Description
Technical Field
[0001] This utility model relates to the field of building component technology, and in particular to a fixing device for cantilevered scaffold uprights. Background Technology
[0002] With the acceleration of urbanization and the booming development of the construction industry, there is an increasing number of high-rise buildings, large public facilities, and buildings with complex structures. These buildings often require high-altitude operations during construction, and cantilevered scaffolding, as an effective temporary support structure, can meet this demand. It not only provides a safe working platform but also effectively supports and protects construction personnel, materials, and equipment, ensuring the smooth progress of the construction process.
[0003] Traditional cantilever scaffolding typically employs a structure where scaffolding uprights are fixed to cantilevered I-beams. In the prior art, utility model application number 202220652232.5 provides a cantilever scaffolding upright positioning and fixing device, including a movable body, a positioning rod, and a clamping component. The movable body has a U-shaped cross-section and slides onto the cantilevered I-beam. This device not only allows for adjustment of the upright's position on the cantilever beam but also applies to a wider range of cantilever beam models. However, in actual construction applications, it has been found that due to the scaffolding's own weight, the movable body often presses tightly against the top of the I-beam, resulting in significant friction between the contact surfaces. It is difficult for construction workers to directly move the movable body across the cantilever beam to adjust the upright's position. Therefore, this application provides a cantilever scaffolding upright fixing device to meet this requirement. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a fixing device for the uprights of cantilever scaffolding to solve the problem of inconvenient position adjustment of the uprights on the I-beam cantilever beam.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A cantilever scaffold upright fixing device includes a sleeve block, which is movably fitted onto the cantilever I-beam and can move up and down. A rubber pad block is provided on the inner top wall of the sleeve block. A plug rod is vertically fixed on the top surface of the sleeve block and is plugged into the upright. A U-shaped frame is also fixed on the top surface of the sleeve block. A first lead screw is vertically threaded through the top wall of the U-shaped frame. A roller is assembled at the bottom end of the first lead screw. The top wall of the sleeve block and the rubber pad block are provided with slots that allow the roller to pass through vertically.
[0007] Optionally, a wheel frame is rotatably connected to the bottom end of the first lead screw, and the roller is mounted on the wheel frame.
[0008] Optionally, a horizontal arm is fixed to the top of the wheel frame, and a vertical groove is provided on the inner side wall of the U-shaped frame, with the end of the arm slidingly engaged with the groove.
[0009] Optionally, the U-shaped frame and rollers are provided in a pair, with the pair of U-shaped frames and rollers distributed at both ends of the top surface of the sleeve block.
[0010] Optionally, a second lead screw is threaded vertically through the bottom end of the sleeve block, and two second lead screws are provided.
[0011] Optionally, one end of the second lead screw that extends into the sleeve is rotatably connected to a stop plate, and a rubber pad is provided on the upper surface of the stop plate.
[0012] Optionally, the plug rod is located at the center of the top surface of the sleeve block, and the top surface of the plug rod is spherical.
[0013] Optionally, the bottom end of the plug rod is provided with a base, and the base is fixedly connected to the top end of the sleeve block.
[0014] Optionally, the upper surface of the base has a slot around the plug rod that allows the upright to be inserted. A rubber ring is embedded in the slot and engages with the upright.
[0015] Optionally, a rubber strip is vertically provided on the side wall of the plug rod, and multiple rubber strips are provided around the plug rod, with the top of most of the rubber strips having an inclined surface that smoothly connects to the side wall of the plug rod.
[0016] Compared with the prior art, this utility model has at least the following beneficial effects:
[0017] In the above scheme, by setting up a sleeve block and a plug-in rod, the sleeve block is fitted onto the cantilevered I-beam, and the bottom end of the upright is fitted onto the plug-in rod and inserted into the slot to nest with the rubber ring. This enables a quick connection between the upright and the cantilevered I-beam. In addition, by setting up rubber pads, the weight of the upright and the scaffold itself applies pressure to the sleeve block, which makes the rubber pads on the top wall inside the sleeve block press against the top of the cantilevered I-beam. Turning the second screw pushes the abutment plate upward, making the rubber pads on the abutment plate press against the bottom of the cantilevered I-beam. The rubber pads on the top wall inside the sleeve block press against the top of the cantilevered I-beam again. The rubber pads and the abutment plate can significantly increase the frictional resistance between the sleeve block and the cantilevered I-beam, thereby restricting the movement of the sleeve block on the cantilevered I-beam and achieving a quick connection and restricted positioning between the upright and the cantilevered I-beam.
[0018] By setting up a U-shaped frame and rollers, turning the second screw drives the abutment plate downwards, and turning the first screw pushes the rollers downwards, so that the rollers pass through the slot and abut against the upper surface of the cantilevered I-beam, and push the sleeve block upwards. The rubber pad block on the inner top wall of the sleeve block disengages from the upper surface of the upright, which can release the movement restriction of the sleeve block on the cantilevered I-beam. With the rolling of the rollers, the sleeve block can be easily pushed to move along the length of the cantilevered I-beam, and the position of the bottom end of the upright on the cantilevered I-beam can be adjusted.
[0019] The overall structure of this application is reasonable, which can quickly connect the uprights and the cantilevered I-beams, and facilitates the adjustment of the position of the uprights on the cantilevered I-beams. It is highly flexible, easy to operate, and more conducive to the assembly of cantilevered scaffolding during the construction process. Attached Figure Description

[0034] like Figures 1 to 3As shown, an embodiment of this utility model provides a cantilever scaffolding upright fixing device for connecting the upright 1 and the cantilever I-beam 2. It includes a sleeve block 3, which is movably fitted onto the cantilever I-beam 2 and can move up and down. A rubber pad block 9 is provided on the inner top wall of the sleeve block 3. A plug-in rod 4 is vertically fixed on the top surface of the sleeve block 3, and the plug-in rod 4 is plugged into the upright 1. A U-shaped frame 5 is also fixed on the top surface of the sleeve block 3. A first threaded rod 7 is vertically threaded through the top wall of the U-shaped frame 5, and a roller 6 is fitted at the bottom end of the first threaded rod 7. Slots 8 are provided on the top wall of the sleeve block 3 and the rubber pad block 9 to allow the roller 6 to pass vertically through. Through this structure, the sleeve block 3 is fitted onto the cantilever I-beam 2, and the bottom end of the upright 1 is fitted onto the plug-in rod 4. The upright 1 and the... The weight of the scaffold itself applies pressure to the sleeve block 3, causing the rubber pad block 9 on the inner top wall of the sleeve block 3 to press against the top of the cantilevered I-beam 2, increasing the frictional resistance between the sleeve block 3 and the cantilevered I-beam 2, and restricting the movement of the sleeve block 3 on the cantilevered I-beam 2. This enables a quick connection between the upright 1 and the cantilevered I-beam 2. By turning the first screw 7, the roller 6 is pushed downward until it passes through the slot 8 and abuts against the upper surface of the cantilevered I-beam 2, lifting the sleeve block 3 upward. This causes the rubber pad block 9 on the inner top wall of the sleeve block 3 to detach from the upper surface of the upright 1, releasing the movement restriction of the sleeve block 3 on the cantilevered I-beam 2. With the rolling of the roller 6, the sleeve block 3 can be easily pushed to move along the length of the cantilevered I-beam 2, adjusting the position of the bottom end of the upright 1 on the cantilevered I-beam 2.
[0035] like Figures 1 to 3 As shown, the bottom end of the first lead screw 7 is rotatably connected to a wheel frame 11, the roller 6 is mounted on the wheel frame 11, the top of the wheel frame 11 is horizontally fixed with a bar arm 12, and the inner side wall of the U-shaped frame 5 is vertically provided with a sliding groove 13. The end of the bar arm 12 is slidably engaged with the sliding groove 13. This structure enables the roller 6 to maintain a rolling state along the length direction of the cantilevered I-beam 2.
[0036] like Figures 1 to 4 As shown, a pair of U-shaped frames 5 and rollers 6 are provided. The pair of U-shaped frames 5 and rollers 6 are distributed at both ends of the top surface of the sleeve block 3, which is conducive to the movement of the sleeve block 3 on the cantilevered I-beam 2. The plug rod 4 is set at the center of the top surface of the sleeve block 3. The top surface of the plug rod 4 is set as a spherical surface, which is conducive to the bottom end of the upright 1 being sleeved.
[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, a second lead screw 10 is vertically threaded through the bottom end of the sleeve block 3. Two second lead screws 10 are provided. One end of the second lead screw 10 that extends into the sleeve block 3 is rotatably connected to a stop plate 18. A rubber pad 19 is provided on the upper surface of the stop plate 18. Twisting the second lead screw 10 pushes the stop plate 18 upward, so that the rubber pad 19 on the stop plate 18 abuts against the bottom of the cantilevered I-beam 2. The rubber pillow block 9 on the inner top wall of the sleeve block 3 abuts against the top of the cantilevered I-beam 2. The rubber pillow block 9 and the stop plate 18 can greatly increase the frictional resistance between the sleeve block 3 and the cantilevered I-beam 2, restricting the movement of the sleeve block 3 on the cantilevered I-beam 2.
[0038] like Figure 1 , Figure 2 and Figure 4 As shown, the bottom end of the plug rod 4 is provided with a base 14, which is fixedly connected to the top end of the sleeve block 3. A slot 15 is formed around the upper surface of the base 14 to accommodate the insertion of the upright rod 1. A rubber ring 16 is embedded in the slot 15 and fits into the upright rod 1. A rubber strip 17 is vertically arranged on the side wall of the plug rod 4. Multiple rubber strips 17 are arranged around the plug rod 4. The top end of most of the rubber strips 17 is provided with an inclined surface that smoothly connects to the side wall of the plug rod 4, which is conducive to the upright rod 1 being fitted onto the plug rod 4. The bottom end of the upright rod 1 is fitted onto the plug rod 4 and inserted into the slot 15 and nested with the rubber ring 16. The rubber strip 17 is deformed by the compression of the upright rod 1, which can make the upright rod 1 and the plug rod 4 fit tightly together. The base 14 increases the force-bearing area between the bottom end of the upright rod 1 and the sleeve block 3. The slot 15 can assist in the positioning of the bottom end of the upright rod 1.
[0039] The working principle of the technical solution provided by this utility model is as follows:
[0040] In use, the sleeve block 3 is fitted onto the cantilevered I-beam 2. The bottom end of the upright 1 is fitted onto the plug rod 4 and inserted into the slot 15, nesting with the rubber ring 16. The weight of the upright 1 and the scaffold itself applies pressure to the sleeve block 3, causing the rubber pad 9 on the inner top wall of the sleeve block 3 to press against the top of the cantilevered I-beam 2. Then, the second screw 10 is turned to push the abutment plate 18 upward, causing the rubber pad 19 on the abutment plate 18 to press against the bottom of the cantilevered I-beam 2. The rubber pad 9 on the inner top wall of the sleeve block 3 presses against the top of the cantilevered I-beam 2 again. The rubber pad 9 and the abutment plate 18 significantly increase the frictional resistance between the sleeve block 3 and the cantilevered I-beam 2, thereby restricting the movement of the sleeve block 3 on the cantilevered I-beam 2. This achieves a quick connection between the upright 1 and the cantilevered I-beam 2. In one step, the second lead screw 10 is turned to drive the abutment plate 18 downward, and then the first lead screw 7 is turned to push the roller 6 downward until the roller 6 passes through the slot 8 and abuts against the upper surface of the cantilevered I-beam 2 and pushes the sleeve block 3 upward, so that the rubber pillow block 9 on the inner top wall of the sleeve block 3 is separated from the upper surface of the upright 1, thereby releasing the movement restriction of the sleeve block 3 on the cantilevered I-beam 2. With the rolling of the roller 6, the sleeve block 3 can be easily pushed to move along the length direction of the cantilevered I-beam 2, and the position of the bottom end of the upright 1 on the cantilevered I-beam 2 can be adjusted. The overall structure is reasonable, which can quickly realize the connection between the upright 1 and the cantilevered I-beam 2, and facilitate the adjustment of the position of the upright 1 on the cantilevered I-beam 2. It is highly flexible, easy to operate, and more conducive to the assembly operation of cantilevered scaffolding in the construction process.

To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
