The stability of the Rebar Couplers. Technical direction In the construction industry, the traditional steel connection methods such as lap, welding and other connections, both from the connection quality, efficiency or operability can not meet the rapid development of the construction industry needs. The continuous upgrading of the steel connection sleeve technology has led to further innovation and technological progress in the industry as a whole. So the bar connection technology in a certain sense is quite successful, and has its own characteristics, so as to adapt to the continuous development of the industry and social trends. Lap connection can not be used for large-size steel connections, coupled with welding there are many shortcomings, (such as steel material instability, poor solderability; power supply instability or poor welder level; Tight, the capacity of the situation is not enough; and the cold weather and other climate effects; there are high fire safety requirements of the construction program; level of steel field connection quality and speed.) Welding quality can not be guaranteed. Reinforcement mechanical connection can avoid the above difficulties, showing obvious advantages. The late 80s, through the introduction of foreign advanced mechanical connection technology, coupled with some of our research institutes of the relevant experts continue efforts, China's steel machinery to connect the technology to develop rapidly. Mechanical connection has experienced a cold extrusion, taper thread, upsetting straight thread until the current rolling straight thread and other different stages of development,Rebar Couplers technology continues to mature and stable, the cost is also reduced. 2, no pollution, in line with environmental requirements, no open fire operation of the construction of safe and reliable; 2, no pollution, in line with environmental requirements, no open fire operation safe and reliable; 2, no pollution, 3, for a wide range, for a variety of directions and the same, different diameter steel connection; 4, high strength, stable and reliable quality; 5, simple operation, construction speed
Characteristics and technical characteristics of Rebar Couplers
Rebar connection sleeve features: 1. The use of international 45 steel, special manufacturing process, high dimensional accuracy, reliable quality. 2. Can connect Ф16-Ф40mm HRB335 grade and HRB400 grade ribbed steel bar. 3. After the National Construction Quality Supervision and Inspection Center testing, to JGJ107-2010 in the I-level connector standards. 4. Standard type, positive and negative silk type,Rebar Couplers different diameter three series, fifty-two varieties, to meet the building structure in the horizontal, vertical, oblique and other parts of the same diameter, different diameter and adjustable length and direction Of the demand for connecting steel.
The technical characteristics of the Rebar Couplers are as follows: 1. Applicable to the construction of reinforced concrete in reinforced concrete structure of all kinds of structures subjected to pull and press force. 2, materials, energy saving, not subject to steel composition and types of restrictions. 3, can be all-round connection. 4, can be prefabricated in advance, factory operations, do not take the construction period, all-weather construction. 5, easy to operate, fast, fast construction, can greatly shorten the duration
Rebar connection sleeve Technical characteristics Joint strength to meet the industry standard JGJ107-96 in the A-level connector performance requirements. Thread profile good, high precision, stable and reliable connection quality. Wide range of applications, suitable for diameter 16-40mm. Ⅱ, Ⅲ grade steel bars in any direction and position of the same diameter connection. Adjustable type: positive and negative thread-type sleeve for steel bars and other steel can not change the connection of steel bars. Construction speed: thread processing in advance prefabricated and on-site processing, assembly construction. Saving energy, pollution-free, safe and reliable construction.
