Description

Large-scale high-altitude load-bearing cantilever beam device

technical field

The utility model relates to the technical field of construction tools or other construction auxiliary equipment for industrial building structure engineering and its application, in particular to the technical field of preparation, transportation or processing of building materials or building components on site, and specifically to large-scale high-altitude load-bearing cantilever beams device.

Background technique

Due to technological requirements, some cantilever beams are often designed in tall frame structure projects of industrial buildings, some of which are large load-bearing cantilever beams. A cantilever beam is not supported at both ends, but one end is buried or poured on the support, and the other end protrudes or picks out the support. The existing common cantilever beam construction method is to erect floor support formwork construction, which is suitable for the construction of small cantilever beams with lower floors. When constructing an independent large-scale load-bearing cantilever beam with a high position, due to the large load and high height of the cantilever beam, the requirements for the formwork, scaffolding and foundation are very high, which results in high construction costs and low efficiency. Moreover, when the height is super high, the construction risk factor is very high, and there are serious safety hazards.
