[0051] In the embodiments of the present invention, a column-holding cantilever platform for facade construction is provided. Through the provided support component and auxiliary support component, the support component forms a frame structure that can abut against the outer side wall of the outer column, and the auxiliary support component can surround the outer column and closely abut against the outer column. The auxiliary support component and the support component generate frictional force or fastening force with the outer column.

[0069] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully communicated to those skilled in the art.

[0071] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0072] The inventor found that traditional construction methods such as using suspended baskets, erecting external scaffolding, and using landing lifting machinery have requirements for both land and roof conditions, and the treatment costs for high-altitude independent frame columns, corridor columns, or protruding structural columns are also relatively high. Specifically, the construction of suspended baskets has relatively strict requirements for land and roof conditions, such as stable support points and sufficient working space. Once encountering complex terrains or building structures, such as steep roofs, narrow corridors, or high-altitude independent frame columns, the construction of suspended baskets may be inadequate and even pose safety hazards. For complex parts such as high-altitude independent frame columns, corridor columns, or protruding structural columns, the difficulty and cost of erecting external scaffolding increase linearly, often becoming a major burden on the project budget. The method of using landing lifting machinery has certain requirements for the working environment, requiring a flat ground, a stable support structure, and sufficient working space.

[0073] To solve the above problems, through research and development, the inventor proposed a column-holding cantilever platform for exterior wall construction. By relying on the already constructed exterior columns, it is not restricted by land and roof conditions, and there is no need to deal with high-altitude independent frame columns, corridor columns or protruding structural columns.

[0074] Embodiment

[0075] Refer to Figure 1 and Figure 2 In this embodiment, a column-holding cantilever platform for exterior wall construction is proposed. The column-holding cantilever platform includes a support assembly 1, a platform assembly 3 and at least one auxiliary support assembly 2. Refer to Figure 3 As shown in the figure, the support assembly 1 includes a first cross bar 11, a second cross bar 12, a first longitudinal bar 13 and a second longitudinal bar 14. The first cross bar 11 and the second cross bar 12 are both arranged horizontally, the first longitudinal bar 13 and the second longitudinal bar 14 are both arranged vertically, and the first cross bar 11, the first longitudinal bar 13, the second cross bar 12 and the second longitudinal bar 14 are connected in sequence and enclose a frame structure that can abut against the outer side wall of the exterior column 7.

[0076] Refer to Figures 2 - 4 As shown in the figure, the auxiliary support assembly 2 can be arranged at the upper end or the lower end of the first cross bar 11. Of course, in other embodiments, in order to enhance the support strength, the auxiliary support assembly 2 can also be arranged at both the upper end and the lower end of the first cross bar 11. The auxiliary support assembly 2 includes a first connecting member 21 and a second connecting member 22. The first connecting member 21 is connected to the second connecting member 22 and surrounds the exterior column 7. That is, after the first connecting member 21 and the second connecting member 22 are connected, a cavity is formed between them. The inner diameter and shape of the cavity are respectively the same as the outer diameter and shape of the exterior column 7, so that the inner side walls of the first connecting member 21 and the second connecting member 22 can be completely attached to the outer side wall of the exterior column 7, which can further enhance the connection strength between the column-holding cantilever platform and the exterior column 7. The first connecting member 21 is connected to the first cross bar 11 and the second cross bar 12. Of course, in order to increase the connection strength, the second connecting member 22 can also be connected to the first cross bar 11 and the second cross bar 12.

[0077] Refer to Figure 1 and Figure 3, To facilitate the construction workers to stand, a platform component 3 is provided on the column-hugging cantilever platform. The platform component 3 includes a platform board 31, a first cantilever beam 32 and a second cantilever beam 33 which are connected to each other. The first cantilever beam 32 is connected to the second longitudinal rod 14, and the second cantilever beam 33 is connected to the first cross bar 11. The platform board 31 is connected to the upper ends of the first cantilever beam 32 and the second cantilever beam 33. The platform board 31 can be a metal plate, a wooden board, a plastic plate or a composite plate of multiple materials. The first cantilever beam 32 and the second cantilever beam 33 serve as the direct load-bearing structures of the platform board 31. The first cantilever beam 32 and the second cantilever beam 33 are not connected to the same component, which can effectively disperse the weight of the platform board 31 and the construction workers, thereby enhancing the stability and safety of the entire column-hugging cantilever platform. Here, the number of the first cantilever beam 32 and the second cantilever beam 33 is not limited. Refer to Figure 3 , the first cantilever beam 32 and the second cantilever beam 33 are provided on both sides of the first cross bar 11, which can effectively increase the bearing area of the platform board 31, significantly improve the standing area and operation safety of the construction workers, and provide a strong guarantee for high-altitude operations.

[0078] This embodiment can be applied to common cylindrical and cubic outer columns, with wide applicability. Refer to Figure 5 (In order to show the contact situation between the support component and the outer column, Figure 5 the auxiliary support component is omitted in Figure 2 . When the outer column 7 is cubic, the frame structure of the support component 1 can completely fit on the outer side wall of the outer column 7. Refer to Figure 4 . When the outer column 7 is cylindrical, the frame structure of the support component 1 can only abut against a part of the outer side wall of the outer column 7. It should be noted that the cavity formed after the first connecting piece 21 and the second connecting piece 22 are connected can be

[0079] Since the column-type cantilever platform uses the external columns as support points to form a stable working space, the traditional construction platform often needs to be built on a stable ground or roof. The column-type cantilever platform breaks this limitation. The column-type cantilever platform does not rely on the specific conditions of the land or roof, which greatly expands the adaptability of the working environment, allowing it to be used in various complex facade construction environments. Since obstacles such as high-altitude independent frame columns, corridor columns or protruding structural columns are often encountered in the facade construction of high-rise buildings or complex structures, the column-type cantilever platform can flexibly bypass these obstacles and work directly on the external columns without the need for additional processing or modification of these obstacles, thereby saving time and cost and reducing construction risks.

[0080] The structural design of this embodiment is reasonable, the structure is simple, and the production is convenient. The installation and removal of the column-embracing cantilever platform can be completed within the floor, and it can be used in rotation. It has good applicability to the facade decoration and renovation construction of existing reinforced concrete and steel structure exterior columns.

[0081] In a specific embodiment, in order to increase the flexibility and adaptability of the column-holding cantilever platform, the support assembly as a whole can be extended and retracted in the longitudinal and transverse directions to adapt to external columns of different sizes. Figure 6 and Figure 7 The first longitudinal rod 13 includes a first support rod 131 and a first socket support rod 132 , and the second longitudinal rod 14 includes a second support rod 141 and a second socket support rod 142 . In order to achieve longitudinal telescopic expansion, the first socket support rod 132 is nested in the first support rod 131, allowing the first socket support rod 132 to move freely inside the first support rod 131, thereby adjusting the distance between the two. When the first socket support rod 132 moves to the first preset position along the first support rod 131, the first socket support rod 132 is connected to the first support rod 131. Here, the first preset position should satisfy: the maximum distance between the first support rod 131 and the first socket support rod 132 is consistent with the longitudinal length of the outer column 7, that is, the total length of the first longitudinal rod 13 is consistent with the longitudinal length of the outer column 7; the second support rod 141 and the second socket support rod 142 are respectively connected to the first cross bar 11 and the second cross bar 12, the second socket support rod 142 is nested in the second support rod 141, and the second socket support rod 142 can be connected to the second support rod 141 after moving to the first preset position along the second support rod 141. In order to achieve lateral expansion and contraction, the first support rod 131 and the first socket support rod 132 can be moved along the first cross bar 11 to the second preset position and then connected to the first cross bar 11. The second preset position should satisfy: the spacing between the first support rod 131 and the first socket support rod 132 and the second support rod 141 and the second socket support rod 142 is consistent with the lateral length of the outer column 7.

[0082] In a specific embodiment, see Figure 3 , Figure 8 andFigure 9 , at least one side surface (this side surface can be the upper surface, lower surface or inner side surface) of the first cross bar 11 and the second cross bar 12 is provided with threaded holes 15 at intervals. The first support rod 131 and the first socket support rod 132 are respectively provided with at least one connecting piece 16. When the first support rod 131 and the first socket support rod 132 move along the first cross bar 11 to the second preset position, the connecting piece 16 will be aligned with the corresponding threaded hole 15, and the connecting piece 16 and the corresponding threaded hole 15 are threadedly connected, so as to fix the first support rod 131 and the first socket support rod 132 to the first cross bar 11 and the second cross bar 12 respectively. This not only provides a stable and reliable connection method, but also is convenient for installation and disassembly, providing strong support and guarantee for the column-holding cantilever platform.

[0083] In a specific embodiment, refer to Figure 3 , Figure 8 and Figure 9 , the first longitudinal rod 13 further includes a first fixing piece 133. The first support rod 131 is provided with first mounting holes 1311 at intervals, and the first socket support rod 132 is provided with second mounting holes 1321 matching the first mounting holes 1311 at intervals. When the first socket support rod 132 moves along the first support rod 131 to the first preset position, the first fixing piece 133 passes through the first mounting hole 1311 and the second mounting hole 1321, so as to firmly connect the first support rod 131 and the first socket support rod 132 together. This connection method not only ensures the relative position stability between the two, but also improves the bearing capacity of the entire first longitudinal rod 13, providing a more stable and adjustable support structure for the column-holding cantilever platform, and further enhancing its overall performance and stability. Here, the first fixing piece 133 can be a bolt, a pin or other components that can achieve fastening, and its selection depends on specific design requirements, material characteristics and required connection strength.

[0084] In a specific embodiment, refer to Figure 3 , Figure 6 and Figure 7, the second longitudinal rod 14 further includes a second fixing member (not shown in the figure). The first connecting holes 1411 are provided at intervals on the second support rod 141, and the second connecting holes 1421 matching the first connecting holes 1411 are provided at intervals on the second socket support rod 142. After the second socket support rod 142 moves along the second support rod 141 to the first preset position, the second fixing member passes through the first connecting hole 1411 and the second connecting hole 1421, thereby firmly connecting the second support rod 141 and the second socket support rod 142 together. This connection method enhances the overall rigidity and load-bearing capacity of the second longitudinal rod 14, prevents deformation or loosening caused by uneven stress, and ensures the stability and safety of the entire column-holding cantilever platform. Here, the second fixing member can be a bolt, a pin or other components capable of achieving fastening, and its selection depends on specific design requirements, material characteristics and required connection strength.

[0085] In a specific embodiment, refer to Figure 10 (To show the contact relationship between the pulley assembly 6 and the outer column 7, Figure 10 the auxiliary support assembly is ignored) and Figure 11 , to improve the liftability and mobility of the column-holding cantilever platform, a support beam 4, a lifting assembly 5 and a pulley assembly 6 are also provided. The pulley assembly 6 is connected to the side walls of the first support rod 131 and the second support rod 141 facing the outer column 7. The pulley assembly 6 can roll along the outer column 7, which can reduce the frictional resistance between the column-holding cantilever platform and the outer column 7 and ensure the smoothness and smoothness of the column-holding cantilever platform during the up and down movement; at the same time, the pulley assembly 6 also has a certain load-bearing capacity and can support the column-holding cantilever platform and its load thereon to ensure that no dangerous situations such as tipping or falling off will occur during the movement. The support beam 4 is connected between the first cross bar 11 and the second cross bar 12, and the lifting assembly 5 is connected below the support beam 4. The lifting assembly 5 is the key component for controlling the lifting of the column-holding cantilever platform. By operating the lifting assembly 5, the height of the entire column-holding cantilever platform can be adjusted to adapt to the working requirements at different heights, improving the flexibility and efficiency of the work. Through the coordinated action of the support beam 4, the lifting assembly 5 and the pulley assembly 6, the stability, liftability and mobility of the column-holding cantilever platform are realized, providing a safe, efficient and convenient solution for high-altitude operations.

[0086] In a specific embodiment, refer to Figure 11, the pulley assembly 6 includes a pulley body 61 and ear plates 62 provided on both sides of the pulley body 61. The ear plates 62 are connected to the side walls of the first support rod 131 and the second support rod 141 facing the outer column 7, providing stable support for the pulley body 61. The ear plates 62 should have sufficient rigidity and stability to withstand various forces and torques generated during the movement of the column-clamping cantilever platform. The pulley body 61 is pin-connected to the ear plates 62 on both sides. Specifically, a pin shaft (not shown in the figure) passes through the reserved holes (not shown in the figure) on the pulley body 61 and the ear plates 62, and is equipped with locking devices (not shown in the figure) such as lock nuts and split pins to prevent the pin shaft from falling off. The pin connection can not only achieve a reliable connection between the pulley body 61 and the ear plates 62, but also ensure that the pulley body 61 maintains a stable rotation center during the rolling process. At the same time, it helps to reduce the friction and wear between the pulley body 61 and the ear plates 62, and extends the service life; the pulley body 61 directly contacts the outer column 7 and rolls along the outer column 7. Through the coordinated action of the pulley body 61 and the ear plates 62, stable and reliable moving performance is provided for the column-clamping cantilever platform.

[0087] In a specific embodiment, refer to Figure 10 , the lifting assembly 5 includes a scissor lift 51, a driving mechanism 52, a first support plate 53 and a second support plate 54. The scissor lift 51 is connected between the first support plate 53 and the second support plate 54, and realizes the lifting of the column-clamping cantilever platform through its unique scissor structure. The first support plate 53 is connected below the support beam 4, and the second support plate 54 can be supported on the ground, providing a stable support point for the scissor lift 51. The driving mechanism 52 is the power source of the lifting assembly 5. The driving mechanism 52 is connected to the first support plate 53 and is responsible for providing the necessary driving force for the scissor lift 51. Here, the driving mechanism 52 can include devices such as hydraulic devices, electric push rods, and pneumatic rods in the prior art that can achieve lifting. During use, the scissor lift 51 realizes lifting through the interlacing and telescoping of multiple scissor arms (not marked in the figure). When the driving mechanism 52 is started, it will drive the movement of the scissor arms, causing the distance between the first support plate 53 and the second support plate 54 to change, thereby pushing the column-clamping cantilever platform up or down. The design of the scissor lift 51 enables the column-clamping cantilever platform to maintain horizontal stability during the lifting process, reducing the shaking and tilting caused by lifting. Through the coordinated action of the scissor lift 51, the driving mechanism 52, the first support plate 53 and the second support plate 54, the lifting function of the column-clamping cantilever platform is realized, and the lifting efficiency, stability and safety of the column-clamping cantilever platform are ensured.

[0088] In a specific embodiment, refer to Figure 2 and Figure 4, the auxiliary support assembly 2 further includes a reinforcing rib 24 and at least a connecting plate 23 fixed to the first connecting member 21. Taking the connecting plate 23 fixed to the first connecting member 21 as an example for illustration, the connecting plate 23 is connected to the first cross bar 11 and the second cross bar 12, thereby firmly connecting the first connecting member 21 with the first cross bar 11 and the second cross bar 12. To ensure the reliability of the connection, the connecting plate 23 and the first connecting member 21 can be integrally formed. The connecting plate 23 is provided with a reinforcing rib 24, and the reinforcing rib 24 is connected to the connecting plate 23 and the first connecting member 21, which can enhance the overall rigidity and load-bearing capacity, improve the ability to resist external loads and deformations, and thus ensure the stability and safety of the column-holding cantilever platform during use.

[0089] In a specific embodiment, referring to Figure 4 , the inner side walls of the first connecting member 21 and the second connecting member 22 are provided with tooth patterns or bumps (not shown in the figure), so that an engaging effect is formed between the first connecting member 21 and the second connecting member 22 and the outer column, increasing the contact area and friction force, thereby preventing slippage or loosening during stress application, so as to increase the overall stability and safety of the column-holding cantilever platform.

[0090] In a specific embodiment, referring to Figure 1 , the platform assembly 3 further includes a safety guardrail 34, and the safety guardrail 34 is vertically connected to the outer peripheral edge of the platform plate 31. By providing the guardrail, it is possible to prevent construction workers from falling.
