摘要

The hollow support useful in construction areas, comprises tube-shaped individual hollow profiles (5, 6), which are pushed into one another and fixed together by sliding connection at internal high pressure. The hollow support is flow throughable from medium. The internal single hollow section consists of medium-indifferent material and is contacted with the medium. The hollow support has different cross-sections formed by internal high pressure and contains three single hollow profiles. The outer single hollow profile consists of a material. The hollow support useful in construction areas, comprises tube-shaped individual hollow profiles (5, 6), which are pushed into one another and fixed together by sliding connection at internal high pressure. The hollow support is flow throughable from medium. The internal single hollow section consists of medium-indifferent material and is contacted with the medium. The hollow support has different cross-sections formed by internal high pressure and contains three single hollow profiles. The outer single hollow profile consists of a material, which is resistant oppositely to environmental influences. The hollow support has a curved progression and is a part of carcass structure of a motor vehicle. An independent claim is included for a method for the production of hollow support.
