Rebar mechanical anchorage is a basic technology for all kinds of concrete structure engineering, and the reinforcement of steel bar needs to be anchored in order to secured its strength .Through the headed bars of anchor plate to increase the friction between the concrete and steel, improve its ability to resist drawing, in case of steel was pulled out,instead of bent ends.It is approach greatly simplifies rebar placement and reduces congestion .Rebar End Anchor Plate is ideal for all forms of construction, including: Nuclear Powerplant ,subways, bridges, dams, high-rises building, water treatment plants, stadiums ,Airport. Rebar Mechanical Anchor Plate is widely applied used for Column-beam Joint and Roof/Column ,Anchor bolts applications.
Installation of Rebar Mechanical Anchorage:
Step 1:Threaded on Rebar Ends by Mechanical Splicing machine

The Cold Extrusion Machine is made up by a hydraulic Clampy with Cold Pressing Dies and Hydraulic Oil Pump.
The features of this technology:
1.Strong intensity connector, stable and reliable; no specific requirements on the weld ability of the rebar;
2.Only needs 1-3m to stamp each connector, which is about ten times faster than ordinary welding;
3.Only 1-3 kw power of oil pump , which is not limited by power capacity, has flexible structure and suitable for operation on several machines;
YJ650 stamping equipment
4.No flammable gases, not affected by rainy or cold weather;
5.Relieve congestion of the connecting point, facilitated concrete pouring;
6.No professional and experienced worker needed, able to connect changed steel bar of different diameters;
7.Save 80% of connector steel consumption.
The technology is assessed by the Ministry of Construction as "world advanced, high quality, high efficiency, safe, and economical thick diameter distorted steel bar connection technology which can be widely used in the construction industry."
Standard taper thread couplers are designed to splice the same diameter bars where one bar can be rotated and the bar is not restricted in its axial direction.It is designed to achieve failure loads in excess of 115% of the caracterisitc strength of grade 500 rebar end.
Transition taper thread couplers are designed to splice different diameter bars where one bar can be roated and the bar is not restricted in its axial direction.
Taper thread working principle:
1.Slice up the end of the rebar;
2.Make the rebar taper thread cutted by taper thread machine.
3.Connect together two taper thread end by one piece of taper thread coupler.
Taper thread position couplers are designed to quickly splice column sections or precision coupling of elements with multiple bars jointed over a short span, such as prefabricated elements, and the closing of small temporary openings.
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.
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.
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.
The material of the cold extrusion rebar coupler is no.20 steel.
