Technical Field
The utility model relates to a bridge engineering technical field, in particular to steel truss connects with interim scalable member device.
Background
In recent years, steel structure bridges in China develop rapidly, on one hand, the steel manufacturing process, the steel quality and the anticorrosion technology are improved continuously, and on the other hand, the steel structure bridges are benefited from the increasing maturity and development of the technologies in the aspects of fatigue, welding, vibration, design and construction of bridge structures and the like. The underprop type simply supported steel truss bridge has the characteristics of light dead weight, strong spanning capability, low building height, high construction speed and the like, and is one of common railway bridge types.
The simply supported steel truss bridge is generally prefabricated and assembled and is constructed in an integral pushing mode. For the multi-span simply supported steel truss bridge, the multi-span simply supported steel truss bridge can be connected together through the temporary truss rod piece, a simply supported structure is changed into a continuous structure state, and the whole simply supported steel truss bridge is pushed together. After the pushing is in place, the temporary connection rod pieces of the truss are removed, the continuous structure is changed into a simply supported structure state, and the multi-span simply supported steel truss bridge is formed. The temporary member is used for integrally connecting the upper chord nodes and the lower chord nodes of the multi-span simple steel truss bridge, so that the front-span steel truss structure and the rear-span steel truss structure can be used as the front-guide beam structure and the rear-guide beam structure, the front-guide beam structure and the rear-guide beam structure are not required to be arranged for the incremental pushing construction of the simply-supported steel truss, the incremental pushing can be in place at one time, the erection of the multi-span simple steel truss bridge formed by the temporary member is eliminated, and the construction mode of changing simple support into continuous support is more economic and reasonable, and the construction is more convenient.
