[0041] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown in

[0042] a steel structure composite wall in a preferred embodiment provided by the present invention includes columns 100, limit sleeves 200, cross bars 300, limit members 400 and wall panels 500. The columns 100 are arranged in a matrix. The upper end of the column 100 is provided with a slot 110, and the lower end is provided with an insertion portion 120. The insertion portion 120 of the upper column 100 is inserted into the slot 110 of the lower column 100 to realize the positioning connection of the adjacent upper and lower columns 100.

[0043] The limit sleeve 200 has a first state and a second state. The limit sleeve 200 is rotatably sleeved on the column 100 to realize the switching of the limit sleeve 200 between the first state and the second state. The limit sleeve 200 in the first state is used to limit the insertion portion 120, so that the insertion portion 120 is fixed in the corresponding slot 110, making the splicing of the adjacent upper and lower columns 100 stable. The limit sleeve 200 in the second state releases the limit on the insertion portion 120, so that the insertion portion 120 can be disengaged from the slot 110, that is, the limit sleeve 200 in the second state avoids the movement path of the insertion portion 120 disengaging from the slot 110.

[0044] The cross bar 300 is used to connect and fix two adjacent columns 100 horizontally. As Figure 10 shown, in different embodiments, cross bars 300 with appropriate lengths can be selected according to the size of the wall panel 500, and the lengths of the cross bars 300 at different positions can also be selected as needed.

[0045] The limit member 400 is installed on the column 100. The limit member 400 is used to limit the limit sleeve 200 in the first state to keep the limit sleeve 200 in the first state. The wall panel 500 is fixedly installed on one side of the column 100. Specifically, the wall panel 500 is fixedly installed on the front side of the column 100.

[0046] A steel structure composite wall provided by the present invention simplifies the connection process of columns by arranging a slot 110 at the upper end of a column 100 and an insertion part 120 at the lower end, enabling the insertion part 120 of the upper column 100 to be inserted into the slot 110 of the lower column 100. This plug-in connection method can achieve pre-positioning when not fully fixed, keeping the positions of the two columns 100 stable and providing a stable foundation for subsequent installation operations. The limit sleeve 200 limits the insertion part 120 in the first state, fixing the insertion part 120 in the corresponding slot 110 to ensure the stability of the connection of the column 100. In the second state, the limit sleeve 200 releases the limit on the insertion part 120, facilitating the disassembly and adjustment of the column 100. Moreover, the limit sleeve 200 can be rotated to achieve state switching, with flexible operation. This not only improves the flexibility of installation and disassembly but also ensures the reliability and stability of the connection part. Additionally, with the cooperation of the limiting member 400 to limit the limit sleeve 200 in the first state, the limit sleeve 200 is kept in the first state, ensuring that the limit sleeve 200 will not accidentally loosen during use and further improving the reliability of the connection of the column 100. Through the connection of the cross bar 300, the structural strength of the entire composite wall is further enhanced, improving the overall stability and seismic performance. The column connection in this application does not require complex welding or bolt connection, greatly improving the construction efficiency and reducing the construction cost.

[0047] Referring to Figure 8 , in some embodiments of the present invention, the column 100 includes a column body 130 and a column head 140. The column head 140 is connected to the upper end of the column body 130. The insertion part 120 is arranged at the bottom of the column body 130. The slot 110 extends downward from the upper end surface of the column head 140. The diameter of the column head 140 is larger than that of the column body 130, so that part of the column head 140 protrudes from the circumferential side of the column body 130, and there is enough space on the column head 140 to set the slot 110 for the insertion part 120 to insert.

[0048] Referring to Figure 8, in some embodiments of the present invention, the outer peripheral wall of the insertion portion 120 is provided with protruding strips 121 arranged in a uniformly spaced and circumferentially surrounding manner. The peripheral wall of the slot 110 is provided with a groove 111 for the protruding strips 121 to be inserted. It can be understood that the grooves 111 are also arranged in a uniformly spaced and circumferentially surrounding manner corresponding to the protruding strips 121 for the protruding strips 121 to be inserted one by one, so as to realize the positioning of the insertion portion 120. The slot 110 has a bottom wall for the bottom surface of the insertion portion 120 to contact, so as to limit the insertion depth. The outer peripheral wall of the column head 140 is provided with a relief notch 141 that is staggered from the groove 111. The groove 111 and the relief notch 141 are staggered in the circumferential direction; the limiting sleeve 200 is rotatably sleeved on the column body 130. The upper and lower ends of the limiting sleeve 200 are respectively provided with a limiting pressing block 210 and a limiting bottom block 220. The limiting pressing block 210 and the limiting bottom block 220 are arranged in a uniformly spaced and circumferentially surrounding manner. The limiting pressing block 210 and the limiting bottom block 220 are vertically aligned. The limiting bottom block 220 can vertically pass through the relief notch 141; when the limiting sleeve 200 is in the first state, both the limiting pressing block 210 and the limiting bottom block 220 are staggered from the relief notch 141. The bottom surface of the limiting pressing block 210 is attached to the upper end surface of the protruding strip 121, and the upper end surface of the limiting bottom block 220 is attached to the bottom surface of the column head 140. During installation, both the limiting pressing block 210 and the limiting bottom block 220 are arranged to be circumferentially staggered from the protruding strip 121. The limiting bottom block 220 is inserted into the relief notch 141 and moves vertically downward until the limiting pressing block 210 is flush with the upper end surface of the column head 140. At this time, the limiting sleeve 200 is in the second state. The limiting pressing block 210 and the limiting bottom block 220 are aligned with the relief notch 141 and are both circumferentially staggered from the protruding strip 121. Subsequently, the limiting sleeve 200 can be rotated so that the limiting sleeve 200 rotates to a position where the limiting pressing block 210 and the limiting bottom block 220 are staggered from the relief notch 141, so that the bottom surface of the limiting pressing block 210 is attached to the upper end surface of the protruding strip 121, and the upper end surface of the limiting bottom block 220 is attached to the bottom surface of the column head 140 protruding from the bottom surface of the column body 130, thereby realizing the pressing and fixing of the limiting pressing block 210 on the protruding strip 121, and the limiting bottom block 220 also restricts the vertical upward movement of the limiting sleeve 200, and also realizes the vertical fixation of the limiting sleeve 200, so that the upward acting force of the insertion portion 120 will be transmitted to the lower column 100 through the limiting sleeve 200, and the vertical acting force is prevented from acting on the limiting member 400, causing stress concentration or excessive force at the limiting member 400 and being easily damaged. Coupled with the fact that the limiting member 400 restricts the rotation of the limiting sleeve 200, the position fixation of the limiting sleeve 200 and the insertion portion 120 can be realized.

[0049] Referring to Figure 6 and Figure 9 , in a further embodiment of the present invention, the limiting sleeve 200 is provided with a limiting hole 230. The limiting member 400 is used to be inserted into the limiting hole 230 on the limiting sleeve 200 in the first state, so as to realize the circumferential fixation of the limiting sleeve 200, so that the limiting sleeve 200 cannot rotate randomly and thus deviate from the first state, making the connection between the upper and lower adjacent columns 100 stable.

[0050] Referring to Figure 5 、 Figure 6 and Figure 9 In a further embodiment of the present invention, a limiting hole 230 is provided at the bottom of the limiting sleeve 200, the column body 130 is provided with a mounting block 150, the limiting member 400 is an upright column elastically and movably mounted on the mounting block 150, and the upright column is subjected to an upward elastic force to insert into the limiting hole 230. Thus, under the action of the elastic force, the upright column is stably inserted into the limiting hole 230 to achieve stable limiting of the limiting sleeve 200. The upright column can move downward under an external force to disengage from the limiting hole 230, that is, the upright column can be manually or operated by a driving mechanism to move downward and disengage from the limiting hole 230 to unlock the limiting sleeve 200, facilitating subsequent disassembly.

[0051] Referring to Figure 5 In a further embodiment of the present invention, a through hole 151 is provided on the mounting block 150, the upright column passes through the through hole 151, and the cross-sectional profiles of the upright column and the through hole 151 are adapted to play a role of positioning and guiding. An insertion head 410 is provided at the upper end of the upright column. The insertion head 410 is used to insert into the limiting hole 230. A chamfer is provided at the top of the insertion head 410 so that the insertion head 410 can be inserted into the limiting hole 230 more smoothly, reducing structural interference. A convex ring 420 is provided at the bottom of the insertion head 410. The contour of the convex ring 420 is larger than that of the upright column. A spring 430 is sleeved on the upright column. The spring 430 is located between the mounting block 150 and the convex ring 420 to apply an upward elastic force to the convex ring 420 and the insertion head 410, so that when there is no external force, the insertion head 410 maintains the state of being inserted into the limiting hole 230. Since the force received by the column 100 hardly causes the limiting sleeve 200 to rotate, during use, the limiting sleeve 200 rarely gives a large force to the insertion head 410 due to a tendency to rotate. Therefore, the insertion head 410 is not easily damaged due to the force of the limiting sleeve 200 when inserted into the limiting hole 230.

[0052] Referring to Figure 4 and Figure 5 In a further embodiment of the present invention, a hook 600 is further included; a stud 440 is provided at the lower end of the upright column passing through the mounting block 150. The upper end of the hook 600 is sleeved on the stud 440, and a fastening nut 441 is threadedly connected to the stud 440 to fix the hook 600, thereby facilitating pulling the insertion head 410 out of the limiting hole 230 by operating the hook 600. Referring to Figure 5, in some embodiments of the present invention, a hook groove 610 is provided at the bottom of the hook 600, which is convenient for manual pulling. Additionally, during installation, the limit pressing block 210 can be hung in the hook groove 610, enabling the limit sleeve 200 to be hung on the hook 600. When the insertion portion 120 is inserted into the slot 110 in alignment, the limit sleeve 200 will not fall onto the area of the insertion portion 120 due to gravity, thus interfering with the insertion of the insertion portion 120 into the slot 110 in alignment. It can be understood that the limit pressing block 210 can rotate around the bottom of the hook 600 and enter the hook groove 610. The gap between adjacent limit pressing blocks 210 allows the hook 600 to be inserted, and an opening for the limit pressing block 210 to enter is provided on one side of the hook 600.

[0053] Refer to Figure 5 , in a further embodiment of the present invention, positioning posts 310 are provided at both ends of the crossbar 300, and positioning holes 160 for embedding the positioning posts 310 are provided on the upright post 100. The embedding of the positioning posts 310 into the positioning holes 160 realizes the positioning of the crossbar 300 and the upright post 100, facilitating the alignment of hole positions for installing fasteners. Connecting plates 320 are provided at both ends of the crossbar 300, and the connecting plates 320 are in contact with the side wall of the upright post 100. A hanging rod 510 is provided on the back of the wall panel 500, and a hanging groove 511 for embedding the crossbar 300 is provided on the hanging rod 510, thereby realizing the pre-positioning and support of the wall panel 500, and facilitating the hands to be freed for installing fasteners during installation. The hanging rod 510, the connecting plate 320, and the side wall of the upright post 100 are sequentially in contact and are provided with corresponding hole positions to be connected and fixed by fasteners, thereby realizing the connection and fixation of the three by fasteners. Of course, in order to prevent the crossbar 300 from being disconnected from the upright post 100 when the wall panel 500 is disassembled, an auxiliary fixing plate 340 is provided at the end of the crossbar 300, and the auxiliary fixing plate 340 and the upright post 100 are provided with corresponding hole positions to be connected and fixed by fasteners. The connecting plate 320 and the auxiliary fixing plate 340 are respectively provided on the upper and lower sides of the end of the crossbar 300.

[0054] Refer to Figure 7 and Figure 9 , in a further embodiment of the present invention, a central hole 170 is provided at the center of the upright post 100. The central hole 170 extends downward from the bottom wall of the slot 110 and penetrates through the upright post 100, and the cross-sectional contour of the central hole 170 is smaller than that of the slot 110. The bottom of the lowermost upright post 100 is connected with a mounting base 700, and the mounting base 700 is provided with an insertion post 710 that is embedded in the central hole 170, realizing the positioning installation of the mounting base 700. The mounting base 700 and the upright post 100 can be connected and fixed by fasteners or welding. The bottom of the mounting base 700 is provided with a pre-embedded portion 720, and the pre-embedded portion 720 is used to be inserted into the ground or concrete to provide the installation stability of the mounting base 700.

[0055] Refer to Figure 7 and Figure 9 , in a further embodiment of the present invention, the crossbar 300 is provided with connecting ears 330, which facilitate the diagonal bracing connection of the diagonal bracing rod.
