Description

Technical Field

[0001] This utility model relates to the field of power engineering poles and towers, and in particular to a novel 110kV prefabricated concrete composite pole. Background Technology

[0008] A novel 110kV precast concrete composite pole comprises several precast concrete pole bodies assembled sequentially from top to bottom. Each precast concrete pole body is equipped with an embedded ground plate. Adjacent precast concrete pole bodies are fixed together by connecting flanges. Steel pipe crossarms are symmetrically arranged on each precast concrete pole body. The steel pipe crossarms are connected to the precast concrete pole bodies via crossarm flanges. The connecting flanges and the crossarm flanges are embedded in the precast concrete pole bodies. Several stiffening plates are provided on the connecting flanges.

[0009] According to one aspect of this utility model, the spacing between any longitudinally adjacent steel pipe crossarms is equal.

[0018] The advantages of this utility model are as follows: by pre-embedding the connecting flange and crossarm flange into the precast concrete pole body, the overall structure has greater rigidity, which has obvious advantages in high shear wind speed areas and low wind speed scenarios, and can effectively reduce the operating amplitude of the tower throughout its entire life cycle; lower operation and maintenance costs, stronger corrosion resistance, higher production efficiency, segmented transportation, convenient splicing, and rapid hoisting; and a significant reduction in the amount of steel used.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 3As shown, a novel 110kV prefabricated concrete composite pole includes several prefabricated concrete pole bodies 4 assembled sequentially from top to bottom. Each prefabricated concrete pole body 4 has an embedded grounding plate 3. Adjacent prefabricated concrete pole bodies 4 are fixed together by connecting flanges 1. Steel pipe crossarms 6 are symmetrically arranged on each prefabricated concrete pole body 4. The steel pipe crossarms 6 are connected to the prefabricated concrete pole bodies 4 via crossarm flanges. The connecting flanges 1 and the crossarm flanges are embedded in the prefabricated concrete pole bodies 4. Several stiffening plates 2 are provided on the connecting flanges 1. In use, the prefabricated concrete pole bodies 4 are prefabricated in sections using tubular prefabricated concrete. The connecting flanges 1 and crossarm flanges are embedded in the prefabricated concrete pole bodies 4. After each pole body section is hoisted and assembled, the steel pipe crossarms 6 are assembled with the pre-embedded flanges on the pole body to form a 110kV prefabricated concrete composite pole.

[0026] The 110kV precast concrete composite poles in this solution have greater overall structural rigidity, offering significant advantages in high-shear-speed areas and low-wind-speed scenarios, effectively reducing the operational amplitude of the towers throughout their lifespan. They also offer advantages such as lower maintenance costs, stronger corrosion resistance, higher production efficiency, segmented transportation, convenient assembly, and rapid hoisting. Furthermore, they significantly reduce the amount of steel used.

[0027] In this embodiment, the precast concrete pole body 4 is tubular.

[0028] In practical applications, the spacing between any two longitudinally adjacent steel pipe crossarms 6 is equal. This equal spacing ensures that the conductor load and wind load, among other external forces, are borne relatively evenly by each crossarm.

[0029] In this embodiment, there are eight steel pipe crossarms 6, symmetrically arranged on both sides of the precast concrete pole body 4. This ensures uniform stress distribution and improves the overall structural stability.

[0030] In this embodiment, the pre-embedded ground plate 3 is pre-embedded at both ends of the precast concrete pole body 4 at a distance of one meter from the ground, and the quantity is 2.

[0031] In this embodiment, the embedded part ground plate 3 is a perforated steel plate.

[0032] In practical applications, the length of the precast concrete pole body 4 is 2 to 5 meters.

[0033] In practical applications, the stiffening plate 2 is prefabricated together with the connecting flange 1 and welded onto the connecting flange 1.

[0034] In practical applications, the wall thickness of the precast concrete pole body 4 is 200-400mm.

[0035] In practical applications, the concrete grade of the precast concrete pole body 4 is C40.

[0036] In practical applications, the precast concrete pole body 4 is provided with mounting holes.

[0037] In practical applications, the mounting hole is equipped with a pre-embedded ladder 5. The mounting hole facilitates the installation of the pre-embedded ladder 5.

[0038] In practical applications, the connecting flange 1 is provided with several connecting holes 7.

[0039] In practical applications, the angle between the stiffening plate 2 and the connecting hole 7 relative to the central axis of the connecting flange 1 is 8°.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
