Embodiment 1

[0071] Such as Figure 1-12 and Figure 25 As shown, a production process of a high-strength built-in post-tensioned reinforced concrete pole is used to produce a whole single pole, the single pole is ∮190mm×15m, and the taper of the pole body 32 is 1:75, including the following steps:

[0072] 1.1. Evenly weld 8 main ribs 6 on the inner side of the steel ring 5 at the tip of the pole. The main ribs 6 are HRB500 ordinary steel bars with a size of ∮16mm×14.8m. When welding, the main ribs 6 and the steel ring 5 end faces There is enough thickness for the backing plate to be embedded in the tension end composite anchor 2, and the tension end composite anchor 2 is arranged at one end of the main reinforcement 6.

[0073] 1.2. Arrange the stand rings evenly in the main ribs 6 at intervals of 1000mm along the axial direction. The stand rings are welded together by the outer frame stand ring 10 and the inner frame stand ring 34 through the equally divided connecting steel bars 35 to...

Embodiment 2

[0094] Embodiment 2: as Figure 13-23 As described above, a production process for high-strength built-in post-tensioned reinforced concrete poles is used to produce segmented poles, specifically for the production of ∮230mm×18m segmented poles, which consist of 9m upper section poles and 9m The lower pole is composed. The upper section is ∮230mm×9m, the lower section is ∮350mm×9m, and the taper of the pole body 32 of the two poles is 1:75, including the following steps:

[0095] 2.1. Evenly weld 10 main ribs 6 on the inside of the steel ring 5 at the tip of the pole. The main ribs 6 are HRB500 ordinary steel bars with a size of ∮16mm×8.8m. When welding, the main ribs 6 and the steel ring 5 at the tip Between the end faces, the thickness of the backing plate embedded in the tension end combination anchor 2 is reserved, and the tension end combination anchor 2 is arranged on one end of the main reinforcement 6; for the upper section of the pole, the root of the pole is also we...

Embodiment 3

[0108] Embodiment 3: as Figure 22-24 As described above, a production process for high-strength built-in post-tensioned reinforced concrete poles is used to produce segmented poles, specifically for the production of ∮230mm×27m segmented poles, consisting of a 9m upper segment pole, a 9m The middle pole and the 9m lower pole are composed. The upper section is ∮230mm×9m, the middle section is ∮350mm×9m, and the lower section is ∮350mm×9m. The taper of the pole body 32 of the three poles is 1:75, including the following steps:

[0109] 3.1. Evenly weld 16 main ribs 6 on the inner side of the steel ring 5 at the tip of the pole. The main ribs 6 are HRB500 ordinary steel bars with a size of ∮16mm×8.8m. When welding, the main ribs 6 and the steel ring 5 at the tip Between the end faces, there is a thickness of the backing plate embedded in the tension end combination anchor 2, and the tension end combination anchor 2 is arranged at one end of the main rib 6; for the upper pole an...

Abstract

The invention discloses a high-strength built-in post-tensioning reinforced concrete electric pole and a production process thereof. The production process comprises the following steps that a plurality of main reinforcements are evenly welded to the inner side of a steel plate ring at the tip of the electric pole, an erecting ring is fixedly arranged on the inner sides of the main reinforcements in the axial direction, and the main reinforcements and short reinforcements penetrate through a limiting disc to be limited. And a plurality of prestressed steel strands penetrate into the steel plate ring, the outer side of a preliminarily-manufactured reinforcement cage is sleeved with a protection shell to protect supporting points, the prestressed steel strands are arranged in place, one end of each prestressed steel strand is tensioned twice, and the two ends of each prestressed steel strand are filled and sealed. The post-tensioning reinforced concrete electric pole manufactured through the method can fully play a tensioning role.

Description

technical field [0001] The invention relates to a production process of concrete electric poles and the electric poles obtained by using the process, especially a production process of high-strength built-in post-tensioned reinforced concrete electric poles and the electric poles produced by the process. in transmission and distribution lines. Background technique [0002] Reinforced concrete poles are used in the structure of substations and the supporting function of transmission and distribution lines. According to their uses, they are divided into straight poles, branch poles, corner poles, tension poles and terminal poles. There are still a lot of applications in the line. Especially in the third- and fourth-tier cities and villages, the distribution lines are still mainly overhead. The overhead distribution lines are scattered all over the country and have a wide radiation range. Compared with cable lines, they are more economical. The main supporting role of overhead...
