Steel rib-steel tube glass concrete combined column

Abstract

The invention relates to a concrete component, and in particular relates to a steel rib-steel tube glass concrete combined column in civil engineering. The steel rib-steel tube glass concrete combined column consists of steel tubes, steel ribs and glass concrete, and concrete comprises glass fragments serving as aggregates; the glass concrete comprises coarse glass aggregates with grain diameter of 5-30mm, and fine glass aggregates with grain diameter of 0.1-3mm; according to the volume of each cubic meter of the glass concrete, 300-1,500kg of the coarse aggregate glass, 300-1,500kg of the fine aggregate glass, 400-600kg of the cement and 150-300kg of water are mixed sufficiently; the glass concrete comprises elementary glass, organic glass and inorganic glass. The steel rib-steel tube glass concrete combined column is a main component of a building frame structure in high-rise buildings, and has the characteristics of high bearing capacity, high rigidity, light weight, good plasticity and toughness, good impact and fatigue resistance, excellent earthquake resistance and the like.

Description

technical field [0001] The invention relates to concrete components in the technical field of construction, in particular to a steel frame-steel tube glass concrete composite column used in civil engineering, which is a novel steel tube concrete composite column. Background technique [0002] In "concrete-filled steel tube structure", concrete-filled steel tube columns can be divided into concrete-filled steel tube columns with steel tubes on the outside of the column and concrete-filled steel tube columns with steel tubes inside the column. The former is usually called steel tube concrete column, and the latter is usually called steel tube concrete composite column . Due to the complicated construction of steel tube concrete columns and the need for fireproofing and antirust treatment of steel tubes, steel tube concrete composite columns are mostly used in the construction of high-rise buildings and bridge structures. In composite steel tube concrete columns, the strength ...

AI Technical Summary

Problems solved by technology

3) Since the ductility of concrete-filled steel tube composite columns is mainly provided by longitudinal reinforcement, more longitudinal reinforcement is often required, resulting in difficulties in construction

4) Studies have shown that the inner and outer concrete of this type of column cannot work well together until failure

[0005] Therefore, the research group imagined that it would be a good idea to use waste gas glass as the aggregate of concrete in buildings and form steel-steel-tube glass-concrete composite columns.
