Description

Technical Field

[0001] This utility model relates to the field of building materials technology, specifically to a compression-resistant ultra-high performance concrete pole. Background Technology

[0002] Concrete poles are widely used as supporting structures in fields such as power transmission, communication engineering, and municipal construction. They need to withstand multiple forces, including their own weight, external loads (such as wind and snow loads), and the weight of installation accessories, over a long period of time. Therefore, compressive strength and structural stability are the core indicators to ensure their service life and safe use.

[0003] In existing technologies, the reinforcement methods for concrete poles are mainly divided into two categories: internal reinforcement and external wrapping reinforcement. Internal reinforcement often uses a structure in which a single ring bar is tied or welded to the vertical bar. During the pouring process, the reinforcement is prone to displacement and deformation, resulting in uneven strength distribution inside the concrete pole and limited compressive strength. External reinforcement often uses integral sleeves, spiral reinforcement strips, or welded ring hoops. These structures have obvious drawbacks: integral sleeves are inconvenient to install and disassemble and are difficult to adapt to concrete poles of different lengths; spiral reinforcement strips have limited circumferential restraint and insufficient vertical support capacity; welded ring hoops can damage the surface of the concrete pole and cannot be reused after disassembly, resulting in high maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a compression-resistant, ultra-high performance concrete pole to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A compressive-resistant ultra-high-performance concrete pole includes a concrete pole and flanges fixedly connected to both ends of the concrete pole. It also includes a compressive-resistant reinforcement assembly sleeved on the outer wall of the concrete pole and an internal reinforcing rib assembly inside the concrete pole, wherein: The compressive reinforcement component includes a reinforcing hoop and several hoop reinforcing ribs. The reinforcing hoop is composed of two sets of semi-hoops connected end to end, and the two sets of semi-hoops are movably sleeved on the outer wall of the concrete pole. The several hoop reinforcing ribs are distributed in a ring along the vertical axis of the concrete pole. The inner wall of the reinforcing hoop is provided with a hoop-in-place arc groove for limiting the position of the hoop reinforcing ribs. The outer wall of the concrete pole is provided with a vertical arc groove. The built-in reinforcing rib group includes an outer ring rib and an inner ring rib. The inner wall of the outer ring rib is fitted with an outer reinforcing vertical rib, and the inner wall of the inner ring rib is fitted with an inner reinforcing vertical rib. The outer walls of the outer ring rib and the inner ring rib are movably engaged with a limit plate.

[0006] A further improvement of this utility model is that the outer wall of the ring hoop reinforcing bar is movably connected to the inner wall of the vertical arc groove and the ring hoop's built-in arc groove, and the ring hoop reinforcing bar is located between the reinforcing ring hoop and the concrete rod.

[0007] A further improvement of this utility model is that: the outer wall of the concrete pole is provided with an external ring groove for fitting the reinforcing ring hoop, the reinforcing ring hoop is movably sleeved on the inner wall of the external ring groove, and an upper positioning block and a lower positioning block are fixedly connected to the inner wall of the reinforcing ring hoop, with the upper positioning block located above the lower positioning block.

[0008] A further improvement of this utility model is that the top of the upper positioning block abuts against the top of the inner wall of the outer annular groove, and the bottom surface of the lower positioning block abuts against the bottom of the inner wall of the outer annular groove.

[0009] A further improvement of this utility model is that: the outer wall of the limiting plate is provided with a slot, and the outer annular rib and the inner annular rib are both movably engaged with the inner wall of the slot.

[0010] A further improvement of this utility model is that: both the upper and lower ends of the concrete pole are fixedly connected to flanges, and the top of the ring hoop reinforcing rib abuts against the bottom surface of the flange.

[0011] A further improvement of this utility model is that the beginning and end of the two sets of semi-circular hoops are detachably fixedly connected by fastening bolts.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. This utility model provides a compression-resistant ultra-high performance concrete pole. The internal reinforcing bar group adopts a double-layer three-dimensional structure with outer and inner ring bars combined with outer and inner reinforcing vertical bars, respectively. With the lateral limitation of the V-shaped limiting plate, the internal structural strength and casting stability of the concrete pole are greatly improved. The external compression-resistant reinforcement component forms a double compression protection through the vertical support of the ring reinforcing bar and the circumferential constraint of the reinforcing ring, effectively dispersing the external load borne by the concrete pole and avoiding cracking and deformation caused by local stress concentration.

[0013] 2. This utility model provides a compression-resistant ultra-high performance concrete pole. The reinforcing hoop adopts a two-set half-hoop splicing structure, which can be detached and fixed by fastening bolts. Assembly and disassembly can be completed without complicated tools.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] The present invention will be further described in detail below with reference to embodiments: Example 1

[0018] like Figure 1-5 As shown, this utility model provides a compressive-resistant ultra-high performance concrete pole, including a concrete pole 1 and flanges 3 fixedly connected to both ends of the concrete pole 1, and also includes a compressive-resistant reinforcement component 2 sleeved on the outer wall of the concrete pole 1 and an internal reinforcing bar group 10 inside the concrete pole 1, wherein: like Figure 2 as well as Figure 3 As shown, the compressive strengthening component 2 includes a reinforcing hoop 6 and several hoop reinforcing ribs 18. The reinforcing hoop 6 consists of two sets of semi-hoops connected end to end, and the two sets of semi-hoops are movably sleeved on the outer wall of the concrete rod 1. Several hoop reinforcing ribs 18 are distributed in a ring along the vertical axis of the concrete rod 1. The inner wall of the reinforcing hoop 6 is provided with a hoop-in-place arc groove 7 for limiting the hoop reinforcing ribs 18. The outer wall of the concrete rod 1 is provided with a vertical arc groove 5.

[0019] The outer wall of the hoop reinforcing bar 18 is movably connected to the inner wall of the vertical arc groove 5 and the inner arc groove 7 of the hoop, and the hoop reinforcing bar 18 is located between the reinforcing hoop 6 and the concrete rod 1.

[0020] The outer wall of the concrete pole 1 is provided with an external ring groove 4 for fitting the reinforcing ring 6. The reinforcing ring 6 is movably fitted into the inner wall of the external ring groove 4. The inner wall of the reinforcing ring 6 is fixedly connected with an upper positioning block 8 and a lower positioning block 9, with the upper positioning block 8 located above the lower positioning block 9.

[0021] The top of the upper positioning block 8 abuts against the top of the inner wall of the outer ring groove 4, and the bottom surface of the lower positioning block 9 abuts against the bottom of the inner wall of the outer ring groove 4.

[0022] Flanges 3 are fixedly connected to both the upper and lower ends of the concrete pole 1, and the top of the hoop reinforcing rib 18 abuts against the bottom surface of the flange 3.

[0023] Both ends of the two sets of semi-circular hoops are detachably fixedly connected by fastening bolts 17.

[0024] In this embodiment, the number and length of the reinforcing ribs 18 and the installation position of the reinforcing ribs 6 can be flexibly adjusted according to the length of the concrete pole 1 and the working conditions to adapt to the compressive strength requirements of different scenarios. The setting of the upper positioning block 8 and the lower positioning block 9 avoids the lateral compressive force on the reinforcing ribs 18 when the reinforcing ribs 6 are fixed, ensuring the vertical support effect. The limiting plate 15 limits the outer ring ribs 11 and the inner ring ribs 12 to the same horizontal plane through the slot 16, which not only improves the structural stability of the built-in reinforcing rib group 10, but also simplifies the reinforcement positioning process during concrete pouring. Example 2

[0025] like Figure 3 as well as Figure 4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the built-in reinforcing rib group 10 includes an outer annular rib 11 and an inner annular rib 12. The inner wall of the outer annular rib 11 is sleeved with an outer reinforcing vertical rib 13, and the inner wall of the inner annular rib 12 is sleeved with an inner reinforcing vertical rib 14. The outer walls of the outer annular rib 11 and the inner annular rib 12 are movably engaged with a limiting plate 15.

[0026] The outer wall of the limiting plate 15 is provided with a slot 16, and the outer annular rib 11 and the inner annular rib 12 are movably engaged with the inner wall of the slot 16.

[0027] In this embodiment, the external compressive reinforcement component 2 forms a complete ring groove structure with the vertical arc groove 5 and the built-in arc groove 7 of the ring hoop, which realizes full-circumference limiting and covering of the ring hoop reinforcing rib 18 to prevent it from shifting or falling off; the built-in reinforcing rib group 10 works together with the external compressive reinforcement component 2 to jointly improve the overall structural strength and deformation resistance of the concrete pole 1 from both the inside and outside, and extend its service life.

[0028] The working principle of this compressive-resistant ultra-high performance concrete pole will be explained in detail below: like Figure 1-5 As shown, during the prefabrication stage of the concrete pole 1, the built-in reinforcing bar group 10 is first assembled: the outer ring bar 11 is sleeved to fix the outer reinforcing vertical bar 13, and the inner ring bar 12 is sleeved to fix the inner reinforcing vertical bar 14, forming an inner and outer double-layer ring and vertical three-dimensional reinforcement structure; then, the V-shaped limiting plate 15, viewed from above, is used to clamp and limit the outer ring bar 11 and the inner ring bar 12 to the same horizontal plane through the slot 16 opened at its top corner, ensuring that the built-in reinforcing bar group 10 will not shift during the concrete pouring process, thus providing basic structural strength for the concrete pole 1.

[0029] After the concrete pole 1 is formed, the flanges 3 at its upper and lower ends are used as installation references to fix the concrete pole 1 to the designated installation position.

[0030] The assembly of the external compressive reinforcement component 2 can be carried out as needed according to the length of the concrete pole 1 and the working conditions: First, the hoop reinforcement 18 is inserted into the vertical arc groove 5 on the outer wall of the concrete pole 1, so that the upper and lower ends of the hoop reinforcement 18 abut against the flanges 3 on the upper and lower sides of the concrete pole 1, forming a vertical support frame; then, the reinforcement hoop 6 composed of two sets of half hoops is fitted into the outer ring groove 4 on the outer wall of the concrete pole 1. The hoop reinforcement 18 is fitted and engaged by the inner arc groove 7 of the inner wall of the reinforcement hoop 6, and the vertical arc groove 5 forms a complete ring groove structure, which fully limits and covers the hoop reinforcement 18 to prevent its lateral displacement.

[0031] The two sets of semi-circular hoops are fixed end to end with fastening bolts 17 to complete the assembly of the reinforcing hoop 6. At this time, the upper positioning block 8 on the inner wall of the reinforcing hoop 6 abuts against the top of the inner wall of the outer ring groove 4, and the lower positioning block 9 abuts against the bottom of the inner wall of the outer ring groove 4, ensuring that the reinforcing hoop 6 will not generate lateral compressive force on the hoop reinforcing rib 18 when it is fixed, thus ensuring the vertical compressive support effect of the hoop reinforcing rib 18.

[0032] For a long concrete pole 1, on the basis of the fixed reinforcing ring 6, the upper positioning block 8 can be used as the support reference, and segmented ring reinforcing ribs 18 can be installed in the vertical arc groove 5. Then, another set of reinforcing rings 6 can be sleeved on the middle position of the ring reinforcing ribs 18 for fixation, so as to achieve the matching of the number and length of the ring reinforcing ribs 18 with the length of the concrete pole 1, and maintain the uniform support force of the ring reinforcing ribs 18 throughout the process.

[0033] The built-in reinforcing bar group 10 enhances the internal crack resistance and compressive strength of the concrete pole 1 through the combination of inner and outer double-layer ring bars and vertical bars; the external compressive strengthening component 2 forms a dual compressive structure of "vertical support and circumferential restraint" through the vertical support of the ring reinforcing bar 18 and the circumferential restraint of the reinforcing ring 6.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
