Description
Technical field
The utility model is related to a kind of reinforcing steel bar connecting sleeve tube, especially a kind of screw-threaded coupling Split type steel bar branch sleeve.
Background technology
In cast-in-situ steel reinforced concrete engineering construction, larger-diameter bar connecting continues to use always traditional strapping for many years
Construction does not need knack worker although its easy construction, and weatherproof wastes steel, the eccentric connection of reinforcing bar
Additional shear stress is will produce, it is bad that connector transmits power effect；Cloth muscle density conference, which gives to pour to vibrate, brings difficulty, and influence is vibrated close
Reality.And being welded to connect is influenced such as arc welding, flash welding and electroslag pressure welding by many factors, there are some it is unstable because
Element, such as building site capacitance are insufficient, and spread of voltage can influence welding quality, and certain areas climate is moist, temperature is too low, steel
The factors such as chemical composition is unstable also influence joint quality.The docking of steel reinforcement cage is also always puzzlement unit in charge of construction in construction
One problem, steel reinforcement cage docking time typically constitute from 70~80% or so of cage time under entire steel reinforcement cage, therefore the docking of steel reinforcement cage
Speed directly influences the time of lower cage, and area especially bad in some geological conditions threatens the quality of pile.
Inventor has developed a kind of cone locking Split type steel bar branch sleeve before, will applying man-hour requirement forcing press
It will be outside the both ends of the Split type steel bar connecting cylinder of the cone angle of two inner cone lock sleeves and both ends with male cone (strobilus masculinus) by forcing press
The cone angle of the conical surface completely attaches to, and will be engaged in the steel bar head in the cylinder of Split type steel bar connecting cylinder of the both ends with male cone (strobilus masculinus) and locks
Tightly, it is allowed to be connected and realize the purpose of connection.This connection type can improve construction quality, shorten construction period, reduce
Construction cost, but this form of construction work is completed by means of forcing press, increases working procedure, consumes the muscle power of construction personnel.
Invention content
The problem of the purpose of this utility model is regarding to the issue above provides a kind of reinforcing steel bar connecting sleeve tube, is used for
The eccentric connection for solving reinforcing bar will produce additional shear stress, connector transmits that power effect is bad, the construction time is long, reduces working procedure
The problem occurred Deng current construction.
The purpose of this utility model is achieved in that including Split type steel bar connecting cylinder, two lock sleeves, feature
It is：The both ends of the internal diameter of Split type steel bar connecting cylinder and the outer diameter of Split type steel bar connecting cylinder are screw thread respectively, and wire cutting is used in combination
Into two by the cutting of Split type steel bar connecting cylinder integrated symmetric, the internal diameter of two lock sleeves is screw thread, and two lock sleeves pass through interior
The screw thread of diameter is separately mounted to the outer diameter both ends of Split type steel bar connecting cylinder.
The Split type steel bar connecting cylinder entire length is：20-150mm, the internal diameter of the Split type steel bar connecting cylinder
The thread form angle of screw thread be：55 ° -80 °, the screw pitch of the screw thread of the internal diameter of the Split type steel bar connecting cylinder is：1-5mm, institute
The screw thread effective length of the internal diameter for the Split type steel bar connecting cylinder stated is 20-150mm, the Split type steel bar connecting cylinder it is outer
The thread form angle of the screw thread at the both ends of diameter is：55 ° -80 °, the screw thread at the both ends of the outer diameter of the Split type steel bar connecting cylinder
Screw pitch is：The screw thread effective length of 1-5mm, the both ends of the outer diameter of the Split type steel bar connecting cylinder are 4-75mm.
The Split type steel bar connecting cylinder is fabricated by two kinds of ferrous materials.
The length of two lock sleeves is：4-75mm, the form of thread angle of the internal diameter of described two lock sleeves
For：55 ° -80 °, screw pitch is：The screw thread effective length of 1-5mm, the internal diameter of described two lock sleeves are 4-75mm.
Two lock sleeves are fabricated by two kinds of ferrous materials.
Two kinds of ferrous materials, the first ferrous material are No. 45 steel, second of black gold
Category material is 40Cr.
The utility model has the beneficial effects that：It reduces by one of working procedure, improves construction quality, shortens construction period, drop
Low construction cost, the physical demands for mitigating construction personnel.
Description of the drawings：
Attached drawing 1 is the external structure schematic diagram of the utility model
Attached drawing 2 is the internal structure schematic diagram of Fig. 1
Specific implementation mode：
By Fig. 1-2 it is found that 1, two lock sleeve 2a2b of Split type steel bar connecting cylinder, the internal diameter of Split type steel bar connecting cylinder 1
Both ends with the outer diameter of Split type steel bar connecting cylinder 1 are screw thread respectively, are used in combination wire cutting that Split type steel bar connecting cylinder 1 is whole right
Claim cutting into two.When construction, the screw thread silk head of two reinforcing bars to be connected is put into Split type steel bar connecting cylinder 1, is not needed
The rotation of reinforcing bar can be achieved with the threaded engagement in the screw thread silk head of reinforcing bar and the cylinder of Split type steel bar connecting cylinder 1, will divide later
Body formula bar connecting cylinder 1 is fastened, and is connect the internal diameter whorl of two individual lock sleeve 2a2b with Split type steel bar by spanner
