In the description of the present utility model, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

The existing overhanging components on the outer side of the high-rise building can be used for building an auxiliary operation platform during construction, the operation platform is generally formed by combining various steel pipes and fasteners, workers are located in the high air, the installation is difficult, a certain risk exists, in addition, in the installation or disassembly process, if a phenomenon of hand sliding occurs, the phenomenon of high-altitude falling is likely to occur, and the overhanging components are extremely unsafe for building construction, so that the scheme provides the following technical scheme for solving the technical problems:

referring to fig. 1 to 5, a side operation platform for installing overhanging components is provided on a steel beam a and a steel column B of a steel structure, and specifically includes: the inclined support component 1 is welded on the steel column B; an operation platform 2 with one side of the bottom arranged above the diagonal support component 1, wherein the operation platform 2 comprises a platform body 21 and a reverse matching piece 22 welded at the bottom of the platform body 21, and the diagonal support component 1 is abutted against the inner side of the reverse matching piece 22; a locking member 3 locked between the diagonal support member 1 and the reverse fitting member 22; a guardrail 4 locked above the platform body 21 by screws; and one end of each diagonal draw bar 5 is locked on one side of the top of the operating platform 2, and the other end of each diagonal draw bar 5 is welded on the steel beam A.

Firstly, in the embodiment, the side operation platform is divided into the operation platform 2 and the guard rail 4, in the arrangement of the operation platform 2, the platform body 21 and the reverse matching piece 22 are combined in a welding manner, the guard rail 4 and the platform body 21 are fixed in a screw locking manner, the connection processes are all performed in factories or the ground in advance, and workers do not need to perform electric welding in the high air in a pretreatment manner, so that the installation difficulty of the workers is reduced.

Subsequently, the worker needs to map the steel beam A and the steel column B on the steel structure, calculates fixed nodes on the steel beam A and the steel column B in advance, and welds the inclined support component 1 and the inclined pull rod 5 on the steel column B and the steel beam A respectively, and the risk of falling objects is lower when welding because the inclined support component 1 and the inclined pull rod 5 are large components.

After the welding process is finished, at this time, the operation platform 2 and the guardrail 4 can be hoisted between the steel beam A and the steel column B through a tower crane or other hoisting devices, the locking effect is formed between the diagonal draw bar 5 and the operation platform 2 or the guardrail 4, and then the diagonal support assembly 1 and the reverse matching piece 22 are fixedly connected through the locking piece 3, so that the whole operation platform 2 and the guardrail 4 are fixed from the upper end and the lower end, workers only need to finish the welding of two points and the locking fixation of the two points in a high-altitude environment, the whole installation work can be finished, the installation speed is high, the working procedure is simple, the whole working strength can be greatly reduced when the steel beam is dismounted, and the condition that small fasteners and small steel pipes drop is not worried about in the installation or the dismounting process is avoided because of only three assemblies.

It can be seen from the figure that, in practice, the platform body 21 is a plate-shaped structure, a worker performs construction thereon, but it is impossible to always stand on the same point to perform construction, so that the supporting force on the whole platform body 21 should be balanced, so that the worker can be uniformly stressed no matter where the worker walks to each position on the platform body 21, in order to achieve such effects, the diagonal bracing assembly 1 is disposed on the right side of the bottom of the platform body 21, and the diagonal bracing 5 is disposed on the left side of the top of the platform body 21, and the whole platform body 21 is tightly tied through connection of the diagonal bracing assembly 1 and the diagonal bracing 5, so that no matter where the worker walks to the platform, the worker can be supported by one of the tie assemblies.

On the basis of the above, if the diagonal member 5 is far away from the fixing node of the diagonal member 1, the worker can support the diagonal member on the platform body 21, but if the worker moves greatly, the whole platform body 21 may shake, so as to improve the stability of the platform body 21, the diagonal member 5, the fixing node of the steel beam a, the fixing node of the diagonal member 1 and the fixing node of the steel column B are located on the same vertical line, so that the two fixing nodes are close to each other as much as possible, the distance between the two fixing nodes is reduced, and the drawknot effect of the diagonal member 5 and the diagonal member 1 on the platform body 21 is improved, so that the platform body 21 can be more stable, and the shaking does not easily occur even if the worker moves greatly.

In this embodiment, the reverse fitting member 22 is a plurality of L-shaped clamping plates, the reverse fitting member 22 includes a first folding portion 221 that is fitted with the locking member 3, a second folding portion 222 that is bent and extended by 90 ° with respect to the first folding portion 221, a folding angle formed by the second folding portion 222 and the first folding portion 221 is used for placing the diagonal support assembly 1, as can be seen from the figure, the distance between the L-shaped clamping plates is not far, the diagonal support assembly 1 can be clamped between the two first folding portions 221, the second folding portion 222 mainly has an abutting effect, and the two first folding portions 221 form a restriction on the diagonal support assembly 1 at the left end and the right end, but a certain movable space is still provided for the diagonal support assembly 1 at the front end and the rear end, so that the locking member 3 is also introduced.

In the conventional diagonal support assembly 1, only a simple diagonal brace is often used for supporting and tying, but in the embodiment, because the diagonal support assembly 1 needs to be matched with the reverse matching piece 22, a gap is easy to appear between the two by adopting a direct insertion mode of the diagonal brace, so the diagonal support assembly 1 comprises a first support rod 11 welded on the steel column B, a second support rod 12 welded on the first support rod 11 and having 45 degrees, and the second support rod 12 is clamped between two adjacent first folding parts 221, wherein the second support rod 12 is matched with the reverse matching piece 22, and the first support rod 11 plays a role of the diagonal brace, so that the whole diagonal support assembly 1 can be matched with the reverse matching piece 22 better, and meanwhile, the diagonal support effect of the diagonal support assembly can be played.

In order to protect guardrail 4 in the lateral direction, simultaneously, can carry out the drawknot cooperation with platform body 21 again, diagonal draw bar 5 is provided with two sets of locks respectively in the outside of platform body 21, along the diagonal of guardrail 4 extends and welds on girder steel A, and the drawknot support can be carried out from the top, the lateral direction of platform body 21 to two sets of symmetrical diagonal draw bars 5 to improve the stability of platform body 21.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, and various modifications and variations may be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
