Description

Technical Field

[0001] This utility model relates to the field of concrete pole technology, specifically to concrete poles with self-reinforcing ribs. Background Technology

[0002] Concrete poles are precast concrete components manufactured using a centrifugal casting process. Their core structure is a composite of high-strength steel reinforcement and concrete, utilizing the synergistic effect of the tensile strength of the steel and the compressive strength of the concrete to form a hollow column with a tapered or uniform diameter. They are primarily used in power transmission lines, lighting systems, and communication networks to support overhead conductors, possessing key advantages such as bending resistance, crack resistance, corrosion resistance, and long service life.

[0003] Chinese utility model patent CN214942949U discloses a ring-shaped concrete pole, which includes "a pole body structure, the pole body structure including a first steel ring structure and a second steel ring structure, a plurality of equally spaced first reinforcing ribs are arranged in the hollow position between the first steel ring structure and the second steel ring structure, and second reinforcing ribs are arranged on both sides of the first reinforcing ribs structure. A steel cage structure is connected to the outside of the first steel ring structure by welding, and the steel cage structure and the first steel ring structure"; however, this design is a traditional steel cage design, with the second steel ring structure only designed in the middle, that is, a ring of stirrups is welded inside the main reinforcement. However, the pole body is generally large, and the stress distribution in various parts is not uniform. This design cannot form a solid spatial structure, and the strength improvement is limited. Utility Model Content

[0004] The purpose of this invention is to provide a concrete pole with a self-reinforcing rib structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete pole with a self-reinforcing rib structure, comprising a concrete frame, wherein a steel reinforcement frame is provided inside the concrete frame, and the concrete frame and the steel reinforcement frame are integrally cast; the concrete frame includes the pole body; the steel reinforcement frame includes several longitudinal main bars, and several stirrups are welded to the outside of the longitudinal main bars, the longitudinal main bars and the stirrups form a steel cage structure, the stirrups are provided with a dense zone and a non-dense zone, and several diagonally cross reinforcing ribs are welded to the middle of the dense zone of the stirrups.

[0006] The beneficial effects of this utility model are as follows: by setting up a reinforced zone and a non-reinforced zone outside the steel cage, the weaker parts of the pole are reinforced in a focused manner. Then, by welding several diagonal cross reinforcing bars in the reinforced zone, the diagonal cross reinforcing bars and the stirrups in the reinforced zone form a spatial truss, which improves the shear resistance and compressive strength of the concrete, and ultimately improves the strength and service life of the entire device.

[0007] To enhance the stability of the device:

[0008] A further configuration is provided: a pole base is fixedly installed at the lower end of the pole body.

[0009] By adopting the above technical solution, the bottom of the device is generally buried deep in the soil. By designing the pole base, the contact area between the device and the bottom is increased, thereby improving the stability of the bottom of the pole.

[0010] To facilitate installation and maintenance:

[0011] The pole body is further configured such that its outer surface is provided with several arc-shaped grooves.

[0012] By adopting the above technical solution and setting the arc-shaped groove, users can use the arc-shaped groove for leverage when climbing the top of the pole for future maintenance, making it easier for users to maintain the pole.

[0013] To induce pedestrians to accidentally collide with utility poles:

[0014] The pole body is further configured such that several luminous warning rings are symmetrically installed on its outer surface, and the arc-shaped grooves are distributed intersectingly with the luminous warning rings.

[0015] By adopting the above technical solution, the utility poles are generally installed outdoors. When visibility is low at night, the poles can be prevented from being hit by luminous warning rings.

[0016] To improve the strength of the non-reinforced zone of the steel cage:

[0017] Further configuration: a spiral reinforcing bar is welded to the middle of the non-reinforced zone of the stirrup, and the lower end of each longitudinal main bar is provided with a bent reinforcing bar anchored into the interior of the pole base.

[0018] By adopting the above technical solution, spiral reinforcing bars are set in the non-reinforced area, which can cooperate with the external stirrups to firmly support the longitudinal main bars in the middle, forming a spatial structure and improving the shear strength of the concrete pole. At the same time, the elbow steel bars are set and anchored into the inside of the pole base, which also improves the strength of the pole base.

Several stirrups 22 are welded to the outside of the longitudinal main bars 21. The longitudinal main bars 21 and the stirrups 22 form a steel cage structure. The stirrups 22 are divided into dense and non-dense zones. Several diagonal cross reinforcing ribs 23 are welded to the middle of the dense zone of the stirrups 22.

[0026] In this embodiment, as Figure 1 and Figure 2 As shown, a pole base 12 is fixedly installed at the lower end of the pole body 11.

[0027] In this embodiment, as Figure 1 and Figure 2 As shown, the outer surface of the pole body 11 is formed with several arc-shaped grooves 13.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a spiral reinforcing bar 24 is welded in the middle of the non-reinforced area of ​​the stirrup 22, and the lower end of the longitudinal main bar 21 is provided with a bent reinforcing bar 25 anchored into the inside of the pole base 12.

[0030] The working process of this concrete utility pole with its own reinforcing ribs is as follows:

[0031] First, the maker welds several stirrups 22 to the outer surface of all longitudinal main bars 21 to form a steel cage. Then, spiral reinforcing bars 24 are placed in the middle of the steel cage and welded to improve the compressive strength of the concrete in the non-reinforced zone. Next, diagonal cross reinforcing bars 23 corresponding to the number of stirrups 22 are welded to the reinforced zones on both sides to form a spatial truss and improve the shear resistance of the device. Finally, bent reinforcing bars 25 are welded to the bottom of the longitudinal main bars 21 to strengthen the strength and shear resistance of the pole base 12. Then, the steel cage is erected and concrete is poured to form a single piece. After the concrete has solidified, a luminous warning ring 14 is installed on the outer surface of the pole.
