HIGH-STRENGTH FIXING DEVICE

construction engineering. SUBSTANCE: device used for joining wood items such as ceilings, bay beams, arches, trusses, frames, and package and made in the form of metal plate with slits has fastening members made in the form of teeth whose edges face different sides. Novelty is that device is provided with anchor teeth installed at diagonally opposite plate corners; anchor teeth have longitudinal bend and notch on edges whose area and length are greater than those of other teeth installed over perimeter of plate and on both sides of transversal neutral axis. Teeth-forming slits arranged over perimeter of plate are made so that their pointed end run from plate corners to its neutral axes on both sides; teeth-forming slits arranged on both sides along transversal axis of plate are made so that their pointed ends are facing each other; longitudinal edges of plate are rounded and bent through 90-180 deg. EFFECT: enhanced stability and strength of longitudinal edges of plate; improved reliability of plate fastening to wood items. 9 dwg
