[0032] In some embodiments, each set of dismantling tools in this embodiment is generally equipped with a support frame 1 and a patterned panel 7. The support frame 1 is generally assumed to be between two steel cantilever beams 8, with the distance between the two steel cantilever beams 8 generally around 1500mm. The length of the support frame 1 and the patterned panel 7 is generally around 3000mm, which can meet the requirement of a multiple of 1500 for the steel spacing. The width is around 300mm, which can meet the requirement of an 800mm spacing between uprights. The support frame 1 is generally made of L40×4 aluminum alloy angle steel welded to the aluminum plate (patterned panel 7), or angle steel welded to the patterned steel plate. Aluminum alloy material is preferred because it is relatively lightweight and easier to assemble and disassemble. Each support frame 1 is generally equipped with four connecting support components 3. Each connecting support component 3 is generally made of reinforced 40×40×4 aluminum alloy square steel tube or steel tube. The outer side wall of the upper crossbeam 301 of the connecting support component 3 is close to the inner side wall of the long side of the support frame 1 and is connected by bolts.

[0033] In some embodiments, each connecting support assembly 3 includes a vertical beam 302 and a lower horizontal beam 303; the upper end of the vertical beam 302 is perpendicularly connected to one end of the upper horizontal beam 301; one end of the lower horizontal beam 303 is perpendicularly connected to the lower end of the vertical beam 302; wherein the length of the lower horizontal beam 303 is greater than the length of the upper horizontal beam 301, and the upper horizontal beam 301, the vertical beam 302 and the lower horizontal beam 303 form a U-shaped structure.

[0034] In some embodiments, each connecting support assembly 3 includes a plurality of connecting holes 304 and pin holes 305; the plurality of connecting holes 304 are disposed on the side wall of the upper crossbeam 301 and penetrate through the side wall of the upper crossbeam 301, and the connecting holes 304 are used to connect to the long side of the support frame 1 by bolts; the pin holes 305 are disposed on the upper plane of the other end of the lower crossbeam 303 and penetrate vertically through the upper crossbeam 301; wherein the top view projection of the other end of the upper crossbeam 301 covers the pin holes 305.

[0035] In some embodiments, the connecting support assembly 3 can be designed in various sizes to accommodate different steel cantilever beams 8, such as 16# I-beams or 20# I-beams. Furthermore, this invention allows for the splicing and use of multiple sets of dismantling tools, such as... Figure 3 The image shows an example of two sets used together.

[0036] In some embodiments, the dismantling tools for the steel cantilever frame also include connecting pins 5 and anti-fall chains 6; the connecting pins 5 pass through the pin holes on the long side of the patterned panel 7 and the support frame 1, and then pass through the pin holes 305 on the lower crossbeam 303; one end of the anti-fall chain 6 is connected to the upper end of the connecting pins 5, and the other end is connected to the long side of the support frame 1 and the patterned panel 7. The anti-fall chain 6 is used to prevent the connecting pins 5 from falling after they are pulled out.

[0038] In some embodiments, one sidewall of the stiffener 2 is adjacent to the sidewall of the steel cantilever beam 8. Please refer to [link to relevant documentation]. Figure 6 .

[0039] In some embodiments, the dismantling tool for the steel cantilever frame also includes a handrail 4, which has a U-shaped structure and is located on one long side of the support frame 1. The lower ends of both sides of the handrail 4 have external threads, which are locked by double nuts 402 after passing through the patterned panel 7 and the long side of the support frame 1.

[0040] In some embodiments, the handrail 4 also includes a nut 401, which is located at the root of the external thread at the lower end of the handrail 4 and pressed onto the patterned panel 7. The external thread passes through the nut 401, the patterned panel 7, and the long side of the support frame 1, and is then locked by double nuts 402.

When moving, the connecting pin 5 in one side of the tool is pulled out first. The operator stands on the other side of the tool and moves the previous steel section in front to perform the same action to fix it. After the operator is in position, the other tool behind is moved to be connected in parallel with the previous tool and fixed in place.

[0044] In summary, the dismantling tool for the steel cantilever frame of this utility model has the following advantages: This solution utilizes the original steel cantilever beams of the building, sets up connecting support components on the steel cantilever beams, and then connects and lays support frames and patterned panels on the connecting support components. The connecting support components are connected to the long side of the support frame with bolts. The patterned panels and support frames can be connected by welding, riveting, or bolting. The entire dismantling tool is prevented from falling off the radial direction and cantilever end of the steel cantilever beam by pluggable anti-falling pins, anti-falling chains, and anti-falling steel bars. At the same time, a handrail is set on one side of the dismantling tool between two steel cantilever beams for dismantling personnel to hold on to and fasten safety belts, ensuring personnel safety. This solution not only reduces the risk of safety hazards caused by the lack of open operating space that prevents personnel from operating the installation and dismantling of steel, but also the device is lightweight, easy to operate and construct, safe and reliable, and strengthens the safety management of the construction site.
