Installation method of arch foot structure
The invention discloses a mounting method of an arch springing structure. The mounting method comprises the following steps that 1, the arch springing structure is divided; step 2, arch foot concrete structure construction; step 3, support jig frame and operation platform installation: the support jig frames are installed, and the operation platforms are erected between the upper concrete foundation and the support jig frames and between the support jig frames; 4, arch foot structure installation, wherein lower chords are hoisted, and web members between the lower chords are hoisted; the diagonal web members between the lower chord members and the bottommost upper chord members are firstly installed on the lower chord members, the bottommost upper chord members are hoisted, the upper chord members are fixed to the arch foot supports and the diagonal web members at the corresponding positions, and then the web members between the bottommost upper chord members and between the bottommost upper chord members and the lower chord members are installed. The operation platform is arranged on the upper portion of the supporting jig frame in the most economical supporting mode, the supports are combined with the platform, high-altitude in-situ bulk loading is carried out on the arch springing, the installation cost and the installation difficulty are greatly reduced, and meanwhile the safety of constructors is guaranteed.
本发明公开了一种拱脚结构的安装方法，包括以下步骤：步骤1：划分拱脚结构；步骤2：拱脚混凝土结构施工：步骤3：支撑胎架、操作平台安装：安装支撑胎架，在上部混凝土基础与支撑胎架之间、支撑胎架与支撑胎架之间搭设操作平台；步骤4：拱脚结构安装：吊装下弦杆，吊装下弦杆之间的腹杆；下弦杆上先安装下弦杆与最底部上弦杆之间的斜腹杆，吊装最底部上弦杆，并将上弦杆分别与对应位置处的拱脚支座和斜腹杆固定，随后安装最下部上弦杆间以及最下部上弦杆与下弦杆之间的腹杆。本申请选取最经济的支撑形式在支撑胎架上部设置操作平台，支撑与平台相结合，对拱脚进行高空原位散装，安装成本以及安装难度大大降低，同时保证了施工人员的安全。
