Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building engineering, concretely relates to a column embracing type overhanging platform for facade construction. BACKGROUND

[0002] In the traditional construction industry, the construction of building facades has always been a highly technical and challenging field. Three common and crucial technical means are basket construction, setting up external scaffolding, and using landing lifting machinery. Basket construction, as a common form of high-altitude work, provides a relatively stable construction environment for workers by suspending a basket on the outside of a building, allowing them to perform cleaning, maintenance, or decoration work. Setting up external scaffolding as another traditional construction method provides a temporary structure around the building to provide a work platform and support for workers. Using landing lifting machinery for facade construction, such lifting machinery usually includes lifting platforms, tower cranes, and construction elevators, which can quickly and accurately deliver workers and building materials to the construction site, greatly improving construction efficiency.

[0003] Traditional basket construction, setting up external scaffolding, and using landing lifting machinery have requirements for land and roof conditions, and the cost of handling high-altitude independent frame columns, corridor columns, or protruding structural columns is also relatively high. Basket construction has strict requirements for land and roof conditions, such as requiring stable support points and sufficient work space. Once encountering complex terrain or building structures, such as steep roofs, narrow corridors, or high-altitude independent frame columns, basket construction may not be sufficient, and even pose a safety hazard. For complex parts such as high-altitude independent frame columns, corridor columns, or protruding structural columns, the difficulty and cost of setting up external scaffolding increase linearly, often becoming a major burden on project budgets. The use of landing lifting machinery requires a certain operating environment, including a flat ground, stable support structure, and sufficient work space. Therefore, there is an urgent need for a structure that is not limited by land and roof conditions and does not require handling high-altitude independent frame columns, corridor columns, or protruding structural columns to conveniently provide workers with a work platform for facade construction.

[0074] Referring to Figure 1 and Figure 2 , the embodiment proposes a column type cantilever platform for facade construction, which comprises a support assembly 1, a platform assembly 3 and at least one auxiliary support assembly 2. Referring to Figure 3 , the support assembly 1 comprises a first cross rod 11, a second cross rod 12, a first longitudinal rod 13 and a second longitudinal rod 14, the first cross rod 11 and the second cross rod 12 are arranged along the transverse direction, the first longitudinal rod 13 and the second longitudinal rod 14 are arranged along the longitudinal direction, the first cross rod 11, the first longitudinal rod 13, the second cross rod 12 and the second longitudinal rod 14 are connected in sequence and form a frame structure which can abut the outer side wall of the outer column 7.

[0075] Referring to Figures 2-4The auxiliary support assembly 2 can be arranged at the upper end or the lower end of the first horizontal bar 11, and of course, in other embodiments, the auxiliary support assembly 2 can also be arranged at both the upper end and the lower end of the first horizontal bar 11 in order to enhance the support strength. The auxiliary support assembly 2 comprises a first connecting piece 21 and a second connecting piece 22. The first connecting piece 21 is connected with the second connecting piece 22 and embraces the outer column 7, that is, after the first connecting piece 21 is connected with the second connecting piece 22, a cavity is formed between the first connecting piece 21 and the second connecting piece 22, the inner diameter and the shape of the cavity are consistent with the outer diameter and the shape of the outer column 7 respectively, so that the inner side wall of the first connecting piece 21 and the inner side wall of the second connecting piece 22 can be completely fitted with the outer side wall of the outer column 7, and the connection strength between the column-embracing cantilever platform and the outer column 7 can be further enhanced. The first connecting piece 21 is connected with the first horizontal bar 11 and the second horizontal bar 12, and of course, in order to increase the connection strength, the second connecting piece 22 can also be connected with the first horizontal bar 11 and the second horizontal bar 12.

[0076] Referring to Figure 1 and Figure 3 , in order to facilitate the standing of the construction personnel, the column-embracing cantilever platform is provided with a platform assembly 3, and the platform assembly 3 comprises a platform plate 31, a first cantilever beam 32 and a second cantilever beam 33 which are connected with each other. The first cantilever beam 32 is connected with the second longitudinal bar 14, the second cantilever beam 33 is connected with the first horizontal bar 11, and the platform plate 31 is connected to the upper ends of the first cantilever beam 32 and the second cantilever beam 33. The platform plate 31 can be a metal plate, a wooden plate, a plastic plate or a composite plate made of multiple materials. The first cantilever beam 32 and the second cantilever beam 33 serve as the direct bearing structure of the platform plate 31, and the first cantilever beam 32 and the second cantilever beam 33 are not connected to the same component, so that the weight of the platform plate 31 and the construction personnel can be effectively dispersed, thereby enhancing the stability and safety of the entire column-embracing cantilever platform. Here, the number of the first cantilever beam 32 and the second cantilever beam 33 is not limited, referring to Figure 3 , the first cantilever beam 32 and the second cantilever beam 33 are arranged on both sides of the first horizontal bar 11, which can effectively increase the bearing area of the platform plate 31 and significantly improve the standing area and the operation safety of the construction personnel, thereby providing a strong guarantee for high-altitude operation.

[0077] The present embodiment can be applied to common cylindrical and cubic outer columns, and has wide applicability. Referring to Figure 5 (in order to show the contact between the support assembly and the outer column, Figure 5 the auxiliary support assembly is omitted in the figure), when the outer column 7 is cubic, the frame structure of the support assembly 1 can be completely fitted with the outer side wall of the outer column 7. Referring to Figure 2 , when the outer column 7 is cylindrical, the frame structure of the support assembly 1 can only abut against part of the outer side wall of the outer column 7. It is worth noting that the cavity enclosed by the first connecting piece 21 and the second connecting piece 22 after being connected can be Figure 4The cylindrical cavity shown in the figure can also be a cuboid cavity, so that the column-holding cantilever platform can be applied to cylindrical and cuboid outer columns, and the auxiliary support assembly 2 can be in close abutment with the outer column 7. The auxiliary support assembly 2 and the support assembly 1 generate friction or fastening force with the outer column 7, and the entire column-holding cantilever platform can be kept stable by means of the outer column 7, effectively ensuring the connection strength and overall stability of the column-holding cantilever platform and the outer column 7, providing a stable working platform, and effectively improving the construction efficiency and safety.

[0078] Since the column-holding cantilever platform uses the outer column as a support point to form a stable working space, the traditional construction platform often needs to be established on a stable ground or roof, and the column-holding cantilever platform breaks this limitation. The column-holding cantilever platform does not depend on the specific conditions of the land or roof, greatly expanding the adaptability of the working environment, so that it can be applied in various complex outer facade construction environments. Since in the outer facade construction of high-rise buildings or complex structures, obstacles such as high-altitude independent frame columns, corridor columns or protruding structural columns are often encountered, the column-holding cantilever platform can flexibly bypass these obstacles and directly work on the outer column, without the need for additional processing or modification of these obstacles, thereby saving time and cost and reducing construction risks.

[0079] The structural design of the embodiment is reasonable, simple and convenient to manufacture, and the installation and removal of the column-holding cantilever platform can be completed in the floor, which can be used repeatedly, and has good applicability to the outer facade decoration and decoration construction of existing reinforced concrete and steel outer columns.

[0080] 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 longitudinally and transversely telescopic to adapt to outer columns of different sizes. Referring to Figure 6 and Figure 7, the first longitudinal rod 13 comprises a first branch rod 131 and a first socketed branch rod 132, and the second longitudinal rod 14 comprises a second branch rod 141 and a second socketed branch rod 142. In order to realize longitudinal telescoping, the first socketed branch rod 132 is nested in the first branch rod 131, allowing the first socketed branch rod 132 to move freely inside the first branch rod 131 to adjust the distance between the two, and when the first socketed branch rod 132 is moved along the first branch rod 131 to a first preset position, the first socketed branch rod 132 is connected with the first branch rod 131, at which point the first preset position should satisfy that the maximum distance between the first branch rod 131 and the first socketed branch rod 132 is consistent with the longitudinal length of the outer column 7, i.e. the total length of the first longitudinal rod 13 is consistent with the longitudinal length of the outer column 7; the second branch rod 141 and the second socketed branch rod 142 are respectively connected with the first cross rod 11 and the second cross rod 12, and the second socketed branch rod 142 is nested in the second branch rod 141 and can be moved along the second branch rod 141 to a first preset position and then connected with the second branch rod 141. In order to realize transverse telescoping, the first branch rod 131 and the first socketed branch rod 132 can be moved along the first cross rod 11 to a second preset position and then connected with the first cross rod 11. The above-mentioned second preset position should satisfy that the distance between the first branch rod 131 and the first socketed branch rod 132 and the second branch rod 141 and the second socketed branch rod 142 is consistent with the transverse length of the outer column 7.

[0081] In one specific embodiment, referring to Figure 3 、 Figure 8 and Figure 9 , at least one side (which can be the upper surface or the lower surface or the inner side) of the first cross rod 11 and the second cross rod 12 is provided with a threaded hole 15, and the first branch rod 131 and the first socketed branch rod 132 are respectively provided with at least one connecting piece 16. When the first branch rod 131 and the first socketed branch rod 132 are moved along the first cross rod 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, thereby fixing the first branch rod 131 and the first socketed branch rod 132 with the first cross rod 11 and the second cross rod 12 respectively, not only providing a stable and reliable connection method, but also facilitating installation and disassembly, thereby providing strong support and protection for the column-holding cantilever platform.

[0082] In one specific embodiment, referring to Figure 3 、 Figure 8 and Figure 9The first longitudinal rod 13 further comprises a first fixing member 133. The first supporting rod 131 is provided with a first mounting hole 1311 at intervals. The first socket supporting rod 132 is provided with a second mounting hole 1321 matching the first mounting hole 1311 at intervals. When the first socket supporting rod 132 is moved along the first supporting rod 131 to the first preset position, the first fixing member 133 passes through the first mounting hole 1311 and the second mounting hole 1321, thereby firmly connecting the first supporting rod 131 and the first socket supporting rod 132 together. This connection not only ensures the stability of the relative position between the two, but also improves the carrying capacity of the entire first longitudinal rod 13, providing a more stable and adjustable support structure for the column-holding cantilever platform, further improving its overall performance and stability. Here, the first fixing member 133 can be a bolt, a pin or other components that can achieve fastening, the selection of which depends on the specific design requirements, material properties and required connection strength.

[0083] In one specific embodiment, referring to Figure 3 , Figure 6 and Figure 7 , the second longitudinal rod 14 further comprises a second fixing member (not shown in the figure). The second supporting rod 141 is provided with a first connecting hole 1411 at intervals. The second socket supporting rod 142 is provided with a second connecting hole 1421 matching the first connecting hole 1411 at intervals. When the second socket supporting rod 142 is moved along the second supporting 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 supporting rod 141 and the second socket supporting rod 142 together. This connection enhances the overall rigidity and carrying capacity of the second longitudinal rod 14, preventing deformation or loosening due to uneven stress, ensuring 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 that can achieve fastening, the selection of which depends on the specific design requirements, material properties and required connection strength.

[0084] In one specific embodiment, referring to Figure 10 (to show the contact relationship between the pulley assembly 6 and the outer column 7, Figure 10 ignore the auxiliary support assembly) and Figure 11, in order 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 further arranged. The pulley assembly 6 is connected to the side walls of the outer column 7 towards the first support rod 131 and the second support rod 141, and 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 stability 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, which can support the column-holding cantilever platform and the load thereon, and ensure that no dangerous situations such as overturning or falling occur during the movement. The support beam 4 is connected between the first cross rod 11 and the second cross rod 12, and the lifting assembly 5 is connected below the support beam 4. The lifting assembly 5 is a key component for controlling the lifting of the column-holding cantilever platform, and through the operation of the lifting assembly 5, the height of the entire column-holding cantilever platform can be adjusted to adapt to different working requirements, improving the flexibility and efficiency of the work. Through the synergistic effect 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 work.

[0085] In one embodiment, referring to Figure 11 , the pulley assembly 6 includes a pulley body 61 and ear plates 62 arranged on both sides of the pulley body 61. The ear plates 62 are connected to the side walls of the outer column 7 towards the first support rod 131 and the second support rod 141, providing stable support for the pulley body 61. The ear plates 62 should have sufficient rigidity and stability to withstand various forces and moments generated during the movement of the column-holding cantilever platform. The pulley body 61 is connected to the ear plates 62 on both sides by a pin shaft. Specifically, the 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 locking nuts, split pins, etc. to prevent the pin shaft from falling out. The pin shaft connection not only realizes reliable connection between the pulley body 61 and the ear plates 62, but also ensures that the pulley body 61 maintains a stable center of rotation during rolling, while helping to reduce friction and wear between the pulley body 61 and the ear plates 62, prolonging the service life. The pulley body 61 directly contacts and rolls along the outer column 7. Through the synergistic effect of the pulley body 61 and the ear plates 62, the column-holding cantilever platform is provided with stable and reliable mobility.

[0086] In one embodiment, referring to Figure 10The lifting assembly 5 comprises 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-holding 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 to provide a stable support point for the scissor lift 51. The driving mechanism 52 is the power source of the lifting assembly 5, and is connected with 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 hydraulic devices, electric push rods, pneumatic rods and other devices capable of lifting in the prior art. In use, the scissor lift 51 realizes lifting through the mutual interlacing and telescoping of multiple scissor arms (not shown in the figure). When the driving mechanism 52 is started, it will drive the movement of the scissor arms, so that the distance between the first support plate 53 and the second support plate 54 changes, thereby pushing the column-holding cantilever platform to rise or fall. The design of the scissor lift 51 enables the column-holding cantilever platform to remain stable and level during lifting, reducing the shaking and tilting caused by lifting. Through the cooperation 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-holding cantilever platform is realized, and the lifting efficiency, stability and safety of the column-holding cantilever platform are ensured.

[0087] In one embodiment, referring to Figure 2 and Figure 4 The auxiliary support assembly 2 further comprises a reinforcing rib 24 and a connecting plate 23 fixed to the first connecting piece 21. Taking the case where the connecting plate 23 is fixed to the first connecting piece 21 as an example, the connecting plate 23 is connected with the first cross bar 11 and the second cross bar 12, thereby stably connecting the first connecting piece 21 with the first cross bar 11 and the second cross bar 12. In order to ensure the stability of the connection, the connecting plate 23 can be integrally formed with the first connecting piece 21. The connecting plate 23 is provided with a reinforcing rib 24 connected to the connecting plate 23 and the first connecting piece 21, which can enhance the overall rigidity and carrying capacity, improve the ability to resist external loads and deformation, and thus ensure the stability and safety of the column-holding cantilever platform during use.

[0088] In one embodiment, referring to Figure 4 The inner side walls of the first connecting piece 21 and the second connecting piece 22 are provided with teeth or protrusions (not shown in the figure), so that the first connecting piece 21 and the second connecting piece 22 form a biting effect with the outer column, increase the contact area and friction, and thus prevent slipping or loosening under stress, so as to increase the overall stability and safety of the column-holding cantilever platform.

[0089] In one embodiment, referring to Figure 1The platform assembly 3 further comprises a safety guard rail 34 connected vertically to the outer periphery of the platform plate 31. By setting the guard rail, the construction personnel can be prevented from falling.
