Grip tec rebar coupler

详情

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.

ACJ Standard Coupler
ACJ standard coupler is made up by two standard sleeves and one standard bolt, suitable for same diameter rebar connecting. The Yida ACJ is suitable for general application such as beams or walls where the rotation of the rebar is possible. Screw the bolt into one sleeve firstly, then rotate one rebar to screw the other bolt end into the other sleeve.

Characteristic: ACJ coupler uses standard female (sleeve) only, making rebar press more efficient as there is no need to specify different sleeves.

Application Guide:
Proper installation is very important to ensure the design load will be reached in the application. Yida strongly recommends that the installation and site quality check be done according to the required guidelines and dimensions.

● Rebar And sleeves swaged connection
Using hydraulic machine and unique split mould to swage sleeve deformation, formed the seamless connection with rebar and the swage length is to meet the standard swage length. Shorter swage length reduces the bond, while longer swage length may shorten the engagement length of the thread.

● Site installation method
Step 1:Screw the bolt into female coupler swaged with rebar, till unable to screw continually.
Step 2:Screw another side of bolt into the other sleeve after swaged with rebar, till unable to screw continually.
Step 3:With help of two pipe wrench, tighten the connection by turning both rebar / couplers in opposite direction at the same time.
