Rebar sleeve is also known as rebar joint: a connector used to connect rebar and has an internal thread corresponding to the thread of the thread. Simple construction process: the end of the steel bar is processed into a straight thread by a rolling process, and the two steel bars are connected to each other with the corresponding connecting sleeve.
Features of Rebar Coupler:
Rebar stripping and rolling straight thread connection is a new type of steel connection sleeve technology. Its structural principle is to peel off a part of the longitudinal and transverse ribs at the ends of the steel bars to be connected by cutting, and then directly roll them into ordinary straight After threading, it is connected with a special straight threaded steel connecting sleeve to form a steel connection.
The advantages of this connection method are as follows:
1. Good mechanical properties, safe and reliable connection: Because the end of the steel bar is formed by rolling and the material of the steel bar is cold-worked, the strength of the thread and the steel bar are improved, which makes up for the weakening of the strength of the thread base diameter being smaller than the base circle diameter of the steel bar The influence brought by the joint strength of the connection is higher than the strength of the base material, which can make the base material give full play to its strength and ductility.
2. Convenient connection: It can be operated flexibly in densely arranged steel bars in a small site. Convenient construction and high efficiency: the steel connecting sleeve is prefabricated in the factory, and the quality assurance: on-site rolling thread head equipment can process nearly 400 joints per shift, which has unparalleled advantages in the construction of large works and basement plates. , No pollution during construction, no open flame operation, safe and environmentally friendly, and can be constructed all-weather.
3. Convenient inspection: No special inspection equipment is required during construction, and the quality of the joint can be determined only by looking at the exposed wire teeth of the steel bar. Strong applicability: It is suitable for the steel connection of all seismic and non-seismic reinforced concrete structure projects, and it is suitable for bending steel bars, fixed steel bars, steel cages, extra-long steel bars and other occasions that cannot be rotated.

Classification of Steel Sleeve:
1. Standard connection
Possible free rotation conditions of use. The reason for using steel bars is mutually opposite to the vertex force that locks the bridge piece. Would like to choose standard sleeve or reduced-diameter connecting sleeve.
2. Extended connection
Used in occasions where the steel bars are too long and dense and inconvenient to rotate. The connecting sleeve is fully screwed into the elongated thread of a steel bar in advance, and then the end thread of the connected steel bar is screwed back, and the connecting piece can be locked by turning the steel bar half to one turn. A standard connecting sleeve can be used.
3. Locking female connection
It is used for the mutual butt connection of steel bars, such as bent steel bars, bridges, cast-in-place piles, etc., which cannot be rotated. Screw the lock nut and the connecting sleeve into the extended thread in advance, then screw in the thread of another steel bar end, and lock the connecting sleeve with the lock nut. Optional standard or flared connection sleeve plus lock nut
4. Positive and negative threaded connection
It is used in occasions where the steel bar cannot be rotated at all and the internal force of the steel bar needs to be adjusted, such as construction joints, post-pouring belts, etc. The connecting sleeve has positive and negative threaded fasteners. The two steel bars can be loosened or tightened in one rotation direction. The connecting sleeve with positive and negative threaded fasteners should be used first.
Applications of Steel Sleeve:
1. The use of steel connecting sleeves in the construction engineering industry can greatly reduce the use of materials, and the operation is simple and not restricted by the types of steel components.
2. The straight threaded sleeve has convenient, fast and simple connection, no electricity is needed for construction, weatherproof, and can be constructed all-weather.
3. It can connect horizontal, vertical and oblique HRB335, HRB400 same or different diameter steel bars.
4. Good anti-low temperature effect, passing the low temperature test of minus 40 degrees.
