Steel connecting sleeve
 
First, use
A connector for connecting the reinforcing bars and having internal threads corresponding to the threads of the wire.
Second, the characteristics


Product Name: Straight threaded connection steel sleeve
Main Category: Sleeve
Product specifications: φ14mm-40mm
Production unit: Changzhou Zhongdong Machinery Technology Co., Ltd.
Product Remarks: Steel connecting sleeve straight thread connection sleeve steel sleeve mechanical connection
Material: high quality 45# carbon structural steel.
Scope of application: for the connection of HRB335, HRB400 steel bars
Appearance quality: threaded teeth are full, there is no crack on the surface of the connecting sleeve, and there is no serious rust on the surface and internal threads.
Eclipse and other visible defects. With a special thread plug gauge inspection, the plug gauge can be smoothly accessed.
◆ Equal strength joints, excellent fatigue resistance and low temperature resistance, higher than the strength of the base metal;
◆ The thread shape is good, the precision is high, there is no false thread, and the connection quality is stable;
◆ Wide application range, which can connect horizontal, vertical and oblique common diameter and different diameter steel bars;
◆ All-weather construction, prefabricated, easy to operate and shorten construction period.


Third, the type of steel connection sleeve and the requirements for use
 
1. Standard type: steel connection under normal conditions;
2. Positive and negative thread type: used for occasions where both ends of the steel bars cannot be rotated;
3, long thread type: steel can not be rotated at all, through the rotating sleeve to connect the steel;
4. Reducing type: used for connecting steel bars of different diameters.


 


 


Technical introduction
1. It adopts No.45 high-quality carbon structural steel, with reasonable design, advanced technology, high dimensional accuracy and reliable connection quality.
2. The basic parameters of each specification sleeve are all designed according to the strength requirements of HRB500 grade steel bars. It can be applied to HRB335, HRB400 and HRB500 grade rebar.
3. The performance indicators have been tested by the “National Construction Engineering Quality Supervision and Inspection Center” and all meet the requirements of “I” grade joints in JGJ107-2010.
4. The specifications are matched with the diameter of the connected steel bars, and are divided into ten kinds of specifications: φ14mm, φ16mm, φ18mm, φ20mm, φ22mm, φ25mm, φ28mm, φ32mm, φ36mm, φ40mm.
Technical characteristics
1. It is suitable for the connection of steel bars in various reinforced concrete structures subjected to the two-way force of tension and compression.
2, the connection is convenient, fast and easy to operate.
3. Easy to detect and intuitive.
4, steel processing straight thread can be prefabricated, can be factory production, does not occupy the construction period.
5, can be connected horizontal, vertical, diagonal HRB335, HRB400, HRB500 class of the same diameter and different diameter steel.
Scope of application
       It can be widely used in reinforced concrete structure engineering in steel bars in various industrial and civil buildings. Especially suitable for high-rise buildings, roads, bridges, subways, tunnels, power stations, dams and other steel structures such as explosion-proof and earthquake-resistant buildings and structures. It is suitable for the same or different diameter connection of HRB335, HRB400 and HRB500 steel bars of φ14-φ40 in beam, plate and column foundation in any position and in any direction. It can also be used as pre-embedded joint of steel bars.
