FORM FOR ELONGATED BUILDING STRUCTURE ERECTION AND COLUMN BUILT WITH THE USE OF THE FORM Russian patent published in 2007 - IPC E04G13/02 E04C3/00 

FIELD: construction, particularly equipment to erect columns for residential, public and office buildings and building structures and to reconstruct or recover said buildings and building structures.

SUBSTANCE: form comprises gutter and sides connected to the gutter to create single conduit system including at least two adjacent elongated molding cavities to simultaneously produce several columns of reinforced hardening material, preferably of reinforced concrete. The column is made as a single member extending along structural member length and having height preferably exceeding one story height. Adjacent molding cavities are separated one from another by common central longitudinal side with two molding surfaces fixedly arranged on gutter. Longitudinal outer sides are of drop type and installed along outer longitudinal edges so that they may reciprocate along gutter width to change working width of each molding cavity in the range from maximal width to minimal width equal to 0.3 of maximal width. The sides may be secured in desired positions, including intermediate position, along gutter width. Gutter rests on discrete supports so that gutter location in vertical direction may be changed and is retained from at least longitudinal displacement in central part. Remainder part thereof may slide in both directions from central part under the action of thermal strain. Form comprises at least two transversal replaceable forming and concrete cutting end diaphragms having different standard sizes corresponding to standard sizes of transversal column cross-sections.

EFFECT: decreased labor inputs and material consumption, possibility to perform works in any weather, mainly in zones with severe climate characterized by low negative winter temperatures, decreased time, increased structural reliability and quality, possibility to produce several columns having different dimensions in single form.
