CANTILEVER OF REINFORCED CONCRETE COLUMN Russian patent published in 2004 - IPC

FIELD: building, particularly eccentric loaded reinforced concrete columns.

SUBSTANCE: column assembly comprises column with upper part of smaller cross-section having embedded sheet members and with lower part of greater cross-section. Upper and lower column parts are connected by area with changing cross-sectional height and ledge edged with sheet member of angle bar is formed between upper and lower parts. Steel removable cantilever is made of rolled I-beam having vertical part connected with I-beam, particularly by welding. Lower I-beam flange rests upon embedded sheet member. Vertical I-beam part are connected with upper column part end. Embedded sheet members extend the distance of 3-4 anchor bolt diameters from column edge. Anchor bolts connect the flange with embedded sheet members. Assembly also has bearing ribs formed under crane girder support. Vertical support reactions D_max are absorbed by upper flange and transmitted to lower embedded sheet member and lower column part through ribs and lower flange.

EFFECT: simplified production process, increased reliability and service life of units connecting crane girders with reinforced concrete columns, simplified structure of formwork used for column manufacturing.
