The steel bar connecting sleeve

In the construction industry, the traditional reinforcement connection methods, such as lap joint and welding, can not meet the needs of the rapid development of the construction industry in terms of connection quality, efficiency and operability. The continuous updating of reinforcement connecting sleeve technology has driven the further innovation and technological progress of the whole industry. Therefore, the reinforcement connection technology is quite successful in a certain sense, and has its own characteristics, so as to adapt to the developing industry and social trend. The overlapping connection method can no longer be used for the connection of large-size reinforcement. In addition, there are many deficiencies in welding, (for example, unstable steel material and poor weldability; unstable power supply or poor welder level; tight construction period and insufficient capacitance; weather effects such as wind, rain and cold; construction scheme for places with high fire protection requirements; quality and speed of on-site connection of horizontal reinforcement.) The welding quality cannot be guaranteed. The mechanical connection of reinforcement can avoid the above difficulties, showing obvious advantages.


The steel bar connecting sleeve is made of international 45 steel with special manufacturing process, high dimensional accuracy and reliable quality. Connectable Ф 16- Ф 40mm HRB335 and HRB400 ribbed reinforcement. At the same time, it has also been tested by the national construction engineering quality supervision and inspection center and reached the class I joint standard in JGJ 107-2016. There are three series of standard type, positive and negative screw thread type and reducing type, with 52 varieties, which can meet the requirements of connecting reinforcement with the same diameter, reducing diameter and adjustable length and direction in the transverse, vertical and oblique parts of the building structure.
