Description
Technical field
The present invention relates to a kind of method and device applied to bar connecting in building structure, the present apparatus is suitable for cast-in-place apply
The connection of the steel bar vertical of work and assembled architecture, horizontal connection and oblique connection.
Background technology
Steel concrete supporting form includes mainly in existing building structure：Cold extrusion is connected and is threadedly coupled.
Cold extrusion connection is, by squeezing steel sleeve outer circle, to make steel bushing using the steel sleeve with high ductility moderate strength
Pipe generates plastic deformation, and steel bushing pipe orifice tightly bonds Ribbed Bar, to realize the connection of two Ribbed Bars.
Threaded connection includes taper thread connection, upsetting straight connects and thread rolling bar joints, by special equipment plus
Connected two reinforcing bars of work, by two it is end reinforced produce the steel bar head with respective threaded, then with in corresponding
Two bar connectings are realized bar connecting by the branch sleeve of screw thread.It needs first to screw in branch sleeve into a reinforcing bar when connection
On silk head, then another reinforcing bar is screwed in sleeve and tightened again, makes two bar connecting power transmissions.In its connection procedure
At least a reinforcing bar should be rotated and is also axially moveable.Therefore existing bar connecting mode is only applicable to single steel bar company
It connects.
With the development of construction industry, the continuous improvement of building construction technology gradually uses reinforcing bar component in construction
Construction by the integral reinforced mesh of more reinforcement fabrications, steel reinforcement cage, then carries out reinforcing bar component that is, before bar connecting construction
Integrated connection.In this reinforcing bar component connection construction, reinforcing bar can only be axially moveable, and cannot be rotated.Therefore, using existing steel
Muscle connection type cannot achieve the integrated connection of reinforcing bar component.As widelyd popularize assembled architecture technology now, due to structure
Part exposed steel bar cannot rotate, therefore existing mechanical connection technique of reinforcement can not achieve bar connecting, structure in assembled architecture
Bar connecting between part can only carry out bar connecting with grout sleeve, and grout sleeve cost is high, working procedure very complicated,
The quality of grouting construction directly affects construction quality, and bar connecting quality is relatively difficult to guarantee.
Invention content
A kind of bar connecting dress is provided the technical problem to be solved by the present invention is to overcome the above-mentioned insufficient of the prior art
It sets, can adapt to use under the not revolvable architectural environment of reinforcing bar.
Technical solution is used by the present invention solves the above problems：
Reinforcing steel bar connecting device, it is characterised in that：Including being connected reinforcing bar, by from lock tube, positioning from lock tube and casing；
The connected reinforcing bar is the threaded reinforcing bar in end；
The internal thread by penetrating through and being arranged from lock tube endoporus and connected screw thread steel coordinates, by from outside lock tube one end
Surface is with one section by from lock tube external screw thread；
It is described to position the internal thread for penetrating through and being arranged from lock tube endoporus with screw thread steel cooperation, it positions from lock tube one end outer surface band
There is one section of positioning from lock tube external screw thread；
Described sleeve pipe is both ends open, be respectively set in the endoporus of both ends open with by from lock tube external screw thread and positioning from lock tube
The mating internal thread of external screw thread.
Preferably, it is described by from lock tube internal thread and pass through from lock tube external screw thread be different screw pitch screw thread.
Preferably, the positioning from lock tube internal thread and is positioned from the screw thread that lock tube external screw thread is different screw pitch.
Preferably, described by the way that the shape adaptable with the tool of rotation is arranged without thread segment from lock tube outer surface, in this way
It can preferably be rotated by from lock tube by tool.
Preferably, the shape adaptable with the tool of rotation is arranged without thread segment from lock tube outer surface for the positioning, in this way
By tool can preferably rotational positioning from lock tube.
Preferably, described sleeve pipe outer surface is set as the shape being adapted with rotation tool, in this way can be more by tool
Revoling tube well.
Preferably, described non-threaded outer surface full-size is put on by self-locking to be less than by from lock tube external screw thread path ruler
Very little, such casing can pass through by from lock tube, facilitating installation casing.
Preferably, the positioning self-locking puts on non-threaded outer surface minimum dimension and is more than positioning from lock tube external screw thread major diameter ruler
It is very little, be positioned such that from lock tube can limit casing, screw connected reinforcing bar.
The connected steel bar end screw thread can be rolling straight thread or be upsetting straight, and screw thread can be straight spiral shell
Line or taper thread.
The advantage of the invention is that：1, setting covers the pitch difference of upper external screw thread and internal thread by self-locking, realizes reinforcing bar
Self-locking connection in the case where being unable to rotation situation, no matter be connected two reinforcing bars can among casing to top, by from lock tube,
Externally threaded pitch difference realizes that self-locking is fastenedly connected.2, reinforcing bar by screw thread when pulling force or pressure by all can realizing power transmission.3, exist
While ensuring reinforcing bar ultimate bearing capacity, also improve reinforcing bar and make deformation performance in working load, substantially improve reinforcing bar by
Force environment improves the degree of safety and quality of building structure.4, this method and device are used in assembled architecture, are ensureing to build
While building structure quality, it is also greatly reduced cost, simplifies construction technology, speed of application is fast, not will produce current use
The decline for the bar connecting quality that component disturbance generates when grout sleeve, can accomplish real dry construction.
