Profiled clamp
A profiled clamp with at least one profiled segment which extend successively in the circumferential direction of the clamp and are clamped by means of at least one clamping device. The profiled segments have a profile which in cross-section is essentially inversely trough-shaped or cup-shaped. When the clamp is clamped, flanges which are provided at the ends of two pipes to be connected by the clamp are pressed toward each other between diverging side walls of the profiled segments. Gaps with a bottom each are provided between adjacent profiled segments. In each gap is provided a resilient metal strip at a distance from the bottom of the gap which is greater than the thickness of the bottom of the profiled segments, wherein the metal strip extends transversely of the plane of the clamp, and wherein the metal strip is mounted through lateral arms of the metal strip at the bottom of the gap.
1. A profile clamp comprising profiled segments extending successively in a circumferential direction of the clamp and clampable by at least one clamping device, wherein the profiled segments have an essentially inverse trough-shaped profile,
wherein the profiled segments each have diverging side walls for receiving therebetween flanges with equal diameters provided on ends of pipes to be connected by the clamp,
wherein the flanges are pressed toward each other by the side walls when the clamp is clamped, wherein gaps having a bottom each are provided between adjacent profiled segments,
further comprising resilient metal strips mounted in each gap,
wherein, in an untensioned state of the clamp, each metal strip has a straight middle portion which has a distance from the bottom of the gap which is greater than two times the thickness of the bottom of the profiled segments,
wherein the metal strip extends transversely of the plane of the clamp and is loosely fastened through lateral arms of the metal strip at the bottom of the gap,
wherein the profiled segments are attached to the inner side of a flexible clamp strip,
wherein the lateral arms end radially outside of the clamp strip and the straight middle portion is located radially inwardly of the clamp strip, and wherein the straight middle portion is bent outwardly in the tensioned state of the profiled clamp.
2. The profile clamp according to claim 1 , wherein the arms diverge toward one of the edges of the bottom of the respective gap, and wherein the arms loosely extend around the edge.
3. The profile clamp according to claim 1 , wherein, in the untensioned state of the clamp, the distance is greater than twice the thickness of the bottom of the profiled segments and smaller than a radial length of the sidewalls of the profiled segments.
4. The profile clamp according to claim 1 , wherein the gaps are arranged at essentially equal circumferential spacings.
5. The profile clamp according to claim 1 , wherein three gaps are provided.
6. The profile clamp according to claim 1 , wherein the profiled segments are attached to the inner side of the flexible clamp strip which can be clamped by the clamping closure, wherein the clamp strip forms the bottom of the gaps.
