Fabricated special-shaped column-concrete system

Abstract

A fabricated special-shaped column-concrete system belongs to the technical field of structural engineering. The fabricated special-shaped column-concrete structural system is composed of fabricated special-shaped square tubular columns, fabricated beams and fabricated floors; the fabricated special-shaped square tubular columns are in an L shape, T shape and cross shape and are composed of concrete and section steel according to different positions located in and different sizes; the fabricated beams are in a same shape, and are convenient to process and construct; and the fabricated floors are connected with the beams through pins, and the connection between all structures is achieved through welding and grouting. According to the fabricated special-shaped column-concrete system, a steel structural system combines the concrete with the steel structure, defects of the concrete structure are overcome by taking use of the steel structure, defects of the steel structure are overcome by taking use of the concrete structure, and loading capacity and service life of the structure are improved simultaneously. In addition, modularization, industrialization and fabrication are integrated, therefore the construction speed is accelerated, the engineering cost is reduced, and the modernization of buildings is achieved.

Description

technical field [0001] The invention designs an assembled special-shaped column-concrete system, which belongs to the technical field of structural engineering. Background technique [0002] my country's annual urban and rural housing area is 2 billion square meters, of which more than 80% are high-energy buildings, and the energy consumption per unit building area in my country is more than twice that of developed countries. According to the statistics of the China Iron and Steel Association, my country's steel output exceeded 700 million tons in 2011, ranking first in the world's steel output for 16 consecutive years. The steel structure building area in developed countries accounts for more than 50% of the total building area, and Japan accounts for 80%. The degree of domestic construction industry is less than 10%. As the country with the largest construction scale and steel output in the world, China lags behind seriously in the development of housing steel structures. ...

Problems solved by technology

[0003] The combined structure of steel and concrete has been developed so far, and great achievements have been made, but most of them are based on concrete and supplemented by steel, and the characteristics of steel structures have not been fully utilized.

At present, the huge problems of steel structure buildings are easy to rust and not fire-resistant, while the problems of concrete are poor bearing capacity and poor ductility
