Embodiment Construction
[0023] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0024] like Figures 1 to 4 As shown, the scheme of the present invention proposes a steel cable anchoring system for a lattice-type steel truss tower cable-stayed bridge, including steel anchor beams 1 welded on the lattice-type steel tower columns at both ends and connected on both sides of the steel anchor beam 1 The steel anchor box 2, the steel anchor beam 1 includes a beam body closed and welded by the bottom plate 11, the top plate 12 and the side plate 13, and a diaphragm 14 is arranged inside; and vertical stiffeners 16. The steel anchor box 2 includes the outer part of...

The invention belongs to the technical field of municipal bridge engineering, and particularly relates to a lattice steel truss tower cable-stayed bridge steel stay cable anchoring system which comprises a steel anchor beam welded on a lattice steel tower column and steel anchor boxes connected at two ends of the steel anchor beam, the steel anchor beam is formed by welding a bottom plate, a top plate and side plates in a closed manner, and a transverse partition is arranged inside the steel anchor beam; each steel anchor box comprises a tower column outside portion and a tower column inside portion, each of the tower column outside portion and the tower column inside portion is formed by welding side plates and top-bottom sealing plates, and each tower column outside portion and the corresponding tower column inside portion are welded with the lattice steel tower column; each steel anchor box further comprises a steel cable protective sleeve which is welded with top-bottom plates andside plates of the corresponding steel anchor box through vertical reinforcing ribs; a steel anchor box subplate is arranged at the top of the tower column outside portion of each steel anchor box, and the lower side of each steel anchor box subplate is provided with vertical reinforcing ribs on two sides of the tower column inside portion of the corresponding steel anchor box. The problem that asteel stay cable at one end of the steel tower column of a steel tower cable-stayed bridge is difficult in anchoring is solved, force transmission path of the steel stay cable is specified, and cableforce is uniformly transmitted onto the steel tower column.
Description
technical field [0001] The invention belongs to the technical field of municipal bridge engineering design, in particular to a steel cable anchoring system for a lattice-type steel truss tower cable-stayed bridge. Background technique [0002] A cable-stayed bridge is a kind of bridge in which the main beam is directly pulled on the bridge tower with many cables, and it is a structural system composed of a compression tower, a tension cable and a bending beam body; The anchoring form between the tower column and the steel cable of the steel truss tower cable-stayed bridge has become a difficult point in the design of this type of cable-stayed bridge. [0003] The cable of the cable-stayed bridge is the key component connecting the main tower and the main bridge. The cable bears a lot of force, and the stress at the connection part between the cable and the steel tower column is relatively concentrated. Simple and effective transmission of tension, thus meeting the safety re...
