprises a bearing platform, a pier stud body and a bent cap connecting segment which are arranged frombottom to top, and the pier stud body is prefabricated and assembled in a segmented mode and comprises a plurality of same pier stud sections; the lower portion of each pier stud section is a protruding prismoid, the upper portion of each pier stud section is a prismoid groove, the protruding prismoid and the prismoid groove are nested in a spaced mode, vertical steel bars are pre-buried in the pier stud sections and protrude upwards, and grouting sleeves are arranged at the lower ends of the vertical steel bars and connected with the vertical steel bars; the upper portion of the bearing platform is an annular protrusion, vertical steel bars are embedded in the annular protrusion and protrude upwards, and a prismoid groove is formed in the annular protrusion on the upper portion of the bearing platform; the lower portion of the bent cap connecting section is a protruding prismoid, vertical reinforcing steel bars are embedded in the lower portion of the bent cap connecting section, grouting sleeves are arranged at the bottoms of the vertical reinforcing steel bars and connected with the vertical reinforcing steel bars, and the protruding prismoid on the lower portion of the bent cap connecting section and prismoid groove in the upper portion of each pier stud section are nested in a clearance mode. The bridge pier stud is good in stress and stable in structure. The invention further discloses a construction method of the bridge pier stud. Construction is convenient and efficient.
本发明公开了一种节段预制拼装的桥梁墩柱，包括由下而上设置的承台、墩柱本体和盖梁连接节段，所述墩柱本体为分段式预制拼装，其包括若干相同的墩柱节段；墩柱节段下部为凸出的棱台，上部为棱台凹槽，且两者形状大小互为间隙嵌套，墩柱节段上预埋有竖向钢筋并向上冒出，竖向钢筋下端均有注浆套管与之相连；承台上部为环形凸起，且预埋有竖向钢筋向上冒出，承台上部环形凸起内部为棱台凹槽；盖梁连接节段下部为凸出的棱台，且预埋有竖向钢筋，在竖向钢筋底部有注浆套管与之相连，盖梁连接节段下部凸出的棱台与墩柱节段上部棱台凹槽为间隙嵌套。该桥梁墩柱的受力更好，结构更稳定。本发明还公开了上述桥梁墩柱的施工方法，施工便利高效。
