On the one hand, during the installation process, the prefabricated connecting ribs cannot directly penetrate the C-shaped light steel skeleton, and on-site welding of the bypass bifurcated structure is required. On the other hand, during the erection process of the connecting ribs, the structure is relatively thin, and the upper and lower alignment cannot be guaranteed to be neat and consistent. During the stress process, uneven deformation may occur, which will directly affect the bearing capacity and stability of the structure. In addition, the U-shaped steel channel is only welded to the end of the connecting rib through the annular member to achieve the assembly on the side of the foamed concrete, and the overall connectivity is poor, and the U-shaped steel channel is prone to peeling.

[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] Please refer to Figures 1-7, the utility model provides a technical solution: a steel structure hybrid prefabricated load-bearing wall panel, which consists of a prefabricated skeleton 100 and concrete formed by pouring with a matching formwork. The prefabricated skeleton 100 includes two channel steels 110 erected along the vertical direction and symmetrically distributed, and several beam reinforcement frameworks 130 horizontally penetrating and erected between the two channel steels 110. T-shaped frames 120 are arranged on the inner sides of the two channel steels 110 along their lengths. The beam reinforcement framework 130 includes four beam reinforcement components 1310 distributed in a rectangular array and several first stirrups 1320 surrounding and tying outside the four beam reinforcement components 1310. The ends of the beam reinforcement components 1310 sequentially penetrate through the T-shaped frames 120 and the channel steels 110 and are fixedly connected to the channel steels 110 through nuts 1330. The several first stirrups 1320 are evenly distributed at equal distances along the axial direction of the beam reinforcement components 1310.

[0036] Based on the above structural settings, this steel structure hybrid prefabricated load-bearing wall panel is composed of a prefabricated skeleton 100 and concrete. Among them, the prefabricated skeleton 100 and the concrete poured with a matching formwork form a prefabricated load-bearing wall panel. In the production process, the prefabricated skeleton 100 is first built, that is, several beam reinforcement frameworks 130 are erected between the two channel steels 110. The channel steels 110 not only serve as the support skeleton but also as the formwork on both sides during concrete pouring. After the beam reinforcement framework 130 is erected, the operator can use the nuts 1330 to realize the tensioning and fixing of the beam reinforcement components 1310 between the two channel steels 110. Then, the positions of the several first stirrups 1320 are adjusted, and the first stirrups 1320 are tied and fixed outside the four beam reinforcement components 1310 by means of steel wires. After the prefabricated skeleton 100 is built, the operator can cover and assemble the pouring formwork on the front and back of the prefabricated skeleton 100 and between the two channel steels 110, and finally pour the concrete. After forming, the operator only needs to remove the two front and back templates. At this time, a prefabricated load-bearing wall panel can be obtained. In addition, in the assembly process of the pouring formwork, the two flanges of the channel steel 110 can play an auxiliary positioning effect on the formwork. The formwork fits on the outer side of the flange of the channel steel 110. This steel structure hybrid prefabricated load-bearing wall panel, by arranging the T-shaped frames 120 along the length direction inside the channel steels 110, can ensure the firmness and stability of the channel steels 110 erected on the side of the concrete after concrete pouring. At the same time, replacing the current structurally weak connecting bars with the beam reinforcement framework 130 ensures the bearing capacity and stability of the structure. In addition, with the cooperation of the nuts 1330, the beam reinforcement components 1310 can be tensioned and erected between the two channel steels 110, and the installation is convenient.

[0037] Further, it further includes a column reinforcement structure 200 for splicing two side-by-side distributed prefabricated skeletons 100. The column reinforcement structure 200 is composed of a number of unit connecting frames 210 evenly erected at equal distances in the vertical direction. The unit connecting frame 210 includes two prefabricated frames 2110 symmetrically distributed and respectively arranged outside the two channel steels 110, and two second stirrups 2120 respectively surrounding and tying the top and bottom between the two prefabricated frames 2110. Among them, the column reinforcement structure 200, as the splicing skeleton structure of two side-by-side arranged prefabricated load-bearing wall panels, can be erected during on-site construction. Specifically, after the column reinforcement structure 200 is erected, formwork for casting can be respectively covered in front of and behind the column reinforcement structure 200 and between the two channel steels 110, and then the concrete pouring operation can be carried out.

[0038] Further, the prefabricated frame 2110 includes four U-shaped stirrup bars 2111 welded to the outside of the channel steel 110 in a rectangular array distribution. The four U-shaped stirrup bars 2111 are evenly divided into two groups and respectively welded with two second steel bars 2112 distributed left and right. The two second steel bars 2112 are both distributed in the vertical direction. Among them, the prefabricated frame 2110 can be prefabricated during the production process. By welding a number of U-shaped stirrup bars 2111 arranged in a double-row layout and in a rectangular array distribution on the outside of the channel steel 110, taking four U-shaped stirrup bars 2111 as a unit and cooperating with two second steel bars 2112, a number of prefabricated frames 2110 can be erected on the outside of the channel steel 110. During the on-site construction process, when the construction personnel erect the unit connecting frame 210, they only need to tie the two second stirrups 2120 to the top and bottom between the two prefabricated frames 2110 respectively with the help of steel wires.

[0039] Further, the T-shaped frame 120 is composed of a number of unit steel members 1210 evenly distributed at equal distances in the vertical direction, and an exhaust gap 1220 is reserved between any two adjacent unit steel members 1210. Among them, the T-shaped frame 120 is erected inside the channel steel 110 and can form an extended structure built into the concrete in cooperation with the poured concrete, thereby strengthening the connection strength of the channel steel 110. Preferably, by using a number of unit steel members 1210 to form the T-shaped frame 120, an exhaust gap 1220 is reserved between two adjacent unit steel members 1210, which helps the filling during concrete pouring.

[0040] Further, the beam reinforcement assembly 1310 includes a number of coaxially distributed first steel bars 1311, and any two adjacent beam reinforcement assemblies 1310 are connected by a steel bar sleeve 1312. Preferably, by using the beam reinforcement assembly 1310 composed of a number of first steel bars 1311 and a number of steel bar sleeves 1312, the operator can adjust the length of the beam reinforcement assembly 1310 according to the use requirements to adapt to the erection of prefabricated skeletons 100 of different lengths.

Therefore, the present utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present utility model should also fall within the protection scope of the claims of the present utility model.
