Cable-stayed bridge main tower cross beam construction bracket and construction method thereof
The invention discloses a cable-stayed bridge main tower cross beam construction bracket and a construction method thereof.The cable-stayed bridge main tower cross beam construction bracket comprises an assembly type bracket and a triangular steel bracket, the triangular steel bracket is arranged on the assembly type bracket and used for supporting an upper cross beam and bearing loads, the triangular steel bracket comprises a vertical rod, and the vertical rod is connected with a first inclined strut; according to the cable-stayed bridge main tower beam construction bracket and the construction method thereof, the triangular steel bracket, the upper beam and the main tower column form a triangle in a surrounding mode, the structure is stable, the construction period of the upper beam is shortened, efficiency is improved, cost is low, safety risks of high-altitude operation are reduced, mounting and dismounting are convenient, and the problem that in an existing construction mode, the weight of the beam is too large; the problems that a common bracket cannot be realized, or the section and a rod piece are too thick and heavy, the shearing force of the joint of the common bracket and a main tower is too large, anchoring is difficult, mounting and dismounting are difficult, recycling cannot be achieved, and waste is caused are solved.
本发明公开了一种斜拉桥主塔横梁施工托架及其施工方法，包括装配式牛腿，以及三角型钢托架，该三角型钢托架设置在装配式牛腿上，所述三角型钢托架用于支撑上横梁，承担荷载，所述三角型钢托架包括竖杆，所述竖杆连接有第一斜撑；该斜拉桥主塔横梁施工托架及其施工方法，三角型钢托架与上横梁和主塔塔柱围绕成三角形，结构稳固，使上横梁的施工工期缩短，效率提高，成本便宜，降低了高空作业的安全风险，安装拆卸便利，解决了现有的施工方式由于横梁重量过大，普通的托架无法实现，或者截面和杆件过于粗大、笨重，与主塔连接处剪力过大、锚固困难，安装和拆卸困难，又无法再次利用，造成浪费的问题。
