The security incident of anchor.The method for handling anchor plate rupture is that steel wire bundle is moved back anchor, digs out broken concrete, polishes anchor plate
The concrete of surrounding, the steel plate of adequate thickness, steel plate central openings, steel wire bundle are passed through from perforate on pad.Meanwhile in steel plate
Injected hole is reserved at one jiao.Again steel strand beam, installation anchorage, tensioning, slip casting, sealing off and covering anchorage.Processing procedure and its cumbersome, and move back
Security incident easily occurs for anchor, and security risk is brought to construction personnel.
The content of the invention
The present invention provides a kind of Post-tension Prestress Construction anchor plate and its application method, at least to solve in tensioning
Anchor plate rupture often occurs in the process, pipeline caves in, collapses the problem of anchor accident.
According to an aspect of the present invention, a kind of Post-tension Prestress Construction anchor plate is provided, including being connected as one
Backing plate and cone, which is characterized in that on the anchor plate have it is multiple for steel strand beam, through backing plate and cone
The duct of overall length, also, the injected hole for being connected to the multiple duct is provided on the backing plate.
Preferably, there is a plurality of ribs on the outer wall of the cone.
Preferably, the cross section of the cone is circular or rectangle.
According to another aspect of the present invention, a kind of application method of Post-tension Prestress Construction anchor plate is provided, is wrapped
Include following steps：A. setting-out goes out the position of anchor plate in template, and anchor plate is fixed in template；B. by the loudspeaker of anchor plate
The miner diameter end of cylinder is connected with bellows, at blend compounds cloth sealed connection；C. spiral reinforcement is covered on the cone of anchor plate,
And it is fixed with stiffener；D. more steel wire bundles from bellows are penetrated and is pierced by from each duct of anchor plate.
Description of the drawings
By the way that embodiment is described with reference to accompanying drawings below, features described above of the invention and technological merit will become
More understand and be readily appreciated that.
Fig. 1 is the stereoscopic schematic diagram for the circular anchor plate of Post-tension Prestress Construction for representing the embodiment of the present invention；
Fig. 2 is the stereoscopic schematic diagram for the Post-tension Prestress Construction Flat shape anchor tie-plate for representing the embodiment of the present invention.
Specific embodiment
A kind of embodiment of Post-tension Prestress Construction anchor plate of the present invention described below with reference to the accompanying drawings.
Those of ordinary skill in the art will recognize, without departing from the spirit and scope of the present invention, can be with various
Different modes or its combination are modified described embodiment.Therefore, attached drawing and description are regarded as illustrative in nature,
It is not intended to limit the scope of the claims.In addition, in the present specification, attached drawing is drawn not in scale, and it is identical
Reference numeral represent identical part.
The present invention provides a kind of Post-tension Prestress Construction anchor plate, and Fig. 1 is the post stretching for representing the embodiment of the present invention
The stereoscopic schematic diagram of the circular anchor plate of pre-stress construction, including the backing plate 1 being connected as one and cone 2, cone 2
Bigger diameter end and backing plate 1 connect, and the miner diameter end of cone 2 can be connected in construction with bellows.Have in the center of backing plate 1 more
It is a that perpendicular to the duct of plate face 11, multiple ducts 11 pass through backing plate 1 and cone 2 with penetrating through, in Post-tension Prestress Construction,
The miner diameter end of cone is connected with bellows, the multiple steel wire bundles being pierced by from bellows are penetrated from the miner diameter end of cone
Multiple ducts 11 in anchor plate are pierced by the backing plate 1 of anchor plate.It is passed through in duct quantity and bellows in anchor plate
The quantity of steel wire bundle is identical.For example, if through 7 beam steel wire bundles, which uses 7 duct anchor pads in bellows
Plate, if using 11 duct anchor plates through 11 beam steel wire bundles, the anchor plate in bellows.The anchor plate uses multi-pore channel
Steel wire bundle structure so that will not be contacted between steel wire bundle, so as to avoid phase mutual friction, winding between steel wire bundle.Also,
Also there is injected hole 13, which penetrates backing plate 1 and extend to the position communicated with each duct 11 on cone.
After prestressed stretch-draw is carried out, vacuum grouting is carried out from injected hole 13.Also, in the surrounding of backing plate 1, also with multiple mounting holes
12, for anchor plate to be fixed on template.
In addition, on the outer wall of cone, there can also be the ribs for strengthening its structural strength, as shown in Figure 1, should add
Strong rib 22 is incorporated in strip on the outer wall of cone, and can be the outer wall that a plurality of ribs compartment of terrain is arranged in cone
On.
Fig. 2 is the stereoscopic schematic diagram for the Post-tension Prestress Construction Flat shape anchor tie-plate for representing the embodiment of the present invention, knot
Structure is similar with Fig. 1.Equally there is backing plate 3 and cone 4, only backing plate 3 and cone 4 are flat, similarly, backing plate 3
On also have multiple steel strand beams duct 31, duct 31 along backing plate length direction be distributed, and anchor plate have injected hole 33,
The injected hole 33 penetrates backing plate 3 and extends to the position communicated with each duct 31.On the outer wall of cone 4, also may be used
With with a plurality of ribs 42.
It is cavity inside the cone of anchor plate of the prior art, more steel wire bundles are easily rubbed, wound, and cavity
Structural strength it is weak.The cone of the multi-pore channel anchor plate is multi-pore channel entity structure, with shatter-resistant, resistance to compression, resistance to deformation
Ability, it is ensured that stretching method pre-stress construction quality, reduce construction personnel's security risk.
According to another aspect of the present invention, a kind of application method of Post-tension Prestress Construction anchor plate is provided, including
Following steps：
A. go out the position of anchor plate according to drawing setting-out in advance in template, anchor plate is fixed on by template by mounting hole
On, and ensure that its anchoring face is vertical with steel wire bundle.
B. the miner diameter end of the cone of anchor plate is connected with bellows, at blend compounds cloth sealed connection.
C. spiral reinforcement is covered on the cone of anchor plate, overlaps spiral reinforcement center line and anchor plate center line,
And it is fixed with stiffener.
D. more steel wire bundles from bellows are penetrated and is pierced by from each duct of anchor plate.That is, steel
Strand bundle is penetrated from one end of bellows, multiple ducts in the cone being connected by the other end with bellows, from backing plate
Place is pierced by.
After steel wire bundle lashing is completed, concreting is carried out, when concrete strength reaches the 90% of design strength,
Anchorage can be installed and carry out post-stressed tensioning, then, carried out very by the injected hole on anchor plate in design time
Pneumatics is starched, then cuts off the steel wire bundle more than length, is carried out concrete sealing off and covering anchorage, that is, is completed Post-tension Prestress Construction.
The Post-tension Prestress Construction anchor plate of the present invention is simple in structure, has preferable shatter-resistant, resistance to compression, resistance to deformation
Performance, it is ensured that construction quality and construction personnel safety.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should all be included in the protection scope of the present invention.
