Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, and more specifically, to an adjustable cantilever scaffolding. Background Technology

[0002] In the construction of high-rise buildings, cantilevered scaffolding serves as the main supporting structure for the exterior facade construction, undertaking multiple functions such as a work platform for construction workers, material storage, and transportation channels.

[0003] Traditional cantilever scaffolding typically involves directly cantilevering the scaffolding to the outside of the building. While this design meets basic construction needs, it presents significant safety hazards during assembly and disassembly. Specifically, because the cantilever scaffolding is located outside the building, assembly and disassembly operations not only need to be carried out at height but also face multiple adverse factors such as wind and unstable support surfaces, greatly increasing the difficulty and risk of the work. Therefore, we have made an improvement by proposing an adjustable cantilever scaffolding system. Utility Model Content

[0005] In order to achieve the above-mentioned objectives, this utility model provides an adjustable cantilever scaffold to improve the aforementioned problems.

[0006] The application is as follows:

[0007] An adjustable cantilever scaffold includes two first I-beams, each with a support plate on its upper part. Rollers are installed on both sides of the bottom of each support plate, and the outer surfaces of the rollers are slidably connected to the first I-beams. A cantilever scaffold assembly is provided between the tops of the two support plates.

[0018] In the scheme of this application:

[0019] To address the issue of low safety during assembly and disassembly of existing cantilever scaffolding, which is typically suspended directly on the outside of a building, this application utilizes a first I-beam and rollers to support a support plate.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] For an example, please refer to... Figures 1-3 An adjustable cantilever scaffold includes two first I-beams 1, each with a support plate 2 on top. Rollers 201 are installed on both sides of the bottom of each support plate 2, with the outer surface of the rollers 201 slidably connected to the first I-beams 1. A cantilever scaffold assembly is positioned between the tops of the two support plates 2. The first I-beams 1 and the rollers 201 support the support plates 2, which in turn support the scaffold assembly. The support plates 2 can move horizontally above the first I-beams 1, allowing the scaffold assembly to be moved to a relatively safe position inside the building during assembly and disassembly, effectively reducing the risks of working at height and ensuring the safety of construction workers.

[0030] Furthermore, the first I-beam 1 includes a lower flange and an upper flange, with a web between the lower flange and the upper flange. The outer surface of the roller 201 is slidably connected to the top of the lower flange, so that the lower flange can support the roller 201, while the upper flange can limit the roller 201 to prevent the roller 201 from separating from the first I-beam 1.

[0031] Furthermore, such as Figure 1 and Figure 3 As shown, the cantilever scaffolding assembly includes four vertical pipes 202, which are welded to the top of two support plates 2 respectively. Several horizontal pipes 203 are connected between the four vertical pipes 202 by scaffolding couplers. The scaffolding couplers are existing structures and will not be described in detail in this application.

[0032] Furthermore, such as Figure 1 , Figure 3 and Figure 4 As shown, support pipes 206 are installed on both support plates 2, and several working platforms 204 are arranged between the two support pipes 206. Hooks 205 are fixedly connected to both ends of the working platform 204. The two hooks 205 are respectively suspended on the outer surface of the two support pipes 206. The working platform 204 can be supported by the cooperation of the support pipes 206 and the hooks 205.

[0033] Furthermore, a fastener is provided between the first I-beam 1 and the support plate 2. The fastener is used to fix the position of the support plate 2 to prevent the support plate 2 from moving during use and to improve the stability of the support plate 2 during use.

[0034] Furthermore, such as Figure 1 and Figure 2 As shown, the fastener includes several threaded holes 104 provided on the first I-beam 1. A fixing bolt 4 is connected between the support plate 2 and the threaded holes 104. The connection between the fixing bolt 4 and the threaded holes 104 limits the support plate 2. After removing the fixing bolt 4, the limitation on the support plate 2 can be released, and the support plate 2 can be moved to the inside of the building.

[0035] Furthermore, such as Figure 1 and Figure 2 As shown, a second stop 105 is welded to one side of the top of each of the two first I-beams 1. The second stop 105 is used to limit the support plate 2. The second stop 105 is located on the outermost side, so that when the support plate 2 moves to the outermost side, it is blocked by the second stop 105 and cannot continue to move to the outermost side, which is safer.

[0036] Furthermore, such as Figure 1 and Figure 2 As shown, two first stops 102 are welded to the top of the first I-beam 1, and a clamping plate 101 is placed between the two first stops 102. The clamping plate 101 is used to connect to the building body through pre-embedded bolts to fix the clamping plate 101. A gap is left between the bottom of the support plate 2 and the top of the first I-beam 1, and the gap is greater than the thickness of the first stops 102. This setting avoids the first stops 102 from affecting the movement of the support plate 2.

[0037] Furthermore, a reinforcing member is provided between the bottoms of the two first I-beams 1, which can improve the firmness between the two first I-beams 1.

[0038] Furthermore, such as Figure 1 and Figure 2 As shown, the reinforcement includes a second I-beam 3 welded between the bottoms of the two first I-beams 1. A connecting plate 301 is welded to the top of the second I-beam 3. The connecting plate 301 is used to connect to the building body by pre-embedded bolts, so as to fix the second I-beam 3 by the connecting plate 301, thereby fixing the position of the first I-beam 1 and improving the stability of the first I-beam 1.

[0039] For ease of understanding, this application uses A to represent the building body, and it is marked in the figure. The building body has pre-embedded bolts at the corresponding positions. The clamping plate 101 and the connecting plate 301 are fixed by the pre-embedded bolts and nuts. The support plate 2 is pushed towards the second stop 105. When the support plate 2 contacts the second stop 105, the movement of the support plate 2 stops. Then the fixing bolt 4 is connected to the threaded hole 104. After unscrewing the fixing bolt 4, the support plate 2 is pulled towards the clamping plate 101 to move the support plate 2 to the inside of the building, which facilitates disassembly and assembly.
