System D: Cold Forged Sleeve Splicing for Ribbed Rebar 

Principle:

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

Features:

1) High splice strength, which could exert ultimate tensile and compression strength of rebar, it could satisfy the requirements stipulated in the Chinese standard JGJ107, American standard UBC1997, British standard BS8110, French standard NF-35-20-1, German standard DIN1045, ISO15835 and other requirements in the relevant standards;

2) Easy to operate and maintain, no need for technicians, fast splicing on construction site;

3) Low power capacity, no power capacity restrictions on construction site;

4) Environment-friendly, safe, no environment and weather restrictions. 

5) Full-Tension splice, bar break under tensile tests.

6) Inexpensive to purchase, maintain and repair. 

7) Manufactured under strict quality assurance plan ISO 9001.

General Regulations:

1. Cold swaging rebar splicing can be used for rebar splicing in concrete structure in different directions. Rebar is from 16mm to 40mm.

2. It is convenient to use swaging rebar splicing as described below:

1) When the requirement of rebar splicing strength and anti-fatigue performance is very high; 

2) Splicing of rebar with bad solderability.

3. Cold swaging splicing can be used for rebar of both same diameter and different diameters. When the diameter difference of rebar is no more than 5mm, the same coupler listed in Table 2 can be adopted.  When the diameter difference is more than 5mm, varied diameter coupler should be used. In this condition, the testing of rebar splicing should be evaluated as per the requirement for minor diameter coupler.
