FIELD: construction.SUBSTANCE: connection system comprises a cross connector and two C-shaped bars. The connector comprises a transverse face, which at both sides is limited with an appropriate bend rib. From the bend rib approximately at the right angle there is a fastening shelf bent. From the longitudinal edges of the shelves aside at two sides there are hook elements that outgo to grip the bent edge of the lower bar at the bottom. In the transverse face in the area of bend ribs there is one hole, from which a springy tab is stamped. Side hook elements are equipped with a groove, stretching along the entire external diameter of the hook element to its edge. On the top view there is a V-, U- and/or wavy magnified contact surface, preferably a gapless double-point support. The support is created as a result of resting the external edge of the bent bar edge and in the area of the bar edge bending to the hook element. In case of proper integration external edges of the bar rest inside the groove head.EFFECT: possibility of gapless connection, increased rigidity of hook elements, saving of connector material, increased contact surface of hook elements and easier assembly.19 cl, 5 dwg |
