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 Dmax 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. ^ 2 dwg |
