A prefabricated two-way force-bearing floor slab

Abstract

The invention provides an assembled type bidirectional loaded floor which comprises a column, a girder, a regenerated beam, cavity plate components, an upper floor flange plate and a joint seam. The assembled type bidirectional loaded floor is characterized by being compounded and formed by simultaneously pouring concrete on site in a rebar space of the girder, on a regenerated beam connecting part formed by horizontal frame rib beam steel bars of the cavity plate components and on surface steel nets of the cavity plate components; the regenerated beam is a frame rib beam steel bar which is used for welding the adjacent cavity plate components on site; the regenerated beam and a longitudinal reinforced concrete frame rib beam are formed into a rib beam of the assembled type bidirectional loaded floor; the cavity plate components are composed of reinforced concrete frame rib beams, surface exposed steel bars, hole-forming components and bottom flange plates; the joint seam is located on the lower surface of the assembled type bidirectional loaded floor and is discontinuous; and the joint seam does not penetrate through an upper flange plate of the assembled type bidirectional loaded floor.

Description

technical field [0001] The invention relates to a prefabricated building system technology, in particular to a prefabricated two-way stressed floor. 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 top of th...

Problems solved by technology

[0007] The purpose of the present invention is to give full play to the advantages of the prior art and overcome the disadvantages of the prior art; specifically, it is a problem between "concrete prefabricated components" and "building cast-in-place technology", the former is poor in integrity, and the latter is not strong in controllability; Combining industrialized production of prefabricated cavity slab components with cast-in-place reinforced concrete beams and columns can effectively solve the integrity of "concrete prefabricated component technology" and the controllability of "building cast-in-place technology", and fundamentally improve the construction quality. The overall safety of the building promotes the progress of building science and technology; the frame-type reinforced concrete rib beam, the hole-forming member and the lower flange plate are used to reduce the weight of the prefabricated cavity plate to a great extent. The realization of large-span buildings without exposed beams laid the foundation; in order to solve the two-way force, the one-way slab ribs were connected to form recycled beams, forming a prefabricated two-way force-bearing floor, saving the floor space occupied by open beams. Benefits, to optimize the existing frame structure technology system; make full use of the advantages of industrial prefabricated production of assembled cavity plate components, and then optimize the longitudinal stacking relationship between beams and assembled laminated panels in the existing technology, and transform them into fabricated laminated panels. The plywood is laminated in the horizontal direction of the beam to realize the prefabricated hidden beam floor, which not only improves the overall safety of the building, but also solves the problem that the existing vertical laminated panels are laminated on top of the beam to form a building structure with exposed beams, which causes the occupation of open beams. A series of defects such as the height between floors, difficulty in implementing controllability, environmental pollution caused by on-site construction, heavy quality, high construction cost, slow progress of the project, and the use of a large number of building formwork and steel supports, resulting in long formwork time and affecting the construction speed, etc.
