Assembly type buttress-free support mounting method
The invention relates to the technical field of bridge construction, in particular to an assembly type buttress-free support installation method which comprises the following steps that S1, the specification and the number of all components are calculated according to the span of a bridge, and prefabrication is completed in a factory; s2, horizontally splicing a single-piece bracket, erecting the bracket, and then mounting a middle assembly to complete the assembly of the assembled longitudinal beam; s3, fixing pieces and main cross beams are installed at bridge pier columns; s4, integrally hoisting the assembly type longitudinal beam; s5, installing a transverse distribution beam assembly; and S6, longitudinal distribution beam assemblies are installed. By means of the method, connection between the assemblies can be simpler and more convenient, the assembling difficulty of the assembly type longitudinal beam can be effectively reduced, and the installation precision is improved; the fixing pieces are installed on the bridge pier columns, installation of stand columns is omitted, the construction period is shortened, and cost is reduced. By means of integral hoisting, the overhead working time of workers can be shortened, the safety risk can be reduced, hoisting and assembling of the next assembly type longitudinal beam can be carried out at the same time, the construction period can be greatly shortened, and cost is reduced.
本发明涉及桥梁施工技术领域，特别涉及一种装配式无支墩支架安装方法，包括如下步骤：S1.根据桥梁跨径计算各构件规格及数量，并在工厂完成预制；S2.卧拼单片支架，将支架直立后安装中间组件，完成装配式纵梁的组装；S3.在桥梁墩柱处安装固定件及主横梁；S4.整体吊装装配式纵梁；S5.安装横向分配梁组件；S6.安装纵向分配梁组件。使用本发明所述方法，可以使各组件之间的连接更为简单、方便，可有效降低装配式纵梁的拼装难度、提高安装精度；在桥梁墩柱上安装固定件，取消了立柱的安装，有利于缩短工期、降低成本；整体吊装可减少工人高空作业时间，有利于降低安全风险，并且能同时进行吊装和下一装配式纵梁的组装，可大幅缩短工期、降低成本。
