Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to an adjustable connecting beam and a cantilever scaffold provided with the adjustable connecting beam. Background Art

[0002] In existing technology, cantilever scaffolding is a simple facility used in construction, used for the main construction or decoration work and its safety protection needs. Currently, most construction projects have structural columns or shear walls at the corners. Ordinary cantilever scaffolding main beams will open holes in the structural columns or shear walls, which will cause significant 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 scaffolding main beams without drilling holes are installed at the corners of the structural columns or shear walls. Ordinary cantilever scaffolding main beams are installed in general locations and connected with connecting beams. However, because the triangular support cantilever frame main beam's force bearing system is a triangular system, the vertical load is transferred to the structural parts through the diagonal bracing, which does not produce large deflection. However, after long-term use, the ordinary cantilever frame main beam is affected by the vertical load and often produces a certain degree of deflection. This causes the connecting beam erected on both the triangular support cantilever frame main beam and the ordinary cantilever frame main beam to produce a certain degree of downward deflection on the side close to the ordinary cantilever frame main beam, resulting in longitudinal displacement of the vertical poles installed on the connecting beam, and then the entire cantilever scaffolding frame becomes unstable, posing a safety hazard. There are technical problems such as the downward deflection of the cantilever frame main beam causing the overall structural instability of the cantilever scaffolding and affecting construction safety.

[0020] 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 provided on a cantilever frame main beam 1, and also includes an adjustment mechanism 3. The adjustment mechanism 3 includes a fixing component 31 provided between the connecting beam body 2 and the cantilever frame main beam 1 and a plurality of lifting components 32 provided 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. The connecting beam body 2 is jointly pushed and supported by multiple adjusting mechanisms 3 to achieve better adjustment and support functions.

[0021] In this embodiment, the connecting beam body 2 is perpendicularly mounted to the cantilever frame main beam 1. The fixing member 31 comprises an arched plate, which can be made of bent steel sheet. Its weld-free construction ensures structural rigidity and stability during mounting. The arched plate is mounted on the cantilever frame main beam 1 and forms mounting slots 311 on either side of the cantilever frame main beam 1 to accommodate the lifting member 32. This embodiment features a simple structure, easy operation, and low manufacturing costs, making it suitable for widespread use.

[0022] The adjustable connecting beam in this embodiment can be applied to scaffolding and formwork support systems. By being installed on the cantilever frame main beam 1, there is no need to add openings on the side walls of the wall or column, so there is no increase in the risk of leakage from the openings; especially in areas 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 lifting 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 construction quality. It is easy to operate, has high installation efficiency, and can be disassembled and reused, which can ensure construction safety and construction quality; it has a simple structure and low production cost, and can be quickly promoted and applied to existing construction structures.

[0023] In this embodiment, the lifting component 32 includes two jacks connected to the fixing component 31. A friction pad can be placed on the top of the jack to increase stability when pushing the link beam body 2. The bottom of the jack can be connected to the mounting groove 311 via a mounting seat, enhancing the fixing effect and ensuring a stable lifting process. The installation method of the jack in the mounting groove 311 is conventional and will not be further described in this embodiment. Those skilled in the art can flexibly select and design it.

[0024] 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, thereby ensuring the 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 at the same time can withstand the reaction force when the jacking component 32 is pushed. It has a simple structure and low production cost. At the same time, it can play a good bearing role on the jacking component 32, and can be quickly disassembled after the construction is completed for easy reuse. The jacking 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, effectively solving the problem of misalignment of the uprights and instability of the overall structure caused by the cantilever frame main beam 1 being affected by the load during the construction process of traditional cantilever scaffolding.

Through adjustable beam splicing, the imbalance of beam splicing simultaneously built on triangular support cantilever beam 4 and cantilevered scaffold main girder 1 in traditional construction can be avoided, the structure is guaranteed to be stable while construction cost is low, construction quality is high, and the utility model can be widely used.

[0026] In the embodiment, the cantilevered scaffold provided with adjustable beam splicing further includes multiple vertical rods 6, the vertical rod 6 can be connected with the top of beam splicing body 2 and be arranged at the intersection of beam splicing body 2 and cantilevered scaffold main girder 1, the intersection is also provided with adjusting mechanism 3 to adjust the height of beam splicing body 2 and better stabilize the vertical rod 6, prevent the vertical rod 6 from deviating due to deflection of cantilevered scaffold main girder 1, and the adjusting mechanism 3 is arranged below the corresponding vertical rod 6 between beam splicing body 2 and cantilevered scaffold main girder 1; in other embodiments, the installation position of vertical rod 6 can be installed according to construction design, and only part is arranged at the intersection of beam splicing body 2 and cantilevered scaffold main girder 1.

[0027] In the embodiment, the number of vertical rods 6 is multiple, and the adjacent vertical rods 6 are stabilized by being provided with connecting rods 7, so that the connection and reinforcement between the structures can be better realized.
