Advanced Rebar Coupler Connector Solutions for Metal Construction Needs

Product Description

Rebar Coupler

Steel Bar Coupler belong to the mechanical connection methods of steel bars and are suitable for the connection of large-diameter steel bars. They have the characteristics of energy conservation and no restrictions on the composition and type of steel bars.

Specification

Features of steel bar coupler:

1. Made of international No. 45 steel and with special manufacturing processes, they have high dimensional accuracy and reliable quality.
2. They can connect HRB335 and HRB400 grade ribbed steel bars with diameters ranging from 16 to 40mm.
3. They have been tested by the National Building Engineering Quality Supervision and Inspection Center and meet the Grade I joint standards of JGJ107-2010.
4. There are three series: standard type, positive and reverse thread type, and different diameter type, with 52 varieties, which can meet the connection requirements of steel bars of the same and different diameters and adjustable lengths and directions in various parts of building structures such as horizontal, vertical, and inclined directions.

Detail ways of Joint

I. Cone thread connection joint: A joint formed by the engagement of the specially processed cone thread at the end of the steel bar and the cone thread of the connection piece. The birth of the cone thread connection technology overcomes the shortcomings of the sleeve extrusion connection technology.

II. Straight thread connection joint
The straight thread connection joint mainly includes the straight thread connection joint after upsetting and the straight thread connection joint after rolling. These two processes use different processing methods to enhance the load-bearing capacity of the threads at the end of the steel bar, achieving the goal of the joint being as strong as the parent material of the steel bar.
Straight thread connection joint after upsetting: A joint formed by the engagement of the straight thread processed after upsetting the end of the steel bar and the thread of the connection piece. The process is as follows:

III. Sleeve extrusion connection joint: A joint formed by the plastic deformation of the steel sleeve of the connection piece under extrusion force and the tight engagement with the ribbed steel bar. There are two methods: radial extrusion connection and axial extrusion connection.

The advantages of the new type of steel bar Coupler

1. It is not affected by many factors such as the chemical composition of the steel bar, human factors, climate, and electricity.
2. It is pollution-free, meets environmental protection requirements, and is safe and reliable without open flame operation.
3. It has a wide range of applications and is suitable for the connection of steel bars in various positions and of the same and different diameters.
4. It has high strength and stable quality.
5. It is easy to operate, fast to construct, and can greatly shorten the construction period.

Technical features of steel bar coupler

1. It is suitable for the connection construction of steel bars in reinforced concrete structures of various buildings that are subjected to tensile and compressive forces.
2. It saves materials and energy and is not restricted by the composition and type of steel bars.
3. It can be connected in all directions.
4. It can be prefabricated in advance, allowing factory production, not occupying construction time, and enabling all-weather construction.
5. It is convenient and fast to operate, fast to construct, and can greatly shorten the construction period.
