Profile steel built-in special-shaped steel pipe concrete column structure and manufacturing method thereof

Abstract

The invention provides a profile steel built-in special-shaped steel pipe concrete column structure applied to the field of novel building structures and further relates to a manufacturing method of the profile steel built-in special-shaped steel pipe concrete column structure. Profile steel (3) of each prefabricated column (1) of the profile steel built-in special-shaped steel pipe concrete column structure is arranged in a special-shaped steel pipe (2). A concrete block (5) is arranged between the profile steel (3) and the special-shaped steel pipe (2) and provided with an embedded pipe (6). The profile steel (3) of each prefabricated column (1) is arranged to be of a structure which can be connected with the profile steel (3) of another prefabricated column (1). The outer circles of the special-shaped steel pipes (2) of every two connected prefabricated columns (1) are connected through a closing steel plate (7). The profile steel built-in special-shaped steel pipe concrete column structure has the advantages of being high in bearing capacity, good in ductility, superior in anti-seismic performance, safe and reliable in connection, convenient to construct and the like, and performance of a building is improved.

Description

technical field [0001] The invention belongs to the field of new building structures, and more specifically relates to a built-in section steel special-shaped steel pipe concrete column structure, and the invention also relates to a manufacturing method of a built-in section steel special-shaped steel pipe concrete column structure. Background technique [0002] In the construction industry, traditional prefabricated structures are severely damaged in earthquake disasters. These damages are mainly caused by the weak structure of the connection nodes of the prefabricated structure and unreasonable force, which makes the promotion and application of prefabricated structures in actual engineering limited. some restrictions. However, the prefabricated structure has obvious advantages such as short construction period, easy control of construction quality, and small impact on the environment, and has become an irreplaceable form of architectural structure. Traditional prefabrica...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a simple structure without increasing the cost, which can effectively improve the connection strength between the prefabricated columns and ensure the simple connection and high connection strength of the prefabricated columns, so as to effectively solve the problems of the prior art. In the traditional prefabricated steel concrete and steel tube concrete structures, the column-to-column connection nodes are set at the beam and column joints, resulting in many nodes, complex structures, and difficult construction. The structure has the advantages of high bearing capacity, good ductility, superior seismic performance, safe and reliable connection, convenient construction, simple structure, and good economy. It ultimately improves the performance of the building and ensures the safety of the building.
