Sectional prefabrication and installation construction method for Y-shaped pier capping beam
The invention discloses a Y-shaped pier bent cap segmented prefabrication and installation construction method which comprises the following steps: S1, according to design requirements, a bent cap shell is prefabricated in a segmented mode, and the bent cap shell comprises a middle prefabricated section and cantilever prefabricated sections located at the two ends of the middle prefabricated section; the cover beam shell is of a shell-shaped structure with the top open. S2, a support platform is installed on the Y-shaped pier column, a middle prefabricated section and two cantilever prefabricated sections are hoisted to the support platform, and gaps are formed between the middle prefabricated section and the two cantilever prefabricated sections; s3, a cast-in-place formwork is installed in the gap between the middle prefabricated section and the two cantilever prefabricated sections, concrete is poured into the cast-in-place formwork, so that the middle prefabricated section and the two cantilever prefabricated sections are connected into a whole, and an open groove type structure is formed; and S4, concrete is poured into the open groove type structure, and capping beam construction is completed. According to the method, rapid construction of the bent cap is achieved, the problem of limitation of transportation and hoisting of the large-size bent cap is solved, and the method has a large development prospect under the urban limited operation condition.
本发明公开了一种Y形墩盖梁分段预制安装施工方法，包括以下步骤：S1、根据设计要求，将盖梁外壳分段预制，包括中间预制段和位于所述中间预制段两端的悬挑预制段；所述盖梁外壳为顶部敞开的壳形结构；S2、在Y形墩柱上安装支架平台，吊装中间预制段和两个悬挑预制段至支架平台上，所述中间预制段和两个悬挑预制段之间具有间隙；S3、在中间预制段和两个悬挑预制段的间隙处安装现浇模板，向现浇模板内浇筑混凝土使中间预制段和两个悬挑预制段连接成整体，以形成敞口槽式结构；S4、向敞口槽式结构内浇筑混凝土，完成盖梁施工。本发明既实现了盖梁快速施工，又解决了大体积盖梁运输及吊装的限制，在城市受限作业条件下具有较大的发展前景。
