FIELD: construction. ^ SUBSTANCE: invention relates to the field of construction and may be used in particular as frame support in fixation of curb elements at the bottom, and also for other works inside and outside premises, which are executed at relatively significant height. Curb support comprises frame produced by serial connection of lower end frame, side frames and upper end frame, every of which has units of connection with upper and/or lower frames and is arranged of tubular elements arranged at the right angle to each other, side frames arranged with identical width and two linear dimensions that very in height, are installed pairwise in tiers over each other with alternation of side frames of one size and side frames of another size, at the same time each tier of support is formed with two side frames installed in parallel vertical planes along parallel sides of end frames, side frames of further tier are also installed in parallel vertical planes, and each of frames is installed at the angle of 90 to underlying frame, at the same time support is equipped with at least one diagona, having middle tubular part, tailpiece with fixtures to transverse crossbar arranged on side frame, and upper part arranged with the possibility of interaction with response element fixed in bracket of side frame, upper part is arranged in the form of grip arranged at the angle of 33-43 to longitudinal axis of middle part, at the same time opening for response element arranged in the form of dropping tab, has four flat faces, the first of which, nearest to place of connection of middle and upper parts, is oriented at the angle of 47-57 to longitudinal axis of middle part, adjacent second and third faces are arranged at the angle of 91 -94 relative to the first face, and opposite fourth face is arranged at the angle of 7-12, besides between the fourth and second face there is a passage for response element, which is arranged in the form of tab hingedly installed in bracket. ^ EFFECT: simplified assembly and disassembly of structure by creation of universal diagonal supporting element (diagonal), providing for stiffness of frame support with provision of device operation reliability increase. ^ 3 cl |
