Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a quick-installation scaffold and an installation method thereof. Background Art

[0002] Construction refers to the production activities during the implementation stage of engineering construction, which is the construction process of various buildings, including foundation construction, main structure construction, roof construction, decoration construction, etc. Scaffolding refers to various supports set up at the construction site for workers to operate and solve vertical and horizontal transportation, which is convenient for workers to carry out construction work.

[0003] Most of the scaffolds in the prior art are constructed by combining fasteners and steel pipes. During the construction and dismantling process, a large number of bolts need to be disassembled and installed, and the construction process is relatively cumbersome.

[0004] A Chinese patent with relevant announcement number CN117552607B discloses a quick-install scaffold for construction, including transverse connecting steel pipes, vertical connecting steel pipes and longitudinal connecting steel pipes, and quick docking modules are installed between the transverse connecting steel pipes, the vertical connecting steel pipes and the longitudinal connecting steel pipes. The quick docking module includes a central connecting block, a locking pull rod is slidably inserted on the surface of one side of the central connecting block, and the other five side surfaces of the central connecting block are all driven and inserted with locking blocks, and the end of the locking block is fixed with a docking end pipe located outside the central connecting block, and the other end of the docking end pipe is connected to the transverse connecting steel pipe, the vertical connecting steel pipe or the longitudinal connecting steel pipe.

[0005] With regard to the above-mentioned related technologies, the prior art utilizes a triangular socket structure between a steel pipe and a fixed component to achieve quick connection of the scaffolding. The socket structure between the steel pipe and the fixed component is difficult to bear a large radial shear force, and the steps required for the existing scaffolding quick connection method are cumbersome, and the cost of processing the socket structure between the steel pipe and the fixed component is also high, making it difficult to achieve convenient disassembly and assembly of the scaffolding.

[0006] A Chinese patent with related announcement number CN104358407B discloses a quickly installed scaffolding, including vertical poles, horizontal poles and a fixed plate. The fixed plate is cross-shaped, including four fixed ends around and a central fixed block. The vertical pole passes through the center of the fixed block, and a card block, a return spring, a spring fixing plate and a reel are installed in each fixed end.

[0007] With regard to the above-mentioned related technologies, the prior art utilizes a clamping structure on a fixed plate that can telescope toward each other to clamp the annular groove on the inner wall of the steel pipe to achieve quick connection of the steel pipe. However, in actual operation, workers need to rotate the driving wheel, and after the telescopic clamping structure retracts, they can pull out the steel pipe axially to release the limit on the steel pipe. Since the steel pipe of the scaffolding itself is relatively long, workers cannot stably pull out the steel pipe by holding the end of the steel pipe. Therefore, two people are often required to cooperate, one of whom releases the limit, while the other holds the middle of the steel pipe to pull out the steel pipe. In addition, the existing clamping 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 about its own axis.

[0008] In summary, the disassembly and assembly of the scaffolding used in the existing building construction is relatively complicated. Summary of the invention

[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] The following describes an embodiment of the present invention based on its overall structure.

[0033] A quick-install scaffolding, see Figure 1-7 , comprising a first steel tube 3, the ends of the first steel tube 3 are fixedly connected with a connecting column 302, specifically, both ends of the first steel tube 3 are coaxially fixedly connected with the connecting column 302, the ends of the connecting column 302 are fixedly connected with a first frustum 303, the connecting column 302 is coaxially slidably connected with a second frustum 304 facing opposite to the first frustum 303, the diameter of the connecting column 302 is smaller than the first frustum 303 and the second frustum 304, and the diameter of the first frustum 303 is smaller than the second frustum 304; It also includes a shell structure, which serves as a connector of the steel pipe and does not need to be disassembled when in use. The center of the shell structure is through-connected, and a fixing component is installed at the through-connection. 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-connection direction of the shell structure. A limiting component for limiting the second cone 304 is also provided in the shell structure. When the fixing component at the center of the shell structure is not installed, the first steel pipe 3 can continue to move toward 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 again, 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 toward the center of the shell structure along its own axis, and then the limit can be released and the first steel pipe 3 can be smoothly pulled out; It also includes a transverse connector, which is used to connect scaffolds in two parallel vertical planes. The transverse connector specifically includes a second steel pipe 4. In other embodiments, the transverse connector can also be a reinforcement structure between the first steel pipes 3 using steel pipes connected in the prior art.

[0034] In the above embodiments, please refer to Figure 1-7 The shell structure is annular and the center is penetrated by a cylinder, including a first shell 1 and a second shell 2 which are closed and connected oppositely. The first shell 1 and the second shell 2 are provided with sockets for inserting the first steel pipe 3 at equal angles in four directions in a vertical plane, and each socket is provided with a slide groove 9 along the radial direction of the first steel pipe 3. A limiting block 10 is slidably connected in the slide groove 9, and a spring 11 is provided between the end of the limiting block 10 and the inner wall of the slide groove 9. Specifically, in the present embodiment, two slide grooves 9 are provided corresponding to the end of each first steel pipe 3, and the limiting blocks 10 in the two slide grooves 9 can play a limiting role on the first cone 303 after sliding towards each other.

[0035] Specifically, one side of the limit block 10 facing the first steel tube 3 is an inclined surface. When the first shell 1 and the second shell 2 are installed with a fixing assembly, the first cone 303 is restricted from moving in the axial direction between the fixing assembly and the limit block 10. Specifically, after the first shell 1 and the second shell 2 are closed, a through opening 12 for the first cone 303 to pass through will be formed corresponding to each first cone 303. The diameter of the through opening 12 is larger than the first cone 303 and smaller than the second cone 304. When the second cone 304 contacts the shell at the through opening 12, the limit block 10 contacts the inclined surface of the second cone 304. A limiting structure for limiting the rotation of the first steel tube 3 is provided between the inner wall of the second shell 2 and the outer wall of the first steel tube 3, so as to conveniently realize the insertion and removal of the first steel tube 3 between the first shell 1 and the second shell 2.

[0036] Furthermore, in order to prevent the first steel tube 3 from rotating along its own axis, a guide bar 201 is fixedly connected to the inner wall of the second shell 2 along the plugging and unplugging direction of the first steel tube 3, and the ends of the first steel tube 3 are provided with guide grooves 301 that cooperate with the guide bar 201 to limit the rotation of the first steel tube 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 telescopic sliding of the first steel tube 3.

[0037] In the above embodiments, please refer to Figure 1-4A fixing plate 8 is fixedly connected to the middle of the second shell 2, and a plug-in box 6 is slidably connected to the middle of the first shell 1 and the second shell 2. A second steel pipe 4 passes through the fixing plates 8 of the two second shells 2 in parallel vertical planes. The second steel pipe 4 also passes through the plug-in box 6 and is fixedly connected to the plug-in box 6. Specifically, in this embodiment, the fixed component at the center of the shell structure is specifically 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 shell 1 and the second shell 2. When the plug-in box 6 is inserted into the shell 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, so that the first cone 303 cannot pass through the through opening 12, and then cooperates with the limit block 10 to achieve the limiting of the first cone 303.

[0038] Specifically, the fixing plates 8 of the two second shells 2 in parallel vertical planes are arranged opposite to each other and will not interfere with the movement of the first cone 303. The second steel pipe 4 can be quickly connected by utilizing the fixing structure on the plug-in box 6. A plug-in ear 601 is fixedly connected to the plug-in box 6 in a direction away from the fixing plate 8 along the through direction of the shell structure. The plug-in ear 601 is provided with a hole for matching the plug hole 401 on the second steel pipe 4. When the hole on the plug-in ear 601 and the plug hole 401 are inserted with the pin 7, the connection of the second steel pipe 4 can be completed. There is no need to use the bolts 17 throughout the process, which further speeds up the assembly speed of the scaffolding and ensures the structural strength of the scaffolding.

[0039] A method for quickly installing a scaffold, the process comprising the following steps: Step 1: Connect the fixing structure to the center of the housing structure. Specifically, in this embodiment, insert the plug-in box 6 from the center of the first housing 1 until it contacts the fixing plate 8; Step 2: insert the first steel tube 3 into the shell structure. Specifically, during the process of inserting the first steel tube 3 into the shell structure, the inclined surface of the first cone 303 contacts the inclined surface of the limit block 10, and the limit block 10 is pushed toward the direction of the spring 11. The spring 11 is compressed until the inclined surface of the first cone 303 is out of contact with the limit block 10. The limit block 10 is reset and contacts the connecting column 302 under the elastic force of the spring 11. At this time, one end of the first cone 303 contacts the plug-in box 6, and the other end contacts the plane of the limit block 10. The limit block 10 and the plug-in box 6 jointly limit the first cone 303, and the plug-in of the first steel tube 3 is quickly completed. Step three: Use the second steel pipe 4 to connect two corresponding shell structures in two parallel vertical planes. Specifically, use the second steel pipe 4 to pass through the center of the fixing plate 8 and the center of the plug-in box 6, align the through hole of the plug-in ear 601 on the plug-in box 6 with the plug-in hole 401 on the second steel pipe 4, and then use the pin to pass through the hole on the plug-in ear 601 and the plug-in hole 401 to achieve a fixed connection for the second steel pipe 4, and connect the shell structure for the first steel pipe 3 to be plugged in at both ends of the second steel pipe 4 to quickly complete the construction of the scaffolding.

[0040] In this embodiment, when the scaffolding needs to be disassembled, first pull out the pins at both ends of the second steel pipe 4 and pull out the second steel pipe 4 in the plug-in box 6, then take out the plug-in box 6 in the two shell structures, and then the first steel pipe 3 plugged in the two shell structures can be disassembled.

[0041] Please refer to the instruction manual for details. Figure 5-6 In the process of pushing the first steel tube 3 toward the center of the shell structure, the first cone 303 passes through the through 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 limit block 10, the limit block 10 will also slide in the slide groove 9 and compress the spring 11. Since the direction of the second cone 304 is opposite to that of the first cone 303, the limit block 10 will correspond to the inclined surface of the second cone 304 after being compressed to the maximum stroke. At this time, the limit 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 through opening 12. The limit block 10 has a clamping effect on the second cone 304. Then the first steel tube 3 is pulled out, the second cone 304 slides relative to the connecting column 302, the first cone 303 is retracted and contacts the second cone 304, and during the process of continuing to pull out the first steel tube 3, the inclined surface of the limit block contacting the second cone 304 continues to be compressed. Since the planes of the first cone 303 and the second cone 304 fit each other, and the diameter of the second cone 304 is larger than the first cone 303, during the process of pulling out the first steel tube 3, the limit block 10 can no longer limit the first cone 303. In actual operation, it is only necessary to push the first steel tube 3 inward and then pull out the first steel tube 3, which makes the dismantling of the scaffolding also very convenient.

[0042] A quick-install scaffolding, see Figure 1-11, based on the first embodiment, the difference from the first embodiment is that a first box body 13 is inserted in the center of the first shell 1, a second box body 14 is inserted in the center of the second shell 2, and there is no connecting fixing plate 8. Specifically, the thickness of the first box body 13 is the same as that of the first shell 1, and the thickness of the second shell 2 is the same as that of the second box body 14. A recessed step structure is provided on the surfaces of the first shell 1 and the second shell 2 that are away from each other, and the edges of the first box body 13 and the second box body 14 protrude to cooperate with the step structure. After the first box body 13 is inserted toward the center of the first shell 1, it can no longer move toward the second shell 2 after the protrusion of the edge of the first box body 13 cooperates with the step structure.

[0043] Furthermore, a rotating shaft 15 is rotatably connected through the center of the first box body 13, and the rotating shaft 15 is fixedly connected to a limiting ear 1501 at one end facing the second box body 14. A ring groove 1402 for accommodating the limiting ear 1501 is opened in the second box body 14, and a rotating block 16 is fixedly connected to the end of the rotating shaft 15 away from the second box body 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 scaffolding, the third steel pipe 5 is cross-connected in the same layer of scaffolding in the horizontal direction, and the inclination directions of the two third steel pipes 5 corresponding to the first shell 1 and the second shell 2 are opposite, and the end of the second box body 14 away from the first box body 13 is rotatably connected to the rotating block 16, and the first steel pipes 3 in parallel vertical planes are connected to each other, and the cross diagonal rod structure is used to further strengthen the structural strength of the scaffolding.

[0044] In the above embodiments, please refer to Figure 8-11 A notch 501 for fitting the rotating block 16 is provided at the end of the third steel tube 5, and the end of the third steel tube 5 is connected to the rotating block 16 by a bolt 17. Specifically, the cross-section of the rotating block 16 is a rectangle with one end being an arc, and the end of the rotating block 16 with the arc cross-section faces the notch 501 of the third steel tube 5, and the notch 501 of the third steel tube 5 is snap-fitted with the rotating block 16.

[0045] Furthermore, in order to make the third steel tube 5 and the rotating block 16 more stably connected, the rotating block 16 is provided with a second connecting hole 1601 in a direction perpendicular to the axis of the rotating shaft 15, and the third steel tube 5 is provided with a first connecting hole 502 in a direction perpendicular to the recess 501. After the first connecting hole 502 and the second connecting hole 1601 are simultaneously passed through the bolt 17 and tightened, the third steel tube 5 can be stably fixed, so that the third steel tube 5 can be conveniently connected to the rotating block 16. Specifically, after the bolt 17 connects the third steel tube 5 and the rotating block 16, it can also play a role in strengthening the structural strength of the end portion of the third steel tube 5, thereby effectively avoiding end deformation of the third steel tube 5.

[0046] In the above embodiments, please refer to Figure 8-11 The limiting ear 1501 is semi-circular. Specifically, the first box body 13 extends a first positioning platform 1301 with a semi-circular cross-section toward the second box body 14. Similarly, the second box body 14 extends a second positioning platform 1401 with a semi-circular cross-section toward the first box body 13. The end face of the first positioning platform 1301 is flush with the end face of the annular groove 1402. The semi-circular limiting ear 1501 will rotate in the annular groove 1402 during the rotation of the rotating shaft 15. The rotating limiting ear 1501 will enter the annular groove 1402 in the semi-circular space where the second positioning platform 1401 is located and cannot move axially. Therefore, the rotating shaft 15 can slide along the axial direction when the third steel pipe 5 connected to it is vertically upward, otherwise the limiting ear 1501 will be stuck in the annular groove 1402. When the third steel pipe 5 is installed, the third steel pipe 5 can be tilted to achieve the limitation of the rotating shaft 15.

[0047] A method for quickly installing a scaffold, the process comprising the following steps: Step 1: Connect the fixed structure to the center of the shell structure. Specifically, in this embodiment, first insert the second box body 14 into the second shell body 2, and then vertically point the arc-shaped side of the rotating block 16 corresponding to the rotating shaft 15 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 body 13 can be smoothly inserted into the shell structure, and then the rotating shaft 15 can be rotated to complete the axial movement locking of the first box body 13 and the second box body 14; Step 2: As in the first embodiment, the first steel pipe 3 is inserted into the housing structure. The difference from the first embodiment is that the angle of the rotating block 16 is adjusted by rotating, and the rotating blocks 16 arranged diagonally at adjacent heights in the same vertical plane are rotated to a relative state, and the third steel pipe 5 is used to respectively insert and match the rotating blocks 16 and connect the bolts 17; Step three: Use the second steel pipe 4 to connect the two corresponding shell structures in two parallel vertical planes. In this embodiment, since inclined reinforcement structures are provided at both ends of the shell structure, the second steel pipe 4 is connected between the first steel pipes 3 using 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 the scaffolding in adjacent vertical planes.

[0048] When the scaffolding in this embodiment is dismantled, it is different from the first embodiment in that the bolts 17 are first removed and the third steel pipe 5 is removed, and then the rotating shaft 15 is rotated to make the limit ear 1501 offset from the second positioning platform 1401, and then the first box body 13 and the second box body 14 are taken out respectively along the through direction of the shell structure, and finally the first steel pipe 3 is removed. In the process of disassembling and assembling the scaffolding, this embodiment needs to disassemble and assemble a small number of bolts 17, which greatly improves the disassembly and assembly speed compared with the prior art, and further improves the stability of the scaffolding structure, which is suitable for construction scenarios where the scaffolding needs to bear a large load.

[0049] A quick-install scaffolding, see Figure 1-12 On the basis of the second embodiment, the difference from the second embodiment is that the second box body 14 is fixedly connected with a docking station 18 in the direction away from the first box body 13, and the second steel pipe 4 can be inserted between the two oppositely arranged docking stations 18. The arrangement of the docking stations 18 can directly connect the second steel pipe 4 between the two shell structures, and there is no need to use fasteners in the prior art to connect the second steel pipe 4 between the two first steel pipes 3.

[0050] This embodiment is suitable for use when the construction environment requires strengthening the structural strength of the scaffolding, but also requires taking into account the speed of disassembly and assembly of the scaffolding. The two ends of the second steel pipe 4 are connected to the docking station 18 by bolts 17, and the inclined third steel pipe 5 is used to strengthen the strength of the scaffolding. At the same time, the second steel pipe 4 can also be connected between the corresponding two second shells 2.

[0051] A method for quickly installing a scaffold, the process comprising the following steps: Step 1: Same as the second embodiment, first connect the fixing structure to the center of the shell structure; Step 2: Insert the first steel tube 3 into the shell structure. The difference from the second embodiment is that only the rotating blocks 16 corresponding to the first shell 1 can be connected to the third steel tube 5. Step three: Use the second steel pipe 4 to connect two corresponding shell structures in two parallel vertical planes. Specifically, insert the two ends of the second steel pipe 4 into the corresponding plug-in platforms 18 of the two second shells 2, and then use bolts 17 to connect the plug-in platforms 18 and the second steel pipe 4.

[0052] The scaffolding of the present invention is actually installed as follows: before building the scaffolding, a suitable shell structure is selected according to the engineering design index, the first steel pipe 3 is connected to the shell structure by plugging, and then the second steel pipe 4 or the third steel pipe 5 is installed according to the type of the shell structure; When disassembling the scaffold, first disassemble the third steel pipe 5, then remove the fixing assembly at the center of the shell structure, and simultaneously disassemble the second steel pipe 4, and finally disassemble the first steel pipe 3 by first pushing and then pulling.
