Junction piece for greenhouse of e.g. agricultural culture, has tube crossing hollow body through two openings facing hollow body and presenting deformation to retain tube along own axial direction of tube on hollow body

摘要

The piece (1) has arches and spacers. A hollow body (2) and a tube (4) are arranged in a crossed manner. The tube crosses the hollow body through two openings (3) facing the body. The tube presents deformation to retain the tube along own axial direction (X) of the tube on the body. The deformation extends in an inner side of the body between the openings. The deformation occupies the form of crushing of the section of the tube. The hollow body is coupled with a section of each arch of a greenhouse. An independent claim is also included for a manufacturing process for a junction piece of a greenhouse.
