Process and device for preventing bonding of autoclaved aerated concrete battens

Abstract

The invention provides a process and device for preventing bonding of autoclaved aerated concrete battens and relates to the technical field of buildings. According to the process and device for preventing bonding of the autoclaved aerated concrete battens, after a blank is horizontally cut, during bottom and top skin waste removal through turnover, flat iron is additionally mounted on a backboardof a turnover machine; and when the blank is overturned to be flat placed, due to the action of the flat iron, a cut joint of a board on the lowermost portion of the blank is slightly expanded due tothe action of gravity, air enters the cut joint, and the physical environment in the cut joint changes. Although after the blank is overturned back, the cut joint is closed again, the crystallizationstrength generated by steaming in the cut joint is greatly reduced; when a board severing machine carries out separation, the boards can be separated from the cut joint, and bonding damage is avoided. According to the process and device for preventing bonding of the autoclaved aerated concrete battens, by means of the production process of the autoclaved aerated concrete battens and machining equipment adopted needed in the production process, the rate of finished products is effectively increased and reaches 95% or above, and the production cost is reduced for enterprises.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to an adhesion-free process and device for autoclaved aerated concrete strips. Background technique [0002] At present, in the production of autoclaved aerated concrete strips (ALC) with a thickness of less than 125mm, there will be serious adhesion problems when the finished products are separated, and the adhesion parts are generally the bottom five panels. The traditional solution is to improve by adjusting the raw material parameters of the green body, the mix ratio of the green body, and controlling the cutting hardness of the green body. The effect is very poor, and the yield is generally below 80%. [0003] During the production process of autoclaved aerated concrete slab (ALC), the green body needs to be cut horizontally. Since the horizontal cutting is steel wire cutting, after cutting, the green body is under the pressure of its own weight, and the slit is closed aga...
