Embodiment 1

[0024] A kind of processing method of reinforced composite material pole tower of the present invention, comprises the following steps:

[0025] Step 1, weigh PVC SG5, organotin stabilizer, dioctyl phthalate, calcium stearate, polyethylene wax, microcrystalline wax, calcium carbonate, barium sulfate, paraffin wax, processing modifier, impact resistance Modifier and carbon black, after stirring and mixing the weighed raw materials, add them to the injection molding machine, and use the injection mold to process them into a tubular structure with several vertical notches and tapers;

[0026] Step 2, place the supporting steel bars one by one into the vertical notches, and then fill the gaps with glue,

[0027] Step 3, evenly wrap the square cloth in the tubular structure to form a wrapping layer;

[0028] Step 4: Spread the reinforcing glue evenly on the outside of the wrapping layer, and then place it in an environment of 50°C to 60°C to dry for 30 to 60 minutes to form a rein...

Embodiment 2

[0032] As shown in the figure, a reinforced composite material tower according to the present invention includes a bottom with a larger outer diameter and a top with a smaller outer diameter. The bottom and the top form a tower with a taper, and the middle of the reinforced composite material tower It is a main support pipe 1 with a taper, and several vertical notches 2 are evenly distributed on the outer surface of the main support pipe, and support steel bars 3 are placed in the vertical notches, and the vertical notches are also filled with fixed Glue, the outer surface of the vertical notch filled with fixed glue forms a complete circle with the outer surface of the main support tube, and the outer surface of the main support tube is wrapped with a wrapping layer 4 made of square cloth, and the outer surface of the wrapping layer is evenly applied There is a reinforced glue layer 5, and a first outer sheath layer 6 and a second outer sheath layer 7 are provided in sequence ...

Embodiment 3

[0038] The material of the main support tube in the present invention is made of the following raw materials in parts by weight: 1000 parts of PVC SG5, 1 to 4 parts of organotin stabilizer, 20 to 30 parts of dioctyl phthalate, 5 to 8 parts of calcium stearate 3-6 parts of polyethylene wax, 6-10 parts of microcrystalline wax, 100-120 parts of calcium carbonate, 10 parts of barium sulfate, 8-10 parts of paraffin wax, 4-8 parts of processing modifier, 15 parts of impact modifier ~20 parts, 0.5 parts of carbon black.

Abstract

The invention belongs to the technical field of electric power poles and towers, and particularly relates to a method for processing a steel bar-reinforced composite pole and tower. The method comprises the following steps: step one, injection-molding a tubular structure; step two, placing steel bars and fixing; step three, processing a first wrapping layer; step four, processing a reinforcing glue layer; step five, processing a first outer sheath layer; and step six, processing a second outer sheath layer. The method provided by the invention overcomes deficiencies of the prior art; a core supporting mechanism is composed by a main supporting tube and a plurality of vertical steel bars surrounding an outer surface of the main supporting tube in the middle; the steel bars provide supporting capacity required by the pole and tower; the main supporting tube assists the steel bars to play roles of resisting corrosion and rust and reinforcing the steel bars; the first wrapping layer, the reinforcing glue layer, the first sheath layer and the second sheath layer are sequentially arranged on the outer surface of the main supporting tube to further strengthen the anti-corrosion and anti-oxidation capability of the pole and tower, and improve the service life of the pole and tower.

Description

technical field [0001] The invention belongs to the technical field of power poles and towers, and in particular relates to a processing method for steel bar type composite material poles and towers. Background technique [0002] Transmission line tower structure is a special support structure in power overhead line facilities, and its structural performance directly affects the safety, economy and operational reliability of the line. With the development of my country's power grid, transmission line engineering presents a trend of long-distance, large-scale and large-scale development. At present, transmission line towers are generally composed of steel and concrete. In particular, the use of a large number of steel structure poles and towers has increased the demand for steel products year by year, consuming a large amount of mineral resources and causing pollution to the ecological environment. At the same time, a large number of steel materials are used as iron tower m...
