Inner-ring type steel pipe regeneration block concrete assembly structure

Abstract

The invention discloses an inner-ring type steel pipe regeneration block concrete assembly structure. The concrete assembly structure comprises a main steel pipe, a reinforced annular plate and the main steel pipe is filled with at least one piece of steel beams, regeneration block and common concrete, the reinforced annular plate is fixedly arranged on the inner side of the main steel pipe, the connection place of the reinforced annular plate and the main steel pipe forms a connection node zone, a node zone steel pipe is arranged in the connection node zone, the node zone steel pipe and the main steel pipe are arranged in a communicating mode, the wall thickness of the node zone steel pipe is larger than the wall thickness of the main steel pipe, the steel beams are connected with the periphery of the main steel pipe and extend outwards along the periphery of the main steel pipe, and the connection place of the steel beams and the main steel pipe is located in the connection node zone. Through the adoption of the inner-ring type steel pipe regeneration block concrete assembly structure, the structural strength of the inner-ring type steel pipe regeneration block concrete assembly structure is guaranteed, and the reutilization of old and dilapidated concrete by means of regeneration blocks can be achieved, so that the effects of environmental protection and energy saving are achieved.

Description

technical field [0001] The invention relates to the technical field of structural engineering in civil engineering, in particular to an assembly structure of recycled block concrete with inner ring steel pipes. Background technique [0002] With the continuous advancement of my country's urbanization process and the implementation of urban renewal plans, a large number of old buildings have been demolished, resulting in a large amount of concrete solid waste, most of which are directly transported to the suburbs for stacking or filling without treatment. buried. [0003] Using the above method, on the one hand, these concrete solid wastes will occupy a large amount of production land, and at the same time cause pollution to the environment, water quality, and soil. [0004] On the other hand, my country's construction industry is developing rapidly, and the consumption of concrete as the main building material is huge, while concrete aggregates need to be obtained by excavat...

AI Technical Summary

Problems solved by technology

The consumption of a large amount of concrete aggregates will inevitably lead to environmental damage and resource consumption, and the cement required to make concrete will emit a large amount of polluting gases and dust during the production process, which will also cause environmental pollution
