Description
Technical field
This utility model is related to a kind of assembled grout sleeve, belongs to construction engineering technical field.
Background technology
In traditional cast-in-place concrete structure, connect, be welded to connect or extruded sleeve using overlap joint more than the connection of reinforcing bar
The mechanical connection manners such as cylinder, the construction of bar connecting are complex and it is necessary to the connection of reinforcing bar is completed before casting concrete.
In prior art, the connection between reinforcing bar needs to be attached using sleeve grouting, by two connected reinforcing bars
High-performance water cement mortar is irrigated in insertion metal sleeve and into the space between sleeve and reinforcing bar, after cement mortar hardening, three
Between person, mutual build-in is so as to realizing the connection of reinforcing bar.But, the sleeve in existing market, because its hole size is longer and structure
Shape is special, brings many difficulties to processing and manufacturing, has that production cost is higher, the low shortcoming of working (machining) efficiency, and existing
Its section of grout sleeve is combined with grouting material, and formed lifting surface area is less, and safety stock is not high enough, unstable properties.
In sum, need badly exploitation one kind can processing and manufacturing easily, it is low production cost, high in machining efficiency and combine and receive
Power area bigger, safety stock is higher, more reliable performance grout sleeve.
Utility model content
For deficiencies of the prior art, the utility model proposes a kind of assembled grout sleeve, by band
There is the threaded coupling sleeve end cap of straight thread and be in the milk end sleeve to solve the problems, such as to propose in above-mentioned background technology and defect.
This utility model lifting surface area is bigger, and safety stock is higher, more reliable performance, and handling ease, low cost of manufacture.
To achieve these goals, this utility model is by the following technical solutions realizing：
A kind of assembled grout sleeve, including metal sleeve body, it is characterised in that：The metal sleeve body includes spiral shell
Stricture of vagina branch sleeve end cap and grouting end sleeve, the threaded coupling sleeve end cap central are provided with connecting hole, and connecting hole inwall sets
There is the outer straight screw connection of interior straight thread, the interior straight thread and the first end reinforced setting；The threaded coupling sleeve end cap
Including integrally formed end cap portions and sleeve connection portion, sleeve connection portion outer wall is provided with straight thread；Grouting end sleeve one
The slurry that is respectively arranged at two ends with of side pours into mouth and a slurry overfall, and grouting end sleeve lining is provided with straight thread, fills
Slurry end sleeve one end is connected with the external screw thread in sleeve connection portion by straight thread；The grouting end sleeve inner center is inserted with second
Reinforcing bar, and the second reinforcing bar stretches out the grouting end sleeve other end, first reinforcing bar, the axis of the second reinforcing bar are covered with grouting end
The axis of cylinder is on same straight line；Grouting material is perfused between second reinforcing bar and grouting end sleeve inner.
Further, the external screw thread of sleeve connection portion outer wall is outer straight thread.
Further, the grouting end sleeve outer diameter size is identical with end cap portions outside dimension.
Further, the slurry pours into mouth and slurry overfall diameter is identical.
Further, the form of thread section of the straight thread is triangle, rectangle, trapezoidal, zigzag.
Further, the straight thread is single line or multi-thread.
Further, grouting end sleeve is made using seamless steel pipe.
The beneficial effects of the utility model：Grout sleeve of the present utility model is compared with existing product in market, its filling
Slurry end form of sleeve is combined with grouting material by the section of form of thread, the stress surface for being formed using internal straight thread form
Product is bigger, and safety stock is higher, more reliable performance；Meanwhile, grouting end of the present utility model sleeve can directly be added using seamless pipe
Work, female thread adopt forming taps tapping, handling ease, low cost of manufacture.
