5, lifting the plate to rise the layer; one of the plate column structure systems, but the construction method is different.
In reference to the above, the existing method for processing a part of prefabricated parts is to pour raw materials into a manufacturing mold, maintain and dry for a suitable time, and then take out the prefabricated parts from the manufacturing mold.
However, the existing prefabricated member forming and processing equipment for the fabricated building has some problems, for example, the concrete manufacturing and the prefabricated member forming belong to two different independent equipment, and the integration level is not high; uneven pouring is easy to occur during concrete pouring; in addition, the existing molding processing equipment is inconvenient for demolding.
Therefore, the inventor designs a prefabricated part forming and processing device and a processing method for an assembly type building, which are used for solving the problems.
