Description

Technical Field

[0001] This invention relates to the field of construction technology, and in particular to a removable prefabricated support frame for low-carbon prefabricated houses and its usage method. Background Technology

[0002] Prefabricated buildings are increasingly used in residential and public buildings due to their advantages of high efficiency, low material waste, and minimal on-site pollution. Prefabricated support frames, as a key auxiliary structure for on-site assembly of prefabricated houses, must ensure construction safety, achieve precise component positioning, and distribute loads. However, current industry demands for faster construction cycles, cost control, and material recycling are constantly increasing, making traditional prefabricated support frames insufficient.

[0003] Existing prefabricated housing support frames have several specific defects: support columns and connecting parts are mostly fixed by welding, which requires large welding equipment and professional technicians, takes a long time to assemble, requires destructive cutting during disassembly, and components cannot be reused after damage, which increases construction waste and violates the concept of low carbon; the combination frame uses ordinary steel, which is heavy and increases the load on the house foundation and is prone to rust. At the same time, it lacks a spacing adjustment structure, and custom components are required for house types with different wall distances, which is costly and has a long construction period. Summary of the Invention

[0004] To overcome the above shortcomings, this invention provides a removable prefabricated support frame for low-carbon prefabricated houses and a method for using it, aiming to improve the problem that some devices lack spacing adjustment structures and require customized components for house types with different wall distances.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a removable prefabricated support frame for low-carbon prefabricated housing, comprising support columns, connecting components for detachable connection of the support columns, reinforcing components for enhancing support stability, and load-bearing components for supporting the prefabricated structure of the house. The connecting components include a plug fixedly connected to the top of the support column and a cylindrical connector matching the plug. The bottom of the cylindrical connector has a groove adapted to the shape of the plug, and the plug and the cylindrical connector are detachably connected through the groove. The reinforcing components include an inclined support fixedly connected to the top of the cylindrical connector and a connecting rod connecting adjacent support columns. The support structure is a triangular stability structure. Each support column has an overlapping plate fixedly connected to its outer wall. The two ends of the connecting rod are detachably connected to the overlapping plates of the adjacent support columns, and the width of the connecting rod is the same as the inner width of the overlapping plate. The load-bearing component includes an assembly plate erected between adjacent support columns and a combination frame fixedly connected to the bottom surface of the assembly plate. The assembly plate is a composite plate, and the combination frame is made of aluminum alloy. A triangular frame is fixedly connected inside the combination frame. A cross member is fixedly connected to the top surface of the combination frame. The two ends of the cross member are detachably connected to the adjacent support columns, and the cross member fits tightly against the top surface of the assembly plate to adjust the distance between the assembly plate and the building wall.

[0006] Preferably, a pad is provided on the side of the assembly plate away from the house wall, and an adjusting column is fixedly connected to the center of the top surface of the pad. The pad is welded to the bottom of the adjusting column, and a preset plate is provided at the top of the adjusting column. The preset plate adopts a nested structure of inner rod and outer rod. When the inner rod is moved up, it is fixed with a bolt through the outer rod. When it is moved down, the inner rod is lowered and then fixed with a bolt through the outer rod.

[0007] Preferably, the sliding plate is disposed on the ground and is at the same horizontal line as the pad; a groove is provided directly above the sliding plate, and a diagonal rod is installed directly above the sliding plate. The end of the diagonal rod away from the sliding plate is hinged to the preset plate and can be locked. The end of the diagonal rod near the sliding plate can rotate in the groove. When the preset plate rises or falls, the diagonal rod will tilt accordingly, and the sliding plate will move horizontally accordingly.

[0008] Preferably, sleeves are fixedly connected to the left and right sides of the pad, the sleeves are hollow inside, and a telescopic rod is threaded to the top of the sleeve. The end of the telescopic rod away from the sleeve is connected to the assembly plate.

[0009] Preferably, a crossbeam is fixedly connected to the outer side wall of the composite frame along its length, and the two ends of the crossbeam are fixedly connected to the inner side wall of the adjacent support column, respectively.

[0010] Preferably, the bottom end of the sleeve is provided with a ball head, and the pad and the sleeve are connected through the ball head.

[0011] Preferably, a main arm is fixedly connected between adjacent cylindrical joints, the cylindrical joints are welded to the main arm, and the main arm is in contact with the assembly plate directly below it.

[0012] Preferably, the support column is welded to the plug, the support column is welded to the lap plate, the assembly plate is bolted to the combination frame, and the combination frame is welded to the tripod.

[0013] A method for using a removable prefabricated support frame for low-carbon prefabricated housing includes the following steps:

[0014] S1 On-site preparation: Place the pad in the center area of ​​the house to be assembled, adjust the height of the pre-set plate, move the inner rod of the pre-set plate up or down, and after the corresponding position is determined, use the bolts through the outer rod to fix the inner rod until the top of the diagonal support is sufficient to support the top of the house.

[0015] S2 core component connection: The plug at the top of the support column is connected to the cylindrical connector through a groove, thus completing the connection between the support column and the cylindrical connector;

[0016] S3 Support Structure Installation: Connect both ends of the connecting rod to the overlapping plates of the adjacent support columns to form an integrated support system from multiple support columns; simultaneously, place the sliding plate on the ground, ensuring it is level with the pad; place one end of the diagonal rod in the groove of the sliding plate, allowing it to rotate within the groove; the other end is hinged to the preset plate and can be locked; when the preset plate rises or falls, the diagonal rod tilts accordingly, and the sliding plate moves horizontally accordingly, finally locking the hinge;

[0017] S4 load-bearing component fixing: Weld the tripod to the combination frame, then fix the combination frame to the bottom of the assembly plate with bolts, set up the assembly plate between adjacent support columns, adjust the length of the cross members, fix the two ends of the cross members to the support columns, and ensure that the assembly plate fits against the side of the house;

[0018] S5 Overall Reinforcement: Rotate the ball head at the bottom of the sleeve to rotate the sleeve and adjust the extension length of the telescopic rod so that the telescopic rod firmly presses against the inner assembly plate. Then fix both ends of the boom to the cylindrical joint to complete the overall reinforcement of the frame.

[0019] S6 Frame Demolition: After the main structure of the house is assembled, the connecting structure between the main arm and the assembly plate, the telescopic rod, the cross rod, the connecting rod, the assembly plate, and the combination frame are removed in sequence. Finally, the diagonal support is pulled upward to separate the support column, thus separating the plug from the cylindrical joint and completing the demolition of the entire frame.

[0020] Preferably, in step S4, the fixed assembly plate needs to be fitted to the side of the house; in step S5, after adjusting the telescopic rod, it is necessary to ensure that the entire preset support frame reaches a stable state.

[0021] The present invention has the following beneficial effects:

[0022] 1. In this invention, the device significantly improves the practicality, stability, and adaptability of the prefabricated house support frame through modularly designed connecting components, reinforcing components, and load-bearing components. In the connecting components, a plug is fixed at the top of the support column, paired with a cylindrical connector with a matching groove at the bottom. The two are detachably connected via the groove, eliminating the complex welding process of traditional frames. Installation can be quickly completed without large professional tools, significantly reducing construction difficulty. Later, only the plug and cylindrical connector need to be separated to achieve non-destructive disassembly of the support column and connecting components. The components can be reused, reducing building material waste and aligning with the low-carbon concept.

[0023] The reinforcement components specifically address the problem of insufficient support in traditional frames. The inclined support at the top of the cylindrical joint has a triangular stable structure inside, which can effectively disperse the vertical pressure on the roof and prevent the frame from tilting or collapsing. The lap plate on the outside of the support column works with the connecting rod. The width of the connecting rod is the same as the inner width of the lap plate, which can integrate multiple support columns into a whole support system, evenly distribute the force, and improve the frame's resistance to lateral displacement.

[0024] The load-bearing components use composite panels that combine lightweight and high strength as assembly plates, which facilitates transportation and erection and reduces the labor intensity of construction workers. The combination frame is made of aluminum alloy, which is lightweight and corrosion-resistant. The internal triangular frame can strengthen the structural strength and ensure stable support for the pre-assembled house structure. The cross members on the top surface of the combination frame fit with the assembly plate and can be detached at both ends. The length can be adjusted to adapt to different room types with different wall distances, solving the problem of poor adaptability of traditional frames.

[0025] 2. In this invention, the mounting plate is located on the side of the building wall away from the pad. The top of the adjustable column, which is fixed at the center of the top surface, is equipped with a preset plate. The preset plate adopts an inner rod and outer rod nesting structure. When the inner rod moves up, it is fixed by the outer rod through bolt. When it moves down, the inner rod is lowered and then fixed by bolt. This can flexibly adapt to the roof of buildings of different heights, ensuring that the top of the inclined support accurately reaches the support position. The sliding plate is located on the ground and at the same height as the pad. The groove directly above it can position the inclined rod. One end of the inclined rod rotates with the groove, and the other end is locked and hinged to the preset plate. When the preset plate is raised or lowered, the inclined rod tilts and the sliding plate moves horizontally, which can eliminate the instability of the single rod support of the adjustable column and prevent the preset plate from shaking.

[0026] The sleeves on both sides of the pad are hollow, and the extension rods with threaded connections at the top can be adjusted by rotating the sleeves. Combined with the ball joints at the bottom of the sleeves, the support angle can be flexibly adjusted, ensuring the extension rods firmly support the assembly plate and distribute its weight from the side, preventing deformation. The ball joints also allow the sleeves to rotate with the tilt angle of the assembly plate, improving adaptability. The two ends of the crossbeams on the outer side of the composite frame are fixed to the inner sides of the adjacent support columns, tightly connecting the load-bearing components and the support system, enhancing the frame's torsional resistance and preventing displacement of the composite frame and support columns due to uneven weight distribution. The large arms between adjacent cylindrical joints fit snugly against the assembly plate, transferring the pressure of the diagonal supports to the assembly plate, achieving secondary stress distribution and preventing the diagonal supports from breaking under independent stress. The clearly defined welding and bolting connections ensure the connection strength of key components such as the support columns and plugs, lap plates, and the composite frame and tripods, preventing loosening of joints; while also preserving the detachability of components such as the assembly plate and composite frame for easy future recycling.

[0027] The usage method follows a clear and standardized process, from adjusting the preset plate height to connecting core components, installing support structures, fixing load-bearing components, and overall reinforcement. Each step is designed with safety and stability in mind. During dismantling, the operation follows the order of "secondary components first, then core components." First, dismantle auxiliary components such as the boom and telescopic rods, then dismantle the assembly plates and combination frames, and finally separate the support columns from the cylindrical joints. This prevents the frame from collapsing, and all detachable parts can be recyclable, reducing construction waste and further implementing the low-carbon concept. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1, refer to Figures 1-5 A low-carbon prefabricated house removable prefabricated support frame includes support columns 1, connecting components for detachable connection of the support columns 1, reinforcing components for enhancing support stability, and load-bearing components for supporting the prefabricated house structure. The connecting components include a plug 8 fixedly connected to the top of the support column 1, and a cylindrical connector 5 matching the plug 8. The bottom of the cylindrical connector 5 has a groove adapted to the shape of the plug 8, and the plug 8 and the cylindrical connector 5 are detachably connected through the groove. The reinforcing components include an inclined support 6 fixedly connected to the top of the cylindrical connector 5, and a connecting rod 7 connecting adjacent support columns 1. The inclined support 6 has a triangular stabilizing structure inside. Each support column... An overlapping plate 2 is fixedly connected to the outer wall. The two ends of the connecting rod 7 are detachably connected to the overlapping plate 2 of the adjacent support column 1, and the width of the connecting rod 7 is the same as the inner width of the overlapping plate 2. The load-bearing component includes an assembly plate 4 erected between the adjacent support columns 1, and a combination frame 14 fixedly connected to the bottom surface of the assembly plate 4. The assembly plate 4 is a composite plate, and the combination frame 14 is made of aluminum alloy. A triangular frame 15 is fixedly connected inside the combination frame 14. A cross member 16 is fixedly connected to the top surface of the combination frame 14. The two ends of the cross member 16 are detachably connected to the adjacent support column 1, and the cross member 16 is tightly fitted to the top surface of the assembly plate 4 to adjust the distance between the assembly plate 4 and the house wall.

[0037] By detachably connecting the plug 8 at the top of the support column 1 in the connecting component with the cylindrical connector 5 with the matching groove, the triangular stabilizing structure of the inclined support 6 at the top of the cylindrical connector 5 in the reinforcing component, the tight connection between the connecting rod 7 and the outer overlapping plate 2 of the support column 1, the synergistic effect of the composite plate assembly plate 4 in the load-bearing component, the aluminum alloy combination frame 14 and the cross rod 16 on the top surface of the combination frame 14, the frame installation efficiency, overall stability and room type adaptability can be improved and the waste of building materials can be reduced. This is because the detachable connection eliminates the complex welding process, the triangular structure has strong resistance to bending deformation, the composite plate and aluminum alloy are lightweight and high-strength, and the cross rod 16 can be adjusted in length to adapt to different wall spacings.

[0038] Example 2, refer to Figures 1-5 Based on Embodiment 1, a pad 12 is provided on the side of the assembly plate 4 away from the building wall. An adjusting column 13 is fixedly connected to the center of the top surface of the pad 12. The bottom of the pad 12 and the adjusting column 13 are welded together, and a pre-set plate 17 is provided at the top of the adjusting column 13. The pre-set plate 17 adopts a nested structure of inner and outer rods. When the inner rod is moved upward, it is fixed with a bolt through which the outer rod passes. When it is moved downward, the inner rod is lowered and then fixed with a bolt through which the outer rod passes. The adjusting column 13 on the top surface of the pad 12 on the side of the assembly plate 4 away from the wall works in conjunction with the pre-set plate 17. The inner and outer rod structure of the pre-set plate 17 can adapt to roofs of different heights and ensure a reliable and fixed height. This is because the inner and outer rods of the pre-set plate 17 can be flexibly adjusted in height, and the bolts can be locked in place to ensure stable position, without relying on the self-extension and contraction of the adjusting column 13. The sliding plate 11 is set on the ground and is on the same horizontal line as the pad 12. A groove is provided directly above the sliding plate 11, and a diagonal rod 10 is installed directly above the sliding plate 11. The end of the diagonal rod 10 away from the sliding plate 11 is hinged to the pre-set plate 17 and can be locked. One end of the 10 near the sliding plate 11 can rotate within the groove; when the preset plate 17 rises or falls, the inclined rod 10 will tilt accordingly, and the sliding plate 11 will move horizontally accordingly. Through the cooperation of the sliding plate 11 and the inclined rod 10, the instability of the single-rod support of the adjusting column 13 can be eliminated and the wobbling of the preset plate 17 can be prevented. This is because the inclined rod 10 can adapt to the tilt angle as the preset plate 17 rises and falls, and the sliding plate 11 moves horizontally synchronously to ensure the stability of the support point. The lockable hinge can be fixed after the angle is adapted to avoid loosening; the left and right sides of the pad 12 are divided into A sleeve 9 is fixedly connected. The sleeve 9 has a hollow internal structure. A telescopic rod 18 is threadedly connected to the top of the sleeve 9. The end of the telescopic rod 18 away from the sleeve 9 is connected to the assembly plate 4. The sleeves 9 on the left and right sides of the pad 12 cooperate with the telescopic rod 18 at the top. The extension length of the telescopic rod 18 can be adjusted so that its top end presses against the assembly plate 4. This can provide additional support to the assembly plate 4 from the side to prevent it from deforming under long-term stress. This is because the threaded connection between the sleeve 9 and the telescopic rod 18 can precisely adjust the extension length. After the telescopic rod 18 is tightened, it can effectively distribute the weight borne by the assembly plate 4.

[0039] Example 3, referring to Figures 1-5 Based on Embodiment 1 or Embodiment 2, a crossbeam 3 is fixedly connected to the outer side wall of the composite frame 14 along its length. Both ends of the crossbeam 3 are fixedly connected to the inner side walls of adjacent support columns 1. Connecting the two ends of the crossbeam 3 on the outer side wall of the composite frame 14 to the inner side walls of adjacent support columns 1 enhances the overall torsional resistance of the frame and prevents relative displacement between the composite frame 14 and support columns 1 due to uneven weight distribution in the pre-assembled structure. This is because the crossbeam 3 tightly connects the load-bearing components to the support system, allowing the force to be transmitted more evenly to the support columns 1. A ball head is provided at the bottom of the sleeve 9. The pad 12 and the sleeve 9 are connected through the ball head. The connection between the ball head at the bottom of the sleeve 9 and the pad 12 allows for flexible adjustment of the support angle of the sleeve 9 and the telescopic rod 18 to adapt to the possible tilting state of the assembly plate 4. This is because the ball head can rotate freely, allowing the sleeve 9 to move synchronously with the tilting angle of the assembly plate 4. The direction is adjusted; a large arm 19 is fixedly connected between adjacent cylindrical joints 5. The cylindrical joints 5 and the large arm 19 are welded together, and the bottom of the large arm 19 is in contact with the assembly plate 4. By the large arm 19 between adjacent cylindrical joints 5 and the assembly plate 4, the pressure borne by the diagonal support 6 can be transferred to the assembly plate 4 to achieve secondary force distribution and strengthen the connection between the cylindrical joints 5 and the assembly plate 4, so as to avoid the diagonal support 6 from breaking due to excessive stress alone; the support column 1 is welded to the plug 8, the support column 1 is welded to the overlapping plate 2, the assembly plate 4 is bolted to the combination frame 14, and the combination frame 14 is welded to the tripod 15. Through the welding of the support column 1 to the plug 8, the support column 1 to the overlapping plate 2, the combination frame 14 to the tripod 15, and the bolt connection of the assembly plate 4 to the combination frame 14, the connection strength of the key parts of the frame can be guaranteed to prevent the nodes from loosening, and at the same time, it is convenient to disassemble and recycle the parts later.

[0040] Example 4, refer to Figures 1-5 A method for using a removable prefabricated support frame for low-carbon prefabricated housing includes the following steps:

[0041] S1 On-site preparation: Place the pad 12 in the center area of ​​the house to be assembled, adjust the height of the preset plate 17, move the inner rod of the preset plate 17 up or down, and after the corresponding position is determined, use the bolts through the outer rod to fix the inner rod until the top of the inclined support 6 is sufficient to support the top of the house.

[0042] S2 core component connection: Connect the plug 8 at the top of the support column 1 to the cylindrical connector 5 through the groove to complete the connection between the support column 1 and the cylindrical connector 5;

[0043] S3 Support Structure Installation: Connect both ends of the connecting rod 7 to the overlapping plates 2 of the adjacent support columns 1 to form an overall support system from multiple support columns 1; at the same time, place the sliding plate 11 on the ground, ensuring that it is on the same horizontal line as the pad 12, place one end of the diagonal rod 10 in the groove of the sliding plate 11, allowing it to rotate within the groove, and connect the other end to the preset plate 17 via a hinge that can be locked; when the preset plate 17 rises or falls, the diagonal rod 10 tilts accordingly, and the sliding plate 11 moves horizontally accordingly, finally locking the hinge;

[0044] S4 Load-bearing component fixing: Weld the tripod 15 to the combination frame 14, and then fix the combination frame 14 to the bottom surface of the assembly plate 4 with bolts. Place the assembly plate 4 between adjacent support columns 1, adjust the length of the cross member 16 so that both ends of the cross member 16 are fixed to the support column 1, and ensure that the assembly plate 4 fits against the side of the house.

[0045] S5 Overall Reinforcement: Rotate the ball head at the bottom of the sleeve 9, operate the sleeve 9 to rotate, adjust the extension length of the telescopic rod 18, so that the telescopic rod 18 firmly presses against the inner assembly plate 4, and then fix the two ends of the upper arm 19 to the cylindrical joint 5 to complete the overall reinforcement of the frame.

[0046] S6 Frame Demolition: After the main structure of the house is assembled, the connecting structure between the main arm 19 and the assembly plate 4, the telescopic rod 18, the cross rod 16, the connecting rod 7, the assembly plate 4, and the combination frame 14 are removed in sequence. Finally, the diagonal support 6 is pulled upward to pull out the support column 1, so that the plug 8 is separated from the cylindrical connector 5, and the demolition of the entire frame is completed.

[0047] By placing the pad 12 in the central area step by step, adjusting the height of the inner and outer rods of the preset plate 17, connecting the plug 8 and the cylindrical connector 5, installing the connecting rod 7 and the matching diagonal rod 10 and sliding plate 11, fixing the assembly frame 14 and the assembly plate 4, adjusting the telescopic rod 18 and installing the boom 19, and finally dismantling the components in sequence, the construction process can be standardized to ensure the frame is stable and safe to dismantle, and the components can be recycled. This is because the orderly steps ensure the precise installation of each component, and the detachable structure and adaptive support design allow the components to be disassembled and reused without damage. In step S4, the fixed assembly plate 4 needs to be attached to the side of the house; in step S5, after adjusting the telescopic rod 18, it is necessary to ensure that the entire preset support frame reaches a stable state. By ensuring that the assembly plate 4 is attached to the side of the house in the load-bearing component fixing step, and ensuring the stability of the frame after adjusting the telescopic rod 18 in the overall reinforcement step, the load-bearing components can be accurately positioned and the overall construction safety of the frame can be ensured.

[0048] Working principle: First, on-site preparation is carried out. The pad 12 is placed in the center area of ​​the house to be assembled. By adjusting the positions of the inner and outer rods of the pre-set plate 17, the inner rod is fixed with bolts through the outer rod after the corresponding positions are determined. This ensures that the top of the subsequently installed diagonal support 6 can support the top of the house, laying the foundation for the frame construction. Next, the core component connection operation is carried out. The plug 8 at the top of the support column 1 and the cylindrical connector 5 are connected through the matching groove at the bottom of the cylindrical connector 5, completing the stable connection between the support column 1 and the cylindrical connector 5. This detachable connection method ensures the stability of the connection and provides convenience for subsequent disassembly. Subsequently, the support structure is installed. The two ends of the connecting rod 7 are connected to the overlapping plate 2, which is fixedly connected to the outer wall of the adjacent support column 1. Since the width of the connecting rod 7 is the same as the inner width of the overlapping plate 2, the connection can be ensured to be tight, allowing multiple support columns 1 to form an overall support system and improving the overall support capacity of the frame. At the same time, the sliding plate 11 is placed on the ground, ensuring that it is on the same horizontal line as the pad 12. One end of the diagonal rod 10 is placed in the groove of the sliding plate 11, and the other end is connected to the preset plate 17 through a lockable hinge. When the height of the preset plate 17 is appropriate, the diagonal rod 10 tilts accordingly, and the sliding plate 11 moves horizontally accordingly. Finally, the hinge is locked. The support of the diagonal rod 10 enhances the stability of the adjusting column 13 and the preset plate 17, preventing them from shaking.

[0049] After the support structure is erected, the load-bearing components are fixed. First, the tripod 15 is welded to the combined frame 14 to enhance the structural strength of the combined frame 14. Then, the combined frame 14 is fixed to the bottom of the assembly plate 4 with bolts. The assembly plate 4 is a composite plate, which is convenient for installation and transportation. The combined frame 14 is made of aluminum alloy, which combines lightweight and high strength. After that, the assembly plate 4 is placed between adjacent support columns 1. The length of the cross member 16 is adjusted so that its two ends are detachably connected to the support column 1 and fit against the top surface of the assembly plate 4. The cross member 16 ensures that the assembly plate 4 fits against the side of the house and adapts to the distance between the assembly plate 4 and the house wall. Next, overall reinforcement is carried out. Rotating the ball head at the bottom of the sleeve 9 causes the sleeve to rotate. The sleeve is hollow inside and its top is threadedly connected to the telescopic rod 18. Rotating the sleeve adjusts the extension length of the telescopic rod 18, allowing the telescopic rod 18 to firmly press against the inner mounting plate 4, further improving the stability of the mounting plate 4. Then, the two ends of the main arm 19 are welded to the adjacent cylindrical joints 5, so that the bottom of the main arm 19 fits against the mounting plate 4. The main arm 19 strengthens the connection between the cylindrical joints 5 and the mounting plate 4, ensuring that the diagonal support 6 is effectively fixed to the mounting plate 4, and finally, the preset support frame reaches a stable state. After the main structure of the house is assembled, the frame is dismantled in sequence: first, the connection structure between the main arm 19 and the mounting plate 4 is dismantled, then the telescopic rod 18, the cross member 16, and the connecting rod 7 are dismantled in sequence, then the mounting plate 4 and the combination frame 14 are removed, and finally the support column 1 is pulled upward to separate the plug 8 from the cylindrical joint 5, completing the dismantling of the entire frame. The whole process relies on the detachable design of each component, making the operation convenient and not affecting the main structure of the house.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
