Asynchronous construction method for bridge cable bent tower and upper cross beam of bridge cable bent tower
The invention relates to an asynchronous construction method for a bridge cable bent tower and an upper cross beam thereof, which comprises the following steps: S1, when a tower column of the cable bent tower is constructed to the upper cross beam, pre-burying a plurality of connecting units on the inner side surface of the tower column for connecting a plurality of triangular support brackets below the upper cross beam; s2, a plurality of connecting sleeves and reserved pipeline holes are arranged in the positions, corresponding to the upper cross beams, of the inner side face of the tower column; s3, after tower column construction is completed, the triangular supporting bracket comprises an upper bracket support and a lower bracket support, and each bracket support is correspondingly connected with one connecting unit; s4, the main reinforcements in the upper cross beam are connected with the connecting sleeves, and then the main reinforcements and the remaining reinforcements of the upper cross beam are bound; connecting the prestressed pipeline in the upper cross beam with the reserved pipeline hole; s5, first-batch concrete pouring and curing of the upper cross beam are carried out, tensioning is carried out after curing is qualified, second-batch concrete pouring is carried out after strength is qualified, and tensioning and grouting are carried out after curing is qualified; and finally, the triangular supporting bracket is dismantled.
本发明涉及一种桥梁索塔与其上横梁的异步施工方法，包括：S1：在索塔的塔柱施工至上横梁处时，在塔柱的内侧面上预埋若干个连接单元，用于连接上横梁下方的若干个三角支撑托架；S2：在塔柱的内侧面且对应上横梁的位置设置若干个连接套筒和预留管道孔；S3：待塔柱施工完成后，三角支撑托架包括上下两个牛腿支架，每个牛腿支架对应连接一个连接单元；S4：将上横梁内的主筋连接连接套筒，再进行上横梁的主筋和剩余钢筋的绑扎；将上横梁内的预应力管道连接预留管道孔；S5：进行上横梁的第一批次混凝土浇筑，养护合格后，进行张拉，强度合格后，进行第二批次混凝土浇筑，养护合格后，进行张拉、压浆；最后拆除三角支撑托架。
