METHOD FOR ASSEMBLING SMALL ARCHITECTURAL FORMS FROM A SET OF PROFILE ELEMENTS Russian patent published in 2022 - IPC B21D39/00 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction of small architectural forms. A method is proposed for assembling small architectural forms from a set of profile elements made by profiling cold-rolled metals, including those with coatings, consisting of working sheets, each of which contains a facing part and two legs with bends made at an angle of 0 to 90 degrees to the legs, and racks of figured profiles, each of which contains a profile dome, two legs and two bends with folds. The assembly is carried out by pushing each bend of the working web into the corresponding folded lock of the adjacent rack with the formation of a tight collapsible lock connection. In this case, each seam lock is formed by a rack fold, made by bending the edge of each profile bend towards the dome, a bend and a straight section of the rack leg. In addition, the straight sections of the rack legs are made with a length of at least four metal thicknesses, are associated with bends and are made at an angle of 80 to 100 degrees to them, and the height of the seam gap in the seam lock must be at least two metal thicknesses. The width of the limbs of the rack is greater than the width of the limbs of the working web by at least two thicknesses of the metal. Bends of the working web can be made towards the facing part and away from the facing part.

EFFECT: achieving ease of assembly of small architectural forms of various configurations, in saving metal, in reducing labor intensity.
