1. Standard connection
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 connection
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. Lock female connection
It is used for the mutual docking of bending reinforcement, bridge, cast-in-place pile and other reinforcement cages. Screw the lock nut and the connecting sleeve into the extended thread in advance, and then screw in another rebar end thread, and lock the connecting sleeve with the lock nut. Standard or flared connecting sleeve with lock nut can be selected.
4. Positive and negative screw connection
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 reinforcement sleeve is provided with positive and negative screw threads, and two reinforcements can be loosened or tightened in one screwing direction. The connecting sleeve with positive and negative screw threads shall be used first.
