Big discounting Reinforced Bellows Expansion Joint - MCJ Anchorage Terminator Coupler – YIDA

1.Hebei Yida Anti Impact Rebar Coupling system is divided into the following types：

（1）ACJ Standard Coupler 2.1

（2）BCJ Transition Coupler 2.2

（3）FCJ Positive and negative Thread Coupler 2.3

（4）KCJ Adjustable Coupler 2.4

（5）MCJ Anchorage Terminator Coupler 2.5

2. 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.

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. Connection of rebar with coupler after swaged as shown in Figure 1.

Figure 1

（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.

2.5 MCJ Anchorage Terminator Coupler

MCJ Anchorage Terminator Coupler is made up by one standard sleeve, one standard bolt, and one standard anchorage terminator coupler (as shown in Figure 16),used for the connection between rebar and anchorage terminator coupler. It can be used when need using anchorage terminator coupler to connect with rebar.

Figure 16

Characteristic：MCJ Coupler is using standard sleeve, standard bolt to make the rebar connected with anchorage terminator coupler so that can satisfy the anti impact requirement.

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 standard bolt into female coupler swaged with rebar, till unable to screw continually. As shown in Figure 17.

Figure 17

Step 2: Screw the anchorage terminator coupler into standard bolt, make the anchorage terminator coupler keep touch with female coupler. As shown in Figure 18.

Figure 18

Step 3: With help of two pipe wrench, tighten the connection by turning both two sleeves in opposite direction at the same time.
