Cable-stayed bridge concrete door type cable bent tower stiffening structure
The invention belongs to the technical field of bridge engineering, and particularly relates to a cable-stayed bridge concrete door type cable bent tower stiffening structure which comprises two symmetrically-arranged tower columns, a bearing platform fixedly connected to the bottom ends of the tower columns, a pier column fixedly connected to the bottom end of the bearing platform, a fixing part fixedly connected to the bottom end of the pier column and fixed to the ground, and a bearing part fixedly connected between the two tower columns. A bridge is erected at the top end of the bearing part, horizontally-arranged upper cross beams are fixedly connected between the top ends of the two tower columns, and stiffening structures are arranged between the two ends of the tower columns and the two upper cross beams. The cable-stayed bridge overcomes the defects that in a traditional cable-stayed bridge, vertical prestress is arranged in a tower column to improve stress, consequently, the internal structure of the tower column is complex, and the effectiveness of the prestress is difficult to control, and the stiffening structures are arranged between the two ends of the upper cross beam and the two tower columns, so that the connecting strength of the connecting positions of the top ends of the tower columns and the upper cross beam is effectively improved; the transverse bending moment of the top end of the tower column is reduced, the durability of the tower column is improved, and meanwhile creeping formwork construction of the tower column of the cable bent tower is not affected.
本发明属桥梁工程技术领域，尤其涉及一种斜拉桥砼门式索塔加劲构造，包括：两个对称设置的塔柱，塔柱的底端固接有承台，承台的底端固接有墩柱，墩柱的底端固接有固定部，固定部与地面固定，两塔柱之间固接有承载部，承载部的顶端搭设有桥梁，两塔柱的顶端之间固接有水平设置的上横梁，塔柱的两端与两个上横梁之间均设置有加劲结构。本发明克服了传统的斜拉桥在塔柱内部设置竖向预应力改善受力，造成塔柱内部构造复杂且预应力有效性难以控制的缺点，通过在上横梁的两端与两塔柱之间设置加劲结构，有效提高塔柱顶端与上横梁连接处的连接强度，降低了塔柱顶端的横向弯矩，提高了塔柱的耐久性能，同时不会影响索塔塔柱爬模施工。
