A prefabricated laminated cavity floor

Abstract

The invention provides an assembling type overlapped cavity floor cover. The assembling type overlapped cavity floor cover comprises columns, a main beam, an auxiliary beam, upper-flange-free cavity plate components and cast-in-situ reinforced concrete floor cover upper flange plates. The assembling type overlapped cavity floor cover is characterized in that the auxiliary beam is arranged in a column net formed by the columns and the main beam; the upper-flange-free cavity plate components are arranged on a framework of the auxiliary beam; the assembling type upper-flange-free cavity plate components and the beams are arranged in a vertical or horizontal overlapping manner, the vertical overlapping manner is to overlap the assembling type upper-flange-free cavity plate components to the top surfaces of the beams, and the horizontal overlapping manner is to overlap the assembling type upper-flange-free cavity plate components to the horizontal surfaces of the beams; and reinforced concrete is poured on the upper surfaces of the upper-flange-free cavity plate components to form assembling type cavity floor cover upper flange plates through overlapping, so as to form the assembling type overlapped cavity floor cover.

Description

technical field [0001] The invention relates to a prefabricated building system technology, in particular to a prefabricated superimposed cavity floor technology. Background technique [0002] In the 1980s, the production of concrete prefabricated components in my country was in a stage of great development. In the process of housing construction, the country used hollow prefabricated slab structures, large slab structures, cast-in-place concrete structures, cast-in-place concrete hollow floor slab structures, and cast-in-place concrete frame structures. , cast-in-place concrete frame shear wall structure, etc. With the industrialization process of housing, steel-concrete composite structure and steel-concrete composite cavity floor structure system have been developed rapidly. Longitudinal laminated slabs, that is to say, laminated fabricated solid slabs on top of the beams. [0003] For example, ZL200410082381.9 "a fasting small ribbed floor" declared by the inventor, the h...

Problems solved by technology

[0007] The purpose of the present invention is to promote the progress of building science and technology, organically combine the industrially produced prefabricated assembly-type cavity plate components without upper flanges with the reinforced concrete beams and columns poured on site to form an assembly-type laminated cavity floor, which adopts horizontal Superposition can also save the benefits generated by the floor space occupied by the exposed beams, and optimize the existing frame structure technical system; make full use of the advantages of industrialization of the factory, prefabricate and produce assembly-type upper-flange cavity plate components, and solve the weight of the components , Poor structural integrity, difficult implementation controllability, environmental pollution caused by on-site construction, heavy quality, high construction cost, slow progress of the project, a large number of building formwork and steel supports, resulting in long mold making time and affecting the construction speed, etc.
