Patent attributes
A tubular structural profile and construction system, produced by cutting and folding a semi-rigid and foldable sheet, having four orthogonal layers joined at fold lines and two internal diagonal layers joining two opposing fold lines. The sheet has six rectangular sections. The cutting lines are positioned for at least one tongue, which coincides with at least one slot located on an opposing fold lines, such that, during the folding, the profile is closed of the coming together of fold lines and both internal diagonal layers, and by means of the insertion of at least one tongue on its corresponding slot, and wherein, in addition, the profile of the formed system can have at least one break in the second external layers and in the two internal diagonal layers, which permit the creation of an engaging area for transverse structural profiles.
