FIELD: building, particularly devices for roofing sheet fastening.
SUBSTANCE: fastening device comprises fixed plate installed on roof boarding bar and movable strip. One strip end is bent around fixed plate, another one is folded so that right angle is defined between strip end and fixed strip. The second folded strip end forms vertical section for seamed sheet connection. Fixed plate edges are bent downwards through 90° and snug against roof boarding bar. The fixed plate edges are fastened to the bars and fixed in mounting points. Fixed plate edges are fixed so that a gap is created between fixed plate and roof boarding bar to provide movable strip displacement along fixed plate during sheet fastening operation. Bent plate edges exceed half of roof bearding bar height.
EFFECT: increased reliability of roofing sheet fastening.
