However, the grim thing is: my country's current stockpile of phosphogypsum has exceeded 500 million tons, and the new stockpiles are 60 million tons every year. The newly increased phosphogypsum needs to occupy about 5,000 hectares of land. The stockpiling of a large amount of phosphogypsum is very

Abstract

The invention discloses a profiled steel sheet-ardealite-calcium silicate board composite floor and a manufacturing method thereof. The manufacturing method comprises the steps that a profiled steel sheet and C-shaped connecting pieces are blanked according to design requirements, and the C-shaped connecting pieces are mounted on the top surface of the profiled steel sheet through self-tapping screws; after all the C-shaped connecting pieces are mounted, the profiled steel sheet with the C-shaped connecting pieces is mounted on a floor beam, and then ardealite slurry is poured; after the ardealite slurry is formed and reaches the strength and the water content required by the design, the calcium silicate board is mounted on the top surfaces of the C-shaped connecting pieces by using special screws for mounting the calcium silicate board. The composite floor gives play to the ardealite filling performance, and the buckling failure risk of the profiled steel sheet is reduced; the strength performance of the ardealite is exerted, and the bearing capacity and the deformation capacity of the floor are improved; the heat preservation, thermal insulation and fire resistance of the ardealite are exerted, and the thermal performance and fireproof ability of the floor are improved; and in addition, application of the ardealite in the floor can further open up a new direction for resourceutilization of the ardealite.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a profiled steel plate-phosphogypsum-calcium silicate board composite floor and a manufacturing method thereof. Background technique [0002] Composite slabs are a form of slabs commonly used in steel structures. In the heavy steel structure, the composite floor is mainly composed of profiled steel plate and concrete. During construction, profiled steel plates are first laid on the steel beams, and the steel plates are fixed on the steel beams with cylindrical head welding nails, which are used as shear connectors for the composite floor slab. Subsequently, the reinforcement mesh sheet is laid and the concrete is poured. The biggest advantage of this composite floor is: 1. The profiled steel plate can be used as a formwork when pouring concrete, which reduces the workload of setting up supports and laying formwork during construction; 2. The profile...
