Automatic creeping formwork mechanism for cable bent tower and construction method
The invention belongs to the technical field of bridge construction, and particularly relates to a cable bent tower automatic creeping formwork mechanism and a construction method.The cable bent tower automatic creeping formwork mechanism comprises a pile group inserted into concrete and a creeping formwork intelligent informatization system, the upper surface of the pile group is fixedly connected with a rectangular bearing platform, and the upper surface of the rectangular bearing platform is fixedly connected with a hollow segment cable bent tower; a climbing mechanism is arranged on one side of the segment cable bent tower, holding mechanisms are arranged on the outer surface of the segment cable bent tower, and a lifting mechanism is arranged between the upper holding mechanism and the lower holding mechanism. According to the automatic formwork climbing mechanism for the cable bent tower and the construction method, the jacking air cylinders act through loosening of the holding mechanism at the upper end, the jacking air cylinders at the two ends synchronously push the holding mechanism at the upper end upwards, after the outer surface of the built cable bent tower ascends by a certain distance, the holding mechanisms continue to hold tightly, and at the moment, the jacking air cylinders are loosened through the holding mechanism at the lower end; and the stretching air cylinder upwards stretches the lower end holding mechanism, so that the holding mechanism for releasing the mold gradually climbs to realize automatic holding and releasing of the mold.
本发明属于桥梁施工技术领域，尤其是一种索塔自动爬模机构及施工方法，包括插入混凝土中的群桩和爬模智能信息化系统，群桩的上表面固定连接有矩形承台，矩形承台的上表面固定连接有空心的节段索塔，节段索塔的一侧设置有爬升机构，节段索塔的外表面设置有抱紧机构，上下两个抱紧机构之间设置有提升机构。该索塔自动爬模机构及施工方法，通过上端抱紧机构的松弛而使顶推气缸进行动作，两端的顶推气缸同步向上推动上端的抱紧机构，在搭建完成的索塔外表面上升一段距离之后抱紧机构继续抱紧，此时再通过下端的抱紧机构松弛，使拉伸气缸向上拉伸下端抱紧机构，从而可使放模的抱紧机构逐步爬升实现自动抱紧放模。
