Description
Technical field
It the utility model is related to a kind of prestress wire p-type anchor stopping means.
Background technology
As economic construction speed is accelerated, the increasing of communications and transportation road load, existing communications and transportation road is difficult to meet
Transport capacity required for growing economic pace, therefore there is large-scale construction of road and bridge, it is particularly some large spans
Bridge sets up thee-direction prestressed system, i.e. longitudinal prestressing, vertical prestressing, transverse prestress.Among three kinds of prestressing force, erect
To prestressing force, transverse prestress frequently with one-end tension mode, it is necessary to use p-type extruding anchor.The p-type anchor of 0VM companies production
Tool is divided into fixing end p-type anchorage according to the difference of structure type and fixing end justifies p-type anchorage.P-type Extrusion anchor ground tackle is in steel strand wires
Head puts extruded sleeve, is extruded by special-purpose machines and tools so that extruded sleeve bonds steel strand wires after producing plastic deformation and clamped, and steel twists
A relay for line passes to component by extruded sleeve by special backing plate.Due to its inconvenient tensioning, therefore frequently as fixing end anchorage
Used.At present prestressing force p-type extruding anchor construction among, typically directly by spacer dimple pipe, constraint circle and spiral bar,
Fixed anchor slab and the steel strand wires with extrusion head are assembled according to certain order, and are fixed between anchor slab and extrusion head not
Have and reliably connect, it is impossible to ensure that extrusion head closely presses close to fixed anchor slab, it will serious quality results are brought, such as because between
Local Cracking destruction etc. is caused away from inadequate.
To sum up, the problem of p-type anchorage generally existing the following aspects used at present：1) between constraint circle and fixed anchor slab
Mounting distance can not meet the requirement of parameter B (min) in technical requirements；2) install rear p-type anchor extrusion head and fixed anchor slab it
Between be loose, generally have one section of distance, it is impossible to meet the purpose being close in specification.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of prestress wire p-type anchor stopping means.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is, for prestress wire p-type anchor
Stopping means, including fixing end anchor slab, extrusion head, banking stop and caging bolt；Banking stop passes through caging bolt and fixing end p-type
The fixing end anchor slab of anchorage is connected and fixed, and by extrusion head limitation positioned at the space between fixing end anchor slab and banking stop
It is interior.
Preferably, banking stop is circular or square stalloy, the stalloy is provided with caging bolt mounting hole site.
Preferably, extrusion head produces plastic deformation by the steel strand wires for putting extruded sleeve by special-purpose machines and tools extruded sleeve
After bond steel strand wires and formed.
The beneficial effects of the utility model are：
Simple in construction, reasonable in design, easy for construction and construction cost is low, good mechanical performance, using effect are good, Neng Gouyou
Gap is big between the existing p-type extruding anchor fixing end anchor slab of effect ground solution and extrusion head, it is not close to connect, and fixing end anchor slab is without constraint
The various problems such as slidably.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural representation of the utility model prestress wire p-type anchor stopping means embodiment.
Marked in figure：1- bellowss, 2- spiral bars, 3- constraint circles, 4- grout outlets, 5- steel strand wires, 6- fixing end anchor slabs, 7-
Extrusion head, 8- banking stops, 9- caging bolts.
Embodiment
Fixing end p-type anchorage is by bellows 1, spiral bar 2, constraint circle 3, grout outlet 4, extrusion spring and extruding set group
Into.
Extruded by special-purpose machines and tools, extruded sleeve forms extrusion head 7 in the front end of the steel strand wires 5 of fixing end p-type anchorage.
As shown in figure 1, when mounted, limited bit slice 8, caging bolt 9 are refilled on the basis of fixing end p-type anchorage.
Banking stop 8 is made of the thick stalloys of 1~2mm, and cuts into and meets size, is cut in middle correct position
Pore-forming.Caging bolt 9 is diameter about 5mm, length about 8cm slender bolt.Banking stop 8 is arranged on fixing end P during installation
The front end of the extrusion head 7 of type anchorage, and it is fixed on fixing end p-type anchor after passing through the mounting hole on banking stop with caging bolt 9
On fixing end anchor slab 6 so that extrusion head is between fixing end anchor slab and banking stop.
The construction method of prestress wire fixing end p-type anchor stopping means, specifically includes following steps：
(1) extrusion spring and extruded sleeve are covered respectively on the head of steel strand wires first, and extruded sleeve is mounted in the end of steel hinge line 5
Portion；
(2) steel strand wires for putting extruded sleeve are extruded with special-purpose machines and tools, extruded sleeve is bonded steel strand after producing plastic deformation
Line and form extrusion head.When being pressed through extrusion die, MTP value is between 25~35MPa, it is desirable to bottom and steel strand wires
Nesting should be closely entirely embedded between extruded sleeve and steel strand wires without pit, extrusion spring, and length and external diameter should after extruding
Meet producer's set-point, outside is answered smooth flawless.
(3) it is fixing end p-type anchorage is assembled successively according to Fig. 1 examples；
(4) spacer dimple pipe 1, constraint circle 3 and spiral bar 2 are installed, the steel strand wires 5 for having extruded extrusion head penetrated successively solid
Mounting hole site on fixed end anchor slab 6, and by steel strand wires are single or whole beam passes through bellows, installation are had good positioning fixing end anchor slab；
(5) stopping means is installed, banking stop 9 is arranged on p-type anchor end successively, and is fixed with caging bolt 8, really
The mounting distance protected between constraint circle 3 and fixing end anchor slab 6, which must is fulfilled for installation specification and extrusion head, should be close to fix
Hold anchor slab；
(6) finally grout outlet 4 is installed in position and carries out channel seal, in case spillage enters during casting concrete
Enter bellows 1.
Compared with prior art, the present embodiment has advantages below：
1. simple in construction, reasonable in design and construction cost is relatively low.
2. it is good from heavy and light, stress performance, it is not tight to can effectively solve the problem that current p-type extruding anchor fixation anchor slab connects with extrusion head
It is close, apertured problem.
3. easy for construction and using effect is good, the acquisition easy to process of the sheet metal required for the present apparatus.
4. pair original device not damaged, it is only necessary to which newly-increased feeder apparatus is reliably connected slender bolt.
5. it is applied widely, transverse prestress, the p-type extruding anchor of vertical prestressing of one-end tension can be effectively applicable to
In work progress.
The present embodiment is fixed p-type anchor end to prestress wire using stopping means and limited, it is easy to so that about
Mounting distance meets installation specification between beam circle and fixing end anchor slab, and allows extrusion head closely to press close to fixed anchor
Plate so that work efficiency is improved significantly, and construction cost is controlled very well.
Above-described the utility model embodiment, does not form the restriction to scope of protection of the utility model.It is any
Made within spirit of the present utility model and principle modifications, equivalent substitutions and improvements etc., should be included in the utility model
