Hebei Yida United Machinery Co. has been China's leading and professional manufacturer of rebar couplers and heads, parallel tappers, wire rollers and conical tappers, cold extruders, hydraulic tensioning machines for rebar, cutting tools, rollers and anchor plates since 1992.

Certified to the stringent ISO 9001:2008 quality control system and the CARES quality management system, which is accredited to BS EN ISO 9001 in the UK. Annual production capacity of couplings has increased from 120,000 to 15 million units.

Outstanding achievements in many major national projects such as the Karachi nuclear power plant in Pakistan, the Guinea hydroelectric power plant, the longest sea bridge Hong Kong-Macao-Zhuhai, the Soubré hydroelectric power plant in Côte d'Ivoire, etc.

1.Introduction

Hebei Yida Anti Impact Rebar Coupling system is a mechanical rebar splicing system, be made of high quality alloy steel. It has already passed the High Speed Tensile test of Anti instant impact by Germany Berlin BAM Laboratory. It has been widely applied at the sites where required high level of resistance to impact. The coupler sleeve will be perfect connected with rebar by cold swaged deformation in the application, and dual couplers will be connected by a high strength bolt.Its size can be from 12mm into 40mm different diameter bars.

Special Advantages：

（1）Each rebar is connected by cold swaged with a coupling, It was processed by large-tonnage hydraulic machine and unique split mould to ensure high quality and reliable radial deformation swage.

（2）Rebar sleeve bond press is done prior to site connection saving precious site time.

（3）The two sleeves are connected through a high-strength bolt, quality ensured.

（4）Installation on site is easy and fast, even in dense cages. No X-ray check is needed and installation can be done in any weather conditions.

（5）No thread cutting, no need heat or pre-heat on rebar, hence the rebar retains its original characteristics after splice.

（6）The Yida ACJ rebar coupling system stands complex or full tension as well as full compression state.

Hebei Yida Hydraulic Grip System Anti Impact Rebar Coupling system is divided into the following types：

（1）ACJ Standard Coupler

（2）BCJ Transition Coupler

（3）FCJ Positive and negative Thread Coupler

（4）KCJ Adjustable Coupler

（5）MCJ Anchorage Terminator Coupler
