Abstract

The invention relates to a replaceable prefabricated combined beam structure which comprises a steel beam, prefabricated concrete plates and high strength bolt connectors. The prefabricated concrete plates are located on upper wing edge plates which are parallelly arranged on the steel beam, and adjacent prefabricated concrete plates in a span direction are connected through an external prestressing tendon; lower holes corresponding to the high strength bolt connectors are formed in the upper wing edge plates of the steel beam, reserved holes corresponding to the connectors are formed in the prefabricated concrete plate, and the high strength bolt connectors are connected through the reserved holes and the lower holes from top to bottom. The invention also provides a manufacturing process of the replaceable prefabricated combined beam structure. The invention provides the replaceable prefabricated combined beam structure which is simple to construct and relatively high in assembling efficiency, and the manufacturing process.

Description

technical field [0001] The invention relates to a replaceable prefabricated composite beam structure and a manufacturing process, belonging to the technical field of bridge engineering. Background technique [0002] The "13th Five-Year Plan" of the transportation industry proposes to actively promote the industrialized production of bridges, and the development of prefabricated bridges is a major way to realize the industrialization of bridges. At present, domestic prefabricated concrete structures are adopted by some engineering projects due to their advantages such as fast construction speed and high quality level. However, due to their disadvantages such as high production costs, difficult construction and non-removable modification, they cannot meet the design or construction requirements in many building forms. , which largely limits the development of prefabricated concrete structures. [0003] Steel-concrete composite beam is a structural system composed of steel bea...
