Definitions
- FIG. 11 is a view showing a three-rotation state after provisional coupling in the first embodiment.
- FIG. 13 is a view showing a reinforcing bar, a female screw body, and a male screw body.
- Fig. 14 is a view showing an embodiment of a female screw body in which parallel-taper integrated female screw portions are formed on both sides.
- the parallel screw is a screw in which the inner diameter to the outer diameter of the screw is constant along the axial direction, and the taper screw is formed so that the inner diameter to the outer diameter of the screw increases or decreases along the axial direction to form a taper angle. shape of the screw.
- the parallel-taper integrated screw coupling structure of the present invention includes a female screw body 20, a male screw body 30, a parallel-taper integrated female screw part 21, and a parallel-taper integrated male screw part 31 ) is included.
- the female threaded body 20 has a parallel female threaded part P1 and a tapered female threaded part T1 formed side by side with an inner diameter in the inward direction so that the tapered female threaded part T1 is positioned on the inner side of the parallel female threaded part P1. is formed
- the discontinuous portions 23 and 33 may have various shapes and methods as long as the threads are discontinuous.
- the threading is easy and there is no need to be concerned with the maximum inner diameter DT1 of the taper female thread part T1 or the maximum outer diameter DT2 of the taper external thread part P1 or the parallel male thread part (P1) or the parallel male thread part ( P2) can be formed in any diameter standard.
- the effective cross-sectional areas of the tapered screw portions T1 and T2 and the parallel screw portions P1 and P2 are added, thereby making it possible to have a tensile force or the like.
- the female screw body 20 and the male screw body 30 include coupling by the parallel screw parts P1 and P2, so that they can have straightness by the parallel screw parts P1 and P2, and have a tapered screw part (T1, T2). It is thought that the effect of straightness distortion is less effective than the coupling by the bay.
- the male screw body can be inserted into the female screw body and provisionally coupled without screw rotation.
- D2 the coupling depth D2 at the time of the provisional coupling can be increased (D2 > D1).
- the female threaded body 202 and the male threaded body 203 may be tentatively coupled such that the male and female taper screw portions are in contact 200 with each other and the male and female parallel screws are spaced apart 201 from each other. have.
- the screw thread is a single-row screw
- the male and female parallel threads start coupling when the male and female taper threads are made 0.5 turns.
- both the tapered screw part and the parallel screw part are in contact 300 and 301 when they are temporarily coupled, both the male and female tapered threads and the male and female parallel threads start to be coupled when rotating in the rotational direction.
- the female screw body 402 and the male screw body 403 are tentatively coupled so that the male and female tapered screw portions are spaced apart 400 from each other and the male and female parallel screw portions are in contact with each other (401).
- the three-line screw can be combined faster, but the loosening phenomenon becomes more severe.
- the parallel-taper screw structure secures a fast coupling speed as in the case of forming a multi-row screw, while reducing the lead angle of the screw with a single-row screw, resulting in loosening of the screw has the effect of minimizing
- the inner diameter of the parallel female screw part 45 is formed larger than the maximum outer diameter of 35.51 mm of the taper male screw part 42 (36.78 mm > 35.51 mm), when the male screw body 41 is inserted, the tapered male screw part 42 is parallel It does not interfere with the female thread part (45).
- phase difference between the thread end point of the taper female thread part 43 and the thread thread start point of the parallel female thread part 45 and the phase between the thread end point of the taper male thread part 42 and the thread start point of the parallel male thread part 44 Deviations may be formed corresponding to each other.
- a male screw body or a female screw body is integrated at one end of the reinforcing bar, a male screw body is integrated at both ends of the reinforcing bar, a female screw body is integrated at both ends of the reinforcing bar, or a male screw body and a female screw body are integrated at both ends of the rebar.
- the left end is formed as a right-hand end and the right end is formed as a left-hand end. Accordingly, it is possible to easily combine the reinforcing bars at both ends.
- the standard of the member integrated at both ends of the reinforcing bar is formed differently from each other, it is possible to have a different diameter joint. That is, when the male screw bodies are integrated at both ends of the reinforcing bar, the specifications of the male screw bodies at both ends are formed differently, or when the female screw bodies are integrated at both ends of the reinforcing bar, the specifications of the female screw bodies at both ends are formed mutually differently, or of the reinforcing bar When the male screw body and the female screw body are integrated at both ends, the specifications of the male screw body and the female screw body at both ends can be formed differently.
- a parallel-taper integrated male thread is formed on only one side of the reinforcing bar and a separate member is not joined to the other side, or a parallel-taper integrated female thread is formed on one side and a fixing member is formed on the other side, etc. configuration is possible.
- the female screw body 141 becomes a reinforcing bar coupler connecting the reinforcing bars that are the male screw bodies 142 from both sides.
- the parallel-taper integral male thread portion may be directly machined to the end of the reinforcing bar.
- the female screw body 141 may be provided with an anti-slip means for easy tool gripping in a predetermined section of the outer surface. That is, when the outer surface is splined by the anti-skid means, when the outer surface is knurled, when the cross-section is circular, when the cross-sectional shape is polygonal, and when one or more pairs of gripping surfaces are provided at opposing positions. By forming any one selected from among, the screw rotation and tightening operation of the female screw body 141 can be smoothly performed.
