Description

Technical Field

[0001] This utility model relates to the field of cement pole technology, and in particular to a hollow cement pole. Background Technology

[0002] Hollow concrete poles are hollow rod-shaped structures made primarily of steel reinforcement and concrete. Their hollow design reduces weight and improves bending resistance, making them common overhead line supports in industries such as power, telecommunications, and railways. The structure consists of a steel reinforcement skeleton at its core, covered with high-strength concrete, and formed into a hollow shape using a centrifugal process. During manufacturing, the skeleton structure is first erected, then custom-made cement is poured into a mold, and a centrifuge is used to rotate it at high speed, causing the cement to adhere tightly to the inner wall and solidify.

[0003] Currently, hollow cement poles in related technologies improve their shear resistance under extreme weather conditions such as strong winds by setting up double-layer steel reinforcement frames inside and outside the pole body and adding reinforcing plates and ribs inside the pole body. However, their torsional resistance is still insufficient and they are difficult to effectively cope with torsional forces. In strong wind environments, the non-uniform impact of turbulence and lateral gusts will cause the windward side of the pole body to be unbalanced. Combined with factors such as uneven icing of the conductor and eccentric load on the crossarm, torsional forces around the pole axis are easily generated. The structure such as ring stirrups and reinforcing plates has limited restraint on the oblique stress generated by torsion. Therefore, under strong winds, the pole body is at risk of cracking, breaking or even toppling due to insufficient torsional resistance. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a hollow cement pole that, through a transverse triangular support structure design, distributes the torsional force on the cement pole to the entire steel reinforcement skeleton structure, effectively improving the torsional resistance of the cement pole under complex stress conditions and enhancing the strength of the pole.

[0006] To achieve the above objectives, this utility model proposes a hollow cement pole, comprising a concrete cylinder, a connecting assembly, and a reinforcement mechanism. The reinforcement mechanism is disposed within the concrete cylinder, and the connecting assembly is located at the bottom of the concrete cylinder and connected to the reinforcement mechanism. The reinforcement mechanism includes two limiting rings, multiple shear-resistant components, torsional components, multiple main reinforcement bars, and multiple stirrups. The multiple main reinforcement bars are circumferentially distributed around the axial direction of the concrete cylinder, with both ends connected to the two limiting rings. The multiple stirrups are equidistantly sleeved around the main reinforcement bars and connected to them. The multiple shear-resistant components are equidistantly arranged along the axial direction of the concrete cylinder and correspond to the positions of the stirrups. The torsional components are circumferentially distributed around the axial direction of the concrete cylinder, and the shear-resistant components are connected to the stirrups through the multiple torsional components.

[0007] In addition, the hollow cement pole proposed above according to this utility model may also have the following additional technical features: Specifically, the shear-resistant component includes multiple reinforcing ribs, a mounting ring, and a retaining ring. The multiple reinforcing ribs are disposed within the mounting ring and are arranged in a ring. The retaining ring is provided with multiple limiting protrusions arranged in a ring. The retaining ring is disposed within the mounting ring, and the limiting protrusions are engaged with the reinforcing ribs.

[0008] Specifically, the anti-torsion assembly includes a first collar, a second collar, and a reinforcing rod. The reinforcing rod has inserts at both ends and at the corners. The inserts at the corners of the reinforcing rod are located inside the second collar, and the inserts at both ends of the reinforcing rod are located inside the first collar.

[0009] Specifically, the connecting assembly includes multiple stiffening plates, a connecting ring, and a mounting flange, wherein the multiple stiffening plates are disposed on the connecting ring and are arranged in a ring, and the connecting ring is disposed on the mounting flange.

[0010] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: This invention, by setting up an anti-shear component and utilizing the cooperation of reinforcing ribs, mounting rings, and retaining rings, can effectively resist the shear force generated by external forces, thereby enhancing the shear resistance of the cement pole. By setting up an anti-torsion component, using the triangular support system formed by the first set of rings, the second set of rings, and the reinforcing ribs, the torsional force can be distributed and transferred to the entire steel reinforcement skeleton structure, avoiding stress concentration. It effectively resists the non-uniform impact force caused by turbulence, lateral gusts, etc., as well as the torsional force caused by uneven icing of the conductor and eccentric load on the crossarm, thereby avoiding the risk of cracking, breakage, or even toppling of the pole due to insufficient torsional resistance.

[0015] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The hollow cement pole of this utility model embodiment will be described below with reference to the accompanying drawings.

[0017] like Figures 1-6 As shown in the figure, a hollow cement pole according to an embodiment of the present invention includes a concrete cylinder 1, a connecting component 5, and a reinforcement mechanism. The reinforcement mechanism is disposed inside the concrete cylinder 1, and the connecting component 5 is located at the bottom of the concrete cylinder 1 and connected to the reinforcement mechanism.

[0018] It should be noted that the reinforcement mechanism is used to enhance the overall structural strength of the hollow cement pole and improve its shear and torsional resistance, while the connecting component 5 is used to securely install the hollow cement pole.

[0019] The reinforcement mechanism includes two limiting rings 2, multiple shear-resistant components 3, anti-torsion components 4, multiple main reinforcement bars 6, and multiple stirrups 7. The multiple main reinforcement bars 6 are distributed in a ring around the axial direction of the concrete cylinder 1, and their two ends are connected to the two limiting rings 2. The multiple stirrups 7 are equidistantly sleeved on the outside of the main reinforcement bars 6 and connected to the main reinforcement bars 6. The multiple shear-resistant components 3 are equidistantly arranged along the axial direction of the concrete cylinder 1 and correspond to the positions of the stirrups 7. The anti-torsion components 4 are distributed in a ring around the axial direction of the concrete cylinder 1, and the shear-resistant components 3 are connected to the stirrups 7 through the multiple anti-torsion components 4.

[0020] It should be noted that the hollow concrete pole is constructed by the combination of multiple main reinforcing bars 6 and multiple stirrups 7, which are fixed together by welding or binding to ensure the stability of the skeleton structure. Two limiting rings 2 are welded to the main reinforcing bars 6 to limit their movement.

[0021] By combining multiple shear-resistant components 3 with anti-torsion components 4, the shear and torsional resistance of the reinforced steel frame structure can be enhanced.

[0022] The shear-resistant component 3 can provide further support within the skeleton structure, effectively resisting the shear force generated by external forces and preventing shear failure of the rod when under stress.

[0023] The anti-torsion component 4 is set between the anti-shear component 3 and the steel reinforcement cage to form a horizontal triangular support, which can distribute the torsional force to various parts of the steel reinforcement cage, avoid stress concentration and torsional failure of the bar, and effectively prevent the bar from cracking, breaking and other damages under torsional force.

[0024] In one embodiment of this utility model, such as Figures 4-6 As shown, the shear-resistant component 3 includes multiple reinforcing ribs 31, a mounting ring 33, and a retaining ring 34. The multiple reinforcing ribs 31 are arranged in a ring within the mounting ring 33. The retaining ring 34 is provided with multiple retaining protrusions 36 arranged in a ring. The retaining ring 34 is arranged in the mounting ring 33, and the retaining protrusions 36 are engaged with the reinforcing ribs 31.

[0025] It should be noted that the mounting ring 33 has a groove, the reinforcing rib 31 is set in the groove, the shape of the limiting protrusion 36 is adapted to the shape of the reinforcing rib 31, and the retaining ring 34 is fixedly installed in the mounting ring 33 by bolts. The retaining ring 34 is engaged with the reinforcing rib 31 by the limiting protrusion 36, which not only ensures the overall structural stability of the shear component 3, but also restricts the position of the reinforcing rib 31 and prevents the reinforcing rib 31 from separating from the mounting ring 33. The two ends of the reinforcing rib 31 are welded to the two limiting rings 2.

[0026] The cross-section of the reinforcing bar 31 is "T" shaped, which increases the contact area with the concrete, enhances the bonding force between the shear component 3 and the concrete, and strengthens the shear resistance. Moreover, the "T" shaped structure can better disperse and transfer the force when subjected to shear force, reduce local stress concentration, and further improve the shear resistance.

[0027] In one embodiment of this utility model, such as Figures 5-6 As shown, the anti-torsion assembly 4 includes a first collar 41, a second collar 42, and a reinforcing rod 43. The reinforcing rod 43 has inserts 44 at both ends and at the corners. The inserts 44 at the corners of the reinforcing rod 43 are located inside the second collar 42, and the inserts 44 at both ends of the reinforcing rod 43 are located inside the first collar 41.

[0028] It should be noted that the first ring 41 is fixed to the stirrup 7 by welding, and the second ring 42 is fixed to the mounting ring 33 by welding. The reinforcing rod 43 has an obtuse "V" shaped structure, and inserts 44 are welded to both ends and corners. The inserts 44 are respectively inserted into the first ring 41 and the second ring 42, thus forming a triangular support system between the stirrup 7 and the mounting ring 33.

[0029] Understandably, when the rod is subjected to torsional force, the reinforcing rod 43 can distribute and transfer the torsional force to the stirrup 7 and the mounting ring 33 through the first set of rings 41 and the second set of rings 42, and then to the entire steel reinforcement skeleton structure, so as to avoid stress concentration in a certain part and effectively prevent the concrete cylinder 1 from cracking, breaking and other damage due to torsional force.

[0030] In one embodiment of this utility model, such as Figure 3 As shown, the connecting assembly 5 includes multiple stiffening plates 51, a connecting ring 52, and a mounting flange 53. The multiple stiffening plates 51 are disposed on the connecting ring 52 and are arranged in a ring shape, and the connecting ring 52 is disposed on the mounting flange 53.

[0031] It should be noted that the connecting ring 52 is welded to the limiting ring 2 located at the bottom, the connecting ring 52 is welded to the mounting flange 53, the stiffening plate 51 is welded to the connecting ring 52, and the mounting flange 53 has multiple mounting holes to facilitate the secure installation of the hollow cement pole on the foundation by means of bolts and other connecting parts.

[0032] In practical applications, the main reinforcing bars 6 and stirrups 7 are first welded or tied to form a steel reinforcement skeleton structure. Then, the first set of rings 41 is welded to the stirrups 7, and the second set of rings 42 is welded to the mounting ring 33. The retaining ring 34 is fixedly installed in the mounting ring 33 by bolts, so that the limiting protrusion 36 is aligned with the groove on the mounting ring 33.

[0033] Next, the mounting ring 33 is placed inside the steel reinforcement cage and aligned with the position of the stirrup 7. The inserts 44 on the reinforcing rod 43 are inserted into the first set of rings 41 and the second set of rings 42 respectively, forming a triangular support system between the stirrup 7 and the mounting ring 33, and then fixed by welding.

[0034] Then, the reinforcing rib 31 is inserted into the inner groove of the mounting ring 33, and the position of the reinforcing rib 31 is limited by the limiting protrusion 36. The two limiting rings 2 are welded to the two ends of the reinforcing rib 31 and the main rib 6 respectively. Finally, the mounting flange 53 is welded to a limiting ring 2 through the connecting ring 52. At this time, the assembly of the hollow cement pole reinforcement structure is completed.

[0035] The entire structure is placed into a custom mold, and the prepared high-strength concrete is injected into the mold. A centrifuge is used to rotate the structure at high speed, causing the cement to adhere tightly to the inner wall of the mold and form a hollow concrete cylinder 1. During the concrete solidification process, the reinforcement mechanism is tightly integrated with the concrete, enhancing the overall structural strength of the hollow cement rod.

[0036] In summary, the hollow cement pole of this utility model embodiment, by setting up an anti-shear component and utilizing the cooperation of reinforcing ribs, mounting rings, and retaining rings, can effectively resist the shear force generated by external forces, thereby enhancing the shear resistance of the cement pole. By setting up an anti-torsion component and utilizing the triangular support system formed by the first set of rings, the second set of rings, and the reinforcing ribs, the torsional force can be dispersed and transferred to the entire steel reinforcement skeleton structure, avoiding stress concentration. It effectively resists the non-uniform impact force generated by turbulence, lateral gusts, etc., as well as the torsional force caused by factors such as uneven icing of the conductor and eccentric load on the crossarm, thereby avoiding the risk of cracking, breakage, or even toppling of the pole due to insufficient torsional resistance.
