Specific embodiment
Further to illustrate that the utility model is to reach the technological means and effect that predetermined goal of the invention taken, below
With reference to attached drawing and preferred embodiment, to according to the utility model proposes its specific embodiment, structure, feature and its effect,
It is described in detail as after.
It referring to Fig. 1, a kind of aligning stops sizing device, can both match, can also be answered with Two-way with common bolt
Power anchor rod-matched uses, and plays the role of adjusting anchor rod prestress center of gravity, only starch.The aligning stops sizing device and includes being sequentially sleeved at
Aligning stop grouting plug 2, aligning grout cover plate 1 and opening nut 3 on anchor pole, wherein aligning grout cover plate 1 and aligning stop grouting plug 2
It is the cavity structure of three-stage.
As shown in Figures 2 and 3, aligning grout cover plate 1 is included in the first round table-like osculum end 11, the first big opening end 13
And the First Transition section 12 of both connections, and wall thickness is equal everywhere.Preferably, aligning grout cover plate 1 is added by seamless steel pipe
Work forms, and when being used cooperatively with common bolt, the inner cavity of First Transition section 12 can make as the cavity of reacting cycle grouting device
With.
As shown in Figure 4 and Figure 5, aligning stop grouting plug 2 include in the second osculum end 21 of circular platform type, the second big opening end 23 and
Both connections and the second cylindrical changeover portion 22.The inner wall at wherein the second osculum end 21 is cylindrical, and aligning can be made only to starch
Plug 2 is firm to be set on anchor pole A.The internal diameter at the second osculum end 21 is equal with the diameter of anchor pole A or slightly larger than bolt diameter,
The internal diameter at the second osculum end 21 is less than the internal diameter of the second changeover portion 22.Preferably, aligning stop grouting plug 2 is by flexible rubber material
Material is process, and the maximum outside diameter of the second big opening end 23 is slightly larger than the diameter in palisades hole, is made in the promotion of aligning grout cover plate 1
Under, aligning stop grouting plug 2 is due to having elastic then collapsible and holding at palisades hole so that aligning grout cover plate 1 and aligning
Palisades hole can be closed during 2 cooperating of stop grouting plug tight.
As shown in Figure 6 and Figure 7, the end face of the opening nut 3 forms cambered surface 31, and on the end face after carrying out fillet processing
Offer several rectangular channels 32.The internal thread of opening nut 3 matches with anchor pole external screw thread.Preferably, opening nut 3 is six
Angle nut, the quantity of rectangular channel 32 is six.
During work, aligning stop grouting plug 2, aligning grout cover plate 1 and opening nut 3 are sequentially sleeved at the tail end of anchor pole A, then
Rotation opening nut 3 simultaneously makes it screw in First Transition section 12, and the opening nut 3 is when screwing, 31 and first mistake of cambered surface
The inner wall for crossing section 12 pushes against, and then the inner wall of the outer wall and the second big opening end 23 of First Transition section 12 is made closely to interlock.
Specifically, the endoporus minimum diameter at the first osculum end 11 is consistent with mating anchor bolt A diameters, can stablize
It is set on anchor pole.Second big opening end, 23 inner wall taper and the outer wall taper of First Transition section 12 match, so that the two is in phase
Interior realization closely interlocks when detaining and compressing, and mortar spill and leakage comes out during playing the role of preventing slip casting.And the first osculum end 11
Maximum outside diameter is less than the diameter in palisades hole, can adjust the anchoring prestressed center of gravity of product, solve existing common backing plate bearing capacity
Non-uniform problem.It is common backing plate carrying that the structure of aligning grout cover plate designed by the utility model, which so that it carries prestressing force,
More than twice of power, and prevent backing plate from being deformed in high-pressure slip-casting.
Importantly, what is installed in the inner cavity of First Transition section 12 is opening nut 3, the nut of the special construction is in precession
When, the end face where rectangular channel 32 can mutually be shunk, and more revolve more tighten under the extruding force of 12 inner wall of First Transition section, be had
There is auto-lock function, extremely strong fixed function can be played.When in normal construction and constantly carrying out slip casting to middle spare anchor bar in addition, need
There is the slurry exhaust outlet that overflows to be used to exclude the gas in palisades hole and anchor pole A, slurry could be noted in this way, then rectangular channel 32 just rises
The effect of excessive slurry exhaust is arrived.Since slurry can solidify in a short time, and if see that slurry overflows on a small quantity from rectangular channel 32
When just stop slip casting at once, then be not in the situation that slurry is largely overflowed from rectangular channel 32, therefore really a large amount of stifled slurries are gone back
It is aligning stop grouting plug 2 and aligning grout cover plate 1.
Utility model works principle is as described below：
Referring to Fig. 1, in construction, anchor pole A and anchor drill bit are placed in the palisades hole accomplished fluently, until anchor drill bit and
Anchor pole reaches scheduled position together, and the first osculum end 11 of aligning grout cover plate 1 is buckled into the second largest mouth of aligning stop grouting plug 2
End 23, and 12 outer wall of First Transition section is made to be bonded with 23 inner wall of the second big opening end, the first osculum end 11 is located at the second transition at this time
In section 22.Then aligning stop grouting plug 2 and aligning grout cover plate 1 are installed to the tail end of anchor pole A, while can only be starched with rotary aligning
Backing plate 1 adjusts center of gravity, then 2 holding of aligning stop grouting plug is blocked up sternly in palisades hole until by palisades hole.It will be open with spanner later
Nut 3 is mounted on the anchor pole in First Transition section 12, continues rotation locking, aligning grout cover plate 1 and aligning stop grouting plug 2
Even closer is interlocked, to prevent mortar spill and leakage, since 23 maximum outside diameter of the second big opening end is more than palisades bore dia, is then being revolved
The inlet in palisades hole mutually compresses to realize sealing with 23 outer wall of the second big opening end when tight.Finally start to anchor pole A slip castings.
The above descriptions are merely preferred embodiments of the present invention, and any person skilled in the art is not
It is detached from the range of technical solutions of the utility model, according to the technical essence of the utility model any letter made to the above embodiment
Single modification, equivalent variations and modification, in the range of still falling within technical solutions of the utility model.
