Prefabricated, assembled and integrated type special-shaped column structure and jointing construction method thereof

Abstract

The invention discloses a prefabricated, assembled and integrated type special-shaped column structure and a jointing construction method of the column structure. The prefabricated, assembled and integrated type special-shaped column structure comprises a prefabricated upper column, a prefabricated lower column and a prefabricated laminated beam, wherein the prefabricated upper column and the prefabricated lower column are respectively provided with channel steel in an embedding manner, reserved bolt holes are formed in each channel steel, the adjacent prefabricated upper column and prefabricated lower column are connected through the channel steel by bolts to form an upper and lower through special-shaped column provided with a cast-in-place area, and reinforcing hoops are arranged in the cast-in-place area; the prefabricated laminated beam is anchored in the abnormal column through a longitudinal rib of the prefabricated laminated beam; cast-in-place concrete is injected in the cast-in-place areas of the adjacent two prefabricated upper column and prefabricated lower column and a part, not pouring the concrete, of the prefabricated laminated beam, so as to form a beam and column combined whole body. According to the prefabricated, assembled and integrated type special-shaped column structure and the jointing construction method of the column structure, which are disclosed by the invention, the problems that the vibration of concrete in joint core area of the special-shaped column is not dense and is difficult can be remarkably modified, so that the vibration resistance of joints can be improved; furthermore, the construction speed further can be increased, the construction period is shortened, and the development of building industrialization is facilitated.

Description

technical field [0001] The invention belongs to the field of building structures, and relates to general building structures, in particular to a concrete structure system suitable for industrial production, and in particular to a prefabricated special-shaped column structure. Background technique [0002] At present, with the rapid development of my country's housing industry and economy and the continuous advancement of science and technology, people's requirements for the use of residential buildings are constantly increasing, not only requiring a large usable area, but also requiring a high headroom. High-rise and super high-rise buildings usually adopt structural forms such as frame or frame shear wall. Traditional frame structures or frame shear wall structures usually use rectangular cross-section columns, and the width of rectangular cross-section columns is greater than the thickness of the partition wall between columns. The column corners of the room protrude from ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a prefabricated special-shaped column structure in view of the above-mentioned deficiencies in the prior art. This structure can effectively solve the problem of relatively dense reinforcement in the node area while ensuring the integrity, bearing capacity and seismic performance of the node. Difficult, the problem that the concrete is not compacted by vibration
