A prefabricated large modular composite beam-slab structure with planar truss temporary support

Abstract

The invention discloses a fabricated large-module composite beam-slab structure with plane truss temporary supports. The fabricated large-module composite beam-slab structure comprises a beam, the temporary supports, beam connecting plates, a steel bar net and a prefabricated concrete layer; after the beam and the connecting plates are welded, the beam is in bolt connection with a truss to form atemporary whole; steel bar net slices are laid on the temporary whole, steel bars extend to be connected with a flange of the beam in a welded mode, and a concrete slab layer is poured to form the fabricated large-module beam-slab structure; and after on-site hoisting in position is completed, the upper layer of steel bars is laid, and remaining concrete is poured. The fabricated large-module composite beam-slab with the temporary supports are adopted to solve the problem of wholeness of a floor slab; as the large-module beam-slab structure integrates the beam with the slab, the problem of connecting of the beam and the slab is solved; by adopting the steel bar net slices, manufacturing is simple and convenient, and arrangement of late pipelines is facilitated; and the hoisting weight is reduced, and the assembling precision and construction efficiency are improved.

Description

technical field [0001] The invention relates to an assembled large module laminated beam-slab structure with temporary support of plane trusses, belonging to the technical field of structural engineering. Background technique [0002] Prefabricated buildings are the focus of development in my country's construction industry for a period of time in the future, and the innovation of industrialized prefabricated structural systems is imperative. The prefabricated structural system refers to the building produced by making housing units or components according to uniform and standard building part specifications, and then transporting them to the construction site for assembly in place. A large number of building parts are produced and processed by the workshop, a large number of assembly operations on site, standardization of design and informatization of management meet the requirements of green buildings. It is characterized by light building weight, energy saving and enviro...
