Rigid frame bridge side span cast-in-place section and closure section formwork structure and construction method thereof
The invention discloses a rigid frame bridge side span cast-in-place section and closure section formwork structure and a construction method thereof, and relates to the technical field of rigid frame bridge construction. Comprising a steel plate bracket which is pre-embedded in the side part of a main bridge cover beam; the pier outer bottom die comprises a front lower cross beam, a rear lower cross beam and a bottom basket, the front lower cross beam is arranged at the top of the steel plate bracket, the rear lower cross beam is anchored to the suspended pouring section, and the bottom basket is arranged between the front lower cross beam and the rear lower cross beam; the leveling support is arranged at the top of the approach bridge cover beam; the pier outer wing plate comprises a hanging basket outer sliding beam, and the hanging basket outer sliding beam is arranged on the leveling support; the pier top bottom die is made of leveling wet sand, and the leveling wet sand is laid on the top of the main bridge cover beam. According to the method, bottom formwork erecting operation of the side span cast-in-place section and the side span closure section is completed at a time, the method can be suitable for rigid frame bridge side span cast-in-place section and closure section construction of abutments of all heights, and the method has the advantages of being free of brackets, high in construction speed, good in construction safety, low in construction cost and the like.
本发明公开了一种刚构桥边跨现浇段与合拢段支模结构及其施工方法，涉及刚构桥施工技术领域。包括：钢板牛腿，钢板牛腿预埋在主桥盖梁的侧部；墩外底模，墩外底模包括前下横梁、后下横梁和底篮，前下横梁设置于钢板牛腿的顶部，后下横梁锚固于悬浇段，底篮设置于前下横梁和后下横梁之间；调平支撑，调平支撑设置于引桥盖梁的顶部；墩外翼板，墩外翼板包括挂篮外滑梁，挂篮外滑梁设置于调平支撑上；墩顶底模，墩顶底模采用调平湿砂，调平湿砂铺设于所述主桥盖梁的顶部。本发明一次完成边跨现浇段及边跨合拢段底模支模作业，可适用于所有高度墩台的刚构桥边跨现浇段及合拢段施工，具有免托架、施工速度快、施工安全性好、施工成本低等优点。
