The utility model has the advantages of the dead weight is light, crack resistance durability is good, is applicable to the power transmission pole in the mountain area that big load line engineering, corrosion resistant area and transportation condition are not convenient.
Description
Technical Field
The utility model belongs to combined material pole field especially relates to a compound pole of centrifugation steel fibre concrete glass fiber.
Background
With the continuous and rapid development of economy in China, the power industry in China is continuously developed, and meanwhile, the development of urban and rural industrial and agricultural industry and agriculture puts strict requirements on the development of power transmission and distribution lines in a power system. The twelve-five planning target in China is that the 110kV and above lines in China reach 133 ten thousand meters, the planning target in 2020 is that the 110kV and above lines in China reach 176 ten thousand meters, and dozens of large transmission line engineering construction is carried out in 2025 years of electric power planning in China. The durability of the transmission pole plays an even more important role in the safety and transmission of the power line.
The concrete pole is widely applied to the fields of power transmission and transformation engineering, railway electrification engineering and communication due to the advantages of convenient operation and maintenance, steel saving and the like, and is particularly widely applied to areas with good plains and transportation conditions in China. The total electric pole production of the electric pole enterprises in the whole country in the last half of 2017 is 823 ten thousand, the synchronous increase is 17.2% compared with 2016, and the concrete electric pole has a very wide market space.
However, although the common concrete pole has the advantages, the common concrete pole also has the defects of heavy weight, easy cracking, poor durability and the like, and has potential safety hazards in the operation of a power grid. With the continuous development of urbanization, the defects of the traditional electric pole are gradually highlighted. In addition, the advantage of current glass fiber composite pole can effectively reduce the pole dead weight, and inside concrete can effectively be protected to outside glass fiber, and the shortcoming is that inside concrete crack resistance is poor and tensile strength is lower, easily ftractures, and the durability still is relatively poor under adverse circumstances.
SUMMERY OF THE UTILITY MODEL
In order to overcome the current not enough about current compound pole performance, especially centrifugal concrete glass fiber composite pole performance not enough, the utility model aims at providing a centrifugal steel fiber concrete glass fiber composite pole, this kind of pole has advantages such as the dead weight is light, crack resistance durability is good.
The utility model provides a compound pole of centrifugation steel fibre concrete glass fibre, pole are cylindrical or conical hollow structure, are the hollow structure of layer, compound glass fibre layer, steel fibre concrete layer and center of waiting from outer to interior in proper order, and the upper end on compound glass fibre layer is equipped with the upper cover plate, and the lower extreme is equipped with down the apron, and the upper cover plate, lower apron form seal structure with compound glass fibre layer together, and the parcel is outside at steel fibre concrete layer.
The steel fiber concrete layer is formed by centrifuging steel fiber concrete, the content of the steel fiber is 0.3-0.6% of the volume of the concrete, the concrete is fine aggregate concrete, and the maximum diameter of the aggregate is not more than 20mm, so that the requirements of crack resistance, durability and a centrifuging process are met.
The composite glass fiber layer is a composite layer of glass fiber and resin.
The weather-resistant layer is a weather-resistant coating or a composite layer of the weather-resistant coating and glass fiber.
The upper cover plate and the lower cover plate are both composite layers of glass fiber and resin
The utility model has the advantages that: the self-weight is light, the crack resistance and the durability are good, and the device is suitable for power transmission poles in heavy-load line engineering, corrosion-resistant areas and mountainous areas with inconvenient transportation conditions.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, a compound pole of centrifugation steel fiber concrete glass fiber, the pole is cylindrical or conical hollow structure, from outer to interior be resistant time layer 5 in proper order, compound glass fiber layer 1, the hollow structure at steel fiber concrete layer 2 and center, the upper end on compound glass fiber layer 1 is equipped with upper cover plate 3, the lower extreme is equipped with down apron 4, upper cover plate 3, apron 4 forms seal structure with compound glass fiber layer 1 down together down, the parcel is outside at steel fiber concrete layer 2, thereby protection steel fiber concrete layer 2.
The steel fiber concrete layer 2 is formed by centrifuging steel fiber concrete, the content of the steel fiber is 0.3-0.6% of the volume of the concrete, the concrete is fine aggregate concrete, and the maximum diameter of the aggregate is not more than 20mm, so that the requirements of crack resistance, durability and a centrifuging process are met.
The composite glass fiber layer 1 is a composite layer of glass fiber and resin.
The weather-resistant layer 5 is a weather-resistant coating or a composite layer of the weather-resistant coating and glass fiber.
Preferably, the upper cover plate 3 and the lower cover plate 4 are both composite layers of glass fiber and resin.
In the above scheme, compound glass fiber layer 1 has better tensile strength, can effectively reduce concrete cross sectional area demand, and then reduces the pole dead weight. In addition, because ordinary concrete crack resistance is relatively poor, the utility model discloses use steel fiber concrete centrifugal forming steel fiber concrete layer 2, can improve the crack resistance and the durability of inside concrete, satisfy the performance requirement of the transmission pole in corrosion-resistant area. The utility model discloses in, the organic combination of material and structure has brought good performance.
