摘要： Disclosed are a length-determined standardized reinforcing bar integrated with a butt joint device, and a method of constructing a reinforcing bar structure by using the same, wherein after determining a material and a diameter of a reinforcing bar, a determined standardized length measurement, which is a length standard from one end to the other end, is determined and imparted to a reinforcing bar to be cut, and the reinforcing bar is cut to a determined standardized length in accordance with the imparted length measurement, and once the type of a butt joint device for butt-jointing the reinforcing bar cut to the determined standardized length is determined, the butt joint device is formed at, and integrated with, one end or both ends of the reinforcing bar cut to the standardized length by the determined standardized length.

摘要： A stud-weldable rebar and a method for making the rebar are disclosed. The rebar has a steel body with a weld end and a diameter that is substantially uniform along a length of the body. A tip portion at the weld end includes a hardened zone and a base portion is formed of the remaining steel body. The hardened zone has a hardness that is about 1.5-3.0 times greater than a hardness of the base portion. Induction hardening is used to form the hardened zone.

摘要： This invention discloses an anti-corrosion coating sintered at low temperature for steel rebars. The composition of coating includes 30-50 weight percent nano-silica, 20-40 weight percent flux, 9-20 weight percent calcium fluoride, 2-10 weight percent thickener, and 2-14 weight percent adhesion, agent. This invention also discloses the coating method of above-mentioned anti-corrosion coating. The method includes seven steps: 1. dry mixing, 2. wet mixing, 3. pretreatment, 4. coating, 5. baking, 6. sintering, 7. cooling down at room temperature. The coating of this invention has high strength, high density, high corrosion resistance, good capacity to bond with concrete, and maintains the mechanical properties of steel rebars.
