Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, and in particular to a scaffolding system for prefabricated buildings. Background Technology

[0002] Prefabricated scaffolding is a construction tool consisting of standard parts, fasteners, and other accessories. It can be used to build a safe and reliable working platform outside or inside a building, providing support and protection for workers.

[0003] The technical solution disclosed in Chinese Patent No. CN216893376U uses a movable lever to move the connecting plate. The movement of the connecting plate causes the airbag and spring to generate elasticity, which in turn engages the locking block on the pedal with the slot of the limiting post. The elasticity of the airbag and spring causes the locking rod to engage with the locking hole for fixation. In this way, the four limiting posts are fixed to the four corners of the pedal to complete the assembly. When disassembling, the lever is moved to separate the locking rod from the locking hole, which avoids the need for multiple people to work on the assembly or disassembly of the scaffolding at the same time, thus saving a lot of energy and improving the convenience of using the scaffolding.

[0004] However, the device still has shortcomings: the prefabricated scaffolding has a large number of loose parts, which makes it very troublesome to assemble in practice, and the stability of the scaffolding is not easy to adjust when it is erected on uneven ground. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing a scaffolding method for prefabricated buildings.

[0012] Preferably, the support frame includes two support plates and a connecting plate. The two support plates are parallel to each other, and the connecting plate is located between the two support plates and connected to both support plates. Two cylindrical tubes are symmetrically arranged on the support plates. Each plug is inserted into the corresponding cylindrical tube and slidably connected to it. A second locking member is provided on the cylindrical tube. The second locking member includes a second knob and a second screw. The second screw is inserted into the cylindrical tube from the side and is screwed to it. The second screw is inserted into the annular groove, and the second knob is connected to the outer end of the second screw.

[0013] Preferably, the telescopic connector includes a guide sleeve and a slide rod. The guide sleeve is connected to the support plate and has a through hole communicating with its interior. The slide rod is located inside the guide sleeve and is slidably connected to its inner wall. The slide rod has an ear plate, and the end of the ear plate away from the slide rod extends outward along the through hole.

[0014] Preferably, the drive assembly includes a lead screw, a connecting rod, a worm gear, and a worm; a groove is provided on the upper part of the support plate, the lead screw is located in the groove and rotatably connected to its inner wall, a slider is provided in the groove and slidably connected to its inner wall, the lead screw passes through the slider and is helically connected to it; both ends of the connecting rod are rotatably connected to the corresponding side lugs and the slider, respectively; the worm gear is coaxially connected to the lead screw, the worm is rotatably connected to the support plate and meshes with the worm gear, and one end of the worm extending out of the support plate is connected to a crank.

[0016] Preferably, the two ends of the movable plate are connected to a second hook and a third hook, respectively, and the second hook is connected to the support rod where the fixing ring is located.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects:

[0018] By rotating a fixed ring on the support rod and connecting one end of the pedal to the fixed ring, each support component carries a set of pedal structures. This facilitates reducing the steps of transporting and splicing separate materials when assembling the scaffold layer by layer. Each pedal is rotatably connected to a set of movable plates, which, when unfolded, effectively increase the area for stepping during operation. Furthermore, this invention incorporates several independently adjustable telescopic components and casters, making it easy to level the support frame on uneven surfaces. This ensures the scaffold is placed stably on the support frame, improving its stability. Additionally, the drive component uses a worm gear and worm shaft combination structure, effectively preventing the support frame from tilting due to screw rotation. Attached Figure Description

[0024] Example 1

[0025] like Figures 1-4As shown, this utility model proposes a prefabricated building scaffolding, including a support assembly, a support frame 12, and a drive assembly 18. The support assembly includes two support columns 1, with a support rod 2 connecting them. A fixing ring 6, coaxially rotating with the support rod 2, is fitted around the outside of the rod. One end of a footboard 7 is connected to the fixing ring 6, and the end of the footboard 7 away from the fixing ring 6 is connected to a first hook 8. A plug 101 is provided at the bottom of the support column 1, and a socket 102 is provided at the top of the support column 1. The diameter of the socket 102 is the same as the outer diameter of the plug 101. Several reinforcing rods 3 are connected between adjacent support columns 1, and a ladder 4 is provided on the support column 1. The support frame 12 includes two support plates 121 and a connecting plate 122. The two support plates 121 are parallel to each other. The connecting plate 122 is located between the two support plates 121 and is connected to both support plates 121. Two columns 13 are symmetrically arranged on the support plates 121. The four plugs 101 of the two sets of support components are inserted into the corresponding columns 13 and slidably connected to them. Four sets of telescopic connectors are provided at the bottom of the support frame 12. The telescopic connectors include guide sleeves 15 and slide rods 16. The guide sleeves 15 are connected to the support plates 121 and have through holes 151 communicating with their interior. The slide rods 16 are located inside the guide sleeves 15 and slidably connected to their inner walls. The slide rods 16 have ear plates 161. The end of the ear plate 161 away from the slide rods 16 extends outward along the through holes 151. A set of casters 17 are connected to the bottom of the slide rods 16, and the casters are equipped with self-locking components. Several sets of drive components 18 with self-locking structures are connected to the support frame 12. Each drive component 18 includes a lead screw 181, a connecting rod 183, a worm gear 184, and a worm 185. A groove is provided on the upper part of the support plate 121. The lead screw 181 is located in the groove and is rotatably connected to its inner wall. A slider 182 is provided in the groove and is slidably connected to its inner wall. The lead screw 181 passes through the slider 182 and is helically connected to it. The two ends of the connecting rod 183 are rotatably connected to the ear plate 161 on the corresponding side and the slider 182, respectively. The worm gear 184 is coaxially connected to the lead screw 181. The worm 185 is rotatably connected to the support plate 121 and meshes with the worm gear 184. One end of the worm 185 extending out of the support plate 121 is connected to a crank 186.

[0026] In this embodiment, during actual operation, the support frame 12 is fixed to the ground. When the ground is uneven, the crank 186 on the corresponding side is driven. The crank 186 drives the worm gear 185 to rotate, which in turn drives the worm wheel 184 and the lead screw 181 to rotate. The slider 182 slides under the drive of the lead screw 181, which in turn drives the connecting rod 183 to move, thereby adjusting the height of the universal wheel 17 on that side, making it easier to adjust the support frame 12 to a horizontal state. Then, the two sets of support components are connected to the column cylinder 13 on the support frame 12 with the plug 101 pointing downwards. Then, the pedal 7 is flipped so that the first hook 8 hooks onto the adjacent support rod 2 from above. If multiple sets of adjacent support components need to be spliced, they can be connected in this way.

[0027] Example 2

[0028] like Figures 1-3 As shown, this utility model proposes a prefabricated building scaffolding method. Compared to Embodiment 1, the support column 1 is equipped with a first locking member 5, which includes a first knob and a first screw. The first screw is inserted into the insertion hole 102 along the side of the support column 1 and is screwed to the support column 1. The first knob is connected to the outer end of the first screw, and the insertion hole 101 is provided with an annular groove. The distance between the annular groove and the lower end face of the support column 1 is the same as the distance between the first screw and the upper end face of the support column 1. A second locking member 14 is provided on the column cylinder 13. The second locking member 14 includes a second knob and a second screw. The second screw is inserted into the column cylinder 13 from the side and is screwed to it. The second screw is inserted into the annular groove, and the second knob is connected to the outer end of the second screw.

[0029] In this embodiment, during the process of inserting the support column 1 into the column cylinder 13 or splicing the upper and lower support columns 1, the first screw and the second screw are rotated by rotating the corresponding first knob and second knob, and then the screw is inserted into the annular groove on the plug 101 to achieve a fixed connection between the support columns 1 and the support columns 1 and the column cylinder 13.

[0030] Example 3

[0031] like Figure 1 and Figure 2 As shown, the scaffolding for prefabricated buildings proposed in this utility model, compared with Embodiment 1 and Embodiment 2, has a rotatable connecting plate 9 to the footboard 7. The two ends of the rotatable plate 9 are respectively connected to the second hook 10 and the third hook 11. The second hook 10 is connected to the support rod 2 where the fixing ring 6 is located. The first hook 8 and the third hook 11 are both hooked and engaged with the support rod 2 on the adjacent support assembly.

[0032] In this embodiment, after the pedal 7 is flipped to connect two adjacent support rods 2, the movable plate 9 is flipped so that the second hook 10 and the third hook 11 on the movable plate 9 are hooked to the support rods 2 on both sides respectively. Thus, the standing area during the operation is increased by splicing the movable plate 9 and the pedal 7.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
