[0003] It is relatively high in the existing cable towers, and it is necessary to install a ladder on the side wall of the cable tower to climb the cable tower to carry out maintenance on the cable tower. When the existing ladder operator climbs, the operator needs to The safety rope needs to be re-fixed after a few steps, which increases the danger for the operator when climbing

Abstract
The invention relates to a cable bent tower. The tower comprises a tower body, and a climbing mechanism is arranged on the side wall of the tower body. The climbing mechanism comprises a mounting plate which is fixedly connected to the outer wall of the tower body through bolts, a pedal which is installed on the mounting plate, handrails which are installed at the two ends of the side wall of oneside of the mounting plate, mounting rods which are fixedly connected to the two ends of the upper surfaces of the handrails, anti-falling rods which are fixedly connected to the two sets of mountingrods, anti-falling rings which are connected to the anti-falling rods in a sliding mode, and anti-falling pieces which are arranged between the anti-falling rods and the anti-falling rings. The mounting plate is fixedly connected to the outer wall of the tower body through the bolts, the anti-falling rods are fixedly connected to the handrails, and the anti-falling rings are connected to the anti-falling rods in a sliding manner. An operator buckles a connecting buckle at one end of a safety rope to the anti-falling rings, under the effect of the anti-falling pieces, the anti-falling rings canonly slide to the upper ends of the anti-falling rods from the lower ends of the anti-falling rods, the operator can climb onto the tower body conveniently, the operation that the operator needs to replace the connecting position of the safety rope is reduced, and the climbing safety of the operator is improved.
Description
technical field [0001] The invention relates to bridge construction, in particular to a cable tower and a construction method for the cable tower. Background technique [0002] The cable tower refers to the tower-shaped structure that supports the main cable of a suspension bridge or a cable-stayed bridge. The height of the cable tower is usually related to the main span of the bridge. The ratio of the maximum span of the main beam to the height of the cable tower is generally 3.1~6.3, with an average of about 5.0. There are many types of cable tower structures, which are mainly selected according to the layout requirements of the cables, the width of the bridge deck and the span of the main girder. The commonly used forms of cable towers are single-column, A-shaped and inverted Y-shaped along the longitudinal direction of the bridge, and single-column, double-column, portal, oblique-leg portal, inverted V, inverted Y, A shape etc. The cross-section of the cable tower can...
