Abstract

The invention discloses an assembled rectangular concrete filled steel tubular column-steel girder diaphragm through joint and belongs to the technical field of building structure engineering. The joint comprises a rectangular concrete filled steel tubular column, a plurality of brackets, a plurality of connecting plates, two through diaphragms and a plurality of end plates. Each of the brackets comprises an upper flange, a lower flange and a web. The two through diaphragms include a first diaphragm and a second diaphragm, the first diaphragm and the second diaphragm are respectively connectedwith two ends of the rectangular concrete filled steel tubular column, each through diaphragm is provided with a plurality of extension arms extending to different directions, and the extension arms,along the same direction, of the first diaphragm and the second diaphragm, are connected with the upper flanges and the lower flanges of the corresponding brackets. The wall of the rectangular concrete filled steel tubular column is connected with one end of the corresponding connecting plate, the other end of the connecting plate is connected with the web at one end of the corresponding bracket,and the other end of the bracket is connected with the corresponding end plate. The joint is prefabricated in a factory and is transported to the field so that on-site welding workload is reduced andprocessing precision is guaranteed.

Description

technical field [0001] The invention relates to the technical field of building structure engineering, in particular to an assembled rectangular steel pipe concrete column-steel beam partition through joint. Background technique [0002] The rectangular concrete-filled steel tube column is conveniently connected to the steel beam, the force of the connection node is clear, the bearing capacity is high, and the reliability is high. The frame system formed by connecting with steel beams has the advantages of flexible layout, simple structure, and easy realization of standardization of components. Therefore, the joints between rectangular square concrete-filled steel tube columns and steel beams have shown good application prospects in high-rise and super high-rise buildings. [0003] my country's "Technical Regulations for Rectangular Concrete-filled Steel Tube Structures" (CECS159:2004) recommends four types of rectangular concrete-filled steel tube column-steel beam connect...
