Description
Technical field
The invention belongs to mechanical connection technique of reinforcement field, more particularly to a kind of steel concrete supporting structure and installation side
Method.
Background technology
Steel concrete supporting is a new reinforcing steel bar Joining Technology, " the third generation reinforcing bar being referred to as after colligation, electric welding
Joint ", has the advantages that strength of joint higher than parent material of reinforcement rebar, speed than being welded fast, pollution-free, saving steel.It is common at present
Steel concrete supporting method has three kinds：(1) extrusion socket joint joint, makes connection reinforcing bar that plasticity occur with sleeve by extruding force
Deform and be closely engaged, but hydraulic test is heavier, site operation inconvenience；(2) taper thread jointing, by steel bar end
It is engaged with the tapered thread of connector termination and forms jointing, taper thread silk head prefabrication, site operation only needs moment of torsion
Spanner, it is easy to operate, but taper thread jointing quality is not sufficiently stable, and is generally used for joint quality class requirement not high
Situation；(3) straight thread joint, is the international newest trend of the strong ties such as reinforcing bar, and joint quality is reliable and stable, bonding strength
Height, convenient and quick construction, the advantage of its existing taper thread joint easy construction overcomes the unstable shortcoming of quality of connection again,
Therefore the appearance of straight thread joint technique brings qualitative leap to rebar connecting technology.
Common single sleeve straight screw connection or taper thread connection needs docking reinforcing bar freely to rotate, by reversing steel
Muscle ensures mutually to be held out against in sleeve middle position, and can improve quality of connection can reduce the residual deformation of joint again.But for pre-
Concrete component processed and reinforcing bar tied framework, fix because of reinforcement location with precast concrete or reinforcing bar tied framework position, single
Root reinforcing bar cannot accomplish free rotation.Generally connect on reinforcing bar plus long filament head at one section during practice of construction, in advance branch sleeve
Screw in plus long filament head, after reinforcing bar contraposition, branch sleeve by adding long filament head to screw in another reinforcing bar, the drawbacks of this kind of method
It is, branch sleeve Smooth Rotation between connection reinforcing bar, it is impossible to which applying moment of torsion holds out against reinforcing bar, and the residual deformation of this connection is very
Greatly, joint quality it is difficult to ensure that, and need reinforcing bar accurate positioning, construction precision to have high demands.
Building industrialization is the development trend of current Building Trade in China, be realize the environmental protection of four section one green building it is important
Step.The key character of building industrialization is exactly that most of component is prefabricated in the factory, and simple connecting structure is only done just in scene
Structure stress requirement can be met, the bar connecting of prefabricated components must be completed at the scene.The joint connection in site of prefabricated components reinforcing bar is normal
The method seen has：Reinforced bar sleeve grouting connection and reinforcing bar slurry anchor overlap joint connection.The working mechanism of reinforced bar sleeve grouting jointing
It is to give grouting material in grout sleeve to have higher compression strength, while grouting material has micro-expansibility, when slurry runs into sleeve
Constraint when, produce larger pressure in slurry and sleeve lining, and thus pressure produces frictional force to transmit axial stress, covers
Position accuracy requirement of the pipe grouting connection to branch sleeve and reinforcing bar is very high, and requires that grouting material has mobility and microdilatancy
Property, difficulty of construction is very big, is the fast-developing bottleneck of building industrialization.Reinforcing bar slurry anchor overlap joint connection also has that difficulty of construction is big, fills
The features such as stock quality hardly possible control, and its quality of connection reliability is not high.
The content of the invention

Cap is connect using outer-hexagonal head structure, there is external screw thread on the stud, the mechanical connection sleeve is screwed on the stud.
Further, there is internal thread, the internal thread and external screw thread are oppositely oriented in the attachment cap.
Further, the internal thread and external screw thread are straight thread or taper thread.
Further, the mechanical connection sleeve is constructed using outer-hexagonal head structure or round end.
The present invention also provides a kind of installation method of above-mentioned steel concrete supporting structure, specifically includes following steps：
(1) mechanical connection sleeve is screwed in the shaft with attachment cap stud；
(2) to needing the first connection reinforcing bar of connection and the end machining of the second connection reinforcing bar to make screw thread silk head；
(3) band attachment cap stud and mechanical connection sleeve are revolved the attachment cap with attachment cap stud as an entirety
Enter the first connection reinforcing bar；
(4) fixing band attachment cap stud, screws in second and connects reinforcing bar mechanical connection sleeve；
(5) solid mechanical branch sleeve and the second connection reinforcing bar, using torque wrench to the attachment cap with attachment cap stud
Apply moment of torsion, fasten steel bar connecting structure.
Beneficial effects of the present invention are as follows：A kind of steel concrete supporting structure that the present invention is provided is connected reinforcing bar with two ends
Complete contraposition to screw in after connection, moment of torsion is applied to band attachment cap stud, it is possible to reduce the residual deformation of bar connecting, it is ensured that connection
Quality.The present invention can be used for two ends connection reinforcing bar situation about cannot rotate, be mainly used in precast reinforced concrete structure and
Bar connecting between overall reinforcing bar tied framework, it can also be used to the connection of regular reinforcement.
