Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a rapid-installation scaffold and its installation method. Background Technology

[0002] Construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of buildings, including foundation construction, main structure construction, roof construction, and decoration construction. Scaffolding refers to various supports erected on the construction site to facilitate workers' operations and solve vertical and horizontal transportation, thereby enabling workers to carry out construction work.

[0003] Most existing scaffolding is constructed using a combination of couplers and steel pipes, which requires the assembly and disassembly of a large number of bolts, making the construction process quite cumbersome.

[0004] Chinese patent CN117552607B discloses a quick-assembly scaffold for construction, including horizontal connecting steel pipes, vertical connecting steel pipes, and longitudinal connecting steel pipes. A quick-connect module is installed between the horizontal connecting steel pipes, vertical connecting steel pipes, and longitudinal connecting steel pipes. The quick-connect module includes a central connecting block. A locking rod is slidably inserted into one side surface of the central connecting block. Locking blocks are also inserted into the other five sides of the central connecting block. A docking end pipe located outside the central connecting block is fixed to the end of the locking block. The other end of the docking end pipe is connected to the horizontal connecting steel pipe, vertical connecting steel pipe, or longitudinal connecting steel pipe.

[0005] Regarding the aforementioned technologies, existing technologies utilize a triangular socket structure between the steel pipe and the fixing component to achieve quick connection of scaffolding. However, the socket structure between the steel pipe and the fixing component is difficult to withstand large radial shear forces. Furthermore, the existing quick connection methods for scaffolding require cumbersome steps, and the cost of processing the socket structure between the steel pipe and the fixing component is also high, making it difficult to achieve convenient assembly and disassembly of scaffolding.

[0006] Chinese patent CN104358407B discloses a scaffold that can be quickly installed, including uprights, horizontal bars and fixing plates. The fixing plates are cross-shaped and include four fixing ends around the perimeter and a fixing block in the middle. The uprights pass through the center of the fixing blocks. Each fixing end is equipped with a locking block, a return spring, a spring fixing plate and a roller.

[0007] Regarding the aforementioned technologies, existing technologies utilize a snap-fit ​​structure on a fixed plate that can extend and retract in opposite directions to snap the annular groove on the inner wall of the steel pipe, achieving rapid connection of the steel pipe. However, in actual operation, workers need to rotate the drive wheel, wait for the snap-fit ​​structure to retract, and then pull the steel pipe out axially to release the restriction on the steel pipe. Since the steel pipes of the scaffolding are quite long, workers cannot steadily pull out the steel pipe by holding the end of the pipe. Therefore, two people are often required to cooperate, with one person releasing the restriction and the other holding the middle of the steel pipe to pull it out. Furthermore, the existing snap-fit ​​structure can only limit the sliding of the steel pipe in the axial direction, and it is difficult to prevent the steel pipe from rotating on its own axis.

[0008] In summary, the scaffolding used in existing building construction is quite cumbersome to assemble and disassemble. Summary of the Invention

[0009] Based on this, the purpose of the present invention is to provide a quick-installation scaffold and its installation method to solve the technical problem of the cumbersome dismantling and assembly of scaffolds used in existing building construction.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a quick-installation scaffold, comprising a first steel pipe, a connecting column fixedly connected to the end of the first steel pipe, a first truncated cone fixedly connected to the end of the connecting column, a second truncated cone slidably connected to the connecting column on the same axis as the first truncated cone, and a shell structure, the shell structure having a central through-hole, and a fixing component installed at the through-hole, the end of the first steel pipe slidably connected to the shell structure perpendicular to the through-hole direction, and a limiting component for limiting the second truncated cone is also provided inside the shell structure. When the fixing component at the center of the shell structure is not installed, the first steel pipe can continue to move towards the center of the shell structure until the inclined surface of the second truncated cone contacts the limiting component, and when the first steel pipe leaves the shell structure, it will not be limited by the limiting component. The scaffold also includes a transverse connector for connecting two scaffolds in parallel vertical planes.

[0011] By adopting the above technical solution, the connection between the steel pipe and the shell can be quickly achieved through plug-in connection. When it is necessary to disassemble the steel pipe, it is only necessary to first remove the fixed structure in the center of the shell to provide space for the axial sliding of the steel pipe, and then push it in along the axis of the steel pipe and then pull it out immediately to complete the disassembly of the steel pipe. There is no need to disassemble or install a large number of bolts, which conveniently realizes the rapid assembly and disassembly of scaffolding.

[0012] The invention is further configured such that the shell structure is annular with a cylinder penetrating its center, including a first shell and a second shell connected in opposite directions. The first shell and the second shell are provided with sockets for inserting a first steel pipe at equal angular intervals in four directions in a vertical plane, and a groove is provided along the radial direction of the first steel pipe for each socket. A limiting block is slidably connected in the groove, and a spring is provided between the end of the limiting block and the inner wall of the groove. The side of the limiting block facing the first steel pipe is inclined. When the first shell and the second shell are equipped with a fixing component, the first cone is restricted from moving in the axial direction between the fixing component and the limiting block. A limiting structure for restricting the rotation of the first steel pipe is provided between the inner wall of the second shell and the outer wall of the first steel pipe.

[0013] Preferably, the first steel pipe can be easily inserted and removed between the first housing and the second housing.

[0014] The present invention is further configured such that a guide bar is fixedly connected to the inner wall of the second housing along the insertion and extraction direction of the first steel pipe, and the ends of the first steel pipe are provided with guide grooves that cooperate with the guide bar.

[0015] Preferably, the rotation of the first steel pipe along its own axis is restricted.

[0016] The invention is further configured such that a fixing plate is fixedly connected to the middle of the second housing, and a plug-in box is slidably connected to the middle of the first housing and the second housing. A second steel pipe passes through the two fixing plates of the second housing in a vertical plane that is parallel to each other. The second steel pipe passes through the plug-in box and is fixedly connected to the plug-in box. The two fixing plates of the second housing in a vertical plane that is parallel to each other are arranged opposite each other and will not interfere with the movement of the first cone.

[0017] Preferably, the fixing structure on the plug-in box allows for quick connection of the second steel pipe.

[0018] The invention is further configured such that a first housing is inserted into the center of the first housing, a second housing is inserted into the center of the second housing, a rotating shaft is rotatably connected through the center of the first housing, a limiting ear is fixedly connected to one end of the rotating shaft facing the second housing, an annular groove for accommodating the limiting ear is provided inside the second housing, a rotating block is fixedly connected to one end of the rotating shaft away from the second housing, the rotating block can be fixedly connected to a third steel pipe, a rotating block is rotatably connected to one end of the second housing away from the first housing, and the first steel pipes in mutually parallel vertical planes are interconnected.

[0019] Preferably, a cross-bracing structure is used to further enhance the strength of the scaffolding structure.

[0020] The invention is further configured such that the end of the third steel pipe is provided with a notch for fitting the rotating block, and the end of the third steel pipe is connected to the rotating block by bolts.

[0021] Preferably, the third steel pipe can be easily connected to the rotating block.

[0022] The invention is further configured such that a plug-in platform is fixedly connected to the second box body in the direction away from the first box body, and a second steel pipe can be inserted between the two oppositely arranged plug-in platforms, and the two ends of the second steel pipe are connected to the plug-in platform by bolts.

[0023] Preferably, the scaffolding is strengthened by using an inclined third steel pipe, which also allows the second steel pipe to be connected between the corresponding two second shells.

[0024] The present invention is further configured such that the limiting ear is semi-circular, and the rotating shaft can slide along the axial direction when the third steel pipe to which it is connected is vertically upward, and the limiting ear will be stuck into the annular groove when the shaft is vertically upward.

[0025] Preferably, when installing the third steel pipe, tilting the third steel pipe can achieve the limiting of the rotating shaft.

[0026] A method for quickly installing scaffolding, the process comprising the following steps:

[0027] Step 1: Connect the fixing structure to the center of the shell structure;

[0028] Step 2: Insert the first steel pipe into the shell structure;

[0029] Step 3: Connect two corresponding shell structures in two parallel vertical planes with the second steel pipe.

[0030] In summary, the present invention has the following main beneficial effects:

[0031] This invention utilizes a limiting block that can extend and retract in opposite directions within the shell structure. A frustum structure is fixedly connected to the end of the steel pipe via a connecting column. Simultaneously, another frustum facing the opposite direction is slidably connected to the connecting column along the axial direction. The connection between the steel pipe and the shell is quickly achieved through a plug-in method. When the steel pipe needs to be disassembled, it is only necessary to first remove the fixing structure at the center of the shell to provide space for the axial sliding of the steel pipe. Then, the steel pipe is pushed in along its axis and immediately pulled out to complete the disassembly. This eliminates the need to disassemble and install a large number of bolts, thus conveniently enabling the rapid assembly and disassembly of scaffolding.

[0032] The present invention arranges the second housings connected to the fixing plate facing each other, and slides the plug box into the first housing. The two coaxial plug boxes are fixedly connected to the second steel pipe by the plug pin, so that the crossbeam can be conveniently installed on the two sets of first housings and second housings. At the same time, the plug box restricts the extension of the first cone, thus maintaining the stable connection of the first steel pipe before the plug box is removed.

[0033] The present invention provides a support structure for connecting a third steel pipe by rotating the center of the first shell and the second shell. When the scaffold needs to be reinforced with cross diagonal braces, it can conveniently provide a fixed connection position for supporting the diagonal brace structure. It can also adapt to the angle of the connection position by adjusting the first steel pipe of different lengths, thereby making it more convenient to connect the steel pipes required for the scaffold.

[0034] This invention provides a scaffolding reinforcement structure by rotating the connection position of the diagonal bar at the center of the first shell, and setting a connection position for the insertion of the second steel pipe between the opposing second shells, while achieving convenient connection of the horizontal bars between the two second shells.

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0053] The embodiments of the present invention will now be described.

[0054] A type of quick-installation scaffolding, please refer to Figure 1-7 The first steel pipe 3 is included, and a connecting column 302 is fixedly connected to the end of the first steel pipe 3. Specifically, the two ends of the first steel pipe 3 are coaxially fixedly connected to the connecting column 302, and the end of the connecting column 302 is fixedly connected to the first truncated cone 303. The connecting column 302 is coaxially slidably connected to the second truncated cone 304, which faces the opposite direction to the first truncated cone 303. The diameter of the connecting column 302 is smaller than that of the first truncated cone 303 and the second truncated cone 304, and the diameter of the first truncated cone 303 is smaller than that of the second truncated cone 304.

[0055] It also includes a shell structure, which serves as a connector for the steel pipe. It does not require disassembly during use. The shell structure has a through-hole, and a fixing component is installed at the through-hole. The fixing component is used to limit the extension of the first cone 303. The end of the first steel pipe 3 is slidably connected to the shell structure perpendicular to the through-hole direction. The shell structure also has a limiting component for limiting the second cone 304. When the fixing component at the center of the shell structure is not installed, the first steel pipe 3 can continue to move towards the center of the shell structure until the inclined surface of the second cone 304 contacts the limiting component. When the first steel pipe 3 leaves the shell structure, it will not be limited by the limiting component. When disassembling the first steel pipe 3, it is only necessary to push the first steel pipe 3 along its own axis towards the center of the shell structure, and then the limiting component can be released and the first steel pipe 3 can be pulled out smoothly.

[0056] It also includes a transverse connector, which is used to connect two scaffolds in two parallel vertical planes. The transverse connector specifically includes a second steel pipe 4. In other embodiments, the transverse connector may also be a reinforced structure in which the first steel pipes 3 are connected by steel pipes in the prior art.

[0057] For details regarding the above embodiments, please refer to [link / reference]. Figure 1-7 The shell structure is annular with a cylinder running through its center. It includes a first shell 1 and a second shell 2 that are connected in opposite directions. The first shell 1 and the second shell 2 are provided with slots for inserting the first steel pipe 3 at equal angular intervals in four directions in a vertical plane. Corresponding to each slot, a groove 9 is provided along the radial direction of the first steel pipe 3. A limiting block 10 is slidably connected in the groove 9. A spring 11 is provided between the end of the limiting block 10 and the inner wall of the groove 9. Specifically, in this embodiment, there are two grooves 9 corresponding to the end of each first steel pipe 3. After the limiting blocks 10 in the two grooves 9 slide in opposite directions, they can limit the first cone 303.

[0058] Specifically, the side of the limiting block 10 facing the first steel pipe 3 is inclined. When the first housing 1 and the second housing 2 are equipped with a fixing component, the first cone 303 is restricted from moving in the axial direction between the fixing component and the limiting block 10. Specifically, after the first housing 1 and the second housing 2 are closed, a passage 12 is formed for each first cone 303 to pass through. The diameter of the passage 12 is larger than that of the first cone 303 and smaller than that of the second cone 304. When the second cone 304 contacts the housing at the passage 12, the limiting block 10 contacts the inclined surface of the second cone 304. A limiting structure for restricting the rotation of the first steel pipe 3 is provided between the inner wall of the second housing 2 and the outer wall of the first steel pipe 3, so as to facilitate the insertion and removal of the first steel pipe 3 between the first housing 1 and the second housing 2.

[0059] Furthermore, to prevent the first steel pipe 3 from rotating along its own axis, a guide bar 201 is fixedly connected to the inner wall of the second housing 2 along the insertion and extraction direction of the first steel pipe 3. Each end of the first steel pipe 3 is provided with a guide groove 301 that cooperates with the guide bar 201 to restrict the rotation of the first steel pipe 3 along its own axis. Specifically, the length of the guide groove 301 is greater than the length of the guide bar 201 to prevent the guide bar 201 from affecting the extension and retraction of the first steel pipe 3.

[0060] For details regarding the above embodiments, please refer to [link / reference]. Figure 1-4 A fixing plate 8 is fixedly connected to the middle of the second housing 2. A plug-in box 6 is slidably connected to the middle of the first housing 1 and the second housing 2. A second steel pipe 4 passes through the fixing plates 8 of the two second housing 2 in parallel vertical planes. The second steel pipe 4 passes through the plug-in box 6 and is fixedly connected to the plug-in box 6. Specifically, in this embodiment, the fixing component at the center of the housing structure is the plug-in box 6. The side wall of the plug-in box 6 has four planes, which correspond to the four planes of the inner walls of the first housing 1 and the second housing 2. When the plug-in box 6 is inserted into the housing structure, after the top surface of the first cone 303 contacts the plane of the side wall of the plug-in box 6, the plug-in box 6 has a limiting effect on the first cone 303, preventing the first cone 303 from passing through the through-hole 12. This, in conjunction with the limiting block 10, achieves the limiting of the first cone 303.

[0061] Specifically, the fixing plates 8 of the two second shells 2 in parallel vertical planes are arranged opposite each other and do not interfere with the movement of the first cone 303. The fixing structure on the plug-in box 6 allows the second steel pipe 4 to be quickly connected. The plug-in box 6 is fixedly connected with plug ears 601 in the direction away from the fixing plates 8 along the through direction of the shell structure. The plug ears 601 are provided with holes for matching the plug holes 401 on the second steel pipe 4. When the plug pin 7 is inserted into the hole on the plug ear 601 and the plug hole 401, the connection of the second steel pipe 4 can be completed. No bolts 17 are needed throughout the process, which further speeds up the assembly of the scaffolding and ensures the structural strength of the scaffolding.

[0062] A method for quickly installing scaffolding, the process comprising the following steps:

[0063] Step 1: Connect the fixing structure to the center of the shell structure. Specifically, in this embodiment, insert the plug box 6 from the center of the first shell 1 until it contacts the fixing plate 8.

[0064] Step 2: Insert the first steel pipe 3 into the shell structure. Specifically, during the insertion of the first steel pipe 3 into the shell structure, the inclined surface of the first cone 303 contacts the inclined surface of the limiting block 10, pushing the limiting block 10 towards the spring 11. The spring 11 is compressed until the inclined surface of the first cone 303 disengages from the limiting block 10. Under the elastic force of the spring 11, the limiting block 10 resets and contacts the connecting post 302. At this time, one end of the first cone 303 contacts the insertion box 6, while the other end contacts the plane of the limiting block 10. The limiting block 10 and the insertion box 6 together limit the first cone 303, quickly completing the insertion of the first steel pipe 3.

[0065] Step 3: Connect two corresponding shell structures in two parallel vertical planes using the second steel pipe 4. Specifically, use the second steel pipe 4 to pass through the center of the fixing plate 8 and the center of the plug box 6, aligning the through hole of the plug ear 601 on the plug box 6 with the plug hole 401 on the second steel pipe 4. Then, use a pin to pass through the hole on the plug ear 601 and the plug hole 401 to achieve a fixed connection for the second steel pipe 4. Connect the shell structures at both ends of the second steel pipe 4 for the first steel pipe 3 to plug into, and quickly complete the scaffolding erection.

[0066] In this embodiment, when it is necessary to dismantle the scaffold, first pull out the pins at both ends of the second steel pipe 4 and pull out the second steel pipe 4 inside the plug box 6, then take out the plug box 6 inside the two shell structures, and then the first steel pipe 3 plugged into the two shell structures can be dismantled.

[0067] Please refer to the attached instruction manual for details. Figure 5-6 During the process of pushing the first steel pipe 3 toward the center of the shell structure, the first cone 303 passes through the opening 12 between the first shell 1 and the second shell 2. When the second cone 304 is released to the inclined surface of the limiting block 10, the limiting block 10 will also slide in the slide groove 9 and compress the spring 11. Since the orientation of the second cone 304 is opposite to that of the first cone 303, after the limiting block 10 is compressed to the maximum stroke, it will correspond to the inclined surface of the second cone 304. At this time, the limiting block 10 releases the inclined surface of the second cone 304, and the second cone 304 is limited by the first shell 1 and the second shell 2 and cannot pass through the opening 12. The limiting block 10 has a clamping effect on the second cone 304.

[0068] Then, the first steel pipe 3 is pulled out, and the second cone 304 slides relative to the connecting column 302. The first cone 303 retracts and contacts the second cone 304. As the first steel pipe 3 continues to be pulled out, the inclined surface of the limiting block contacting the second cone 304 continues to be compressed. Since the planes of the first cone 303 and the second cone 304 are in close contact, and the diameter of the second cone 304 is larger than that of the first cone 303, the limiting block 10 can no longer limit the first cone 303 during the pulling out of the first steel pipe 3. In actual operation, it is only necessary to push the first steel pipe 3 inward and then pull it out, making the dismantling of the scaffolding very convenient.

[0069] A type of quick-installation scaffolding, please refer to Figure 1-11 Based on the first embodiment, the difference from the first embodiment is that a first box 13 is inserted into the center of the first housing 1, and a second box 14 is inserted into the center of the second housing 2, and there is no connecting fixing plate 8. Specifically, the thickness of the first box 13 is the same as that of the first housing 1, and the thickness of the second housing 2 is the same as that of the second box 14. Recessed step structures are provided on the surfaces of the first housing 1 and the second housing 2 that are far apart from each other. The protruding edges of the first box 13 and the second box 14 are used to cooperate with the step structures. After the first box 13 is inserted toward the center of the first housing 1, once the protruding edge of the first box 13 cooperates with the step structure, it can no longer move toward the second housing 2.

[0070] Furthermore, a pivot 15 is rotatably connected through the center of the first housing 13. A limiting ear 1501 is fixedly connected to one end of the pivot 15 facing the second housing 14. An annular groove 1402 for accommodating the limiting ear 1501 is provided inside the second housing 14. A rotating block 16 is fixedly connected to one end of the pivot 15 away from the second housing 14. The rotating block 16 can be fixedly connected to the third steel pipe 5. In this embodiment, in order to increase the structural strength of the scaffold, the third steel pipes 5 are cross-connected in the same layer of scaffold in the horizontal direction. The inclination directions of the two third steel pipes 5 corresponding to the first housing 1 and the second housing 2 are opposite. The rotating block 16 is rotatably connected to one end of the second housing 14 away from the first housing 13. The first steel pipes 3 in the parallel vertical planes are connected to each other. The cross diagonal brace structure further strengthens the structural strength of the scaffold.

[0071] For details regarding the above embodiments, please refer to [link / reference]. Figure 8-11 The end of the third steel pipe 5 is provided with a notch 501 for fitting the rotating block 16. The end of the third steel pipe 5 is connected to the rotating block 16 by bolts 17. Specifically, the cross-section of the rotating block 16 is a rectangle with one end curved. The curved end of the cross-section of the rotating block 16 faces the notch 501 of the third steel pipe 5. The notch 501 of the third steel pipe 5 engages with the rotating block 16.

[0072] Furthermore, in order to make the connection between the third steel pipe 5 and the rotating block 16 more stable, the rotating block 16 is provided with a second connecting hole 1601 in a direction orthogonal to the axis of the rotating shaft 15, while the third steel pipe 5 is provided with a first connecting hole 502 in a direction orthogonal to the notch 501. After the first connecting hole 502 and the second connecting hole 1601 pass through the bolt 17 and are tightened, the third steel pipe 5 can be stably fixed, so that the third steel pipe 5 can be easily connected to the rotating block 16. Specifically, after the bolt 17 connects the third steel pipe 5 and the rotating block 16, it can also strengthen the structural strength of the end of the third steel pipe 5, effectively preventing the end of the third steel pipe 5 from deforming.

[0073] For details regarding the above embodiments, please refer to [link / reference]. Figure 8-11 The limiting ear 1501 is semi-circular. Specifically, the first box 13 extends toward the second box 14 with a first positioning platform 1301 having a semi-circular cross-section. Similarly, the second box 14 extends toward the first box 13 with a second positioning platform 1401 having a semi-circular cross-section. The end face of the first positioning platform 1301 is flush with the end face of the annular groove 1402. During the rotation of the rotating shaft 15, the semi-circular limiting ear 1501 will rotate within the annular groove 1402. After rotation, the limiting ear 1501 will be unable to move axially because it enters the annular groove 1402 in the semi-circular space where the second positioning platform 1401 is located. Therefore, when the rotating shaft 15 is vertically upward, it can slide along the axial direction. Conversely, the limiting ear 1501 will be stuck in the annular groove 1402. When installing the third steel pipe 5, tilting the third steel pipe 5 can achieve the limiting of the rotating shaft 15.

[0074] A method for quickly installing scaffolding, the process comprising the following steps:

[0075] Step 1: Connect the fixing structure to the center of the shell structure. Specifically, in this embodiment, first insert the second box 14 into the second shell 2, and then make the side of the rotating block 16 corresponding to the rotating shaft 15 with the arc section facing upward, so that the limiting ear 1501 is offset from the part of the annular groove 1402 corresponding to the second positioning platform 1401. At this time, the first box 13 can be smoothly inserted into the shell structure. Then, rotating the rotating shaft 15 can complete the axial movement locking of the first box 13 and the second box 14.

[0076] Step 2: Similar to the first embodiment, insert the first steel pipe 3 into the shell structure. The difference from the first embodiment is that the angle of the rotating block 16 is rotated to adjust the angle of the rotating block 16. Rotate the diagonally opposite rotating blocks 16 at adjacent heights in the same vertical plane to the opposite state. Use the third steel pipe 5 to insert and connect the rotating blocks 16 and the bolts 17 respectively.

[0077] Step 3: Connect two corresponding shell structures in two parallel vertical planes with the second steel pipe 4. In this embodiment, since both ends of the shell structure are provided with inclined reinforcing structures, the second steel pipe 4 is connected to the first steel pipe 3 with fasteners in the prior art. The number of second steel pipes 4 is increased or decreased according to actual needs to achieve a stable connection of scaffolding in adjacent vertical planes.

[0078] In this embodiment, the scaffolding is dismantled differently from the first embodiment. First, the bolts 17 are removed and the third steel pipe 5 is removed. Then, the rotating shaft 15 is rotated to make the limiting ear 1501 offset from the second positioning platform 1401. Then, the first box 13 and the second box 14 are taken out along the through direction of the shell structure. Finally, the first steel pipe 3 is removed. In this embodiment, a small number of bolts 17 need to be removed during the dismantling and assembly of the scaffolding. Compared with the prior art, the dismantling and assembly speed is greatly improved, while the stability of the scaffolding structure is further improved. It is suitable for construction scenarios where the scaffolding needs to bear a large load.

[0079] A type of quick-installation scaffolding, please refer to Figure 1-12 Based on the second embodiment, the difference from the second embodiment is that the second box 14 is fixedly connected to the insertion platform 18 in the direction away from the first box 13. The second steel pipe 4 can be inserted between the two opposite insertion platforms 18. The insertion platform 18 can directly connect the second steel pipe 4 between the two shell structures, without the need to use the fasteners in the prior art to connect the second steel pipe 4 between the two first steel pipes 3.

[0080] This embodiment is suitable when the construction environment requires strengthening the scaffold structure but also needs to take into account the speed of scaffold assembly and disassembly. The two ends of the second steel pipe 4 are connected to the plug-in platform 18 by bolts 17. The inclined third steel pipe 5 is used to strengthen the scaffold and can also connect the second steel pipe 4 between the corresponding two second shells 2.

[0081] A method for quickly installing scaffolding, the process comprising the following steps:

[0082] Step 1: Similar to the second embodiment, first connect the fixing structure to the center of the shell structure;

[0083] Step 2: Insert the first steel pipe 3 into the shell structure. The difference from the second embodiment is that the third steel pipe 5 can only be connected between the rotating blocks 16 corresponding to the first shell 1.

[0084] Step 3: Connect two corresponding shell structures in two parallel vertical planes with the second steel pipe 4. Specifically, insert the two ends of the second steel pipe 4 into the corresponding insertion platform 18 of the two second shells 2, and then use bolts 17 to connect the insertion platform 18 and the second steel pipe 4.

[0085] In the actual installation of the scaffolding in this invention: before erecting the scaffolding, a suitable shell structure is selected according to the engineering design indicators, and the first steel pipe 3 is connected to the shell structure by plugging in. Then, the second steel pipe 4 or the third steel pipe 5 is installed according to the type of shell structure.

[0086] When dismantling the scaffolding, first dismantle the third steel pipe 5, then remove the fixing components at the center of the shell structure, and at the same time remove the second steel pipe 4. Finally, remove the first steel pipe 3 by pushing and then pulling.
