BAR-LIFTING PANEL Russian patent published in 2019 - IPC E04B5/02 

FIELD: construction.

SUBSTANCE: invention relates to building elements of buildings and structures. Bar-lifting panel is made of light and strong material, comprises panel body, two covers installed in guides on upper end surface of panel with possibility of movement by means of screw mechanism, four supports located on lower surface of panel. Panel body is made in the form of box of rectangular shape, open from above, with holes of tetrahedral section, arranged in one row from right and left lateral sides. Each hole on the right side of the box is aligned with the corresponding opening on the left side, the number of which is identical on each side. Bar-lifting elements are installed inside barrel and fixed vertically, each of which is made in the form of rectangular tetrahedral bar contacting with next standing bar-lifting elements identical in design. Each of them has in its lower part a transversal through four-sided channel, and in the middle part – a vertical channel of rectangular cross-section opening to the upper surface. In lower part vertical channel is pneumatically and perpendicularly connected with transverse through channel. Inside the vertical channel there are two longitudinal bars in the form of rectangular triangles, one on one side, and other below the first on the opposite side, with their small legs with their small legs facing the transverse through channel, hypotenuse of each of them is located at an angle to the longitudinal axial line of the vertical channel, is parallel and equal in length to the opposite section of the wall of the vertical channel. In the lower part of the vertical channel, at the point of its connection with the transverse through channel, two rectangular longitudinal bars of identical size are attached on opposite side walls, the distance between which corresponds to the width of the inlet opening on the upper end surface of the bar-lifting element, the lower surface of which is smooth. Distance between two rectangular bars is also equal to sum of two small legs of rectangular triangles. All transverse through channels of each bar transient barrel row are interconnected, and extreme ones are connected to corresponding tetrahedral holes on side surfaces of box, number of which is equal to number of cross rows of bar-lifting elements. Flooring is fixed on the upper part of the bar-lifting panel at some distance from the covers.

EFFECT: invention improves operational characteristics and widens field of use of the panel.
