Description
【Technical field】
The present invention relates to a kind of bar connecting grout sleeve.
【Background technology】
Cast form being used the grout sleeve that prior art is used, the inwall of the grout sleeve for being used forms the inner chamber of correlation more
The tension and resistance to compression, shear resistance of structures shape sleeve, barrel bore structure have to the confinement mechanism and Strain Distribution of sleeve
Significantly affect, sleeve Strain Distribution is corresponding with inner-cavity structure, different rules are shown in smooth section and deformation section；Sleeve is to filling
The vertical force component of the constraint of slurry mutual extruding force at inwall convex hole rib, constraint of the smooth section to grouting material is depended on
In the size of grouting material splitting deformation.Therefore, the fin of multiple tracks is processed in sleeve lining in design plus man-hour requirement, half is in the milk
Sleeve must also be produced and be molded for sleeve processes an excessive silk lap joint of connection when processing using ductile cast iron material, by
Need to be formulated in the material of spheroidal graphite cast-iron, when material quality is unstable, it is necessary to adjust the mechanics that formula meets product
Performance requirement, before production formula adjustment process it is more long, although production technology cost is relatively low, but ductile cast iron material price compared with
Expensive, in the grout sleeve of Large-size rebar, product material is more, price, and economy is bad.
Disadvantages described above, is worth improving.
【The content of the invention】
In order to overcome the shortcomings of existing technology, the invention provides a kind of bar connecting grout sleeve.
Technical solution of the present invention is as described below：A kind of bar connecting grout sleeve, including sleeve body, the sleeve sheet
Body one end is provided with grouting mouth, and the other end is provided with grout outlet, it is characterised in that the sleeve body is made up of seamless steel pipe,
And two or more rifling is provided with the inwall of the sleeve body.
According to the present invention of said structure, it is characterised in that formed on the sleeve body inwall projection land and
Recessed groove, the spacing between the adjacent land is equal.
According to the present invention of said structure, it is characterised in that the two ends of the sleeve body are provided with sealing ring, form complete
Grout sleeve.
According to the present invention of said structure, it is characterised in that the sealing ring is elastic rubber sealing ring.
According to the present invention of said structure, it is characterised in that one end of the sleeve body is provided with bar connecting portion, shape
Into half grout sleeve.
According to the present invention of said structure, it is characterised in that the bar connecting portion is necking end, and the necking end
Screw thread is provided with inwall.
According to the present invention of said structure, it is characterised in that the bar connecting portion is steel pipe extension body, the steel pipe prolongs
The length of body long is the 1/2 of the length of the sleeve body.
According to the present invention of said structure, it is characterised in that the steel pipe extension body is by extruding and bar connecting.
According to the present invention of said structure, its advantage is that the present invention, as raw material, is passed through using seamless steel pipe
Thorax bed processing forms two or more rifling on steel pipe inner wall, and the land and recessed the moon of projection are formed on inwall
Rifling, the spacing between adjacent land is equal, and the tension of sleeve, shearing resistance and anti-pressure ability are good, and requires system according to different
Help grout sleeve or the grout sleeve of screw thread half, the grout sleeve of cold extrusion half, simple structure, convenient processing and manufacture, it is to avoid
The production of existing grout sleeve wastes high, pollutes the shortcoming of big and high cost.
