Problems solved by technology

[0002] At present, hydraulic climbing formwork is generally used in the construction of high-pier cable towers of bridges. When the cable towers are double-legged, the distance between the tower columns becomes larger or smaller, and the formwork generally adopts hydraulic climbing formwork with external cantilever platforms. Temporary platforms are used for the steel bar binding platform, which has high safety risks, long construction period and low efficacy

Abstract

The invention provides a variable-width platform device for quickly constructing the hydraulic climbing formwork of a double-limb cable bent tower and a construction method. The device comprises an embedded part; a wall attaching device is fixedly mounted on the embedded part; a vertical guide rail is fixedly mounted on the outer side wall of the wall attaching device; a hydraulic climbing formwork device is installed on the vertical guide rail; an operation platform is fixedly installed at the top of the hydraulic climbing formwork device; a formwork system is installed at the top of the operation platform through a transverse sliding device; a tower column on one side where the formwork system is located is connected with a formwork system on the other side of the double-limb tower column through a distance adjusting device. The device is a large construction platform device specially aiming at the conditions that a hydraulic climbing formwork on the inner side of the tower column ofa cable bent tower is insufficient in operation space, is not provided with a steel bar binding platform or is provided with a platform insufficient to guarantee steel bar binding safety.

Description

technical field [0001] The invention relates to a variable-width platform device and a construction method of a hydraulic climbing formwork for rapid construction of double-leg cable towers, and belongs to the field of bridge construction devices. Background technique [0002] At present, hydraulic climbing formwork is generally used in the construction of high-pier cable towers of bridges. When the cable towers are double-legged, the distance between the tower columns becomes larger or smaller, and the formwork generally adopts hydraulic climbing formwork with external cantilever platforms. The steel bar binding platform adopts a temporary platform, which has high safety risks, long construction period and low efficacy. Contents of the invention [0003] The purpose of the present invention is to provide a widening platform device and construction method for rapid construction of the hydraulic climbing formwork of the two-legged cable tower. This device is specially aimed...
