METHOD OF MAKING CONSTRUCTION BLOCKS WITH NATURAL ROCK OR WOOD FINISHES Russian patent published in 2008 - IPC E04C1/40 

FIELD: construction, superstructures.

SUBSTANCE: principle applies to construction, in particular to production of face tiles and blocks and can be used in the preparation of wall blocks with face tiles from natural rock, or wood panels and also ceramic tiles. The technical result is to ensure the functional capability of blocks during cost reduction of its preparation. Firstly, flat decorative elements (FDE) are prepared, which can be done in the form of one or more tiles of natural rock or in the form of one or more wood panels, and also a combination of these. FDE may consists of number of fragments of each, and side surfaces of FDE are preliminary polished and are fitted one to the other and then placed in the frame, tightly tuck together and inundated with a liquid building mixture. One or more ready FDE is placed in a shaped tray and concrete is poured and the tray is put on a vibration press and vibrated to complete compaction of the concrete and then the ready block is dried under natural conditions. A formwork for a ready construction block is then prepared. Construction blocks can also be prepared from foam concrete, in which the foam concrete layer is placed in a vertical plane from the internal side of the block. In this case the foam concrete layers are made in the form of separate inserts or layer of foam concrete is made by pouring foam concrete into a tray frame using parting metallic plate, which is removed after the tray has been filled up by concrete and foam concrete. For the preparation of flat decorative elements, a moulding box with clamps is used. For the strengthening of the attachment of flat decorative elements to the surface of the construction block, a number of ways are used to preliminary work on rear surfaces of the flat decorative elements. To widen the nomenclature of construction blocks, blocks can be made in form of half-blocks, corner blocks or double sided polished blocks. For work convenience, blocks are prepared with an opening at the top with an undercut for proper handling and hand grip.

EFFECT: ensuring functional capability of a block and reduction of its production cost.
