Description
Technical field
The utility model relates to the realm of building construction, particularly a kind of prestressed cable anchorage device.
Background technology
Prestress anchorage cable is the important support pattern of deep foundation pit support in building operations.There is crack in job site surrounding deep foundation pit road, building, even the security incident such as foundation pit collapse occurs repeatedly, and the accident wherein caused because of prestress anchorage cable defect occupies sizable ratio.In prestress anchorage cable practice of construction process, by the impact of place, environment, equipment and operator's level, prestress anchorage cable center line is difficult to control well with the concentric conllinear of ground tackle center line, and anchored end device non-directional slippage during prestress application, thus cause prestress anchorage cable and ground tackle center line to there is various angle and adjacent anchor fixed end to misplace the problem such as uneven, bring great difficulty to actual stretch-draw work.By adjusting the stretching force of tensioning equipment, easily cause the actual pre-applied force of prestress anchorage cable excessive or too small, can not ensure that on-the-spot practice of construction and Foundation Pit Support Design are theoretical consistent, bring potential safety hazard to foundation ditch, thus cause surrounding building and road to occur crack, even foundation pit collapse.
Conventional wedge way excavates a U-type groove on rectangle wedge shape iron block, and the processing of this wedge U-type groove is more difficult, and during construction, workman installs also more difficult, easily comes off; Or on circular wedge shape iron block, excavate a circular hole, the same perforate difficulty of the circular wedge shape iron block of this band cellular type, and during prestress application, counter-force face is little, and stress is concentrated serious.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of structure, effectively can improve the prestressed cable anchorage device of construction prestressed cable quality.
The purpose of this utility model is achieved through the following technical solutions: a kind of prestressed cable anchorage device, and it comprises waist rail, correcting wedge group, cover plate, steel strand and ground tackle; Described correcting wedge group comprises two correcting wedges be disposed on waist rail lateral surface, and the inclined-plane of each correcting wedge outwardly; The outer side of two correcting wedges is located at by described cover plate, is provided with the through hole holding steel strand and pass in the middle part of it; Described steel strand are fixed by ground tackle through after waist rail, correcting wedge group and cover plate successively.
Compared to prior art, the utility model has the advantage of:
1. by regulating waist depth of beam to make the level inclination of steel strand equal correcting wedge upper end acute angle, thus ensure that the center line of steel strand and the axis conllinear of ground tackle.
2. correcting wedge group is two correcting wedges be disposed on waist rail lateral surface, and steel strand, through two correcting wedges, without the need to digging hole, and do not contact between correcting wedge and steel strand, can not produce unnecessary frictional force.
3. waist rail arranges stiffening rib, stiffening rib and two correcting wedge contrapositions are arranged, and ensure that prestressing force power transmission is clearly clear, are also filled with concrete between two stiffening ribs of upside channel-section steel simultaneously, make channel-section steel both sides, upside stability when pressure-bearing stronger, strength and stiffness are larger.
4. be provided with some bracing frames on the downside of waist rail, bracing frame is for supporting fixing waist rail, correcting wedge group, cover plate and ground tackle, prevent its displacement from making the center line of steel strand and the axis not conllinear of ground tackle, and the gravity decreasing above-mentioned component is on prestressed impact.

Label declaration: 1 waist rail, 1-1 channel-section steel, 1-2 batten plate, 1-3 stiffening rib, 1-4 concrete, 2 cover plates, 3 steel strand, 4 ground tackles, 5 correcting wedges, 6 bracing frames.
Detailed description of the invention
Below in conjunction with Figure of description and embodiment, the utility model content is described in detail:
The embodiment schematic diagram of a kind of prestressed cable anchorage device provided for the utility model as shown in Figure 1 to Figure 3.
A kind of prestressed cable anchorage device, it comprises waist rail 1, correcting wedge group, cover plate 2, steel strand 3 and ground tackle 4; Described correcting wedge group comprises two correcting wedges 5 be disposed on waist rail 1 lateral surface, and the inclined-plane of each correcting wedge 5 outwardly; The two outer sides of correcting wedge 5 are located at by described cover plate 2, are provided with the through hole holding steel strand 3 and pass in the middle part of it; Described steel strand 3 are fixed by ground tackle 4 through after waist rail 1, correcting wedge group and cover plate 2 successively.
Described cover plate 2 processes for rectangular steel plates, and the hypotenuse of its length and correcting wedge 5 is isometric, and width is greater than spacing between two correcting wedges 5.
Described correcting wedge 5 is acute angle right-angled triangle.Described correcting wedge 5 should be processed according to practice of construction situation, two acute angles on it suitably can carry out chamfering cutting, make the hypotenuse of correcting wedge 5 smooth, be convenient to the angle adjusted between cover plate 2 and waist rail 1 and make it equal with the level inclination of steel strand 3, ensure that steel strand center line and ground tackle axis conllinear.
As shown in Figure 1, the triangle that steel strand 3, horizon and cover plate 2 forms and correcting wedge 5 have an acute angle equal, steel strand 3 and horizontal angle is highly made to equal another acute angle of correcting wedge 5 by regulating waist rail 1, the triangle that steel strand 3, horizon and cover plate 2 is formed and correcting wedge 5 are similar triangles, because correcting wedge 5 is acute angle right-angled triangle, so steel strand 3 perpendicular to cover plate 2, and then can ensure that steel strand 3 and the concentric conllinear of ground tackle 4 center line.
