Preferably, the length of intermediate sleeve and the length ratio in Ribbed Bar insertion sleeve are 1.47.
The utility model compared with prior art, has the advantages that：
The half grouting attachment device provided by the utility model, realizes guiding role of the both ends cone cylinder inner wall to two reinforcing bars,
Two reinforcing bars of guarantee are coaxial docking, and are separately set by the reasonable spacing of circumferential salient rib, and radius is set, and both can guarantee that slurry
Be engaged after hardening with intermediate sleeve, and can guarantee that the slurry of perfusion sufficient amount in intermediate sleeve, meanwhile, semi-circular cross-section it is convex
Rise, stress concentration can be avoided, strengthen the shear resistance of attachment device, avoid sleeve that failure by shear occurs.
Measured by high stress tensile compression test and large deformation tensile compression test, during using the semi-circular cross-section circumferential direction salient rib,
Should grouting attachment device tensile strength be partly 635.6MPa, the strength enhancing 8% compared with traditional half grout sleeve.
Pass through the Ribbed Bar length ratio for reasonably designing intermediate sleeve with being inserted into from the second cone cylinder end, and intermediate sleeve
Internal diameter and the diameter of Ribbed Bar ratio reduce half grouting set, it can be achieved that while the groundwater increment of bond stress and slurry is ensured
Cylinder size.

Embodiment
The effect of to make to the architectural feature of the utility model and being reached, has a better understanding and awareness, to compared with
Good embodiment and attached drawing coordinate detailed description, are described as follows：
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of assembly of shear wall structure exterior wall reinforcing bar is partly in the milk attachment device, including centre
Sleeve 1, the first cone cylinder 2 for being co-axially located at 1 both ends of intermediate sleeve, the second cone cylinder 3.First cone cylinder 2, the second cone cylinder 3 and centre
1 integrally welded structure of sleeve.First cone cylinder 2, intermediate sleeve 1, the second cone cylinder 3 coaxially offer the through hole of perforation, and first
Cone cylinder 2, the through-hole diameter of the second cone cylinder 3 are less than the through-hole diameter of intermediate sleeve 1；First cone cylinder, 2 inner wall is equipped with internal thread, is used for
With carrying out screwing togather fixation with external screw thread reinforcing bar.1 inner wall of intermediate sleeve is equipped with multiple sections as semicircular circumferential salient rib 11,
Circumferential salient rib 11 smoothly transits at other positions with 1 inner wall of intermediate sleeve, is held with improving after slurry 4 hardens with intermediate sleeve 1
Wrap up in the shear resistance of power and device.Second cone cylinder, 3 inner wall is smooth surface, is inserted into easy to Ribbed Bar.
For the ease of making prefabricated panel, while the groundwater increment of bond stress and slurry 4 is ensured, half grouting set is reduced
The Ribbed Bar diameter ratio that 1 internal diameter of intermediate sleeve is connected with sleeve is arranged to 1.6~3.0, one by cylinder size, the present embodiment
As 2.28 be optimal；The length of intermediate sleeve 1 is arranged to 1.3~1.6 with the length ratio in Ribbed Bar insertion sleeve, generally
1.47 it is optimal；Adjacent circumferential salient rib 11 is set to 10~20mm, general 15mm is optimal；Circumferential salient rib 11

Half grouting attachment device of this assembly of shear wall structure exterior wall reinforcing bar is cast iron or cast steel, passes through mechanical milling
It is made, is tubular construction, cylinder middle part is cylinder type, and cylindrical inner is done circumferential salient rib 11 and designed, circumferential convex
It is semi-circular cross-section to play 11 section of rib, avoids the utility model from producing stress concentration when bearing excessive shear stress, and sleeve occurs
Failure by shear.Circumferential salient rib 11 is not only convenient for being engaged with intermediate sleeve 1 after grouting material 4 hardens, but also can strengthen connection dress
The shear resistance put, both ends are circular cone barrel structure, and internal thread processing is done in one end, and the other end does not process.The two of intermediate sleeve 1
End offers extravasating hole 12 and injected hole 13 respectively.The reinforcing bar being connected with internal thread taper cone barrel end does external screw thread processing, the other end
It is connected with Ribbed Bar, cone cylinder is equipped with rubber seal, mortar leakage prevention between the two with reinforcing bar.
In the process segment, an end bar and the first cone cylinder 2 first be attached or pre-installed, then with the bar construction of component
Other bar connectings are fixed, and 1 side wall of intermediate sleeve connects grouting, discharge pipe and guides to outside component template, then casting concrete, will
Connection reinforcing bar, intermediate sleeve 1 are embedded in component.In structure erection stage, precast shear wall connection has poured or another prefabricated
During component, after the connection reinforcing bar on component is inserted into the intermediate sleeve 1 of this prefabricated component, fixing component, from component side
Grouting mouth pours into grouting material 4 into intermediate sleeve 1, and grouting material 4 is after slurry mouth outflow, and component stands and hardened to slurry 4, and component connects
Construction is connect to terminate.
