Abstract

The invention provides a cable bent tower beam light-weight support design and construction method. The method comprises the specific steps: dividing all pouring layers of a cable bent tower beam, and determining the height of each pouring layer; preliminarily drawing up the structural form of the cross beam support and the type and parameter of the support section; determining a support structure design load; re-determining the section type and parameters of the support, and comparing the section type and parameters with the preliminarily prepared result; repeating the previous two steps until the deviation of the front and back comparison of the load value borne by the support does not exceed the limit value N%; mounting a support structure on site, and making support observation preparation; carrying out a support pre-pressing experiment; and alternately carrying out cross beam layered pouring and support observation, and completing cross beam pouring. Compared with the traditional method, the method can reduce the material consumption of the cross beam bracket, and realizes cost reduction and benefit increase; a design mode of multi-time simulation and optimization is adopted, so that the design precision is ensured, and the safety is improved; and the method is suitable for various layered pouring construction, and the application range is very wide.

Description

technical field

[0001] The invention relates to the technical field of bridge construction, in particular to a design and construction method of a light-weight support for a cable tower beam. Background technique

[0002] The beams of the cable towers of long-span bridges are generally cast in layers. For the design and construction of the beam support, traditional methods use the dead weight of the entire beam plus live loads such as personnel and tools as the design load. The traditional method fails to make full use of the "portal rigid frame", that is, the beam structure that is poured first and the two-leg tower columns form the self-carrying capacity of the portal structure, which leads to unreasonable design of the beam support structure, resulting in the failure of the support structure. The design load is much larger than the actual load, resulting in a waste of resources. Contents of the invention
