Cellular connection steel plate-four-limb concrete filled steel tube composite column

Abstract

The invention discloses a cellular connection steel plate-four-limb concrete filled steel tube composite column which comprises a steel tube limb I, a steel tube limb II, a steel tube limb III, a steel tube limb IV, a steel connection plate I, a steel connection plate II, a steel connection plate III, a steel connection plate IV and concrete, wherein the steel tube limb I, the steel tube limb II, the steel tube limb III and steel tube limb IV are connected together through the steel connection plate I, the steel connection plate II, the steel connection plate III and the steel connection plate IV to form a rectangular section column; the steel tube limb I, the steel tube limb II, the steel tube limb III and steel tube limb IV are internally filled with the concrete; the steel connection plate I, the steel connection plate II, the steel connection plate III and the steel connection plate IV are respectively formed by two steel plates which are provided with gaps at the boundary zones and of the same shape; every two steel plates are welded through butt welds to form each cellular connection plate. According to the cellular connection steel plate-four-limb concrete filled steel tube composite column, the materials in two main shaft directions can be fully developed, so that the dosage of the steel is reduced and the comprehensive cost of the projects is lowered.

Description

technical field [0001] The invention relates to the technical field of a novel building structure, in particular to a honeycomb connected steel plate-steel tube concrete composite column. Background technique [0002] With the development of the economy, people's requirements for the structural forms of residential and public buildings are gradually increasing. Compared with traditional concrete, steel structures have the advantages of saving steel, reducing cost, short construction period, and good seismic performance. favored and thus widely used. [0003] Steel columns can be divided into two categories: solid-web type and lattice type according to their cross-sectional forms. Relatively speaking, the solid-web column has a simple structure and is more convenient to connect with other components. However, with the development of public buildings and heavy factory buildings, the increase in the upper load will inevitably lead to an increase in the section size of the ste...

Problems solved by technology

However, in actual engineering, in order not to weaken the shear capacity of the steel column too much, the "expansion ratio" of the steel column section of the honeycomb connection plate will be limited

In this case, especially for the bending column with a large bending moment, its steel limbs may lose their bearing capacity in advance, making it unable to meet the engineering needs
