Features of steel bar connection sleeve: 1. Use international No. 45 steel, special manufacturing process, high dimensional accuracy, reliable quality. 2. HRB335 and HRB400 ribbed steel bars which can connect 16-40mm. 3. Through the inspection by the National Construction Quality Supervision and Inspection Center, it reaches the I-level joint standard of JGJ107-2010. 4. There are 52 varieties of standard, positive and negative thread-fastening and special-diameter series, which can meet the requirements of the same-diameter, different-diameter and adjustable length and direction of the connecting reinforcement in the horizontal, vertical and oblique parts of the building structure.
The technical characteristics of steel bar connection sleeve: 1. It is suitable for the construction of steel bar connection in reinforced concrete structures of various structures under biaxial forces of tension and compression. 2. Save material, save energy, not subject to the constraints of the composition and variety of reinforcing bars. 3. It can be connected in all directions. 4. It can be pre-fabricated in advance, operated in factories, without occupying the time limit, and constructed all-weather. 5. Easy to operate, fast to construct, and can greatly shorten the construction period.
The strength of special joint of steel bar connection sleeve reaches the performance requirement of grade A joint in industry standard JGJ107-96. The threaded teeth have good shape, high precision and reliable connection quality. It has a wide range of applications and is suitable for 16-40 mm in diameter. Grade II and III steel bars are joined in the same and different diameters in any direction and position. Adjustable type: The positive and negative thread-fastening sleeve is suitable for the connection of reinforcing bars in the non-rolling places such as the steel cage of the Crutching iron and other reinforcing bars. Fast construction speed: thread processing early prefabrication and on-site processing, assembly construction. Energy conservation, pollution-free, safe and reliable construction.
In the construction industry, the traditional connection methods such as lapping and welding can not meet the needs of the rapid development of the construction industry, regardless of the quality, efficiency or operability of the connection. The continuous renewal of reinforcing bar connection sleeve skills has led to further innovation and continuous progress of skills in the whole industry. Therefore, the reinforcing bar connection skill is quite successful in a certain sense, and has its own characteristics, so as to adapt to the constantly developing industry and social trends. The overlap connection method can not be used for the connection of large standard steel bar, and there are many shortcomings in welding (such as unstable steel raw materials, poor weldability, unstable power supply or poor welder level, tight construction period, inadequate capacitance, climate impact, as well as the site construction plan of high fire-proof places; construction plan of horizontal steel bar; Quality and speed of connection. Welding quality can not be guaranteed. Reinforcing bar connection sleeve
Cohesion can avoid all these difficulties and show obvious advantages. In the late 1980s, by introducing advanced mechanical joining skills from abroad and the continuous efforts of experts from some scientific research institutes in China, the mechanical joining skills of reinforcing bars in China developed rapidly. Mechanical connection has gone through different stages of development, such as sleeve cold extrusion, taper thread, upsetting straight thread and rolling straight thread. The skill is constantly sophisticated and stable, and the cost is constantly decreasing.
The advantages of the new reinforcing bar connection sleeve are as follows: 1. It is not affected by many factors such as chemical composition of reinforcing bar, man-made factors, climate and electricity; 2. It is pollution-free, meets the requirements of environmental protection and is safe and reliable in construction without open fire operation; 3. It has a wide range of applications and is suitable for the connection of reinforcing bars of different orientations and sizes; 4. It has high strength, stable and reliable quality; 5. It is easy to operate. Slightly, the construction speed is fast.
