Prestress large cantilever inverted T-shaped variable cross-section bent cap and construction method
The invention relates to a prestressed large-cantilever inverted-T-shaped variable-cross-section bent cap and a construction method, adopts a radial cow foot bracket or a ring-lock scaffold as a support system, and provides a ring-lock scaffold as the support system, so that smooth construction of the large-cantilever inverted-T-shaped variable-cross-section bent cap is effectively guaranteed. A radial corbel bracket is provided to serve as a formwork supporting structure, the upper portion of a radial telescopic corbel inclined strut can be selectively connected with different radial corbel inclined strut connecting points according to the length of a bent cap cantilever, and the applicability is effectively expanded; the telescopic operation platform for hanging the prefabricated tensioning hoop cover beam is developed, the vertical position of the telescopic operation platform for hanging the prefabricated tensioning hoop cover beam is controlled through the telescopic device control end, tensioning and anchor sealing of a tensioning steel beam are carried out at notches in the two sides of the large cantilever cover beam, and the prestress tensioning construction efficiency is effectively improved.
本发明涉及一种预应力大悬臂倒T形变截面盖梁及施工方法，采用放射状牛脚托架或盘扣式脚手架作为支架体系，提出了一种盘扣式脚手架作为支架体系，有效保证了大悬臂倒T形变截面盖梁的顺利施工；提出了一种放射状牛腿托架作为支模结构，放射状可伸缩牛腿斜撑上部可根据盖梁悬臂的长度选择与不同的放射状牛腿斜撑连接点相连，有效拓展了其适用性；研制了一种预制张拉抱箍盖梁吊挂可伸缩式操作平台，通过可伸缩装置控制端控制预制张拉抱箍盖梁吊挂可伸缩式操作平台的上下位置，在大悬臂盖梁两侧槽口进行张拉钢束的张拉并封锚，有效提高了预应力张拉施工效率。
