Abstract (en)

[origin: WO9632238A1] This invention relates to a method for forming gypsum structural elements (A, B) having a thermoinsulating fill, and to a mold for using this method. A method consists in pouring gypsum slurry into a mold, the component of which before said pouring is a thermoinsulating fill in a shape of an insert (1, 2), defining a component of said gypsum element after ending the process of at least initial gypsum slurry setting, whereas a one- or multi-part insert is used, having any selected outer shapes, advantageously provided with openings. A mold (30) formed as a multi-chamber box is characterized in that the inner surfaces of the side walls (32) are lined with a plane-parallel flexible and compressible separator (40), to which dismountable, rigid liner tiles (36) adhere, determining distances between particular inner partitions (34) and the side walls (33), while the inwardly directed surface of the basis (31) is lined with a replaceable plane-parallel and imcompressible liner (39) made of material not adhering to gypsum slurry.
