The Specifications and Models of Rebar Coupler

 Rebar coupler are divided into parallel threading rebar coupler, cold extrusion rebar coupler, upsetting forged rebar coupler, split rebar coupler, grouting rebar coupler, etc. Regardless of the type of rebar coupler, they are named by the size of the steel bar it is connected to.



At present, the specifications of the rebar coupler are 12, 14, 16, 18, 20, 22, 25, 25, 32, 36, 40, 50, and there are also positive and negative wires and reducer rebar coupler, such as: 25 positive and negative wires, 28 positive and negative wire, 28/25 reducing rebar coupler, 28/22 reducing rebar coupler, etc.


The common specifications of the steel connecting sleeves produced are Φ12, Φ14, Φ16, Φ18, Φ20, Φ22, Φ25, Φ28, Φ32, Φ36, Φ40. the size can be customized as required.

Tensile Strength Test of Rebar Coupler

图片
Rebar Coupler is designed to produce a full-strength mechanical joint between reinforcing bars. Today, I will share with you how to detect the tensile strength of the  rebar coupler . Let's get a close look. 1. Process Inspection Before and during the construction of the steel bar connection project, conduct a process inspection for each batch of incoming splices. There shall be no less than 3 splices of each type of steel bar during process inspection. The base material of the splice specimen shall be taken tensile strength test. 2. On-site Inspection The on-site inspection of splices shall be carried out according to the acceptance batch, and the joints of the same grade, type, and specification of the same batch of materials shall be adopted under the same construction conditions. An acceptance batch of 500 will be conducted for inspection. For each acceptance batch of splice, three specimens must be randomly selected from the engineering structure for unidirectional tensile tes

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

Product Description for Reducing-diameter Steel Connecting Sleeve

图片
The   reducing-diameter steel connecting sleeve   is used for special engineering. One end of the sleeve is a screw thread connecting thick steel bars and the other end is a screw thread connecting thin steel bars. A steel connection sleeve with a diameter of 28 to 25 is required. Features of reducing diameter steel connecting sleeve: 1. The diameter-reducing steel connecting sleeve can reduce the materials and is easy to operate, also they are not limited by the types of steel components. 2. The steel connecting sleeve can be prefabricated in advance, which does not occupy the construction period and has high processing efficiency. 3. The connection is convenient, fast and simple, can construct in all weather. 4. It can connect horizontal, vertical and oblique HRB335 and HRB400 steel bars of the same diameter or different diameter.
