Description

Technical Field

[0001] This invention relates to the field of scaffolding, specifically to a cantilevered scaffolding for the construction of super high-rise buildings. Background Technology

[0002] Scaffolding is a crucial auxiliary tool in the construction process. With continuous economic development, more and more urban buildings are becoming high-rises, and traditional ground-mounted scaffolding cannot meet construction demands. Therefore, cantilevered scaffolding is frequently used in high-rise building construction. Cantilevered scaffolding for super high-rise building construction is a specially designed type of scaffolding used to provide a support platform for workers performing tasks at height. This scaffolding system is typically designed to extend beyond the building's exterior and suspend at a high altitude to provide a working platform for construction, maintenance, and decoration tasks. Cantilevered scaffolding plays a critical role in the construction of super high-rise buildings, providing workers with the necessary high-altitude working platform and safety guarantees.

[0003] A search revealed patent number CN209585576U, which discloses a cantilever scaffold. This scaffold utilizes a first tie anchor and cantilever steel connecting the two ends of a wire rope to achieve an upward-pulling cantilever scaffold. This effectively prevents formwork bursting at the connection points of the exterior wall panels during concrete pouring. It is simple to operate, convenient and quick to construct, effectively improving construction quality and reducing later repair costs. However, existing cantilever scaffolds used in the construction of super high-rise buildings still have certain defects. The upper cantilever beam is prone to loosening between the cantilever beam and the floor slab due to worker movement or the accumulation of heavy objects, thus reducing the stability of the cantilever scaffold and posing a risk to worker safety. Therefore, this paper proposes a cantilever scaffold for the construction of super high-rise buildings. Summary of the Invention

Next, two sets of second anchor rods pass through the first cantilever beam and are secured to the lower floor slab. Then, two sets of third anchor rods pass through two sets of fixing plates and are secured to the lower floor slab. Finally, by adjusting the vertical screw rods, connecting screw holes, and internal thread retaining rings, and cooperating with the threaded internal thread pipe and fastening screw rods, the bottom support plate is made to fit tightly against the lower surface of the lower floor slab.

Then, rotate the rotating handle in the middle of the transverse groove shell to drive the two sets of adjusting transverse screws that pass through the transverse groove shell to rotate. In this way, with the cooperation of the symmetrical external threads and thread grooves, the first connecting column and the second connecting column are driven to move relatively away along the inner side of the transverse groove shell. This allows the two sets of first cantilever beams to move relatively on the upper surface of the lower floor slab, which can stably change the length of the cantilever scaffolding.

An internal threaded pipe 23 is fixedly connected to the lower surface of each of the two sets of second cantilever beams 10 away from the adjusting vertical screw 19. A fastening screw 22 is installed through the lower surface of each of the two sets of bottom support plates 18 near the middle position.

The two sets of adjusting vertical screws 19 are threaded to the two sets of bottom support plates 18 through the connecting screw hole 20 respectively, and the two sets of adjusting vertical screws 19 are threaded to the two sets of internal threaded retaining rings 21 respectively.

[0033] Two sets of bottom support plates 18 are fixedly connected to the upper surface near the middle position with second connecting plates 24. Four anchor rods 25 are installed through the outer side of the two sets of second connecting plates 24 near both ends. All four sets of fourth anchor rods 25 are engaged with the lower floor slab 1.

[0034] Specifically, the first cantilever beam 3 and the second cantilever beam 10 are initially connected by two sets of limiting slide plates 13. Then, the second cantilever beam 10 is secured to the lower side of the first cantilever beam 3 by two sets of fastening bolts 15. Next, two sets of second anchor rods 14 are passed through the first cantilever beam 3 and secured to the lower floor slab 1.

Finally, two sets of fourth anchor rods 25 are passed through the second connecting plate 24 and secured to the lower floor slab 1. This can prevent the connection between the cantilever scaffold and the lower floor slab 1 from becoming loose during use, thus improving the stability and safety of the cantilever scaffold.

[0035] As one embodiment of the present invention, refer to Figure 4 Both sets of first cantilever beams 3 are equipped with first vertical poles 26 on their upper sides, and both sets of second cantilever beams 10 are equipped with second vertical poles 27 on their upper sides. The upper ends of both sets of first vertical poles 26 and second vertical poles 27 are fixedly connected to baffles 39. The lower ends of both sets of first vertical poles 26 and second vertical poles 27 are provided with bottom threaded grooves 28. The upper surfaces of both sets of first cantilever beams 3 are fixedly connected to first fixing screws 29 near the middle position. The upper sides of both sets of second cantilever beams 10 are fixedly connected to second fixing screws 30. Several sets of first connecting blocks 31 are sleeved on the outer sides of both sets of first vertical poles 26. Several sets of second connecting blocks 32 are sleeved on the outer side of the rod 27. A first horizontal rod 35 is provided through the first connecting block 31 and the second connecting block 32.

A through hole 38 is provided through the several sets of first fixing blocks 36 and the several sets of second fixing blocks 37.

[0036] The first connecting block 31 and the second connecting block 32 are respectively threaded to the first vertical rod 26 and the second vertical rod 27 through the first screw hole 33, and the first connecting block 31 and the second connecting block 32 are respectively threaded to the first horizontal rod 35 through the second screw hole 34. The first fixing block 36 and the second fixing block 37 are respectively slidably connected to the second horizontal rod 43 through the through hole 38. The first horizontal rod 35 and the second horizontal rod 43 are arranged perpendicular to each other. The two sets of first vertical rods 26 and the two sets of second vertical rods 27 are respectively threaded to the two sets of first fixing screws 29 and the two sets of second fixing screws 30 through the bottom screw groove 28.

[0037] Specifically, two sets of first fixing screws 29 and two sets of second fixing screws 30, in conjunction with the bottom screw groove 28, secure two sets of first vertical poles 26 and two sets of second vertical poles 27 to the upper sides of two sets of first cantilever beams 3 and two sets of second cantilever beams 10, respectively. At this time, several sets of first connecting blocks 31 and several sets of second connecting blocks 32 are threadedly connected to the outer sides of the two sets of first vertical poles 26 and two sets of second vertical poles 27 through the first screw holes 33 at equal intervals. Then, through two sets of second screw holes 34, the first horizontal bar 35 is threaded between the first connecting block 31 and the second connecting block 32, and through the through hole 38, the second horizontal bar 43 is installed between the two sets of first fixing blocks 36 and between the two sets of second fixing blocks 37. This has a highly efficient combination installation function, reduces the installation difficulty of cantilever scaffolding, and significantly improves the disassembly and assembly efficiency of cantilever scaffolding.

[0038] As one embodiment of the present invention, refer to Figure 4 A transverse groove shell 7 is provided between the two sets of first cantilever beams 3. A first connecting plate 11 is fixedly connected to the bottom of one side of the transverse groove shell 7. First anchor rods 12 are provided through the upper surface of the first connecting plate 11 near both ends. A first connecting column 4 and a second connecting column 5 are fixedly connected to the middle of the opposite surfaces of the two sets of first cantilever beams 3, respectively. Threaded grooves 6 are opened at the opposite ends of the first connecting column 4 and the second connecting column 5. A rotating handle 8 is provided in the middle of the transverse groove shell 7. Adjusting transverse screws 9 that penetrate the transverse groove shell 7 are fixedly connected to the middle of both sides of the rotating handle 8. The two sets of second cantilever beams 10 The upper surface is fixedly connected with connecting steel cables 40. The upper ends of the two sets of connecting steel cables 40 are fixedly connected with upper plates 41. Top anchor rods 42 are installed through the outer sides of the two sets of upper plates 41. The two sets of first anchor rods 12 pass through the first connecting plate 11 and are engaged with the lower floor slab 1. The external threads of the two sets of adjusting horizontal screw rods 9 are symmetrically arranged. The first connecting column 4 and the second connecting column 5 are threadedly connected to the two sets of adjusting horizontal screw rods 9 through the threaded groove 6. The first connecting column 4 and the second connecting column 5 are slidably connected to the horizontal groove shell 7. The two sets of top anchor rods 42 pass through the upper plates 41 and are engaged with the upper floor slab 2.

[0039] Specifically, the two sets of first anchor rods 12 are respectively passed through the first connecting plate 11 and engaged with the lower floor slab 1, so that the transverse groove shell 7 is fixedly installed at the edge of the upper surface of the lower floor slab 1. Then, the rotating handle 8 in the middle of the transverse groove shell 7 is rotated to drive the two sets of adjusting transverse screws 9 that pass through the transverse groove shell 7 to rotate. Thus, with the cooperation of the symmetrical external threads and threaded grooves 6, the first connecting column 4 and the second connecting column 5 are driven to move relatively away along the inner side of the transverse groove shell 7, thereby causing the two sets of first cantilever beams 3 to move relatively on the upper surface of the lower floor slab 1. This can stably change the length of the cantilever scaffolding, has a convenient length adjustment function, and improves the applicability of the cantilever scaffolding.

[0040] Working principle: First, the workers insert the two sets of first anchor rods 12 through the first connecting plate 11 and engage them with the lower floor slab 1, so that the transverse groove shell 7 is securely installed at the edge of the upper surface of the lower floor slab 1. Then, the rotating handle 8 in the middle of the transverse groove shell 7 is rotated to drive the two sets of adjusting transverse screws 9 that pass through the transverse groove shell 7 to rotate. Thus, with the cooperation of the symmetrical external threads and threaded grooves 6, the first connecting column 4 and the second connecting column 5 move relatively away from each other along the inner side of the transverse groove shell 7, thereby causing the two sets of first cantilever beams 3 to move relatively on the upper surface of the lower floor slab 1. This allows for stable changes in the length of the cantilever scaffolding and provides convenient length adjustment. The overall function improves the applicability of cantilever scaffolding. Secondly, two sets of limiting slide plates 13 initially connect the first cantilever beam 3 and the second cantilever beam 10. Then, two sets of fastening bolts 15 secure the second cantilever beam 10 to the underside of the first cantilever beam 3. Next, two sets of second anchor rods 14 pass through the first cantilever beam 3 and are secured to the lower floor slab 1. Then, two sets of third anchor rods 17 pass through two sets of fixing plates 16 and are secured to the lower floor slab 1. Finally, by adjusting the vertical screw rod 19, connecting screw hole 20, and internal thread retaining ring 21, and engaging the threaded internal thread pipe 23 and fastening screw rod 22, the bottom support plate 18 is tightly fitted to the lower surface of the lower floor slab 1. Two sets of fourth anchor rods 25 pass through the second connecting plate 24 and are engaged with the lower floor slab 1, which can prevent the connection between the cantilever scaffold and the lower floor slab 1 from becoming loose during use, thus improving the stability and safety of the cantilever scaffold. Finally, two sets of first fixing screws 29 and two sets of second fixing screws 30, together with the bottom screw groove 28, secure the two sets of first vertical poles 26 and two sets of second vertical poles 27 to the upper side of the two sets of first cantilever beams 3 and two sets of second cantilever beams 10, respectively. At this time, several sets of first connecting blocks 31 and several sets of second connecting blocks 32 are threadedly connected to the two sets of first vertical poles through the first screw holes 33 at equal intervals. On the outside of 26 and two sets of second vertical poles 27, the first horizontal pole 35 is threaded between the first connecting block 31 and the second connecting block 32 through two sets of second screw holes 34, and the second horizontal pole 43 is installed between two sets of first fixing blocks 36 and two sets of second fixing blocks 37 through through holes 38. It has an efficient combination installation function, reduces the installation difficulty of cantilever scaffolding, and significantly improves the disassembly and assembly efficiency of cantilever scaffolding. Then, the connecting steel cable 40 is inclinedly connected between the upper floor slab 2 and the second cantilever beam 10 through the top anchor rod 42 on the upper plate 41 to further improve the support stability of the cantilever scaffolding and complete the operation.
