Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a welding-free steel bar connector. Background Art

[0002] The connector is a kind of steel bar connection material, which is actually a steel sleeve with threads inside. According to the thread form, it can be divided into tapered threads and straight threads. During construction, the connector is installed on the reserved steel bars on the underground continuous wall steel cage. After the excavation is completed, the main floor reinforcement can be connected to the connector. The connector on the steel cage is installed on the anchor bar by special equipment. When constructing the base plate, one end of the steel bar is rolled into a thread, and then screwed to the connector with a wrench to achieve the form of steel bar connection.
