<p>The present invention relates to a method for connecting the hollow vertical and horizontal profiles for civil engineering and construction, and to products formed by joining profiles. Multiple slits are made into the direction of the axis or the circumference near an end of the hollow vertical profile and main holes that each accomodate a part of a vertical profile are formed in the horizontal profile at intervals of installation of the vertical profiles The end of a vertical profile is inserted into a main hole, the vertical profile is pressed into the direction of its axis and portions of the vertical profile between the slits, are bent outwardly. The portions bent outwardly extend to the outside of the vertical profile and into the inside of the horizontal profile, and thereby the hollow vertical profile and the horizontal profile are fixed. <IMAGE></p> |
