Construction method of large-cantilever prestressed concrete bent cap
The invention provides a construction method of a large-cantilever prestressed concrete bent cap, and belongs to the field of construction of bridge structures in buildings with special purposes. The construction method comprises the following steps of: S1, constructing a support column foundation; S2, mounting a bracket steel pipe column; S3, manufacturing and mounting a beam falling sand box; S4, mounting a cross beam; S5, splicing and installing a bailey beam; S6, installing bottom formworks; S7, pre-pressing a bracket; S8, installing steel bars and embedded parts and constructing reserved holes; S9, mounting side formworks; S10, pouring bent cap concrete ; S11, dismantling the side formworks, and conducting concrete curing; S12, conducting bent cap pre-stress construction; and S13, dismantling the bracket and the bottom formworks. The bent cap construction method is simple and rapid, can greatly improve the construction efficiency, accelerates the construction progress, facilitates the control over the construction quality and the construction safety, reduces construction cost and is high in applicability.
本发明提供一种大悬臂预应力混凝土盖梁的施工方法，属于专门用途的建筑物中桥梁结构施工领域，包括如下步骤：步骤S1，支撑柱基础施工；步骤S2，支架钢管柱安装；步骤S3，落梁砂箱的制作和安装；步骤S4，横梁安装；步骤S5，贝雷梁的拼装和安装；步骤S6，底模安装；步骤S7，支架预压；步骤S8，钢筋安装、预埋件和预留孔洞施工；步骤S9，侧模安装；步骤S10，盖梁混凝土浇筑；步骤S11，侧模拆除及混凝土养护；步骤S12，盖梁预应力施工；步骤S13，支架及底模拆除。本发明的盖梁施工方法简单快捷，可以大幅度提高施工效率，加快施工进度，利于施工质量及施工安全的控制，且降低了施工成本，适用性强。
