Embodiment Construction

[0038] The specific embodiments of the present invention will be described below in conjunction with the accompanying drawings. For the convenience of description, the orientations such as up, down, left, and right in the views are directly used in the following detailed description process, and are used to indicate the positions of the various components in the figure. This orientation description is not limiting.

[0039] like Figure 2A As shown, the present invention provides a preferred column 100 comprising four corner steel tubes 21, each corner steel tube 21 being preferably a rectangular steel tube, and most preferably a square steel tube. Side plates, preferably corrugated side plates 3 , are arranged between adjacent corner steel pipes 21 . For the corner steel pipe 21 and the corrugated side plate, various connection methods can be used, such as welding. The setting of the wave height and wave spacing of the corrugated side plate 3 can be selected according to th...

Abstract

The present invention proposes a column, which includes four corner steel pipes, and side plates are arranged between adjacent corner steel pipes. It is characterized in that an intermediate tie structure is arranged on the adjacent corner steel pipes. The structure is used to connect the second beam lower flange of the outer second beam. Preferably, the intermediate tie structure includes: a first vertical tie plate, a second vertical tie plate and a middle outer partition arranged on the adjacent corner steel pipes, and the two ends of the middle outer divider The first vertical tie plate and the second vertical tie plate are respectively connected. In addition, the invention also provides a connection method between a column and a beam. The feature of the present invention is that it can effectively transfer the horizontal force of the second external beam to the other side of the column through the beam-column node, which helps to balance the horizontal force of the external beam on both sides of the column and effectively reduces the internal force. The number of partitions should be adjusted to avoid too close spacing of internal partitions, which will affect the compactness of concrete pouring in the column.

Description

technical field [0001] The invention relates to a column in the technical field of construction and a method for connecting it to an external beam, in particular to a column using corner steel pipes. Background technique [0002] The traditional structural columns are concrete frame columns or concrete filled steel tube columns, among which concrete is the most common filling material. For concrete frame columns, a large number of scaffolding projects are set up on the construction site as formwork systems, and each formwork structure is formed independently and only works during the concrete pouring stage, resulting in a lot of waste of manpower and material resources; CFST columns, "Technical Specifications for Concrete-filled Steel Tube Structures" ", "Code for Design of Steel Structures" and other national standards and regulations put forward relatively high requirements for the steel pipe part of the CFST technology. In view of the restrictions of these codes, if the ...
