LONG-LENGTH STEEL CONCRETE ELEMENT Russian patent published in 2017 - IPC E04C3/293 

FIELD: construction.

SUBSTANCE: element is proposed, including a concrete element (1) covered by a reinforcing ring from rolled sections (2), with openings (5) in flanges, arranged in rows with the same pitch and connecting cross elements, the ring being connected to the concrete element for the joint operation by means of concrete keys (6) located in the openings (5) of the rolled sections. According to the invention, the long-length steel concrete element is made with the possibility to increase the length, changing the shape by length and the position in space, wherein the concrete element and the reinforcing ring elements are connected monolithically, and the openings in the rolled sections are made with the possibility to be filled with concrete, forming simultaneously the concrete element (1) and the keys (6). As rolled sections (2), either corner sections or channels are used, and either reinforcing rods or plates are used as connecting cross elements.

EFFECT: expanding the area of using the steel concrete element as long-length bearing and non-bearing elements, reducing the labour consumption of manufacture due to the possibility of monolithically forming the long-length steel concrete element.
