Prefabricated three-hinged-arch roof panel and mounting method

Abstract

The invention relates to the technical field of buildings, in particular to a prefabricated three-hinged-arch roof panel. The prefabricated three-hinged-arch roof panel comprises multiple sets of roofpanel bodies arranged at angles, each set of roof panel bodies comprise two prefabricated plates (or light steel framed wallboards, composite wallboards and the like), one ends of the two prefabricated plates of each set of roof panel bodies are hinged to each other, the other end of each prefabricated plate is obliquely downwards arranged and hinged to a wall board, the opposite side faces of the two prefabricated plates of each set of roof panel bodies are fixedly connected through a prefabricated plate connecting piece, a ridge is formed at a mutually-hinged position of the prefabricated plates, one end of each prefabricated plate is provided with an inclined face, a groove is formed in each inclined face, two lug plates are fixedly arranged in each groove, and the correspondingly arranged lug plates on the two prefabricated plates of each set of roof panel bodies are hinged through a bolt pin. According to the prefabricated three-hinged-arch roof panel, rapid mounting and dismounting of the roof panel in a rapidly-mounted integrated house can be achieved, the structural stability of the roof panel is high, the heat preservation and energy saving effects are good, and cycle usecan be achieved.

Description

technical field [0001] The invention belongs to the technical field of buildings, and in particular relates to a prefabricated three-hinge arch roof panel and an installation method. Background technique [0002] At present, mobile houses are mainly divided into integral container houses and color steel prefab houses. The roof panels and wall panels of the overall container house are all steel plates, which are welded and cannot be disassembled, and the transportation cost is high; the wall panels and roof panels of traditional color steel houses have poor thermal insulation performance, and the color steel plates and steel skeletons use self-tapping screws connection, low recyclability. In view of the above shortcomings, the present invention provides a prefabricated three-hinge arch roof panel with low cost, convenient disassembly and superior performance and its installation method. Contents of the invention [0003] The invention provides a prefabricated three-hinge ...
