Inserting groove-connected steel-concrete combined rigid frame bridge and construction method thereof
The invention discloses an inserting groove-connected steel-concrete combined rigid frame bridge and a construction method thereof. The steel-concrete combined rigid frame bridge comprises a pluralityof prefabricated main beam sections, pier columns, prefabricated cross beam sections, longitudinal connecting sections and transverse connecting sections, and the adjacent sections are connected in the longitudinal direction of a bridge to form main beam structures; the adjacent main beam structures are connected through the transverse connecting sections to form a bridge span structure; a prefabricated pier top section is divided into a prefabricated pier top section a and a prefabricated pier top section b, the prefabricated pier top section a is arranged over the pier columns, and there isno pier column under the prefabricated pier column section b; and a groove hole is formed in the prefabricated pier top section a, an exposed steel bar is arranged above the pier columns and insertedinto the groove hole, and high-strength concrete grout is poured into the groove hole to achieve connection of a prefabricated cross beam and the pier columns. An inserting groove-connected steel-concrete combined rigid frame bridge component is convenient to manufacture, transport and construct, the structural advantages of a steel-concrete combined beam and the advantages of assembled construction can be brought into full play, industrial production, segmented transportation and assembled construction can be achieved, and the requirement for green development is met.
本发明公开了一种插槽连接的钢混组合刚构桥梁及其施工方法，该钢混组合刚构桥梁包括若干预制主梁节段、墩柱、预制横梁节段、纵向连接段以及横向连接段，相邻节段纵桥向连接形成主梁结构，相邻主梁结构通过横向连接段连接形成桥跨结构。预制墩顶节段分为预制墩顶节段a与预制墩顶节段b，预制墩顶节段a设置在墩柱正上方，预制墩柱节段b正下方无墩柱；预制墩顶节段a设有槽孔，墩柱上方设置外露钢筋插入槽孔，向槽孔内部灌入高强混凝土浆实现预制横梁与墩柱的连接。插槽连接的钢混组合刚构桥梁构件制作、运输、施工方便，有利于充分发挥钢混组合梁的结构优势和装配化建造的优势，可实现工业化生产、分段运输、装配化施工，符合绿色发展需求。
