[0002] In the existing technology, cantilever scaffolding is a simple facility used in construction, which is used for the main construction or decoration work and its safety protection needs. At present, there are structural columns or shear walls at the corners of most construction projects. Ordinary cantilever frame main beams will open holes in the structural columns or shear walls, which will cause greater leakage risks. Sometimes they will pass through the hidden columns of the shear wall, affecting the safety of the structure. Therefore, based on the project situation, triangular support cantilever frame main beams that do not require drilling will be installed at the positive corners of the structural columns or shear walls, and ordinary cantilever frame main beams will be installed at general locations, and connected with connecting beams. However, since the force system of the triangle support cantilever frame main beam is a triangle system, the vertical load is transferred to the structural part through the diagonal brace, which will not produce a large deflection. However, after long-term use, the ordinary cantilever frame main beam is affected by the vertical load and often produces a certain deflection, which makes the connecting beam erected on the triangle support cantilever frame main beam and the ordinary cantilever frame main beam produce a certain downward deflection on the side close to the ordinary cantilever frame main beam, resulting in the longitudinal displacement of the vertical poles on the connecting beam, and then the whole cantilever scaffolding frame is unstable, posing a safety hazard. There are technical problems such as the downward deflection of the cantilever frame main beam, which leads to the instability of the overall structure of the cantilever scaffolding and affects the construction safety. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides an adjustable connecting beam and a cantilever scaffolding construction method provided with the adjustable connecting beam, which is particularly suitable for avoiding the overall structural instability of the cantilever scaffolding and ensuring construction safety without adding holes on the wall / column at low cost.

[0004] The technical solution adopted by the present invention is: an adjustable connecting beam, including a connecting beam body arranged on the cantilever frame main beam, and also including an adjusting mechanism, the adjusting mechanism includes a fixing component arranged between the connecting beam body and the cantilever frame main beam and a plurality of lifting components respectively arranged on both sides of the cantilever frame main beam and connected to the fixing component, each lifting component can push the connecting beam body to adjust the height of the connecting beam body.

[0005] Furthermore, the connecting beam body is vertically arranged with the cantilever frame main beam, and the fixing component comprises an arched plate, which is erected on the cantilever frame main beam and forms mounting grooves capable of bearing the jacking components on both sides of the cantilever frame main beam.

[0006] Further, the lifting component includes a jack connected to the fixing component.

[0007] Further, the number of the lifting components is two.

[0008] Furthermore, the present invention also provides a cantilever scaffolding construction method provided with an adjustable connecting beam, comprising the following steps:

[0010] When the main beam of the cantilever frame deflects downward, the height of the connecting beam body is adjusted by the jacking component to stabilize the structure of the cantilever scaffolding.

[0011] Further, the step of installing a plurality of uprights to form a cantilever scaffold comprises:

[0012] When the vertical rod is connected to the top of the connecting beam body and the vertical rod is arranged at the intersection of the connecting beam body and the main beam of the cantilever frame, an adjustment mechanism is arranged at the intersection to stabilize it.

[0026] like Figures 1 to 3 As shown, a schematic diagram of an embodiment of an adjustable connecting beam of the present invention includes a connecting beam body 2 arranged on a cantilever frame main beam 1, and also includes an adjusting mechanism 3, the adjusting mechanism 3 includes a fixing component 31 arranged between the connecting beam body 2 and the cantilever frame main beam 1 and a plurality of lifting components 32 respectively arranged on both sides of the cantilever frame main beam 1 and connected to the fixing component 31, each lifting component 32 can push the connecting beam body 2 to adjust the height of the connecting beam body 2. In this embodiment, each adjustable connecting beam includes one adjusting mechanism 3; in other embodiments, the number of adjusting mechanisms 3 can be set to multiple according to the length of the connecting beam body 2, multiple adjusting mechanisms 3 are fixed on the corresponding cantilever frame main beam 1 and are commonly connected to one connecting beam body 2, and the connecting beam body 2 is jointly pushed and supported by multiple adjusting mechanisms 3 to achieve better adjustment and support functions.

[0027] In this embodiment, the connecting beam body 2 is vertically arranged with the cantilever frame main beam 1, and the fixing component 31 includes an arched plate, which can be made of steel plate material and bent, and the structure without welding points can ensure the structural rigidity and stability during fixing. The arched plate is set on the cantilever frame main beam 1 and forms mounting grooves 311 on both sides of the cantilever frame main beam 1 that can carry the jacking component 32. This embodiment has a simple structure, convenient operation, low processing cost, and is easy to promote and use.

[0028] The adjustable connecting beam in this embodiment can be applied to scaffolding and formwork support systems. By setting up the installation method on the cantilever frame main beam 1, there is no need to add openings on the side walls of the walls or columns, so there is no increase in the risk of leakage from the openings; especially in places adjacent to structural columns or shear walls, for construction where only ordinary cantilever frame main beams can be built on the formwork, the height of the connecting beam body 1 can be adjusted at any time through multiple jacking components 32, which can avoid the overall structural instability of the cantilever scaffolding caused by the deflection of the ordinary cantilever frame main beam 1, thereby ensuring construction safety and quality, and is easy to operate, highly efficient to install, and removable and reusable, thereby ensuring construction safety and quality; it has a simple structure and low manufacturing cost, and can be quickly promoted and applied to existing construction structures.

[0029] In this embodiment, the lifting component 32 includes a jack connected to the fixing component 31, and the number of the lifting components 32 is two. A friction pad can be set on the top of the jack to increase the stability when pushing the link beam body 2, and the bottom of the jack can be connected to the mounting groove 311 through the mounting seat to improve the fixing effect and ensure the stability of the lifting process. The installation method of the jack in the mounting groove 311 is a prior art, which will not be described in this embodiment, and those skilled in the art can flexibly select and design it.

[0030] The adjustable connecting beam in this embodiment can be quickly erected on the cantilever frame main beam 1 by utilizing an arched plate platform made of steel plates. The installation method is simple and quick, and there is no need to add openings on the sides of the surrounding walls or columns, which avoids leakage hazards and ensures construction quality. The arched structure made of steel plates has strong rigidity, which can ensure that the structure of the fixing component 31 itself is stable when the connecting beam body 2 is pushed, and can withstand the reaction force when the lifting component 32 is pushed. It has a simple structure and low manufacturing cost, and can also play a good bearing role on the lifting component 32. After the construction is completed, it can be quickly disassembled for easy reuse. The lifting component adopts a jack, the material is universal, and the structure is easy to promote. The level and height of the connecting beam body 2 can be effectively adjusted by the jack, and it plays a stable supporting role, which effectively solves the problem of misalignment of the uprights and instability of the overall structure due to the deflection of the cantilever frame main beam 1 under the influence of load during the construction of traditional cantilever scaffolding.

[0031] On the other hand, the present invention also provides a cantilever scaffolding construction method provided with an adjustable connecting beam, comprising the following construction steps:

The triangular support cantilever beam 4 is connected to at least one cantilever frame main beam 1 through an adjustable connecting beam. The length of each connecting beam body 2 can be selected and adapted according to the number and mutual spacing of the corresponding cantilever frame main beams 1, and an adapted number of adjustment mechanisms 3 are installed. The triangular support cantilever beam 4 is better able to bear the load and is fixed at the positive corner through the diagonal brace in the triangular structure. Usually, after completing the above construction, multiple vertical poles 6 are installed to form a cantilever scaffolding;

[0033] When the cantilever frame main beam 1 deflects downward, the height of the connecting beam body 2 is adjusted by the jacking component 32 to stabilize the structure of the cantilever scaffolding.

[0034] The cantilever scaffolding provided with the above-mentioned adjustable connecting beam is better suitable for construction with 5 walls / columns, does not require openings in the walls / columns 5, and ensures that the structure of the cantilever scaffolding is stable, easy to operate, adjustable at any time, and can be widely used on the cantilever frame main beam 1 built on the template around the wall / column 5. The adjustable connecting beam can avoid the imbalance of the connecting beams built on the triangular support cantilever beam 4 and the cantilever frame main beam 1 in traditional construction, ensures structural stability, low construction cost, high construction quality, simple structure, low manufacturing cost, and can be widely used.

[0035] When the vertical pole 6 is connected to the top of the connecting beam body 2 and the vertical pole 6 is arranged at the intersection of the connecting beam body 2 and the cantilever frame main beam 1, an adjustment mechanism 3 is set at the intersection, and the installation position of the vertical pole 6 can be installed according to the construction design. It can be partially arranged at the intersection of the connecting beam body 2 and the cantilever frame main beam 1, and the other part can be installed on the template, or only installed on the cantilever frame main beam 1, etc. It can be installed according to the construction design.

[0036] In this embodiment, the vertical pole 6 arranged at the top of the intersection of the connecting beam body 2 and the cantilever frame main beam 1 is provided with an adjustment mechanism 3 below it to better adjust the vertical position of the vertical pole 6.

[0037] There are multiple vertical poles 6, and connecting rods 7 are arranged between adjacent vertical poles 6 for stability, so as to better realize the connection and reinforcement between the structures.
