Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building structure connectors, and in particular relates to a concrete beam supporting steel column conversion structure node connector. Background Art
[0002] In high-rise steel structure office buildings, the above-ground frame columns are mostly box-section steel columns, and the underground part usually uses reinforced concrete beams. When the box-section steel columns have no conditions to fall in the underground part, a conversion structure of concrete beams supporting steel columns will be formed.
[0003] Since the material of the box-section steel column is steel and the material of the reinforced concrete beam is concrete, steel and concrete are two completely different materials, making it difficult to achieve an effective connection. In engineering, the connection with the upper steel column is generally achieved by setting steel sections in the concrete beam. However, when setting steel sections in the concrete beam, since the shear calculation of the concrete beam requires the setting of stirrups with more than four limbs, the arrangement of the stirrups needs to pass through the flange and web of the steel section. Therefore, it is necessary to open holes in the web of the steel section, which brings difficulties to the construction and reduces the strength of the steel section. Utility Model Content
