FIELD: construction.
SUBSTANCE: method of construction beam production out of modified wood involves wood modification by squeezing fine metal powder into lumber cavity, with further formation of lumber face by rolling even surface before feeding it into reverse mold, where lumber is put by metal faces together. Then ultra high frequency (UHF) current is applied to beam ends to mollify metal powder, and modified materials are connected in reverse mold by pressing, at the moment of which UHF current is switched off, and obtained seam is cooled, finished beam is extracted from reverse mold freeing it for next beam pressing.
EFFECT: obtainment of construction beams of specified shape and strength properties.
