Bend-resistant prestressed profiled section - has tube fitting between adjustable stops and surface to resist tube bending

摘要

The bend-resistant prestressed profiled section comprises the profiled section proper and a tube fitting between two stops spaced apart along the section in the lengthwise direction. One or both the stops are adjustable, and a supporting surface is provided between tube and profiled section at the central part, to resist bending of the tube. The latter can be accommodated inside a groove formed in the profiled section, while the supporting surface can be formed by a saddle bracket engaging at its ends with the latter.
