METHOD TO MANUFACTURE BSH-BEARING GIRDER FROM BARS AND BSH-BEARING GIRDER FROM BARS Russian patent published in 2013 - IPC E04C3/14 B27M3/00 

FIELD: construction.

SUBSTANCE: method to manufacture a BSH-bearing girder consists in the fact that the following stages are realised in turns: making bars of round timber from boards with preferably lying annual rings, besides, bars accordingly have the first side surface, which is directed to the outer side of the round timber, and the second side surface, which is directed to the core of the round timber, manufacturing of the BSH-bearing girder by means of gluing of several bars in parallel to fibres, which are arranged along their side surfaces, from boards with formation of a layer structure, manufacturing of BSH-bars with the help of sawing of the BSH-bearing girder in parallel to fibres and perpendicularly to the side surfaces of bars, as a result BSH-bars get cutting surfaces, which stretch accordingly perpendicularly to the side surfaces of bars from boards, and adhesion of at least several BSH-bars arranged along their cutting surface with formation of the layer structure.

EFFECT: increased bending strength of a girder perpendicularly to bar plane.
