The Influence of Amount of Layer on the Bending Strenght by Longitudinal Finger-jointing Wood Elements
Abstract Test of bending strength section obtained through longitudinal connecting wooden elements was carried out by an experimental method. The test samples were formed of fir/spruce and using polyurethane adhesive PURBOND HB S609, a total of 243 samples has been formed. Testing the effects of the amount of adhesive on the bending strength of linear coupled sections was carried out on three levels (180, 200, 220) g/m2. This paper attempts to prove assumption that excessive increase in the quantity of adhesive in the adhesive film comes to impairment glued joint strength.
