[0001] The invention relates to the technical field of anti-falling and unloading of building facade scaffolding, in particular to an anti-falling and unloading cantilever scaffolding. Background Art

[0002] In the process of high-rise building construction, scaffolding is an indispensable temporary structure, which provides workers with an operating platform and material stacking space. However, the traditional scaffolding system has certain safety hazards, especially under high load or extreme weather conditions, the stability and safety of the scaffolding face severe challenges. In order to improve the load-bearing capacity and safety of the scaffolding, this technical solution proposes a cantilever scaffolding system with anti-falling and unloading.

[0003] Limitations of existing technology: Traditional cantilever scaffolding systems usually use a single-point support method. This design is prone to structural instability and even collapse when facing overload or dynamic load. In addition, the unloading capacity of traditional scaffolding is limited and it cannot effectively disperse and transfer loads, especially in high-rise building construction. This problem is particularly prominent. Summary of the invention

[0004] In order to solve the above problems, this technical solution proposes a new type of anti-falling unloading cantilever scaffolding system. The core of this system lies in the design of a double unloading device, which includes a load-bearing cantilever beam, an unloading cantilever beam and a force transmission device. Through this design, the scaffolding can effectively transfer the load to the load-bearing cantilever beam during normal use, and when overloaded, the force transmission device can buffer and unload the overload to the unloading cantilever beam, thereby providing a design bearing capacity exceeding 200% of the normal one, achieving the anti-falling effect of the scaffolding, and adopting the following technical solutions:

[0006] Furthermore, a connecting plate is provided at one end of the load-bearing cantilever beam, and the connecting plate is fixed to the side of the bottom beam of the building structure layer by tension bolts, and the other end is cantilevered. The load-bearing cantilever beam is provided with two webs parallel to each other, and the top plate and the bottom plate of the load-bearing cantilever beam are respectively provided with an upper through hole 1 and a lower through hole 1 at positions corresponding to those between the two webs, and the positions of the upper through hole 1 and the lower through hole 1 correspond to the settings of the vertical poles, and the vertical poles are respectively fixedly provided on the front and rear sides of the upper through hole 1 on the top plate of the load-bearing cantilever beam.

[0007] Furthermore, one end of the unloading cantilever beam extends into the building structure layer and is fixed by embedded parts, and the other end is cantilevered above the unloading cantilever beam. The unloading cantilever beam is provided with two parallel webs, and the top plate and the bottom plate of the unloading cantilever beam are respectively provided with upper through hole two and lower through hole two corresponding to the positions between the two webs, and the positions of the upper through hole two and the lower through hole two correspond to the settings of the vertical poles, and upper through hole three and lower through hole three, upper through hole four and lower through hole four are respectively provided on the top plate and the bottom plate of the unloading cantilever beam at the positions corresponding to the vertical poles.

[0010] The cantilevered I-beam and the force transmission device supported by the vertical pole of the present invention have the following significant beneficial effects:

[0011] (1) By setting up a double unloading device, when the scaffold is in normal use, it can carry out normal unloading to the load-bearing cantilever beam, share the bearing pressure of the scaffolding poles, achieve the purpose of overall unloading of the scaffolding, and improve the adaptability of the scaffolding to height. At the same time, when the scaffold is overloaded, its force transmission device can buffer and unload the overload to the unloading cantilever beam, that is, it can provide a design bearing capacity exceeding 200% of the normal one, achieving the effect of preventing the scaffold from falling;

[0012] (2) The load transfer is made incremental through the conduction of the unloading spring, thus avoiding the impact load transfer that causes serious damage to the unloading cantilever beam;

[0013] (3) Setting two columns as force transmission components can greatly improve the stability of the column and disperse the stress, thus avoiding stress concentration and causing a large bearing pressure on the load-bearing cantilever beam and the unloading cantilever beam;

[0014] That is, the double-stage unloading device of the present application can make the force transmission between the entire building facade scaffolding and the double-stage unloading device smoother, achieving unloading force transmission while also providing an anti-falling effect for the scaffolding.
