The casting mould has two sides, the distance between which is adjustable without altering them in any other way. They have a number of identical metal wire stirrups located parallelto the mould side perpendicular plane so that the end points on the parts of each stirrup projecting from the mould sides into the remaining part of the mould are at some distance from each other. Corresp. stirrups in two opposite mould sides are fixed into position by U-profiles retained by screws, and are connected to each other by welding or riveting to form composite cross grids which hold the mould walls together. |
