Abstract

The invention discloses a stiff skeleton structure for bridge closure. The stiff skeleton structure comprises a skeleton body and a locking device, wherein the skeleton body is composed of a pluralityof supporting structures, each supporting structure consists of a first transverse rod, a second transverse rod, a first longitudinal rod, a second longitudinal rod, an inclined rod, a first main inclined support and a second main inclined support; the locking device is arranged on the skeleton body, the locking device is used for being fixedly connected with the end part of a bridge closure section. The stiff skeleton is good in stress stability and high in reliability.

Description

technical field [0001] The invention relates to the technical field of bridge construction. More specifically, the present invention relates to stiff skeleton structures for use in bridge closures and methods of construction thereof. Background technique [0002] Bridges are very important components of traffic lines, especially in the construction of high-grade highways, railways and urban elevated roads, bridges are often the key structures to ensure the opening of the entire line. With the advancement of science and technology and the improvement of industrial level, bridge construction technology has developed rapidly, and gradually formed a three-dimensional traffic network in my country, which greatly improved the current traffic situation and promoted the development of the national economy. Among them, the span cable-stayed bridge is a high-order statically indeterminate structural system with high tower columns and large girder spans. In order to ensure the qualit...
