Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a reusable positioning device for the uprights of a cantilevered I-beam scaffold. Background Technology

[0002] During construction, when using cantilevered scaffolding, I-beams are typically used as supports. A positioning steel bar is then fixed to the top surface of the cantilevered portion of the I-beam, and the scaffold uprights are inserted into this positioning steel bar. The positioning steel bar can position the uprights and also has an anti-slip function.

[0003] Currently, in many construction sites, the positioning of scaffolding uprights on cantilevered I-beams is done by welding. This welding process is time-consuming, costly, and the I-beams are disposable, wasting a lot of steel. The high temperature during welding also damages the I-beams. Utility Model Content

[0004] The purpose of this utility model is to provide a reusable positioning device for the uprights of cantilevered scaffolding made of I-beams. The device has a simple structure, is quick to install, can be reused, reduces material waste, does not require welding, and will not damage the I-beams.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0006] A reusable positioning device for cantilevered scaffolding uprights includes a concrete floor slab, an I-beam installed on the surface of the concrete floor slab, and a U-shaped reinforcing bar embedded inside the concrete floor slab. The I-beam passes through the U-shaped reinforcing bar and is pressed and fixed by it. The end of the I-beam away from the U-shaped reinforcing bar extends to the outside of the concrete floor slab and is suspended in the air. The device also includes a positioning device that is detachably installed at the suspended end of the I-beam. The side of the positioning device is provided with a locking member that is detachably connected to the U-shaped reinforcing bar. The locking member locks the positioning device to the suspended end of the I-beam.

[0007] In this scheme, the concrete floor slab serves as the foundation of the entire structure. The concrete floor slab provides a stable support surface, ensuring that the I-beams and scaffold uprights can be safely fixed and cantilevered. Due to its excellent mechanical properties and load-bearing capacity, the I-beam is selected as the main support structure for the cantilevered scaffold uprights. It passes through and is pressed and fixed by U-shaped steel bars, making the installation method both stable and convenient for subsequent adjustments or disassembly. The end of the I-beam furthest from the U-shaped reinforcing bar extends to the outside of the concrete floor slab and is suspended in the air, providing sufficient cantilever length for the scaffolding uprights. A positioning device installed at the suspended end of the I-beam is responsible for accurately positioning and firmly fixing the scaffolding uprights to the I-beam, preventing displacement or tipping during construction. A locking element movable on the side of the positioning device connects the positioning device to the U-shaped reinforcing bar. Through the locking element, the positioning device can be firmly locked to the suspended end of the I-beam, ensuring the stability and safety of the scaffolding uprights. The locking element and U-shaped reinforcing bar are detachable, and the positioning device can also be disassembled. This allows for the reuse of both the disassembled positioning device and locking element, reducing material waste and lowering costs. Furthermore, the device has a simple structure, is quick and efficient to install, and requires no welding during installation, thus preventing damage to the I-beam.

[0008] Optionally, the positioning device includes a fixed sleeve and a positioning rod. The fixed sleeve is a rectangular steel cylinder with one end open and the other end closed. The positioning rod is detachably connected to the top surface of the fixed sleeve. The diameter of the positioning rod is adapted to the inner diameter of the upright of the scaffold. Locking elements are provided on both sides of the fixed sleeve.

[0009] Optionally, a fixing plate is welded to the bottom end of the positioning rod. The fixing plate has through holes on both sides of the positioning rod. Multiple threaded posts that are adapted to the through holes are welded to the top surface of the fixing sleeve along the length direction. The threaded posts are located on both sides of the axis of the positioning sleeve. After passing through the through holes, the threaded posts are threaded with a matching locking nut at their upper ends.

[0010] Optionally, the inner cavity of the fixing sleeve is adapted to the size of the I-beam.

[0011] Optionally, the locking element is a steel wire rope, with one end of the steel wire rope being movably connected to the side wall of the fixed sleeve and the other end being detachably connected to the U-shaped steel bar.

[0012] Optionally, one end of the wire rope is connected to a tensioner, and one end of the tensioner has a hook for connecting to a U-shaped reinforcing bar.

[0013] Optionally, a fixing ring for connecting the wire rope is welded to the side wall of the fixing sleeve, and the end of the wire rope away from the tensioner passes through the fixing ring and is fixed by the wire rope buckle.

[0014] Optionally, the retaining ring is formed by bending steel bars.

[0015] Optionally, the tensioner is a stainless steel turnbuckle.

[0016] The beneficial effects of this utility model are:

[0017] 1. In this utility model, the positioning device installed on the suspended end of the I-beam is responsible for accurately positioning and firmly fixing the scaffold uprights to the I-beam, preventing displacement or tilting during construction. The locking component movably installed on the side of the positioning device is used to connect the positioning device and the U-shaped rebar. Through the locking component, the positioning device can be firmly locked to the suspended end of the I-beam, ensuring the stability and safety of the scaffold uprights. The locking component and the U-shaped rebar are detachable, and the positioning device can also be disassembled. Thus, the disassembled positioning device and locking component can be reused, reducing material waste and lowering costs. At the same time, the device has a simple structure, is quick and efficient to install, and does not require welding during installation, thus not damaging the I-beam. Attached Figure Description

[0025] Example

[0026] A reusable positioning device for cantilevered scaffolding uprights made of I-beam 1 includes a concrete floor slab 12, an I-beam 1 installed on the surface of the concrete floor slab 12, and a U-shaped steel bar 2 embedded inside the concrete floor slab 12. The I-beam 1 passes through the U-shaped steel bar 2 and is pressed and fixed by it. One end of the I-beam 1 away from the U-shaped steel bar 2 extends to the outside of the concrete floor slab 12 and is suspended. The device also includes a positioning device that is detachably installed at the suspended end of the I-beam 1. The side of the positioning device is provided with a locking member that is detachably connected to the U-shaped steel bar 2. The locking member locks the positioning device to the suspended end of the I-beam 1.

[0027] In this embodiment, as Figure 1 As shown, the concrete floor slab 12 serves as the foundation of the entire structure, providing a stable support surface and ensuring that the I-beam 1 and the scaffold uprights can be safely fixed and cantilevered. Due to its excellent mechanical properties and load-bearing capacity, the I-beam 1 is selected as the main support structure for the cantilevered scaffold uprights. It passes through and is pressed and fixed by the U-shaped steel bar 2. The installation method is both stable and convenient for subsequent adjustment or disassembly. In practice, the open end of the U-shaped steel bar is embedded downward in the concrete floor slab 12. Generally, there are two U-shaped steel bars. An appropriate amount of wedge-shaped wooden blocks are inserted between the U-shaped steel bars and the I-beam 1 to prevent the I-beam 1 from loosening and to ensure the stability of the cantilevered scaffold. The end of the I-beam 1 furthest from the U-shaped reinforcing bar 2 extends to the outside of the concrete floor slab 12 and is suspended, providing sufficient cantilever length for the scaffold uprights. The positioning device installed at the suspended end of the I-beam 1 is responsible for accurately positioning and firmly fixing the scaffold uprights to the I-beam 1, preventing displacement or tilting during construction. The locking device is movably mounted on the side of the positioning device to connect the positioning device to the U-shaped reinforcing bar 2. Through the locking device, the positioning device can be firmly locked to the suspended end of the I-beam 1, ensuring the stability and safety of the scaffold uprights. The locking device and the U-shaped reinforcing bar 2 can be disassembled, and the positioning device can also be disassembled. Thus, the disassembled positioning device and locking device can be reused, reducing material waste and lowering costs. At the same time, the device has a simple structure, is quick and efficient to install, and does not require welding during installation, so it will not damage the I-beam 1.

[0028] Furthermore, the positioning device includes a fixed sleeve 11 and a positioning rod 6. The fixed sleeve 11 is a rectangular steel cylinder with one end open and the other end closed. The positioning rod 6 is detachably connected to the top surface of the fixed sleeve 11. The diameter of the positioning rod 6 is adapted to the inner diameter of the upright of the scaffold. Locking elements are provided on both sides of the fixed sleeve 11.

[0029] Specifically, such as Figure 1 As shown, the fixing sleeve 11 is a rectangular steel cylinder. The inner cavity of the fixing sleeve 11 is adapted to the size of the I-beam 1, and one end is open to allow the I-beam 1 to be inserted. The diameter of the positioning rod 6 is adapted to the inner diameter of the scaffold upright, and is generally slightly smaller than the inner diameter of the upright. The positioning rod 6 and the fixing sleeve 11 are detachably connected and are set on the top surface of the fixing sleeve 11, which facilitates quick installation or removal of the positioning rod 6 when needed, improving construction efficiency. It also makes it easy to adjust the position of the positioning rod 6 to adapt to uprights in different positions. Locking elements are set on both sides of the fixing sleeve 11, which helps to apply locking force from two directions simultaneously, ensuring the stability of the positioning rod 6 in the fixing sleeve 11. The main function of the locking elements is to further lock the fixing sleeve 11 and prevent it from loosening or falling off due to external forces during operation. By adapting the positioning rod 6 to the inner diameter of the scaffold upright, this positioning device can ensure the precise alignment of the scaffold upright during installation, improving the stability and safety of the overall structure.

[0030] Furthermore, a fixing plate 8 is welded to the bottom end of the positioning rod 6. The fixing plate 8 has through holes 13 on both sides of the positioning rod 6. Multiple threaded posts 5 that are adapted to the through holes 13 are welded to the top surface of the fixing sleeve 11 along the length direction. The threaded posts 5 are located on both sides of the axis of the positioning sleeve. After passing through the through holes 13, the threaded posts 5 are threaded to the upper end of their corresponding locking nuts 7.

[0031] Specifically, such as Figure 2 As shown, the positions of the scaffold uprights on the cantilevered parts of the I-beam 1 vary depending on different design requirements. Therefore, to accommodate uprights in different positions, a fixing plate 8 is welded to the lower end of the positioning rod 6, such as... Figure 3 As shown, the surface of the fixing plate 8 is provided with through holes 13 on both sides of the positioning rod 6. At the same time, two sets of threaded posts 5 are welded to the surface of the flange plate of the I-beam 1. Each set of threaded posts 5 has multiple threaded posts 5 and is evenly distributed along the axis of the I-beam 1. The two sets of threaded posts 5 are located on both sides of the axis of the I-beam 1, and the threaded posts 5 on both sides correspond to each other. The threaded posts 5 can be inserted into the through holes 13. When it is necessary to adjust the position of the positioning rod 6, the two through holes 13 on the fixing plate 8 can be connected with different threaded posts 5, and then the locking nut 7 can be tightened to adjust the position of the positioning rod. It should be noted that the distance between the two through holes 13 should be greater than the diameter of the upright to avoid interference between the upright and the positioning rod 6.

[0032] Furthermore, the locking component is a steel wire rope 4, one end of which is movably connected to the side wall of the fixed sleeve 11, and the other end is detachably connected to the U-shaped steel bar 2.

[0033] Furthermore, one end of the wire rope 4 is connected to a tensioner 3, and one end of the tensioner 3 has a hook that connects to the U-shaped steel bar 2.

[0034] Furthermore, a fixing ring 9 for connecting the wire rope 4 is welded to the side wall of the fixing sleeve 11. The end of the wire rope 4 away from the tensioner 3 passes through the fixing ring 9 and is fixed by the wire rope buckle 10.

[0035] Furthermore, the fixing ring 9 is formed by bending steel bars.

[0036] Furthermore, the tensioner 3 is made of stainless steel turnbuckle.

[0037] Specifically, such as Figure 1 As shown, the wire rope 4 achieves the fastening between the fixed sleeve 11 and the U-shaped reinforcing bar 2 through the connection at both ends. The wire rope 4 has good flexibility and load-bearing capacity, and can adapt to the locking requirements of different shapes and angles. One end of the wire rope 4 is movably connected to the fixing ring 9 on the side wall of the fixed sleeve 11. The fixing ring 9 is welded to the side wall of the fixed sleeve 11 and is used to connect the wire rope 4. The end of the wire rope 4 away from the tensioner 3 passes through the fixing ring 9, then bends into a loop, and is then locked and fixed to the wire rope 4 through the wire rope buckle 10, thereby ensuring the stability of the wire rope 4 on the fixed sleeve 11. The other end is detachably connected to the U-shaped reinforcing bar 2. The tensioner 3 is a stainless steel turnbuckle from Xinlang Stainless Steel Company. This product is available on the market. One end of the tensioner 3 has a hook (not shown in the figure) that connects to the U-shaped rebar 2. The hook can directly hook the U-shaped rebar 2, making it easy to connect the wire rope 4 to the U-shaped rebar 2. The other end allows the tension of the wire rope 4 to be adjusted by rotating the turnbuckle, achieving a stable locking effect. The combination of the wire rope 4 and the tensioner 3 provides flexible and large locking capacity. By adjusting the tension of the tensioner 3, the fixing sleeve 11 and the U-shaped rebar 2 can be easily fastened, preventing the fixing sleeve 11 from loosening or falling off, thereby ensuring the accuracy of the positioning rod 6.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
