Description
Technical field
The utility model is related to prefabricated components connection areas, are more particularly to a kind of grout sleeve connection knot of manual exhaust
Structure.
Background technology
It is poured in the prior art in building reinforced concrete, by the integrated side of being mainly the following of two bar connectings
Formula：The mutual welding of reinforcing bar, casing press joining method, bending binding method.The construction of above-mentioned several connection types is complex, and
And bar connecting must be completed before casting concrete, it is not suitable for the assembly construction of precast concrete.And in prefabricated
In the construction of reinforced concrete structure, a kind of reinforcing steel bar connecting sleeve tube of generally use is attached.The connection type principle is substantially such as
Under：Through the hollow type reinforcing steel bar connecting sleeve tube of casting, reinforcing bar penetrates sleeve inner from both ends open, need not overlap or fuse,
The structural mortar of high intensity microdilatancy is filled between reinforcing bar and sleeve, that is, completes steel bar joining action.The mechanism that it is connected is main
It is acted on by the confinement of sleeve with mortar, in addition itself has microdilatancy characteristic, thereby between enhancing and reinforcing bar, sleeve inside
Positive acting power, reinforcing bar is the frictional force by the positive force and rough surface generation, to transmit reinforcement stresses.Grout sleeve connects
Binding structure bonding strength is good and easy to operate, is used widely in prefabricated reinforced concrete structure.
But in above-mentioned sleeve connection mode, it is positioned at the mode of the top of overfolw hole, grouting in generally use grout hole
The structural mortar of high intensity microdilatancy is poured into from the grout hole of its side wall, mortar fills the gap that tube wall and reinforcing bar are formed, and
It is flowed out under gravity from overfolw hole.So slurry will not generally be poured by being located at grout hole superjacent air space in sleeve cavity
Liquid reduces bonding strength, and in filling process, and tube wall and reinforcing bar are formed by between gap, especially two reinforcing bar ends
Certain proportion is had in the gap of head and hole occurs, and the bonding strength of reinforcing bar is caused to reduce.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of manual exhaust for the bonding strength that can improve reinforcing bar
Grout sleeve connection structure.
To achieve the above object, the utility model provides following technical solution：A kind of grout sleeve company of manual exhaust
Binding structure, including grout sleeve ontology, grout sleeve ontology are equipped with slurry-feeding hole and slurry outlet, and the slurry-feeding hole is in slurry outlet
The opening section of lower section, the slurry outlet is more than entrance section, and the opening of the pulp casing, which is equipped with, blocks pulp casing
Ball sealer, the slurry outlet is connected with pulp casing, and the inner wall of one end of the pulp casing is equipped with internal thread, the pulp
One end of casing is equipped with the stud with screw-internal thread fit, and the one side away from ball sealer of the stud, which is equipped with, stretches out pulp casing
One end of connecting rod, the connecting rod is equipped with handle, and spring, the pulp casing lower section are equipped between the stud and ball sealer
Circumferential side wall be equipped with discharge port, the slurry-feeding hole be connected with into slurry casing, it is described into slurry casing be equipped with for measure into
Starch the first pressure sensor of pressure.
The further spring overcoat is equipped with telescopic rod.
On the further stud second pressure sensor, the first pressure sensing are equipped with towards one end of ball sealer
Device and second pressure sensor are respectively connected with external display.
The circumferential side wall of the lower section of the further pulp casing is tapered and discharge port is located at the lowest point of taper.
The slurry in grout sleeve is squeezed from the bottom up in conclusion the utility model can recycle, gas is bit by bit
It excludes, when what the discharge port below pulp casing was discharged is slurry, has indicated the intrinsic slurry of grout sleeve
The no bubble being extruded and the space for filling with grout sleeve ontology, to improve the bonding strength of reinforcing bar.

Specific implementation mode
A kind of embodiment of the grout sleeve connection structure of manual exhaust of the utility model is made furtherly referring to Fig.1
It is bright.
A kind of grout sleeve connection structure of manual exhaust, including grout sleeve ontology 1, grout sleeve ontology 1 are equipped with
Slurry-feeding hole 2 and slurry outlet 9, the slurry-feeding hole 2 are cut in the lower section of slurry outlet 9, the opening section of the slurry outlet 9 more than entrance
Face, the opening of the pulp casing 10 are equipped with the ball sealer 8 for blocking pulp casing 10, and the slurry outlet 9 is connected with pulp
The inner wall of casing 10, one end of the pulp casing 10 is equipped with internal thread, and one end of the pulp casing 10 is equipped with and internal thread
The stud 13 of cooperation, the one side away from ball sealer 8 of the stud 13 are equipped with the connecting rod 6 for stretching out pulp casing 10, the company
One end of extension bar 6 is equipped with handle 14, and spring 12 is equipped between the stud 13 and ball sealer 8,10 lower section of the pulp casing
