Problems solved by technology
In order to meet the requirements of the bearing capacity of the column, the usual practice is to increase the width of the flange of the column, which may cause the flange of the column to protrude from the wall, affecting the usable area of the building and the appearance of the building
[0004] At the same time, some composite columns formed by conventional H-shaped steel members filled with concrete have a single structural shape, which cannot meet the needs of different use occasions

Embodiment Construction
[0030] Please refer to the attached figure 2 To attach Figure 4 Shown, the present invention is a kind of special-shaped partial composite column, and it is made up of several parts such as square steel pipe 1, at least one T-shaped steel 2 and concrete 3.
[0031] Wherein, the T-shaped steel 2 is welded to the outer surface of the square steel pipe 1 , which is formed by welding a web 21 and a wing 22 . The middle part of the wing plate 22 is vertically welded on the web plate 21, and its width is the same as that of the square steel pipe 1, so as to prevent the special-shaped part of the combined column from exposing the wall. The web 22 is vertically welded to the center of the outer surface of the square steel pipe 1 .
[0032] attached figure 2 It is the first embodiment of the special-shaped part combined column of the present invention, and its T-shaped steel 2 is specifically provided with two, which are welded to two adjacent outer surfaces of the square steel p...

The invention relates to a special-shaped partial composite column and a construction method thereof. The special-shaped partial composite column comprises a square steel pipe, at least one T-shaped profile steel and concrete. The T-shaped profile steel is welded to the outer side surface of the square steel pipe and comprises a web plate and a wing plate. The middle of the wing plate is welded tothe web plate perpendicularly. The web plate is welded to the center of the outer side surface of the square steel pipe perpendicularly. The square steel pipe and the position between the wing plateand the square steel pipe are filled with the concrete internally. The concrete is wrapped on the web plate. Compared with a partial composite column formed by filling concrete in a regular H-shaped steel column, the special-shaped partial composite column has high rigidity in the two directions of the strong and weak axes of the plane, and has the advantages of being simple in structure, good infire resistance, convenient to use in different occasions and the like.
Description
【Technical field】 [0001] The invention relates to a building component and a construction method thereof, in particular to a special-shaped partially combined column and a construction method thereof, and belongs to the technical field of prefabricated buildings. 【Background technique】 [0002] The steel-concrete partial composite member is a new type of composite member proposed in Europe in the 1980s. The basic type of its section is to fill the flanges of H-shaped steel members with concrete, (such as figure 1 As shown), this composite member has the advantages of large bearing capacity, high rigidity, and good fire resistance. [0003] The bending stiffness of the part of the composite column formed by the conventional H-shaped steel member filled with concrete is much smaller in the direction of the weak axis than the direction of the strong axis. When this part of the composite column is subjected to axial pressure, it usually loses stability around the weak axis of th...
