FIELD: construction.
SUBSTANCE: invention relates to a light slab with an upper cover layer stretching in longitudinal direction (X), with a lower cover layer stretching in parallel to the upper cover layer, distanced from the upper cover layer in direction (Y), perpendicular to the longitudinal direction (X), with a light internal layer stretching between the upper cover layer and the lower cover layer and a crossbar from wood or wooden material stretching between the upper cover layer and the lower cover layer. It is proposed to cut a spiked and/or a slot profile in the crossbar, made as capable of mechanical fixation in longitudinal direction (X) and in direction (Y), perpendicular to the longitudinal direction (X) with the coupled profile of another structural element. Besides, the invention relates to appropriate connection structure and appropriate method of connection structure manufacturing.
EFFECT: simplified manufacturing of a connection structure.
