Description
Technical field
The utility model is related to technical field of building construction tools more particularly to a kind of construction paddle type mill expansible anchors
Nail.
Background technology
The place that building field is related to the anchoring of wall, furred ceiling, ground and other construction materials is relatively more, here greatly
Part uses rivet and setscrew, technology also comparative maturity, but in some fields, anchoring effect is simultaneously bad, respectively has
Its advantage and disadvantage, but operate all comparatively laborious, these anchoring pieces have the limitation of its specific area, need to research and develop and a kind of using field
Extensively, operating process is simple, the good anchoring piece of anchoring effect, and the utility model provides a kind of construction paddle type mill expansible anchor
Nail has good anchoring effect and shirtsleeve operation flow.
Utility model content
The purpose of this utility model is to provide a kind of construction paddle type mill bolts, have good anchoring effect with
And shirtsleeve operation flow.
To achieve the goals above, the utility model adopts the following technical solution：
A kind of construction paddle type mill bolts, including a cylindricality rivet nut, a cylindrical plug pin, under the rivet nut
Portion is sharp cone, is tufted by anchoring piece convenient for rivet nut, there are one section of cylinder type hollows for cylindricality rivet nut center
Area, the cylindrical empty heart district extend to rivet nut lower area, and cylindricality rivet nut stage casing region surrounding is provided with and column
The raised anchor slab that staple body is integrated, in the state that plug pin is not stuffed into, the protrusion anchor slab inner side edge is inwardly protruding, outside
Side is then in same plane with rivet nut lateral surface, and the straight of plug pin is smaller than between the raised anchor slab inside in the rivet nut
Diameter, the use operating method of the construction paddle type mill bolts are first to hammer into the hammering of cylindricality rivet nut by anchoring piece, by
It is in same plane with cylindricality rivet nut outer side edges in the outer side edges of raised anchor slab at this time, then raised anchor slab will not be to cylindricality rivet nut
Generation interference is hammered into, cylindricality rivet nut can be hammered into smoothly, and after cylindricality rivet nut is tufted into, plug pin is inserted into the sky of cylindricality rivet nut
Heart district domain is simultaneously hammered into, and at this time due to the diameter for being smaller than plug pin between the inner side edge of raised anchor slab, is followed closely by plug pin
Fashionable contact and extruding by plug pin, raised anchor slab can be formed to by the fixation of anchoring piece, and plug pin outwardly against expansion
It is moment to hammer into the power to be formed, and impact force is strong, the firm knot degree height of anchoring, and construction process is simple, and it is few to be disturbed factor, applies
Work speed is fast.
Further, the outer side edges of the raised anchor slab are handled using feather plucking, can be increased when with being contacted by anchoring piece
Frictional force improves anchoring strength.
Further, cylindricality rivet nut top surrounding is provided with otic placode, be used for fixed column staple body position, avoid by
It further hammers to be absorbed in by anchoring piece.
Further, plug pin top surrounding is provided with otic placode, the position for fixing plug pin, avoids further being hammered into shape
Enter.
Further, it is provided with washer below the otic placode edge surrounding of plug pin top surrounding, it can be to entire cylindricality
Covering is formed at rivet nut top, increases globality, improves aesthetic effect.
Description of the drawings
Fig. 1 is the cross section structure schematic diagram before the hammering of the utility model embodiment plug pin anchors into.
Fig. 2 is the effect cross section structure schematic diagram after the hammering of the utility model embodiment plug pin anchors into.
Specific implementation mode
The utility model is described in detail below in conjunction with specific implementation mode.
As shown in Figure 1, a kind of construction paddle type mill bolts, including a cylindricality rivet nut 1, a cylindrical plug pin
2,1 lower part of the rivet nut is sharp cone, is tufted by anchoring piece convenient for rivet nut 1, there are one section for 1 center of the rivet nut
Cylindrical empty heart district 12, the cylindrical empty heart district 12 extend to 1 lower area of rivet nut, 1 stage casing region four of the rivet nut
Be provided with the raised anchor slab 13 being integrated with rivet nut 1 week, the section in figure because 13 lower section of raised anchor slab is not attached to rivet nut 1,
So be shown as off-state, practical entire rivet nut 1 is an entirety, is not off-state, there is no raised anchor slabs 13
Region is integrated up and down, figure middle section be indicate for convenience raised anchor slab 13 there are effects；It is not stuffed into plug pin 2
In the state of, protrusion 13 inner side edge 131 of anchor slab is inwardly protruding, and outer side edges 132 are then in same flat with 1 lateral surface of rivet nut
Face, the diameter for being smaller than plug pin 2 between 13 inside of raised anchor slab in the rivet nut 1, construction paddle type mill expansion
The use operating method of holdfast is first to hammer into the hammering of rivet nut 1 by anchoring piece, due to the outer side edges 132 of raised anchor slab 13 at this time
It is in same plane with 1 outer side edges of rivet nut, then raised anchor slab 13 will not hammer into generation interference to rivet nut 1, and rivet nut 1 can be suitable
Profit hammers into, and after rivet nut 1 is tufted into, plug pin 2 is inserted into the hollow area of rivet nut 1 and is hammered into, at this time due to raised anchor slab
The diameter for being smaller than plug pin 2 between 13 inner side edge 131, when being hammered by plug pin 2 by the contact and extruding of plug pin 2,
Raised anchor slab 13 can be formed to by the fixation of anchoring piece outwardly against expansion, as shown in Fig. 2, and plug pin 2 hammer into the power to be formed
It it is moment, impact force is strong, the firm knot degree height of anchoring, and construction process is simple, is disturbed that factor is few, and speed of application is fast.
Further, the outer side edges 132 of the raised anchor slab 13 are handled using feather plucking, can be with when with being contacted by anchoring piece
Increase frictional force, improves anchoring strength.
Further, 1 top surrounding of the rivet nut is provided with otic placode 14, the position for fixing rivet nut 1, avoids by into one
Step hammers to be absorbed in by anchoring piece.
Further, 2 top surrounding of the plug pin is provided with otic placode 21, the position for fixing plug pin 2, avoids by into one
Step hammers.
Further, it is provided with washer 22 below the 21 edge surrounding of otic placode of 2 top surrounding of the plug pin, it can be to entire
Covering is formed at cylindricality rivet nut top, increases globality, improves aesthetic effect.
