Overpass prefabricated bent cap mounting method
The invention discloses a method for installing a prefabricated bent cap of an overpass. The method comprises the following steps that S1, observation marks are pasted, wherein the observation marks are pasted to the end of the prefabricated bent cap, the center point of the side face of the prefabricated bent cap and the center point of a stand column; S2, pre-assembling is carried out; wherein the prefabricated bent cap is hoisted to the upper end of the stand column, then the position of the prefabricated bent cap on the stand column is adjusted by observing the observation marks, and the position of the prefabricated bent cap is marked after the prefabricated bent cap is adjusted to the required position; and S3, formal splicing is conducted, specifically, the marked prefabricated bentcap is hoisted, then stand column top seat slurrying is conducted, the bent cap is hoisted to the top of the stand column after the slurrying, the correction is conducted according to the observationmarks and marks, and then the formal splicing of the prefabricated bent cap and the stand column is completed. According to the invention, multiple observation marks are set at the prefabricated bentcap and the stand column, meanwhile, the prefabricated bent cap is pre-spliced and formally spliced, and the perpendicularity, planeness and elevation of the bent cap are pre-positioned and re-checked through the observation marks in the splicing process, so that the splicing precision is greatly improved.
本发明公开了一种高架桥预制盖梁安装方法，包括以下步骤：S1、粘贴观测标：在预制盖梁的端头、预制盖梁侧面中心点、立柱中心点粘贴观测标；S2、预拼装；将预制盖梁吊装到立柱上端，然后通过观察观测标调整预制盖梁在立柱上的位置，调整至所需位置后对预制盖梁位置进行标记；S3、正式拼装：将标记后的预制盖梁吊起，然后进行立柱顶座浆，座浆后将盖梁吊装至立柱顶，并根据观测标、标记进行校正，进而完成预制盖梁与立柱的正式拼接，本发明通过在预制盖梁以及立柱上设置多处观察标志，同时对预制盖梁进行预拼接、正式拼接，而且在拼接的过程中通过观察标志对盖梁的垂直度、平面度、标高进行预定位以及复核，进而极大的提高了拼装精度。
