Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, it relates to a temporary scaffolding device for building construction. Background Technology

[0002] In modern construction, temporary scaffolding is an important auxiliary facility to ensure the safety of construction workers and improve work efficiency. However, most of the scaffolding commonly found on the market currently uses traditional bolt fixing or clip connection methods. This connection method not only requires the use of professional tools, but also has a cumbersome and time-consuming operation process. In large-scale construction projects, the installation and dismantling of a large number of scaffolding often consumes a lot of manpower and time resources, which seriously affects the construction progress.

[0003] In complex and ever-changing construction site environments, the traditional scaffolding assembly and disassembly process is increasingly inadequate. Due to the suboptimal design of the connection structure, construction workers need to frequently change tools and adjust positions when working at heights. This not only increases the difficulty of the work but also easily leads to safety hazards due to improper operation. Utility Model Content

[0029] Please see Figures 1-5 A temporary scaffolding device for building construction includes a top plate 1. A splicing mechanism is installed below the top plate 1. The splicing mechanism includes upper columns 2, insert sleeves 3, quick-connect sleeves 4, lower columns 5, snap-fit ​​pieces 6, slots 7, push blocks 8, return springs 9, abutment sleeves 10, and a quick-release mechanism. Multiple sets of upper columns 2 are installed on the bottom surface of the top plate 1. Insert sleeves 3 are installed at the bottom ends of multiple sets of upper columns 2, with the insert sleeves 3 positioned on the outer side of the multiple sets of insert sleeves 3. Lower columns 5 are installed at the bottom ends of multiple sets of quick-connect sleeves 4. Multiple sets of snap-fit ​​pieces 6 are distributed inside the quick-connect sleeves 4, and slots 7 are positioned outside the insert sleeves 3. On the side, the push block 8 is provided with multiple sets sliding on the outer wall of the quick-connect sleeve 4, the return spring 9 is provided with multiple sets installed on the outer side of the quick-connect sleeve 4, and the abutment sleeve 10 is installed on the top of the multiple sets of return springs 9 and abuts against the top of the multiple sets of push blocks 8. The quick-release mechanism includes a slide groove 11, a slide sleeve 12, a push sleeve 13, a push plate 14 and an unlocking sleeve 15. The slide groove 11 is provided with multiple sets distributed on the outer wall of the quick-connect sleeve 4, the slide sleeve 12 slides in the multiple sets of slide grooves 11, the push sleeve 13 is installed on the bottom surface of the slide sleeve 12, the push plate 14 is provided with multiple sets installed on the top surface of the slide sleeve 12, and the unlocking sleeve 15 is installed on the inner side of the slide sleeve 12.

[0030] The quick-connect sleeve 4 is provided with a limiting mechanism on its outer side. The limiting mechanism includes a slide rod 16, a limiting sleeve 17, an arc groove 18, a clearance groove 19, and a stop block 20. Multiple sets of slide rods 16 are distributed on the top surface of the push sleeve 13. The limiting sleeve 17 is rotatably installed on the outer wall of the quick-connect sleeve 4. Multiple sets of arc grooves 18 are distributed on the limiting sleeve 17. The clearance groove 19 is located at one end of the multiple sets of arc grooves 18. The stop block 20 is located at the top of the multiple sets of slide rods 16.

[0031] Each of the multiple push blocks 8 has a reset spring 21 connected to its top end, and the bottom of each of the multiple reset springs 21 is fixedly connected to the outer wall of the quick-connect sleeve 4. The reset spring 21 provides an inward reset force to the push block 8, ensuring that the push block 8 can automatically return to its initial position.

[0032] A compression spring 22 is installed inside the sleeve 3. An abutment rod 23 is connected to the top of the compression spring 22. The abutment rod 23 is slidably connected to the sleeve 3. The compression spring 22 provides a buffering force to the sleeve 3 through the abutment rod 23, making the connection process more stable.

[0033] The outer wall of the insert sleeve 3 is provided with a positioning groove 24, and multiple sets of positioning grooves 24 are provided. The inner wall of the quick-connect sleeve 4 is provided with a positioning plate 25, and multiple sets of positioning plates 25 are provided and are slidably connected to multiple sets of positioning grooves 24 respectively. The positioning plate 25 slides in the positioning groove 24 to provide accurate positioning guidance for the insert sleeve 3 and the quick-connect sleeve 4.

[0034] A push spring 26 is installed on the bottom surface of the limiting sleeve 17, and a thrust bearing 27 is connected to the top of the push spring 26. The thrust bearing 27 is slidably connected to the push sleeve 13. The push spring 26 provides elastic support to the push sleeve 13 through the thrust bearing 27, while reducing rotational friction.

[0035] The two ends of the multiple push blocks 8 are all set to be arc-shaped. The arc-shaped design of the push blocks 8 reduces the contact resistance with other components, making the movement smoother.

[0036] Support rods 28 are connected between multiple sets of upper columns 2 and lower columns 5. There are multiple sets of support rods 28. Railings 29 are installed on both sides of the top plate 1. The support rods 28 provide lateral support for the columns, while the railings 29 provide safety protection.

[0037] In this embodiment, when splicing is required, rotating the limiting sleeve 17 causes multiple sets of sliding rods 16 to slide along the arc-shaped groove 18 into the clearance groove 19, thereby releasing multiple sets of stops 20 from contact with the outer wall of the limiting sleeve 17, releasing the restriction of the push sleeve 13, and pushing the push sleeve 13 and the sliding sleeve 12 through the push spring 26, causing the sliding sleeve 12 to slide along the sliding groove 11 and push the unlocking sleeve 15 to abut against multiple sets of snap-fit ​​pieces 6. At the same time, the sliding sleeve 12 pushes the abutting sleeve 1 through multiple sets of push plates 14. 0 releases the contact of multiple sets of push blocks 8 and compresses the return spring 9. The elastic return of multiple sets of return springs 21 pulls the push blocks 8 outward to release the contact of multiple sets of locking pieces 6. The unlocking sleeve 15 pushes the multiple sets of locking pieces 6 to rotate outward to make room for the insert sleeve 3, inserting the insert sleeve 3 into the quick-connect sleeve 4. The multiple sets of positioning plates 25 and positioning grooves 24 are used for positioning and insertion. The insert sleeve 3 drives the abutment rod 23 to abut against the lower column 5 and compress the compression spring 22. When the insert sleeve When the 3rd set of contact sleeve 4 is pressed against the inner top surface, the slot 7 moves to the inner side of the multiple sets of contact pieces 6, pulling the push sleeve 13 and the sliding sleeve 12 to slide, so that the slide rod 16 moves into the relief groove 19. At this time, the multiple sets of push plates 14 release the pressure on the abutting sleeve 10. Through the elastic reset of the multiple sets of return springs 9, the abutting sleeve 10 is pushed against the top of the multiple sets of push blocks 8 and squeezes the multiple sets of return springs 21, so that the multiple sets of push blocks 8 are pressed against the outer side of the multiple sets of contact pieces 6, thereby pushing the multiple sets of contact pieces 6 to engage. Within the slot 7, the limiting sleeve 17 is rotated to allow multiple sets of sliding rods 16 to slide within the arc-shaped groove 18, and multiple sets of stop blocks 20 abut against the top surface of the limiting sleeve 17 to limit the push sleeve 13. Conversely, when disassembly is required, the pre-operation before installation is repeated to release the multiple sets of snap-fit ​​pieces 6 from the slot 7, and then the elastic reset of the compression spring 22 pushes the abutment block to apply a reverse thrust to the insert sleeve 3, causing it to disengage from the quick-connect sleeve 4, thus completing the disassembly of the insert sleeve 3 and the quick-connect sleeve 4.

[0038] In summary, during the use or operation of the overall equipment: when splicing is required, rotating the limiting sleeve 17 causes multiple sets of sliding rods 16 to slide along the arc-shaped groove 18 into the clearance groove 19, thereby releasing multiple sets of stops 20 from contact with the outer wall of the limiting sleeve 17, releasing the restriction of the push sleeve 13, and pushing the push sleeve 13 and sliding sleeve 12 through the push spring 26, causing the sliding sleeve 12 to slide along the slide groove 11 and push the unlocking sleeve 15 to abut against multiple sets of snap-fit ​​pieces 6. At the same time, the sliding sleeve 12 is pushed by multiple sets of push plates 14. The push sleeve 10 releases the contact with the multiple sets of push blocks 8 and compresses the return spring 9. The elastic return of the multiple sets of return springs 21 pulls the push blocks 8 outward to release the contact with the multiple sets of locking pieces 6. The unlocking sleeve 15 pushes the multiple sets of locking pieces 6 outward to make room for the insert sleeve 3, inserting the insert sleeve 3 into the quick-connect sleeve 4. The multiple sets of positioning plates 25 are positioned and inserted into the positioning groove 24. The insert sleeve 3 drives the abutment rod 23 to abut against the lower column 5 and compress the compression spring 22. When the insert 3 abuts against the inner top surface of the quick-connect sleeve 4, the slot 7 moves to the inner side of the multiple sets of locking pieces 6, pulling the push sleeve 13 and the sliding sleeve 12 to slide, causing the slide rod 16 to move into the relief groove 19. At this time, the multiple sets of push plates 14 release their pressure on the abutting sleeve 10, and the elastic reset of the multiple sets of return springs 9 pushes the abutting sleeve 10 against the top of the multiple sets of push blocks 8 and squeezes the multiple sets of return springs 21, causing the multiple sets of push blocks 8 to abut against the outer side of the multiple sets of locking pieces 6, thereby pushing the multiple sets of locking pieces 6. The sleeve 13 is engaged in the slot 7, and then the limiting sleeve 17 is rotated so that multiple sets of sliding rods 16 slide in the arc groove 18 and abut against the top surface of the limiting sleeve 17 by multiple sets of stop blocks 20, thus limiting the push sleeve 13. Conversely, when disassembly is required, the pre-operation before installation is repeated to release the engagement of multiple sets of snap-fit ​​pieces 6 with the slot 7, and then the elastic reset of the compression spring 22 pushes the abutment block to apply a reverse thrust to the insert sleeve 3 so that it disengages from the quick-connect sleeve 4, thus completing the disassembly of the insert sleeve 3 and the quick-connect sleeve 4.

For all the fixed connections mentioned above, welding is preferred.
