Abstract
The invention discloses a mechanical template system of a curved magnetic levitation track beam and an application method of the mechanical template system. The mechanical template system comprises a bottom template, a lateral template, end templates and a plurality of regulating components, wherein the bottom template is used for bearing the track beam; the lateral template comprises bendable lateral template panels, the bendable lateral template panels are arranged along two longitudinal sides of the track beam, and a plurality of frameworks are arranged on the outer side of each lateral template panel; the end templates are arranged along the end part of the track beam, and each of the end templates is provided with a translation assembly which can translate the end templates along the track beam in the longitudinal direction; each regulating component comprises at least two mechanical push rod assemblies arranged on the outer side of each framework, and each mechanical push rod assembly is used for regulating the lateral displacement of the corresponding framework relative to the track beam and the perpendicularity of the corresponding framework relative to the bottom template. The template system comprises the bottom template, the lateral template, the end templates, a plurality of the regulating components and the translation assemblies, and is simple in structure, high in regulating efficiency and convenient to mount and dismount; after a template curve is regulated and formed, concrete is directly poured so as to form the track beam, so that the prefabricated efficiency of the track beam is improved; the application method is simple, high in accuracy and good in reliability, so that the prefabricated quality of the track beam is ensured.
