Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, specifically to prefabricated modular cup-lock steel pipe scaffolding. Background Technology

[0002] Cup-lock steel pipe scaffolding is a new type of construction scaffolding. It features a modular design, allowing for rapid assembly and disassembly, significantly improving construction efficiency. Furthermore, the cup-lock connection between modules makes scaffolding erection simpler and faster.

[0003] Utility model patent CN210421893U discloses a cup-lock scaffold for bridge and culvert applications. This cup-lock scaffold includes uprights and horizontal bars. A horizontal bar connector is fixedly connected to the end face of each horizontal bar, and an adjustable cup-lock is movably connected to each upright. The adjustable cup-lock includes an upper cup-lock, a lower cup-lock, and positioning holes. The upper cup-lock is sleeved on the wall of the upright, and four positioning pins are fixedly connected to its lower surface. The positioning holes are located on the wall of the horizontal bar. An upper adjusting and fixing mechanism is fixedly connected to the upper surface of the upper cup-lock, and a lower adjusting and positioning mechanism is slidably connected to the inner wall of the lower cup-lock. The lower cup-lock is sleeved on the wall of the upright via the lower adjusting and positioning mechanism. By configuring adjustable cup buckles, an upper cup buckle, a positioning pin, an upper adjusting and fixing mechanism, a lower cup buckle, a lower adjusting and positioning mechanism, an upper fixing collar, a first sliding groove, an upper arc pressure plate, an upper bolt, a lower fixing collar, a second sliding groove, a lower arc pressure plate, a lower bolt, a rough plate, and positioning holes, when installation is required, the crossbar connector on the crossbar is placed into the lower cup buckle, and then the upper cup buckle is pressed down to lock the crossbar connector between the upper and lower cup buckles. The positioning pin at the bottom of the upper cup buckle is inserted into the positioning hole on the crossbar for positioning, preventing the crossbar from rotating or sliding. When adjusting the fixed height of the crossbar, which requires changing the position of the upper and lower cup buckles, the lower bolt is loosened, and the lower fixing collar and lower cup buckle are adjusted up and down along the upright. For positions requiring fixation, tightening the four lower bolts compresses the lower arc-shaped pressure plates, causing these plates to press against the upright through the rough edges, thus securing it. The lower cup buckle is then fitted onto the surfaces of these four arc-shaped pressure plates. As the lower cup buckle slides downwards under gravity, it presses against the four inner arc-shaped pressure plates, transforming the downward force of gravity into pressure on the upright, increasing friction and thus ensuring a more stable fixation. Similarly, loosening and tightening the upper bolts allows for the vertical movement and fixation of the upper cup buckle. This allows for convenient adjustment of the height of the upper and lower cup buckles to adjust the usable height of the crossbar, resulting in a more secure connection that prevents loosening and offers strong practicality.

[0004] Although the cup-lock scaffolding used for bridge and culvert construction is convenient for adjusting the height of the horizontal bars, the device still has the following problems in actual use: In this device, the cup-lock is fixed to the upright through the friction between the arc-shaped pressure plate and the upright, but the stability of this connection method is poor, and slippage may occur in actual use, thereby increasing the safety hazards of the scaffolding. In view of this, we propose a prefabricated modular cup-lock steel pipe scaffolding. Utility Model Content

[0005] To solve the above problems, this utility model provides a prefabricated modular cup-lock steel pipe scaffold.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] The prefabricated modular cup-lock steel pipe scaffolding includes uprights, with multiple positioning slots on the upper and lower sides of the outer wall of the uprights;

[0008] Each upright has a cup-buckle assembly installed at the positioning groove on its exterior. The cup-buckle assembly includes two symmetrical cups. A connecting sleeve is coaxially fixed to the two opposite ends of the two cups. The upright passes through the cups and the connecting sleeve and is slidably connected to the connecting sleeve. Two symmetrical shells are fixed to the outer wall of the connecting sleeve. The shells are open. A slider is slidably installed at the opening of each shell. Multiple positioning blocks are fixed to the two opposite ends of the two sliders. The positioning blocks pass through the connecting sleeve and are inserted into the corresponding positioning groove. A pull rod is fixed to the two opposite ends of the two sliders. The end of the pull rod passes through the shell and is slidably connected to the shell. A spring is sleeved on the outside of the pull rod to press against the slider.

[0009] A crossbar is installed between two adjacent bowl buckle components. A protrusion is fixed at both ends of the crossbar. Slots are opened at both ends of the protrusion. The bowl buckle edges of the bowls on the upper and lower sides are inserted into the slots. Limiting blocks are fixed on the outer wall of the protrusion. The upper and lower ends of the limiting blocks are inserted into the bowl openings of the bowls on the upper and lower sides, respectively.

[0010] Furthermore, the limiting block and the protrusion are integrally formed structures, and the two ends of the crossbar are tightly welded to the protrusion.

[0011] Furthermore, the slider has an overall rectangular shape, and its size is adapted to the opening size of the housing.

[0012] Furthermore, the positioning block and the slider are integrally formed structures, and both the positioning block and the slider are made of galvanized steel.

[0013] Furthermore, a dial is fixedly connected to the end of the pull rod by bolts, and the dial is made of rubber.

[0014] Furthermore, the outer wall of the upright has two symmetrical limiting grooves, and the inner wall of the connecting sleeve has two limiting strips that are slidably connected to the limiting grooves.

[0015] Furthermore, the cup and the connecting sleeve are integrally formed, and the cross-sectional shape of the cup is bowl-shaped.

[0016] Furthermore, a base is tightly welded to the bottom end of the upright, and the base has an overall shape that is narrower at the top and wider at the bottom.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] By using the cup-lock assembly and crossbar: adjusting the height of the cup-lock assembly, pulling the lever causes the positioning block to disengage from the positioning slot and then engage with the positioning slot of the appropriate height, the cup-lock can be adjusted to the appropriate height. The engagement between the positioning block and the positioning slot has the advantages of reliable connection and not easy to disengage, thus ensuring the reliable installation of the cup-lock assembly and ensuring the safety of scaffolding use.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This embodiment provides a technical solution:

[0030] Please see Figures 1-5 As shown, the prefabricated modular cup-lock steel pipe scaffolding includes an upright 1. Multiple positioning slots 10 are formed on the upper and lower sides of the outer wall of the upright 1. Cup-lock assemblies 2 are installed on the outside of the upright 1 at each positioning slot 10. Each cup-lock assembly 2 includes two symmetrical cups 20. A connecting sleeve 21 is coaxially fixed to the two opposite ends of each cup 20. The upright 1 passes through the cups 20 and the connecting sleeve 21 and is slidably connected to the connecting sleeve 21. Two symmetrical shells 22 are fixed to the outer wall of the connecting sleeve 21. Each shell 22 is open, and a slider 23 is slidably installed at the opening of each shell 22. Multiple positioning blocks 24 are fixed to the two opposite ends of each slider 23. 24 passes through the connecting sleeve 21 and is inserted into the corresponding positioning groove 10; two opposite ends of the two sliders 23 are fixed with pull rods 25, the ends of the pull rods 25 pass through the housing 22 and are slidably connected to the housing 22, and springs 26 for pressing against the sliders 23 are sleeved on the outside of the pull rods 25; a crossbar 3 is installed between two adjacent bowl buckle assemblies 2, and protrusions 30 are fixed at both ends of the crossbar 3. Slots 300 are opened at both the upper and lower ends of the protrusions 30, and the bowl buckle edges of the bowls 20 on the upper and lower sides are inserted into the slots 300. Limiting blocks 31 are fixed on the outer wall of the protrusions 30, and the upper and lower ends of the limiting blocks 31 are respectively inserted into the bowl openings of the bowls 20 on the upper and lower sides.

[0031] In this embodiment, the limiting block 31 and the protrusion 30 are integrally formed structures, and both ends of the crossbar 3 are tightly welded to the protrusion 30. This design improves the overall integrity and stability of the structure, making the connection between the crossbar 3 and the protrusion 30 more robust and reliable. Simultaneously, welding ensures a secure connection between the crossbar 3 and the protrusion 30, enhancing the overall strength and stability of the structure.

[0032] In this embodiment, the slider 23 has a rectangular shape, and its size is adapted to the opening size of the housing 22. This design facilitates the smooth sliding of the slider 23 within the housing 22, improving the fit between components and ease of operation.

[0033] In this embodiment, the positioning block 24 and the slider 23 are integrally formed structures, both made of galvanized steel. This integral forming structure improves the connection strength between the positioning block 24 and the slider 23, thereby enhancing the stability and safety of the structure. Simultaneously, the galvanized steel material possesses excellent corrosion resistance and high strength, extending the service life of the components while maintaining the overall structural stability.

[0034] In this embodiment, a dial 27 is bolted to the end of the lever 25. The dial 27 is made of rubber. The rubber dial 27 provides a good feel and anti-slip performance, making it easy for the user to operate.

[0035] In this embodiment, two symmetrical limiting grooves 11 are formed on the outer wall of the upright 1, and two limiting strips 210 that are slidably connected to the limiting grooves 11 are fixed on the inner wall of the connecting sleeve 21. The sliding connection design of the limiting grooves 11 and the limiting strips 210 ensures the stable sliding and positioning of the connecting sleeve 21 on the upright 1, thereby improving the stability and safety of the overall structure.

[0036] In this embodiment, the cup 20 and the connecting sleeve 21 are integrally formed, and the cross-sectional shape of the cup 20 is bowl-shaped. The integrally formed structure improves the connection strength between the cup 20 and the connecting sleeve 21, while the bowl-shaped design facilitates the connection of the limiting block 31.

[0037] In this embodiment, a base 12 is tightly welded to the bottom end of the upright 1. The base 12 has an overall shape that is narrower at the top and wider at the bottom. The design of the base 12, which is narrower at the top and wider at the bottom, improves the stability of the upright 1; the tight welding ensures a firm connection between the base 12 and the upright 1.

[0038] It should be added that the housing 22, pull rod 25, slider 23, spring 26 and positioning block 24 in this embodiment are all made of stainless steel. Stainless steel has high strength and good durability, and can withstand large mechanical stress and pressure to ensure long-term stable operation of the equipment. At the same time, it also has good corrosion resistance. The use of this material ensures the structural strength and service life of the housing 22, pull rod 25, slider 23, spring 26 and positioning block 24.

[0039] In practical use, the user first pulls out the lever 27, which drives the lever 25 to move horizontally. The lever 25 then drives the slider 23 to move, which in turn compresses the spring 26. Simultaneously, the slider 23 causes multiple positioning blocks 24 to disengage from the positioning groove 10. At this point, the user pushes the cup 20 up or down to the appropriate height. When the cup 20 reaches the appropriate height, the user releases the spring 26. Under the elastic action of the spring 26, the positioning block 24 is inserted into the positioning groove 10, the connecting sleeve 21 is fixed to the upright 1, and the cup 20 is fixed. The user can repeat the above steps to adjust the height of the multiple cups 20 in turn.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
