Anonymous users2024-02-10Rebar sleeves are usually produced with precision steel pipes. The precision steel pipes used specifically for the production of rebar sleeves are made of 45 steel, often referred to as "rebar connection sleeves".
Rebar sleeve, also known as rebar joint: a connector used to connect rebar and have an internal thread corresponding to the thread of the wire head.
Classify. There are six types of rebar sleeve connections: (variable diameter type, flaring type will not be introduced here).
1. Standard connection.
The use of possible free rotation cases. Iron rod reasons are used opposite each other opposite the endpoint force of the lock bridge piece. Prefer a standard sleeve or a reducer connecting sleeve.
2. Extended connection.
It is used for occasions where the steel bar is too long and dense, and it is inconvenient to rotate. The connecting sleeve is screwed into the extended thread of a steel bar in advance, and then the end thread of the connected steel bar is reversed, and the connector can be locked by rotating the steel bar for half to one turn, and the standard connecting sleeve can be selected.
3. Locking female connection.
It is used for the steel bar that cannot be rotated at all, such as the mutual docking of bending steel bars and steel cages such as bridges and cast-in-place piles. The lock nut and the connecting sleeve are pre-screwed into the extension thread, and then screwed in another rebar end thread, and the connecting sleeve is locked with the lock nut. Standard or flared connection sleeves are available with locking nuts.
4. Positive and negative thread connection.
It is used for occasions when the steel bar cannot rotate at all and requires the adjustment of the internal force of the steel bar, such as construction joints, post-pouring belts, etc. The connecting sleeve has a positive and negative thread buckle, which can loosen or tighten two steel bars in one screwing direction, and the connecting sleeve with a positive and negative thread buckle should be used first.

Anonymous users2024-02-08There are no hard and fast rules.
In the construction of steel engineering, the mechanical connection is commonly used in the threaded connection, and the sleeve extrusion connection is not commonly used. The range of use of threaded connection is more than 16 steel bars, which are divided into two types: tapered thread connection and straight thread connection.
The cone thread connection is divided into grade and grade taper thread sleeve joint, and its difference is that the processing of grade cone thread joint is directly at the end of the raw material to make a tapered outer wire with sleeve connection.
The grade taper thread joint is to first upset the end of the raw material, and then make a tapered outer wire at the upsetting part and connect it with a sleeve, which can be as strong as the raw material; Straight threads are divided into four types: upsetting straight threads, direct rolling threads, extruded rib rolling threads and stripping rib rolling threads.
