Abstract
Przedmiotem zgłoszenia przedstawionym na rysunku jest sposób wytarzania elementów konstrukcyjnych w jakim jedno-, dwu- lub trzyletnie pręty wierzb krzewiastych gatunku Salix viminalis okorowuje się i usuwa odgałęzienia, korzystnie pręty wierzby zgniata się lub miażdży, a następnie na pręty nanosi się żywicę izocyjanianową PMDI lub inną żywicę, w tym wiążącą na ciepło, zachowując stopień zaklejenia, który wynosi 18% – 20% i umieszcza się pręty w formie tak, aby możliwie ściśle wzajemnie przylegały i prasuje się je przez około 24 godziny przy zachowaniu ciśnienia prasowania 60 MPa w temp. pokojowej ok. 20°C, po czym belkę wyjmuje się z formy.
