Abstract
A device for sealed attachment of substantially flat-surfaced cover strips, especially of sheet metal, for single- or double-curve roof surfaces of buildings, with top and bottom clamping members, which can be braced for the side attachment of adjacent cover strips by opposing bolts and which can be attached to a supporting frame. The clamping members have flat clamping surfaces to contact the substantially flat-surfaced cover strips and have clamping bolts that extend through openings on the lengthwise edge of at least one of any two adjacent cover strips. Cover rails are attached to the top clamping members and pass therethrough and are clamped by means of crosspieces which feather out to the side, which on their lengthwise edge carry sealing strips pressed against the outsides of adjacent cover strips. The bottom clamping members each have a crosspiece extending downwardly and having side retaining flanges, by which they are held in a lengthwise slit in profile rods, which run parallel to the cover strips and are attached to the supporting frame.
