Vertical forming method of concrete panel

The present invention relates to a concrete panel vertical forming method for efficiently forming, at once, a number of various concrete panels including concrete slats or the like on the floor of a pig house. A plurality of molding plates (100) are stood to be vertically in close contact with each other on a base plate (B) and concrete mortar (M) is injected into a cavity between the molding plates (100) from the top thereof and cured. Next, by separating the molding plates (100) that have been in close contact, a concrete panel including, at a time, a plurality of concrete slats (1) is formed. The molding plates (100) are formed with molding projections (120, 130) for forming slits or holes on the left and right sides of a plate body (110), and sidewalls (140, 150) are formed vertically on the left and right side surfaces thereof, so that when the molding plates (100) are stood on the base plate (B), the molding projections (120, 130) and the sidewalls (140, 150) are in close contact with each other. After making the molding plates (100) come into close contact with each other by using a clamp (C), concrete mortar (M) is filled and cured in the cavity between the molding plates (100). Next, the molding plates (100) are separated to demold the concrete panel.
