Principles
By adopting the special pressing machine to press the coupler laterally, the steel coupler is plastically deformed and combined closely with the deformation rebar, and therefore, the splicing of rebar is realized.

Features
*High splice strength, which could exert fully the tensile and compression strength of rebar, it could satisfy the requirements stipulated in the Chinese standard JGJ107,American standard UBC1997, British standard NF35-20-1,German standard DIN1045,ISO/WD15835(Draft)and other requirement in the relevant standard home and abroad;
* Simple operation, no need for technicians, fast splicing on construction site;
* Low power capacity, no power capacity restrictions on the construction site;
* Environment-friendly, safe, no environmental and weather restrictions.
