Rozměrová stabilita a borcení konstrukčního masivního a lepeného dřeva z buku
Pecháčková, Pavlína
The aim of the thesis is to compare swelling and collapsing of structural massive and laminated wood of beech. Prisms of size 10x10x1000 mm are for 30 days submerged in water. Thereafter the experimental values of swelling are settled and also are settled the coefficients of swelling and transverse and longitudinal collapsing. The repercussions of beech wood by solid prisms and effect of glue and individual plates with glued blocks are analysed. In our experiment, the values are larger volumetric swelling in solid wood and in tangential, radial and longitudinal swelling the opposite is true. Cross warping achieves higher values for laminated prisms and longitudinal collapsing has been measured only in solid samples.
