Abstract
The utility model discloses a P-type anchorage device at a fixed end. The P-type anchorage device comprises an extrusion anchor, an anchoring base plate, a steel strand, spiral bars, a slurry outlet pipe, a constraint ring and a corrugated pipe, wherein one end of the steel strand sequentially penetrates through the corrugated pipe and the constraint ring, and the other end of the steel strand is sequentially connected with the anchoring base plate and the extrusion anchor and is anchored; the constraint ring and the slurry outlet pipe are arranged on the steel strand which penetrates through the corrugated pipe; the spiral bars are arranged outside the constraint ring; the P-type anchorage device also comprises an anchorage device open sleeve and a retaining ring; the anchorage device open sleeve is arranged between the anchoring base plate and the extrusion anchor; the retaining ring is arranged at the rear end of the anchoring base plate. The utility model aims to solve the problems of manufacturing of the extrusion anchor in a narrow space and overall placement of the manufactured anchoring base plate and a prestressed cable in the case with effective prestressed application length. According to the P-type anchorage device, the construction difficulty of the P-type anchorage device at the fixed end in a narrow manufacturing space is reduced, the working efficiency is improved, the construction quality is improved, and the effective prestressed length of the member is increased.
Description
Technical field
The utility model relates to prestressed anchor, refers to particularly a kind of fixed end P type ground tackle.
Background technology
For the continuous cast-in-place one-end tension member of many Pin, for improving effective prestress, apply length, the making space of fixed end P type ground tackle is often narrower and small, for the conventional way of this problem for bellows to be just installed after the colligation of member outer reinforcement and to reeve from stretching end, when being made extruding anchor by pull end, bellows must be divided and make two joints, wherein fixed according to field fabrication space requirement by pull end one joint length, this joint is bigger compared with another joint, before making, extruding anchor will by rotation, be entangled another joint by pull end bellows, after making extruding anchor, integral body is drawn to design attitude location by anchor plate and prestressed cable, and then rotate by pull end bellows to design attitude, difficulty of construction is larger, major embodiment is in the following areas:
(1) owing to making the needs in space, before extruding anchor is made, anchor plate is generally positioned at inclined to one side stretching end one side of design attitude, after extruding anchor completes, need integral body to drag anchor plate and prestressed cable to design attitude, the long rope more to radical, pulls difficulty larger, efficiency of construction is low, easily causes bellows skew simultaneously.
(2), when by pull end plain bars comparatively dense, integral body drags anchor plate and prestressed cable can cause the skew of already installed plain bars position, need to adjust plain bars, increases workload.
(3) existing P type ground tackle is owing to making narrow space, and after moulding, quality is difficult for guaranteeing, affects anchoring property.
For the continuous cast-in-place one-end tension member of many Pin, in the situation that guaranteeing effective prestress application length, for reducing difficulty of construction, increase work efficiency, just need to solve extruding anchor in small space make and complete after anchor plate and the Integral in-position problem of prestressed cable.
Summary of the invention
The purpose of this utility model is to overcome the weak point of above-mentioned existing background technology, and provide the fixed end P type ground tackle of a kind of easy construction and stable performance, with in the situation that guaranteeing effective prestress application length, solve extruding anchor in small space make and complete after anchor plate and the Integral in-position problem of prestressed cable.
The purpose of this utility model reaches by following technical solution: fixed end P type ground tackle, it comprises extruding anchor, anchor plate, steel strand, spiral bar, outlet pipe, constraint circle, bellows, one end of described steel strand is successively through bellows and constraint circle, the other end of steel strand is connected with extruding anchor with anchor plate and anchoring successively, through being provided with constraint on the steel strand of bellows, enclosing and outlet pipe, constraint circle outside is provided with spiral bar, its special character is, it also comprises ground tackle opening sleeve and clasp, between described anchor plate and extruding anchor, be provided with ground tackle opening sleeve, the rear end of described anchor plate is provided with clasp.
As preferred version, described ground tackle opening sleeve is two lobe formulas.
Further, described clasp is C type clasp.
The utility model has been realized disposable making and the location of prestress anchorage cable fixed end P type ground tackle, thereby simplifies working procedure and difficulty, saves the duration; Before making, ground tackle can carry out the making of extruding anchor, avoid at narrow space and the intensive fixed end operation extruder construction extruding anchor of reinforcing bar, thereby the difficulty of construction while having reduced the continuous one-end tension site concrete of many Pin fixed end P type ground tackle making narrow space, increase work efficiency, improved workmanship; Can by fixed end P type ground tackle to greatest extent near member by pull end, performance is more stable, has increased the effective prestress length of member simultaneously.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in the figure, the utility model comprises extruding anchor 4, anchor plate 2, steel strand 5, spiral bar 6, outlet pipe 7, constraint circle 8, bellows 9, one end of described steel strand 5 is successively through bellows 9 and constraint circle 8, the other end of steel strand 5 is connected with extruding anchor 4 with anchor plate 2 and anchoring successively, through being provided with on the steel strand 5 of bellows 9, retraining circle 8 and outlet pipe 7, constraint circle 8 outsides are provided with spiral bar 6, it is characterized in that, it also comprises ground tackle opening sleeve 3 and clasp 1, between described anchor plate 2 and extruding anchor 4, be provided with ground tackle opening sleeve 3, the rear end of described anchor plate 2 is provided with C type clasp 1.Wherein, described ground tackle opening sleeve 3 is two lobe formulas.
During use, after the colligation of member outer reinforcement completes, bellows 9 is installed, the subsidiary steel strand 5 of having made extruding anchor 4 is passed to bellows 9, and put constraint circle 8 and spiral bar 6.Accurately location and installation anchor plate 2, drags steel strand 5 and extruding anchor 4 is passed to anchor plate 2 by root.Ground tackle opening sleeve 3 is installed, is utilized C type retaining ring tongs C type clasp 1 to be installed with fixing ground tackle opening sleeve 3, by root, adjust steel strand 5 and make extruding anchor 4 near ground tackle opening sleeve 3.Constraint circle 8 and outlet pipe 7 are installed.Binding structural member internal layer reinforcing bar, concreting, maintenance tension steel strand 5, carry out vacuum grouting to bellows 9.Described steel strand 5 are through extruding anchor 4, ground tackle opening sleeve 3, anchor plate 2, C type clasp 1, spiral bar 6, constraint circle 8 and bellows 9.Described steel strand 5 are formed and are reliably connected by special extruder extruding with extruding anchor 4.Perforate on described anchor plate 2 is because the use of ground tackle opening sleeve 3 is large compared with conventional anchor backing plate.Described ground tackle opening sleeve 3 is two lobe formulas, through fixing by C type clasp 1 after anchor plate 2.Described steel strand 5 are after tension, and by vacuum grouting process, being in the milk to be sealed in is applied in prestressed member.In addition, all component is all embedded in concrete.
