FORMWORK FOR BEARING COLUMNS Russian patent published in 2025 - IPC E04G13/02 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, namely to the bearing and shaping structural elements of the formwork used in the erection of monolithic buildings and structures for various purposes, namely to the bearing columns formworks. Formwork comprises three sections: lower, middle and upper. Each section consists of parts connected by means of fastening elements to form a rectangle in plane view. Lower flange of lower section in assembled form is horizontal with possibility of installation on mounting surface. Upper flange of lower section is inclined to central vertical axis of future column formwork. Middle section as-assembled is installed between upper and lower sections. Each part of the middle section is made in the form of a horizontally oriented truncated pyramid with a trapezoid in the vertical section, which is installed with its narrow side closer to the central vertical axis of the column formwork. Upper section as-assembled is made similar to design of lower section, installed inverted by 180 degrees symmetrically to lower section relative to horizontal plane between them. Upper flange of the upper section is horizontal with the possibility of supporting beams or floor slabs on it. Upper section lower flange is inclined to central vertical axis of column formwork. All parts of the structure are made of metal.

EFFECT: increased productivity due to the increased strength and rigidity of the formwork, which allows it to act as a load-bearing column during the curing and strength gain of the concrete mixture.
