Description

Technical Field

[0001] The present invention relates to the technical field of cable tower construction, and more specifically, to an integrated hoisting platform and a construction method for cable tower decorative component construction. Background Art

[0002] A cable tower refers to a tower-shaped structure that supports the main cable of a suspension bridge or a cable-stayed bridge. The cable tower is the basic load-bearing component and an important part of a cable-stayed bridge. It not only bears its own weight and the weight of the main beam bridge deck system transmitted through the cable, but also bears the vertical load and horizontal load caused by the bridge deck system. Common cable tower forms include single column, A-shaped and inverted Y-shaped. In order to avoid the single shape of the cable tower, designers will set decorative components outside the cable tower to make the cable tower more unique and beautiful. The cable tower is usually high, and the construction of the external decorative components of the cable tower is difficult and the risk of hoisting is high. At present, the conventional construction methods are: 1. A special attached working platform is set on the upper tower column, and the lifting equipment hoists the decorative components into place for installation; 2. Occupy another lifting platform for lifting equipment, and the lifting equipment hoists the decorative components into place for installation. However, in the special-shaped cable tower structure, its spatial curve is complex, the structural size changes nonlinearly, and there are huge differences in the size of the decorative components. The installation space is narrow, and the conventional installation method has the following shortcomings:

[0003] (1) Ladders cannot be arranged due to limited space, and the attached work platform cannot be used for personnel to transfer during installation, which requires unnecessary manpower;

[0004] (2) Setting up and dismantling the attached work platform is time-consuming and labor-intensive, the risk of high-altitude installation and dismantling is huge, and embedded parts are difficult to repair;

[0005] (3) The work platform and the decorative components are hoisted separately, which will occupy extra lifting equipment and have certain requirements on their lifting capacity;

[0006] (4) The sizes of decorative components vary greatly, and a single-size work platform cannot meet their needs. It takes a lot of time and materials to process a platform that matches the size. Summary of the invention
