High Quality Parallel Thread Connecting Steel Sleeve /Mechanical Rebar Splicing Coupler

Reinforcing steel sleeves are generally used in various steel lap jointing methods in the construction industry. The sleeve connection has the advantages of environmental protection and energy saving, saving building materials, stable quality, and strong adaptability to engineering construction, and the development trend is rapid. In particular, the technology of rolling straight threaded steel bar connection has already become the key way of mechanical connection of steel bars. The processing technology adopts the cold rolling processing technology to produce and process the top of the building steel bar into straight external threads.

After the building steel bars on both sides bear the force, the force transmission is completed according to the outer thread between the wire knot and the sleeve specification, and then the tensile force transmission between the two longitudinal steel bars is completed according to the connecting sleeve specification. It can be seen that the quality of the sleeve specification is immediately compromised. The quality of the connection of the construction steel bars at the construction site. The application of steel lap joint waterproof casing in the engineering and construction manufacturing industry can greatly reduce the application of raw materials, and the actual operation is simple. It will not be limited by the type of building steel prefabricated components.

The components can be prefabricated in advance, without occupying the construction period, and the production and processing efficiency is high. The straight thread sleeve is convenient, convenient and simple to connect, and there is no electricity in the construction, and the construction can be carried out 24 hours a day. It can connect horizontal, vertical and oblique HRB335, HRB400 same-diameter or different-diameter building steel bars. The production, processing and installation quality of the connector shall comply with the current standards and relevant national industry standards and construction acceptance specifications. The sleeve specification requires a product certificate, and the appearance quality and thread standards should comply with the regulations. Estimates, micrometers and thread plug gauges are selected for testing.

Reinforced straight thread sleeves are:
