Description

Technical Field

[0001] The utility model belongs to the technical field of concrete poles, in particular to a ring-shaped concrete pole connecting flange reinforcement and anti-corrosion structure. Background Art

[0002] Annular concrete poles are composed of sand, stone, cement, steel and admixtures. They are formed by high-speed centrifugation and have the advantages of strong bearing capacity, low cost, smooth and beautiful appearance, long service life and no maintenance. They are mainly used for overhead power lines and line facilities such as communications and railways. Annular concrete (assembled) poles: If higher and longer annular concrete poles are required in line construction, but the poles are too long and cannot be transported due to the impact of roads, the poles need to be produced and processed in sections to solve the transportation problem, and then assembled after being transported to the site for line construction. In order to ensure the safety of line operation, according to national and industry standards, the connectors (flanges) of assembled poles must be effectively treated with anti-corrosion. The more common anti-corrosion method is to use hot-dip galvanizing for the pole connection flanges and accessories.

[0003] For example, a concrete pole with announcement number CN207377240U includes a hollow pole body, the pole body includes a steel skeleton and a concrete protective layer cast with concrete mortar and wrapping the steel skeleton, the steel skeleton also includes an anti-corrosion coating covering the surface, and the steel skeleton is made of steel bars of two different diameters, one large and one small, bundled or welded in a staggered manner. On the one hand, it can avoid the existing steel skeleton being prepared with steel bars of the same size. Due to the requirements of technical parameters, in order to ensure the physical parameter performance of the pole, it is necessary to use large-size steel bars as much as possible, which not only causes waste of metal materials, but also inevitably increases the cost of concrete poles, which is not conducive to the promotion and application of concrete poles;

[0004] The main steel bars (ordinary threaded steel bars) of this concrete pole are connected to the connecting flange as a whole by electric welding. However, during the electric welding process, the flange and the main steel bars (threaded steel bars) inside the pole have a high temperature of about 7000 degrees. The thermal effect of the electric arc will destroy the zinc layer of the hot-dip galvanized flange, affecting the anti-corrosion effect of the flange, thereby affecting the durability of the pole flange and the safety of line operation. In order to solve the above problems, a circular concrete pole connecting flange reinforcement and anti-corrosion structure is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a ring-shaped concrete pole connection flange reinforcement and anti-corrosion structure to solve the above problems, including:

[0006] The concrete pole body also includes a steel cage, wherein the steel cage is composed of a plurality of main bars and longitudinal bars arranged in a circle, a plurality of annular bars are tied to the outer walls of the main bars and longitudinal bars, and a casting layer is cast on the outer wall of the steel cage;

[0007] The connecting flange is fixedly installed on the upper and lower sides of the concrete pole body. A reinforcement ring is welded on the inner wall of the connecting flange. A plurality of main reinforcement connection holes and longitudinal reinforcement connection holes are opened on the upper surface of the reinforcement ring.

[0008] Through the above technical scheme, when the concrete pole body is connected to the connecting flange, the main reinforcement and the longitudinal reinforcement are first inserted into the main reinforcement connection hole and the longitudinal reinforcement connection hole in the hanging reinforcement ring respectively and fixed, and then the concrete is poured for high-speed centrifugal molding. After molding, the anchoring reinforcement bolts and the main steel bars are all wrapped in concrete, which can better play an anti-corrosion role. The original electric welding method is replaced by the anchoring method to connect the flange, which can prevent the coating of the outer wall of the flange from being damaged.

[0009] In a preferred embodiment, the length of the main ribs is 50 mm longer than that of the longitudinal ribs.

[0010] In a preferred embodiment, a plurality of external reinforcing ribs are welded to the outer wall of the connecting flange.

[0011] Through the above technical solution, the mechanical strength of the connecting flange is improved by providing external reinforcing ribs.

[0013] Through the above technical solution, the mechanical strength between the connecting flange and the rib-hanging pipe is improved by providing the internal reinforcing ribs.

[0014] In a preferred embodiment, the main rib connection holes and the longitudinal rib connection holes are arranged in pairs.

[0015] In a preferred embodiment, a tapping portion is provided at the lower end of the main rib, and a nut is threadedly connected to the outer wall of the tapping portion.

[0016] Through the above technical solution, anchoring is performed by reinforcing the main reinforcement with nuts.

[0017] In a preferred embodiment, the main reinforcement, the longitudinal reinforcement and the annular reinforcement are tied together by steel wires.

[0021] When the concrete pole body is connected to the connecting flange, first insert the main reinforcement and longitudinal reinforcement into the main reinforcement connection hole and the longitudinal reinforcement connection hole in the hanging reinforcement ring respectively and fix them, and then pour the concrete for high-speed centrifugal forming. After forming, the anchoring reinforcement bolts and the main steel bars are all wrapped in concrete, which can better play an anti-corrosion role. The original electric welding method is replaced by the anchoring method to connect the flange, which can prevent the coating on the outer wall of the flange from being damaged.
