High-pier large-cantilever bent cap support and construction method
The invention discloses a high-pier large-cantilever bent cap support and a construction method, and relates to the technical field of high-pier large-cantilever bent cap construction, the support comprises landing leg assemblies with the same number as pier columns in the transverse bridge direction, and each landing leg assembly comprises two first brackets arranged on the two sides of the corresponding pier column in the longitudinal bridge direction; the two Bailey beams are connected to the tops of the first brackets on the two sides of the pier column correspondingly; the plurality of first distribution beams are arranged at the tops of the two groups of bailey beams and are used for supporting a capping beam template; the supporting frame is used for being arranged on the side wall of the pier column on the outermost side so as to support the cantilever end, stretching out of the pier column, of the bailey beam. The method comprises the steps that a first bracket, a supporting frame, a bailey beam and a first distribution beam are sequentially installed, and installation of a bent cap support is completed; a bent cap formwork is laid, and concrete pouring is conducted; and dismantling the bent cap bracket according to the reverse installation sequence. According to the scheme, the bent cap support is a non-standard bent cap support, and the problems that in the prior art, a support is heavy in structure, poor in stability, low in construction efficiency and large in steel consumption are solved.
本发明公开了一种高墩大悬臂盖梁支架及施工方法，涉及高墩大悬臂盖梁施工技术领域，该支架包括：与横桥向墩柱数量相同的支腿组件，每一支腿组件包括沿纵桥向分别用于设置在对应所述墩柱两侧的两个第一牛腿；两组贝雷梁，分别连接在墩柱两侧第一牛腿的顶部；多个第一分配梁，设置在两组贝雷梁顶部，用于支撑盖梁模板；支撑架，用于设在最外侧墩柱的侧壁上，以支撑贝雷梁伸出墩柱的悬臂端。该方法包括：依次安装第一牛腿、支撑架、贝雷梁和第一分配梁，完成盖梁支架安装；铺设盖梁模板，进行混凝土浇筑；按照安装的逆顺序拆除盖梁支架。本方案的盖梁支架为非标准盖梁支架，解决了现有技术中支架结构笨重、稳定性差、施工效率低、钢用量大的问题。
