Composite floor with steel bar trusses, profiled steel plate and regenerated concrete, and manufacturing method for composite floor

Abstract

The invention relates to a composite floor with steel bar trusses, a profiled steel plate and regenerated concrete, and a manufacturing method for the composite floor. The composite floor mainly comprises the profiled steel plate, the regenerated concrete poured on the profiled steel plate, the inclined grid type steel bar trusses and transversely distributed bars, wherein the profiled steel plate is paved on a steel beam of a steel structure main body; the bottom of the profiled steel plate is fixedly connected with the steel beam; each inclined grid type steel bar truss is arranged on each wave groove or isolation groove of the profiled steel plate and consists of a snake-shaped steel bar, a plate bottom stressing bar and an upper longitudinal steel bar which are welded with one another; and the transversely distributed bars are arranged on the inclined grid type steel bar trusses and are connected to the inclined grid type steel bar trusses in a bound manner. By the composite floor, the anti-shearing bearing capacity of the inclined section of a composite plate can be improved; and the composite floor is suitable for industrial and civil buildings with relatively high requirements on the bearing capacity of floors.

Description

technical field [0001] The invention relates to a truss with steel bars-profiled steel plate-regenerated concrete composite floor and a manufacturing method thereof, belonging to a composite floor and a manufacturing method thereof. Background technique [0002] In recent years, profiled steel plate-concrete composite floors have been increasingly used in industrial and civil buildings. The profiled steel plate in the composite floor slab of profiled steel-concrete can also serve as a permanent formwork during the construction stage, and can also be used as a working platform, which is convenient for construction and shortens the construction period; Working together produces a combined effect. Recycled concrete technology can realize the reuse of construction waste and protect the environment while saving resources. It is one of the main measures to achieve sustainable development of buildings, resources and the environment. [0003] In general, the ultimate bearing capac...

AI Technical Summary

Problems solved by technology

[0003] In general, the ultimate bearing capacity of profiled steel plate-concrete composite floors is controlled by the flexural bearing capacity of the normal section and the longitudinal shear bearing capacity of the superimposed surfaces. Under the action of load, it is easy to occur the shear failure of the oblique section at the maximum shear force of the support
