Abstract

Predstavljamo zgradbo ter biološke, fizikalne in mehanske lastnosti lesa navadne bukve (Fagus sylvatica L.) v primerjavi z lastnostmi lesa smreke in izbranih listavcev. Fina tekstura, visoka homogenost, nizka anizotropija, srednja do visoka gostota, dobre mehanske lastnosti, dobra strojna obdelava, lepljenje, površinska obdelava ter možnost krivljenja omogočajo široko rabo bukovine. Danes preveč bukovine porabimo za pridobivanje energije, zato bi za njeno boljšo izrabo morali oživiti ali povečati proizvodnjo tradicionalnih in novih polizdelkov kot so žagan les, konstrukcijski in plemeniti furnir, ploščni kompoziti ter izdelki kemične predelave, za energetske potrebe pa bi morali uporabljati predvsem ostanke, ki nastanejo pri predelavi lesa. Glede na predstavljene ugodne lastnosti in uspešno reševanje problema nizke odpornosti bi se lahko usmerili v razvoj inovativnih izdelkov za večjo rabo bukovine v gradbeništvu

Secondary title: Properties of beechwood and its use
Secondary abstract: We present the structure as well as biological, physical and mechanical properties of European beech (Fagus sylvatica L.) wood in comparison with that of Norway spruce and selected hardwoods. Fine grain, high homogeneity, low anisotropy, medium to high density, favourable mechanical properties, machining, bonding, and finishing, as well as suitability for bending, are among the main advantages which enable wide use of beechwood. Large amounts of beechwood are currently used as fuel. However, for its optimal use, we should revitalize and increase the production of traditional and new semi-finished products like sawn timber, structural and decorative veneer, composite boards and products of chemical processing. In contrast, for energy purposes we should mainly use the residues from these wood-working procedures. According to the numerous favourable properties of beechwood and fairly good possibilities of increasing its durability, we should focus on the development of innovative products to increase its use for construction purposes in buildings.
