Detailed description of the invention
Fig. 1 is the sectional view of the utility model；
Fig. 2 is the first sleeve feature profile figure of the utility model；
Fig. 3 is the second collar tube sub-assembly sectional view of the utility model.
Specific embodiment
Make furtherly below with reference to technical effect of the attached drawing to the design of the utility model, specific structure and generation
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
If Fig. 1 is simultaneously combined shown in Fig. 2 and Fig. 3, a kind of self-locking mechanical connection sleeve, including first sleeve component and second
Collar tube sub-assembly, second collar tube sub-assembly include the second reinforcing bar connector 8, thimble 7, first sleeve 5, the second casing 6, first folder
Piece 3 and second intermediate plate 4, the thimble 7 are connected to one end of the second reinforcing bar connector 8, and the first sleeve 5 is sleeved on the second steel
The one end of muscle connector 8, second casing 6 are sleeved on the one end of first sleeve 5, and the setting of first clamping piece 3 is the
On the inner peripheral wall of two casings 6, the second intermediate plate 4 is arranged on the inner peripheral wall of first sleeve 5.
Wherein, the first sleeve component includes plug 1 and the first reinforcing bar connector 2, the first reinforcing bar connector 2
One end is connected to one end of plug, connect in the other end insertion first clamping piece 3 of the first reinforcing bar connector 2 with thimble 7.
In addition, the first reinforcing bar connector 2 is provided with inverted draw cut 13 with 7 junction of thimble, the inverted draw cut 13 is provided with
Cross-notching 10 is further sleeved with compressed spring 9 and washer 14 in the first sleeve 5.
Wherein, the other end of the first reinforcing bar connector 2 connects reserved steel bar 11, and the second reinforcing bar connector 8 connects
Connect reinforcing bar 12, the shape of the first clamping piece 3 and second intermediate plate 4 is wedge shape.
The utility model is by self-locking mode, under pressure, realizes the connection of reinforcing bar, which can be pre-
Component processed from gravity, or precompression, use is more convenient, and compared with grout sleeve, switching performance is no longer decided by fill
The quality and compactness of slurry, while complicated grouting construction process is also eliminated, only realized by simple construction technology
The performance requirement of I grades of connectors of reinforcing bar.
Implementation steps：Before use, the first reinforcing bar connector of first sleeve component with it is pre- in prefabricated components to be installed
Reinforcing bar is stayed to be connected, connection type can be using the modes such as straight screw connection, the second reinforcing bar connector of the second collar tube sub-assembly and pre-
Embedded bar in component processed is connected, and is embedded in component in advance；Also interchangeable uses, i.e., is embedded in first sleeve component in advance prefabricated
In component, the second collar tube sub-assembly is connected with the reserved steel bar of prefabricated components to be installed.
In use, being pressed into it in second collar tube sub-assembly, (F power is oneself of component by first sleeve component applied force F
Gravity, or the precompression that outside provides).In process of press in, the plug of first sleeve component and first clamping piece and the
The surfaces of two intermediate plates contacts, but due to intermediate plate A, B be not affected by it is smaller perpendicular to the pressure of plug or suffered pressure, still
Fail to provide enough frictional force.Washer and compressed spring play a part of to support first clamping piece and second intermediate plate, keep intermediate plate
Between plug and the gap of casing, so that its subsequent can provide frictional force.Notch to first sleeve component is contacted to thimble
When, due to the effect of thimble, notch is strutted, is transported to provide first clamping piece and second intermediate plate to first sleeve component direction
Dynamic power.
Since first clamping piece and second intermediate plate are wedge shape, the power along first sleeve component direction acted on intermediate plate, meeting
The pressure perpendicular to plug is generated, to generate frictional force in the contact surface of first clamping piece and second intermediate plate and plug.With
Sleeve component enters the increase of the second collar tube sub-assembly length, which is also gradually increased.Finally when first sleeve component
After plug fully enters the second collar tube sub-assembly, the frictional force between intermediate plate and plug reaches maximum, at this time first sleeve component
It is locked with the second collar tube sub-assembly, completes the connection of reinforcing bar.After the completion of connection, the attachment device under a stretching force, plug and folder
Frictional force is generated between piece A, B, has resisted the effect of pulling force, connector tensile strength is able to achieve and is equal to the practical drawing for being connected reinforcing bar
Disconnected intensity is not less than 1.10 times of Steel Bar Tensile Strength standard values, that is, has reached the requirement of technical regulation.
The preferred embodiments of the present invention have been described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality according to the design of the utility model on the basis of existing technology in domain
Available technical solution is tested, it all should be within the scope of protection determined by the claims.
