The rotating connection structure comprises a fixed connection disc, a rotating connection disc and a split rotating sleeve. The rotating connection disc rotates relative to the fixed connection disc to change the relative position of a first connection guide structure and a second connection guide structure, so that the connection limiting piece at the end of the horizontal rod can be connected with the horizontal rod and the vertical rod in different directions. The horizontal rod adopts a length adjustable structure, and the length after adjustment is fixed by a locking assembly. The angle support rod is connected between adjacent horizontal rods.

Description

Technical Field

[0001] This application relates to the field of scaffolding erection technology, and in particular to a rotating adjustable scaffolding and its erection method. Background Technology

[0002] Scaffolding is a commonly used temporary support and working platform in construction. It typically consists of uprights, horizontal bars, diagonal braces, and connecting nodes set on the uprights. In existing disc-lock, ring-lock, or other node-type scaffolding, the horizontal bars are usually connected to the uprights through connecting plates pre-installed on the uprights. The connecting holes or connection positions are distributed at fixed angles, so that adjacent horizontal bars are generally erected perpendicular to each other or in other predetermined directions to form a regular rectangular or square support system.

[0003] For building structures with regular planar outlines and upright spacing conforming to standard modules, the aforementioned scaffolding can meet basic erection requirements. However, during the construction of curved beams, inclined beams, irregularly shaped edge beams, parallelogram beams, and other irregular building structures, the boundary direction and dimensions of the structure to be supported often differ from the standard connection direction and standard member length of the scaffolding. Because the horizontal connection direction of existing connection nodes is relatively fixed, it is difficult to adjust the angle of the horizontal bars according to the actual outline of the structure to be supported. This easily leads to problems such as upright positions deviating from the target support position, horizontal bars failing to connect accurately, or large gaps existing between the support frame and the structure to be supported.

[0004] To accommodate the aforementioned irregular structure, construction sites typically compensate by adding standard couplers, adjusting the position of uprights, using non-standard length horizontal bars, or adding temporary connecting rods. These methods not only increase the variety of scaffolding components and the workload on site, but also make it difficult to standardize connection positions and force directions, easily leading to cluttered local member arrangements, uneven stress at nodes, and unclear support paths, thus affecting the overall stability of the scaffolding and construction safety. Furthermore, standard couplers require individual positioning and tightening by construction workers, resulting in low erection and dismantling efficiency, and the tightening quality is easily affected by manual operation.

[0005] Therefore, existing scaffolding has at least the following technical problems: fixed connection angles of connecting members at connection nodes, difficulty in adapting to irregular building structures, mismatch between the length of horizontal bars and the spacing of non-standard vertical bars, and low erection efficiency and insufficient stress stability of temporary connection methods used to adapt to irregular support areas.

[0006] Therefore, it is necessary to provide a rotating adjustable scaffold and an erection method to solve the above-mentioned problems existing in the prior art. Summary of the Invention

[0007] In view of the shortcomings of the prior art described above, the purpose of this application is to provide a rotating adjustable scaffold and an erection method to solve the aforementioned problems.

[0008] To achieve the above and other related objectives, a first aspect of this application provides a rotatable adjustable scaffold, comprising: multiple uprights; multiple horizontal bars, each horizontal bar having connecting limiting members at both ends; multiple rotatable connection structures, each rotatable connection structure comprising: a fixed connecting plate sleeved on the upright, the fixed connecting plate having a first connecting guide structure; a rotatable connecting plate rotatably connected to the fixed connecting plate, the rotatable connecting plate having a second connecting guide structure; a split rotatable sleeve comprising a first rotatable sleeve and a second rotatable sleeve coaxially arranged, the first rotatable sleeve and the second rotatable sleeve both being sleeved on the upright and respectively located at both ends of the fixed connecting plate, and respectively connected to the inner sidewalls of both ends of the rotatable connecting plate; wherein, when the rotatable connecting plate rotates relative to the fixed connecting plate, the relative position between the first connecting guide structure and the second connecting guide structure changes, and the connecting limiting members pass through the first connecting guide structure and / or the second connecting guide structure to connect the horizontal bar and the upright; and multiple corner braces, each corner brace having its two ends respectively connected to an adjacent horizontal bar.

[0009] In some embodiments of the first aspect of this application, the first connecting guide structure includes a closed first arc-shaped guide hole and two open first arc-shaped guide grooves arranged circumferentially along the fixed connecting disk, the two open first arc-shaped guide grooves respectively extending to the outer edge of the fixed connecting disk; the second connecting guide structure includes three closed second arc-shaped guide holes arranged circumferentially along the rotating connecting disk.

[0010] In some embodiments of the first aspect of this application, the fixed connecting plate includes an annular sleeve portion and a peripheral plate portion connected to the outside of the annular sleeve portion. The annular sleeve portion is sleeved on the upright, and the outer edge of the peripheral plate portion and the annular sleeve portion form the open first arc-shaped guide groove.

[0011] In some embodiments of the first aspect of this application, the inner circumferential side of the rotating connecting disc is provided with an annular limiting groove extending circumferentially thereon. The limiting groove includes two groove walls arranged opposite to each other along the axial direction of the split rotating sleeve and a groove bottom connecting the two groove walls. An opening is formed between the two groove walls and the groove bottom. The opening is engaged with the annular sleeve portion, and the outer edge of the peripheral disc portion is rotatably embedded in the limiting groove.

[0012] In some embodiments of the first aspect of this application, the connecting limiting member includes an arc-shaped pin and an arc-shaped pin limiting member. Both ends of the crossbar are provided with mounting through holes adapted to the arc-shaped pin. The arc-shaped pin limiting member is disposed in the mounting through hole to restrict the movement of the arc-shaped pin inserted into the mounting through hole.

[0013] In some embodiments of the first aspect of this application, the connecting limiting member further includes lugs disposed on both sides of the mounting through hole, a connecting rod connecting the two lugs, and an arc-shaped pin having a strip groove extending along its length direction. The connecting rod passes through the strip groove so that the arc-shaped pin rotates relative to the connecting rod along the strip groove.

[0014] In some embodiments of the first aspect of this application, the crossbar includes a fixed section, an adjusting section, and a locking assembly; the locking assembly includes a threaded pressure ring and a rotating fastening sleeve; the threaded pressure ring is fixedly connected to one end of the adjusting section, the outer circumferential surface of the threaded pressure ring is provided with an external thread, the inner circumferential surface is provided with an internal thread, and the peripheral wall of the threaded pressure ring is provided with a through slit; the rotating fastening sleeve is rotatably sleeved on the adjusting section and covers the outside of the threaded pressure ring, its inner circumferential surface includes an internal thread section and an inner conical surface section located on one axial side of the internal thread section, the inner diameter of the inner conical surface section gradually decreases in the direction away from the internal thread section, and the internal thread section and the threaded pressure ring are connected. The threaded ring engages with the external thread of the threaded compression ring; the outer surface of the end of the fixed rod section is provided with multiple annular threads, and the end of the fixed rod section passes through the threaded compression ring; when the rotating fastening sleeve rotates in the locking direction, the internal thread section drives the threaded compression ring to move axially through the external thread and enter the inner conical surface section, causing the threaded compression ring to contract radially, and lock it by engaging the annular thread of the fixed rod section through its internal thread, so as to fix the relative position of the crossbar adjusting section and the fixed rod section; when the rotating fastening sleeve rotates in the loosening direction, the internal thread section drives the threaded compression ring to move axially and exit the inner conical surface section, causing the threaded compression ring to expand radially, so as to loosen the fixed rod section.

[0015] In some embodiments of the first aspect of this application, a plurality of the rotary connection structures are provided at intervals along the axial direction on the same upright, and the plurality of rotary connection structures are respectively connected to the crossbars at corresponding heights.

[0016] In some embodiments of the first aspect of this application, the corner brace includes a horizontal corner brace and a vertical diagonal brace; the horizontal corner brace is connected between two horizontal bars at the same horizontal height; the vertical diagonal brace is connected between two horizontal bars at different heights.

[0017] To achieve the above and other related objectives, a second aspect of this application provides a method for erecting a rotatable adjustable scaffold. The method includes: determining the placement positions of each upright in the scaffold and the connection directions of horizontal bars between adjacent uprights based on the arrangement of the structure to be supported; fitting a fixed connecting plate onto the corresponding upright and installing a rotating connecting plate and a split-type rotating sleeve; rotating the rotating connecting plate so that a first connecting guide structure on the fixed connecting plate and a second connecting guide structure on the rotating connecting plate form corresponding horizontal bar connection positions; inserting a connecting limiting member at the end of the horizontal bar through the first connecting guide structure and / or the second connecting guide structure to connect the horizontal bars between adjacent uprights; adjusting the length of the horizontal bar according to the distance between adjacent uprights and fixing the length of the length-adjustable horizontal bar using a locking assembly; and connecting corner braces between the corresponding horizontal bars.

[0018] As described above, this application has the following beneficial effects:

[0019] This application utilizes a rotating connection structure on the uprights, comprising a fixed connecting plate, a rotating connecting plate, and a split rotating sleeve. This allows the rotating connecting plate to rotate relative to the fixed connecting plate. By changing the relative position between the first and second connecting guide structures, the connection direction between the horizontal bar and the uprights can be adjusted, overcoming the limitation of fixed connection angles in traditional scaffolding. This enables the scaffolding to adapt to rectangular, rhomboid, arc-shaped, and other irregularly shaped erection requirements. By setting an arc-shaped pin and its limiting structure, the connecting limiting component can be inserted through a combination of rotation and movement, maintaining its connection at the end of the horizontal bar. This improves the ease of horizontal bar assembly and disassembly and reduces the risk of component loss. By setting the horizontal bar as a length-adjustable structure and utilizing a rotating fastening sleeve, threaded pressure ring, and inner conical surface to achieve radial contraction locking, the horizontal bar can adapt to different upright spacings while ensuring connection reliability after adjustment. By setting horizontal corner braces and vertical diagonal braces between adjacent horizontal bars, the planar stability and overall resistance to lateral deformation of the scaffolding can be improved.

[0044] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and technical effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the concept of this application. It should be noted that, unless otherwise specified, the following embodiments and features in the embodiments can be combined with each other.

[0045] It should be noted that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the implementation conditions of this application. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the technical effects and objectives achieved by this application, should still fall within the scope of the technical content disclosed in this application.

[0046] The directional terms "upper," "lower," "inner," "outer," "horizontal," and "vertical" used in this manual are only for the purpose of describing the relative positional relationships between the components in conjunction with the accompanying drawings, and are not intended to limit the specific absolute orientation of the corresponding components in actual use. When the setting direction, viewing direction, or use state of the rotatable adjustable scaffold 100 changes, the corresponding directional relationships may change accordingly.

[0047] like Figure 1 As shown, this embodiment provides a rotatable scaffold 100, used to form a support frame in building construction, equipment installation, construction of irregular structures, construction of curved structures, or other platform erection scenarios requiring temporary work support. The rotatable scaffold 100 includes multiple uprights 10, multiple horizontal bars 20, multiple rotatable connection structures 30, and multiple corner braces 40.

[0048] The scaffold 10 consists of multiple uprights 10 perpendicular to the ground, forming the main vertical load-bearing components of the rotatable scaffold 100; multiple horizontal bars 20 are connected between adjacent uprights 10, forming lateral support and the load-bearing foundation for the work platform; a rotating connection structure 30 is disposed between the uprights 10 and the horizontal bars 20, enabling the connection between the horizontal bars 20 and the uprights 10, and allowing the horizontal bars 20 to change their connection direction relative to the uprights 10 within a predetermined range; and corner braces 40 are connected between adjacent horizontal bars 20, improving the overall stability of the rotatable scaffold 100.

[0049] Unlike traditional connecting disc structures that can only connect horizontal bars in a fixed, perpendicular direction, this embodiment uses a rotatable connecting structure 30 on the uprights 10, allowing the horizontal bars 20 to change their connection direction according to the shape and arrangement of the structure 200 to be supported. Furthermore, the adjustable length of the horizontal bars 20 adapts to different spacings between adjacent uprights 10, enabling the rotatable scaffolding 100 to be erected as a conventional rectangular structure, as well as a rhomboid, polygonal, arc-shaped, or irregularly shaped structure formed by a combination of various shapes.

[0050] like Figure 2 As shown, each rotary connection structure 30 includes a fixed connecting plate 31, a rotary connecting plate 32, and a split rotary sleeve 33.

[0051] The fixing plate 31 is sleeved and fixed to the corresponding upright 10, so that the fixing plate 31 remains fixed relative to the upright 10 during the erection and use of the scaffold. The fixing method between the fixing plate 31 and the upright 10 can be selected according to the design load-bearing capacity of the scaffold, the processing method, and the assembly and disassembly requirements, as long as it can limit the undesirable axial movement and circumferential rotation of the fixing plate 31 relative to the upright 10, including but not limited to welding, bonding, etc.

[0052] A first connecting guide structure 311 is provided on the fixed connecting plate 31. The first connecting guide structure 311 is used to cooperate with the connecting limiting member 21 at the end of the crossbar 20, and is used to define the area where the crossbar 20 can be connected during the rotation of the rotating connecting plate 32.

[0053] The rotating connecting plate 32 is disposed on the outer periphery of the fixed connecting plate 31 and is rotatably connected to the fixed connecting plate 31, so that the rotating connecting plate 32 can rotate relative to the fixed connecting plate 31 about the axis of the upright 10. The rotating connecting plate 32 is provided with a second connecting guide structure 321, which is used to cooperate with the first connecting guide structure 311 to form the connection position of the crossbar 20.

[0054] The split rotating sleeve 33 includes an upper rotating sleeve and a lower rotating sleeve arranged coaxially. The upper rotating sleeve 331 and the lower rotating sleeve 332 are both sleeved on the upright 10 and are located at both ends of the fixed connecting plate 31 along the axial direction of the upright 10.

[0055] Specifically, the upper rotating sleeve 331 is located on the upper side of the fixed connecting plate 31, and the lower rotating sleeve 332 is located on the lower side of the fixed connecting plate 31. The upper rotating sleeve 331 is connected to the inner wall of the upper end of the rotating connecting plate 32, and the lower rotating sleeve 332 is connected to the inner wall of the lower end of the rotating connecting plate 32, thereby forming a rotating assembly that can rotate together around the upright 10.

[0056] By configuring the rotating sleeve as an axially separate upper rotating sleeve 331 and lower rotating sleeve 332, the rotating connecting plate 32 can be connected and limited from the upper and lower sides of the fixed connecting plate 31, respectively. On the one hand, this improves the coaxial stability of the rotating connecting plate 32 when rotating around the upright 10, reducing tilting or swaying of the rotating connecting plate 32; on the other hand, the split structure facilitates the assembly between the rotating connecting plate 32 and the fixed connecting plate 31, allowing the fixed connecting plate 31 to remain fixed while the rotating connecting plate 32 can rotate independently.

[0057] When adjusting the connection direction of the crossbar 20, the construction worker can rotate at least one of the upper rotating sleeve 331, the lower rotating sleeve 332, or the rotating connecting plate 32. Since the upper rotating sleeve 331, the rotating connecting plate 32, and the lower rotating sleeve 332 are interconnected, the rotational action can be transmitted to the rotating connecting plate 32, causing the rotating connecting plate 32 to rotate relative to the fixed connecting plate 31 about the axis of the upright 10.

[0058] As the rotating connecting plate 32 rotates relative to the fixed connecting plate 31, the relative positions between the first connecting guide structure 311 and the second connecting guide structure 321 change, thereby creating crossbar connection positions at different circumferential locations on the rotating connecting structure 30, through which the connecting limiting member 21 can pass. Construction personnel can rotate the rotating connecting plate 32 to the corresponding position according to the extension direction of the crossbar 20 to be connected, and then connect the crossbar 20 to the rotating connecting structure 30 via the connecting limiting member 21.

[0059] In one specific implementation, such as Figure 3 As shown, the first connecting guide structure 311 includes a closed first arc-shaped guide hole 313 and two open first arc-shaped guide grooves 314.

[0060] A closed first arc-shaped guide hole 313 penetrates through the fixed connecting plate 31 and extends circumferentially along the fixed connecting plate 31. Both ends of the closed first arc-shaped guide hole 313 are located inside the plate body of the fixed connecting plate 31, thus forming a circumferentially closed arc-shaped through hole structure.

[0061] Two open-type first arc-shaped guide grooves 314 are spaced apart along the circumference of the fixed connecting plate 31 and extend to the outer edge of the fixed connecting plate 31, respectively. In addition to having a guide area extending along the circumference, the open-type first arc-shaped guide grooves 314 also have an opening communicating with the outside of the fixed connecting plate 31, so that the end of the crossbar 20 or the connecting limiting member 21 can enter the corresponding connection area from the radial outside of the fixed connecting plate 31.

[0062] This embodiment provides a closed first arc-shaped guide hole 313 and two open first arc-shaped guide grooves 314, enabling the fixed connecting plate 31 to simultaneously have a closed limiting area and an open access area. The closed first arc-shaped guide hole 313 can form a relatively complete circumferential limiting for the connecting limiting member 21, while the open first arc-shaped guide grooves 314 can reduce assembly interference when the end of the crossbar 20 enters the rotating connecting structure 30, which is beneficial for the crossbar 20 to connect to the upright 10 from different directions.

[0063] The fixed connecting plate 31 includes an annular sleeve portion 315 and an outer peripheral plate portion 316. The annular sleeve portion 315 is located on the inner circumference of the fixed connecting plate 31 and is sleeved on the upright 10. The outer peripheral plate portion 316 is connected to the outer side of the annular sleeve portion 315 and extends radially outward along the upright 10.

[0064] A closed first arc-shaped guide hole 313 is provided on the outer disk portion 316. Two open first arc-shaped guide grooves 314 are provided at different circumferential positions on the outer disk portion 316. Each open first arc-shaped guide groove 314 extends from the inside of the outer disk portion 316 to the outer edge of the outer disk portion 316, thereby forming a groove on the outer edge of the outer disk portion 316.

[0065] In other words, the open-type first arc-shaped guide groove 314 can be understood as an arc-shaped notch structure formed on the outer disk portion 316. The side of the groove near the annular sleeve portion 315 is defined by the inner region of the outer disk portion 316, while the side away from the annular sleeve portion 315 communicates with the external space. The connecting limiting member 21 can enter the open-type first arc-shaped guide groove 314 from the outside of the outer disk portion 316 through the opening.

[0066] like Figure 4 As shown, the second connecting guide structure 321 includes three closed second arc-shaped guide holes 322. The three closed second arc-shaped guide holes 322 are spaced apart circumferentially along the rotating connecting disk 32 and extend circumferentially along the rotating connecting disk 32, respectively.

[0067] As the rotating connecting disc 32 rotates, the three closed second arc-shaped guide holes 322 synchronously change position relative to the closed first arc-shaped guide hole 313 and the two open first arc-shaped guide grooves 314. Thus, different closed second arc-shaped guide holes 322 can selectively form overlapping areas, connected areas, or connecting areas through which the connecting limiting member 21 can pass with either the closed first arc-shaped guide hole 313 or the open first arc-shaped guide groove 314.

[0068] Both the first connecting guide structure 311 and the second connecting guide structure 321 adopt an arc-shaped structure, rather than just a circular hole structure with a size basically the same as the connecting pin, so that the connecting limiting member 21 has a certain position adjustment margin in the corresponding arc-shaped area. Therefore, the rotating connecting plate 32 does not have to cooperate with the fixed connecting plate 31 only at a single discrete angle, but can form multiple usable connection positions within the corresponding arc-shaped guide range, which is beneficial for continuous or graded adjustment of the connection direction of the crossbar 20. In addition, the arc length of the first arc-shaped guide groove 314 along its own bending path is greater than the arc length of the second arc-shaped guide hole 322 along its own bending path, ensuring that the combination of the two can adapt to different extension directions of the crossbar 20.

[0069] In one connection state, the closed second arc-shaped guide hole 322 and the closed first arc-shaped guide hole 313 at least partially overlap, and the connecting limiting member 21 passes through the closed second arc-shaped guide hole 322 and the closed first arc-shaped guide hole 313 in sequence, thereby connecting the crossbar 20 to the connection position formed by the fixed connecting plate 31 and the rotating connecting plate 32.

[0070] In another connection state, the closed second arc-shaped guide hole 322 and the open first arc-shaped guide groove 314 at least partially overlap, and the end of the crossbar 20 can enter through the opening of the open first arc-shaped guide groove 314. The connecting limit member 21 passes through the closed second arc-shaped guide hole 322 and the open first arc-shaped guide groove 314 to complete the connection between the crossbar 20 and the rotary connection structure 30.

[0071] In other feasible assembly configurations, depending on the specific structure of the end of the crossbar 20 and the insertion path of the connecting limiting member 21, the connecting limiting member 21 can also be inserted into the corresponding connection area defined by the first connecting guide structure 311 or the second connecting guide structure 321. As long as the connection direction of the crossbar 20 can be adjusted by changing the relative position between the first connecting guide structure 311 and the second connecting guide structure 321, the connection direction of the crossbar 20 can be achieved.

[0072] like Figure 5As shown, the inner circumferential side of the rotating connecting disk 32 is provided with an annular limiting groove extending along its circumference. The annular limiting groove includes two groove walls 323 arranged opposite to each other along the axial direction of the split rotating sleeve 33 and a groove bottom 324 connecting the two groove walls 323.

[0073] Two groove walls 323 extend from the axial sides of the groove bottom 324 toward the fixed connecting plate 31, and the two groove walls 323 and the groove bottom 324 together define a limiting space to accommodate the outer edge of the outer plate portion 316. An opening of an annular limiting groove is formed on the side of the two groove walls 323 away from the groove bottom 324, and the opening faces the annular sleeve portion 315.

[0074] During assembly, the rotating connecting plate 32 is sleeved on the outer periphery of the fixed connecting plate 31, and the opening of the annular limiting groove is engaged with the area where the annular sleeve portion 315 is located. The outer edge of the outer plate portion 316 is rotatably embedded in the annular limiting groove. The outer edge of the outer plate portion 316 can slide relative to the rotating connecting plate 32 along the circumference of the annular limiting groove, thereby allowing the rotating connecting plate 32 to rotate relative to the fixed connecting plate 31.

[0075] Two groove walls 323 are located on opposite axial sides of the outer disk portion 316, providing axial restraint to limit excessive axial movement of the rotating connecting disk 32 relative to the fixed connecting disk 31. The groove bottom 324 is located radially outside the outer disk portion 316, limiting the radial position between the rotating connecting disk 32 and the fixed connecting disk 31. This improves the assembly stability between the two without affecting the circumferential rotation of the rotating connecting disk 32.

[0076] The upper rotating sleeve 331 and the lower rotating sleeve 332 are respectively connected to the upper and lower ends of the rotating connecting plate 32 and are sleeved on the upright 10, so that the rotating connecting plate 32 can rotate about the upright 10 as the central axis. The fixed connecting plate 31, the rotating connecting plate 32 and the split rotating sleeve 33 together form the main body of the rotating connecting structure 30.

[0077] When the crossbar 20 is subjected to a vertical load or a horizontal force, the load at the end of the crossbar 20 can be transmitted to the fixed connecting plate 31 and the rotating connecting plate 32 through the connecting limiting member 21, and then transmitted to the upright 10 by the fixed connecting plate 31. The annular limiting groove covering and limiting the outer plate portion 316 can reduce the possibility of the rotating connecting plate 32 detaching from the fixed connecting plate 31 under load.

[0078] like Figure 6 As shown, each end of the crossbar 20 is provided with a connecting limiting member 21, so that the two ends of the crossbar 20 can be connected to adjacent rotary connection structures 30 respectively. The connecting limiting member 21 includes an arc-shaped pin and an arc-shaped pin limiting member for limiting the movement of the arc-shaped pin.

[0079] Both ends of the crossbar 20 are provided with mounting through holes 201 adapted to the arc-shaped pin. The mounting through holes 201 are used to accommodate the arc-shaped pin and provide space for the arc-shaped pin to move between the retracted state and the inserted state.

[0080] The arc-shaped pin is arc-shaped in general, and its bending shape is adapted to the arc-shaped extension direction of the first connecting guide structure 311 and the second connecting guide structure 321. Compared with the straight pin, the arc-shaped pin can enter the corresponding arc-shaped guide hole or arc-shaped guide groove by a combination of rotation and movement when the space at the end of the crossbar 20 is limited, thereby reducing the possibility of interference between the end of the crossbar 20 and the fixed connecting plate 31 and the rotating connecting plate 32.

[0081] Lugs 202 are provided on both sides of the mounting through hole 201, the two lugs 202 are arranged opposite each other, and a connecting rod 203 is connected between the two lugs 202. A strip groove 211 extending along its length is opened on the arc-shaped pin, and the connecting rod 203 passes through the strip groove 211.

[0082] The connecting rod 203 and the strip groove 211 cooperate to limit the movement of the arc-shaped pin. On the one hand, the arc-shaped pin can rotate around the connecting rod 203, thereby changing the orientation of the arc-shaped pin relative to the end of the crossbar 20; on the other hand, since the strip groove 211 extends along the length of the arc-shaped pin, the connecting rod 203 can move relative to it within the strip groove 211, so that the arc-shaped pin can extend or retract a certain distance relative to the connecting rod 203 while rotating.

[0083] The limiting structure formed by the lug 202, the connecting rod 203, and the slot 211 can serve as a specific implementation of the arc-shaped pin limiting component. Since the connecting rod 203 always passes through the slot 211, even if the arc-shaped pin is not inserted into the first connecting guide structure 311 and the second connecting guide structure 321, the arc-shaped pin remains connected to the end of the crossbar 20 and is not easily completely separated from the crossbar 20, thereby reducing the possibility of the arc-shaped pin detaching during scaffolding disassembly, assembly, or transportation.

[0084] Before the crossbar 20 is connected to the rotary connection structure 30, the arc-shaped pin can be in the retracted state. In the retracted state, the main part of the arc-shaped pin is located near the end of the crossbar 20, preventing the arc-shaped pin from extending excessively and hindering the movement of the crossbar 20.

[0085] When connecting the crossbar 20, first move the end of the crossbar 20 to the corresponding connection position formed by the fixed connecting plate 31 and the rotating connecting plate 32, so that the mounting through hole 201 corresponds to the passable area of ​​the first connecting guide structure 311 and the second connecting guide structure 321. Then, operate the arc-shaped pin to rotate around the connecting rod 203, and make the connecting rod 203 move relative to each other along the strip groove 211.

[0086] Under the combined action of rotation and relative movement, the insertion end of the arc-shaped pin gradually changes its orientation and enters the connection area formed by the first connecting guide structure 311 and the second connecting guide structure 321. After the arc-shaped pin continues to move, its arc-shaped body passes through the corresponding arc-shaped guide hole or arc-shaped guide groove, so that the end of the crossbar 20 is limited by the rotating connecting structure 30.

[0087] Because the slot 211 provides the arc-shaped pin with a margin of movement relative to the connecting rod 203, the arc-shaped pin does not need to perform a simple circular motion around a completely fixed rotation center, but can adapt to the positions of the first connecting guide structure 311 and the second connecting guide structure 321. Therefore, even if there is a certain angle between the crossbar 20 and the rotating connecting plate 32, the insertion of the arc-shaped pin can be completed relatively smoothly.

[0088] When it is necessary to disassemble the crossbar 20, the arc pin is operated in the reverse direction, causing the arc pin to exit along the first connecting guide structure 311 and the second connecting guide structure 321. After the arc pin is exited, the connecting rod 203 still passes through the strip groove 211, and the arc pin remains connected to the end of the crossbar 20. Construction personnel do not need to store the arc pin as an independent part separately.

[0089] like Figure 7 As shown, in order to accommodate different spacing between adjacent uprights 10, the crossbar 20 adopts an adjustable length structure. Specifically, the crossbar 20 includes a fixed section 204, a crossbar adjustment section 205, and a locking assembly 206.

[0090] The fixed rod segment 204 and the crossbar adjusting segment 205 are arranged along the length direction of the crossbar 20. At least a portion of the fixed rod segment 204 can be inserted into the crossbar adjusting segment 205 or cooperate with the locking component 206 provided at the end of the crossbar adjusting segment 205. By changing the length of the fixed rod segment 204 inserted into the crossbar adjusting segment 205, the overall length of the crossbar 20 can be changed.

[0091] The locking assembly 206 includes a threaded pressure ring 2061 and a rotating fastening sleeve 2062. The threaded pressure ring 2061 is fixedly connected to one end of the crossbar adjusting section 205. The outer circumferential surface of the threaded pressure ring 2061 is provided with external threads, and the inner circumferential surface of the threaded pressure ring 2061 is provided with internal threads.

[0092] A through slit is provided on the peripheral wall of the threaded pressure ring 2061. The slit extends through the peripheral wall of the threaded pressure ring 2061 along the axial direction, so that the threaded pressure ring 2061 can contract toward its central axis when subjected to radial compressive force, and expand radially outward after the radial compressive force is reduced or released.

[0093] The rotating fastening sleeve 2062 is rotatably sleeved on the crossbar adjusting section 205 and covers the outside of the threaded pressure ring 2061. The inner circumferential surface of the rotating fastening sleeve 2062 includes an internal thread section and an internal conical surface section, with the internal conical surface section located on the axial side of the internal thread section.

[0094] The internal thread section engages with the external thread on the outer circumferential surface of the threaded pressure ring 2061. When the rotating fastening sleeve 2062 rotates relative to the threaded pressure ring 2061, the thread engagement between the internal thread section and the external thread converts the rotation of the rotating fastening sleeve 2062 into axial relative movement between the threaded pressure ring 2061 and the rotating fastening sleeve 2062.

[0095] The inner diameter of the inner conical section gradually decreases in the direction away from the internal thread section, that is, the inner conical section forms a tapered clamping space that gradually narrows axially. The threaded clamping ring 2061 can enter or exit the inner conical section under the drive of the rotating fastening sleeve 2062.

[0096] The outer surface of the end of the fixed rod segment 204 is provided with multiple annular threads, and the end of the fixed rod segment 204 passes through the threaded pressure ring 2061. During the length adjustment of the crossbar 20, the fixed rod segment 204 can move axially relative to the threaded pressure ring 2061 and the crossbar adjusting segment 205.

[0097] When it is necessary to lock the crossbar 20, rotate the fastening sleeve 2062 in the locking direction. The internal thread section of the fastening sleeve 2062 drives the threaded pressure ring 2061 to move axially through the external thread of the threaded pressure ring 2061, so that the threaded pressure ring 2061 gradually enters the inner conical surface section.

[0098] As the threaded pressure ring 2061 enters the inner conical section, the inner conical section applies a gradually increasing radial compressive force to the threaded pressure ring 2061. Under the action of the slit, the threaded pressure ring 2061 can undergo radial contraction, causing the internal thread on the inner circumferential surface of the threaded pressure ring 2061 to press against the multi-turn annular thread on the outer surface of the fixed rod section 204.

[0099] After the internal thread of the threaded pressure ring 2061 engages with the annular thread of the fixed rod section 204, the threaded pressure ring 2061 restricts the fixed rod section 204 from moving axially relative to the crossbar adjustment section 205, thereby fixing the current length of the crossbar 20.

[0100] When the length of the crossbar 20 needs to be readjusted, rotate the fastening sleeve 2062 in the loosening direction. The internal thread section of the fastening sleeve 2062 drives the threaded pressure ring 2061 to move axially in the opposite direction, causing the threaded pressure ring 2061 to gradually exit the inner conical section.

[0101] After the threaded pressure ring 2061 exits the inner conical section, the radial compressive force it experiences decreases. Because the threaded pressure ring 2061 has a through-slit, it can expand radially, causing its internal thread to disengage from or reduce the engagement with the annular thread on the fixed rod section 204. At this time, the fixed rod section 204 can move axially relative to the crossbar adjusting section 205 to readjust the length of the crossbar 20.

[0102] Using the aforementioned locking assembly 206, it is not necessary to completely remove the fixed rod section 204 from the crossbar adjusting section 205, nor is it necessary to pre-set a single pin hole on the fixed rod section 204. Construction personnel can continuously adjust the relative position of the fixed rod section 204 and the crossbar adjusting section 205 according to the actual distance between adjacent uprights 10, and then complete the locking by rotating the fastening sleeve 2062.

[0103] The multi-turn annular thread engages with the internal thread of the threaded pressure ring 2061, improving the axial limiting capability between the fixed rod section 204 and the crossbar adjusting section 205. The inner conical section converts the axial action of the rotating fastening sleeve 2062 into a radial clamping action on the threaded pressure ring 2061, thereby improving the locking reliability.

[0104] like Figure 1 and Figure 8 As shown, multiple rotary connection structures 30 can be installed at intervals along the axial direction on the same upright 10. Each rotary connection structure 30 corresponds to a different erection height of the scaffolding and is connected to a horizontal bar 20 of the corresponding height.

[0105] For example, rotating connection structures 30 can be installed at the lower, middle, and upper parts of the uprights 10 to form multi-layered lateral connections between adjacent uprights 10. Multiple horizontal bars 20 located at the same horizontal height form horizontal support layers of corresponding heights, and horizontal support layers of different heights are connected by uprights 10 to form a three-dimensional scaffolding structure.

[0106] Multiple rotating connection structures 30 on the same upright 10 can be adjusted according to the actual extension direction of the corresponding horizontal bar 20. That is, rotating connection discs 32 located at different heights on the same upright 10 do not need to maintain the same rotation angle, but can correspond to different horizontal bar connection directions.

[0107] Therefore, when the structure to be supported 200 has different outer contours at different heights, the crossbars 20 at each height can be adjusted to match the shape of the corresponding position of the structure to be supported 200 by adjusting the rotating connection structures 30 at different heights. For example, when the lower outer contour of the structure to be supported 200 is larger and the upper part gradually tapers, the crossbars 20 at different heights can form support frames of different sizes or angles.

[0108] The corner brace 40 includes a horizontal corner brace 41 and a vertical diagonal brace 42.

[0109] A horizontal brace 41 connects two crossbars 20 at the same horizontal level, used to limit undesirable relative rotation or in-plane deformation between adjacent crossbars 20 within the same horizontal support layer. The horizontal brace 41 can connect to the included angle region formed by adjacent crossbars 20, thereby forming a triangular stable structure together with the corresponding two crossbars 20.

[0110] It should be noted that the rotary connection structure 30 in this application is used to adjust the connection direction of the crossbars. After the angle adjustment is completed, the connection relationship between the corresponding crossbars is maintained by the horizontal corner braces 41 set between adjacent crossbars. Therefore, this application does not need to set an additional angle locking structure in the rotary connection structure 30, and each rotary connection structure 30 corresponds to at least one horizontal corner brace 41.

[0111] The vertical diagonal brace 42 connects two horizontal bars 20 located at different heights to limit the relative displacement between the horizontal bars 20 at different heights and improve the anti-tilting and anti-lateral deformation capacity of the rotatable adjustable scaffold 100 in the vertical plane.

[0112] Since the horizontal bars 20 in the rotatable adjustable scaffold 100 can be arranged in rectangular, rhomboid, arc, or other irregular shapes, the length and connection direction of the corner braces 40 can be selected according to the distance and angle between the corresponding horizontal bars 20. The horizontal corner braces 41 and the vertical diagonal braces 42 can be used individually or in combination in the same scaffold structure.

[0113] like Figure 9 As shown, when the rotatable adjustable scaffolding 100 is in its normal rectangular erection state, multiple uprights 10 are arranged in a rectangular or approximately rectangular array. Adjacent horizontal bars 20 are approximately perpendicular to each other, and multiple horizontal bars 20 form a rectangular frame.

[0114] In the rectangular erected state, rotate the rotating connecting disks 32 in each rotating connecting structure 30 to align the connection positions of each horizontal bar with the side lines of the rectangular frame. Then, connect the two ends of the horizontal bar 20 to the rotating connecting structures 30 on the adjacent vertical bars 10.

[0115] When the actual distance between adjacent uprights 10 is inconsistent with the initial length of the crossbar 20, the locking assembly 206 is loosened, and the fixed rod section 204 moves relative to the crossbar adjustment section 205 until the length of the crossbar 20 matches the distance between adjacent uprights 10. Then, the rotating fastening sleeve 2062 is rotated to lock the crossbar 20.

[0116] like Figure 10As shown, when the rotatable adjustable scaffolding 100 is in a diamond-shaped erection state, adjacent horizontal bars 20 form a non-right angle, and multiple horizontal bars 20 form a diamond-shaped frame or a parallelogram frame.

[0117] When adjusting from a rectangular erection state to a rhombus erection state, the rotating connecting discs 32 on each upright 10 can be rotated according to the target included angle of the rhombus frame, so that the second connecting guide structure 321 moves to the corresponding position relative to the first connecting guide structure 311.

[0118] Since both the first connecting guide structure 311 and the second connecting guide structure 321 include arc-shaped guide areas, the rotating connecting plate 32 can still form a connection position for the arc-shaped pin to pass through after rotation. The end of the crossbar 20 can be connected to the upright 10 in a non-perpendicular direction, without needing to remove the fixed connecting plate 31 from the upright 10 or replace it with a connecting plate of other specifications.

[0119] In a diamond-shaped erection configuration, the spacing between adjacent uprights 10 in different directions may change compared to a rectangular erection configuration. Therefore, the lengths of the horizontal bars 20 can be adjusted simultaneously to adapt each horizontal bar 20 to the actual distance between its corresponding uprights 10. After adjusting the direction and length, the adjacent horizontal bars 20 are then reinforced using corner braces 40.

[0120] like Figure 11 As shown, when the rotatable adjustable scaffolding 100 is in an arc-shaped erection state, multiple uprights 10 are arranged at intervals along the arc-shaped boundary of the structure to be supported 200, and adjacent horizontal bars 20 are connected sequentially between adjacent uprights 10, forming multiple continuous broken lines. The extension direction of each horizontal bar 20 changes segment by segment, so that multiple horizontal bars 20 together approach or surround the arc-shaped contour of the structure to be supported 200.

[0121] In the arc-shaped arrangement, the rotating connecting discs 32 in each rotating connecting structure 30 can have different rotation angles. For example, along the arc-shaped arrangement direction, the rotation angles of adjacent rotating connecting discs 32 gradually change, causing the crossbars 20 connected to them to extend tangentially or approximately tangentially along the arc.

[0122] Meanwhile, the spacing between adjacent uprights 10 can be set according to the curvature of the arc profile, construction space, and support requirements. By adjusting the relative positions of the fixed section 204 and the adjusting section 205 of the crossbars 20, each crossbar 20 can have the same or different lengths to accommodate the connection distances at different positions in the arc arrangement.

[0123] For the support structure 200 with varying curvature, the rotating connecting disc 32 at different positions can be rotated with different amounts, and the crossbar 20 can be adjusted with different lengths, thereby forming a scaffold profile with curvature varying with position. Therefore, this embodiment is not limited to forming a circular arc-shaped scaffold; it can also form an elliptical arc, a wave-shaped, a combination of folded arcs, or other irregular curved scaffolds.

[0124] The following describes the erection method of the rotating adjustable scaffolding 100 in conjunction with the above structure.

[0125] First, based on the layout, outer contour, and working space of the structure 200 to be supported, determine the location of each upright 10 in the scaffolding, and determine the target connection direction of the horizontal bars 20 between adjacent uprights 10. When determining the location of the uprights 10, the boundary shape of the structure 200 to be supported and the working space required by the scaffolding can be considered simultaneously.

[0126] Subsequently, corresponding rotary connection structures 30 are installed on each upright 10. Specifically, a fixed connecting plate 31 is sleeved and fixed to the upright 10, so that the first connecting guide structure 311 is at a predetermined height; a rotary connecting plate 32 is placed on the outer periphery of the fixed connecting plate 31, so that the outer edge of the outer plate portion 316 is embedded in the annular limiting groove formed by the groove wall 323 and the groove bottom 324; then the upper rotary sleeve 331 and the lower rotary sleeve 332 are respectively placed on the upper and lower sides of the fixed connecting plate 31 and connected to the rotary connecting plate 32.

[0127] After the installation of the rotary connection structure 30 is completed, the rotary connection disk 32 is rotated according to the target connection direction of the corresponding crossbar 20, so that the first connection guide structure 311 on the fixed connection disk 31 and the second connection guide structure 321 on the rotary connection disk 32 form the corresponding crossbar connection position.

[0128] During rotation, the positional relationship between the closed second arc-shaped guide hole 322 and the closed first arc-shaped guide hole 313 or the open first arc-shaped guide groove 314 can be observed. When the corresponding arc-shaped guide area forms a connecting area through which the connecting limiting member 21 can pass, the rotation of the rotating connecting disc 32 is stopped.

[0129] Subsequently, the end of the crossbar 20 is moved to the corresponding crossbar connection position. For the connection position corresponding to the open first arc-shaped guide groove 314, the end of the crossbar 20 can enter through the outer slot of the open first arc-shaped guide groove 314 to reduce interference between the end of the crossbar 20 and the outer disk 316 during installation.

[0130] After the end of the crossbar 20 is in place, the arc-shaped pin is rotated around the connecting rod 203, causing the connecting rod 203 to move relative to the connecting rod 203 along the strip groove 211, so that the arc-shaped pin passes through the connection area formed by the first connecting guide structure 311 and the second connecting guide structure 321. After the arc-shaped pin has passed through, the end of the crossbar 20 is restricted to the rotating connecting structure 30.

[0131] In the same manner, the other end of the crossbar 20 is connected to the rotary connection structure 30 on the adjacent upright 10. Thus, a transverse connection is formed between the adjacent uprights 10.

[0132] When the length of the crossbar 20 is inconsistent with the actual distance between the adjacent uprights 10, rotate the fastening sleeve 2062 in the loosening direction to make the threaded pressure ring 2061 exit the inner conical section and expand radially. Then, move the fixed rod section 204 or the crossbar adjusting section 205 to adjust their relative positions until the crossbar 20 reaches the required length.

[0133] After the length of the crossbar 20 is adjusted, the fastening sleeve 2062 is rotated in the locking direction to make the threaded pressure ring 2061 enter the inner conical section and contract radially, thereby making the internal thread of the threaded pressure ring 2061 engage with the annular thread on the fixed rod section 204 to fix the length of the crossbar 20.

[0134] After connecting all horizontal bars 20 at the same height in sequence, horizontal corner braces 41 are installed between adjacent horizontal bars 20 to improve the planar stability of the corresponding horizontal support layer. Vertical diagonal braces 42 are installed between horizontal bars 20 at different heights to improve the overall lateral stability of the scaffolding.

[0135] For scaffolding with multiple support layers of varying heights, multiple rotating connection structures 30 can be installed sequentially along the axial direction of the uprights 10, and the horizontal bars 20 and corner braces 40 at each height can be connected separately. The horizontal bars 20 at different heights can use the same connection direction and length, or they can be adjusted according to the different heights and outer contours of the structure 200 to be supported.

[0136] When it is necessary to change the erection form of the scaffolding, the corresponding corner brace 40 can be removed first, and then the arc pin can be removed from the first connecting guide structure 311 and the second connecting guide structure 321. Rotate the rotating connecting plate 32 according to the new horizontal bar connection direction, and adjust the length of the horizontal bar 20 according to the new vertical bar spacing. Then reinsert the arc pin and install the corner brace 40.

[0137] Therefore, the rotatable adjustable scaffolding 100 in this embodiment does not require a complete replacement of the fixed connecting plate 31 or a large number of replacements of crossbars 20 of different lengths, and can be adjusted between rectangular erection state, diamond erection state and arc erection state.

[0138] In this embodiment, the connection direction of the horizontal bar 20 is changed by the relative rotation of the fixed connecting plate 31 and the rotating connecting plate 32, the length of the horizontal bar 20 is changed by the relative movement of the fixed bar segment 204 and the horizontal bar adjusting segment 205, and the structural stability of the scaffold after adjustment is improved by the horizontal angle brace 41 and the vertical diagonal brace 42, so that the scaffold can adapt to the structure 200 to be supported with different contours, different angles and different upright spacing.

[0139] Meanwhile, the first connecting guide structure 311 and the second connecting guide structure 321 adopt an arc-shaped guide structure, which allows for circumferential adjustment of the connection position; the split-type rotating sleeve 33 connects to the rotating connecting disk 32 from both ends of the fixed connecting disk 31, which helps to maintain the rotational stability of the rotating connecting disk 32; the arc-shaped pin is movably connected to the connecting rod 203 through the strip groove 211, which can be inserted in a combination of rotation and movement, and can maintain the connection at the end of the crossbar 20; the locking assembly 206 uses the inner conical section to drive the slotted threaded pressure ring 2061 to retract radially, so as to achieve reliable locking of the crossbar 20 after adjustment.

[0140] In summary, this embodiment can improve the adjustability of the scaffold connection direction and erection outline while ensuring that the uprights 10, horizontal bars 20 and corner braces 40 form a stable support system. It reduces the problem of needing to configure a large number of special components due to fixed connection angles or mismatched horizontal bar lengths during the construction of irregular structures, and is conducive to improving the versatility and reusability of scaffold components.

[0141] The above embodiments are merely illustrative of the principles and technical effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
