A prefabricated concealed beam floor

Abstract

The invention provides an assembly type hidden beam floor system. The assembly type hidden beam floor system comprises columns, main beams, secondary beams, assembly type cavity plate components and cast-in-place reinforced concrete floor system upper flange plates and is characterized in that the secondary beams are arranged in a column net formed by the columns and the main beams and are located on the same horizontal plane with the assembly type cavity plate component lower flange plates; the assembly type cavity plate components are installed in a secondary beam frame; each assembly type cavity plate component ribbed beam is formed by pouring a lattice girder, a hole forming component and concrete; assembly type cavity plate component upper surface rebars penetrate through beam rebars and form an assembly type cavity floor system upper flange plate with beam simultaneous pouring concrete; and the assembly type hidden beam floor system is constructed.

Description

technical field [0001] The invention relates to a prefabricated building system technology, in particular to a prefabricated concealed beam floor technology. Background technique [0002] In the 1980s, the production of concrete prefabricated slab components in my country was in a stage of great development. Due to the overall poor quality of concrete prefabricated slab components, the use of them was prohibited; the country promoted the use of large slab structures, cast-in-place concrete structures, Cast-in-place concrete hollow floor structure, cast-in-place concrete frame structure, cast-in-place concrete frame shear wall structure, etc.; with the process of housing industrialization, recently, steel-concrete composite structure and steel-concrete composite cavity floor structure system have been obtained With rapid development, my country's prefabricated floor has just started, using longitudinal laminated slabs, that is to say, prefabricated large slabs are laminated on ...

AI Technical Summary

Problems solved by technology

Constitute a prefabricated concealed beam floor, save the benefits generated by the floor space occupied by the exposed beams, and optimize the existing frame structure technology system; make full use of the advantages of industrial prefabricated production of assembled cavity plate components, and then integrate the existing technology The longitudinal superposition relationship between the beam and the prefabricated laminated slab is optimized, and the prefabricated laminated slab is superimposed in the horizontal direction of the beam to realize the prefabricated concealed beam floor, which not only improves the overall safety of the building, but also solves the problem of existing problems. Longitudinal stacking of slabs, stacked on top of the beams to form a building structure with exposed beams, resulting in exposed beams occupying the height between floors, difficult implementation controllability, environmental pollution caused by on-site construction, heavy quality, high construction costs, slow progress of the project, and a large amount of Building templates and steel supports lead to a series of defects such as long molding time and affecting the construction speed
