It is equipped with filler rib 14 in double set port sleeves 10 and 20 inner cavity of single set port sleeve, the filler rib 14 includes circumferential Rib, axial rib and column type rib；Double set port sleeves 10 and single set 20 inner wall of port sleeve are arranged to corrugated structure； Separation rib 15 is equipped in the middle part of double 10 inner cavities of set port sleeve.

When it is implemented, circumferential rib in a manner of to be arranged in 20 inner cavity of double set port sleeves 10 and single set port sleeve, packet Include annular, interruption annular or spiral-shaped structure；Axial rib is arranged with axial manner in double set port sleeves 10 and single set port sleeve 20 inner cavities, including equal height type or tooth type structures；Column type rib by disperse it is uniformly distributed in a manner of be arranged in double set port sleeves 10 and single cover 20 inner cavity of port sleeve, including cylindrical or multi-edge column-shaped structure.Cement slurry can be enhanced by filler rib 14 and corrugated internal wall Bonding strength makes two reinforcing bars be connected with each other more secured.

When it is implemented, 15 crossbearer of separation rib is arranged in sleeve body inner cavity, two reinforcing bars can be made with identical length Degree is inserted in barrel bore, and cement slurry will not be interfered to be flowed in sleeve body inner cavity.

It is surrounded by filler baffle in exhaust feeding port 12, the extruding follower 30 is arranged to and exhaust 12 phase of feeding port Mating string configuration and its bottom surface is equipped with reinforcing ribs 34.

When it is implemented, filler baffle makes exhaust feeding port 12 protrude outward certain height from sleeve body, on the one hand Personnel are conveniently operated toward barrel bore filling concrete slurry, sleeve body is on the other hand enable to be packed into the water more than its cavity volume Material-mud when extruding follower 30 is squeezed from exhaust feeding port 12 toward inner cavity, can will be vented the cement slurry in feeding port 12 It is squeezed into barrel bore, air and extra slurry will outward be squeezed out from clout comb, make the cement of sleeve body inner cavity Slurry is more closely knit.

The middle part of follower 30 bottom surface is being squeezed when it is implemented, squeezing voussoir 31 and being arranged and from squeezing 30 bottom surface of follower It protrudes outward, reinforcing ribs 34 are arranged to the structure consistent with filler rib 14.

The fixed drainage conduit 32, which is mounted on, to be squeezed 30 end of follower and is equipped with cover plate bolt 320, in exhaust feeding port The screw socket gusset 120 to match with cover plate bolt 320 is equipped in 12.

When it is implemented, the fixed setting of drainage conduit 32 is squeezing 30 both ends of follower, it is both that sleeve will be discharged more than filler The pipeline of inner cavity, and be the bolt sleeve for squeezing follower 30 and being connect with sleeve body, cover plate bolt 320 passes through fixed drainage conduit 32 connect with screw socket gusset 120, will squeeze follower 30 and are firmly connected with sleeve body.

When it is implemented, 320 tail portion of cover plate bolt is equipped with blank flange, it is linked to be one with sleeve body when squeezing follower 30 It will the 32 nozzle closing of fixed drainage conduit when body.

When it is implemented, cover plate bolt 320 and screw socket gusset 120, which can also be arranged, is squeezing follower 30 and exhaust filler The other positions of mouth 12.

It is equipped with rotation tube socket 35 squeezing 30 both ends of follower, 35 bottom of rotation tube socket sets discharge gate, and inner wall is equipped with Cross bar swivelling chute, the activity drainage conduit 33 is sleeved in rotation tube socket 35 and its outer ring is equipped with retention bar 330, the positioning Cross bar 330 is fastened in cross bar swivelling chute, and the cross bar bayonet to match with retention bar 330 is equipped on exhaust feeding port 12 121。

When it is implemented, rotation tube socket 35 is arranged to corresponding round structure, discharge gate setting with activity drainage conduit 33 Non- shaft core position and break-through down in rotation tube socket 35 bottom, cross bar swivelling chute extend to the outside from rotation 35 inner wall of tube socket and from crowded The outside break-through in 30 side of follower, 33 bottom nozzle of activity drainage conduit is pressed to be arranged to the non-shaft core position consistent with discharge gate, It is designed with retention bar 330 in 33 both sides of activity drainage conduit, the setting of cross bar bayonet 121 is in filler baffle medium position and and cross bar Swivelling chute is corresponding.Retention bar 330 is fastened in limitation activity drainage conduit 33 in cross bar swivelling chute can only be in rotation tube socket 35 Rotary motion cannot be axially moved, and 33 bottom nozzle of activity drainage conduit is made to be faced with discharge gate, and at this moment barrel bore is extra Cement slurry can easily be discharged from discharge gate, 33 retention bar 330 of rotation activity drainage conduit will be rotated from cross bar Slot is caught in cross bar bayonet 121, will be squeezed follower 30 and is firmly connected with sleeve body, at this moment activity drainage conduit 33 is managed Mouth is in dislocation closed state with discharge gate, and the cement slurry of barrel bore cannot discharge.

The reinforcing bar socket 11 is arranged to the round structure to complement one another with positioning end cap 13, in reinforcing bar socket 11 4 Week is equipped with end cap bayonet 110, is equipped with buckle muscle gear 130 in 13 outer ring of positioning end cap, center wears mouth 131 equipped with reinforcing bar.

When it is implemented, being equipped with more vice card button muscle in 13 outer ring of positioning end cap keeps off 130, the length of buckle muscle gear 130 is more than Buckle muscle gear 130 is caught in after end cap bayonet 110 horizontal sliding again by the transverse width of end cap bayonet 110, and positioning end cap 13 will Firmly it is sleeved in reinforcing bar socket 11.

When it is implemented, the mode that positioning end cap 13 can also be connected through a screw thread is connect with reinforcing bar socket 11.

Double set port sleeves 10 and list set port sleeve 20 are equipped with more secondary positioning end caps 13, more secondary positioning end caps 13 The bore that reinforcing bar wears mouth 131 is different.

When it is implemented, larger intracavity space is arranged in sleeve body, a variety of steel of diameter in a certain range can be inserted in Muscle, such as the reinforcing bar of ten centimetres to 16 centimetres of diameter can be inserted in the same sleeve body, and reinforcing bar wears the bore of mouth 131 Match with bar diameter, make steel bar end can be inserted in sleeve body again will not double swerve, to limit reinforcing bar always It is in sleeve body shaft core position, straight line docking can be formed when two reinforcing bars are at sleeve body axle center.

, can be by various outer diameter specification when it is implemented, as long as double set port sleeves 10 replace the locating end plates of different bores Reinforcing bar carry out straight line docking, single port sleeve 20 that covers, can be by various outer diameter specification by replacing the locating end plates of different bores Reinforcing bar form straight line with the reinforcing bar of fixed specification and dock.

In conclusion the present embodiment solves, prior art reinforcing steel bar connecting sleeve tube is difficult to straight line connection reinforcing bar and slurry cannot The problem of filling sleeve provides a kind of combined steel reinforcement abutting joints sleeve that can replace the prior art.
