Cross-valley non-standard span cast-in-place beam support and construction method
The invention belongs to the field of highway bridge construction, and particularly relates to a cross-valley non-standard span cast-in-place beam support and a construction method. The cross-valley non-standard span cast-in-place beam support comprises a bridge pier, pre-buried holes are formed in the bridge pier, steel bars are installed in the pre-buried holes, main cross beams are arranged on the two sides of the bridge pier at the upper ends of the steel bars respectively, the two main cross beams are fixedly connected to the bridge pier through opposite-pull threaded steel bars and installation nuts, and a plurality of bailey beams are arranged at the top ends of the main cross beams and fixed through flower stands. A plurality of I-shaped steel distribution beams are uniformly arranged at the upper end of the bailey beam, the I-shaped steel distribution beams are fixedly connected with the bailey beam through U-shaped buckles, plate buckle type scaffolds are arranged on the I-shaped steel distribution beams, square timbers are mounted at the upper ends of the plate buckle type scaffolds, and bamboo plywood is laid on the square timbers. The pier body of the bridge pier is used as an integral bearing structure of the support, and the high-strength steel bars and the ultra-large H-shaped steel are used as main stress components, so that the foundation treatment construction difficulty of the cast-in-place beam support and the material consumption of the support are effectively reduced, and the engineering construction cost is saved.
本发明属于高速路桥梁施工领域，具体涉及到一种跨沟谷非标跨度现浇梁支架及施工方法。包括桥墩，桥墩上设置有预埋孔，预埋孔内安装有钢棒，钢棒上端桥墩的两侧分别设置有主横梁，两主横梁通过对拉螺纹钢筋以及安装螺帽固定连接于桥墩上，主横梁的顶端设置有若干贝雷梁，贝雷梁之间通过花架固定，贝雷梁上端均匀设置有若干工字钢分配梁，工字钢分配梁通过U型扣与贝雷梁固定连接，工字钢分配梁上设置有盘扣式脚手架，盘扣式脚手架上端安装方木，方木上铺设竹胶板。本申请将桥墩墩身作为支架整体承载结构，并利用高强度的钢棒、超大型H型钢作为主要受力构件，有效降低了现浇梁支架地基处理施工难度和支架材料消耗量，节省了工程施工成本。
