DETAILED DESCRIPTION

[0021] Reference Figure 1-5 A scaffolding erection device for a construction project includes a stable base 1, a connecting base 2 is fixedly installed on one side of the stable base 1, and a steel column 4 is slidably installed on the inner side of the connecting base 2; a plurality of limiting grooves 11 are opened on the outer side of the steel column 4, and a limiting shell 3 is fixedly sleeved on the outer side of the connecting base 2; a flat threaded disk 15 is rotatably installed on the inner side of the limiting shell 3, and a plurality of sliding grooves are opened on the top of the connecting base 2.

[0022] In this embodiment, threaded sliders 16 are slidably installed on the inner sides of multiple sliding grooves, and multiple threaded sliders 16 are all threadedly connected to the same flat threaded disk 15, so that when the flat threaded disk 15 rotates, the multiple threaded sliders 16 are driven to move.

[0023] In this embodiment, a limiting metal block 17 is fixedly installed on one side of multiple threaded sliders 16, and the multiple limiting metal blocks 17 are respectively adapted to the corresponding limiting grooves 11, so that the multiple limiting metal blocks 17 can limit the steel column 4.

[0024] In this embodiment, a connecting ring 14 is fixedly installed on the top of the flat threaded disk 15, a rotating column 13 is fixedly installed on the top of the connecting ring 14, an anti-slip groove is provided on the outside of the rotating column 13, and a fixed ratchet 12 is fixedly installed on the top of the rotating column 13.

[0025] In this embodiment, threaded holes are provided on both sides of the limiting shell 3, and fixed shells 9 are fixedly installed on both sides of the limiting shell 3. Fixed grooves are provided on the tops of the two fixed shells 9, and supporting metal blocks 7 are slidably installed on the inner walls of both sides of the two fixed grooves.

[0026] In this embodiment, a support spring 8 is fixedly installed on one side of multiple supporting metal blocks 7, and one end of the multiple supporting springs 8 is respectively connected to the inner wall of one side of the corresponding fixing groove. A limiting ratchet 5 is provided on the sliding sleeve of the steel column 4, and a fixed metal bar 6 is fixedly installed on both sides of the limiting ratchet 5.

[0027] In this embodiment, the two fixing metal bars 6 are respectively adapted to the corresponding fixing grooves, and fixing holes are provided on one side of the two fixing metal bars 6 and the two fixing shells 9. The same threaded rod 10 is slidably installed in two fixing holes located on the same side among the multiple fixing holes, and the two threaded rods 10 are respectively adapted to the corresponding threaded holes, so that the corresponding fixing metal bars 6 can be limited by the two threaded rods 10.

[0028] Working principle: During assembly, the staff inserts the steel column 4 into the connecting base 2, and then after adjusting the position, the staff rotates the rotating column 13. The anti-skid grooves on the outside of the rotating column 13 help to prevent slipping, which can help the staff to better rotate the rotating column 13. The rotation of the rotating column 13 drives the connecting ring 14 to rotate, and the rotation of the connecting ring 14 drives the flat threaded disk 15 to rotate. Since multiple threaded sliders 16 are threadedly connected to the same flat threaded disk 15, the rotation of the flat threaded disk 15 drives multiple threaded sliders 16 to move, and the multiple threaded sliders 16 move close to the center of the flat threaded disk 15. The movement of multiple threaded sliders 16 drives the corresponding limiting metal blocks 17 to move, and the multiple limiting metal blocks 17 move and slide into the corresponding limiting grooves 11 opened on the surface of the steel column 4 to limit it. Then the staff puts the limiting ratchet 5 on the steel column 4 and slides it to the specified position. At this time, the limiting ratchet 5 and the rotating column When the fixing metal strips 6 slide into the fixing grooves, the two supporting metal blocks 7 are squeezed to make the corresponding two supporting metal blocks 7 slide inward. When the fixing metal strips 6 slide to the specified position, the two supporting metal blocks 7 are no longer affected by the squeezing force. The supporting metal blocks 7 are reset by the rebound force of the corresponding supporting springs 8 to limit the corresponding fixing metal strips 6. At this time, the staff passes the threaded rod 10 through the fixing holes on one side of the fixing housing 9 and the fixing metal strip 6. Two threaded holes are provided on the outside of the limiting housing 3. The threaded rod 10 is connected to the corresponding threaded holes to fix it and prevent the two fixing metal strips 6 from falling off, so that the limiting ratchet 5 can limit the fixing ratchet 12 more firmly.

[0029] The technical progress achieved by the present invention over the prior art is that the scaffold can be assembled quickly and conveniently through the provided mechanism, and it is convenient, quick and easy to use, which greatly improves work efficiency. In addition, the provided mechanism can effectively improve the stability of the scaffold connection, prevent loosening, and increase the safety of the device.
