Description

Technical Field

[0001] This utility model belongs to the technical field, and in particular relates to a steel bar straightening device for building construction. Background Technology

[0002] Reinforcing steel bars possess significant advantages such as high strength, good toughness, strong plasticity, and excellent durability, and are widely used in many key fields such as building structures, bridge engineering, transportation facilities, and water conservancy and hydropower. However, with increasingly stringent quality requirements for reinforcing steel bars in modern engineering construction, problems such as bending deformation and dimensional deviations that easily occur during production and transportation are gradually becoming insufficient to meet specific construction needs. Straightening technology, as an effective modification process, optimizes the straightness of reinforcing steel bars through mechanical straightening, hydraulic methods, and other means, effectively improving the service life, performance stability, and construction adaptability of the reinforcing steel bars.

[0003] However, in the use of existing rebar straightening devices, the straightening device adjusts the squeezing force of each individual roller separately, which can easily lead to the phenomenon that the squeezing force of the other rollers is different from that of the rebar. This causes the rebar to deviate and twist due to uneven squeezing force from multiple rollers during the straightening process, making it difficult for the rebar to be evenly stressed and causing bending. This affects the appearance and quality of the product and reduces efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a rebar straightening device for building construction. By setting up a straightening section, it solves the problem that in the existing rebar straightening device, the straightening device adjusts the squeezing force of each roller individually, which easily leads to different squeezing forces among multiple rollers. This causes the rebar to deviate and twist during the straightening process due to uneven force, making it difficult to bear force evenly, resulting in bending, which affects the appearance and quality of the product and reduces efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
