Continuous rigid frame bridge side span cast-in-place section construction method
The invention discloses a continuous rigid frame bridge side span cast-in-place section construction method. The construction method comprises the following steps of pouring pier columns, pre-buryingsteel longitudinal beams and pre-burying steel plates, prefabricating beams, connecting the prefabricated beams, connecting steel oblique beams, connecting diagonal bracings, laying I-shaped steel, erecting supports and formworks, and constructing the side span cast-in-place section. The approach bridge prefabricated beam is erected in advance after construction of the stand columns is completed,and balance weight is provided for side span cast-in-place straight line section construction. When a continuous rigid frame side span cast-in-place section is constructed, a bracket is not needed forcounter-pressure balance weight. During construction, only the single-side bracket needs to be pre-pressed, whether the bracket is qualified or not is checked, and side span cast-in-place section construction can be conducted after pre-pressing is completed.
本发明公开了一种连续刚构桥边跨现浇段施工方法，本发明按以下步骤施工：浇筑墩柱并预埋钢纵梁和预埋钢板→预制梁→连接预制梁→连接钢斜梁→连接剪刀撑→铺设工字钢→支设支架和模板→施工边跨现浇段。本发明在立柱施工完毕后提前架设引桥预制梁，为边跨现浇直线段施工进行配重。在施工连续刚构边跨现浇段时无需托架反压配重配重。在施工时只需对单侧托架进行预压，检验托架是否合格，预压完成后即可进行边跨现浇段施工。
