Description

Technical Field

[0001] This utility model relates to the field of steel model processing technology for precast concrete simply supported beams, and more specifically, to a steel model processing device for precast concrete simply supported beams. Background Technology

[0002] A simply supported beam is a beam whose two ends rest on supports, which only constrain the vertical displacement of the beam, allowing the beam ends to rotate freely. To prevent the entire beam from moving horizontally, a horizontal constraint is added at one end; this support is called a hinged support, while the support at the other end without horizontal constraint is called a rolling support. A simply supported beam is a structure where the supports at both ends only provide vertical constraints and do not provide angular constraints. There are two methods for manufacturing simply supported concrete beams: in-situ casting and factory prefabrication. In-situ casting is an older method where scaffolding and formwork are erected at the bridge site, concrete is poured on the scaffolding, and after it reaches strength, the formwork and scaffolding are removed, ultimately forming a simply supported concrete beam. Its disadvantage is that it requires a large number of formwork and scaffolding, making it unsuitable for remote areas. Factory prefabrication, on the other hand, involves transporting pre-made beams to the construction site, installing and erecting them using specific methods. Factory production ensures high-quality components, helps guarantee component quality and dimensional accuracy, utilizes mechanized construction, and allows for rapid construction.

[0003] The production of simply supported concrete beams in factories requires the use of steel models, which consist of several steel templates. During the production process, the steel structure needs to be cut and processed. In the existing technology, during the processing of steel models for prefabricated simply supported concrete beams, especially during the cutting and processing of the steel structure, there is still a situation where workers have to lift the steel templates, which is not only labor-intensive but also poses a safety hazard of the steel templates falling.
