FIELD: building materials.

SUBSTANCE: invention relates to scaffolding ladder (10). Scaffolding ladder (10) contains two separate side guides (12, 14; 12^(I), 14^(I); 12^(II), 14^(II); 12^(III), 14^(III); 12^(IV), 14^(IV)) and a set of separate elements (16) of ladder steps, which can be attached to side guides (12, 14; 12^(I), 14^(I); 12^(II), 14^(II); 12^(III), 14^(III); 12^(IV), 14^(IV)), retaining devices formed on both side guides (12, 14; 12^(I), 14^(I); 12^(II), 14^(II); 12^(III), 14^(III); 12^(IV), 14^(IV)) for retention of elements (16) of ladder steps, wherein retaining devices are made in the form of grooves (18; 18^(I); 18^(II); 18^(III); 18^(IV)) containing walls (96a, 96b) of the groove for each groove (18; 18^(I)); 18^(II)), or sections (60a, 60b) of the groove wall for each groove (18^(III); 18^(IV)) formed from sections (59a-59d) of the groove on side surfaces (19) of side guides (12, 14; 12^(I), 14^(I); 12^(II), 14^(II); 12^(III), 14^(III); 12^(IV), 14^(IV)), which face each other, and which are made in the form of hollow profiles (43; 43^(I); 43^(II); 43^(III); 43^(IV)), into grooves of which elements (16) of ladder steps are inserted with their free ends (17), wherein free ends (17) of elements of ladder steps rest on wall (96a, 96b) of the groove or sections (60a, 60b) of the groove wall for absorption with side guides of vertical forces arising at joints between elements of ladder steps or ladder steps and side guides, when using the ladder, and dissipation of vertical forces in side guides, wherein at least one protruding rib (44a-44s) is formed, in particular, in the center, or evenly or unevenly spaced ribs (44a-44s) are formed in the longitudinal direction of corresponding side guide (12, 14; 12^(I), 14^(I); 12^(II), 14^(II); 12^(III), 14^(III); 12^(IV), 14^(IV)), which contain(s) specified grooves (18; 18^(I); 18^(II); 18^(III); 18^(IV); 82) or sections (59a-59d) of grooves at least on side surfaces (19) facing each other, in particular on side surfaces (19) facing each other and side surfaces (21) facing away from each other, side guides (12, 14; 12^(I), 14^(I); 12^(II), 14^(II); 12^(III), 14^(III); 12^(IV), 14^(IV)), wherein grooves (18; 18^(I); 18^(II); 18^(III); 18^(IV)) are made in rib (44a-44s) in the form of cutouts, while depths of cutouts or grooves in side guides (12, 14; 12^(I), 14^(I); 12^(II), 14^(II); 12^(III), 14^(III); 12^(IV), 14^(IV)) are limited and either determined by height (49) of the rib of at least one rib (44a-44s), or end at a level of channels (48a-48c) between ribs (44a-44s) of the hollow profile, wherein side guides (12, 14; 12^(I), 14^(I); 12^(II), 14^(II); 12^(III), 14^(III); 12^(IV), 14^(IV)) contain first stops (61) for elements (16) of ladder steps at a level of grooves (18; 18^(I); 18^(II); 18^(III); 18^(IV)). A ladder structure containing such a ladder is also disclosed.

EFFECT: stability.
