Description

Technical Field

[0001] This utility model relates to the field of reinforced concrete pole technology, and in particular to a high crack-resistant ring-shaped reinforced concrete pole. Background Technology

[0002] The power industry is a core foundational industry that ensures the stable operation of the national economy and the electricity consumption for urban and rural production and daily life. As a key channel for the transmission of power energy, the safe and reliable operation of transmission lines depends on the stability of various supporting components. Circular reinforced concrete poles, with their advantages of controllable cost, good structural stability, and strong resistance to natural corrosion, have become the core infrastructure supporting conductors, insulators, and auxiliary equipment in transmission lines at all levels.

[0003] Traditional reinforced concrete poles have the following shortcomings: First, the internal steel reinforcement cage is mostly a simple structure with unidirectional longitudinal arrangement and sparse transverse stirrups. When the pole is subjected to lateral wind force or uneven load, stress tends to concentrate in the core of the pole, the weakest section in the middle, and the connection between the root and the foundation, resulting in micro-cracks on the concrete surface. After long-term use, the cracks will gradually expand, reducing the load-bearing capacity of the pole. Second, the connection between the pole and the foundation relies only on the simple cooperation between a single-layer anchor plate and the foundation. The interlocking area between the embedded components and the concrete foundation is limited, resulting in uneven load transfer and the formation of stress concentration points at the root, which can lead to root cracking.

[0004] To address the problems of stress concentration and cracking in existing ring-shaped reinforced concrete poles, poor root reinforcement, and insufficient core crack resistance, a ring-shaped reinforced concrete pole that solves these problems is needed. Utility Model Content

The lower end of the pole body 1... A reinforcing member 4 is fixedly connected to the upper side of the second anchoring plate 7 on the outer side. The lower side of the reinforcing member 4 is fixedly connected to the upper side of the first embedded ring 8. An outer spiral steel rib 5 is provided on the outer side of the mandrel 2, and an inner spiral steel rib 6 is provided on the inner side of the mandrel 2. Both the outer spiral steel rib 5 and the inner spiral steel rib 6 are made of bidirectional spiral weaving. The outer spiral steel rib 5 is fixedly connected to the outer side of the mandrel 2 by stainless steel wire, and the inner spiral steel rib 6 is fixedly connected to the inner side of the mandrel 2 by stainless steel wire. Both the outer spiral steel rib 5 and the inner spiral steel rib 6 are fixedly connected to the inside of the rod body 1.

[0032] The mandrel 2 is fixedly connected to the first anchor plate 3 and the second anchor plate 7. The mandrel 2 is made of low alloy high-strength steel. The first anchor plate 3 and the second anchor plate 7 limit the position of the mandrel 2 inside the rod body 1 to prevent the mandrel 2 from shifting and causing stress imbalance. Then, the outer spiral steel rib 5 and the inner spiral steel rib 6 are installed on the inner and outer sides of the mandrel 2 by stainless steel wire. The outer spiral steel rib 5 and the inner spiral steel rib 6 are made of stainless steel. After the stainless steel is poured, the rod body 1 is formed. When the rod body 1 is stressed by external force, the outer spiral steel rib 5 and the inner spiral steel rib 6 can disperse the stress generated by the external force in all directions, avoid local stress concentration and cracks, and prevent cracks from appearing.

The first reinforcing rib 12 and the second reinforcing rib 14 are hot-rolled ribbed steel bars. The second anchor plate 7, the first embedded ring 8, the second embedded ring 10, the third embedded ring 11 and the fourth embedded ring 17 are connected in series to form a multi-layer stress frame to prevent stress concentration from causing cracks at the root of the rod 1.

Then, the outer spiral steel rib 5 and the inner spiral steel rib 6 are installed on the inner and outer sides of the mandrel 2 by stainless steel wire. After stainless steel is poured in, the rod body 1 is formed. When the rod body 1 is stressed by external force, the outer spiral steel rib 5 and the inner spiral steel rib 6 will disperse the stress and prevent cracks. The first embedded ring 8 is fixedly connected to the outside of the second anchoring plate 7. Then, the second embedded ring 10, the third embedded ring 11 and the fourth embedded ring 17 are fixedly installed on the outside of the connecting rod 9. Finally, the first embedded ring... 8. The second embedded ring 10, the third embedded ring 11 and the fourth embedded ring 17 are inserted into the embedded point. The first reinforcing rib 12 and the second reinforcing rib 14 and the hook 13 fixedly connected to their outer ends are embedded in the surrounding concrete to further strengthen the bottom strength of the rod body 1. The second anchoring plate 7, the first embedded ring 8, the second embedded ring 10, the third embedded ring 11 and the fourth embedded ring 17 are connected in series to form a multi-layer stress frame to prevent stress concentration from causing cracks at the root of the rod body 1. The umbrella-shaped plate 15 and the annular groove 16 can increase the contact area between the bottom and the concrete to ensure that the load is evenly transferred to the foundation.
