What is the Structural Principle of Rib Rolling Threaded Rebar Coupler

Rib rolling threaded rebar coupler connection is a new type of steel connecting sleeve technology. Its structural principle is to peel off a part of the longitudinal and transverse ribs at the end of the steel bar, and then roll them into a ordinary bar after connected, use a special straight-threaded steel bar connecting sleeve to connect them. 



It can be operated flexibly in narrow place. Convenient construction and high efficiency: steel bar connection sleeves are prefabricated in the factory. Quality assurance: on-site rolling wire head equipment can process nearly 400 joints per shift, which has unparalleled advantages in the construction of large quantities. No pollution during construction, safety and environmental protection, and can be work in all weather.


Changsha DLADTO Rebar Splice Co., Ltd is a professional rebar coupler producer, we have been in this field for a long time with customers for all over the world. If you have any inquiry, welcome to contact us.

1   Remove the  eccentric bushing  and eccentric shaft from the thread holder, loosen the screws first, and then use a special wrench for the eccentric bushing to rotate the eccentric bushing 180 degrees . Then, place the loosened screws into the screw hole after the rotation of 180 degrees and tighten them (the rolling head and rib stripping head are equipped with 3 eccentric bushing, each with a 180 degree rotation, and tighten them by changing the screw hole). 2 Install the threading roller and place it counterclockwise in 1-2-3  (POSITIVE THREAD)    Install the threading roller and place it anticlockwise in 3-2-1  (NEGATIVE THREAD) 3 Upper the rib stripping machine head, tighten the screws, adjust the test bar, and start working

Several Advantages of Using Straight Threaded Steel Bars

图片
1. The steel connecting sleeve is able to reduce the use of materials and easy to operate which not limited by the types of steel components. 2. The  straight threaded sleeve  can be connected conveniently, quickly and simply, they not need electricity in construction. 3. They can connect horizontal, vertical and oblique HRB335 and HRB400 steel bars of the same diameter or different diameter. The specifications and models of straight-threaded steel bar connection sleeves that our factory can produce are φ14-φ40 ordinary steel bar connection sleeves, adjustable steel bar connection sleeves, different diameter steel bar connection sleeves, and special steel bar connection sleeves. And provide wire rolling machine products of steel straight thread processing equipment.

Problems Encountered During Rebar Coupler Processing

图片
 Rebar coupler is also known as mechanical splices in the construction industry. The common specifications of the  rebar coupler  are M12, M14, M16, M18, M20, M22, M25, M28, M32, M36, and M40. The most commonly used specifications are M16, M18, M20, M22, M25, M28, and M32. These are the most used on the site, but also the most commonly used. Today, we will introduce to you how to solve the wrong diameter or length problems encountered in the processing of steel sleeves.  Causes:  1. The specifications of raw materials are not accurate, and the feeding speed is too slow. 2. Raw materials are bent and not straightened before processing. 3. The mechanical equipment malfunctioned, resulting in the diameter of the rebar coupler becoming smaller. 4. Operators do not process according to engineering drawings.   Solutions: 1. Adjust raw material specifications and models, and pre-feed appropriate amount. 2. Straighten the round bend steel before cutting the raw material. 3. Check the mechanica
