Segmental beam matching prefabrication method
The invention relates to a segmental beam matching prefabrication method which comprises the steps that S1, two adjacent segmental beams are prefabricated on a prefabrication platform according to the design size, and a post-pouring area is reserved at the beam end of one segmental beam at the joint of the two segmental beams; s2, the two prefabricated segmental beams are matched on a matching pedestal, the post-pouring area is located between the two segmental beams, and according to the geometric relative relation between the two segmental beams, the spatial positions of the two segmental beams are adjusted through beam face feature measuring points till the deviation meets the requirement; s3, the two segmental beams are reinforced and locked, and a pouring formwork is arranged in the post-pouring area; and S4, concrete is poured in the post-pouring area to form a post-pouring belt. The matching and prefabricating sequence of existing segmental beams is enriched, more optimization options are provided for construction organizations, and the technical problem that the construction period is long when segmental beams are prefabricated through an existing construction method is solved.
本发明涉及一种节段梁匹配预制方法，包括步骤：S1.将相邻的两段节段梁分别在预制台按设计尺寸预制，在两段所述节段梁的接合部，其中一段所述节段梁梁端部分预留有后浇区；S2.在匹配台座上将预制好的两段节段梁进行匹配，所述后浇区位于两段节段梁之间，根据两段节段梁之间的几何相对关系，利用梁面特征测量点，调整两段梁的空间位置，直至偏差满足要求；S3.加固锁定好两段节段梁，在后浇区设置浇筑模板；S4.在后浇区浇筑混凝土形成后浇带。丰富了现有节段梁匹配预制的顺序，让施工组织有更多的优化选项，解决现有施工方法预制节段梁时施工工期长的技术问题。
