Abstract
Abstract A method and carrier members for the formation of building elements of the type having a plurality of bricks, tiles or stones joined together by a binder. A plurality of carrier members, having slightly elastic side edges partially surrounding the side edges of bricks inserted into said carrier members, are positioned in a mold in their ultimate relationship as in the completed building element. Thereafter a bonding material is filled into the spaces defined between said carrier members to form the completed building element. In this way said carrier members may be filled before their arrangement in the mold and are thus also usable as a transportation package.
