<p>To create a post for enclosures, partitions, and similar structures consisting of several parts and involving a strip of hollow structural section that will allow the rapid and rational assembly of such enclosures as bar-grid fences and similar structures, whereby disassembly will be impossible without destroying the components, the length (2) of hollow structural section has a gap along one side flanked by two separated flanges (3), which extend either inward or outward and between which are accommodated webs (4) that match the shape of each flange and that are part of a length (5) of more or less T or pi -shaped structural section that closes off the gap, leaving room outside on each side of the flanges between the length of hollow structural section and the matching sections of a spine (6) on a length (5) of T or pi -shaped structural section, whereby the length of T or pi -shaped structural section can be locked into the length of hollow structural section.</p> |
