Changsha DLADTO Rebar Splice Co., Ltd

1. Uniaxial tension of joints is the basic performance of strength and deformation; 2. High stress repeated tension and compression performance reflects the ability to withstand high stress repeated tension and compression under wind loads and small earthquakes; 3. The repeated tensile and compressive performance of large deformation reflects the mechanical performance of the joint when the steel bar enters the plastic deformation stage of the structure under strong shaking conditions. Changsha DLADTO Rebar Splice Co., Ltd   is a professional rebar coupler producer, we have been in this field for a long time with customers for all over the world. If you have any inquiry, welcome to contact us.

The principle of   rolling straight thread connection   is: the part to be connected of the steel bar is rolled into a thread and the connecting sleeve is connected with the steel wire head as a whole for realized the equal strength connection. This technology is suitable for 14-50mm diameter, HRB335 and HRB400 steel bars are connected with the same diameter and different diameters in any direction and can be used in various types of bridge structures. This process has some characteristics: (1) The joint strength meets the joint performance requirements in the industry standard JGJ107-2003. (2) The thread profile is good, the precision is high with stable and reliable connection. (3) Wide range of applications: suitable for connecting steel bars with a diameter of 14 to 50 mm in any direction. (4) Fast construction speed: thread processing is made in advance and on-site assembly operations are performed. (5) No pollution, safe and reliable construction. (6) Energy saving: The equipment

a)   Straight threaded rebar coupler   should be made of grade 45 round steel or seamless steel pipe and its mechanical properties and chemical composition should meet the requirements of GB/T 699 and GB/T 8162. Other steels also can be used and their mechanical properties should comply with the provisions of the corresponding national or industry standards and be confirmed by type inspection. b) Straight threaded rebar coupler need to be welded with structural medium-section steel and other steels, the material shall meet the requirements for welded ability.

1. The steel connecting sleeve is able to reduce the use of materials and easy to operate which not limited by the types of steel components. 2. The  straight threaded sleeve  can be connected conveniently, quickly and simply, they not need electricity in construction. 3. They can connect horizontal, vertical and oblique HRB335 and HRB400 steel bars of the same diameter or different diameter. The specifications and models of straight-threaded steel bar connection sleeves that our factory can produce are φ14-φ40 ordinary steel bar connection sleeves, adjustable steel bar connection sleeves, different diameter steel bar connection sleeves, and special steel bar connection sleeves. And provide wire rolling machine products of steel straight thread processing equipment.
