[0037] Specifically, the concrete steel beam 1 includes a first concrete encapsulation layer 101, a steel beam 102 and a first stiffening component 103. The steel beam 102 is arranged in the first concrete encapsulation layer 101, and at least one end of the steel beam 102 extends out of the first concrete encapsulation layer 101.

The concrete steel column 2 includes a second concrete encapsulation layer 201, a steel column 202 and a second stiffening assembly 203. The steel column 202 is arranged in the second concrete encapsulation layer 201. At least one end of the steel column 202 extends out of the second concrete encapsulation layer 201. The end of the steel column 202 extending out of the second concrete encapsulation layer 201 has a second connection part 204. The second stiffening assembly 203 is arranged in the second concrete encapsulation layer 201. The second stiffening assembly 203 is located on the circumferential side of the steel column 202. The side wall of the concrete steel column 2 is provided with a third connection part 205 fixedly connected to the first connection part 104.

[0038] In this embodiment, the first concrete encapsulation layer 101 encloses the steel beam 102 and the first stiffening assembly 103. The first stiffening assembly 103 is arranged on the peripheral side of the steel beam 102. At least one end of the steel beam 102 extends out of the first concrete encapsulation layer 101. The end of the steel beam 102 extending out of the first concrete encapsulation layer 101 has a first connecting portion 104.

During transportation or lifting, the first stiffening component 103 and the second stiffening component 203 can divide the corresponding stress to prevent the stress from being concentrated at one point, causing cracks in the concrete steel beam 1 and the concrete steel column 2, and causing them to be unusable, which is conducive to improving the construction progress.

[0041] In one embodiment, the first reinforcing component 103 includes a plurality of transverse steel bars 1031 and a plurality of first stirrups 1032 arranged on both sides of the steel beam 102, adjacent transverse steel bars 1031 are arranged at intervals, and the plurality of first stirrups 1032 are arranged at intervals along the extension direction of the transverse steel bars 1031, one end of the first stirrup 1032 is fixedly connected to the bottom surface of the upper flange plate of the steel beam 102, and the plurality of transverse steel bars 1031 are fixedly connected to the first stirrups 1032 respectively.

The six transverse steel bars 1031 are respectively fixedly connected to the first stirrups 1032. Multiple first stirrups 1032 are arranged at intervals along the extension direction of the transverse steel bars 1031 to achieve multi-point fixation of the transverse steel bars 1031. The upper ends of the first stirrups 1032 are fixedly connected to the bottom surface of the upper flange plate. The first stirrups 1032 and the transverse steel bars 1031 can effectively improve the strength of the concrete steel beam 1. The number of first stirrups 1032 can be determined according to the required process and the length of the transverse steel bars 1031, and is not specifically limited here. Preferably, the six transverse steel bars 1031 are respectively fixed to the first stirrups 1032 by binding with thin steel wires, and the six transverse steel bars 1031 can also be respectively fixed to the first stirrups 1032 by welding.

[0043] In other embodiments, the first reinforcing assembly 103 may include four, eight, or other numbers of transverse steel bars 1031 .

[0045] In this embodiment, if Figure 1 and Figure 2 As shown, the top surface of the upper flange of the steel beam 102 and the top surface of the first concrete envelop 101 are coplanar, with the top surface of the upper flange of the steel beam 102 exposed from the first concrete envelop 101. Multiple studs 3 are provided on the top surface of the upper flange and the bottom surface of the lower flange of the steel beam 102.

[0052] In this embodiment, if Figure 4 As shown, the second reinforcement assembly 203 includes sixteen longitudinal steel bars 2031, which are respectively positioned around the steel column 202. The longitudinal steel bars 2031 on opposite sides of the steel column 202 are arranged one by one opposite each other.
