Cable-stayed bridge cast-in-place beam support construction method for meeting flood control requirement
The invention discloses a cable-stayed bridge cast-in-place beam support construction method for meeting the flood control requirement. A main bridge strip at a cantilever is 5.45 m in length and large in width, in order to facilitate supporting, five 145a type distribution beams are arranged below the cantilever, the distance between every two distribution beams is 1.2 m, in order to prevent the distribution beams from moving under the action of web diagonal rods, steel plate supports are used for fixing, a supporting support is welded to a bearing beam, a main body support 2145a bearing beam extends to a cantilever to serve as a supporting structure at the cantilever, and two rows of full-length 132b I-shaped steel are arranged below the cantilever in the bridge direction to serve as a cantilever structure supporting structure. In order to prevent cast-in-place beam side formworks from deforming during concrete pouring, two supporting inclined rods are arranged on the side formworks on each section, low-alloy high-strength steel is adopted, the bearing capacity is high, the safety coefficient is considered, the using amount of materials is small, the installation is rapid, easy and convenient, and the efficiency is high; and the box beam is provided with a fulcrum cross beam, the width of the end fulcrum cross beam is 1.5 m, hot galvanizing anti-corrosion treatment is conducted, the firmness and durability are achieved, the turnover frequency is high, and the cost is saved.
本发明公开了一种用于满足度汛的斜拉桥现浇梁支架施工方法，悬臂处主桥条比长度为5.45m，宽度较大，为了便于支撑，在挑臂下方布置5道145a型分配梁，间距为1.2m，为了避免分配梁在腹板斜杆的作用下移动，用钢板支架进行固定，支撑支架焊接在承重梁上，臂处利用主体支架2145a承重梁延伸至悬臂处作为支撑结构，在悬臂下方顺桥向设置两排通长132b工字钢作为悬臂结构支撑结构，为了防止混凝土浇筑时现浇梁侧模板发生变形，在每个截面均在侧模板上设置两根支撑斜杆，采用低合金高强度钢，承载能力高，考虑安全系数，材料用量少，安装快捷、简便，效率高；箱粱设有支点横梁,端支点横粱宽度1.5m，热镀锌防腐处理，坚固耐用，周转次数高，节约成本。
