Several methods of reinforced connecting connection sleeve straight thread connection sleeve is to be connected to the ends of the vertical steel ribs and transverse ribs with a rolling machine stripped part of the cutting method, then rolled directly into ordinary straight thread, with a special straight thread sleeve connected together to form reinforced the connection. Reinforcing steel bar rolling straight thread connection technology is the first technology invented at home and abroad, has reached the international advanced level; stripping rib rolling straight screw connection technology efficient, convenient and fast construction methods and energy consumption, improve efficiency, quality and reliable connection advantage by the majority of the construction units and owners of all ages. Straight screw connection technology of a new product. Reducing sleeve connection methods and procedures: (1) first connection sleeve is screwed into one end of the large-sized steel wire head and tighten. (2) The small size of reinforcement steel wire head screwed into the coupling sleeve, determined that the two bars in connection to the top of the sleeve after working with special rotating steel wrench or a pipe wrench. Connection quality control points: (1) first connection sleeve is screwed into one end of the large-sized steel wire head, and then the small size of reinforcement steel wire head is screwed into the coupling sleeve. (2) After completion of reinforced connecting thread connecting sleeve ends are exposed, and the number is equal, it is determined that the two bars in connection sleeve to find that a prerequisite for the top. Pros and cons of silk sleeve connection methods and procedures: (1) is connected to two bars moved two ports connecting sleeve, the sleeve so that the two steel rotary connector smoothly screwed into the coupling sleeve. (2) When the half steel wire head screwed connection sleeve, connection sleeve ends exposed observe not the number of steel wire head screwed thread. (3) to determine the connection at both ends of the sleeve and an equal number of exposed threads after working with a special wrench or a pipe wrench rotatably connected to the sleeve, so that connected two steel bars
