Description
Technical Field
The invention relates to preparation of a concrete prefabricated member, in particular to a ceramsite foam concrete prefabricated member production mold and a concrete prefabricated member production method.
Background
The housing industrialization is a premise of the housing industrialization development, and the concrete prefabrication technology is one of the ways for realizing the housing industrialization. With the development of housing industrialization, the application of precast concrete technology is wider and wider, more and more high-precision precast concrete component products emerge, and the precast concrete components are developing towards standardization and automation.
Because the production of the concrete prefabricated part is carried out under the conditions of standard operation and strict monitoring and necessary auxiliary facilities are cooperatively completed, the produced product has better quality stability and superiority than a cast-in-place structure. The high efficiency, high quality, low resource consumption and low environmental impact of the residential building are realized through the concrete prefabrication technology, and the concrete prefabricated building has remarkable economic benefit and social benefit and is the development trend of the current residential building.
The ceramsite foam concrete takes ceramsite or (and) ceramic sand as aggregate, bubbles prepared by a physical or chemical foaming mode are introduced into a mixture, and then the mixture is cast, molded and maintained at normal temperature to form the porous material with higher strength and heat preservation performance. Because the inside of the ceramsite foam concrete contains a large number of pores, the dry density of the ceramsite foam concrete is low, and the ceramsite foam concrete can effectively reduce the self weight of a building when being used as a concrete prefabricated part material.
The conventional preparation process of the ceramsite foam concrete comprises two steps: in the first step, ceramsite, cement and water are stirred into a uniform mixture with certain fluidity, and in the second step, the mixture is mixed with foam and then poured into a mold, and the ceramsite foam concrete is formed after maintenance. The method is easy to cause the floating of the ceramsite, so that the compressive strength and the heat insulation effect of the ceramsite foam concrete are not uniform and are adversely affected.
In order to solve the above problems, the invention patent of CN201610621812.7 in the prior art proposes a production process of ceramsite foam concrete prefabricated member, which directly places the unmixed ceramsite in the mold, realizes mixing while grouting the bottom, and prevents the ceramsite from floating upwards through the pre-compacting method and the resisting action of the top cover, thereby making the ceramsite distributed uniformly and improving the performance of the concrete prefabricated member. However, the method does not fully stir and mix the ceramsite and other ingredients, and the ceramsite floats upwards while being mixed, and the problem that the ceramsite is not uniform at the upper part and the lower part still exists.
