Straight thread connecting device and method for reinforcing steel bars of fabricated structure
The invention provides a straight thread connecting device for reinforcing steel bars of a fabricated structure. The straight thread connecting device comprises a thread sleeve and a connecting sleeve; the connecting sleeve is provided with a first inner hole and a second inner hole; an inner thread of the thread sleeve is used for being screwed with an outer thread of a first reinforcing steel bar thread head to form a first thread pair; an inner thread of the first inner hole of the connecting sleeve is used for being screwed with an outer thread of a second reinforcing steel bar thread head to form a second thread pair; an inner thread of the second inner hole of the connecting sleeve is used for being screwed with an outer thread of the thread sleeve to form a third thread pair; the thread pitch of the first thread pair is not equal to that of the second thread pair; the thread pitch of the first thread pair is not equal to that of the third thread pair; and the thread pitch of the second thread pair is equal to that of the third thread pair. The invention further discloses a straight thread connecting method for the reinforcing steel bars of the fabricated structure. According to the straight thread connecting device and method for the reinforcing steel bars of the fabricated structure, under the conditions that the two reinforcing steel bars cannot move in the radial direction and the axial direction and cannot rotate, and deviation and dislocation exist in spiral lines of the threads of the two reinforcing steel bar thread heads, the two reinforcing steel bars can be reliably connected.
一种装配式结构钢筋直螺纹连接装置，包括螺套和连接套筒。连接套筒设有第一内孔和第二内孔，螺套的内螺纹用于与第一钢筋丝头的外螺纹相旋合形成第一螺纹副，连接套筒的第一内孔的内螺纹用于与第二钢筋丝头的外螺纹相旋合形成第二螺旋副，连接套筒的第二内孔的内螺纹用于与螺套的外螺纹相旋合形成第三螺纹副；其中，第一螺纹副与第二螺纹副的螺距不相等，第一螺纹副与第三螺纹副的螺距不相等，第二螺纹副与第三螺纹副的螺距相等。本发明还公开了装配式结构钢筋直螺纹连接方法。本发明能在两根钢筋不能沿径向和轴向移动、不能转动、且两根钢筋丝头螺纹的螺旋线存在偏差错位的情况下，实现两根钢筋之间的可靠连接。
