Composite steel pipe concrete column with built-in steel pipe beam tube

Abstract

The invention discloses a composite steel pipe concrete column with a built-in steel pipe beam tube. The composite steel pipe concrete column comprises an outer tube steel pipe, wherein a plurality of inner tube steel pipe concrete columns are arranged in the outer tube steel pipe; each inner tube steel pipe concrete column comprises an inner tube steel pipe; inner tube concrete is filled in the inner tube steel pipe; the inner tube steel pipe concrete columns are connected through connecting lacing elements; a plurality of enhanced bonding ribs are arranged on the inner wall of the outer tube steel pipe; between-pipe concrete is filled between the outer tube concrete pipe and the inner tube concrete columns; The composite steel pipe concrete column with the built-in steel pipe beam tube has the advantages that the carrying force is high; the intensity storage is great; the durability is higher; the cross section dimension and the dead weight of the column component are reduced; the high-intensity materials are sufficiently utilized; the energy sources and the energy sources are saved; the sustainable development requirements are met.

Description

technical field [0001] The invention relates to a composite column, in particular to a composite steel tube concrete column with a built-in steel tube bundle. Background technique [0002] With social progress and economic development, in order to meet the needs of people's life and development, various forms of super high-rise and heavy-duty buildings have emerged, especially the rapid emergence of heavy-duty and super high-rise buildings, which urgently need new technologies and new theories to support development needs of the construction industry. Although the bearing capacity and ductility of ordinary concrete-filled steel tube columns are greatly improved compared with reinforced concrete, the mechanical properties of composite columns are not only reflected in the respective characteristics of the constituent materials, but also match the two materials (steel ratio or hoop index) There is a great relationship. The bearing capacity and ductility of ordinary concrete-...

AI Technical Summary

Problems solved by technology

The bearing capacity and ductility of ordinary concrete-filled steel tube columns are limited by their own size, material properties and processing technology, and cannot meet the needs of over-limit engineering to the greatest extent.
