Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0024] Such as figure 1 and figure 2 As shown, the present invention proposes a lattice type steel truss tower cable-stayed bridge, comprising a tower pier 1, a tower column 2 connected to the tower pier 1 and a tower top beam 3 connected to the top of the tower column 2, the tower There are two columns. The tower column 2 includes four box-shaped steel columns. The tower column 2 is provided with "T"-shaped ribs, and the tower column 2 is provided with a "one" shape (horizontal brace 4). And "X" type (diagonal bracing 5) supporting structure, both are in the form of st...

Abstract

The invention belongs to the technical field of bridge engineering design, and particularly relates to a lattice steel truss tower cable-stayed bridge which comprises two tower piers, a tower column connected on the tower piers and a tower top crossbeam connected at the top end of the tower column. The lattice steel truss tower cable-stayed bridge is characterized in that the tower column comprises four box-shaped steel columns, a T-shaped rib is arranged in the tower column, a supporting structure composed of linear cross braces and X-shaped diagonal braces and connects the four box-shaped steel columns into a whole, and the tower top crossbeam is of a steel truss structure and connects two independent tower columns together. A stressed mode of a main tower is improved to achieve the objective of fully utilizing strength of steel.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering design, in particular to a cable-stayed bridge with steel truss towers in lattice structure. Background technique [0002] With the rapid development of my country's economy and technology, the speed of infrastructure construction is accelerating, especially with the improvement of bridge engineering construction technology, more and more urban bridges use high standards, large spans, and new types as the link between urban areas. To facilitate people's travel. The goal of urban construction is "blocking". The traditional long-span bridge construction in my country uses reinforced concrete as the main building material. The construction period is long, and the pollution of production materials is serious. It has a serious impact and greatly reduces the happiness index of urban residents. [0003] The existing steel towers of cable-stayed bridges are mainly box-shaped, and concrete is po...
