METHOD TO MANUFACTURE SUPPORT-BARRIER ELEMENTS OF WALL BEAM FROM UNDERSIZED RAW WOOD Russian patent published in 2014 - IPC B27B1/00 

FIELD: construction.

SUBSTANCE: invention relates to construction and wood working industry, in particular, to the method to manufacture prefabricated support-barrier elements from undersized raw wood. A log is rounded and milled at the outer side in order to give the specified shape to finishing materials with their simultaneous separation by means of sawing. Then on the remaining round-edge cant they mill grooves for heat insulation material, and support-barrier elements of the prefabricated wall beam are separated by means of sawing. At the same time support sites of barrier elements are given different width equal to 1/3 and 2/3 width of the site of the round-edge cant. Then the element having smaller width of the site by means of sawing is divided into two parts of equal height. At the side opposite to the site with the groove closer to the sap side, grooves are made by milling for heat insulation material. Parts of the separated element are installed by their flat sites into sites of an integral element, in the grooves of which there is a cord sealant. Then everything is fixed by screws, besides, all components are installed by their sap surfaces at one side. From the support-barrier element at the sap side by means of sawing they separate a stock for production of finishing material. The support-barrier element is milled.

EFFECT: increased yield of workable wood.
