Description
Technical field
The utility model belongs to technical field of buildings, relates to a kind of attaching nut for joint and clinging type link.
Background technique
The applicant pushes up in pile extension and prefabricated component [Authorization Notice No.: CN100348803C] in the patent of applying for before under spiral shell, by being positioned at, rising of pile tube two ends draws nut, top draws nut and pile tube longitudinal steel bar to form, wherein, rise and draw nut and top to draw nut to be female thread structure, described internal thread is for haling screw thread, Mao Di center has reinforced hole, and the periphery of reinforced hole is reinforcing bar end upset chuck, and the two ends upsetting of pile tube longitudinal steel bar becomes heading to be connected in chuck.This pile for prestressed pipe pile extension draws nut by rising, nut is drawn on top, combination sleeve, middle cover and connecting rod are formed, wherein, rise and draw nut and top to draw nut to be female thread structure, described internal thread is for haling screw thread, Mao Di center has reinforced hole, the periphery of reinforced hole is reinforcing bar end upset chuck, and the two ends upsetting of pile tube longitudinal steel bar becomes heading to be connected in chuck; Connecting rod one end is dentation structure, and the other end is external thread structure; Two panels or multi-disc combination sleeve are positioned at top and draw nut, be dentation structure and match with the dentation structure in connecting rod inside described combination sleeve; Middle cover is external thread structure, is screwed in top and draws nut interior and be positioned at two panels or multi-disc combination sleeve top; During docking, connecting rod one end draws the screw thread of nut to spin with rising, and the other end draws the two panels in nut or multi-disc to combine sleeve with top and forms clamping.
Docking calculation between this prestressing force prefabricated component, the end of two prefabricated components docked be respectively equipped with several rise draw nut and and several tops of corresponding draw nut, two panels or multi-disc combination sleeve are positioned at top and draw nut, middle cover is screwed in top and draws in nut and to be positioned on two panels or multi-disc combination sleeve, connecting rod one end with rise draw nut to spin, the other end and top draw the two panels in nut or multi-disc to combine sleeve to form clamping.
Above-mentioned top is drawn in nut and is provided with elastic component and combination sleeve, thus the connection with connecting rod can be realized, therefore elastic component and combination sleeve are absolutely necessary accessory, this configuration in actual use, need to lay, the steps such as positioning, must expend certain manpower, therefore needing when connecting to expend time in, connecting rod can not be realized and draw the quick of nut to be connected with top.
Model utility content
The purpose of this utility model is for the problems referred to above, provide a kind of easy to connect, efficiently for the attaching nut of joint and clinging type link.
For achieving the above object, the utility model have employed following technical proposal: a kind of attaching nut for joint and clinging type link, comprise nut body, described nut body has an annular chuck, and described annular chuck has the annular collar protruding from annular chuck.
In the above-mentioned attaching nut for joint and clinging type link, described annular collar is positioned on the lower surface of annular chuck, and the inwall of described annular collar and the inwall of annular chuck are on the same face.
In the above-mentioned attaching nut for joint and clinging type link, described annular chuck top has one in polygonal fixing column.
In the above-mentioned attaching nut for joint and clinging type link, described fixing column is quadrilateral or Hexagon.
In the above-mentioned attaching nut for joint and clinging type link, described annular chuck is inner and one end away from annular collar has a guide channel in inverted round stage taper, and it is inner that described guide channel is communicated with nut body.
Compared with prior art, the utility model has the advantage of: the utility model can realize being connected with the quick of connection-peg, and has locating function, when with connection-peg snap-fit engagement and, access section is connected firmly, and not easily loosens.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model provides;
Fig. 2 is the A place enlarged view of Fig. 1;
Fig. 3 is use principle figure of the present utility model.
In figure: nut body 1, annular chuck 2, annular collar 3, fixing column 4, guide channel 5, connection-peg 20, connecting end 21, bayonet end 22, clamping bar 23, inserted part 24, arc groove 25.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As depicted in figs. 1 and 2, a kind of attaching nut for joint and clinging type link, comprise nut body 1, described nut body 1 has an annular chuck 2, described annular chuck 2 has the annular collar 3 protruding from annular chuck 2, the cross section of annular collar 3 can be various shape, and preferably, the cross section of annular collar 3 is rectangle.
Annular collar 3 is positioned on the lower surface of annular chuck 2, and the inwall of described annular collar 3 and the inwall of annular chuck 2 are on the same face.Annular chuck 2 is inner and one end away from annular collar 3 has a guide channel 5 in inverted round stage taper, it is inner that described guide channel 5 is communicated with nut body 1, the effect of guide channel 5 to make connection-peg quick insertion, play leading role, even if nut body 1 docking with the unrealized position of connection-peg when connecting, also can realize connection-peg and being inserted in nut body 1.
Annular chuck 2 top has one in polygonal fixing column 4.Fixing column 4 is quadrilateral or Hexagon, and the effect of fixing column 4 is for coordinating the instruments such as spanner, for realizing location to nut body 1.
Working principle of the present utility model is: as shown in Figure 3, the utility model coordinates connection-peg 20 to use, the two ends of connection-peg 20 are respectively connecting end 21 and bayonet end 22, bayonet end 22 comprises the clamping bar 23 that several circumferences are evenly arranged, the end of clamping bar 23 has the inserted part 24 of expanding, inserted part 24 and annular chuck 2 can realize snap-fit engagement, inserted part 24 is provided with arc groove 25, arc groove 25 and annular collar 3 match, thus realize concavo-convex snap-fit engagement, play positioning action.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
