Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, and more specifically, to an adjustable scaffolding support. Background Technology

[0002] Adjustable scaffolding supports, also known as adjustable bases or adjustable bottom supports, are an important component of scaffolding. They are mainly used to adjust the height of scaffolding uprights, ensure stable support at the bottom of the uprights, and effectively transfer the upper load to the foundation ground.

[0003] During current construction, after installing the adjustable support, insert the starting rod of the upright into the screw of the adjustable support. The bottom of the starting rod contacts the upper end of the nut seat. Then, the height of the starting rod and the upright can be adjusted by rotating the nut seat.

[0004] However, each of the current adjustable supports only supports the starting rod through the nut seat, which is not stable enough. After long-term use, the nut seat is prone to plastic deformation or loosening, which directly reduces the support strength and may cause the height of the starting rod to settle, thus leading to local instability of the frame.

[0005] Therefore, it is necessary to provide an adjustable scaffolding support to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide an adjustable scaffolding support to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable scaffolding support, connected to the starting pole of the scaffolding, includes: A base is provided with a screw rod, and a nut seat for supporting the starting rod is threadedly connected to the screw rod. A rotating block is provided on the outer wall of the nut seat. A limiting annular groove is formed at the upper end of the nut seat and is adapted to the outer diameter of the starting rod; A reinforcing seat is threaded onto the screw and located below the nut seat; A supporting component, located on the reinforcing seat, is used to support the rotating block.

[0008] Furthermore, the supporting component includes: A crossbar is rotatably mounted on the reinforcing seat, and a vertical bar is installed on the crossbar, with a support block at the upper end of the vertical bar.

[0009] Furthermore, the bottom of the rotating block is provided with an inner groove that is adapted to the supporting block.

[0010] Furthermore, the outer wall of the reinforcing seat is provided with an annular groove, and the inner wall of the annular groove is slidably connected to an arc-shaped slider connected to the crossbar.

[0011] Furthermore, the inner wall of the annular groove is provided with a groove, and a limiting block connected to the arc-shaped slider is slidably disposed on the inner wall of the groove.

[0012] Furthermore, the crossbar is provided with a socket that is compatible with the vertical bar, and the outer wall of the crossbar is provided with a screw hole that communicates with the socket; The lower side of the vertical rod has a through hole that matches the screw hole.

[0013] Furthermore, it also includes a bracket detachably mounted on the rotating block, with a limit block at the end of the bracket, and a notch adapted to the limit block is provided on the outer wall of the starting rod.

[0014] Furthermore, the upper end of the rotating block is provided with a fixing hole, and the bracket is provided with an oval hole that matches the fixing hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This solution involves adjusting the nut seat to the required height, then slipping the starting rod onto the screw. The bottom of the starting rod is inserted into the limiting ring groove of the nut seat. The nut seat supports the starting rod, and the limiting ring groove restricts the horizontal position of the starting rod, preventing the starting rod and the upright from shifting under stress. This improves the overall stability of the scaffold and greatly enhances the support effect of the nut seat.

[0016] Then, rotate the reinforcing seat to make it rise along the screw. The reinforcing seat will drive the supporting component to rise together, eventually making the supporting component contact the bottom of the rotating block. This allows the supporting component to further support the nut seat, thereby dispersing the pressure transmitted from the starting rod and scaffold to the nut seat, reducing the direct impact pressure on the nut seat, and thus greatly improving the support stability of the nut seat. This can effectively reduce the phenomenon of plastic deformation or loosening of the nut seat after a long period of time, and reduce the occurrence of local scaffold instability caused by high settlement. It has high practicality, is simple and convenient to operate, and is quick to assemble and disassemble, and can be widely promoted. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Please see Figure 1-7 An adjustable scaffolding support, connected to the starting pole 1 of the scaffolding, includes: The base 2 has a screw 3 on it, and a nut seat 4 for supporting the starting rod 1 is threadedly connected to the screw 3. A rotating block 5 is provided on the outer wall of the nut seat 4. The limiting ring groove 6 is opened at the upper end of the nut seat 4 and is adapted to the outer diameter of the starting rod 1; The reinforcing seat 7 is threaded onto the screw 3 and located below the nut seat 4; The supporting component 8 is located on the reinforcing seat 7 and is used to support the rotating block 5.

[0021] In use, first fix each base 2 in its corresponding position, then rotate the nut seat 4 to rotate up or down along the screw 3, adjusting the nut seat 4 to the required height so that multiple nut seats 4 are on the same horizontal plane. Then, slip the starting rod 1 onto the screw 3, with the bottom of the starting rod 1 inserted into the limiting ring groove 6 of the nut seat 4. The nut seat 4 supports the starting rod 1, and the limiting ring groove 6 restricts the horizontal position of the starting rod 1, preventing the starting rod 1 and the upright from shifting under force, thereby improving the overall stability of the scaffold and greatly enhancing the support effect of the nut seat 4.

[0022] Then, the reinforcing seat 7 is rotated, and it rises along the screw 3. At the same time, the reinforcing seat 7 drives the supporting component 8 to rise as well, so that the supporting component 8 contacts the bottom of the rotating block 5. This allows the supporting component 8 to further support the nut seat 4, thereby dispersing the pressure transmitted from the starting rod 1 and the scaffold to the nut seat 4, reducing the direct impact pressure on the nut seat 4, and thus greatly improving the support stability of the nut seat 4. This can effectively reduce the phenomenon of plastic deformation or loosening of the nut seat 4 after a long period of time, and reduce the occurrence of local scaffold instability caused by high settlement. It has high practicality, is simple and convenient to operate, and is quick to assemble and disassemble, and can be widely promoted.

[0023] In this embodiment, preferably, please refer to [reference needed]. Figure 1-4 and Figure 6-7 The supporting component 8 includes: A horizontal bar 81 is rotatably mounted on a reinforcing seat 7. A vertical bar 82 is mounted on the horizontal bar 81, and a support block 83 is provided at the upper end of the vertical bar 82.

[0024] Specifically, when the reinforcing seat 7 is rotated, the horizontal bar 81, the vertical bar 82, and the supporting block 83 will rise or fall together. Simultaneously, the horizontal bar 81 can rotate circumferentially along the reinforcing seat 7, thus positioning the vertical bar 82 and the supporting block 83 below the rotating block 5. When the reinforcing seat 7 rotates and causes the supporting block 83 to rise and contact the rotating block 5, the supporting block 83 can support the rotating block 5 and the nut seat 4. The pressure on the nut seat 4 can be distributed through the supporting block 83, the vertical bar 82, the horizontal bar 81, and the reinforcing seat 7, improving the support stability of the nut seat 4.

[0025] In this embodiment, preferably, please refer to [reference needed]. Figure 6 The bottom of the rotating block 5 is provided with an inner groove 13 that is adapted to the supporting block 83.

[0026] This design allows the support block 83 of the support component 8 to enter the recessed groove 13 of the rotating block 5. The recessed groove 13 can limit the position of the support block 83, thereby preventing the support block 83 from shifting horizontally and further improving the support effect of the support block 83 on the rotating block 5.

[0027] In this embodiment, preferably, please refer to [reference needed]. Figure 2 and Figure 6-7 The outer wall of the reinforcing seat 7 is provided with an annular groove 9, and the inner wall of the annular groove 9 is slidably connected with an arc-shaped slider 10 connected to the crossbar 81.

[0028] With this design, when the crossbar 81 rotates along the reinforcing seat 7, the crossbar 81 will drive the arc-shaped slider 10 to rotate along the annular groove 9, ensuring the smooth rotation of the crossbar 81.

[0029] In this embodiment, preferably, please refer to [reference needed]. Figure 2 and Figure 6-7 The inner wall of the annular groove 9 is provided with a groove 11, and a limiting block 12 connected to the arc-shaped slider 10 is slidably disposed on the inner wall of the groove 11.

[0030] With this design, when the arc-shaped slider 10 rotates along the annular groove 9, the arc-shaped slider 10 will drive the limiting block 12 to rotate along the groove 11, thereby limiting the arc-shaped slider 10 in the horizontal direction, ensuring that the arc-shaped slider 10 can rotate stably in the annular groove 9, and improving the stability of the arc-shaped slider 10.

[0031] In this embodiment, preferably, please refer to [reference needed]. Figure 7 The horizontal bar 81 is provided with a socket 14 that is compatible with the vertical bar 82, and the outer wall of the horizontal bar 81 is provided with a screw hole 15 that communicates with the socket 14. The lower side of the vertical rod 82 has a through hole 16 that matches the screw hole 15.

[0032] Specifically, when installing the vertical rod 82, it can be inserted into the socket 14 of the horizontal rod 81, and then bolts or screws can be turned into the screw holes 15, with the bolts or screws passing through the through holes 16 of the vertical rod 82, thus fixing the vertical rod 82 to the horizontal rod 81. Disassembly is similar; simply remove the bolts or screws to detach the vertical rod 82 from the horizontal rod 81. This design not only facilitates the overall transportation and storage of the reinforcing base 7, reducing space usage, but also allows for easier installation due to its modular design. Furthermore, it enables quick replacement of the vertical rod 82 and the support block 83. If the entire reinforcing base 7 needs to be replaced, the vertical rod 82 and the support block 83 can be replaced as needed.

[0033] In this embodiment, preferably, please refer to [reference needed]. Figure 1 and Figure 3-5 It also includes a bracket 17 that is detachably mounted on the rotating block 5. The end of the bracket 17 is provided with a limit block 18, and the outer wall of the starting rod 1 is provided with a notch 19 that matches the limit block 18.

[0034] With this design, after the starting rod 1 is inserted into the screw 3 and pressed against the nut seat 4, the bracket 17 is installed on the rotating block 5, and the limiting block 18 on the bracket 17 is located in the notch 19 of the starting rod 1. Thus, with the cooperation of the notch 19 and the limiting block 18, the starting rod 1 can be prevented from undergoing vertical displacement, thereby improving the overall stability of the scaffold and making it safer.

[0035] In this embodiment, preferably, please refer to [reference needed]. Figure 3-5 The upper end of the rotating block 5 is provided with a fixing hole 20, and the bracket 17 is provided with an oval hole 21 that matches the fixing hole 20.

[0036] With this design, when installing bracket 17, the oblong hole 21 of bracket 17 is aligned with the fixing hole 20 of rotating block 5. After the limiting block 18 of bracket 17 is in the designated position, bolts are passed through the oblong hole 21 and the fixing hole 20 to fix bracket 17 onto rotating block 5, making assembly and disassembly convenient. Furthermore, the design of the oblong hole 21 allows for adjustment of the positions of bracket 17 and limiting block 18 as needed.
