Assembly-type ardealite-concrete combined wallboard and preparation and assembly methods

Abstract

The invention discloses an assembly-type ardealite-concrete combined wallboard and preparation and assembly methods. The assembly-type ardealite-concrete combined wallboard comprises a concrete frameand a precast concrete ground beam; frame beam steel bars are buried in a top beam and a bottom beam of the concrete frame correspondingly, frame column steel bars are buried in two column beams of the concrete frame correspondingly, the bottom ends of the frame column steel bars further stretch out of the bottom beam of the concrete frame, and the concrete frame is filled with an ardealite-basedcomposite gel filler; a groove with the inner surface being a rough surface is formed in the precast concrete ground beam, and steel cylinders are pre-buried in the groove; the frame column steel barsstretching out of the bottom beam of the concrete frame can be inserted into the pre-buried steel cylinders arranged corresponding to the frame column steel bars, and at the moment, part of the bottom beam of the concrete frame sinks into the groove; and the groove is filled up with cast-in-place self-compacting concrete after part of the bottom beam of the concrete frame sinks into the groove. The assembly-type ardealite-concrete combined wallboard and the preparation and assembly methods have the characteristics that vertical connection is stable, the overall anti-seismic property is good,construction is convenient, and standardization is easy.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of phosphogypsum, in particular to an assembled phosphogypsum-concrete composite wallboard and a preparation and assembly method. Background technique [0002] At present, the annual discharge of phosphogypsum in China is nearly 80 million tons, and the cumulative stockpiles exceed 500 million tons. The annual production of phosphogypsum in the world exceeds 200 million tons. The promotion and stockpiling of phosphogypsum not only causes high storage yard maintenance costs for phosphating chemical plants, but also pollutes the environment. Therefore, it is necessary to increase the comprehensive utilization rate of phosphogypsum. Gypsum releases crystal water when exposed to fire, and the resulting non-combustible insulator, anhydrous calcium sulfate, can effectively reduce the rise in ambient temperature and prevent the spread of fire. Therefore, it is defined as a non-combustib...
