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.

在建筑行业中，传统的钢筋衔接方法如搭接、焊接等衔接方法，不管从衔接质量、效率仍是可操作性均不能满足建筑业迅速发展的需求。钢筋衔接套筒技能的不断更新带动了整个行业的进一步革新和技能的不断进步。所以钢筋衔接技能在必定意义上是相当成功的，并且具有自己的特色，这样才干适应不断发展的行业和社会潮流。搭接的衔接方法已不能用于大标准钢筋的衔接，再加上焊接有许多不足之处，（如钢材原料不安稳、可焊性差等状况；电源不安稳或焊工水平较差的状况；工期紧、电容量不够的状况；以及风雨冰冷等气候影响；还有防火要求高的场所的施工计划；水平钢筋的现场衔接的质量和速度。）焊接质量均无法保证。

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

衔接能避开上述种种困难，显示出明显得优势。80年代末期，通过引进国外的机械衔接技能，再加上我国一些科研院所的相关的不断努力，我国钢筋机械衔接技能得以发展迅速。机械衔接经历了套筒冷挤压、锥螺纹，镦粗直螺纹直到目前滚轧直螺纹等不同的发展阶段，技能不断老练安稳，成本也不断降低。

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.

新型钢筋衔接套筒的长处有以下几个方面：1、不受钢筋的化学成分、人为要素、气候、电力等许多要素的影响；2、无污染，契合要求、无明火操作施工牢靠；3、适用范围广，适用于各种方位及同、异径钢筋的衔接；4、强度高，质量安稳牢靠；5、操作简略，施工速度快。

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.
