FIELD: construction, particularly for manufacturing timber load-bearing structures of bar members.
SUBSTANCE: connection device comprises wooden members to be connected having jointing ends with serrated surfaces, wooden serrated covering plates, releasable metal ring composed of two U-shaped members having orifices for bolt joint and compensating spring and plates. When connection device is mounted with the use of bolt joint transversal compression force is created and maintained by means of compensating springs. Flat springs are installed in bolt joint to provide necessary compression forces in vertical plane.
EFFECT: increased service life.
