What Is the Connection Standard of Rebar Coupler?

图片
The qualified standards for the rebar coupler are as follows: 1. The  rebar coupler  is made of 45 high-quality carbon structural steel with reasonable design, advanced technology, high dimensional accuracy, and reliable connection quality. 2. The basic parameters of rebar couplers are designed in accordance with the strength requirements of HRB500 steel bars, and also can be applied to HRB335 and HRB400 rebars. 3. The performance indexes of the rebar coupler have been tested by the "National Construction Engineering Quality Supervision and Inspection Center", and all of them meet the requirements of the "I" class joint in JGJ107-2016 Technical Regulations on Mechanical Connection of Rebar. 4. The specifications match the diameter of the connected steel bar, being divided into ten regular specifications: φ14mm, φ16mm, φ18mm, φ20mm, φ22mm, φ25mm, φ28mm, φ32mm, φ36mm, φ40mm, as well as special specifications: φ10mm, φ50mm. 5. Three series (standard rebar coupler, lef

Installation Steps of Parallel Threaded Rebar Couplers

The parallel threaded rebar coupler connection is that a part of the longitudinal and transverse bars at the end of the steel bar is cut and peeled by a wire roller and it is rolled directly into ordinary parallel threads, then the special  parallel thread rebar coupler  is applied to form a steel bar connection. The technology of rib stripping rolling parallel thread connection has reached the advanced international level. Rib-stripped parallel threaded coupler connection technology is favored by the majority of construction units and owners due to its advantages of convenient construction, energy saving and consumption reduction, improved production efficiency, and stable and reliable connection quality. It is a new product of parallel thread connection technology. When using the parallel steel thread coupler, pay attention to installation precautions to avoid unnecessary technical problems that may affect the quality. 1. Steel bars in place: Move the steel bars that have passed the

Whole Grouting Sleeve Vs. Half Grouting Sleeve

Advantages of   whole grouting sleeve   compared to half grouting sleeves: 1. Under the condition that all performances can be met, the grouting sleeve pressed by special equipment and special process is lower in cost and easy to use compared with the grouting sleeve processed from bar material and the sleeve cast by ductile iron. (2) When prefabricating components in the factory, the steel bar can be directly inserted into the sleeve, which saves the some steps if use half grouting sleeve, like threading and tightening the half grouting sleeve. The installation is fast and convenient, and the positioning accuracy can meet the standard requirements of use; (3) Both ends are connected to the steel bar through high-strength grouting material, so the connection quality at both ends of the joint can be effectively guaranteed.
