Composite floor jointly stressed by corrugated steel and cast-in-place reinforced concrete

Abstract

The invention provides a composite floor jointly stressed by corrugated steel and cast-in-place reinforced concrete, and is mainly used in the field of architectural engineering. The composite floor is high in construction speed and simple in working procedure; the composite floor is mainly composed of a corrugated steel 1, an anchor steel bar 2, a steel tie bar 3, and cast-in-place reinforced concrete 6; the main working principle is that when the floor bears an external load, the anchor steel bar 2 can prevent the part between the corrugated steel 1 and the cast-in-place reinforced concrete reinforced 6 from slip and separation, wherein the corrugated steel 1 plays the role of a stressed steel bar at the moment; left and right webs 7 of the corrugated steel 1, a lower wave plate 8 and the cast-in-place reinforced concrete 6 are combined into a reinforced concrete joist, the steel tie bar 3 ties the left and right webs 7 of the corrugated steel 1, thus when the reinforced concrete joist bears the external load on the floor, the cast-in-place reinforced concrete 6 cannot deform, in fact, the left and right webs 7 and the lower wave plate 8 play the role of stirrup of a reinforced concrete beam, and therefore, the corrugated steel 1 and the cast-in-place reinforced concrete 6 can completely jointly work and resist external force.

Description

technical field [0001] The invention is mainly used for cast-in-place floor slabs in the field of construction engineering. Background technique [0002] At present, the construction process of cast-in-place slabs in the field of construction engineering is: laying the slab base formwork - installing binding steel bars on the base formwork - pouring concrete - dismantling the slab base formwork - plastering and whitewashing the bottom of the slab and other decoration processes. The process is cumbersome and time-consuming. . Contents of the invention [0003] The present invention overcomes the above-mentioned shortcomings. It has fast construction speed, simple process, and under the same cross-sectional area, its strength and rigidity are much greater than ordinary floor slabs; It is composed of tie bars (3), longitudinal main bars (4), transverse bars (5), cast-in-place concrete (6), and longitudinal joint plates (12); the corrugated steel plate (1) consists of multipl...
