Continuous beam side span straight-line section hanging support device without closure section and construction method of continuous beam side span straight-line section hanging support device
The invention relates to a continuous beam side-span closure-section-free linear section hanging support device and a construction method, and belongs to the technical field of bridge construction, the continuous beam side-span closure-section-free linear section hanging support device comprises a supporting cushion block located on the pier top of a side-span pier body, and a bearing beam extending in the transverse bridge direction is arranged at the top of the supporting cushion block; the cork base cross beam is hung at the bottom of the formed continuous beam body through a steel hanging belt in the transverse bridge direction; one end of the bottom support longitudinal beam is fixed to the top of the bottom support cross beam, and the other end of the bottom support longitudinal beam is slidably connected to the top of the bearing beam; the formwork system comprises a bottom formwork and a side formwork which are located on the top of the collet longitudinal beam. According to the linear section hanging support device and the construction method, in the linear section pouring process, the bottom support cross beams, the bottom support longitudinal beams and the formwork system drive the linear section to move along with the formed continuous beam body, and the situation that the new and old concrete combination face of the linear section and the formed continuous beam body is pulled to crack due to stretching and creep of the formed continuous beam body is prevented.
本申请涉及一种连续梁边跨无合龙段的直线段吊架装置及施工方法，属于桥梁施工技术领域，包括：支撑垫块，其位于边跨墩身的墩顶上，在支撑垫块的顶部设有沿横桥向延伸的垫梁；底托横梁，其沿横桥向通过钢吊带吊挂于已成连续梁体的底部；底托纵梁，其一端固定在底托横梁的顶部，底托纵梁的另一端滑动连接在垫梁的顶部；模板系统，其包括位于底托纵梁顶部的底模和侧模。本申请的直线段吊架装置及施工方法在直线段浇筑过程中，底托横梁、底托纵梁和模板系统带着直线段随着已成连续梁体一起运动，防止因已成连续梁体伸缩、徐变导致直线段与已成连续梁体新旧混凝土结合面受拉开裂。
