Description
Technical field
The utility model belongs to mechanical connection technique of reinforcement field, more particularly to a kind of steel concrete supporting structure.
Background technology
Steel concrete supporting is a new reinforcing steel bar Joining Technology, is referred to as " the third generation reinforcing bar 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 need the docking reinforcing bar can 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 connected at one section during practice of construction and silk head is lengthened on reinforcing bar, in advance branch sleeve
Screw in and lengthen silk head, after after reinforcing bar contraposition, during branch sleeve is screwed in another reinforcing bar by lengthening silk head, the drawbacks of this kind of method
It is, branch sleeve Smooth Rotation between reinforcing bar is connected, it is impossible to which applying moment of torsion holds out against reinforcing bar, 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 requirement is high.
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 compression strength higher, 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.
Utility model content
For above-mentioned deficiency, the utility model provides a kind of steel concrete supporting structure, solves prefabricated components scene steel
The problem that muscle connection construction difficulty is big, quality of connection reliability is not high.
In order to achieve the above object, the technical scheme that the utility model is used is as follows：A kind of steel concrete supporting structure,
Including band attachment cap stud and mechanical connection sleeve, the band attachment cap stud is made of one piece by stud and attachment cap, its
In, attachment cap uses outer-hexagonal head structure, has external screw thread on the stud, and the mechanical connection sleeve is screwed in the stud
On.
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 beneficial effects of the utility model are as follows：A kind of steel concrete supporting structure that the utility model is provided and two ends quilt
After connection reinforcing bar completes contraposition screw-in connection, moment of torsion is applied to band attachment cap stud, it is possible to reduce the residual deformation of bar connecting,
Ensure quality of connection.The utility model can be used for the situation that two ends connection reinforcing bar cannot be rotated, and be mainly used in precast reinforced
Bar connecting between concrete component and overall reinforcing bar tied framework, it can also be used to the connection of regular reinforcement.
