Four-limb steel column for connection of cellular connection plates

Abstract

The invention discloses a four-limb steel column for connection of cellular connection plates. The four-limb steel column for connection of cellular connection plates 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 and a steel connection plate IV, wherein the steel tube limb I, the steel tube limb II, the steel tube limb III and the 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 connection plate I, the steel connection plate II, the steel connection plate III and the steel connection plate IV are cellular connection plates, the middles of which are provided with holes; 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. The four-limb steel column for connection of cellular connection plates is capable of improving the stress property of the latticed columns and improving the rigidity and the buckling strength of the steel columns in a relatively economic manner.

Description

technical field [0001] The invention relates to the technical field of a novel building structure, in particular to a limb steel column connected by a honeycomb connecting plate. Background technique [0002] Compared with traditional concrete structures, steel structures have the advantages of light weight, short construction period, and good seismic performance, and are more and more favored by people, thus being 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 multi-high-rise buildings, long-span structures, and heavy-duty factory buildings, when the number of building floors gradually increases and the upper load increases, it will inevitably lead to an increase in the cross-sectional size of the steel column, thereby incr...

AI Technical Summary

Problems solved by technology

However, the cross-section of the lattice steel column is composed of single limbs connected by embroidered materials. The fabrication and construction are relatively cumbersome, the workload of the connection is too large, and the shear deformation of the imaginary axis is relatively large, which will cause certain additional deflection. It will reduce its working performance; especially the difference between the stability of the virtual and real shafts is large, resulting in the inability of its materials to be fully utilized, and it will inevitably increase the overall cost of the project; moreover, when there is a large horizontal concentration somewhere in the column When the force acts, in order to avoid the bending of the column limb, it is necessary to set a diaphragm at this place, which will increase the steel consumption and construction difficulty, reduce the construction speed, and increase the construction period, thereby further increasing the overall cost of the project
