Abstract
Description
Technical Field
[0001] This utility model relates to the field of scaffolding technology, and in particular to a steel pipe scaffolding upright support device. Background Technology
[0002] The steel pipe scaffolding upright support device is a transition structure connecting the scaffolding uprights to the foundation (or floor, ground). Its core function is to safely transfer the vertical load (including the scaffolding's own weight, construction load, wind load, etc.) borne by the uprights to the foundation, while restraining the horizontal displacement and vertical loosening at the bottom of the uprights, ensuring the vertical stability of the uprights. It is a key component to ensure the overall load-bearing capacity and safety of the scaffolding.
[0003] The existing method of fixing the pole simply involves placing or inserting the bottom of the pole onto the surface of the pad, without any additional constraints, as shown in the instruction manual. Figure 1 As shown, under the action of horizontal forces (such as construction vibrations and wind loads), the uprights are prone to lateral sliding or tilting, compromising their verticality. Since the stability of scaffolding depends on the vertical force on the uprights, misalignment can cause the uprights to bear additional bending moments, and may even lead to overall instability. Utility Model Content
[0004] This utility model provides a steel pipe scaffolding upright support device, which solves the problem mentioned in the background art that the upright is easily laterally slipped or tilted when the bottom of the upright is simply placed or inserted into the surface of the pad without additional constraints.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel pipe scaffolding upright support device, comprising a base plate, an inner support rod, a threaded rotating cylinder, a threaded connecting cylinder, and a fixing screw. The base plate has multiple insertion holes evenly distributed linearly for inserting the upright. The inner support rod is fixed inside the insertion holes. The upright is sleeved and inserted into the outer side of the inner support rod. One end of the upright is threadedly connected to a threaded sleeve. Two threaded rotating cylinders are rotatably connected to the outer circumferential side of the threaded sleeve. Two threaded connecting cylinders are provided on the outer circumferential side of the insertion holes. The threaded connecting cylinders are fixed to the base plate. The fixing screw passes through the interior of the threaded rotating cylinder and the threaded connecting cylinder and is threadedly connected to both.
[0006] Preferably, the inner support rod is perpendicular to the pad and coaxially arranged with the insertion hole.
[0007] Preferably, the outer diameter of the upright is the same as the inner diameter of the insertion hole.
[0008] Preferably, the two threaded cylinders on the threaded sleeve are arranged symmetrically.
[0009] Preferably, a side sleeve is fixedly connected to the outer peripheral side of the threaded sleeve, and the axis of the side sleeve is perpendicular to the axis of the threaded sleeve.
[0010] Preferably, an annular groove is formed on the inner circumferential side of the side cylinder, and the axis of the annular groove coincides with the axis of the side cylinder.
[0011] Preferably, a connecting post is fixedly connected to one end of the threaded rotary cylinder, and a rotating ring is fixedly connected to the outer peripheral side of the connecting post. The rotating ring is slidably connected in the annular groove, and the threaded rotary cylinder is rotatably connected to the threaded sleeve through the rotating ring.
[0012] Preferably, the threaded connecting cylinder corresponds to the threaded rotating cylinder, and the threaded connecting cylinder is inclined upward.
[0013] Preferably, the two threaded mating cylinders arranged symmetrically are inclined in opposite directions.
[0014] Compared with the prior art, the beneficial effects of this utility model are: Insert the upright into the hole on the pad. At this point, the upright is fitted onto the outside of the inner support rod, which supports the upright from the inside. The hole wall initially restricts the lateral movement of the upright from the outside, ensuring its initial verticality. Tighten the threaded sleeve to the bottom of the upright, fixing its position with the threaded connection to form a single unit with the upright. Next, rotate the threaded drum to align it with the corresponding threaded mating cylinder on the pad. Then, insert the fixing screw into the aligned threaded drum and threaded mating cylinder, tightening the fixing screw to secure the threaded drum and threaded mating cylinder together with the threaded connection, forming a double-sided lateral constraint from the upright to the pad. This device effectively prevents radial deformation of the upright by supporting it from the inside with the inner support rod. The double-sided inclined constraint structure composed of the threaded sleeve, threaded drum, threaded mating cylinder, and fixing screw restricts lateral sliding of the upright from the outside, significantly improving the overall load-bearing capacity and safety of the scaffolding.

[0017] 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 scope of protection of the present utility model.
[0018] This utility model provides a steel pipe scaffolding upright support device, such as... Figure 2 and Figure 3 As shown, the structure includes a pad 1, an inner support rod 2, a threaded rotating cylinder 5, a threaded connecting cylinder 6, and a fixing screw 7. The pad 1 serves as a transitional load-bearing structure between the upright 3 and the foundation (ground or floor), evenly distributing the load transmitted by the upright 3 to the foundation. Multiple insertion holes 11 for inserting the upright 3 are linearly and evenly distributed on the pad 1. The inner support rod 2 is fixed inside the insertion holes 11, and the upright 3 is inserted into the outer side of the inner support rod 2. This coaxial arrangement with the insertion holes 11 and perpendicular to the pad 1 helps ensure the initial verticality of the upright 3 after insertion, supports the upright 3 from the inside, enhances the structural strength of the bottom of the upright 3, and prevents the upright 3 from bending due to excessive force. One end of the upright 3 is threadedly connected to a threaded sleeve 4. Two threaded rotating cylinders 5 are rotatably connected to the outer circumference of the threaded sleeve 4. Two threaded connecting cylinders 6 are provided on the outer circumference of the insertion holes 11. The threaded connecting cylinders 6 are fixed to the pad 1, and the fixing screw 7 passes through the threaded rotating cylinders 5 and the threaded connecting cylinders 6 and is threadedly connected to both.
[0019] The bottom outer circumference of the upright 3 is provided with external threads.
[0020] like Figure 3 As shown, the inner support rod 2 is perpendicular to the pad 1 and coaxially arranged with the insertion hole 11. The outer diameter of the upright rod 3 is the same as the inner diameter of the insertion hole 11.
[0021] like Figure 2 and Figure 4 As shown, two threaded cylinders 5 are symmetrically arranged on the threaded sleeve 4. A side cylinder 41 is fixedly connected to the outer circumferential side of the threaded sleeve 4, and the axis of the side cylinder 41 is perpendicular to the axis of the threaded sleeve 4. Figure 5An annular groove 411 is provided on the inner circumferential side of the side cylinder 41 shown, and the axis of the annular groove 411 coincides with the axis of the side cylinder 41. A connecting post 51 is fixedly connected to one end of the threaded rotating cylinder 5, and a rotating ring 52 is fixedly connected to the outer circumferential side of the connecting post 51. The rotating ring 52 is slidably connected in the annular groove 411, and the threaded rotating cylinder 5 is rotatably connected to the threaded sleeve 4 through the rotating ring 52.
[0022] like Figure 2 and Figure 3 As shown, the threaded connecting cylinder 6 corresponds to the threaded rotating cylinder 5, and the threaded connecting cylinder 6 is inclined upwards. The two symmetrically arranged threaded connecting cylinders 6 are inclined in opposite directions.
[0023] Using this utility model, such as Figure 2 and Figure 3 As shown, insert the upright 3 into the insertion hole 11 on the pad 1. At this time, the upright 3 is sleeved on the outside of the inner support rod 2. The inner support rod 2 supports the upright 3 from the inside. The wall of the insertion hole 11 initially restricts the lateral movement of the upright 3 from the outside, ensuring the initial verticality of the upright 3. Tighten the threaded sleeve 4 to the bottom of the upright 3, and fix the position of the threaded sleeve 4 through the threaded connection, so that it forms an integral part with the upright 3. Next, rotate the threaded drum 5 (by using the sliding of the rotating ring 52 in the annular groove 411 of the side cylinder 41 to achieve rotation), so that the threaded drum 5 is aligned with the corresponding threaded mating cylinder 6 on the pad 1. Then, insert the fixing screw 7 into the aligned threaded drum 5 and threaded mating cylinder 6, and tighten the fixing screw 7. The threaded drum 5 and threaded mating cylinder 6 are fastened through the threaded connection, forming a double-sided lateral constraint from the upright 3 to the pad 1. The device supports the upright 3 from the inside through the inner support rod 2, effectively preventing radial deformation of the upright 3. The double-sided inclined constraint structure composed of the threaded sleeve 4, the threaded rotating cylinder 5, the threaded connecting cylinder 6 and the fixing screw 7 restricts the lateral sliding of the upright 3 from the outside, significantly improving the overall load-bearing capacity and safety of the scaffold.
