Embodiment 2
[0067] Embodiment two Figure 12 and Figure 13 It is a partial structural schematic diagram of an embodiment of the multi-cavity concrete-filled steel tube column connection structure from different perspectives; Figure 14 and Figure 15 It is a partial structural diagram of another embodiment of the multi-cavity concrete-filled steel tube column connection structure from different perspectives; since the connection methods between the multi-cavity steel tube concrete columns and steel beams are basically the same, for the sake of simplicity and clarity, only the part of the connection structure is shown in the diagram Schematic structure. see Figure 12 and Figure 13 As shown, the multi-cavity concrete-filled steel tube column connection structure provided by the embodiment of the present invention includes the connection structure between the first multi-cavity steel tube concrete column and the H-shaped steel beam, and the first multi-cavity steel tube concrete colum...

The invention discloses a multi-cavity steel pipe concrete column and a connecting structure thereof, and relates to the technical field of civil engineering. The concrete column comprises a multi-cavity steel pipe, the multi-cavity steel pipe is formed by connecting a rectangular steel pipe and U-shaped steel, concrete is poured into a plurality of cavities of the multi-cavity steel pipe, and the section of the multi-cavity steel pipe is a special-shaped section and comprises one or more of a T shape, a cross shape, an L shape and a linear shape. The connecting structure between the multi-cavity steel pipe concrete columns is formed by end areas of the multi-cavity steel pipe, horizontal connecting plates and vertical connecting plates. The connecting structure of the multi-cavity steel pipe concrete column and a beam is formed by connecting the multi-cavity steel pipe, a beam end area, an H-shaped steel connecting piece, a steel plate and the like. The concrete column and the connecting structure thereof are simple in construction, the problem that building beam columns are exposed indoors can be solved, and mechanical properties such as the bearing capacity and the like of a building structure cannot be affected.
Description
technical field [0001] The invention relates to the technical field of civil engineering, in particular to a multi-cavity steel pipe concrete column and its connection structure. Background technique [0002] With the development of prefabricated buildings, more and more multi-high-rise residential buildings adopt steel-concrete composite structures. Commonly used steel-concrete composite structures mainly include frame structure, frame-shear wall structure and shear wall structure. The columns in the frame structure often adopt rectangular steel tube concrete columns, etc., due to the need to take into account the requirements of the structural earthquake resistance and other bearing capacity, the cross-section of the columns is often relatively large, and the indoor beams and columns will be exposed after decoration, which will affect the headroom of the room; If the cross-section of the column is designed to be smaller, the bearing capacity and other performances of the ...
