Changsha DLADTO Rebar Splice Co., Ltd

Rebar couplers, also known as mechanical splices, join the lengths of two reinforcing bars together. The rebar coupler is roughly divided into  cold extrusion rebar coupler , straight thread rebar coupler, left and right-hand rebar coupler, welded rebar coupler, coupler with different inner diameters, etc. The application of mechanical splice has been very useful in some construction sites. But why are some prices high and others low?    The price of the rebar coupler is related to: 1. The price of the rebar coupler is related to its specification. Typically, there are 18, 20, 22, 25, 28, 32, and other specifications.     2. The price is related to the steel market. The ups and downs of rebar couplers follow the steel industry. 3. Th price is related to the quality of the  rebar coupler . The better the processing quality and the more the detection process is, the cost will be high and the price will be high. 4. The price is related to manufacturers. If the qualification certificate i

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 machine to clamp t

Steel Bar mechanical splices include various types: parallel threaded rebar coupler,   upsetting forged rebar coupler , cold extrusion rebar coupler, grouting rebar coupler, split-type rebar coupler and so on. Parallel threaded rebar coupler can be divided into rib stripped parallel rebar coupler and parallel threaded coupler for splicing rebars with threads roll on to rebar end. Regardless of the type of coupler, the specification is named after the specification of the steel bar to which it is connected. For example, the coupler connecting 25mm steel bar is called the 25mm coupler.  At present, the specifications of rebar couplers are 12, 14, 16, 18, 20, 22, 25, 25, 32, 36, 40, 50, and there are also left and right hand thread rebar coupler and coupler with different inner diameter. For example, 25/28 left and right hand thread rebar coupler; 28/22 different inner diameter  rebar coupler .  In the process of using mechanical splice, the specifications and models of the rebar coupler

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 bar chang
