Reverse matching prefabrication method for full-suspension segmental beam
The invention discloses a reverse matching prefabrication method for a full-suspension segmental beam. The reverse matching prefabrication method comprises the following steps that S1, the segmental beam is prefabricated on a standard segmental beam pedestal; s2, prefabricating a first section of side section beam from the middle section as the center to the left side and the right side gradually and outwards, and connecting the first section of side section beam with the middle section in a matched manner; s3, two second-section side section beams continue to be prefabricated towards the left side and the right side at the same time; and S4, the step S3 is repeated until prefabrication, matching and connection of all the side segmental beams are completed. According to the prefabrication construction method, the middle segmental beam is firstly prefabricated, then the middle segmental beam is prefabricated towards the two sides, repeated hoisting of the segmental beams can be reduced, and the safety risk is reduced; the number of bottom die trolleys is reduced, and the construction cost is reduced; the matching rate of the segmental beams is increased, and after the middle segmental beam is prefabricated, the two sides of the middle segmental beam can be prefabricated at the same time.
本发明公开了一种全悬挂节段梁逆向匹配预制方法，包括以下步骤：步骤S1、在标准节段梁台座上预制节段梁；步骤S2、以所述中间节段为中心分别同时向左侧、右侧逐步向外进行第一节侧边节段梁的预制，将二者进行匹配连接；步骤S3、再继续同时向左侧、右侧预制两个第二节侧边节段梁；步骤S4、重复上述步骤S3，直至完成所有的侧边节段梁的预制、匹配和连接。本发明的预制施工方法先预制中间的节段梁，再由中间的节段梁向两侧预制，可以减少节段梁的反复吊装，降低安全风险；减少了底模台车的数量，降低施工成本；增加了节段梁匹配速率，中间节段梁预制完成后，可以两侧同时预制。
