LONG-LENGTH LENGTHWISE STRUCTURE WITH BUTT JOINT SECTIONS (VARIANTS) Russian patent published in 2016 - IPC B60P7/06 B60P3/22 E04C3/04 

FIELD: technological processes; metallurgy.

SUBSTANCE: present invention relates to long-length metal structures. Long-length lengthwise sectional structure consists of two longitudinal elements each having at least one pair of mating sections that are joined with appropriate sections of an adjacent longitudinal element by means of a holder. Holder consists of a set of links, including one pair of internal mounting links that when connected form an assembly joint, two external heavy-duty connections (8), two adjustable cores (12) and a pair of thrust inserts (13). Between the assembly joint and external heavy-duty connections (8) there are longitudinal cavities each of which has the ends of the pair of the mated sections separated by a spacer thrust plate that is installed on the vertical plates of a corresponding internal mounting link and/or external heavy-duty connection (8). Lateral sides of the spacer thrust plate are the support for the adjoining edges of the ends which is the continuation of the vertical element of the mated section. Second variant of the long-length lengthwise sectional structure comprises more than two longitudinal elements and the holder has more than one pair of internal links, that when connected form an assembly joint each.

EFFECT: invention improves the performance characteristics of long-length lengthwise sectional structures.
