Description

Technical Field

[0001] This utility model relates to an I-beam cantilever positioning pile. Background Technology

[0002] In construction engineering, H-beams are frequently used as support structures for cantilever scaffolding and steel structure installation. Traditionally, the piles on H-beams are connected by a threaded rod welded to a positioning component, allowing for rapid installation. However, in practical use, since the pile itself is a support component, simply connecting it to the threaded rod is insufficient to guarantee its stability. Furthermore, since the rod is welded to the positioning component, its breakage or other issues could cause the pile to detach, leading to the collapse of the entire support system. Therefore, based on actual site conditions, the inventors designed a novel type of cantilevered H-beam positioning pile. Utility Model Content

[0003] This utility model provides an I-beam cantilever positioning pile, which can effectively solve the above problems.

[0004] This utility model is implemented as follows:

[0005] An I-beam cantilever positioning pile, including

[0006] I-beam steel body;

[0007] Positioning components;

[0008] A fixing component; the fixing component includes a fixing base, one end of which is provided with a plug for installing a pile body, an anti-sway member at one end of the plug is threadedly connected to the pile body, and a long screw for limiting the anti-sway member and the pile body is provided at one end of the fixing base and on both sides of the plug.

[0009] The beneficial effects of this utility model are:

[0010] (1) This utility model creatively achieves rapid and accurate positioning and rigid connection of the pile body through the coordinated cooperation of the plug-in component, the anti-sway component and the long screw. Its beneficial effects are as follows: the plug-in structure effectively restricts the radial displacement and rotation of the pile body, the anti-sway component eliminates the axial gap through the threaded connection and provides an indication of the installation position, and the long screw that runs through multiple components applies a huge pre-tightening force, pressing the entire connection node into a rigid whole without slippage, thereby greatly enhancing the node's resistance to shear, torsion and impact, effectively preventing the pile body from loosening, swaying or rotating under dynamic load, and significantly improving the safety, stability and reliability of the cantilever support system.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0022] Reference Figure 1-4 As shown, an I-beam cantilever positioning pile includes an I-beam body 10.

[0023] The positioning component 20 provides a precise installation position for the fixing component 50. The threaded holes or smooth holes machined on it ensure that the long screw 508 can be accurately positioned. At the same time, it greatly enhances the local stiffness of the I-beam 10 at the installation point, preventing it from deforming or becoming unstable under concentrated loads. Furthermore, as an important force transmission medium, it distributes the forces from the fixing component 50 and the pile body 60 more evenly across the entire cross section of the I-beam 10, optimizing the force path and avoiding stress concentration.

[0024] Fixing component 50; fixing component 50 includes fixing base 500, one end of fixing base 500 is provided with plug connector 506 for installing pile body 60, anti-sway member 510 at one end of plug connector 506 is threadedly connected to pile body 60, and one end of fixing base 500 and both sides of plug connector 506 are provided with long screw rods 508 for limiting anti-sway member 510 and pile body 60.

[0025] The connector 506 includes a connecting part 5060, a transverse part 5062, and a fixing part 5064. When the pile body 60 is inserted into the connector 506, the second locking port 600 at the end of the pile body 60 is adapted to and engaged with the connecting part 5060. At the same time, the first locking port 5104 at the end of the mounting ring 5100 in the anti-sway member 510 is engaged with the transverse part 5062. The long screw 508 is threadedly connected to the threaded groove on the fixing part 5064, the fixing seat 500, and the positioning member 20, thereby fixing the anti-sway member 510 and the pile body 60.

[0026] Furthermore, the pile body 60 is inserted into the connecting part 5060, the anti-sway component 510 is screwed into the pile body and its first locking jaw 5104 is engaged with the transverse part 5062, and the long screw 508 passes through the fixing part 5064 and is tightened. This process achieves multi-level and multi-directional constraints.

[0027] The long screw 508 is threaded with a first nut 5080 and a second nut 5082, the size of the first nut 5080 being smaller than the size of the second nut 5082.

[0028] In one embodiment, the long screw (508) is the "final guarantee" of the entire fixing process. It bears the tension and is equivalent to a powerful "clamping bolt" that tightly clamps together the series of components, including the anti-sway component 510, the pile body 60, the plug-in component 506, the fixing seat 500, and the positioning component 20, to form a rigid whole without slippage.

[0029] Furthermore, the use of a first nut 5080 and a second nut 5082 of different sizes is a standard anti-loosening measure. The smaller first nut 5080 acts as a preload nut and is first tightened to the specified preload torque, while the larger second nut 5082 acts as a lock nut (or back nut) and is subsequently tightened, pressing against the first nut. This structure generates a huge frictional force in the threaded pair and changes the stiffness of the connection system, effectively resisting vibration and dynamic load impact during construction, preventing the long screw 508 from loosening on its own, and ensuring safety for long-term use.

[0030] The top of the mounting ring 5100 is integrally formed with an upper convex ring 5102. The upper convex ring 5102 acts as a reinforcing rib, which significantly improves the rigidity and strength of the top of the mounting ring 5100, preventing it from deforming or crushing when subjected to the huge clamping force of the long screw 508. At the same time, it provides a flat and solid clamping surface for the nut of the long screw 508 (especially the second nut 5082), so that the clamping force can be evenly distributed, further optimizing the stress state.

[0031] One end of the fixing base 500 is also formed with a positioning hole 504 for defining the plug 506, and the other end of the fixing base 500 is provided with a bolt 502, which passes through the web of the I-beam 10 and is fixed by a nut.

[0032] In one embodiment, the positioning hole 504 is a hole whose shape and size match the lower part of the connector 506. Its main function is to accurately position and fix the connector 506, prevent the connector 506 from moving or rotating within the fixing base 500, and ensure that the position of the connecting part 5060 and the transverse part 5062 relative to the entire I-beam is accurate and unchanged, thus ensuring the repeatability of each installation.

[0033] A hinge seat 30 is provided at the top of the I-beam 10, and a tension member 40 connected to the wall is provided on the hinge seat 30. The hinge seat 30 is welded to the top of the I-beam 10 near the anchoring end, providing a reliable connection point. The tension member 40 is usually a turnbuckle, one end of which is connected to the hinge seat 30, and the other end is connected to the upper building structure through a pre-embedded ring or wire rope. By adjusting the length of the turnbuckle, a downward tension can be applied to the I-beam 10. This tension generates a balancing moment opposite to the overturning moment, thereby greatly improving the safety margin of the entire cantilever system and avoiding the risk of overturning.

[0034] The anti-sway component 510 has an internal thread at its connection end with the pile body 60, and the corresponding end of the pile body 60 has a matching external thread. Specifically, the main purpose of the anti-sway component 510 is not to provide the main axial tensile force, but to tighten and eliminate the axial gap between the pile body 60 and the connector 506, ensuring that all parts fit tightly. More importantly, the mounting ring 5100 and the first locking port 5104 on its top are key to the interaction with the connector 506. By tightening the anti-sway component 510, the operator can clearly feel the first locking port 5104 engaging with the transverse part 5062, which is a clear indication of proper installation and ensures the reliability of the installation.

[0035] Working principle: First, the pile body 60 is securely installed on the web of the I-beam 10 using the bolt 502 at one end of the fixing seat 500. During installation, the end of the pile body 60 is inserted into the connector 506 of the fixing seat 500, so that the second locking port 600 at its end engages with the connecting part 5060 of the connector 506, achieving initial radial limiting. Subsequently, the anti-sway member 510 is tightened to the external thread at the end of the pile body 60 through its internal thread. During this process, the first locking port 5104 at the end of the mounting ring of the anti-sway member 510 also engages with the transverse part 5062 of the connector 506, thereby effectively preventing the pile body 60 from swaying under stress. Rotate; finally, pass the long screw 508 through the threaded holes on the fixing parts 5064, fixing seats 500 and positioning parts 20 on both sides of the plug connector 506, and lock it with the first nut 5080 and the second nut 5082 of different sizes. The double nut mechanism generates a huge preload force, pressing the anti-sway part 510, pile body 60, plug connector 506 and fixing seat 500 into a rigid whole, thereby reliably transferring the load borne by the pile body 60 to the I-beam body through the fixing assembly 50 and positioning parts 20; in addition, the top of the I-beam is connected to the wall through the hinge seat and the tensioning member, which further enhances the stability of the entire cantilever system.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
