FORM FOR ELONGATED BUILDING STRUCTURE PRODUCTION OF REINFORCED HARDENING MATERIAL, ELONGATED BUILDING STRUCTURE AND LARGE-SPAN BEAM PRODUCED WITH THE USE OF THE FORM Russian patent published in 2008 - IPC E04G13/02 E04C3/00 

FIELD: construction, particularly forms for building structure production, namely girders, beams, columns used for residential, public and office building erection, repair and reconstruction, created of reinforced hardening material, preferably of reinforced concrete, as well for paving, covering beam, pile, pile columns, post, telecommunicational and/or power supply and/or lighting line poles and structures, networks, bridge and overpass piers and so on creation.

SUBSTANCE: form comprises at least one conduit molding cavity to simultaneously produce several structures. The molding cavity comprises molding surfaces and gutter. The gutter has units for shaping form surface creation member fixation, which are spaced apart along longitudinal gutter axis and the second form member fixation and opening units extending along longitudinal gutter edges, wherein the second members define other shaping surfaces of the form. Two types of form member fixation and opening units are included. Form member fixation and opening units of the first type provide form stripping with form side reciprocation and rotation and form retention in working position. Form member fixation and opening units of the second type provide form side fixation in working position and form side rotation and reciprocation. Each form member fixation and opening unit includes independent holder having the first end movably inserted in paired transversal stiffening members secured to gutter and made as guiding means with orifices.

EFFECT: decreased labor inputs and material consumption, provision of all-weather building structure production, particularly in severe climatic territories characterized by low negative winter temperatures, decreased production time, increased reliability, technological characteristics and quality of ready building structure, possibility to produce several articles having different standard dimensions, including elongated ones, in single device.
