Ask very high, member processing process is complicated, and a kind of reinforced bar sleeve of internal diameter generally can be only applied to a kind of reinforcing bar of diameter, and cover
Cylinder is general all long, and sleeve requires special prefabricated, greatly increases project cost；Jointing is wanted in tradition machinery connection
It asks higher, needs to meet bonding strength requirement according to a variety of grades of connector ductility point to adapt to a variety of reinforced steel bar strengths, need to throw
Enter excessive cost.Therefore for connection type described above under the premise of guaranteeing that connection is reliable, most cost is excessively high, application range
Narrow, difficulty of construction is larger.
Utility model content
The utility model aims to solve the problem that the problem of reinforcing bar connects in the structures such as existing assembling frame, shear wall,
And a kind of easy construction, the bonding strength that propose are high and in the case where guaranteeing structure connection secured premise, can shorten steel reinforcement abutting joints
Joint dimension substantially reduces difficulty of construction and is docked and connect with straight screw sleeve connection with a kind of fabricated construction for reducing project cost
Head.
In order to solve the above-mentioned technical problem, the utility model adopts the technical scheme that
A kind of fabricated construction straight screw sleeve connection banjo fixing butt jointing, including steel bushing, connection reinforcing bar and grouting material, it is special
Sign is: the connection reinforcing bar is that processing is passed through with fluted and raised reinforcing bar in top；The top of two connection reinforcing bars is opposite
Setting, groove and protrusion are completely engaged so as to which two connection reinforcing bars link together, and form joggle and lock form；Two
Its periphery of part of connection reinforcing bar connection is arranged with the steel bushing, is perfused between the steel bushing and two connection reinforcing bars
State grouting material.
Further, the steel bushing is common seamless steel pipe or straight seam welded pipe.
Further, the connection reinforcing bar is the Ribbed Bar that top reserves fixed dimension groove and protrusion by processing.
Further, the Ribbed Bar that the connection reinforcing bar is diameter 6mm or more.
Preferably, the connection bar diameter is 16mm.
Further, the connection bar diameter that the length of the steel bushing is 3 times -6 times.
Preferably, the length of the steel bushing is 80mm, wall thickness 4-8mm.
Further, the groove and the continuous setting of protrusion.
Further, the groove and protrusion are the multiple groups being continuously arranged.
Further, two connection reinforcing bars after connection, axis are overlapped；The inner wall of the steel bushing with connect outside reinforcing bar
The connection bar diameter that the distance between wall is 0.2-0.8 times.
Compared with the existing technology, the utility model has the following technical effect that
It according to above-mentioned technical proposal, connects reinforcing bar and is connected by reinforcing bar top groove and protrusion, realize connection reinforcing bar
Dock self-locking, this method is simple to manufacture, and can greatly shorten steel bushing length.Reinforcing bar is connected by groove and protrusion connection, and
It combines together with the grouting material in injection steel bushing, when improving the globality of connecting elements, and saving in the construction process
Between, keep higher precision.The connection reinforcing bar of the utility model improves docking steel by reserved groove and the complete docking of protrusion
The overall structure performance of muscle, and then steel bushing length can be greatly reduced, and connect that safe and reliable, easy to operate, material saving is low
It is carbon, energy conservation and environmental protection, practical, have a wide range of applications space.From the current study, the connection of precast concrete reinforcing bar
Node is generally longer, and previous grout sleeve connection is generally used for the prefabricated components reinforcing bar company of bar diameter relatively thick (>=16mm)
It connects, has the shortcomings that construction complexity, high cost.This kind it is easy for construction, cheap, connection is reliable, reasonable stress and it is effective
New reinforcing steel bar is connected mode, for improving construction quality in fabricated construction engineering at this stage, accelerating speed of application, raising
Labor productivity reduces cost, has a very important significance.
