METHOD FOR MANUFACTURING OF GLUED WOODEN STRUCTURES Russian patent published in 2007 - IPC B27M1/02 

FIELD: construction industry, in particular, production of glued wooden structures.

SUBSTANCE: method involves preparing tape for gluing; applying glue onto tape surface with grooves; forming packets and pressing structures; covering outer part of structure base with corrugated film having tensile strength exceeding that of structure base. Film layer has different thickness along span length. Zone of increased thickness of film layer is calculated from formula: L_b=L-2L₁ or L_b=L-2(c+0.5·h), where L_b is zone with increased thickness of film layer; L is length of structure; L₁ is distance from structure end to zone with increased thickness of film; c is length of supporting platform; h is height of structure.

EFFECT: increased longevity and strength of structures used as construction parts.
