Description

Technical Field

[0001] This utility model relates to the field of municipal construction technology, specifically a reinforced base for cement poles. Background Technology

[0002] Concrete pole reinforcement bases are structures used to support infrastructure such as utility poles, signal towers, streetlights, traffic signs, and billboards. With the rapid development of urbanization and modernization, the demand for infrastructure such as power supply, communication networks, and traffic management is increasing. Concrete pole reinforcement bases provide stable and safe support for these infrastructures, ensuring their normal operation and long-term reliability. Since these infrastructures are usually located in public areas, their stability and safety are crucial. Concrete pole reinforcement bases must be able to withstand the effects of various natural and human factors, such as wind loads, snow loads, earthquakes, and traffic impacts, to prevent accidents.

[0003] The installation method for reinforced concrete pole bases typically includes the following steps to ensure structural stability and safety: Preparation: Clean the installation area, ensuring the ground is flat, firm, and free of debris and standing water. Determine the specific location of the base based on design drawings and site conditions. Excavation: Dig a foundation pit of appropriate size and depth according to design requirements. The pit should be large enough to accommodate the base and necessary reinforcement materials. Base Placement: Place the base in the foundation pit, ensuring it is level and accurately positioned. If necessary, use a level for calibration. Adjustment and Fixing: If adjustments are needed, use jacks or other tools for fine-tuning to ensure the base is level and vertical. Place reinforcing bars or anchors around the base to ensure a secure connection between the base and the ground. Pouring: Pour concrete... Concrete pouring: Pour concrete around the base and between the reinforcing bars. The concrete should fully fill the foundation pit and ensure there are no gaps. During pouring, use tools such as vibrators to ensure the concrete is dense and avoid air bubbles and voids. Concrete curing: After pouring, properly cure the concrete, such as by watering and covering with damp cloths, to prevent excessive drying and cracking. The curing time depends on the type of concrete and environmental conditions, usually requiring several days to a week. Inspection and acceptance: After the concrete has completely cured, check the levelness, verticality, and overall stability of the base and make necessary adjustments to ensure the base meets design requirements and usage standards. Cement pole installation: After the base has completely cured and passed inspection, install the cement poles, accurately placing them on the base and securing them.

[0004] The installation of existing cement pole bases requires digging a very large foundation pit, which occupies a large area and has a significant impact on the surrounding environment. In addition, the installation of the base is very time-consuming and labor-intensive, which is a waste of manpower and time. Therefore, we need to design a cement pole base that is easy to install and has less impact on the surrounding environment. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a reinforced base for cement poles to solve the technical problems of traditional bases being time-consuming and labor-intensive to install and having a significant impact on the surrounding environment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cement pole reinforced base, comprising a protective outer shell, an inner protective shell installed inside the protective outer shell, a limiting ring provided at the top of the inner protective shell, a limiting plate provided at the bottom of the inner protective shell, and a plurality of sliding grooves provided on the limiting plate, a slider slidably engaging in each of the sliding grooves, and an extension plate connected to the bottom of each slider, with each extension plate cooperating with each other.

[0007] By adopting the above technical solution, a pit matching the size of the protective shell is excavated, the device is placed in the pit, and the limiting ring is rotated to make the limiting plate at the bottom of the inner protective shell rotate, which drives the slider in the slide groove to slide outward along the slide groove, and finally makes the extension plate extend outward, thus completing the rapid fixation of the device.

[0008] The present invention is further configured such that a plurality of positioning holes and fixing holes are sequentially opened at the top end of the limiting ring, and a limiting groove is opened inside the outer wall of the protective shell to cooperate with the positioning holes and fixing holes and penetrate through the upper and lower ends of the protective shell.

[0009] By adopting the above technical solution, the cement pole is placed inside the protective inner shell and fixed by fixing holes and matching fixing devices.

[0010] The present invention is further configured such that a threaded cylinder is slidably connected in a limiting groove that mates with the positioning hole, and a threaded post that penetrates into the bottom of the threaded cylinder is threaded through the bottom of the threaded cylinder. Each extension plate does not interfere with the corresponding threaded post. A washer is connected to the bottom of the interior of each positioning hole, and a spring is connected to the top surface of the washer. A bolt is connected to the top of the spring, and each bolt moves through the corresponding washer. Each bolt mates with the corresponding washer.

[0011] By adopting the above technical solution, after the extension plate is unfolded, the bolt in the positioning hole is aligned with the corresponding threaded cylinder, and the bolt is pressed down, so that the spring between the washer and the bolt is compressed, the bolt contacts the threaded cylinder, the bolt is rotated, and finally the bolt thread is inserted into the threaded cylinder and drives the threaded cylinder to rotate, which drives the threaded column in the threaded cylinder to extend out spirally, completing the secondary fixation of the device. The connection between the bolt and the threaded cylinder can prevent the extension plate from retracting.

[0012] The present invention is further configured such that a positioning plate is installed at the bottom of the protective shell, and each positioning plate does not interfere with the corresponding threaded post.

[0013] By adopting the above technical solution, the positioning plate is used to assist in the placement and positioning of the device.

[0014] The present invention is further provided that the outer periphery of the protective shell is provided with a number of supporting ribs.

[0015] By adopting the above technical solution, the supporting ribs are used to strengthen the protective shell and increase the contact area between the device and the ground, thereby improving the stability of the device.

[0016] In summary, the present invention has the following main advantages:

[0017] This invention rotates the limiting ring, causing the limiting plate at the bottom of the protective inner shell to rotate, which in turn drives the slider in the groove to slide outward along the groove, ultimately causing the extension plate to extend outward and complete the rapid fixation of the device. After the extension plate is extended, the bolt is pressed down and rotated, finally allowing the bolt thread to be inserted into the threaded cylinder and causing the threaded column in the threaded cylinder to extend outward, completing the secondary fixation of the device. Furthermore, the connection between the bolt and the threaded cylinder can prevent the extension plate from retracting. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The embodiments of this utility model will be described below based on its overall structure.

[0026] A type of reinforced base for cement poles, such as Figure 1-5 As shown, the device includes a protective outer shell 1, inside which a protective inner shell 2 is installed. A limit ring 3 is provided at the top of the protective inner shell 2, and a limit plate 14 is provided at the bottom of the protective inner shell 2. The limit plate 14 has several sliding grooves 15, in which a slider 16 is slidably engaged. The bottom of each slider 16 is connected to an extension plate 17. The extension plates 17 cooperate with each other to excavate a pit that matches the size of the protective outer shell 1. The device is placed in the pit, and the limit ring 3 is rotated, causing the limit plate 14 at the bottom of the protective inner shell 2 to rotate, which drives the slider 16 in the sliding groove 15 to slide outward along the sliding groove 15. Finally, the extension plate 17 extends outward, completing the rapid fixation of the device.

[0027] The top of the limiting ring 3 is provided with a number of positioning holes 4 and fixing holes 5. The outer wall of the protective shell 1 is provided with a limiting groove 9 that matches the positioning holes 4 and fixing holes 5 and passes through the upper and lower ends of the protective shell 1. The cement rod is placed into the inner protective shell 2 and fixed by the fixing holes 5 and the matching fixing device.

[0028] A threaded cylinder 10 is slidably connected in the limiting groove 9 that mates with the positioning hole 4. The bottom end of the threaded cylinder 10 is threaded through a threaded post 11 that penetrates into the inside of the threaded cylinder 10. Each extension plate 17 does not interfere with the corresponding threaded post 11. A washer 7 is connected to the bottom end of the inside of each positioning hole 4. A spring 8 is connected to the top surface of the washer 7. A bolt 6 is connected to the top of the spring 8. Each bolt 6 movably passes through the corresponding washer 7. Each bolt 6 mates with the corresponding washer 7. After the extension plate 17 is unfolded, the bolt 6 in the positioning hole 4 is aligned with the corresponding threaded cylinder 10. The bolt 6 is pressed down, which compresses the spring 8 between the washer 7 and the bolt 6. The bolt 6 contacts the threaded cylinder 10. The bolt 6 is rotated, and finally the bolt 6 is threadedly inserted into the threaded cylinder 10 and drives the threaded cylinder 10 to rotate. This causes the threaded post 11 inside the threaded cylinder 10 to extend spirally, completing the secondary fixation of the device. The connection between the bolt 6 and the threaded cylinder 10 can prevent the extension plate 17 from retracting.

[0029] The bottom of the protective housing 1 is equipped with a positioning plate 13. Each positioning plate 13 does not interfere with the corresponding threaded post 11. The positioning plate 13 is used for the placement and positioning of the auxiliary device.

[0030] The protective shell 1 is equipped with several supporting ribs 12. The supporting ribs 12 are used to strengthen the protective shell 1 and increase the contact area between the device and the ground, thereby improving the stability of the device.

[0031] Working principle: A pit matching the size of the protective shell 1 is excavated, and the device is placed in the pit. The positioning plate 13 is used to assist in the placement and positioning of the device. The support rib 12 is used to strengthen the protective shell 1 and increase the contact area between the device and the ground, thereby improving the stability of the device. Rotating the limiting ring 3 causes the limiting plate 14 at the bottom of the inner protective shell 2 to rotate, driving the slider 16 in the slide groove 15 to slide outward along the slide groove 15. Finally, the extension plate 17 extends outward, completing the rapid fixation of the device. After the extension plate 17 is unfolded, the bolt 6 in the positioning hole 4 and the corresponding bolt 6 are engaged. Align the threaded cylinder 10 with the bolt 6 and press it downwards, compressing the spring 8 between the washer 7 and the bolt 6. The bolt 6 then contacts the threaded cylinder 10. Rotate the bolt 6 until the threaded bolt 6 is inserted into the threaded cylinder 10 and rotates the threaded cylinder 10, causing the threaded post 11 inside the threaded cylinder 10 to extend spirally, completing the secondary fixation of the device. The connection between the bolt 6 and the threaded cylinder 10 can prevent the extension plate 17 from retracting. At this point, the cement pole base is installed. Place the cement pole into the protective inner shell 2 and fix it through the fixing hole 5 and the matching fixing device to complete the installation of the cement pole.
