Embodiment
Concrete precast pile, there are to save timber and steel, durable in use, cheap, be widely used in
Waterwork, industrial building, the foundation engineering of civil buildings and bridge, be also commonly used for side slope and pattern foundation pit supporting structure antiskid or every
Water.For the ease of stake is longitudinally connected with stake, in the both ends difference mounting receptacle 1 and plug of the pile body of concrete precast pile
2, the center line of jack sleeve 11 is consistent with the centerline direction of corresponding plug 2, and or phase parallel with the center line of pile body
Overlap.Plug 2 is protruding from the end face of pile body, and root and the pile body of plug 2 are fixed, and the top of socket 1 is not stretched out
The other end of pile body, so as to when the plug of two stakes is connected with socket, plug is just inserted in socket, two stakes
End face and end face offset cooperation.Cooperation is close, resistance to plucking is counter-bending, intensity is high.
As shown in the drawings, forbid what is outwards extracted after a kind of resistance to plucking bending resistance quick union, including socket 1, insertion socket 1
Plug 2, plug 2 be cross section from the tapered rod-like element of the head of plug 2 to root gradual change, socket 1 includes having host cavity 12
Jack sleeve 11, can be slideably positioned in along the centerline direction of jack sleeve 11 in host cavity 12 spool mechanism 13, set
Cause spool mechanism 13 that there is the elasticity towards the top mobile trend of jack sleeve 11 between jack sleeve 11 and spool mechanism 13
Part 14, the cross section of host cavity 12 is gradually small from bottom of chamber to opening gradual change, and spool mechanism 13 is arranged at jack sleeve 11 including multiple
Host cavity side wall chipware 131.As shown in Figure 2-4, the bottom of jack sleeve 11, which has, is used to connect reinforcing bar end inside pile body
The limit chamber of head.The root of plug can be connected with reinforcing bar inside pile body.
Resistance to plucking bending resistance quick union has not-connected status and connection status：
When resistance to plucking bending resistance quick union is under not-connected status, spool mechanism 13 is upspring by elastic component 14, and spool mechanism 13 leans on
It is bordering on the top of jack sleeve 11, it is mutually close between two neighboring chipware 131, surround what is inserted for plug 2 between multiple chipwares 131
Insert chamber 132.
When resistance to plucking bending resistance quick union is under connection status, spool mechanism 13 is close to the top of jack sleeve 11, plug 2
It is inserted in insertion chamber 132, chipware 131 is filled between the lateral wall of plug 2 and host cavity side wall.
Insert the cross section of chamber 132 and the shape of cross section of plug 2 is all consistent, also, the upper surface of chipware 131 is towards insertion
The slope 1311 that chamber 132 tilts down.It is all rounded in the present embodiment, when plug 2 inserts against spool mechanism 13, very
Easily plug 2 is imported in insertion chamber 132.The madial wall of chipware 131 is arcwall face, the circular in cross-section of plug 2, when resistance to plucking resists
Curved quick union is under connection status, and madial wall and the lateral wall of plug 2 of chipware 131 fit, and chipware 131 is real with plug 2
Existing face contact.
Loop-shaped outside cross section at the chipware 131 of spool mechanism 13, it is consistent with the shape of cross section of host cavity 12.As received
The cross section of cavity volume 12 is square, and the cross section of spool mechanism 13 is also in conformality, and spool mechanism 13 can be prevented in host cavity
Horizontal looseness in 12.In this implementation, the cross section of host cavity 12 and the cross section of spool mechanism 13 are all rounded.
Spool mechanism 13 has various embodiments：
Embodiment one：As shown in accompanying drawing 2,3, the chipware 131 of spool mechanism 13 has four, and spool mechanism 13 also includes being located at four
The combination bottom plate 133 of the individual lower section of chipware 131, combines the bottom plate back-up ring 1331, Mei Gexin for having a circle protruding upward on bottom plate 133
The bottom of part 131 is inserted in the stopper slot that host cavity side wall is formed with bottom plate back-up ring 1331, and elastic component 14 is arranged at combination bottom plate
Between 133 lower surface and the host cavity bottom 15 of jack sleeve 11.
Embodiment two：Not shown, chipware 131 is slideably positioned in host cavity side wall by sliding the track of extension up and down.
Elastic component can be set between single chipware 131 and jack sleeve 11, can also be participated in implementing one, in multiple chipwares 131
Lower section sets a combination bottom plate, and elastic component is arranged between the lower surface of combination bottom plate and the host cavity bottom of jack sleeve.Chipware
131 runnings are relatively stable.
Embodiment three：As shown in Figure 4, spool mechanism 13 also includes the chipware chassis positioned at multiple lower sections of chipware 131
133 ', mutually it is fixedly connected between chipware chassis 133 ' and multiple chipwares 131.Elastic component 14 is arranged at the following table of chipware chassis 133 '
Between face and the host cavity bottom 15 of jack sleeve 11.Chipware chassis 133 ' includes the base portion 1331 ' positioned at middle part, by base portion 1331 '
The multi-disc slender type shell fragment bar 1332 ' that outwards stretches out upwards of edge, shell fragment bar 1332 ' is slender type, and elasticity is larger, does not influence
Displacement or elastic deformation caused by chipware 131 during the insertion insertion chamber 132 of plug 2.The top of shell fragment bar 1332 ' and the bottom of chipware 131
Correspond and mutually one entirety of fixed composition, fixed form such as screw are fixed, weld, be integrally formed.Opened on base portion 1331 '
Provided with through upper and lower guide through hole, host cavity bottom 15 has the guide rod 151 stretched out upwards, and it is logical that guide rod 151 is inserted in guiding
In hole, so that spool mechanism 13 is relatively stable when moving up and down.Elastic component 14 is sheathed on guide rod 151.
Example IV：As shown in Figure 5, the difference of example IV and embodiment three is, is not oriented on base portion 1331 '
Through hole, there is no guide rod 151 on host cavity bottom 15, elastic component is directly contacted between host cavity bottom 15 and base portion 1331 ' yet.
Operation principle：The host cavity oral area of jack sleeve is small and gradually big to the gradual change of intracavitary bottom, pin head it is big and to root
Gradual change is tapered, and when plug 2 inserts, the head of plug 2 contradicts the top of spool mechanism 13, overcomes the elastic force of elastic component 14,
Spool mechanism 13 is promoted to be moved to bottom, as host cavity lower space becomes big, the top of the insertion chamber 132 of spool mechanism 13 is opened
Expanding at mouthful, it is allowed to plug 2 enters insertion chamber 132, and spool mechanism 13 just moves in the presence of elastic component 14 to top to be resetted,
When plug is with socket connection status, chipware is just located between plug and jack sleeve, because the host cavity top of jack sleeve is small,
Plug is just restricted in host cavity, and the lateral wall of plug and the madial wall of chipware are inconsistent, the lateral wall and jack sleeve of chipware
Madial wall it is inconsistent, contact of the face with face make it that twisting can not be bent between plug and socket, and plug head it is thick and
It is minimum at host cavity oral area at the top of socket so that the more to pull out the more tight between plug and socket.
As above, we are illustrated fully according to spirit of the invention, but the present invention is not limited to above-described embodiment
And implementation.The practitioner of correlative technology field can carry out different changes in the range of the technological thought license of the present invention
And implement.
