Binding, Welding and Mechanical Connection

Types of rebar connection: binding, welding, mechanical connection.


1. Binding and overlapping: the overlapping of steel bar is tie two steel bars with wire bindling. The connection method is suitable for the connection of steel bars with smaller diameters. It is used for reinforcement mesh in concrete, the warp and weft are evenly arranged.



2. Welding connection: welding connection of steel bars is divided into three types: arc welding, electroslag pressure welding and flash butt welding. Each type of welding must be sent for trial welding. In principle, the test welding problem requires all welding specifications and types used in this project, and each welder must make a set of test pieces.


3. Mechanical connection: mechanical connection generally refers to the rebar sleeve connection, which is mostly used for wall columns and beams. It is to process the end of the steel bar into a straight thread by rolling process, and connect the two steel bars with rebar coupler.

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
