Construction method of large-dip-angle lower-beam-free bridge tower
The invention discloses a construction method of a large-dip-angle lower-beam-free bridge tower. The construction method comprises the steps that S1, a lower tower column is constructed; s2, middle tower column construction; s3, the construction amount of an upper tower column is determined; s4, upper cross beam construction is conducted, a bracket method is adopted for an upper cross beam of a main tower, a synchronous construction scheme is adopted for tower columns on the two sides, a bracket system is installed on a tower body, the cross beam bracket system comprises an embedded part, a corbel profile steel bracket, a bearing beam, square timber and a bottom die, a steel plate is connected to the tower wall through bolts through the embedded part, corbel profile steel is welded to the embedded steel plate, and the bottom die is welded to the bracket profile steel bracket; the cross beam adopts a layered pouring mode. According to the construction method, construction of the large-dip-angle lower-beam-free bridge tower is effectively achieved, the specific and reasonable tower column construction method is provided aiming at the characteristics that a cable bent tower is of an inclined space structure and is large in inclination angle, active cross arms for tower column construction are large in stress, high-altitude installation difficulty is large and the like, the procedures are effectively simplified, all the procedures are matched with one another, and the construction efficiency is improved. The construction efficiency and quality are effectively improved, reference is provided for similar projects, and the method has extremely high popularization value.
本发明公开了一种大倾角无下横梁桥塔的施工方法，包括：S1：下塔柱施工；S2：中塔柱施工；S3：上塔柱施工量；S4：上横梁施工，主塔上横梁采用托架法与两侧塔柱采用同步施工方案，在塔身上安装托架体系，横梁托架体系包括预埋件、牛腿型钢托架、承重梁、方木及底模，预埋件将钢板通过螺栓连接在塔壁上，牛腿型钢与预埋钢板焊接，横梁采用分层浇筑方式。本发明有效的解决了大倾角无下横梁桥塔的施工，针对索塔为倾斜空间结构，索塔倾斜角度大，塔柱施工主动横撑受力大，高空安装难度大等特点，给出了具体且合理的塔柱施工方法，有效简化了工序、使各工序之间相互配合，有效提高了施工的效率和质量，为类似工程提供借鉴，具有极高的推广价值。
