T-shaped steel pipe-steel rib recycled concrete combination column

Abstract

The invention relates to a T-shaped steel pipe-steel rib recycled concrete combination column. The T-shaped steel pipe-steel rib recycled concrete combination column is composed of a steel rib, a steel pipe and recycled concrete, wherein the steel rib is formed by welding steel plates; the recycled concrete is located in the steel pipe; the concrete covers the steel rib; the steel pipe is in a T shape surrounding the concrete; the steel rib is welded to form the T shape and is distributed in the T shape; the steel rib which is distributed in the T shape is located at the center of the T-shaped steel pipe and is coaxial to the T-shaped steel pipe; the inner steel rib and the steel pipe are fixedly connected with a bottom plate through welding or bolt connection. The T-shaped steel pipe-steel rib recycled concrete combination column is good for improving the stress performance of a limb part of the T-shaped column; the concrete in the steel pipe is in a three-directional stressing state so that the deformation of the concrete is restricted and the application of fragile and high-strength concrete in the T-shaped column is accelerated; the T-shaped steel pipe-steel rib recycled concrete combination column is a main part of a framework structure in a high-rise and large-span building and has the characteristics of high bearing capability, high rigidity, light weight, good plasticity and toughness, good anti-impact and anti-fatigue performances, excellent anti-seismic property, good durability, energy conservation, environment friendliness and the like.

Description

technical field [0001] The invention relates to a concrete member, in particular to a T-shaped concrete column used in civil engineering, which is a novel T-shaped steel pipe-steel reinforced recycled concrete composite column. Background technique [0002] In the current society, with the development of super high-rise and long-span buildings, ordinary reinforced concrete columns are no longer suitable for heavy-duty columns under large loads. In this case, there are circular steel pipe-steel reinforced concrete composite columns and square steel pipe-steel reinforced concrete composite columns. However, due to people's higher and higher requirements for the building environment, especially the increasing emphasis on the structure of the house and the layout of the living room, the section size of the ordinary steel pipe-steel reinforced concrete heavy-duty column is often larger than the thickness of the wall, which affects the indoor space. It is difficult to meet the re...

Problems solved by technology

However, at present, due to the inherent damage of recycled aggregates and the high water absorption rate caused by the adsorption of a layer of old mortar on its surface, the strength, shrinkage and durability of recycled concrete are poorer than ordinary concrete. The earth limits its scope of use
