Background technology
In traditional cast-in-place concrete structure, the connection of reinforcing bar, using overlap joint to connect, be welded to connect or squeeze more
The mechanical joining methods such as gland cylinder, the construction of bar connecting is complex and it is necessary to before cast concrete
Complete the connection of reinforcing bar, it is impossible to realize the connection of reinforcing bar between prefabricated component, thus cannot be carried out prefabricated construction.
In prior art, the bar connecting between assembly concrete architectural prefab needs to use sleeve grouting
Connect, in two connected reinforcing bars are inserted metal sleeve and in the space between sleeve and reinforcing bar, irrigate height
Performance cement mortar, cement mortar hardening after, mutual build-in between three thus realize the connection of reinforcing bar.Specially
Profit CN 103758291 B discloses a kind of shearing enhancement mode half grout sleeve, including sleeve body, described set
Cylinder is tubular structure, and the opening part that sleeve body is is provided with elastic rubber sealing ring, sleeve body other end
Opening part be provided with threaded connector, and be provided with grouting mouth on the sidewall of sleeve body end position
And grout outlet；Sidewall along sleeve body is provided with bolt hole, is provided with shearing bolt in described bolt hole.On
State sleeve and play, by increasing shearing bolt, the effect that shearing strengthens, but its structure is relative complex, make work
Skill also can complicate, and cost of manufacture can increase accordingly simultaneously.
In sum, need exploitation badly a kind of with low cost, it is possible to increase Grouted density, increase grouting material pair
The bond stress of reinforcing bar, the ability of the anti-shearing force of the joint portion being simultaneously effectively increased in sleeve and tensile strength
Grout sleeve.
Utility model content
The purpose of this utility model is to provide a kind of with low cost, it is possible to increase Grouted density, increases grouting
The material bond stress to reinforcing bar, ability and the tension of the anti-shearing force of the joint portion being simultaneously effectively increased in sleeve are strong
The grout sleeve of degree, and apply the prefabricated component having this grout sleeve.
Above-mentioned purpose is to be achieved through the following technical solutions: a kind of grout sleeve, including sleeve body, described
Sleeve body is provided with grouting mouth and air vent, the one end open of described sleeve body, and the other end is for connecting end；
The inwall of described sleeve body is provided with steel lobe, and the thickness of described steel lobe is inwardly tapered into by opening.So
Arrange, the inside of sleeve body can be made to divide and significantly increased, to ensure grouting material to connecting end by opening
In time connecting end flowing, there are enough flowing spaces, it is ensured that grouting material fills whole inner chamber, improve grouting closely knit
Degree, the thickness of grouting material increases simultaneously, is formed and strengthens district, increases the grouting material bond stress to reinforcing bar.It addition,
When, after grouting material molding, the interior intracavity of sleeve body is formed and inner chamber and the grout blanket of steel lobe mating shapes,
I.e. grout blanket is being more than the size of sleeve body opening near the size connecting end, adds the knot in sleeve
The ability of the anti-shearing force in conjunction portion and tensile strength, therefore the globality of binding site is more preferable.
The setting of steel lobe increases sleeve body integral rigidity, on the premise of meeting rigidity, can suitably subtract
Few sleeve body wall thickness, saves material.In the case of external diameter is identical, reduces wall thickness simultaneously, adds grouting
Material so that be in the milk more closely knit, reinforcing bar is higher with the adhesive property of sleeve body entirety.Additionally, pour into
Slurry forms the lock solid structure matched with sky in sleeve and steel lobe in sleeve body, and steel is greatly improved
The anchorage reliability of muscle.Should be appreciated that described steel lobe can be and sleeve body one-piece casting molding, it is possible to
It is cutting processing molding, it is also possible to be that work progress is arranged on intracavity in sleeve body, lives with sleeve body
It is dynamically connected.Certainly, steel lobe arrange position with grouting mouth and steam vent set by position not overlapping.
Further, the inwall of described sleeve body is provided with the steel lobe of more than two lobes.Steel lobe lobe number master is set
Depending on will be according to the size of sleeve, steel lobe can use the lobe number such as two lobes, three lobes so that the regulation of sleeve body
Space is bigger.
Further, it is less than the straight of reinforcing bar to be connected along the distance that the inner chamber of sleeve body is circumferential between described steel lobe
Footpath.It is arranged such, it is to avoid during construction reinforced bar docking, reinforcing bar inserts in the seam between steel lobe, it is achieved not right
Connect, strengthen difficulty of construction.
Further, the bottom of described sleeve body opening inner chamber is provided with annular protrusion.During grouting,
