[0034] To describe the technical content, achieved objectives and effects of the present invention in detail, the following is described in conjunction with the embodiments and with reference to the drawings.

[0035] Please refer to Figures 1 to 4 , the specific embodiment of the present invention relates to a steel column operation platform, including:

[0036] The steel column body 1, the shape of the steel column body 1 is a cuboid;

[0037] The connecting plates 2, a plurality of the connecting plates 2 are symmetrically welded to the Y-side surface of the steel column body 1 respectively. The connecting plates 2 are parallel to the X-side surface of the steel column body 1, and one or more first connecting holes 21 are provided on the connecting plates 2;

[0038] The platform bracket 3, the platform bracket 3 includes columns 31, a supporting cross beam 32 and a limiting column 33. The number of the columns 31 is 2, the transverse cross section of the columns 31 is L-shaped, and each of the columns 31 is provided with a second connecting hole 311 corresponding to the first connecting hole 21 on the connecting plate 2 one by one; the number of the supporting cross beams 32 is 2, the longitudinal cross section of the supporting cross beam 32 is L-shaped, one side of the supporting cross beam 32 extends vertically upward, one end of the supporting cross beam 32 is perpendicularly welded to the lower end of the column 31, and the lower end of the limiting column 33 is perpendicularly connected to the other end of the supporting cross beam 32;

[0039] The operation platform body 4, the operation platform body 4 includes a base 41 and a guardrail 42 connected to the upper part of the base 41. Two or more limiting angle steels 43 arranged along the Y direction are connected to the lower part of the base 41. One side of the limiting angle steel 43 extends vertically downward, and a notch 431 is provided on the vertically downward extending side of the limiting angle steel 43. The notch 431 is in limiting cooperation with the vertically upward extending side of the supporting cross beam 32.

[0040] In the above embodiments, as a preferred solution, a chamfer can be provided at the opening of the notch 431 of the limiting angle steel 43 to make the notch 431 and the vertically upward extending side of the supporting cross beam 32 easier to be in limiting cooperation connection.

[0041] In the above embodiments, by pre-welding the connecting plate 2 on the steel column, the first connecting holes 21 are reserved on the connecting plate 2. When construction is required on the side of the steel column adjacent to the exterior wall, the platform bracket 3 can be hoisted by a tower crane to a position where the second connecting holes 311 on the column 31 correspond one by one to the first connecting holes 21, and bolts are respectively passed through the first connecting holes 21 and the second connecting holes 311 to lock and fix. Then, according to the need, the operation platform body 4 of the required model can be selected and erected on the platform bracket 3. Since the longitudinal section of the supporting cross beam 32 of the platform bracket 3 is L-shaped, with one side extending upward, and the lower part of the operation platform body 4 is provided with a limiting angle steel 43, and a notch 431 is provided on the side of the limiting angle steel 43 extending vertically downward, the Y-direction limitation of the operation platform body 4 is realized through the limiting cooperation between the notch 431 and the supporting cross beam 32, and the X-direction limitation of the operation platform body 4 is realized through the limiting column 33. During disassembly, first remove the operation platform body 4 on the platform bracket 3, and then remove the bolts connecting the platform bracket 3 and the connecting plate 2 to remove the platform bracket 3. The above structure is convenient for installation and disassembly, and can flexibly replace the operation platform body 4 of different sizes and models according to different application scenarios.

[0042] Please refer to Figure 2 , as an alternative embodiment, further includes:

[0043] A positioning mechanism 5, the positioning mechanism 5 is arranged in the middle of the X-direction side of the steel column body 1; the positioning mechanism 5 includes a magnet 51 and a limiting jack 52, the magnet 51 is located above the limiting groove, and the limiting jack 52 is arranged in the vertical direction;

[0044] A positioning cross beam 44, the positioning cross beam 44 is connected between the two columns 31;

[0045] A positioning plug-in 45, the positioning plug-in 45 is connected to the middle of the positioning cross beam 44, the material of the positioning plug-in 45 is iron, and the shape of the positioning plug-in 45 is adapted to the shape of the limiting jack 52.

[0046] In the above embodiments, when the platform bracket 3 is lifted by a tower crane to a position close to the connection position of the column 31, preliminary positioning can be first carried out through the magnet 51 and the positioning plug-in 45. During preliminary positioning, the iron positioning plug-in 45 approaches the magnet 51 and attracts each other with the magnet 51 to realize the preliminary Y-direction positioning of the X-plane of the platform bracket 3 and the column 31. Then, the tower crane controls the platform bracket 3 to move downward. Since the shear force of the suction force of the magnet 51 on the positioning plug-in 45 is less than the gravity of the platform bracket 3 itself, the positioning plug-in 45 is inserted into the limiting jack 52 to realize the preliminary positioning connection between the platform bracket 3 and the column 31. At this time, the second connecting holes 311 just correspond one by one to the first connecting holes 21, which is convenient for the operation of locking with bolts.

[0047] Please refer toFigure 4 , as an optional implementation manner, the positioning plug 45 is wedge-shaped.

[0048] In the above implementation manner, the wedge-shaped design of the positioning plug 45, that is, the design with a larger upper part and a smaller lower part, on the one hand, enables the positioning plug 45 to be more easily inserted into the limit jack 52 to achieve accurate positioning. On the other hand, the wedge-shaped structure design enables the positioning plug 45 to be closer to the magnet 51, facilitating its preliminary magnetic positioning with the magnet 51.

[0049] , as an optional implementation manner, a vertical through groove 521 is provided in the middle of the side wall of the limit jack 52 facing the X-direction side.

[0050] In the above implementation manner, since a vertical through groove 521 is provided in the middle of the side wall of the limit jack 52 facing the X-direction side, the through groove 521 enables the limit jack 52 to slightly deform outward when being inserted and matched with the positioning plug 45, so as to connect with the positioning plug 45 in an interference fit, making the positioning connection between the positioning plug 45 and the limit jack 52 more stable and further facilitating the subsequent fixing of the bolt.

[0051] , as an optional implementation manner, the X-direction side surface of the magnet 51 is an inclined surface 511 that slopes downward.

[0052] In the above implementation manner, the inclined surface 511 design of the magnet 51 enables more accurate positioning when it is preliminarily magnetically positioned with the positioning plug 45, and the positioning plug 45 can be more easily inserted into the limit jack 52 along the inclined surface 511.

[0053] , as an optional implementation manner, the slope of the inclined surface 511 is 70 - 85 degrees.

[0054] In the above implementation manner, the inclined surface 511 design of the magnet 51 enables more accurate positioning when it is preliminarily magnetically positioned with the positioning plug 45, and the positioning plug 45 can be more easily inserted into the limit jack 52 along the inclined surface 511.

[0055] , as an optional implementation manner, a diagonal brace 34 is welded between the supporting cross beam 32 and the column 31.

[0056] In the above implementation manner, the diagonal brace 34 can improve the structural stability of the platform bracket 3.

[0057] , as an optional implementation manner, a first lifting hole 35 for hoisting is provided on the diagonal brace 34.

[0058] In the above implementation manner, the first lifting hole 35 is arranged at the center of gravity of the platform bracket 3, making its hoisting more stable.

[0059] As an alternative embodiment, a second lifting hole 46 for hoisting is provided in the upper part of the guardrail 42.

[0060] In the above embodiments, the second lifting hole 46 is arranged at the center of gravity of the operation platform body 4 to make the lifting more stable.

[0061] As an alternative embodiment, the number of the connecting plates 2 is four, and the four connecting plates 2 are symmetrically distributed in pairs on the two Y-side surfaces of the steel column body 1.

[0062] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in the related technical field, shall be similarly included in the patent protection scope of the present invention.
