Large-span beam supporting device Technical Field The application relates to the technical field of large-span beam supports, in particular to a large-span beam support device. Background At present, in modern engineering construction, the large-span beam structure is widely applied to large-scale public buildings and infrastructure projects such as convention centers, stadiums, transportation hubs, large-span bridges and the like. Such engineering generally requires the beam to span a space of tens of meters or even hundreds of meters, and at the same time, needs to meet the core indexes such as structural bearing capacity, stability, deformation control, anti-seismic performance and the like. Along with building function diversification, modeling complicacy and span continuous increase (such as ultra hundred meters large-span bridge, no post large space venue), traditional support technology has been difficult to adapt to high load, large deformation, construction convenience and economic nature's comprehensive demand, promotes the iteration of large-span beam support technology to high-efficient, safe, lightweight direction. The long span steel beam is easy to cause welding deformation problems, residual stress and residual deformation problems, sudden fracture problems and the like during specific welding construction because of the long length, so that support operation is often required during construction. However, in the construction site, the simpler support is to select a wood pile or a common steel pipe to support the large-span beam, but the wood pile and the steel pipe are not stable and safe to support, or the steel beam with the right set size is used for supporting, so that a large amount of steel is lost, and the large-span beam is inconvenient to support.
