Abstract
It the utility model is related to concrete prefabricated element connection construction technical field, more particularly to a kind of be threadedly coupled connects compound reinforcing steel bar connecting sleeve tube with grouting, the grout sleeve of polygon prism structure half of the present utility model, sleeve grouting linkage section can be made to be tightened with convenient use common wrench during bar connecting, operating efficiency is improved, ensures threaded connection quality.The technical scheme is especially suitable for half grout sleeve using casting technique manufacture.
Description
Technical field
It the utility model is related to concrete prefabricated element connection construction technical field, more particularly to a kind of threaded connection and filling
Slurry connects compound reinforcing steel bar connecting sleeve tube, is one kind of half grout sleeve.
Background technology
Industrialized building is the main direction of development of China's future architecture industry, modern prefabricated concrete structure construction
In, the steel bar stress of prefabricated components is mainly using sleeve grouting connection method connection, therefore grout sleeve is in fabricated construction
One of important supplementary material.Sleeve grouting reinforcement joint by branch sleeve, ungauged regions high-strength cement mortar (or cement base fill
Slurry) and sleeve both ends connection Ribbed Bar formed, its principle is：Ungauged regions high strength cement mortar is passed through into Grouting Pipe
Pour into branch sleeve, the full gap between sleeve and reinforcing bar of filling, the high-strength mortar and reinforcing bar set formed after cement mortar hardening
Cylinder inwall is combined closely, and by two bar connectings together.
The grout sleeve of early stage is full grout sleeve, i.e., both ends are using the sleeve of grouting way connection reinforcing bar.In recent years
There is a kind of half grout sleeve that traditional mechanical joining methods are connected to Application of composite with grouting, one end of sleeve is using machinery
Connection, is mainly threadedly coupled, and holds axis to be machined with internal thread hole herein, when making prefabricated components, by the one of reinforcing bar to be connected
End processes matched screw thread.Reinforcing bar is tightened with sleeve and linked together, by positioning, colligation, cast concrete, is formed
Prefabricated components.When component is installed, the reinforcing bar reserved on another component is inserted in above-mentioned sleeve, injects grouting material, by reinforcing bar with
Sleeve anchor connection together, so as to realize the connection between component.Compared with full grout sleeve, half grout sleeve saves former material
Material, cost is relatively low, and quality of connection is easily guaranteed that, thus application is more and more extensive.Half current grout sleeve profile is main still
Cylinder or cone shape are used with reference to full grout sleeve.Threaded connection one end is when reinforcing bar and sleeve group connect, it is necessary to using pipe wrench,
It is very inconvenient, it is also bad to control the torque tightened.
Utility model content
The technical problems to be solved in the utility model is：When being connect for half grout sleeve grouting linkage section reinforcing bar with sleeve group
The problem of tightening inconvenience, the utility model provide a kind of grout sleeve of polygon prism structure half.
Technical scheme is used by the utility model solves its technical problem：A kind of grout sleeve of polygon prism structure half,
Including sleeve body, described sleeve body one end is threaded connection section, and the other end is grouting linkage section, is provided with sleeve body
It is in the milk mouth and thick liquid discharge mouth, respectively close to the both ends of grouting linkage section, the threaded connection section has for the grouting mouth and thick liquid discharge mouth
Internal thread, at least there are two planes on the outer wall of threaded connection section.
Fix and clamp for the ease of spanner, the outer wall of the grouting linkage section is shaped as equilateral polygon prism structure.
The side number of the equilateral polygon prism structure is even number.Such opposite face is parallel, and common wrench easy to use is tightened.
Preferably, the polygonal prism in Shuo Weiliu.
Further, preferably, opposite side takes national standard nut opposite side size apart from size on the premise of intensity requirement is met.
The beneficial effects of the utility model are the grout sleeve of polygon prism structure half of the present utility model, sleeve can be made to be in the milk
Linkage section is tightened with convenient use common wrench during bar connecting, improves operating efficiency, ensures threaded connection quality.The technical side
Case is especially suitable for half grout sleeve using casting technique manufacture.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the grout sleeve of the utility model polygon prism structure half.
Fig. 2 is the side view of the grout sleeve of the utility model polygon prism structure half.
Fig. 3 is the dimensional structure diagram of the grout sleeve of the utility model polygon prism structure half.
In figure：1st, sleeve body, 11, grouting mouth, 12, thick liquid discharge mouth, 13, threaded connection section, 14, grouting linkage section.
Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.
As Figure 1-3, it is the utility model optimum embodiment, a kind of grout sleeve of polygon prism structure half, including sleeve
Body 1, the one end of sleeve body 1 are threaded connection section 13, and the other end is grouting linkage section 14, and grouting is provided with sleeve body 1
Mouthfuls 11 and thick liquid discharge mouth 12, respectively close to the both ends of grouting linkage section 14, threaded connection section 13 has mouth 11 and the thick liquid discharge mouth 12 of being in the milk
Internal thread, at least there are two planes on the outer wall of threaded connection section 13.
The outer wall of the grouting linkage section 13 is shaped as equilateral polygon prism structure.The side number of the polygonal prism is six
Side.
The grout sleeve of polygon prism structure half, sleeve grouting linkage section can be made to be twisted with convenient use common wrench during bar connecting
Tightly, operating efficiency is improved, ensures threaded connection quality.The technical scheme is especially suitable for half grouting using casting technique manufacture
Sleeve.
Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, pass through above-mentioned description, related work people
Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real
The content being not limited to new technical scope on specification, it is necessary to which its technology is determined according to right
Property scope.
