JOINING OF STRETCHED WOODEN COMPONENTS Russian patent published in 1997 - IPC

FIELD: manufacture of wooden structures. SUBSTANCE: this can be used in designing and manufacturing of stationary and especially movable sectional load-bearing wooden structures. Joining of stretched wooden components 1 is effected with the help of wooden inserts 2. All joining components are enclosed in metal holder which is made up of two -shaped members 3 interconnected by bolts. In process of joining, zone of joint is laterally compressed which allows due to plastic deformation of material of joining members and created additional frictional forces to increase load-bearing capacity and reliability of joint which is achieved by more reliable contact between joining members and by involvement of metal holder material in work. EFFECT: high efficiency. 4 dwg
