Steel straight threaded mechanical sleeve steel straight threaded mechanical sleeve 45, the adoption of international quality steel, special manufacturing process, high dimensional accuracy, reliable quality. It can be connected to the HRB335 16-40mm HRB400 grade level and ribbed bars. Steel straight threaded mechanical sleeve divided into standard, reverse threaded type, Reducing three series, more than 50 varieties, to meet the building structure of any part of the same diameter as horizontal, vertical, diagonal, etc., reducers you can adjust the length and direction of the steel connection needs. Features 1, high strength connection, the connection is stable and reliable quality. Joint strength to industry standards JGJ107-2003 "reinforced mechanical connection technology common point of order" in I class joint performance requirements. Joint tensile strength of not less than connected steel or reinforced actual tensile strength of 1.10 times the tensile strength of the standard value. 2, anti-fatigue properties. Joint by two million fatigue testing industry standards. 3, save material. 40mm diameter steel connecting sleeve, for example, extrusion sleeve quality 4kg, straight thread sleeve 1.1kg. Straight thread sleeve Quality is 25% extrusion sleeve and extrusion joints with joint performance was able to match. 4, construction convenient, fast connection speeds. Steel wire head processing factory job, do not take the construction period. Site connection assembly operations, take a short time. 5, simple processing steel wire head. Reinforced a loaded card to complete the stripping rib, thread rolling two processes, processing speed, high precision molded thread. 6, wide application. No welding requirements for steel, suitable for the diameter of 12 ~ 50mm HRB335, HRB400 rebar in any position with, Reducing connection. 7, environmental protection and construction. Steel wire head processing and joint site construction noise pollution, no fire, no smoke, safe and reliable. 8, saving energy. Device power is only 3 ~ 4kw, without dedicated distribution facilities, without erecting special wiring. 9, good resistance to low temperature performance. By -40oC low temperature. 10, reinforced connecting sleeve can be prefabricated in advance, does not account for the duration, high processing efficiency. Impact weather construction, from wind, rain, snow and other weather conditions.
