Abstract

The invention relates to the technical field of cable-stayed bridges and relates to a steel-concrete cable-stayed bridge tower tip. The steel-concrete cable-stayed bridge tower tip comprises a steel tower tip body, a concrete structure and a connecting structure; the end face, near the concrete structure, of the steel tower tip body, is provided with a horizontal partition plate; the concrete structure is fixed with the steel tower tip body through the connecting structure; the connecting structure comprises a first mounting assembly fixed to the steel tower tip body, a second mounting assembly fixed to the concrete structure, and the connecting assembly arranged between the first mounting assembly and the second mounting assembly, wherein the connecting assembly is obliquely arranged relative to the horizontal partition plate, and the first mounting assembly is provided with an adjusting plate attached to the horizontal partition plate. According to the steel-concrete cable-stayed bridge tower tip, the connection strength of the steel tower tip structure and the lower concrete structure is high, and the wind load resistance of the steel-concrete cable-stayed bridge tower tip is high.

Description

technical field [0001] The invention relates to the technical field of cable-stayed bridges, in particular to a spire of a steel-concrete cable-stayed bridge. Background technique [0002] The main tower of the cable-stayed bridge is generally a concrete structure, and the spire is located at the top of the main tower of the cable-stayed bridge. From the perspective of the landscape, special modeling treatment is often carried out to highlight its symbolism. Due to the high distance from the spire to the ground, if a concrete structure is used, the process of formwork processing, installation, and on-site pouring will be more difficult, and it will be difficult to guarantee the construction period and construction quality. At the same time, due to the constraints of construction conditions, it will be difficult to achieve breakthroughs in shape; If the aluminum plate is used for decoration, the safety is difficult to be guaranteed due to the high wind speed at the spire. Fo...
