Embodiment Construction

[0049] In order to solve the problems of small internal space of special-shaped steel columns in the technical field of construction engineering, complicated horizontal cross-section structure, cumbersome manufacturing of factory components, too many welding seams in construction and installation, heavy workload of on-site welding, high steel consumption indicators, and high building construction costs, etc. Problem, the inventor considers that the design is applicable to the column building profiles of middle and high-rise buildings.

[0050] The inventors of the present invention found that filling concrete into circular or rectangular steel pipes, the formed steel pipe concrete columns have many advantages such as simple construction, convenient industrial production, reusable steel materials, energy saving and environmental protection, and are suitable for prefabricated steel structure buildings construction.

[0051] However, the section size of this single traditional re...

Abstract

The invention relates to a steel reinforced concrete core tube and rectangular concrete filled steel tube special-shaped column structural system. The structural system comprises a steel reinforced concrete core tube, a plurality of rectangular concrete filled steel tube special-shaped columns, a plurality of groups of steel beams through which the steel reinforced concrete core tube and the rectangular concrete filled steel tube special-shaped columns are connected and steel beams connected between the rectangular concrete filled steel tube special-shaped columns. The structural system also draws double guarantees of vertical load and horizontal lateral stiffness of a high-rise building into consideration; on the one hand, the lateral stiffness of the steel reinforced concrete core tube is extremely strong, so that most horizontal load of the building can be borne, and on the other hand, the rectangular concrete filled steel tube special-shaped columns mainly bear the vertical load; and steel is saved, and the project cost is lowered.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular, the invention relates to a structural system of a rigid concrete core tube and a rectangular steel tube concrete special-shaped column. Background technique [0002] With the continuous improvement of the level of urbanization, the population density of cities represented by the Beijing-Tianjin-Hebei, Yangtze River Delta, Pearl River Delta urban agglomerations and cities with a permanent population of more than 3 million has gradually increased, resulting in the continuous emergence of a large number of high-rise buildings. To this end, the State Council issued the "Opinions on Promoting the Sustainable and Healthy Development of the Construction Industry", and determined the goal of "making prefabricated buildings account for 30% of new buildings in about 10 years". [0003] At present, the construction industry is gradually vigorously developing and promoting pre...
