Abstract

The invention provides a template system of a prefabricated simply support box beam and is used for solving the problem that the appearance and quality of the beam body are not good caused by the influence of camber and the repeated utilization of the template in a prefabricated tool system of the conventional simply support box beam. The template system comprises a bar-type beam-fabricating pedestal (1), the prefabricated simply support box beam, a bottom template (2), a side template (3), an end template and an internal template, wherein side template connecting hinges (6) are arranged on two sides of the bar-type beam-fabricating pedestal (1), the lower end of a side template support adjusting plate (7) is articulated with the side template connecting hinges, the upper end of the side template support adjusting plate (7) is articulated with the inner end of a flange support adjusting plate (9) through a two-plate connecting hinge (8), the outside of the side template support adjusting plate (7) is arranged on an inside inclined plate of an external mode truss (5), and a bottom lifting jack (11) is arranged between the bottom end of an outside column of the external mode truss (5) and the ground. The invention provides a high-standard high-quality large-scale simply support box beam for high-speed railway.

Description

technical field [0001] The invention relates to a device for prefabricating a large simply supported box girder of a railway, in particular to a template and a prefabricated tooling system used for prefabricating a large simply supported box girder of a railway. Background technique [0002] Compared with the existing railway, the passenger dedicated line has the characteristics of high speed and high requirements for smoothness of the line. The appearance quality of the box girder is an intuitive reflection of the quality of the concrete box girder. The prefabricated box girder formwork adopts steel formwork, which is composed of bottom formwork, side formwork, end formwork and inner formwork; the formwork must have sufficient strength, rigidity and stability to ensure the size of each part of the box girder and the position of embedded parts during the construction and production process The accuracy of the template will not affect the appearance quality of the beam body ...
