Reinforcement sleeves are divided into the following types：
1. Standard type
Possible free rotation of the application. Use iron bars to lock each other opposite the end force of the bridge segment. Prefer standard sleeve or variable diameter connecting sleeve.
2. Extended type
It is used where the reinforcement is too long and dense to rotate. The connecting sleeve is screwed into the extended thread of a reinforcement in advance, and then reversely screwed into the end thread of the connected reinforcement. The connector can be locked by rotating the reinforcement for half to one turn. The standard connecting sleeve can be selected.
3. Positive and negative thread type
It is used where the reinforcement cannot rotate completely and the internal force of the reinforcement needs to be adjusted, such as construction joint, post cast strip, etc. The connecting sleeve is provided with positive and negative screw threads, and two rebars can be loosened or tightened in one screwing direction. The connecting sleeve with positive and negative screw threads shall be used first.
4. Reducing type
For connection of reinforcement with different diameters
