Description
Technical field
The invention belongs to technical field of buildings, is related to a kind of unitary nut for connector.
Background technology
The applicant pushes up pile extension and prefabricated component [Authorization Notice No. in the patent applied before under spiral shell:
CN100348803C] in, by drawing nut, top pull nut and pile pile longitudinal reinforcement to form positioned at rising for pile pile both ends, wherein, drawing of rising
Nut and top pull nut are internal thread structure, and for the internal thread to hale screw thread, cap bottom center is provided with reinforced hole, the week of reinforced hole
Side is reinforcing bar end upset chuck, and the both ends upsetting of pile pile longitudinal reinforcement is connected in chuck into heading.The pile for prestressed pipe pile extension by
Rise and draw nut, top pull nut, combination sleeve, intermediate sleeve and connecting rod to form, wherein, rising, to draw nut and top pull nut be internal thread
Structure, for the internal thread to hale screw thread, cap bottom center is provided with reinforced hole, and the periphery of reinforced hole is reinforcing bar end upset chuck, pile pile
The both ends upsetting of longitudinal reinforcement is connected in chuck into heading；Connecting rod one end is dentalation, and the other end is external thread structure；Two
Piece or multi-disc combination sleeve be located in top pull nut, it is described combination sleeve on the inside of be in dentalation and with the dentation knot in connecting rod
Structure matches；Intermediate sleeve is external thread structure, is screwed in top pull nut and positioned at two panels or multi-disc combination sleeve top；Docking
When, connecting rod one end draws the screw thread of nut to be screwed on rising, and the other end combines sleeve with the two panels in top pull nut or multi-disc and formed
Clamping.
Docking calculation between the prestressing force prefabricated component, the end for two prefabricated components to be docked are respectively equipped with several
Rise and draw nut and be located at several corresponding top pull nuts, two panels or multi-disc combination sleeve in top pull nut, it is middle
Cover and be screwed in top pull nut and in two panels or multi-disc combination sleeve, connecting rod one end is screwed on the drawing nut that rises, the other end
Sleeve is combined with the two panels in top pull nut or multi-disc and forms clamping.
Above-mentioned top pull nut and the secure fit that is spirally connected of intermediate sleeve are used for positioning sleeve, when connecting rod is inserted into intermediate sleeve
In or after the completion of grafting shearing force can be produced to intermediate sleeve, intermediate sleeve is damaged, therefore the structure of top pull nut still has
Perfect space.
The content of the invention
A kind of regarding the issue above, the present invention provides integral type spiral shell for connector that structural strength is high
It is female.
To reach above-mentioned purpose, present invention employs following technical proposal：A kind of unitary nut for connector, bag
Include nut body, one end inside the nut body is has a female connecting cavity, the other end inside nut body
With the chuck that the direction of axis line to nut body is prominent, among the chuck there is the grafting that connection-peg can be allowed to be inserted into lead to
Road, grafting passage connection connecting cavity.
In the above-mentioned unitary nut for connector, it is in round platform that the chuck has close to one end of connecting cavity
The Access Division of taper, the grafting passage is in the small round tapered of big lower mouth suitable for reading.
Also having one in the above-mentioned unitary nut for connector, between the Access Division and connecting cavity is in
The stage portion of circular ring shape.
In the above-mentioned unitary nut for connector, the nut body has in more close to one end of chuck
The location division of side column shape.
In the above-mentioned unitary nut for connector, the location division is cubic cylindricality or hexagonal prism shape.
Compared with prior art, the advantage of the invention is that：Nut body is an integral structure with chuck, can be realized
The function of clamping, and structural strength can be improved；The chuck other end is hatch frame, can be used to connect miscellaneous part.
Brief description of the drawings
Fig. 1 is structure diagram provided by the invention；
Fig. 2 is the application principle figure of the present invention.
In figure：Nut body 10, connecting cavity 11, chuck 12, grafting passage 13, Access Division 14, stage portion 15, location division
16th, snap ring 20, connection-peg 21, packing ring 22, spring 23, connection bolt 24.
Embodiment
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.
As depicted in figs. 1 and 2, it is shown, a kind of unitary nut for connector, including nut body 10, it is described
One end inside nut body 10 is to have female connecting cavity 11, and the other end inside nut body 10 has to nut sheet
The chuck 12 that the direction of axis line of body 10 protrudes, the shape of chuck 12 and the outer surface of snap ring 20 match, the chuck 12
Centre has the grafting passage 13 that connection-peg 21 can be allowed to be inserted into, the grafting passage 13 connection connecting cavity 11.
Chuck 12 has the Access Division 14 in round tapered close to one end of connecting cavity 11, and the grafting passage 13 is presented
The small round tapered of the big lower mouth of mouth, positioning function can be formed to connection-peg 21.Also have one between Access Division 14 and connecting cavity 11
A stage portion 15 in circular ring shape.
Nut body 10 has the location division 16 in Polygonal column shape close to one end of chuck 12, with spanner or other instruments
Location division can be fixed, so that rotating nut body 10.Preferably, location division 16 is cubic cylindricality or hexagonal prism shape.
The present invention operation principle be：As shown in Fig. 2, being put into snap ring 20 in connecting cavity 11, snap ring 20 is pasted with Access Division 14
Close, and be sequentially placed into packing ring 22 and spring 23, connection bolt 24 and spring 23 after 11 threaded of connecting cavity hold out against packing ring 22 and
Snap ring 20, packing ring 22 are positioned with stage portion 15, and connection-peg 21 is inserted into from grafting passage 13 and blocks snap ring 20 so that grafting
First 21 connect and fix with nut body 10.
Since the chuck 12 of nut body 10 is integrally fixed on nut body, integral structure is in substance form,
Shearing force will not be formed during grafting or after the completion of grafting, thus structural strength is higher.
Specific embodiment described herein is only to spirit explanation for example of the invention.Technology belonging to the present invention is led
The technical staff in domain can do various modifications or additions to described specific embodiment or replace in a similar way
Generation, but without departing from spirit of the invention or beyond the scope of the appended claims.
Although nut body 10, connecting cavity 11, chuck 12, grafting passage 13, Access Division 14, platform is used more herein
The terms such as rank portion 15, location division 16, snap ring 20, connection-peg 21, packing ring 22, spring 23, connection bolt 24, but be not precluded from using
The possibility of other terms.The use of these items is only for more easily describe and explain the essence of the present invention；Them
Any one of the additional limitations is construed to all to disagree with spirit of the present invention.
