Description

Technical Field

[0001] The utility model relates to the technical field of construction safety, in particular to a simple appearance detection plate for an electroslag pressure welding head. Background Art

[0002] In modern construction, the stability and safety of reinforced concrete structures are crucial, and reliable connections between steel bars are the basis for ensuring the strength of the overall structure. As a common method for connecting steel bars, electroslag pressure welding is widely used in bridges, high-rise buildings and other projects because of its easy operation, high welding efficiency and excellent joint mechanical properties. However, the quality of electroslag pressure welding joints directly affects the durability and bearing capacity of the entire structure. Therefore, strict control of the appearance and internal quality of the joints is essential.

[0003] At present, when using electroslag pressure welding for steel bar connection, manual visual inspection and traditional measuring tools (such as vernier calipers, angle rulers, etc.) are mainly used to check whether the weld appearance meets the specification requirements, including key indicators such as weld height, steel bar bending angle, and steel bar axis deviation. However, this process has the following limitations:

[0004] 1) Subjectivity: Manual inspection relies on the experience and judgment of the inspector. Different inspectors may have different judgment standards, which limits the repeatability and accuracy of the inspection results.

[0005] 2) Accuracy limitation: Traditional manual tools have difficulty meeting high accuracy requirements when measuring small dimensional changes (such as weld height exceeding 4mm above the steel bar surface, steel bar axis offset not exceeding 0.05d and not greater than 1mm), especially when the lighting conditions are poor or the weld position is difficult to access;

[0006] 3) Inefficiency: Manually checking each weld joint one by one is time-consuming and laborious, especially in large-scale construction projects, which not only delays the construction progress but also increases labor costs;

[0007] 4) Difficulty in dispute resolution: Due to the above-mentioned issues of subjectivity and accuracy, there are often disagreements between the construction unit and the supervision unit on whether the quality of the joints is qualified. There is a lack of rapid and objective basis for judgment, which affects the progress of the project and the atmosphere of cooperation.

[0008] Therefore, there is an urgent need for a device that can efficiently, accurately and objectively check the appearance quality of the electroslag pressure welding joint to solve the above problems. Utility Model Content
