Abstract

The invention discloses a compact stay cable steel anchor beam and a construction method thereof. The steel anchor beam comprises a steel straining beam mechanism, beam end steel anchoring mechanisms and a stay cable anchor head bearing mechanism, wherein the steel straining beam mechanism, the beam end steel anchoring mechanisms and the stay cable anchor head bearing mechanism are matched to form the novel stay cable steel anchor beam. The construction method comprises the steps of (1), assembling the steel anchor beam; (2), hoisting the steel anchor beam; (3), after the steel anchor beam is hoisted to the position, relieving and removing hoisting equipment and installing the steel anchor beam; (4), binding steel bars of a tower column, installing templates and pouring the tower column. The steel anchor beam is simple and compact in structure, convenient to construct, low in construction cost, high in safety and long in service life. The construction method has the advantages that construction is convenient, the construction cost is low and the construction efficiency is high.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of bridge components, in particular to a compact cable-stayed steel anchor beam and a construction method of the compact cable-stayed steel anchor beam. Background technique [0002] The anchor connection structure on the cable-stayed tower of the cable-stayed bridge is directly related to the normal work, safety and durability of the cable-stayed cable in the use stage, and is the focus of attention in the design of the cable-stayed bridge. The steel anchor beam is a commonly used anchor connection structure on the cable-stayed tower. The first application of the steel anchor beam is the Annacis Bridge in Canada, which was built in 1986. It was first used in Shanghai in 1991. Huangpu Jiangnanpu Bridge. The basic principle of the steel anchor beam is to separate and decouple the horizontal force and the vertical force by separately setting the steel tie beam connected horizontally ...
