Problems solved by technology

[0004] The pylon of the existing single-tower single-cable plane suspension bridge is usually a single-column tower. On the one hand, due to the large size of the cable saddle on the top of the tower along the bridge direction, the top of the tower column often needs to be equipped with an enlarged head, which increases the construction cost. The economy is poor, on the other hand, it also affects the landscape modeling of the bridge tower

Embodiment 1

[0040] The bridge tower structure of the present embodiment, as figure 1 and figure 2 Shown, comprise foundation 42, tower body, tower top cable saddle 43 and saddle cover 44, wherein foundation 42 is positioned at bridge tower structure bottom, and it is the fixed and supporting structure of tower body; Tower body bottom is fixedly connected on the foundation 42, as figure 1 As shown, the tower body is a streamlined double-leg structure that is wide in the middle along the bridge and gradually gathers up and down. There is a distance between the middle parts of the two tower limbs 41 of the double-leg structure, and a connecting ring 45 is set between them; 45 is a ring-shaped steel structure, and the connecting ring 45 is fixedly connected to the inner surfaces of the two tower limbs 41, so that it can not only bear the horizontal component force of the two tower limbs 41, reduce the bending moment of the tower limbs 41, but also form The shape of the eyeball is improved; ...

Embodiment 2

[0046] The single-tower single-cable plane suspension bridge of the present embodiment, based on the bridge tower structure of Embodiment 1, also includes:

[0047] Main girder 1, which is horizontally fixed on the lower part of the tower body of the bridge tower structure;

[0048] The main cable 2, the two ends of which are respectively anchored to the two ends of the main beam 1, and the middle part of the main cable 2 is fixedly connected with the tower top cable saddle 43;

[0049] One end of the sling 3 is fixedly connected to the main cable 2, and the other end is fixedly connected to the main girder 1.

[0050] The single-tower single-cable plane suspension bridge of this embodiment is as follows: Figure 6 As shown, the single-tower single-cable plane suspension bridge of this embodiment will be further described in detail below with the actual project as an example.

[0051] This embodiment is a self-anchored steel box girder suspension bridge with single tower and s...

Abstract

The invention discloses a bridge tower structure and a single-tower single-cable-plane suspension bridge, and belongs to the technical field of bridge construction engineering. The bridge tower structure comprises a foundation, a tower body, a tower top cable saddle and a saddle cover which are sequentially connected from bottom to top, the tower body is of a double-limb structure in the bridge direction, a gap is reserved between the middles of two tower limbs of the double-limb structure, and the tower limbs are gradually folded up and down; and the connecting ring is arranged between the two tower limbs and is fixedly connected with the middle parts of the inner side surfaces of the two tower limbs. According to the bridge tower structure, the circular steel structure connecting rings are arranged in the middles of the inner side faces of the two tower limbs, the horizontal component force of the two tower limbs can be borne, the bending moment of the tower limbs is reduced, stress is optimized, meanwhile, an eyeball shape is formed, and the concept is ingenious. Compared with a conventional single-column-shaped bridge tower, the single-tower single-cable-plane suspension bridge is novel in modeling, good in economical efficiency and good in landscape performance and has the advantages of being simple in structure, reasonable in design and easy to manufacture.

Description

technical field [0001] The invention belongs to the technical field of bridge construction engineering, and more specifically relates to a bridge tower structure and a single tower single cable plane suspension bridge. Background technique [0002] With the continuous improvement of the social and economic level, people's demand for bridge structure is not limited to the traffic function, and the pursuit of economical efficiency and modeling landscape of bridge construction is also getting higher and higher. [0003] Due to its strong adaptability to terrain and geological conditions, beautiful design, and wide view of the bridge deck, the single-tower single-cable suspension bridge has been favored by more and more bridge builders and has become the preferred bridge type for urban bridges; among them, As the main load-bearing component of the suspension bridge, the bridge tower is also the most prominent part of the design of the bridge. When designing the bridge, it is req...
