Description

Technical Field

[0001] The utility model relates to the field of scaffolding, in particular to a novel door-type scaffolding device. Background Art

[0002] The existing traditional scaffolding system usually uses round steel pipes as the main structural material, combined with clamps and other connectors for overlap assembly. Although this scaffolding system can meet the needs of engineering construction to a certain extent, it also has many problems and challenges.

[0003] First, due to the design characteristics of components such as round steel pipes and clamps, the construction of this scaffolding requires the collaboration of multiple workers. This not only increases labor costs, but also reduces work efficiency. In the fast-paced, high-efficiency modern construction environment, this is obviously a significant disadvantage.

[0004] Secondly, the process of erecting and disassembling such scaffolding is relatively complicated and time-consuming. Workers need to connect and fix each component one by one to ensure the stability and safety of the scaffolding. However, this cumbersome operation not only takes up a lot of time, but also may increase safety risks due to human factors (such as fatigue, negligence, etc.). Therefore, it is necessary to provide a new type of portal scaffolding device to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a novel door-type scaffolding device.

[0006] The utility model provides a novel portal scaffolding device, comprising four columns, adjacent columns are connected by a plurality of connecting rod assemblies, the columns and the connecting rod assemblies surround a rectangular structure, and the columns are located at the vertices of the rectangular structure, the connecting rod assembly comprises a U-shaped plate, the inner side of the U-shaped plate is hinged with two support rods through a hinge shaft, and one end of the support rod away from the U-shaped plate is hinged with the corresponding column, the top of the support rod is provided with a first plane, and the inner side of the U-shaped plate is provided with a second plane matching the first plane.

[0007] By adopting the above technical solution, the device is composed of four columns, which are located at the four vertices of the rectangular structure, ensuring basic structural stability. Adjacent columns are connected by connecting rod assemblies, further enhancing the stability of the overall structure.

[0008] Preferably, a mounting hole is provided on the U-shaped plate, and a threaded hole is provided on the support rod opposite to the mounting hole.

[0009] By adopting the above technical solution, the U-shaped plate is connected and fixed to the support rod by screws, so that the scaffolding is more stable.

[0010] Preferably, when the two support rods of the same group are on the same horizontal plane, the first plane is in contact with the second plane. The contact between the first plane and the second plane enhances the stability and load-bearing capacity of the structure and facilitates the positioning of the scaffold after it is unfolded.

[0011] By adopting the above technical solution, this contact not only increases the stability of the scaffolding, but also improves its load-bearing capacity to a certain extent.

[0012] Preferably, two adjacent side walls of the columns are both fixed with fixing rods, ends of the fixing rods are fixed with mounting plates, and the mounting plates are provided with a plurality of connecting holes for connecting with the wall.

[0013] By adopting the above technical solution, the mounting plate can be fixed to the wall by means of expansion bolts, so that the scaffolding is more stable.

[0014] Preferably, the bottom of the column is connected to a threaded column by a thread, the bottom end of the threaded column is fixed with a support plate, a nut is fixed on the support plate, and the nut is concentric with the threaded column.

[0015] By adopting the above technical solution, the height of each column can be adjusted with the help of a wrench.

[0016] Compared with the related art, the utility model provides the following beneficial effects:

[0017] The scaffolding can be folded and does not need to be completely disassembled after use. It can be folded by simply unscrewing the corresponding screws. It can be quickly built without excessive workers. Moreover, for some low-load usage scenarios, screws do not need to be installed, which is more convenient and safer.

[0018] The design of the mounting holes on the template and the threaded holes on the support rods makes the installation of the connecting rod assembly more convenient and firm. At the same time, the multiple connection holes on the mounting plate can be easily connected to the wall, further enhancing the stability of the scaffolding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0023] Please refer to Figure 1 to Figure 2 A new type of portal scaffolding device, whose remarkable features are reflected in its structure, mainly includes four columns 1. The positions of these columns 1 relative to each other are carefully designed, and they are connected by a number of connecting rod assemblies 2, which not only ensures the stability of the structure, but also makes the whole device form a regular rectangular structure. It is particularly worth mentioning that the four columns 1 are located at the four vertices of this rectangular structure, thereby maximizing the overall stability of the scaffolding.

[0024] Further detailed observation shows that each set of connecting rod assembly 2 includes a key U-shaped plate 21. The U-shaped plate 21 is connected to two support rods 23 on its inner side through a hinge shaft 22. This design allows the support rods 23 to rotate freely within a certain range. At the same time, the other ends of the two support rods 23 are connected to the corresponding columns 1 through a hinged manner, thereby ensuring the flexibility of the scaffolding and the stability after folding and unfolding.

[0025] In addition, the designer also specially sets a first plane 24 on the top of the support rod 23, and matches it with a second plane 25 on the inner side of the U-shaped plate 21. The design of these two planes is very clever, and they can cooperate with each other under certain conditions to further enhance the stability of the scaffolding.

[0026] In view of the detailed structure of the connecting rod assembly 2, a mounting hole 26 is specially provided on the U-shaped plate 21. This design is mainly for the convenience of installation and fixing. At the same time, a threaded hole 27 is also correspondingly provided on the support rod 23, and this position just corresponds to the mounting hole 26 on the U-shaped plate 21. Such a design can make the connecting rod assembly 2 more convenient and firm during installation through screws.

[0027] When the two support rods 23 of the same group are adjusted to be on the same horizontal plane, the first plane 24 mentioned above will be in close contact with the second plane 25. This contact not only increases the stability of the scaffold, but also improves its load-bearing capacity to a certain extent.

[0028] In order to further enhance the connection stability between the scaffolding and the construction wall, the designer fixed fixing rods 3 on the side walls of two adjacent columns 1. The ends of these fixing rods 3 are equipped with a mounting plate 31, and each mounting plate 31 is provided with a plurality of connection holes 32, which can be firmly connected to the wall by means of expansion bolts.

[0029] Finally, we noticed that the bottom design of column 1 is also quite ingenious. The bottom of column 1 is connected to threaded column 4 through threads. This connection method not only ensures stability but also facilitates adjustment. A support plate 41 is fixed to the bottom end of threaded column 4. This support plate 41 not only increases the contact area with the ground, but also further improves the stability of the scaffolding. It is worth mentioning that a nut 42 is fixed on the support plate 41. This nut 42 is completely concentric with threaded column 4. This design can ensure that during the installation and adjustment process, threaded column 4 can always remain stable without deviation or shaking.

Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
