Abstract: A connecting element for connecting at least two profile elements, wherein the connecting element is rotatable about an axis of rotation to produce a clamping force, wherein the connecting element has at least one first connecting section and at least one second connecting section, which are each designed to be received in one of the profile elements, wherein the first connecting section has at least one first clamping face, wherein the at least one first clamping face has a predetermined clamping contour, wherein the second connecting section has at least one second clamping face, wherein the first clamping face faces the second connecting section and the second clamping face faces the first connecting section, wherein the first connecting section and the second connecting section are formed such that the profile elements connected by the connecting element extend obliquely relative to each other or crosswise.

Abstract: The invention relates to a connecting element (10) for connecting at least two profile elements (100, 200), wherein the connecting element (10) is rotatable about an axis of rotation (D) to produce a clamping force, wherein the connecting element (10) has at least one first connecting section (12) and at least one second connecting section (14), which are each designed to be received in one of the profile elements (100, 200), wherein the first connecting section (12) has at least one first clamping face (20, 22), wherein the at least one first clamping face (20, 22) is designed with a predetermined clamping contour (KK1), wherein the second connecting section (14) has at least one second clamping face (24, 74), wherein the first clamping face (20, 22) faces the second connecting section (14) and the second clamping face (24, 74) faces the first connecting section (12), wherein the first connecting section (12) and the second connecting section (14) are formed in such a way that the profile elements (100, 200)

Abstract: A fastening of a support rail for a photovoltaic module to a trapezoidal rib of a trapezoidal sheet. The support rail comprises an undercut groove with a groove opening. The trapezoidal rib comprises an upper side and a slanted side. The support rail is positioned transversely to the trapezoidal rib. The fastening includes at least one retaining element comprising a fastening section fastened to the slanted side of the trapezoidal rib, and an engaging extension non-detachably arranged thereon. The engaging extension engages the undercut groove in an engaging position. The engaging extension is insertable through the groove opening into the undercut groove of the support rail in a loose position that is rotated relative to the engaging position. The support rail is held down against the upper side of the trapezoidal rib by the engaging extension. The at least one retaining element is arranged either left or right of the trapezoidal rib.

Abstract: A holder for a profiled rail comprising a holding edge and a for carrier component includes a base body, a clamping element, a screw connection, and a rotary joint. The base body comprises a supporting surface configured to have the profiled rail be placed thereon, a holding-down strip which holds down the holding edge against the supporting surface, and a first opening. The clamping element comprises a second opening. The screw connection passes through the first and second opening and is fixable on the carrier component. The rotary joint comprises an axis of rotation arranged parallel to the supporting surface and to the holding-down strip. The clamping element clamps the profiled rail against the base body with the screw connection. On the base body, the clamping element is guided radially with respect to the axis of rotation between an open and a closed pivot position with the rotary joint.

Abstract: An end clamp for fastening a framed PV module on a carrier profile includes a first and second part with respective tooth systems corresponding to each other. The first and second parts together comprise a first section which holds down a frame of the framed PV module onto a surface of the carrier profile, a second section which laterally fixes the frame, a third section with an opening to have a screw pass therethrough, and a fourth section which supports the end clamp on the surface of the carrier profile. The first and second parts slide one inside the other parallel to the first and second sections in at least one discrete position corresponding to a specific frame height provided between the surface and the first section. The first and second parts thereby have one respective remaining degree of freedom and a clearance fit in two other degrees of freedom.
