Abstract

The invention discloses a fabricated part for delaying the corrosion of works corner steel and a use method of the fabricated part. The fabricated part comprises a fabricated part body made from high-performance cement-based material which has main characteristics of super high toughness and high elongation, the fabricated part body is applicable to a template and a works corner, the fabricated part body takes the intersecting line of the works corner as a centre line, two sides of the fabricated part body are respectively a section of wing plate which outwards extends from the centre line, the inner wall surface of each wing plate is fit with the outer wall surface of the corresponding works corner, and the inner wall surface of each wing plate is provided with a steel bar protection layer filler strip which has a certain distance and of which the length direction is accordant with a pouring direction of the concrete. The fabricated part can not only delay the corrosion of the works corner steel, but also is beneficial for reducing the daily maintenance cost of a works, and has the characteristics of being convenient to install, prominent in effect, etc.

Description

technical field [0001] The invention relates to a prefabricated part for delaying the corrosion of steel bars at the corners of structures, and a method for using the prefabricated parts for delaying the corrosion of steel bars at the corners of structures; it is mainly used for delaying the corrosion of steel bars at the corners of concrete structures and improving the durability of structures performance and reduce daily maintenance costs. Background technique [0002] For concrete structures with non-circular sections, the steel bars at the corners are bent to a certain extent, and the tensile area of ​​the steel bars has reached a high level of tensile stress. Most of the corners of the structure are also the joints of the formwork. The quality of the concrete is often low, and the thickness of the protective layer of the steel reinforcement is too small due to the improper arrangement of the protective layer pads. In addition, the external erosive medium can invade the ...
