      鋼筋直螺紋連接屬于機械連接一種方法,直螺紋還劃分下面三種方式。
      The straight thread connection of reinforcement belongs to one method of mechanical connection. The straight thread is also divided into the following three methods.
      ⑴ 鐓粗直螺紋連接:是把鋼筋端頭鐓粗后制作的直螺紋和連接件螺紋咬合形成的接頭再切削成型,鐓頭質量較難控制。
      (1) upsetting straight thread connection: it is the joint formed by the engagement of the straight thread made after upsetting the end of the steel bar and the thread of the connecting piece. The quality of the upsetting head is difficult to control.
      ⑵ 直接滾壓直螺紋連接:是把帶肋鋼筋放進滾壓機通過滾絲輪滾壓成型,螺紋精度稍差,存在虛假螺紋現象。
      (2) direct rolling straight thread connection: it is to put the ribbed steel bar into the rolling machine and roll it through the rolling wheel to form, with slightly poor thread accuracy and false thread.
      ⑶ 剝肋滾壓直螺紋連接:是先將鋼筋接頭縱、橫肋剝切處理,使鋼筋滾絲前的柱體直徑達到同一尺寸,然后滾壓成型。它集剝肋、滾壓于一體,成型螺紋精度高,滾絲輪壽命長,是目前直螺紋套筒連接的主流技術。
      (3) rib stripping and rolling straight thread connection: firstly, strip and cut the longitudinal and transverse ribs of the reinforcement joint to make the column diameter reach the same size before the reinforcement rolling, and then roll forming. It integrates rib stripping and rolling, with high precision of forming thread and long service life of thread rolling wheel. It is the mainstream technology of straight thread sleeve connection at present.
