The length of described external screw thread (4) is about 3/4 ~ 1 of hollow shaft 1 total length.
The utility model compared with prior art, has the following advantages and beneficial effect:
(1) this connector improves existing sleeve, and the outer surface of sleeve arranges the rib tooth of protrusion, and as the impetus of instrument, construction tool can not skid, and improves operating efficiency.
(2) after it solidifies in building building cement, the phenomenon that when the rib tooth that its outer surface is provided with also can help effectively to avoid building external shock, sleeve skids, safe and reliable.
(3) applied range, is not subject to the restriction of reinforcing bar composition and kind, can be connected in any direction reinforcing bar with the same reducing of position, can to not rotating place's bar connecting.
(4) easy to operate, quick, speed of application is fast, can reduction of erection time greatly.
(5) can comprehensively connect, quality of connection is reliable and stable.
(6) can be prefabricated in advance, factory operation, does not take the duration, all-weather construction.

Detailed description of the invention
According to drawings and embodiments the utility model is described in further detail below, but embodiment of the present utility model is not limited thereto.
As shown in Fig. 1 ~ 5, rebar connector of the present utility model, comprises hollow shaft 1, sleeve 2.The total length of sleeve 2 is about 2/3 ~ 1 of hollow shaft 1 total length, is preferably 3/4 ~ 5/6.The inner surface of described hollow shaft 1 is provided with internal thread 3, the two ends that can make to be connected reinforcing bar tightly be fixed on connector; One end of described hollow shaft 1 is provided with 3 ~ 8 openings 5 vertically uniformly, 5 ~ 8 openings 5 are preferably set, the setting of opening 5 can make to be connected reinforcing bar 9 and enter easily, and the length of opening 5 is about 1/3 ~ 2/3 of hollow shaft 1 total length, is preferably 1/2 ~ 2/3; The outer surface of described hollow shaft 1 is provided with external screw thread 4 near one end of opening 5.The length of external screw thread 4 is about 3/4 ~ 1 of hollow shaft 1 total length, is preferably 4/5 ~ 6/7.The endoporus of described sleeve 2 near hollow shaft 1 one end is provided with chamfering buckle 6, its role is to sleeve 2 is enclosed within hollow shaft 1 under the effect of the pressure more smoothly, and engage with the external screw thread 4 in hollow shaft 1, thus sleeve 2 is made better to be fixed in hollow shaft 1; The outer surface of described sleeve 2 is provided with uniformly 3 ~ 5 rib teeth 7 protruded, 3 ~ 4 rib teeth 7 protruded preferably are set, its role is to can as the impetus of instrument, construction tool can not skid, the adhesive force between connector and concrete can also be made simultaneously, improve tensile strength, strengthen stability; The inner surface of described sleeve 2 have passed through roughening process.Wherein, arrange and greatly can improve hollow shaft 1 and the frictional force of sleeve 2 through the inner surface 8 of roughening process and external screw thread 4, chamfering buckle 6 is set simultaneously again, can prevents sleeve 2 from coming off, improve stability and security.
When using described rebar connector, first one end mantle fiber being connected reinforcing bar 9 is screwed into hollow shaft 1 one end away from opening 5, again another is connected reinforcing bar 9 and puts the sleeve 2 of described rebar connector and the one end this being connected reinforcing bar 9 is injected hollow shaft 1 and had one end of opening 5, one end and the hollow shaft 1 sleeve 2 with chamfering buckle 6 have on the end thereof contacts of opening 5.By the extruding of the instrument such as pipe wrench, beat sleeve 2, hollow shaft 1 is had, and one end of opening 5 is squeezed compresses into sleeve 2.Because hollow shaft inner surface is provided with internal thread 3, tightly can clamp and be connected reinforcing bar 9; Simultaneously, the outer surface of hollow shaft 1 is provided with external screw thread 4, the inner surface of sleeve 2 have passed through roughening process, frictional force increases, and on sleeve 2, be also provided with chamfering buckle can engage with external screw thread 4, can better prevent sleeve 2 from coming off, when the sleeve 2 of rebar connector is enclosed within after in hollow shaft 1 completely, sleeve 2 is connected more firm with hollow shaft 1.
As mentioned above, just the utility model can be realized preferably.
