Embodiment Construction

[0026] 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 implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0027] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

Abstract

The invention discloses a cable bent tower and a leaning tower cable-stayed bridge. The cable bent tower comprises a first tower column, a second tower column and a tower base, wherein the first towercolumn is mutually connected with the second tower column, and the first tower column and the second tower column are installed on the tower base. One or more installation holes are formed in the first tower column and used for a stayed cable to penetrate in; one or more first cable fixing pieces and one or more second cable fixing pieces are arranged on the second tower column. By adding the first tower column and connecting the first tower column with the second tower column, when the stayed cable produces a tension force towards the middle of a main beam on the second tower column, the first tower column can produce a supporting force in the opposite direction on the second tower column so as to nullify the tension force of the stayed cable on the second tower column, the stress of thecable bent tower is more balanced and stable, the problem that the stress of a traditional cable bent tower is not balanced to cause bridge collapse is effectively solved, and then the cable-stayed bridge is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of cable-stayed bridges, in particular to a cable-stayed bridge and a cable-stayed bridge. Background technique [0002] Cable-stayed bridge, also known as cable-stayed bridge, is a bridge in which the main girder is directly pulled on the cable tower by many cables. a structural system. The inclined-tower cable-stayed bridge is a bridge in which the cable tower is installed obliquely on the main girder. With the continuous improvement of human pursuit of bridge architectural landscape, leaning tower cable-stayed bridges have gradually appeared in different regions. However, due to the unreasonable stress of the general leaning tower structure, it is easy to cause the overall stress distribution of the cable-stayed bridge to be unbalanced, resulting in the collapse of the entire bridge, which seriously endangers personal safety. Contents of the invention [0003] Based on this, it is necessary to provid...
