Connecting node for steel pipe constrained steel recycled concrete column and steel beam and construction method thereof

Abstract

The invention relates to a connecting node for a steel pipe constrained steel recycled concrete column and a steel beam and a construction method thereof. The connecting node comprises the steel pipe constrained steel recycled concrete column, the steel beam, a sleeve clamping pipe and angle steel, wherein a node area is formed at the intersection of the steel pipe constrained steel recycled concrete column and the steel beam, the steel beam is in fastened connection with the angle steel, the steel pipe constrained steel recycled concrete column is fixedly connected with the angle steel through a second high-strength bolt penetrating the concrete column, the sleeve clamping pipe is tightly hooped outside the steel pipe constrained steel recycled concrete column at the node area in a surrounding mode, and two ends of the sleeve clamping pipe are in fastened connection with the steel beam. The constraint effect on recycled concrete of a steel pipe is reinforced by the sleeve clamping pipe, the stress and anti-seismic properties of the node are improved, the steel pipe column is cast with the recycled concrete, and energy saving, environmental protection and stainable resource utilization are promoted.

Description

technical field [0001] The invention relates to the technical field of innovative utilization of steel pipe recycled concrete column node connection, in particular to the steel pipe-constrained steel recycled concrete column and steel beam connection node and a construction method thereof. Background technique [0002] Energy saving and environmental protection are a trend in the development of building structures. Recycled concrete is a green building material that is reprocessed from waste concrete. It has the green and environmental protection advantages of resource recycling, but relatively speaking, it has material defects. Steel pipe confined recycled concrete not only has good mechanical properties of composite structure, but also makes up for the lack of performance of recycled concrete materials, and gives full play to the advantages of resource recycling. [0003] Since its inception, CFST has been more and more widely used in engineering construction due to its su...

Problems solved by technology

At present, a lot of results have been obtained in the research on ordinary CFST beam-column joints, but the joint forms are still relatively small, the quantitative research and analysis are not sufficient, and the joint forms suggested by the code are still difficult to achieve coordination in terms of performance, construction and cost. Of course, it cannot be simply transplanted into the steel tube recycled concrete structure
