Description
Technical field
This utility model belongs to building engineering field, particularly relates to a kind of grout sleeve and prefabricated component.
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.As
Patent CN 105133795 A discloses a kind of reducing type half grout sleeve, uses seamless steel pipe as main body
Pipe, main body tube inwall is male and fomale(M&F), and main body tube upper end connects with the larger diameter end of conical tube, conical tube little
Diameter end connects with cylindrical tube one end.Above-mentioned sleeve adds a conical pipe and plays the effect of reducing, makes
Obtain this grout sleeve and be easily attached reinforcing bar, and make it deform so that it is be in close contact with being connected reinforcing bar through extruding.
But in above-mentioned grout sleeve, the setting of conical pipe makes the internal diameter of this part diminish suddenly, owing to reinforcing bar has one
Fixed rigidity, is difficult to so that reinforcing bar to be connected on the same line, even reinforcing bar to be extend into sleeve
The inside, existing defects in stress.
In sum, a kind of axially control being capable of reinforcing bar of exploitation and radial direction location are needed badly, it is ensured that reinforcing bar
And the positioning precision between grout sleeve, reasonable stress, can be effectively improved the grouting set of Grouted density simultaneously
Cylinder.
Utility model content
The purpose of this utility model is to provide a kind of axially control being capable of reinforcing bar and radially positions, it is ensured that
Positioning precision between reinforcing bar and grout sleeve, reasonable stress, the filling of Grouted density can be effectively improved simultaneously
Slurry sleeve, 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 internal diameter of described sleeve body is tapered into connecting end by opening, and the inwall of described sleeve body is provided with recessed
Groove, described groove is axially arranged along sleeve body inner chamber.During grout sleeve application, in the making of prefabricated component
During, grout sleeve is embedded in prefabricated component in advance, the connection end of sleeve body is connected with embedded bar, set
The opening of cylinder body connects outside prefabricated component, and when carrying out steel reinforcement abutting joints, reinforcing bar is from the opening of sleeve body
End stretches to sleeve body inner chamber, owing to the internal diameter of sleeve body is tapered into connecting end by opening, and steel
After muscle enters inner chamber, steel bar end moves to connection end under the constraint of sleeve body inwall, until reinforcing bar
End is connected with being connected end, and so, in the docking operation of reinforcing bar, sleeve body can realize essence to reinforcing bar
True axial control, it is achieved radially location, it is ensured that the positioning precision between reinforcing bar and grout sleeve, preferably feelings
Under condition, i.e. connect the central point of end on the centrage of the inner chamber of sleeve body time, can make to dock reinforcing bar and exist
On same straight line, reasonable mechanical；Reinforcing bar can be made to be positioned at the central part of inner chamber, so reinforcing bar after grouting simultaneously
The thickness of the grouting material of surrounding keeps consistent, improves Grouted density, increases the grouting material bond stress to reinforcing bar.
It is pointed out that to reach preferably technique effect, described sleeve body should at the internal diameter of air vent section
When the diameter slightly larger than reinforcing bar；It will be appreciated by those skilled in the art that air vent section described herein refers to
The length of interval that steam vent upwards takies in sleeve body lumen shaft.Inwall in sleeve body offers groove,
On the one hand taper into due to end radially connected in sleeve body, be unfavorable for that grouting material flows to connecting end,
Groove is set and can ensure that grouting material has enough flowing spaces, Grouted density can be effectively improved, on the other hand
The contact area between sleeve body and grouting material can be increased, to increase the gmatjpdumamics between itself and grouting material,
Make power transmission between reinforcing bar and sleeve body more uniform.
Further, the width of described groove is less than the diameter of reinforcing bar to be connected.It is arranged such, it is to avoid construction steel
During muscle docking, reinforcing bar inserts in groove, it is achieved not docking, strengthens difficulty of construction.
Further, the inwall of described sleeve body is provided with the groove of more than two.It is arranged such, can effectively increase
Add the contact area between sleeve body and grouting material, ensure that grouting material has enough flowing spaces as far as possible,
Improve Grouted density.
Further, it was provided with slurry hole between described groove or led stock tank.Cross slurry hole or lead stock tank a side is set
Face ensures that grouting material has enough flowing spaces in time connecting end flowing, enriches whole grout sleeve, simultaneously can
Grouting material in each groove is connected into entirety, increases the adhesion between sleeve body and grouting material, grouting
The globality of material is higher, and then is effectively increased the grouting material bond stress to reinforcing bar.
Further, the inwall of described sleeve body offers annular groove in air vent section.It is arranged such, can
Sleeve body is significantly increased, to ensure that grouting material has in time connecting endwall flow at the internal diameter of air vent section
Enough flowing spaces, it is ensured that grouting material fills whole inner chamber, improve Grouted density, and this part fills simultaneously
The thickness of slurry increases, and increases the grouting material bond stress to reinforcing bar, forms one section and strengthens district.It addition, when filling
After sizing material forming, the interior intracavity of sleeve body forms the grout blanket consistent with cavity shape, and i.e. grout blanket is at ring
Diameter at connected in star more than the diameter of sleeve body opening, adds the anti-shearing of joint portion in sleeve
The ability of power and tensile strength, therefore the globality of binding site is more preferable.
Further, at described annular groove, the interior radially connected end of inner chamber becomes larger.It is arranged such, can make
Obtain sleeve body radially connected end in air vent section to be gradually increased, be conducive to guiding grouting material to connecting end
Flow in portion, ensure enough flowing spaces simultaneously, improves Grouted density, the simultaneously thickness of this part grouting material
Degree increases, and increases the grouting material bond stress to reinforcing bar, forms one section and strengthens district.
Further, the intracavity bottom of described sleeve body opening is provided with annular protrusion.Due to sleeve body
