METHOD TO MANUFACTURE LAMINATED CONSTRUCTION BARS FROM WOOD AND CONSTRUCTION ARTICLES FROM THEM Russian patent published in 2011 - IPC E04C3/12 

FIELD: construction.

SUBSTANCE: invention relates to construction, and namely to methods for manufacturing of wooden laminated bars. Method for manufacturing of laminated wooden bars consists in assembly of multilayer pack from thickness-calibrated dried boards in each layer, at the side of wide faces of which there are stepwise-displaced longitudinally-aligned compensatory slots-grooves, in application of glue compound onto wide faces of boards in process of pack assembly, in pressing of boards pack to polymerise glue, in mechanical treatment of pack glued after polymerisation with formation of construction bar. When forming inner layers of pack, boards with various widths of faces are used, being joined to each other in forming layer of pack along side edges, and/or unedged boards are used, which are previously sawn longitudinally and joined to each other along unedged faces in forming layer of pack. Joined zones of boards are filled with glue compound, and zones of connection of according boards in each subsequent layer are displaced relative to zone of boards connection in previous layer of pack, or zone of boards connection in forming layer of pack are covered with boards calibrated along width of forming pack.

EFFECT: expansion of method functional capabilities.
