2. Sleeve is a kind of water supply pipe connecting accessories, which can be used for the connection of steel pipe and cast iron pipe. Steel bar connection sleeve is a special product for mechanical connection of steel bars, which is divided into cold extrusion sleeve, taper thread sleeve and straight thread sleeve.
Technical features of the sleeve:
1. It is suitable for the reinforcement connection construction in reinforced concrete structure of various structures bearing biaxial tensile and compressive forces.
2. Material saving, energy saving, not limited by steel composition and type.
3. It can be connected in all directions.
4. It can be made in advance, factory operation, no occupation of construction period, all-weather construction.
5. The operation is convenient and fast, and the construction speed is fast, which can greatly shorten the construction period.
Technical features of steel bar connecting sleeve:
1. The strength of sleeve joint of steel bar can meet the performance requirements of grade a joint in industry standard jgj107-96.
2. The thread profile of reinforcement connecting sleeve is good, with high precision and stable connection quality.
3. The application range of steel bar connecting sleeve is wide, which is suitable for the diameter of 16-40mm.
4. Grade II and grade III reinforcement shall be connected with the same diameter in any direction and position.
5. Adjustable type: the positive and negative thread type sleeve is suitable for connecting the steel bars at the places where the steel bars can not be rotated, such as the steel bar cage of the turning iron.
6. Fast construction speed: thread processing in advance of prefabrication and on-site processing, assembly construction.
7. Energy saving, pollution-free, safe and reliable construction.
The commonly used manual sleeve is made of chrome vanadium steel with the brand number of 50BV30, while the pneumatic sleeve is generally made of chromium molybdenum steel with the brand number of 35CrMo. Of course, 40ACr can also be made, with slightly poor rigidity.
Adopt international No.45 steel, special manufacturing technology,high dimensional precision and reliable quality.
It can be connected with HRB335 and HRB400 ribbed bars of Ф 16 - Ф 40mm.
It has been tested by the national construction quality supervision and inspection center and reached the grade I joint standard in jgj107-2003.
There are 52 varieties in three series of standard type, positive and negative screw thread type and different diameter type, which can meet the requirements of connecting steel bar with the same diameter, different diameter and adjustable length and direction in horizontal, vertical and oblique parts of building structure.
Classification by material:
1. Chromium molybdenum steel is an alloy of chromium (CR), molybdenum (MO), iron (FE) and carbon (c). It has good high-temperature processing performance, beautiful appearance after processing, can be deeply quenched, and has good impact absorption performance. Therefore, it is often used to manufacture pneumatic tools and large-scale manual tools in the industry.
2. Chromium vanadium steel is a kind of alloy tool steel with chromium vanadium alloy elements, which is mainly used in hand tools.
3. 45 carbon steel, namely 45 steel, with carbon content of about 0.45%, has become a commonly used processing material in steel due to its good processing performance and multi-directional processing technology. Among the above materials, Cr Mo steel is the best, and the sleeve is the best.
