• Composition: the connector is composed of inner screw sleeve 1, inner screw sleeve 2, outer screw sleeve and lock nut.
• Features: the connection operation can be completed without rotating the reinforcement. It is especially suitable for the overall connection of bundled reinforcement with large positional error in building parts and reinforcement parts. The construction is convenient, reliable and low cost.

Connection between column reinforcement and section steel beam

1. Connection between vertical reinforcement and section steel beam

 

2. The column reinforcement is connected with the welding sleeve on the section steel beam. The non rotatable connection point in the middle adopts the double screw sleeve connection joint for in-situ connection

 

3. After the connection between column reinforcement and section steel beam is completed

 

4. The connection between column reinforcement and section steel beam is completed

Connection between reinforcement and section steel rigid column

1. The connection plate of section steel rigid steel column is abandoned and the mechanical connection welded sleeve is adopted

 

2. The reinforcement is connected with the welded sleeve on the section steel column

3. The reinforcement and the section steel column at the other end are connected with the welding sleeve through straight thread

 

4. After the reinforcement is connected with the section steel column respectively, the reinforcement in the middle cannot rotate. The double screw sleeve connection technology is adopted. During the connection, only the sleeve needs to be adjusted to complete the in-situ connection

 

5. Stirrup binding shall be carried out after the completion of in-situ connection

 

6. The connection of double threaded steel stiffening columns is completed

 

7. Close up picture after completion of double screw sleeve in-situ connection

 

Connection characteristics of reinforcement construction:

• There is no wet operation at the connection joint, and it is fully mechanically connected;
• The connection is fast and takes only 20 seconds. After the connection is completed, it can bear the force;
• Whether the reinforcement connection quality is qualified or not can be visually inspected, which is simple and clear;
• The field joint quality inspection is simple and fast, which is consistent with the ordinary straight thread joint;
• There is no need for other machines and equipment on the steel bar connection working surface, and only a connecting wrench is required.
