Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an adjustable scaffold. Background Technology

[0002] Construction is a production activity in the implementation phase of engineering construction. It is the process of building various types of buildings. The place where construction work is carried out is called the construction site or construction site. Adjustable scaffolding is required during construction.

[0003] A search revealed Chinese patent CN216239640U, which discloses a height-adjustable scaffolding, comprising two sets of support frames and a platform tread. Multiple sets of first support blocks are fixedly mounted on the top of each of the two sets of support frames, arranged vertically at intervals. These first support blocks are aligned and flush with each other. Connecting blocks are fixedly mounted on opposite sides of the platform tread. The two sets of connecting blocks are detachably installed on the corresponding, flush first support blocks. This application enables height adjustment of the scaffolding while minimizing its impact on stability, facilitating the installation or maintenance of parts at specific heights.

[0004] Based on the above search results combined with existing technologies, the findings were as follows:

[0005] The aforementioned search patent platform has limitations in that the fixation between the pedal and the support frame is not secure, the load-bearing capacity is limited, there are certain safety hazards, and it is difficult to move and prone to damage, which increases construction costs and reduces construction efficiency. Utility Model Content

[0026] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0027] This utility model provides an adjustable scaffolding through improvements. The technical solution of this utility model is as follows:

[0028] like Figures 1-4 As shown, an adjustable scaffold includes a support frame 1 and a platform tread 2. The platform tread 2 is fixedly installed inside the support frame 1 to improve the load-bearing capacity of the platform tread 2 and provide safety for workers during later construction. It also includes:

[0029] The fixed frame 3 is fixedly installed on both sides of the lower end of the platform pedal 2. The inner side wall of the fixed frame 3 is movably connected to the first insert plate 4, and the first insert plate 4 passes through the support frame 1, which provides a good auxiliary role in enhancing the stability of the device.

[0030] The fixing plate 14 is fixedly installed on both sides of the support frame 1. The second threaded post 15 is fixedly installed between the fixing plates 14. The second threaded post 15 is set between the support frames 1, which can achieve quick adjustment and installation, shorten the construction preparation time, and improve the overall efficiency.

[0031] Furthermore, a second insert plate 5 is provided at the bottom of the platform pedal 2, and the two ends of the second insert plate 5 pass through the fixing frame 3. A first mounting plate 6 is installed on both sides of the platform pedal 2. A rotating block 7 is movably installed inside the first mounting plate 6. A rotating column 10 is provided through the upper end of the first mounting plate 6, and the rotating column 10 passes through the rotating block 7. A first threaded column 8 is fixedly installed at one end of the rotating block 7. A first nut 9 is sleeved on the outside of the first threaded column 8. The height can be adjusted according to the needs to adapt to different construction environments, especially suitable for places where the height changes frequently.

[0032] Furthermore, a ladder 13 is installed on the right side wall of the platform step 2, and multiple sets of first slots 11 are opened on the inner side wall of the support frame 1, and multiple sets of second slots 12 are opened on the outer side wall of the support frame 1, which facilitates the connection to the outside of the building and reduces safety hazards.

[0033] As a further embodiment of this utility model, a second nut 16 is installed on the external thread of the second threaded post 15, a support plate 17 is fixedly installed near the bottom of the support frame 1, and a first friction box 18 and a second friction box 19 are respectively installed on both sides of the bottom of the support frame 1. Through the first friction box 18 and the second friction box 19, the contact area between the adjustable scaffold and the ground is increased, thereby enhancing the stability of the adjustable scaffold.

[0034] Furthermore, a base plate 20 is fixedly installed on the inner sidewall of both the first friction box 18 and the second friction box 19. A second mounting plate 21 is installed at the bottom of the first friction box 18 and the second friction box 19. A moving wheel 22 is provided on one side of the second mounting plate 21 to adjust the construction position. It can be reused, reducing material waste and having a low long-term use cost.

[0035] Furthermore, a third threaded post 23 is installed through the first friction box 18 and the second friction box 19. One end of the third threaded post 23 is threadedly connected to a third nut 24. A third slot 25 is opened on one side of both the first friction box 18 and the second friction box 19. A clamping post 26 is fixedly installed on the surface of the base plate 20. The structure is stable, has a strong load-bearing capacity, and reduces construction risks.

[0036] The specific working method is as follows: First, rotate the first nut 9 to remove the restriction on the first threaded post 8. Then, pull the first threaded post 8, causing it to drive the rotating block 7 to rotate through the rotating post 10 in the first mounting plate 6. At this point, the fixation between the platform pedal 2 and the support frame 1 disappears. Remove the platform pedal 2, then take out the first insert plate 4 and insert it into the first slot 11 at the required height. Next, place the platform pedal 2 above the first insert plate 4, so that the fixing frame 3 is secured to the first insert plate 4. Then, insert the second insert plate 5 into the fixing frame 3 and pass it through... The first insert plate 4 is used to prevent the fixing frame 3 from detaching from the first insert plate 4. Then, the first threaded post 8 is pulled again, causing the first threaded post 8 to drive the rotating block 7 to rotate inside the first mounting plate 6 via the rotating post 10, thereby causing the first threaded post 8 to engage in the corresponding second slot 12. Then, each first nut 9 connected to the first threaded post 8 is rotated in sequence, causing the first nut 9 to move inward to the inner wall, thereby fixing the support frame 1 and the first threaded post 8, connecting the support frame 1 and the platform pedal 2. After moving to the required position via the moving wheels 22, the support plate 17 is placed into the support. Inside the frame 1, the support plate 17 supports the support frame 1. Then, the fixing plate 14 is placed on the front and back of the support frame 1, so that the second threaded post 15 on the inner side wall of the fixing plate 14 passes through the support frame 1. Then, the second nut 16 is rotated to fix the second threaded post 15. Then, the third nut 24 is rotated to disengage the third nut 24 from the third threaded post 23, so that the restriction of the third nut 24 on the third threaded post 23 is removed. Then, the third threaded post 23 is removed. At this time, the first friction box 18 and the second friction box 19 will slide downward, so that the bottom contacts the ground. At this time, the third slot 25 will be aligned with the side wall of the base plate 20. Then, the third nut 24 is inserted into the third slot 25 above the first friction box 18 and the second friction box 19. Then, the third nut 24 is rotated again to restrict the third threaded post 23 again. At this time, the contact area between the adjustable scaffold and the ground is increased through the first friction box 18 and the second friction box 19, which strengthens the stability of the adjustable scaffold. Then, when the first friction box 18 and the second friction box 19 descend, they will be passed through by the locking post 26 on the base plate 20, which further strengthens the overall stability.

Matters not covered in this utility model are common knowledge to those skilled in the art.
