Small-bending-moment steel bar concrete pole as well as production device and manufacturing process thereof

Abstract

The invention provides a small-bending-moment steel bar concrete pole as well as a production device and a manufacturing process thereof. The small-bending-moment steel bar concrete pole comprises a steel bar framework and a concrete layer; the concrete layer wraps the steel bar framework; the steel bar framework comprises multiple main ribs and multiple auxiliary ribs; the main ribs and the auxiliary ribs are steel bars for prestressed concrete; the multiple main ribs are axially and annularly arranged in the small-bending-moment steel bar concrete pole; the auxiliary ribs are symmetrically bound to the main ribs. The small-bending-moment steel bar concrete pole provided by the invention is widely applied to all 10kV integral electric pole types on state grid lines; the steel bars for prestressed concrete are adopted for replacing steel bar HRB concrete to upgrade electric poles, so that the ring shake problem of the electric poles is fundamentally solved, the labor productivity is improved, and the yield is free from limitation of a reinforcing mesh, and the product production quantity is improved to the greatest extent.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a small bending moment steel rod concrete pole, production equipment and a production process thereof. Background technique [0002] In the production process of existing small bending moment electric poles, the steel bar skeleton of the electric pole must be reinforced to form a welded mesh, and a welded mesh drawing machine must be provided. There are many solder joints. Taking Φ190-12m as an example, the solder joints reach 270 points. After the skeleton is formed, it does not meet the standard and needs to be adjusted. It takes an hour for 5 people to make a steel mesh. Based on 100 steel meshes, at least 10 people will invest in it every day. The labor intensity is high, the work efficiency is low, and the large power consumption seriously restricts the production quantity, which cannot solve the problem of ring cracking. Contents of the invention [0003] In order to solv...
