Difference between Threaded Rebar Coupler and Cold Extrusion Rebar Coupler

图片
Different Usage 1.  Threaded rebar coupler  is to peel off part of the longitudinal ribs and transverse ribs at the ends of the steel bars to be connected by cutting with a thread rolling machine, and then roll them into ordinary straight threads directly, and connect them with a special threaded sleeve. The technology is efficient, convenient and fast. 2.  Cold extrusion rebar coupler  connection is to put two bars into the rebar coupler, then use a cold extruder to extrude the connection sleeve radially, so that the coupler is cold plastically deformed and the steel bars are tightened. This connection method is used for grade II and grade III steel bars with a diameter of 16 to 40 mm, which are divided into radial extrusion and axial extrusion. Different Technology 1. Threaded rebar coupler relies on two pipe wrenches to tighten the steel bar and the casing to connect the two steel bars. 2. Cold extrusion rebar coupler is to squeeze the casing through the extrusion...

Practical Operation of Cold Extrusion Rebar Coupler

图片
Process principle: The  cold extrusion rebar coupler  connection is to put two bars into the rebar coupler, then use a cold extruder to extrude the connection sleeve radially, so that the coupler is cold plastically deformed and the steel bars are tightened, thereby causing shearing force to transmit stress loads. The actual operation of the extrusion coupler: 1. Marking a positioning mark and an inspection mark at the end of steel bar before the extrusion connection for the steel coupler would stretched after extrusion, the positioning mark enters the joint, so the mark is set to check whether the position of the steel coupler is correct. 3. When squeezing, it must be done from the indentation mark in the middle of the joint to both sides. 4. When extruding, the semi-finished product should be placed on a stand to prevent contamination in the extrusion cylinder. 5. The cold extrusion rebar coupler should be consistent with the specifications of the steel bar. When the steel ...
