It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

Therefore, they do not have any technical substance. Any modification of the structure, change of the proportional relationship, or adjustment of the size, without affecting the efficacy that the present utility model can produce and the purpose that can be achieved, should still fall within the scope that the technical content disclosed by the present utility model can cover. At the same time, the terms such as "upper", "lower", "left", "right", "middle", and "one" cited in this specification are only for the convenience of clear narration and are not used to limit the scope of implementation of the present utility model. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope that the present utility model can implement.

[0034] As Figures 1-4 shown, an embodiment of the present utility model provides an assembled operation platform for steel structure construction fixed to the lower part of a steel column bracket, which includes four side frames 100 arranged in pairs opposite to each other, four bottom frames 200 respectively arranged at the bottom ends of the four side frames 100, and a bottom plate 300 arranged at the upper ends of the four bottom frames 200; the four side frames 100 are arranged around the outer surface of the steel structure square column and are connected to each other through connecting pieces 400; the four bottom frames 200 are arranged around the outer surface of the steel structure square column, are inserted and connected to each other, and form a limiting port 700 that matches the steel structure square column; the middle part of the bottom plate 300 has an assembly port 800 that matches the steel structure square column.

[0035] In the embodiment of the present utility model, through the cooperation of the four side frames 100 and the four bottom frames 200 under the action of the connecting pieces 400, various types of column sizes can be matched without worrying about size mismatches. The platform adopts a modular structural design, enabling rapid assembly and disassembly to form a stable auxiliary operation platform, thereby greatly improving construction efficiency; at the same time, the modular design enhances the adaptability and stability of the platform, ensuring the safe operation of construction workers, and can be widely applied to the installation, welding, inspection, or maintenance operations of various beam-column joints.

[0036] In the embodiment of the present utility model, the bottom plate 300 can be spliced by several platform plates, which is convenient for disassembly and assembly, easy to maintain, and also convenient for installation. At the same time, the platform plates can be rectangular, square, diamond-shaped, or other shapes, and no specific limitation is intended in this embodiment.

[0037] Specifically, as Figures 1-4As shown, in the embodiment of the present utility model, the connecting member 400 includes two ear plates 410 respectively arranged at opposite ends of adjacent two side frames 100. Through holes are provided on both of the two ear plates 410. The adjacent two side frames 100 are fixed by the opposite two ear plates 410 with bolts 420 and nuts 430. The bolt 420 passes through the through hole corresponding on the ear plate 410 and is fixed by the nut 430, that is, the two ear plates 410 are fixed to each other by the bolt 420 and the nut 430, thereby realizing the mutual fixation of the adjacent two side frames 100.

[0038] During specific use, first, the nut 430 is unscrewed from the bolt 420, then the distance between two adjacent side frames 100 is adjusted to meet the size of the steel structure square column. Subsequently, the previously removed nut 430 is screwed back onto the bolt 420, and then the nut 430 can be rotated until the bottom frame 200 abuts against the steel structure square column, thus completing the installation of the platform.

[0039] Based on the above solution, as Figures 1-4 shown, in the embodiment of the present utility model, a connection hole is provided at one end of each side frame 100, and a connection column 130 matching the connection hole is provided at the other end. Through the setting of the connection column 130 and the connection port, the adjacent two side frames 100 are spliced together into one body, further improving the stability of the side frame 100 and making it safer to use.

[0040] Specifically, as Figures 1-4 shown, in the embodiment of the present utility model, each side frame 100 includes several L-shaped beams 110 and several vertical beams 120. The several L-shaped beams 110 and the several vertical beams 120 are perpendicular to each other and cross-connected. Connection holes and connection columns 130 are respectively provided at both ends of the L-shaped beam 110. At the same time, the side frame 100 also forms a structure of a guardrail through the connection column 130 to protect the work safety of construction workers.

[0041] Based on the above solution, as Figures 1-4 shown, in the embodiment of the present utility model, a jack is provided on one of the adjacent two bottom frames 200, and a plug post 230 capable of matching the jack is provided on the other of the adjacent two bottom frames 200. Through the setting of the plug post 230 and the jack, the adjacent two bottom frames 200 are spliced together into one body, further improving the stability of the bottom frame 200 and making it safer to use.

[0042] Specifically, as Figures 1-4As shown in the figure, in the embodiment of the present utility model, each of the bottom frames 200 includes a cross beam 210 and a longitudinal beam 220. The cross beam 210 and the longitudinal beam 220 are perpendicularly connected to each other. The longitudinal beam 220 is disposed on the side frame 100. The four bottom frames 200 form a grid structure through four cross beams 210 and four longitudinal beams 220, so as to provide better stable support for the entire platform and facilitate adjustment to adapt to different steel column sizes.

[0043] Based on the above solution, as Figures 1-4 shown in the figure, in the embodiment of the present utility model, reinforcing plates 500 are disposed on both the side frame 100 and the bottom frame 200. The reinforcing plates 500 can effectively improve the strength and rigidity of the side frame 100 and the bottom frame 200, disperse the load, reduce their deformation under the action of external forces, and thus enhance the stability of the overall structure.

[0044] Based on the above solution, as Figures 1-4 shown in the figure, in the embodiment of the present utility model, a protective net 600 is disposed on each of the side frames 100. The protective net 600 is a common protective net in the technical field and will not be specifically set here. It can prevent sundries, tools or other items from falling from the side, reduce the risk of accidental injury. At the same time, the protective net 600 has the functions of ventilation and light transmission, which helps to keep the air circulation inside the frame and can also ensure sufficient lighting without affecting the working environment.

[0045] Based on the above solution, in an embodiment of the present utility model, a lifting ring is disposed on each of the side frames 100. During use, the hook of the crane can be hung on the lifting ring, and then the crane is started. The hook of the crane drives the lifting ring to move, and the lifting ring drives the side frame 100 and the bottom frame 200 to move, which is very convenient. At the same time, as a common steel structure main body, the steel column generally has fixed part structures with holes such as lifting lugs and mounting plates at its top, above or in the middle. Therefore, these fixed hole structures can be fully utilized, that is, the lifting lug and the lifting ring are connected through a steel cable, which can not only realize the rapid and safe erection of the aerial work platform, but also better fit the column surface and further improve the stability of the platform.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
