Description

Technical Field

[0001] This invention relates to the technical field of concrete poles, and in particular to a crack-resistant, internally reinforced concrete pole. Background Technology

[0002] Concrete poles, also known as cement poles, are columnar poles made primarily of reinforced concrete. They are mainly used for erecting power and communication lines, replacing traditional wooden and iron poles.

[0003] Existing technology products still have the following defects in practical applications: most concrete poles have simple reinforcement structures and few reinforcements, resulting in insufficient overall structural strength, poor resistance to deformation and stress, and are prone to cracking and damage when subjected to external pressure, tension, and changes in environmental temperature. They also have a short service life, are difficult to align on-site, have poor fixing effect, low assembly efficiency, and are prone to displacement and loosening at splices, resulting in insufficient connection firmness. Summary of the Invention

[0004] Therefore, the present invention provides a crack-resistant reinforced concrete pole.

[0005] The present invention provides a crack-resistant reinforced concrete pole, which adopts the following technical solution: A crack-resistant reinforced concrete pole includes a supporting body, a mounting positioning plate fixedly connected to the bottom surface of the supporting body, a connecting block fixedly connected to the upper surface of the supporting body, and a nut fixedly connected to the side surface of the connecting block.

[0006] The inner ring surface of the nut is fitted with a threaded rod, and the outer ring surface of the threaded rod is fitted with an upper mating plate.

[0007] A concrete rod body is fixedly connected to the upper surface of the upper docking base plate. A docking collar is fitted onto the outer ring surface of the concrete rod body. A positioning rod is fixedly connected to the upper surface of the docking collar. A protective collar is fitted onto the outer ring surface of the concrete rod body.

[0008] Optionally, the inner surface of the protective collar is provided with a fitting opening, and the size of the fitting opening and the concrete pole body are matched. The fitting opening allows the protective collar to fit tightly on the outside of the concrete pole body, making assembly simple and convenient. It can provide comprehensive protection for the outer wall of the pole body, reduce damage to the surface of the pole body caused by external impact, friction and sun and rain, and delay surface aging and spalling.

[0009] Optionally, the inner surface of the concrete pole body is provided with reinforcing steel bars, and there are multiple reinforcing steel bars. The multiple sets of reinforcing steel bars constitute an internal reinforcement structure, which can significantly improve the overall structural strength, bending and tensile performance of the concrete pole body, effectively disperse the internal stress of the pole body, avoid cracking and breakage due to load, temperature difference and external force, and improve the safety and durability of the product.

[0010] Optionally, the nut is connected to the receiving body through a connecting block, and the connecting blocks are symmetrically arranged with the vertical center line of the nut as the axis of symmetry. The symmetrically arranged connecting blocks and nut structure are subjected to uniform force, which can ensure that the connection point is subjected to balanced force during the splicing operation of the rod, prevent local stress concentration, make the connection between the upper and lower rods more stable, and prevent the occurrence of displacement or loosening.

[0011] Optionally, the upper surface of the positioning rod is provided with a positioning opening, and there are multiple positioning openings. The multiple positioning openings can be used as external fixing points to facilitate the subsequent laying of cables, the addition of auxiliary accessories, and the auxiliary positioning connection between multiple poles, thereby expanding the installation adaptability and usage functions of the pole.

[0012] Optionally, the upper surface of the mounting positioning piece is provided with a through-hole, and there are multiple mounting openings arranged around the mounting positioning piece as the center point. The multiple mounting openings arranged around the center point make it easy to use fasteners to firmly lock the bottom of the pole to the foundation and base. The installation points are reasonably distributed, the fixing force is even, and the overall installation stability of the pole is greatly improved, making it less likely to tip over due to strong winds and external impacts.

[0013] Optionally, the positioning rod is connected to the concrete pole body through the docking collar, and the positioning rod is arranged around the docking collar as the center point. The surrounding positioning rod can form a multi-point limiting structure, which plays a role in precise alignment and guiding and limiting when assembling multiple pole segments, reducing the assembly difficulty and ensuring the coaxiality and structural integrity of the entire pole after splicing.

[0014] In summary, the present invention has the following beneficial technical effects: 1. This invention forms an internally reinforced structure by using multiple sets of reinforcing steel bars, which greatly improves the overall structural strength and resistance to deformation, effectively resists the stress caused by external forces such as pulling, squeezing and environmental temperature differences, significantly reduces the risk of cracking of the pole, and extends its service life; at the same time, the bottom is provided with an installation positioning piece with multiple sets of installation openings, which facilitates quick on-site positioning and fixed installation, and has high assembly convenience.

[0015] 2. This invention uses a splicing structure of docking blocks, nuts and threaded rods, combined with docking collars and positioning rods, to achieve precise docking and positioning of multiple pole sections, resulting in a strong connection and high alignment accuracy. The externally fitted protective collar can protect the surface of the pole, reducing impact and wear damage, and further ensuring the overall stability of the pole in use.

[0018] The following is in conjunction with the appendix Figures 1-5 The present invention will be further described in detail below. The technical solutions of the embodiments of the present invention will be clearly described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0019] This invention discloses a crack-resistant, internally reinforced concrete utility pole. For example... Figures 1-5 As shown, it includes a receiving body 1, a mounting positioning piece 2 is fixedly connected to the bottom surface of the receiving body 1, a docking block 11 is fixedly connected to the upper surface of the receiving body 1, a nut 12 is fixedly connected to the side surface of the docking block 11, and a threaded rod 13 is inserted into the inner ring surface of the nut 12 for limiting.

[0020] In this embodiment, the inner surface of the protective collar 7 is provided with a fitting opening 6, and the fitting opening 6 and the concrete pole body 5 are matched in size. The fitting opening 6 allows the protective collar 7 to fit tightly on the outside of the concrete pole body 5, making assembly simple and convenient. It can provide comprehensive protection for the outer wall of the pole, reducing damage to the surface of the pole caused by external impact, friction, and sun and rain, and delaying surface aging and spalling. The inner surface of the concrete pole body 5 is provided with reinforcing steel bars 14, and there are multiple reinforcing steel bars 14. The multiple sets of reinforcing steel bars 14 constitute an internal reinforcement structure, which can significantly improve the overall structural strength, bending and tensile performance of the concrete pole body 5, effectively disperse the internal stress of the pole, and avoid cracking and breakage due to load, temperature difference, and external force, thereby improving the safety and durability of the product.

[0021] like Figure 1-5 As shown, based on Embodiment 1, the present invention provides a technical solution: preferably, the outer ring surface of the threaded rod 13 is fitted with an upper mating base plate 4, and the upper surface of the upper mating base plate 4 is fixedly connected to a concrete rod body 5.

[0022] In this embodiment, the nut 12 is connected to the receiving body 1 through the docking block 11. The docking block 11 is symmetrically arranged with the vertical center line of the nut 12 as the axis of symmetry. The symmetrically arranged docking block 11 and the nut 12 structure are subjected to uniform force, which can ensure that the connection point is subjected to balanced force during pole splicing, prevent local stress concentration, and make the connection between the upper and lower poles more stable and less prone to displacement or loosening. The upper surface of the positioning rod 9 is provided with a positioning opening 10, and there are multiple positioning openings 10. The multiple positioning openings 10 can be used as external fixing points to facilitate the subsequent laying of cables, the addition of auxiliary accessories, and the auxiliary positioning connection between multiple poles, thus expanding the installation adaptability and usage function of the pole.

[0023] like Figure 1-5 As shown, based on Embodiment 1, the present invention provides a technical solution: preferably, a connecting collar 8 is fitted onto the outer ring surface of the concrete pole body 5, a positioning rod 9 is fixedly connected to the upper surface of the connecting collar 8, and a protective collar 7 is fitted onto the outer ring surface of the concrete pole body 5.

[0024] In this embodiment, the upper surface of the mounting positioning piece 2 is provided with a through-hole mounting opening 3, and there are multiple mounting openings 3 arranged around the mounting positioning piece 2 as the center point. The multiple mounting openings 3 arranged around the center point facilitate the use of fasteners to firmly lock the bottom of the pole to the foundation and base. The installation points are reasonably distributed, the fixing force is even, which greatly improves the overall installation stability of the pole and makes it less likely to tip over due to strong winds and external impacts. The positioning rod 9 is connected to the concrete pole body 5 through the docking collar 8, and the positioning rod 9 is arranged around the docking collar 8 as the center point. The surrounding positioning rod 9 can form a multi-point limiting structure, which plays a role in precise alignment and guiding and limiting when assembling multiple pole segments, reducing the assembly difficulty and ensuring the coaxiality and structural integrity of the entire pole after splicing.

[0025] The implementation principle of one embodiment of the present invention is as follows: Prepare the receiving body 1, pass the matching fasteners through the installation openings 3 arranged around the mounting positioning piece 2, fix the receiving body 1 as a whole on the foundation base, and complete the bottom foundation positioning installation. Take the connecting block 11, nut 12, and threaded rod 13, fix the symmetrically arranged connecting block 11 on the upper end face of the receiving body 1, assemble the nut 12 on the side of the connecting block 11, and then insert the threaded rod 13 into the nut 12. The upper docking base plate 4 is sleeved on the outside of the threaded rod 13, so that the upper docking base plate 4 is aligned and fits with the upper end of the receiving body 1. The threaded rod 13 and nut 12 are tightened to lock and fix the two sections of the structure. On the outside of the concrete rod body 5 above the upper docking base plate 4, the protective collar 7 is sleeved into place through the sleeve opening 6, so that the protective collar 7 fits tightly against the outer wall of the concrete rod body 5, and the surface protection assembly of the rod body is completed. A connecting collar 8 is fitted on the outside of the concrete pole body 5. The positioning rod 9 surrounding the connecting collar 8 is used for guidance and limiting to ensure the coaxiality of the structure. With the help of the positioning opening 10 at the top of the positioning rod 9, the installation of cables and external accessories or the positioning of multiple pole sections can be completed. After the overall assembly is completed, the stress is shared by multiple reinforcing steel bars 14 inside the concrete pole body 5, which resist the influence of external forces and temperature differences during long-term outdoor use and prevent the pole body from cracking.

[0026] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
