Features and functions of steel bar connection sleeve


The steel connection sleeve produced by our company Shanghai Hufeng Machinery Co., Ltd. has the advantages of high joint strength, fast connection speed, strong applicability, high construction efficiency, material saving, energy saving, and economy. The steel bar connection sleeve is suitable for various steel bar connection projects. The steel connection sleeves we produce have passed the inspection of the National Construction Engineering Quality Supervision and Inspection Center, and all items meet the standards. It is made of carbon structural steel with performance not lower than 45. Its mechanical properties and chemical composition meet the GB699 standard. The standard values of bearing capacity and tensile bearing capacity are 1.10 times greater than the corresponding bearing capacity standards of steel bars. The tensile strength of the joint made of the steel bar connecting sleeve is greater than the tensile strength of the steel bar base material, and greater than 0.9 times the measured value of the tensile strength of the steel bar base material. the
The thread matching accuracy is in accordance with GB197, the internal thread of the steel sleeve is 6H, the thread head thread is 7g, the surface roughness of the tooth profile is in accordance with the provisions of GB/T1031, the Ra value is 6.3um, and the Ra value of the rest of the processed parts is 12.5um . The surface has been treated with anti-embroidery, no rust, oil stains, cracks, black skin and other defects. Plastic protection plugs are added to the screw holes at both ends. the
The function of the steel bar connection sleeve:
Rib stripping and rolling straight thread connection of steel bar is to peel off a part of the longitudinal rib and transverse rib at the end of the steel bar to be connected by cutting, and then directly roll into ordinary straight thread, and connect it with a special straight thread sleeve to form Rebar connection. The rib stripping and rolling straight thread connection technology of steel bar is the first technological invention at home and abroad, reaching the international advanced level; the stripping rib rolling straight thread connection technology is efficient, convenient and fast construction method and energy saving and consumption reduction, improving efficiency, stable and reliable connection quality, etc. The advantages have been favored by the majority of construction units and owners. It is a new product of straight thread connection technology. the
Features of steel bar connection sleeve:
1. The use of our steel bar connection sleeve can greatly reduce the use of materials, and the operation is simple and not limited by the type of steel bar composition. the
2. The steel connection sleeve can be prefabricated in advance, which does not occupy the construction period and has high processing efficiency. the
3. The connection is convenient, fast and simple, no electricity is needed for construction, and it can be constructed all-weather regardless of the weather. the
4. It can connect horizontal, vertical and oblique HRB335, HRB400 steel bars of the same diameter or different diameters.
