For solving the problem, the technical scheme that the utility model universal building complete thread reinforcing steel bar adopts is: comprise reinforcing bar body and the spiral fin being positioned at described reinforcing bar body radial outside, described spiral fin extends to the axial end portion of described reinforcing bar body.
Its additional technical feature is:
The cross section of described spiral fin is isosceles trapezoid;
Described spiral fin top is with certain chamfering;
The spiral fin being positioned at described reinforcing bar body diameter two ends by through these diameter two ends and vertical with this diameter two parallel planes cut;
The helical angle of described spiral fin is 15---75 degree;
The helical angle of described spiral fin is 30---45 degree.
Second technical problem to be solved in the utility model is just to provide a kind of special connector of above-mentioned universal building complete thread reinforcing steel bar.
For solving the problem, the technical scheme that the special connector of the utility model universal building complete thread reinforcing steel bar adopts is: comprise connection pipe body, be provided with the internal thread that described spiral fin matches inside described connection pipe body.
Its additional technical feature is:
Spanner draw-in groove or fixture block is had in described connection pipe body arranged outside;
The cut axially consistent with described connection pipe body is had in described connection pipe body arranged outside.
Universal building complete thread reinforcing steel bar provided by the utility model and special connector are compared with prior art, have the following advantages: one, comprise reinforcing bar body due to universal building complete thread reinforcing steel bar and be positioned at the spiral fin of described reinforcing bar body radial outside, described spiral fin extends to the axial end portion of described reinforcing bar body, special connector comprises connection pipe body, the internal thread that described spiral fin matches is provided with inside described connection pipe body, during construction, only connection pipe body need be enclosed within reinforcing bar body one end, then body is rotationally connected, reinforcing bar body is spilt from connection pipe body end, then by the end part aligning of adjacent reinforcing bar body and this reinforcing bar body, rotate backward connection pipe body, adjacent reinforcing bar body is screwed in connection pipe body, when the length that adjacent two reinforcing bar bodies insert connection pipe body is roughly equal, as long as now the diameter of reinforcing bar body and the width of spiral fin and highly and the intensity of connection pipe body meet the requirements, the bonding strength of adjacent reinforcing bar body just can be secure, and easy construction, the reinforcing bar of random length arbitrarily intercepts, its two, the cross section due to described spiral fin is isosceles trapezoid, described spiral fin top is with certain chamfering, tensile strength is stronger, they are three years old, due to the spiral fin that is positioned at described reinforcing bar body diameter two ends by through these diameter two ends and vertical with this diameter two parallel planes cut, like this, whole reinforcing bar is combined more firm with the concrete of surrounding, avoid between reinforcing bar and surrounding concrete and rotate, improve reinforcing bar and the concrete bond strength of periphery, its four, the helical angle due to described spiral fin is 15---75 degree, the helical angle of described spiral fin is preferably 30---45 degree, make reinforcing bar body and splicing sleeve bonding strength stronger.
Owing to having spanner draw-in groove or fixture block in described connection pipe body arranged outside or having the cut axially consistent with described connection pipe body in described connection pipe body arranged outside, convenient when making to screw splicing sleeve, and after concreting, avoid splicing sleeve to rotate relative to the concrete of its periphery, further enhancing splicing sleeve and concrete bonding strength.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the structure of the utility model universal building complete thread reinforcing steel bar and use principle are described in further details.
As depicted in figs. 1 and 2, the structural representation of the utility model universal building complete thread reinforcing steel bar, the utility model universal building complete thread reinforcing steel bar comprises reinforcing bar body 1 and is positioned at the spiral fin 2 of reinforcing bar body 1 radial outside, and spiral fin 2 extends to the axial end portion of reinforcing bar body 1.As shown in Figure 3, the structural representation of special connector, special connector comprises connection pipe body 4, is provided with the internal thread 5 that spiral fin 2 matches inside connection pipe body 4.During construction, only connection pipe body need be enclosed within one end of reinforcing bar body 1, then body is rotationally connected, reinforcing bar body 1 is spilt from connection pipe body end, then by the end part aligning of adjacent reinforcing bar body 1 with this reinforcing bar body 1, rotate backward connection pipe body, adjacent reinforcing bar body is screwed in connection pipe body, when the length that adjacent two reinforcing bar bodies insert connection pipe body is roughly equal, as long as now the diameter of reinforcing bar body and the width of spiral fin and highly and the intensity of connection pipe body meet the requirements, the bonding strength of adjacent reinforcing bar body just can be secure, and easy construction, the reinforcing bar of random length arbitrarily intercepts.
The cross section of spiral fin 2 is isosceles trapezoid, preferably on spiral prominence rib top with certain chamfering, tensile strength is stronger.
The spiral fin 2 being positioned at reinforcing bar body 1 one diameter two ends by through these diameter two ends and vertical with this diameter two parallel planes cut, side grain 3 is formed in the axial both sides of reinforcing bar body 1, like this, whole reinforcing bar is combined more firm with the concrete of surrounding, avoid between reinforcing bar and surrounding concrete and rotate, improve reinforcing bar and the concrete bond strength of periphery.
The helical angle of spiral fin is 15---75 degree; The helical angle of spiral fin is preferably 30---45 degree, make reinforcing bar body and splicing sleeve bonding strength stronger.
As shown in Figure 4, there is spanner draw-in groove 7 in connection pipe body 4 arranged outside, or as shown in Figure 5, have fixture block 6 in the arranged outside of connection pipe body 4, like this, spanner can be adopted to be rotatably connected body 4.More convenient to operate, and after concreting, avoid splicing sleeve 4 and rotate relative to the concrete of its periphery, further enhancing splicing sleeve and concrete bonding strength.
As shown in Figure 4 and Figure 5, the arranged outside of connection pipe body 4 has at the cut 8 axially consistent with connection pipe body 4, convenient when making to screw splicing sleeve, same after concreting, avoid splicing sleeve 4 to rotate relative to the concrete of its periphery, further enhancing splicing sleeve and concrete bonding strength.
Protection domain of the present utility model is not only confined to above-described embodiment, if structure and the utility model universal building complete thread reinforcing steel bar structure same or similar, just drop on the utility model protection scope.
