Description

Technical Field

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

[0002] Cantilever scaffolding is a type of construction facility that uses cantilevered structures extending outward from the edges of the building structure to support the external scaffolding. Its load is transferred to the main building through the cantilevered support structure.

[0003] A search revealed, for example, a cantilever scaffold provided by patent publication number CN222649389U, comprising: a main support, which is horizontally arranged and includes an insertable telescopic outer frame and a telescopic inner frame, one end of the main support being connected to the main building structure, and a scaffold support for the installed scaffold being provided on the telescopic outer frame and the telescopic inner frame respectively; and an auxiliary support, one end of which is connected to the main building structure, and the other end of which is connected to the other end of the main support to form a V-shaped structure, so that the main support can support cantilever scaffolds of different sizes and facilitates the replacement of scaffolds of different sizes.

[0004] Based on the above search and analysis of existing technologies, it has been found that most existing adjustable cantilever scaffolding systems, similar to those disclosed above, involve drilling holes in the building's exterior wall and then using bolts to fix the scaffolding supports to the wall. This method is not only labor-intensive but also detracts from the aesthetics of the building's exterior. Therefore, an adjustable cantilever scaffolding system is proposed to address these issues. Utility Model Content

[0005] The purpose of this application is to provide an adjustable cantilever scaffold to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: an adjustable cantilever scaffold, including a cantilever support and a scaffold body detachably installed on the cantilever support, wherein the cantilever support includes a longitudinal support, a transverse support, a diagonal brace support and a hanging frame;

[0007] The longitudinal supports, transverse supports, and diagonal braces are arranged in a right-angled triangle, and each pair of longitudinal supports, transverse supports, and diagonal braces is detachably connected by fixing bolts.

[0008] The bracket includes an L-shaped bracket and an adjustment assembly. The top of the L-shaped bracket is detachably connected to the top of the longitudinal support, and the adjustment assembly is connected to the L-shaped bracket.

[0009] The horizontal support has a sliding connection with mounting components.

[0010] As a further supplement to this solution, the adjustment assembly includes a positioning block, an adjusting screw, and a guide rod. The positioning block is located between the L-shaped hanger and the longitudinal support. The adjusting screw is horizontally threaded through the L-shaped hanger and rotatably connected to the positioning block. The guide rod is horizontally slidably passed through the L-shaped hanger and fixed to the positioning block.

[0011] As a further supplement to this solution, the top of the longitudinal support is detachably connected to an L-shaped plug by a fixing bolt. The top of the L-shaped bracket is fixed with a limit sleeve, which is vertically sleeved with the L-shaped plug.

[0012] As a further supplement to this plan, the longitudinal supports, transverse supports, diagonal braces, L-shaped hangers, and L-shaped inserts are all made of I-beams.

[0013] As a further supplement to this solution, multiple longitudinal supports and transverse supports are provided, with each longitudinal and transverse support arranged along its respective length direction, and adjacent longitudinal supports or transverse supports are detachably connected by fixing bolts.

[0014] As a further supplement to this solution, the mounting components include a sliding sleeve, a locking bolt, and a T-shaped mounting block. The sliding sleeve is slidably fitted onto the outside of the horizontal support. The locking bolt is threaded through the sliding sleeve and abuts against the horizontal support. The T-shaped mounting block is fixed to the upper end of the horizontal support, and a pre-drilled hole is provided on the T-shaped mounting block.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] 1. In this utility model, by setting up L-shaped hangers, L-shaped plugs and adjustment components, depending on whether there are suitable openings (such as windows or balconies) at the installation location on the building's exterior wall, the longitudinal support can be hung on the top of the L-shaped hanger using L-shaped hangers and L-shaped plugs, and the adjustment components can be used to prevent the longitudinal support from shaking. Alternatively, the L-shaped plugs can be removed from the longitudinal support, and holes can be drilled in the building's exterior wall using conventional methods and bolts can be used to fix the longitudinal support to the building's exterior wall, making the installation of this cantilevered scaffolding more flexible and convenient.

[0017] 2. In this utility model, by setting this installation component, there is no need to reserve installation holes on the horizontal support, thereby avoiding reducing the strength of the horizontal support. Moreover, the installation component can be flexibly adjusted according to the actual installation position of the scaffold body, making the installation more convenient and faster.

Detailed Implementation

[0024] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Reference Figure 1-4 An adjustable cantilever scaffold is shown, including a cantilever support and a scaffold body 12 that can be detachably installed on the cantilever support. The cantilever support includes a longitudinal support 1, a transverse support 2, a diagonal support 3, and a hanging bracket.

[0026] The longitudinal support 1, the transverse support 2, and the diagonal support 3 are arranged in a right-angled triangle. Each pair of the longitudinal support 1, the transverse support 2, and the diagonal support 3 is detachably connected by fixing bolts 10, which facilitates disassembly and replacement. The longitudinal support 1, the transverse support 2, the diagonal support 3, the L-shaped hanger 4, and the L-shaped plug 5 are all I-beams. There are multiple longitudinal supports 1 and transverse supports 2. Multiple longitudinal supports 1 and transverse supports 2 are arranged along their respective length directions. Adjacent longitudinal supports 1 or transverse supports 2 are detachably connected by fixing bolts 10, which facilitates adjustment of the overall length of the cantilever support according to actual installation needs.

[0027] The bracket includes an L-shaped bracket 4 and an adjustment assembly. The top of the L-shaped bracket 4 is detachably connected to the top of the longitudinal support 1. The adjustment assembly is connected to the L-shaped bracket 4. Specifically, the adjustment assembly includes a positioning block 6, an adjusting screw 7, and a guide rod 8. The positioning block 6 is located between the L-shaped bracket 4 and the longitudinal support 1. The adjusting screw 7 is horizontally threaded through the L-shaped bracket 4 and rotatably connected to the positioning block 6. The guide rod 8 is horizontally slidably passed through the L-shaped bracket 4 and fixed to the positioning block 6.

[0028] Regarding the detachable connection between the top of the L-shaped bracket 4 and the top of the longitudinal support 1, specifically, the top of the longitudinal support 1 is detachably connected to an L-shaped insert 5 via a fixing bolt 10. A limiting sleeve 9 is fixed to the top of the L-shaped bracket 4, and the limiting sleeve 9 and the L-shaped insert 5 are vertically connected. This cantilever support can be adjusted according to actual installation requirements. For installations on the exterior wall 13 with suitable openings (e.g., windows or balconies), the L-shaped bracket 4 can be hung at the opening of the exterior wall 13, and the longitudinal support 1 can be hung on the L-shaped bracket using the L-shaped insert 5. Tighten the adjusting screw 7 at the top of the hanger 4 to make the positioning block 6 abut against the inner surface of the building exterior wall 13, preventing the longitudinal support 1 from shaking. The adjusting screw 7, together with the positioning block 6, can be adapted to building exterior walls 13 of different thicknesses. If there is no suitable opening (such as a window or balcony) at the installation location of the building exterior wall 13, the L-shaped plug 5 can be removed from the longitudinal support 1. In this case, the conventional method can be used, that is, drilling holes in the building exterior wall 13 and using bolts to fix the longitudinal support 1 to the building exterior wall 13, making the installation of the cantilever scaffolding more flexible and convenient.

[0029] A mounting component is slidably connected to the horizontal support 2. Specifically, the mounting component includes a sliding sleeve 14, a locking bolt 15, and a T-shaped mounting block 16. The sliding sleeve 14 is slidably fitted onto the outside of the horizontal support 2. The locking bolt 15 is threaded through the sliding sleeve 14 and abuts against the horizontal support 2. The T-shaped mounting block 16 is fixed to the upper end of the horizontal support 2, and a pre-drilled hole 17 is provided on the T-shaped mounting block 16. By setting this mounting component, it is not necessary to pre-drill mounting holes on the horizontal support 2, thereby avoiding a reduction in the strength of the horizontal support 2. Moreover, the mounting component can be flexibly adjusted according to the actual installation position of the scaffold body 12, making installation more convenient and faster.

[0030] The working principle of this utility model is as follows: When there is a suitable opening (such as a window or balcony) at the installation position of the building exterior wall 13, the L-shaped bracket 4 can be used to hang at the opening of the building exterior wall 13, and the longitudinal support 1 can be hung on the top of the L-shaped bracket 4 using the L-shaped plug 5. Tighten the adjusting screw 7 so that the positioning block 6 is pressed against the inner surface of the building exterior wall 13 to prevent the longitudinal support 1 from shaking. The adjusting screw 7 and the positioning block 6 can be used to adapt to building exterior walls 13 of different thicknesses.

[0031] If there is no suitable opening (such as a window or balcony) at the installation location of the building exterior wall 13, the L-shaped plug 5 can be removed from the longitudinal support 1. In this case, the conventional method can be used, that is, drilling holes in the building exterior wall 13 and using bolts to fix the longitudinal support 1 to the building exterior wall 13.

[0032] When installing the scaffold body 12, the mounting components on the horizontal support 2 can be slid according to the actual installation position of the scaffold body 12 for the scaffold body 12 to be installed. After installation, tighten the locking bolts 15 to fix the scaffold body 12 and the horizontal support 2 relative to each other.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
