Support apparatus and method for mounting and dismounting support apparatus

Abstract

The present disclosure relates to the technical field of support construction, and provides a support apparatus and a method for mounting and dismounting a support apparatus. The support apparatus comprises a support assembly and a moving assembly. The moving assembly is mounted at the bottom of the support assembly, and the moving assembly comprises a moving member, a support member, and a connecting structure. The moving member abuts against an upper side of the support member and forms an inclined-surface fit with the support member. The moving member is configured to move along an inclined surface between the moving member and the support member, so as to reduce the height of the top of the support assembly above the ground. The connecting structure is detachably connected between the moving member and the support member and is configured to restrict movement of the moving member relative to the support member. In the support apparatus, by means of the inclined-surface fit between the moving member and the support member, the height of the top of the support assembly above the ground can be reduced after construction of a construction section is completed, thereby separating the support assembly from the construction section, facilitating the removal of the support assembly from below the construction section for subsequent dismounting, avoiding having construction workers throw rods down from high places to clear the rods from the construction site, and effectively reducing construction risks.

Description

Support device and its installation and dismantling methods

[0001] Cross-reference to related applications

[0002] This disclosure claims priority to Chinese Patent Application No. 2024115972599, filed on November 11, 2024, entitled “Support Device and Method for Installing / Removing Support Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of scaffolding construction technology, and in particular to a scaffolding device and a method for installing and dismantling the scaffolding device. Background Technology

[0004] During the erection of existing scaffolding, the horizontal and vertical members need to be manually connected and fixed from bottom to top until the top of the scaffolding contacts the area to be constructed. Conversely, when the construction is completed and the scaffolding needs to be dismantled, workers must first climb to the top of the scaffolding and then dismantle each member sequentially from top to bottom.

[0005] In the actual dismantling of scaffolding, construction workers often throw dismantled components at heights to prevent them from piling up around the scaffolding and encroaching on the construction site, which can easily cause accidents. Summary of the Invention

[0006] The purpose of this disclosure is to provide a support device and a method for installing and dismantling the support device, in order to alleviate the technical problems that exist in the process of dismantling scaffolding. When construction workers dismantle the poles at high altitudes, in order to prevent the poles from piling up around the scaffolding and encroaching on the construction site, they usually throw the dismantled poles far away, which is very likely to cause accidents.

[0007] This disclosure provides a support device, including a support assembly and a movable assembly;

[0008] The movable component is mounted at the bottom of the support assembly, and the movable component includes a movable part, a support part, and a connecting structure.

[0009] The movable member abuts against the top of the support member and engages with the support member at an angle. The movable member is configured to move along the angle between itself and the support member to reduce the ground clearance of the top of the support assembly.

[0010] The connection structure is detachably connected between the movable member and the support member, and is configured to restrict the movement of the movable member relative to the support member.

[0011] In an optional embodiment, both the bottom of the movable member and the top of the support member are provided with inclined surfaces, and the inclined angle of the bottom inclined surface of the movable member and the inclined angle of the top inclined surface of the support member are the same relative to the same horizontal plane.

[0012] In an alternative embodiment, a pulley is rotatably mounted on the movable member, the pulley being configured to roll on the support member as the movable member moves along the inclined plane.

[0013] In an optional embodiment, the top of the support member is provided with a groove, and the pulley is located in the groove and is able to roll in the groove.

[0014] In an optional embodiment, the bottom of the movable component is provided with a mounting groove, and the pulley is rotatably mounted in the mounting groove.

[0015] In an optional embodiment, the connection structure includes an annular snap and a wedge-shaped member;

[0016] The annular buckle is sleeved on the outside of the mutually abutting movable member and the supporting member; the wedge-shaped member fills the gap between the side wall of the movable member, the side wall of the supporting member and the buckle to restrict the movement of the movable member relative to the supporting member.

[0017] In an optional embodiment, the connection structure includes a connecting bolt and a connecting nut;

[0018] Both the movable component and the support component are provided with through holes that are compatible with the connecting bolt. The connecting bolt passes through the through holes on the movable component and the support component and is threadedly connected to the connecting nut. One of the bolt head of the connecting bolt and the connecting nut abuts against the outside of the side wall of the movable component, and the other abuts against the outside of the side wall of the support component.

[0019] In an optional embodiment, the support assembly includes multiple support groups, which are stacked and connected from bottom to top, and each support group includes multiple support modules that are distributed and connected in pairs along the horizontal direction.

[0020] In the plurality of bracket groups, the movable component is mounted on the bottom of each bracket module in the bottom bracket group.

[0021] In an optional implementation, the support module includes a folding frame and a limiting rod;

[0022] The folding frame includes multiple hinge rods that are hinged together to enable the folding frame to be folded and unfolded; the limiting rod is configured to connect between the hinge rods of the folding frame after the folding frame is unfolded, so as to restrict the folding frame from folding.

[0023] This disclosure provides a method for installing and removing a support device, using the support device as described in any of the foregoing embodiments, including:

[0024] Move both the bracket assembly with the movable component at the bottom and the support component to the area to be constructed, and place the movable component against the top of the support component, while ensuring that the movable component and the support component are in a beveled fit.

[0025] The connecting structure is connected between the movable member and the support member to restrict the movement of the movable member relative to the support member;

[0026] Construction is carried out on the top of the support assembly at the area to be constructed. After construction is completed, the connecting structure is disassembled.

[0027] The movable member is moved along the inclined plane between itself and the support member to reduce the ground clearance of the top of the support assembly;

[0028] Pull the moving component horizontally to remove the support assembly from below the construction site.

[0029] The scaffolding device disclosed herein includes a scaffolding assembly and a movable assembly. The movable assembly is mounted on the bottom of the scaffolding assembly. The movable assembly includes a movable member, a support member, and a connecting structure. The movable member abuts against the top of the support member and engages with the support member at an angle. The movable member is configured to move along the angle between itself and the support member to reduce the ground clearance of the top of the scaffolding assembly. The connecting structure is detachably connected between the movable member and the support member and is configured to restrict the movement of the movable member relative to the support member. The scaffolding device disclosed herein can be used as scaffolding. Correspondingly, the scaffolding assembly can be a scaffolding structure formed by connecting horizontal, vertical, and diagonal members. Before construction on beams or other high-altitude areas, the scaffolding assembly can be assembled away from the construction area, and the movable member can be installed at the bottom of the scaffolding assembly. Then, both the scaffolding assembly with the movable member at the bottom and the support member are moved to below the construction area. The movable member is then abutted against the top of the support member, with the movable member engaging with the support member at an angle. Finally, the connecting structure can be connected between the moving part and the supporting part. This connection structure secures the moving part and the supporting part, effectively ensuring the stability of the moving component's support for the support assembly, and thus ensuring the structural stability of the support assembly. After the construction of the crossbeams and other parts on the top of the support assembly is completed, the support device can be removed from below the construction area. Specifically, the connecting structure can be disassembled first, and then the moving part can be driven to move along the inclined plane between it and the supporting part. As the moving part moves along the inclined plane on the supporting part, it can lower the entire support assembly, reducing the height of the top of the support assembly from the ground. At this point, the top of the support assembly separates from the construction area, facilitating the removal of the entire support assembly from the ground. After the support assembly with the moving part installed at the bottom is removed from below the construction area, it can be disassembled from top to bottom. Since the support assembly is now far from the construction area, construction workers do not need to worry about disassembled parts occupying the construction site, and therefore do not need to throw disassembled parts far away, effectively reducing the risk of objects being thrown from heights.

[0030] Compared with the prior art, the support device provided in this disclosure can ensure the stability of the support assembly through the connection structure. After the construction of the construction site is completed using the support assembly, the height of the top of the support assembly off the ground can be reduced by moving the movable part at the inclined surface between it and the support member. This allows the support assembly to be separated from the construction site, making it easier to move the entire support assembly away from below the construction site and disassemble it elsewhere. This avoids construction workers throwing poles from high altitudes due to poles encroaching on the construction site, thereby effectively reducing construction risks.

[0031] The method for installing and dismantling the support device disclosed herein utilizes the aforementioned support device and includes: moving both the support assembly with a movable component mounted on its bottom and the support component to below the area to be constructed, and placing the movable component abutting against the top of the support component, while simultaneously creating an inclined fit between the movable component and the support component; connecting the movable component and the support component with a connecting structure to restrict the movement of the movable component relative to the support component; performing construction on the area to be constructed at the top of the support assembly, and disassembling the connecting structure after construction is completed; moving the movable component along the inclined plane between it and the support component to reduce the ground clearance of the top of the support assembly; and pulling the movable component horizontally to remove the support assembly from below the construction area. Since this method for installing and dismantling the support device utilizes the aforementioned support device, it possesses the same beneficial effects as the aforementioned support device.

Detailed Implementation

[0055] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. The components of the embodiments of this disclosure described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0056] Therefore, the following detailed description of the embodiments of this disclosure provided in the accompanying drawings is not intended to limit the scope of the claimed disclosure, but merely to illustrate selected embodiments of the disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0057] The following detailed description of some embodiments of this disclosure is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0058] Example:

[0059] As shown in Figures 1-5, the support device provided in this embodiment includes a support assembly 1 and a moving assembly 2. The moving assembly 2 is installed at the bottom of the support assembly 1. As shown in Figures 4 and 5, the moving assembly 2 includes a moving member 20, a support member 21, and a connecting structure 22. The moving member 20 abuts against the upper part of the support member 21 and is inclined to engage with the support member 21. The moving member 20 is configured to move along the inclined surface between it and the support member 21 to reduce the height of the top of the support assembly 1 from the ground. The connecting structure 22 is detachably connected between the moving member 20 and the support member 21 and is configured to restrict the movement of the moving member 20 relative to the support member 21.

[0060] The support device provided in this embodiment can be used as scaffolding. Correspondingly, as shown in Figures 1, 2, and 3, the support assembly 1 can be a scaffolding structure formed by connecting horizontal bars, vertical bars, and diagonal bars. Before constructing on beams or other high-altitude areas, the support assembly 1 can be assembled away from the construction site, and a movable component 20 can be installed at the bottom of the support assembly 1. Then, the support assembly 1 with the movable component 20 installed at the bottom and the support component 21 are moved to below the construction site. As shown in Figures 4 and 5, the movable component 20 is placed against the top of the support component 21, with the movable component 20 and the support component 21 forming an inclined fit. Finally, a connecting structure 22 can be connected between the movable component 20 and the support component 21. At this time, the connecting structure 22 can achieve a connection and fixation between the movable component 20 and the support component 21, effectively ensuring the support stability of the support assembly 1 by the movable component 2, thereby ensuring the structural stability of the support assembly 1.

[0061] After the construction of the crossbeam and other parts on the top of the support assembly 1 is completed, the support device can be moved away from below the construction site using the vehicle 3 shown in Figure 1. Specifically, the connecting structure 22 can be disassembled first, and then the moving part 20 can be driven to move on the inclined plane between it and the support part 21. After the moving part 20 moves along the inclined plane on the support part 21, the moving part 20 can drive the support assembly 1 to descend as a whole, thereby reducing the height of the top of the support assembly 1 from the ground. At this time, the top of the support assembly 1 is separated from the construction site, making it easy to move the support assembly 1 as a whole away from the ground.

[0062] After the support assembly 1 with the movable part 20 installed at the bottom is moved away from the construction site by the pull rope structure of the vehicle 3 and the rear of the vehicle 3 shown in Figure 1, the support assembly 1 can be disassembled from top to bottom. Since the support assembly 1 is far away from the construction site, that is, the support assembly 1 is far away from the construction site, the construction personnel do not need to worry about the disassembled parts of the support assembly 1 occupying the construction site, and therefore do not need to throw the disassembled parts far away, effectively reducing the risk of objects being thrown from high altitudes.

[0063] The support device provided in this embodiment can ensure the stability of the support assembly 1 through the connecting structure 22. After the construction of the construction site is completed using the support assembly 1, the moving part 20 can be used to move at the inclined surface between it and the support part 21 to reduce the height of the top of the support assembly 1 from the ground, thereby separating the support assembly 1 from the construction site. This makes it easier to move the entire support assembly 1 away from below the construction site and disassemble the support assembly 1 elsewhere. This avoids construction workers throwing poles from high altitudes due to the poles encroaching on the construction site, thereby effectively reducing construction risks.

[0064] The inclined surface fit between the movable part 20 and the support part 21 means that at least one of the bottom of the movable part 20 and the top of the support part 21 is provided with an inclined surface 23. As long as the inclined surface 23 can reduce the ground height of the top of the bracket assembly 1 after the movable part 20 moves relative to the support part 21, it is acceptable.

[0065] To improve the contact stability between the moving part 20 and the support part 21, as shown in Figures 4 and 5, in this embodiment, the bottom of the moving part 20 and the top of the support part 21 are preferably provided with inclined surfaces 23, and the bottom inclined surface 23 of the moving part 20 and the top inclined surface 23 of the support part 21 have the same inclination angle relative to the same horizontal plane.

[0066] As shown in Figures 4 and 5, a pulley 200 is rotatably mounted on the movable member 20, and the pulley 200 is configured to roll on the support member 21 when the movable member 20 moves along the inclined plane.

[0067] When the moving part 20 moves along the inclined plane on the support 21, the pulley 200 rolls on the inclined plane, thereby converting the sliding friction between the moving part 20 and the support 21 into rolling friction, effectively reducing the resistance of the moving part 20 during movement, and thus improving the efficiency of the support device.

[0068] Optionally, as shown in Figures 4 and 5, the top of the support member 21 may be provided with a groove 210, and the pulley 200 is located in the groove 210 and can roll in the groove 210.

[0069] The groove 210 not only allows space for the pulley 200, preventing the pulley 200 from affecting the inclined surface fit between the moving part 20 and the support 21, but also limits the movement of the pulley 200, thereby improving the stability of the moving part 20 during its movement.

[0070] In this embodiment, as shown in FIG5, the pulley 200 can be rotatably mounted on both sides of the movable member 20 via a pivot. In order for the support member 21 to support the pulley 200, the width of the support member 21 must be greater than the width of the movable member 20. Correspondingly, the groove 210 is provided between the projection edge of the movable member 20 on the top of the support member 21 and the top edge of the support member 21.

[0071] Alternatively, the width of the support member 21 can be equal to the width of the movable member 20. In this case, to prevent the pulley 200 from affecting the inclined surface fit between the movable member 20 and the support member 21, as shown in Figure 4, the bottom of the movable member 20 is provided with an installation groove, and the pulley 200 is rotatably installed in the installation groove.

[0072] The mounting slot is configured to provide installation space for the pulley 200 and to protect the pulley 200 from interference with its rotation process by external objects.

[0073] In this embodiment, the connecting structure 22 can use fasteners such as locating pins and rivets.

[0074] Alternatively, as shown in Figure 4, the connecting structure 22 may include an annular buckle 220 and a wedge 221; the annular buckle 220 is sleeved on the outside of the mutually abutting movable member 20 and support member 21; the wedge 221 fills the gap between the side wall of the movable member 20, the side wall of the support member 21 and the buckle, so as to restrict the movement of the movable member 20 relative to the support member 21.

[0075] Among them, the wedge-shaped part 221 is in the shape of a triangular prism or triangular pyramid, and the perimeter of the ring buckle 220 needs to be greater than the perimeter of the moving part 20 and the support part 21 after they abut against each other.

[0076] When it is necessary to restrict the movement of the movable member 20 relative to the support member 21 using the connecting structure 22, the annular buckle 220 can be first fitted onto the abutting movable member 20 and support member 21. At this time, there is a gap between the outer side of the abutting movable member 20 and support member 21 and the inner side of the annular buckle 220. Then, the tip of the wedge-shaped member 221 can be inserted into the gap, and then the wedge-shaped member 221 can be pushed along the axial direction of the annular buckle 220 until the wedge-shaped member 221 is locked in the gap. After the wedge-shaped member 221 is locked in the gap, the squeezing force and friction force on the periphery of the wedge-shaped member 221 can be used to effectively restrict the movement of the movable member 20 relative to the support member 21, thereby effectively ensuring the overall structural stability of the movable component 2.

[0077] When it is necessary to disassemble the connecting structure 22, an external object can be used to push the wedge 221 in the opposite direction, causing it to exit the gap. After the wedge 221 exits the gap, the annular latch 220 is moved away from the moving part 20 or the support part 21 to prevent it from obstructing the relative movement between them. It should be noted that because the wedge 221 is triangular prism or triangular pyramid, pushing it in the opposite direction only requires it to move a short distance within the gap to exit, effectively improving its usability.

[0078] In order to prevent the ring buckle 220 from affecting the stability of the support member 21 on the ground, the axial direction of the ring buckle 220 needs to extend vertically. Correspondingly, the wedge-shaped member 221 enters and exits the gap inside the ring buckle 220 vertically.

[0079] Alternatively, as shown in Figure 5, the connecting structure 22 may also include a connecting bolt 222 and a connecting nut 223; both the moving part 20 and the supporting part 21 are provided with through holes adapted to the connecting bolt 222. After the connecting bolt 222 passes through the through holes on the moving part 20 and the supporting part 21, it is threadedly connected to the connecting nut 223. One of the bolt head of the connecting bolt 222 and the connecting nut 223 abuts against the outside of the side wall of the moving part 20, and the other abuts against the outside of the side wall of the supporting part 21.

[0080] By connecting and separating the threaded connection between the connecting bolt 222 and the connecting nut 223, the moving part 20 and the support part 21 can be fixed and unlocked, thereby realizing the overall structural stability of the moving component 2 and the movement process of the moving part 20 relative to the support part 21.

[0081] Optionally, as shown in Figure 5, the through hole on the movable member 20 can pass through the inclined surface of the movable member 20 in a horizontal direction. Correspondingly, the through hole on the support member 21 can pass through the inclined surface of the movable member 20 in a horizontal direction. In this case, the connecting bolt 222 inside the through hole extends in a horizontal direction. The connecting bolt 222 will not affect the stability of the support member 21 on the ground, and the connecting bolt 222 and the connecting nut 223 have a relatively open space around them, which effectively improves the performance of the connection structure 22.

[0082] As shown in Figures 2 and 3, the support assembly 1 includes multiple support groups, which are stacked and connected from bottom to top. As shown in Figures 3 and 6, each support group includes multiple support modules 10 that are distributed and connected in pairs along the horizontal direction. In the multiple support groups, each support module 10 in the bottom support group is equipped with a movable component 2 at its bottom.

[0083] At this time, the bracket assembly 1 is formed by splicing multiple bracket modules 10 in the horizontal and vertical directions. The two adjacent bracket groups can be connected to each other by plug-in or other connection methods, and the two adjacent bracket modules 10 can be connected to each other by the disc buckle 4 and plug rod shown in Figures 3 and 6.

[0084] Specifically, the disc buckle 4 has multiple insertion holes spaced apart along its circumference, and both ends of the insertion rod have insertion blocks adapted to the insertion holes. Each bracket module 10 has a disc buckle 4 at its corner. The insertion rod can be a horizontal insertion rod 5 extending in the horizontal direction, as shown in Figure 3. A horizontal insertion rod 5 as shown in Figure 9 is inserted between the top disc buckles 4 of two adjacent bracket modules 10, and a horizontal insertion rod 5 as shown in Figure 9 is inserted between the bottom disc buckles 4. Optionally, the bracket module 10 may also include a diagonal brace 6 as shown in Figures 3 and 10, which can be hinged between the top and bottom horizontal insertion rods 5 of the bracket module 10.

[0085] It should be noted that there is no limit to the number of movable components 2 installed at the bottom of each support module 10 in the bottom support group, and the number can be selected according to actual needs. For example, the bottom of the support module 10 includes four corners, and movable components 2 can be installed at each of the four corners of the bottom of the support module 10.

[0086] Alternatively, to improve the stability of the support assembly 1 while ensuring smooth movement, as shown in Figures 2 and 3, a movable component 2 can be installed at each of the two diagonally opposite corners of the bottom of the support module 10. The other two diagonally opposite corners can be fitted with adjustable bases 7, as shown in Figures 2, 3, and 12, which can extend or retract. The top of the adjustable base 7 connects to the corner of the support module 10, and it is configured to extend during construction until the bottom of the adjustable base 7 touches the ground. At this point, the adjustable base 7 effectively improves the overall stability of the support assembly 1. After construction is completed, the adjustable base 7 can be retracted to facilitate movement of the support assembly 1, thus lifting the bottom of the adjustable base 7 off the ground.

[0087] To improve the ease of transportation and storage of the support assembly 1, this embodiment preferably uses a folding structure for each support module 10. Specifically, as shown in Figures 6-8, the support module 10 includes a folding frame 100 and a limiting rod 101; as shown in Figures 7 and 8, the folding frame 100 includes multiple hinge rods, which are hinged to each other to enable the folding frame 100 to be folded and unfolded; as shown in Figure 6, the limiting rod 101 is configured to connect between the hinge rods of the folding frame 100 after the folding frame 100 is unfolded, so as to restrict the folding of the folding frame 100.

[0088] The multiple hinged rods in the folding frame 100 can be divided into uprights 1000 and rotating rods 1001. There are multiple uprights 1000, which are distributed at intervals along the circumference of the folding frame 100. Each upright 1000 has two rotating rods 1001 hinged to one side facing the central axis of the folding frame 100. The two rotating rods 1001 are respectively hinged to the top and bottom of the upright 1000. The ends of the rotating rods 1001 at the top of the multiple uprights 1000 that are away from the uprights 1000 are hinged to one point, and the ends of the rotating rods 1001 at the top of the multiple uprights 1000 that are away from the uprights 1000 are hinged to another point.

[0089] To improve the hinge stability between the ends of the multiple rotating rods 1001, as shown in Figures 7 and 11, the folding frame 100 may also include a hinge member 1002. The hinge member 1002 has multiple rotating grooves on its periphery, and the ends of the multiple rotating rods 1001 that are away from the upright 1000 are hinged to the multiple rotating grooves in a corresponding manner.

[0090] When the folding frame 100 is folded, as shown in Figure 8, each rotating rod 1001 is folded to one side of the upright 1000 and parallel to the upright 1000. When the folding frame 100 is unfolded, by pulling the multiple uprights 1000 away from each other, the multiple rotating rods 1001 can be rotated simultaneously, as shown in Figure 7. When the rotating rods 1001 rotate to a state perpendicular to the uprights 1000, the folding frame 100 can be unfolded.

[0091] When the folding frame 100 is unfolded, in order to ensure the unfolding stability of the folding frame 100, as shown in Figure 6, a limiting rod 101 can be connected between two adjacent uprights 1000 of the folding frame 100. The limiting rod 101 can play a supporting role and effectively prevent the folding frame 100 from folding automatically.

[0092] Optionally, as shown in Figures 6 and 7, a disc buckle 4 can be fixed to the top of the upright 1000; or, as shown in Figures 13, 14, 15, and 16, disc buckles 4 can be fixed to both the top and bottom of the upright 1000; or, as shown in Figures 17, 18, 19, and 20, a disc buckle 4 can be fixed to the bottom of the upright 1000. The disc buckle 4 is configured to connect the folding frame 100 to the limiting rod 101. Corresponding to the structure of the disc buckle 4, each end of the limiting rod 101 has a plug that matches the insertion hole on the disc buckle 4. When it is necessary to connect the limiting rod 101 to the upright 1000, the plug on the limiting rod 101 is inserted into the insertion hole on the disc buckle 4.

[0093] As shown in Figure 21, this embodiment also provides a method for installing and removing a support device, which, when using the aforementioned support device, includes:

[0094] Step S1: Move both the bracket assembly 1 with the movable part 20 installed at the bottom and the support part 21 to the area to be constructed, and place the movable part 20 against the top of the support part 21, so that the movable part 20 and the support part 21 are in a beveled fit.

[0095] Step S2: Connect the connecting structure 22 between the movable member 20 and the support member 21 to restrict the movement of the movable member 20 relative to the support member 21;

[0096] Step S3: Perform construction on the top of the support assembly 1 at the area to be constructed. After the construction is completed, disassemble the connecting structure 22.

[0097] Step S4: Move the movable member 20 along the inclined plane between it and the support member 21 to reduce the ground clearance of the top of the support assembly 1;

[0098] Step S5: Pull the moving component 2 horizontally to remove the support component 1 from below the construction site.

[0099] Steps S1-S2 are the installation process of the above-mentioned support device, and steps S3-S5 are the disassembly process of the above-mentioned support device. Since the support device installation and disassembly method provided in this embodiment uses the above-mentioned support device, the support device installation and disassembly method can also ensure the stability of the support assembly 1 through the connection structure 22. After the construction of the construction site is completed using the support assembly 1, the moving part 20 is used to move at the inclined surface between it and the support part 21 to reduce the height of the top of the support assembly 1 from the ground, so as to facilitate the removal of the entire support assembly 1 from below the construction site and avoid construction personnel throwing the poles from the air because the poles occupy the construction site.

[0100] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure. Industrial applicability

[0101] The support device provided in this disclosure can ensure the stability of the support assembly through the connection structure. After the construction of the construction site is completed using the support assembly, the height of the top of the support assembly off the ground can be reduced by moving the movable part at the inclined surface between it and the support member. This allows the support assembly to be separated from the construction site, making it easier to move the entire support assembly away from below the construction site and disassemble it elsewhere. This avoids construction workers throwing poles from high altitudes due to poles encroaching on the construction site, thereby effectively reducing construction risks.
