A method of manufacturing prefabricated building elements, which comprise a through cast-solid bottom plate (13, 27) and battens (15, 21) having an I- or T-profile projecting from the bottom plate. According to the invention an upper mold portion is applied, comprising an upper plate (42), connecting plates (43) and medium plates (39) having movable lateral covers (38), in order to form profile holes, the connecting plates constituting supporting means for the upper plates, stop means for the molding position of the lateral covers and mold portions for the batten profile holes, with filling bridge portions (29) at regular intervals, the lateral covers being movably, i.e. foldably or revolvingly or displaceably mounted on one or several of said plate types. |
