The present invention has the advantages of no special process in site when used, convenient operation and simple use.
Description
(1) technical field
The reinforcing bar connector that the present invention relates in concrete structure, use.
(2) background technology
Existing reinforcing steel bar machinery connection includes: cold extrusion link technique, taper thread connection, straight thread connection etc.Though above-mentioned technology all has certain advantage separately, but, each leisure also exists the some shortcomings part in varying degrees, as sleeve cold extrusion link technique is with the high-pressure oil pump source that is used as power, by extruder branch sleeve is radially pushed, make the sleeve produce plastic strain,, form an integral body and transmit power with the mutual interlock of reinforcing bar.Because the equipment heaviness, labor strength is big, the bad easy generation oil leaking pollution reinforcing bar of corrective maintenance, and normal performance is renderd a service in influence, gives and uses maintenance to make troubles, and connection speed is not as being threaded; Taper threaded connection technique is with the taper thread die head threading machine steel bar end to be processed into taper thread earlier, then the sleeve of band taper thread is linked together with reinforcing bar to be docked.Certain screw-down torque must be applied when reinforcing bar is connected with sleeve and quality of connection could be guaranteed, if it is not tight that workman's inadvertent is twisted, easily produce slippage behind the reinforcing steel bar bear, the footpath is less than the parent material of reinforcement rebar base circle diameter (BCD) at the bottom of the taper thread, and strength of joint can be weakened, influence joint performance, though it is good to neutrality that taper thread connects, reinforcing bar is required tighter, reinforcing bar can not be crooked or horseshoe incision is arranged, otherwise it is incomplete easily to produce screw thread, stays hidden danger to quality of connection.Jumping-up straight thread link technique is earlier the shape of a hoof termination of reinforcing bar to be cut away, again with steel bar header with the steel bar end jumping-up, with the straight thread die head threading machine it is cut into straight thread, reinforcing bar that will be to be docked by straight screw sleeve links together.The jumping-up straight thread connects that not only operation is cumbersome, and the reinforcing bar head metallographic structure behind the jumping-up changes, and without temper, can produce stress and concentrate, and ductility reduces, and is disadvantageous to improving joint stressed.
(3) summary of the invention
The present invention has overcome above-mentioned reinforcing bar and has connected the operation inconvenience shortcoming that labor intensity is big, bonding strength is low, equipment cost is high that exists, and a kind of rebar connector of easy to operate, good connecting effect is provided.
For this reason, the present invention takes following technical scheme:
A kind of reinforcing bar connector comprises: first connector, be connected with first reinforcing bar, and the diameter of the first connector connecting reinforcement, one end forms first convex shoulder less than the diameter away from reinforcing bar one end; Second connector, be connected with second reinforcing bar, second connector is identical with the first connector structure, and the diameter of second connector connecting reinforcement one end forms second convex shoulder less than the diameter away from reinforcing bar one end, and first convex shoulder and the second convex shoulder end offset and arrange the formation protuberance; Be used for fastener that first connector is connected with second connector, described fastener cross section is curved, and described fastener intrados has deep-slotted chip breaker, and described deep-slotted chip breaker cooperates with described protuberance, and the groove angle of described deep-slotted chip breaker is less than 8.5 degree; Be used to the sleeve that prevents that fastener from coming off, described sleeve lower end is uncovered, is socketed on the described fastener.
Further, described fastener can be 2 or 4, and symmetric arrangement is buckled in protuberance.
The end of the uncovered side of the corresponding sleeve of described fastener is provided with the boss of extension, and the external diameter of described boss is greater than the external diameter of described sleeve.
Described connector and reinforcing bar welding are fixing.
Described sleeve is welded by sleeve end cap and two half-cylindrical sleeve wall.
Employing the present invention have the following advantages: only needs before using connector and reinforcing bar to be welded, do not have special processing during use at the scene in factory, and easy to operate, use simple; With low cost, result of use is good; Environmental suitability is strong, and connected mode is simple and reliable, but accelerating construction progress reduces construction costs, and its integrated cost is low.

(5) specific embodiment
As shown in Figure 1, a kind of reinforcing bar connector comprises: first connector 1, be connected with first reinforcing bar 2, and the diameter of the first connector connecting reinforcement, one end forms first convex shoulder 3 less than the diameter away from reinforcing bar one end; Second connector 4, be connected with second reinforcing bar 5, second connector is identical with the first connector structure, and the diameter of second connector connecting reinforcement one end forms second convex shoulder, 6, the first convex shoulders and the second convex shoulder end less than the diameter away from reinforcing bar one end and offsets and arrange and form protuberance 7; Be used for fastener 8 that first connector is connected with second connector, described fastener cross section is curved, and described fastener intrados has deep-slotted chip breaker, and described deep-slotted chip breaker cooperates with described protuberance 7, and the groove angle of described deep-slotted chip breaker is less than 8.5 degree; Be used to the sleeve that prevents that fastener from coming off, described sleeve is welded by sleeve end cap 10 and two half-cylindrical sleeve wall 11.Worn-out mouthful of described sleeve lower end is socketed on the described fastener.The end of the uncovered side of the corresponding sleeve of described fastener is provided with the boss 9 of extension, and the external diameter of described boss is greater than the external diameter of described sleeve.Described fastener is 2, and symmetric arrangement is buckled in protuberance.Described connector and reinforcing bar welding are fixing.
During operation, to be connected reinforcing bar 2,5 and carry out factory's welding with connector 1,4 respectively, by fastener 8 first connector and second connector are located, behind the one the second connectors location, sleeve end cap 10 integral body are enclosed within the outside of fastener 8, then that two sleeve wall 11 are fixing with 10 welding of sleeve end cap, this structure is utilized the circumferential location of the gravity realization of self to integral body, thereby guarantees the axiality of two connectors.Outside fluid concrete after whole packaging, thus realize connection easily to reinforcing bar.When being connected reinforcing bar and bearing pulling force, between fastener and connector, produce locking phenomenon, thereby make and produce less displacement between two connectors, guarantee that the axial load that jointing bears reaches design load.
