Special construction method for upper cross beam of main bridge tower column of bridge
The invention discloses a special construction method for an upper cross beam of a main bridge tower column of a bridge, and relates to the technical field of main bridge tower columns of the bridge, an upper cross beam support system is arranged, the support system is composed of a reinforced embedded box, a bracket, a bearing beam, an XT300 truss, a distribution beam and square wood bamboo plywood, and the specific arrangement form of a support from bottom to top is that the reinforced embedded box is embedded in the bracket; reinforcing type embedded boxes are embedded in the upper end and the lower end of the tower column in the longitudinal bridge direction respectively, six rows of brackets are arranged on the support in the transverse bridge direction to serve as supports, transverse parallel connection and inclined struts between the brackets are connected through [14] and [10] combined channel steel respectively, the overall stability of the support is guaranteed, the stability of the bridge is enhanced, and cross beams can prevent the bridge floor from deviating, inclining, collapsing and the like. The overall stability of the bridge is enhanced; loads are distributed, through the effect of the transverse beam structure, the loads on the bridge can be evenly distributed to the pier columns and the foundation of the lower structure through the transverse beams, the stress concentration ratio of bridge components is reduced, and reasonable layout and evenly-distributed loads of the bridge are achieved.
本发明公开了一种大桥主桥塔柱上横梁专用施工方法，涉及大桥主桥塔柱技术领域，上横梁支架体系布置，支架体系由加强型预埋盒、托架、承重梁、XT300桁架、分配梁、方木竹胶板组成，支架由下到上具体布置形式为，纵桥向分别在塔柱两端上下预埋加强型预埋盒，支架横桥向设置6排托架作为支撑，托架之间横向平联及斜撑分别采用[14与[10组合型槽钢连接，保证支架的整体稳定性，增强桥梁稳定性，横梁能够防止桥面产生偏移、倾斜、塌陷等现象，增强桥梁的整体稳定性；分布荷载，通过横向梁构造的作用，横梁能够将桥梁上的荷载均匀分布到下部结构的墩柱和地基上，降低桥梁部件的应力集中度，实现桥梁的合理布局和均匀分布的荷载。
