Abstract

This utility model discloses a disc-lock type scaffolding, relating to the field of scaffolding. The utility model includes four bases and multiple crossbars. Each of the four bases has a stud welded to its top, and the outer wall of the stud is threaded with an adjusting nut. A vertical pole is fitted onto the top of the stud. This utility model incorporates a pin, anti-slip plate, slot, locking plate, slide block, spring, and push block. After the hook is hung on the corresponding crossbar, the worker first pushes the push block, which moves the slide block. The slide block then compresses the spring and moves the locking plate. Next, the anti-slip plate is rotated, causing its inner wall to fit against the outer wall of the crossbar, and the locking plate rotates into the slot. Then, the push block is pushed in the opposite direction, and the spring stretches, causing the slide block to return to its original position. When the locking plate is fully engaged in the slot, the anti-slip plate is locked in place. The anti-slip plate and hook form a ring-shaped engagement on the crossbar, increasing friction and improving the stability of the hook and footboard.

Description

Technical Field

[0001] This utility model relates to the field of scaffolding, specifically a disc-lock scaffolding. Background Technology

[0002] Currently, cup-lock scaffolding and disc-lock scaffolding are mainly used in building construction, road and bridge construction, and shipbuilding. Among them, cup-lock scaffolding is gradually being phased out due to safety issues, while disc-lock scaffolding is becoming increasingly widely used. The conventional method of assembling disc-lock scaffolding is as follows: first, the couplings at the ends of the horizontal bars are snapped onto the connecting plates, and then pins are used to connect the couplings and the connecting plates together to assemble the scaffolding.

[0003] Existing disc-lock scaffolding typically consists of an adjustable base, uprights, horizontal bars, diagonal braces, discs, and footboards. Hooks are welded to both sides of the footboards. When installing the footboards, workers hang them on the horizontal bars using these hooks. However, the contact area between the hooks and the horizontal bars is small, resulting in insufficient friction. When subjected to external forces (such as workers walking or tools colliding) or vibrations, the hooks are prone to slipping along the horizontal bars, directly affecting the stability of the footboards. In severe cases, the footboards may even lift up, posing a significant safety hazard to workers. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a disc-lock scaffold to solve the technical problem that when footboards are hung on horizontal bars by hooks, the hooks may slip, thus affecting the stability of the footboards.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a disc-lock scaffold, comprising four bases and multiple crossbars. Each of the four bases has a stud welded to its top, and an adjusting nut is threaded onto the outer wall of the stud. A vertical rod is fitted onto the top of each stud. Two hooks are hung on the outer walls of each of the two crossbars. Foot pedals are installed between the four hooks. An anti-slip plate is rotatably connected to one side of the bottom of each hook via a pin. A groove is formed on one side of the top of the anti-slip plate, and a push groove communicating with the groove is formed on the outer surface of the anti-slip plate. A sliding seat is provided inside the groove, and a locking plate is fixed to the top of the sliding seat. Installation grooves are formed on one side of the sliding seat and one side of the groove. A spring is installed between every two installation grooves. A locking groove is formed on the other side of the bottom of each hook. A push seat extending through the push groove is installed on the outer surface of the sliding seat.

[0006] By adopting the above technical solution, the foot pedal can be installed after the hook on the foot pedal is hung on the crossbar, making it convenient for construction workers to stand on the foot pedal to carry out construction work.

[0007] Furthermore, a baffle is installed on one side of the push base. The size of the baffle is larger than the size of the push groove, and the back of the baffle is in contact with the outer surface of the anti-slip plate.

[0008] By adopting the above technical solution, the baffle can block the push groove and prevent external impurities from entering the slide groove through the push groove.

[0009] Furthermore, the card plate is located inside the card slot, and the card plate is in the shape of an inverted "L".

[0010] By adopting the above technical solution, once the card plate is inserted into the slot, the stability of the anti-slip plate can be improved, preventing the anti-slip plate from rotating and opening at will.

[0011] Furthermore, an anti-slip pad is installed on the outer wall of the card plate. The anti-slip pad is made of silicone rubber material, and the outer wall of the anti-slip pad is in contact with the inner wall of the card slot.

[0012] By adopting the above technical solution, the anti-slip pad can improve the stability of the card plate, prevent the card plate from moving at will, and make the card plate securely locked inside the card slot.

[0013] Furthermore, both the inner wall of the anti-slip plate and the inner wall of the hook are provided with anti-slip texture.

[0014] By adopting the above technical solution, the anti-slip texture can improve the stability of the hook hanging on the crossbar.

[0015] Furthermore, the outer walls of the four uprights are all welded with discs, and the discs have multiple slots, with a crossbar inserted between every two discs.

[0016] By adopting the above technical solution, the disc is designed to facilitate the locking of the crossbar.

[0017] Furthermore, a through groove is provided on the part where the crossbar and the disc engage, and a pin is inserted into one of the slots and the through groove.

[0018] By adopting the above technical solution, when the pin is inserted into the slot and through groove, the crossbar can be locked and limited to prevent it from moving at will, thereby improving the stability of the crossbar.

[0019] Furthermore, diagonal braces are installed between the two horizontal bars located directly in front and between the two horizontal bars located behind.

[0020] By adopting the above technical solutions, the installation of diagonal braces can distribute the load on the scaffolding more evenly to each upright, preventing local uprights from becoming unstable and failing due to excessive load.

[0021] Furthermore, the top of the adjusting nut contacts the bottom end of the upright.

[0022] By adopting the above technical solution, the adjusting nut can provide support for the upright.

[0023] Furthermore, the card plate is slidably connected to the slide groove via a slide block, and the push block is slidably connected to the push groove.

[0024] By adopting the above technical solution, when the pusher slides inside the push groove, the pusher will drive the slide block to slide inside the slide groove, and the slide block will drive the card plate to move.

[0025] In summary, the present invention has the following main advantages:

[0026] 1. This utility model is equipped with a pin, anti-slip plate, slot, clamping plate, slide groove, slide seat, spring, and push seat. After the hook is hung on the corresponding crossbar, the construction personnel can first push the push seat, which drives the slide seat to move. The slide seat then compresses the spring and drives the clamping plate to move. Then, the anti-slip plate is rotated so that the inner wall of the anti-slip plate fits against the outer wall of the crossbar. At this time, the clamping plate will rotate into the slot. Then, the push seat is pushed in the opposite direction, and the spring stretches to drive the slide seat to return to its original position. When the clamping plate is inserted into the deepest part of the slot, the anti-slip plate is limited, preventing it from rotating and opening at will. The anti-slip plate and the hook form a ring that is clamped on the crossbar, thereby increasing the contact area with the crossbar and increasing the friction between them, preventing the hook from sliding at will, thus improving the stability of the hook and foot pedal, and preventing the foot pedal from tilting up, improving the safety of the foot pedal during use.

[0027] 2. This utility model improves the stability of the card plate by providing an anti-slip pad, the outer wall of which fits against the inner wall of the card slot, preventing the card plate from moving randomly and ensuring that the card plate is securely locked inside the card slot. The baffle can block the push groove and prevent external impurities from entering the sliding groove through the push groove. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] Example 1:

[0039] A type of modular scaffolding, such as Figures 1-7 As shown, it includes four bases 1 and multiple crossbars 7. Each of the four bases 1 has a stud 2 welded to its top, and an adjusting nut 3 is threaded onto the outer wall of the stud 2. A vertical rod 4 is fitted onto the top of each stud 2. Each of the four vertical rods 4 has a disc 5 welded to its outer wall, and multiple slots 6 are formed on the discs 5. A crossbar 7 is engaged between every two discs 5. The discs 5 are designed to facilitate engaging the crossbar 7. A through groove is formed at the engagement point between the crossbar 7 and the disc 5. A pin 8 is inserted into one of the slots 6 and the through groove. When the crossbar 7 is engaged with the disc 5... After the pin 8 is inserted into the slot 6 and the through groove, the horizontal bar 7 can be locked and limited to prevent it from moving at will, thus improving its stability. Diagonal bars 9 are installed between the two horizontal bars 7 at the front and between the two horizontal bars 7 at the rear. The diagonal bars 9 can distribute the load on the scaffolding more evenly to each upright, preventing local uprights from becoming unstable and damaged due to excessive load. The top of the adjusting nut 3 contacts the bottom of the upright 4, and the adjusting nut 3 can provide support for the upright 4.

[0040] See Figures 1-5, two hooks 11 are respectively hung on the outer walls of the two crossbars 7. A footrest 10 is installed between the four hooks 11. Anti-slip bumps are provided on the top of the footrest 10. One side of the bottom of the hook 11 is rotatably connected to an anti-slip plate 13 through a pin shaft 12. A chute 18 is provided on one side of the top of the anti-slip plate 13. A push groove 24 communicating with the chute 18 is provided on the outer surface of the anti-slip plate 13. A sliding seat 19 is arranged inside the chute 18. A clamping plate 16 is fixed on the top of the sliding seat 19. Installation grooves 21 are provided on one side of the sliding seat 19 and one side of the inner part of the chute 18. A spring 20 is installed between every two installation grooves 21. The spring 20 is made of high-strength alloy spring steel material. A clamping groove 15 is provided on the other side of the bottom of the hook 11. A push seat 23 penetrating outside the push groove 24 is installed on the outer surface of the sliding seat 19. After hanging the hook 11 on the footrest 10 on the crossbar 7, the installation of the footrest 10 can be completed, which is convenient for construction workers to stand on the footrest 10 for construction operations.

[0041] Specifically, the clamping plate 16 is located inside the clamping groove 15. The clamping plate 16 is in an inverted "L" shape. After the clamping plate 16 is clamped into the clamping groove 15, the stability of the anti-slip plate 13 can be improved, preventing the anti-slip plate 13 from rotating and opening randomly. Anti-slip patterns 14 are provided on the inner walls of the anti-slip plate 13 and the hook 11. The anti-slip patterns 14 can improve the stability of the hook 11 hanging on the crossbar 7. The clamping plate 16 is slidably connected to the chute 18 through the sliding seat 19. The sliding seat 19 is in a "convex" shape. The push seat 23 is slidably connected to the push groove 24. When the push seat 23 slides inside the push groove 24, the push seat 23 will drive the sliding seat 19 to slide inside the chute 18, and the sliding seat 19 will drive the clamping plate 16 to move.

[0042] Embodiment Two:

[0043] On the basis of the above Embodiment One, in order to prevent external impurities from entering the inside of the chute 18 through the push groove 24, the push groove 24 needs to be blocked, so the following structure will be set.

[0044] Refer to Figures 4-7 , a baffle 22 is installed on one side of the push seat 23. The size of the baffle 22 is larger than the size of the push groove 24. The back of the baffle 22 is fitted with the outer surface of the anti-slip plate 13. The baffle 22 can block the push groove 24 to prevent external impurities from entering the inside of the chute 18 through the push groove 24.

[0045] Embodiment Three:

[0046] On the basis of the above Embodiment One, in order to improve the stability of the clamping plate 16, the following structure will be set.

[0047] Specifically, the outer wall of the card plate 16 is equipped with an anti-slip pad 17, which is made of silicone rubber. The outer wall of the anti-slip pad 17 is in contact with the inner wall of the card slot 15. The anti-slip pad 17 can improve the stability of the card plate 16, prevent the card plate 16 from moving at will, and make the card plate 16 securely stuck inside the card slot 15.

[0048] The working principle of this utility model is as follows: First, four bases 1 support the uprights 4 through studs 2 welded to the top. The adjusting nut 3 on the outer wall of the stud contacts the bottom end of the upright 4. By rotating the adjusting nut 3, the height of the upright 4 can be adjusted to ensure the overall level of the scaffolding. The two ends of the horizontal bar 7 are locked between the discs 5 of the adjacent uprights 4. A through groove is opened at the locking part of the horizontal bar 7 and the disc 5. The pin 8 is inserted into the slot 6 and the through groove to achieve a rigid connection between the horizontal bar 7 and the upright 4, preventing the horizontal bar 7 from shifting. The foot pedal 10 is hung on the two horizontal bars 7 through four hooks 11. Then, the construction workers can first push the push seat 23, and the push seat 2... 3 drives the slide 19 to move, which in turn squeezes the spring 20 and drives the locking plate 16 to move. Then, the anti-slip plate 13 is rotated so that the inner wall of the anti-slip plate 13 fits against the outer wall of the crossbar 7. At this time, the locking plate 16 will rotate into the slot 15. Then, the pusher 23 is pushed in the opposite direction, and the spring 20 stretches to drive the slide 19 to reset and move. When the locking plate 16 is inserted into the deepest part of the slot 15, the anti-slip plate 13 can be limited to prevent it from rotating and opening at will. The anti-slip plate 13 and the hook 11 form a ring and are locked on the crossbar 7, which can increase the friction between them and the crossbar 7 and prevent the hook 11 from sliding at will.
