Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a handheld steel bar rust removal device for construction engineering. Background Art

[0002] A construction project refers to an engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. Steel bars are often used in the field of construction projects. Sometimes it is necessary to pre-embed and reinforce the steel bars with concrete, and expose the upper ends of the steel bars to facilitate docking with building components installed later.

[0003] However, when the construction period is long, the exposed parts of the steel bars are prone to rust. Currently, spraying rust removers is commonly used for rust removal, but this rust removal method is relatively simple and the rust removal effect is not ideal. Based on this, we propose a handheld steel bar rust removal device for construction projects for improvement. Utility Model Content
