Semi-circular formed hollowed section

FIELD: construction.

SUBSTANCE: proposed invention relates to construction and can be used as rod elements at development of bearing structures of buildings and structures of various purposes. In a particular case, these can be rod elements of trusses belts of run-through and non-sprinkling coatings. Said technical result is achieved by the fact that in a curved section of a closed cross-section, a round outline with a shape of workpiece bent edges docked together along the entire length, section has the shape of a semicircle, the height (radius) of which is 1.1766 times larger than the filament size.

EFFECT: technical result of the proposed solution is equal stability (equistability) of the formed hollowed sections from the plane and in the plane of the load-bearing construction, an increase in the bearing capacity, a reduction in the construction height.

SUBSTANCE: invention pertains to construction, in particular to constructions of netted thermo profiles with C or U-shaped section, used as bearing frame elements of pre - fabricated buildings, roofs, fronts, balcony walls, where it is necessary to eliminate "cold joints" effect, and to the method of manufacture of netted thermo profiles. Set task is solved through consecutive vertical drawing of slots made in the central part of the blank symmetrical to the profiling axis from utter rows of the blank to the center in drawing cages forming a netted construction, and further in smoothing cages netted construction is displaced from the center to the edges by smoothing rollers with simultaneous leveling of the netted surface, whereat cells in internal rows of the netted construction acquire diamond shape, and lateral - triangle shape with rounded top, thereat excess of longitudinal draw of the metal on the bridges between the through cells are eliminated by knurling in the shape of buckles in the extension zone.

EFFECT: creation of netted thermo profile having smaller width of the initial blanks (strip) to save up material, retaining geometric characteristics and heat conduction of thermo profiles of identical cross section.

SUBSTANCE: method for thermoprofile production involves strip feed to profile bending mill, sequential transit-wise element overcast by profile-bending mill rollers, perforation of slit row with deflanging in apron form, in checkered order on profile wall. Before feeding to profile-bending mill strip is unrolled from roll and shifted to form compensation loop. After perforation of slit row the profile surface is evened in leveling unit with further profile cutting at given length. Transfer line of cold shaping for thermoprofile production includes profile-bending mill with instrumental adjustments, device for perforation of checkered pattern of slits deflanged in apron form in wall of continuously moving profile. Unrolling and receiving units are positioned in series before profile-bending mill, and after slit perforation device a cutter is positioned. Slit perforation device features leveling unit.
