SYSTEM OF UNIVERSAL CONSTRUCTION FORMWORK ELEMENTS Russian patent published in 2017 - IPC E04G11/08 

FIELD: construction.

SUBSTANCE: system of universal formwork elements comprises the main power element - a crossbar 1, represented by a dismountable structure consisting of two standard profiles 2 and 3 with perforations 4 serving to reduce the weight of the crossbar 1. The crossbars 1 are made of several dimension-types, while the length of the selected channels 2, 3 is standard and is multiple of the pitch of the perforations 4 in the rolling. In the walls 5 of the crossbars 1 along the symmetry axis, openings in the form of a circle 6 and/or an elongated hexagon 7 are made, serving for mounting fasteners therein, ensuring the connection of the adjacent formwork panels 8, respectively, by means of pins 9 for the circular openings 6 or by means of a wedge 10 for the openings in the form of an elongated hexagon 7. The cross-sectional shape of the wedge 10 is an elongated hexagon and corresponds to the shape of the opening 7.

EFFECT: increasing the efficiency of using the structural elements due to the universality of the elements used.
