Known wooden beehive frames with thinned upper and lower bars. Due to the thinning of the bars is achieved an increase in the useful volume of frames to contain additional honey bees and a decrease in copper-free space, which has to overcome during wintering bees at the transition from the socket body upwardly into the stern. To save stiffness thinned rails on a bend has to be equipped with their ribs. In the utility model, the proposed VN Shevchenko, patent RU №110227 U1 20.11.2011 additional ribs are formed of wood and the bars become T-shaped profile. However, the ribs still not enough. Therefore, to prevent bending when pulling bars attenuated honeycombs reinforcing wire between the upper and lower bars, with ribs in the middle of the frame bar-put tensioner that prevents bending bars.Another embodiment stiffeners - a metal plate, which is glued to a middle plane of a thinned block of wood is cut along this plane. The protruding beyond the upper and lower metal plates bar strips nasverleny openings through which passed and stretched honeycombs reinforcing wire. Bonded metal plate provides rigidity for bending bars, however, to improve zheskosti most frame used further angular fixing elements (AN Vereshchagin, utility model patent RU №11004, appl. 04.02.1999, publ. 16.09.1999).The proposed technical solution - used as the upper and lower bars hive frame metal rolling with a T-shaped cross-section or double metal corners allows for an increase in hardness of bars to give both the tensioner and the angular fixing elements, that is to simplify the frame hives.Frame with corners can be equipped with a plastic honeycomb, placing it between the corners and secure the studs. For this purpose it is desirable that the sheet along the contour of honeycombs smooth band was retained, the width of which coincides with the width of parts of the shelves.Finally, the side strips of wood, each can also be replaced by two metal brackets, shelves rivets which join the upper and low
