Concrete pole outer surface mark forming method

[0028] Please refer to figure 1 Shown, embodiment one of the present invention is:

[0029] A marking forming method on the outer surface of a cement pole, which comprises making a mold piece 2 with the same shape as the marking; attaching the mold piece 2 to the inner wall of a mold 1, the mold 1 includes an inner mold 4, and the inner mold 4 is arranged on the mold 1. Cavity; install steel bar 5 in mold 1, and evenly position steel bar 5 along the circumference, close mold 1, pour cement in mold 1, open the mold after the cement hardens, and take out cement rod 3.

[0030] To sum up, the method for forming markings on the outer surface of cement rods provided by the present invention only needs to make molds with uniform specifications, and attach the markings to be processed on the inner wall of the mold in the form of dies, and then process the markings with grooves. The production cost is low, the versatility is good, the processing cycle is short, and the industrial competitiveness is strong. The material of the mold is rubber, which makes the mold have certain elasticity and structural strength. It is miscible with cement, allowing a small amount of cement to penetrate between the die and the inner wall of the mold. When demolding, the die can be kept on the side of the cement rod, which simplifies the cleaning steps of the mold. When the mold is assembled, the inner mold can be set to produce The hollow cement pipe is produced to reduce the weight of the cement pipe and save raw materials. The steel bar has the characteristics of high strength and tensile resistance. Adding it to the cement pipe can greatly increase the strength of the cement pipe.
