Description

Technical Field

[0001] This utility model belongs to the field of poles and towers, specifically, it relates to a prefabricated pole and tower. Background Technology

[0002] With the rapid development of infrastructure such as communications, power, and meteorology, power poles, as important supporting components, are widely used in the installation of transmission lines, communication base stations, and various observation equipment. However, existing power pole structures still have some problems in their design and installation. Traditional power poles typically use a single steel pipe as a diagonal brace or supporting component. After the strut is connected to the tower body, it mainly bears axial pressure. However, in actual operation, the strut is also subjected to bending moment, especially when the tower is tall or the wind load is large. The bending moment at the tower root is prone to increase, leading to excessive stress in the tower root material, affecting the overall stability and safety. At the same time, traditional struts are relatively long and have a high slenderness ratio, which can easily lead to buckling or uneven stress, reducing the tower's load-bearing capacity.

[0003] In view of this, this utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a prefabricated tower, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A prefabricated pole tower includes: a pole tower body;

[0007] Several steel pipes are arranged in a ring around the tower body, inclined and connected to the ground. U-shaped connecting seats are pre-embedded in the ground, and the first end of the steel pipe is fixed in the U-shaped connecting seat by bolts.

[0008] The support mechanism includes a composite rod, the lower end of which is fixedly connected to a connecting foundation embedded in the ground. A connector is slidably connected to the periphery of the steel pipe, and an arc-shaped plate for the composite rod is fixedly connected to one side of the connector. The composite rod is fixed to the first arc-shaped plate by bolts.

[0009] Optionally, the combined rod is composed of several interlocking struts, each strut having a flange fixed at both ends, and adjacent flanges being fixedly connected by bolts.

[0010] Optionally, a ramp is provided between two adjacent flanges, and the opening after the two ramps are combined forms a triangular structure.

[0011] Optionally, the connector includes two second arc-shaped plates located on the surface of the steel pipe. Each second arc-shaped plate has a connecting plate fixed on both sides. The connecting plates have slots on opposite sides, and two adjacent slots are fixed to the surface of the steel pipe by bolts.

[0012] Optionally, the connecting foundation includes a vertical cylinder, with a sliding rod elastically connected inside the vertical cylinder. Several slots are opened on the periphery of the inner wall of the sliding rod, and ball-head rods are elastically connected inside the slots. Several slots for matching the ball-head rods are opened through the periphery of the vertical cylinder. The upper end of the vertical cylinder and the bottom support rod are fixed together by bolts.

[0013] Optionally, the internal space of the vertical cylinder is a T-shaped groove structure, and the slide rod is a T-shaped rod structure. A gap is left between every two adjacent slots. When the slide rod is not retracted, the end of the ball head rod fits into the gap.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] This invention designs the area below the connection point between the steel pipe and the tower body as a truss structure, enabling the strut to simultaneously withstand axial pressure and bending moment during stress. This effectively reduces the bending moment at the base of the tower body, improving the strength and stability of the tower base. Simultaneously, by setting a composite rod between the middle of the strut and the base of the tower body, the steel pipe forms a triangular stress structure with multi-point support, thereby reducing the slenderness ratio of the strut, enhancing the overall stress performance and wind resistance of the tower, and optimizing the stress distribution of the tower structure.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] Please see Figure 1-4 As shown, this embodiment provides a prefabricated tower, including a tower body 1;

[0027] Several steel pipes 2 are arranged in a ring around the tower body 1, inclined and connected to the ground. U-shaped connecting seats 3 are pre-embedded in the ground. The first end of the steel pipe 2 is fixed in the U-shaped connecting seat 3 by bolts. The steel pipe 2 can be connected to the tower periphery by welding.

[0028] The support mechanism includes a composite rod 4, the lower end of which is fixedly connected to a connecting base 5 embedded in the ground. A connector is slidably connected to the periphery of the steel pipe 2, and an arc-shaped plate for the composite rod 4 is fixedly connected to one side of the connector. The composite rod 4 is fixed to the first arc-shaped plate 6 by bolts.

[0029] This invention designs the area below the connection point between the steel pipe 2 and the tower body 1 as a truss structure, enabling the strut 7 to simultaneously withstand axial pressure and bending moment during stress, thereby effectively reducing the bending moment at the root of the tower body 1 and improving the strength and stability of the tower root. At the same time, by setting a combined rod 4 between the middle of the strut 7 and the root of the tower body 1, the steel pipe 2 forms a triangular force-bearing structure with multi-point support, thereby reducing the slenderness ratio of the strut 7, enhancing the overall stress performance and wind resistance of the tower, and optimizing the stress distribution of the tower structure.

[0030] In this embodiment, the composite rod 4 is composed of several interconnected support rods 7. Each support rod 7 has a flange 8 fixed at both ends, and adjacent flanges 8 are connected by bolts. By providing flanges 8 at both ends of the composite rod 4, multiple support rods 7 can be spliced ​​and disassembled into several short sections, significantly reducing the volume of a single composite rod 4 during transportation and handling, improving the convenience of transportation and loading / unloading, and facilitating rapid on-site assembly and splicing, thus reducing construction difficulty and cost. The support rods 7 need to be inserted 0.5-1m into the ground. The angle between the support rod 7 and the ground is 60°. The end of the composite rod 4 near the steel pipe 2 does not have a flange structure.

[0031] In this embodiment, a ramp 9 is provided between each of the two adjacent flanges 8, and the opening of the two ramps 9 together forms a triangular structure. By setting the ramp 9 between the adjacent flanges 8 to form a triangular structure, even if the support rod 7 cannot be disassembled smoothly due to bolt aging or corrosion during maintenance, a cutting machine can be used to cut along the opening of the triangular structure, thereby achieving precise guidance, ensuring that the cutting operation is simple and safe, and avoiding damage to the surrounding structure.

[0032] In this embodiment, the connector includes two second arc-shaped plates 10 located on the surface of the steel pipe 2. Connecting plates 11 are fixed to both sides of each second arc-shaped plate 10. The connecting plates 11 have slots on opposite sides, and adjacent slots are fixed to the surface of the steel pipe 2 by bolts. This structure allows for adjustment of the bolt tightness during installation, ensuring the connector is tightly fixed to the surface of the steel pipe 2. It also allows for limited fine-tuning to accommodate construction errors, achieving a stable connection between the combined pole 4 and the steel pipe 2, thus improving the reliability and ease of construction of the overall tower structure.

[0033] In this embodiment, the connecting foundation 5 includes a vertical cylinder 12. A sliding rod 13 is elastically connected inside the vertical cylinder 12. Several slots are formed on the circumference of the inner wall of the sliding rod 13, and ball-head rods 14 are elastically connected inside these slots. Several slots 15, adapted to the ball-head rods 14, are formed through the circumference of the vertical cylinder 12. The upper end of the vertical cylinder 12 and the bottommost support rod 7 are fixed together with bolts. By providing ball-head rods 14 on the sliding rod 13, when the sliding rod 13 is inserted into the vertical cylinder 12, the ball-head rods 14 can pop out and contact the inner wall of the vertical cylinder 12 or the ground, thereby significantly enhancing the grip after the connecting foundation 5 is pre-embedded in the ground and improving the stability of the tower. The connection between the vertical cylinder 12 and the support rod 7 also utilizes the flange structure of the combined rod 4.

[0034] In this embodiment, the internal space of the vertical cylinder 12 is a T-shaped groove structure, and the sliding rod 13 is a T-shaped rod structure. A gap is left between every two adjacent slots 15. When the sliding rod 13 is in the unretracted state, the end of the ball head rod 14 fits into this gap, thereby preventing the ball head rod 14 from protruding. Through this structural design, the ball head rod 14 can be prevented from protruding during the transportation and handling of the connecting foundation 5, ensuring safe and convenient transportation. After the sliding rod 13 is inserted into the ground, the ball head rod 14 can pop out to provide positioning and gripping force, ensuring the stability of the tower foundation installation.
