A manufacturing process of prefabricated cement utility poles

Abstract

The invention discloses a manufacturing process of prefabricated cement utility poles, which relates to the technical field of electric power construction equipment, and includes the following steps: S1, material preparation, selecting two kinds of straight rod-shaped steel bars with different lengths as the reinforcement skeleton material for making cement utility poles , the long straight rod-shaped steel bars are used as the main reinforcement, and the short straight rod-shaped steel bars are used as the stirrups; S3, skeleton welding, weld and fix the main reinforcements surrounded by a circle at equal intervals in step S2, and weld the stirrup perpendicular to the reinforcement between two adjacent reinforcements, so that two adjacent reinforcements The position between the root main bars is fixed. The invention controls the position of the main bars installed in the fixing holes of the steel bars through the axial movement of the bolts, and independently adjusts the position of each main bar that forms a circle at equal intervals on the circumference, so as to facilitate the control of the diameter of the steel bar skeletons that form a circle.

Description

technical field [0001] The invention relates to the technical field of electric power construction equipment, in particular to a manufacturing process of prefabricated cement utility poles. Background technique [0002] Telephone poles, as the name implies, are poles for wires. They appear in various villages, fields, roads, and streets. They are one of the important infrastructures in early China. All kinds of telegraph poles in the early days started from wooden poles, even including voltage levels. Later, due to the development of steel and reinforced concrete and technical requirements, these two materials replaced most of the wooden poles for the high-voltage power line poles that were too high, and the applicable wood was gradually scarce, and it was basically difficult to see wooden poles in the city. [0003] Existing utility poles are formed by pouring steel bars and concrete. A plurality of steel bars are welded into a steel bar frame, and the steel bar frame and c...

Problems solved by technology

[0007] In view of the problems in the prior art, the purpose of the present invention is to provide a prefabricated cement utility pole manufacturing process, which solves the problem of clamping and fixing each main reinforcement in the process of fixing the main reinforcement of the steel skeleton, which makes the fixing operation of the main reinforcement cumbersome. , and it is difficult to control the technical problem that the main ribs are surrounded by a circle at equal intervals on the circumference
