Description
Technical Field
The utility model relates to the technical field of bridge engineering, in particular to a connecting structure of a round steel tube concrete truss bridge.
Background
The traditional truss combined beam is formed by connecting concrete with a truss through bolts to form an integral structure. Usually, a steel bottom die is used as a template for pouring concrete, but the poor bonding capability between the steel bottom die and the concrete often influences the overall stress condition of a truss girder bridge, and the problem of connection between the steel bottom die and an upper chord of a truss also leads to poor overall performance of the structure and complex construction. Secondly, the cross-sectional forms of the current trusses vary widely, and the most used or round steel pipe concrete trusses are introduced in practical examples. Considering that the bolt is extremely easy to generate dislocation and cause shearing damage when the regular profiled steel sheet is connected with the round steel tube concrete, the application of the waveform steel sheet is considered.
