Abstract
The utility model discloses a guiding cap for a pressure type anchorage cable end socket. The key point is that the guiding cap comprises a base provided with a through hole (1) for a steel strand (6) to penetrate through, and a pushing cap buckled with the base, a groove (2) for placing a bearing plate (7) is arranged inside the base, and a groove (5) for placing a P anchor (8) is arranged inside the pushing cap. The guiding cap adopting the structure is convenient for construction and anchorage, can guarantee that the dynamic behavior of pressure-type anchors can be fully exerted.
Description
Technical field
The utility model relates to geotechnical engineering prestressed anchorage technology field, relates in particular to the guiding cap that is used for anchor cable is imported smoothly anchor hole in a kind of pressure-type prestress anchorage cable.
Background technology
The prestress anchorage cable technology is one of technology the most frequently used in the geotechnical engineering, is widely used in slope anchorage, fields such as pattern foundation pit supporting structure.The pressure-type anchor cable is a kind of in the prestress anchorage cable technology, mainly is made of mortar anchoring body, ground tackle, non-bending steel cable, loaded plate and P anchor.During work, the stretching force of pressure-type anchor cable is directly delivered to the P anchor by non-bending steel cable, by P anchor roof pressure loaded plate, pass to the mortar anchoring body again, by mortar power is delivered in the stable rock-soil layer, plays the reinforcement effect of stablizing the geotechnical body surface structures or unstable geotechnical body and stable geotechnical body being linked together.Compare with traditional tension type anchor cable, the pressure-type anchor cable has the bearing capacity height, be out of shape little, good endurance, characteristics such as ductility is good.But, can run into bigger difficulty when the pressure-type anchor cable construction casts anchor.Because the loaded plate of front end and P anchor are heavier, when casting anchor, the front end tenesmus is stuck in the rough hole wall easily.When small stair that the intersection by soil layer conduit and petrosal foramen forms, easier blocking.Cast anchor by force and can cause the loaded plate reach, separate with the P anchor, the pressure-type anchor cable stress performance of Xing Chenging is bad like this, very big displacement will occur under little pulling force, and the essence of this displacement is that the P anchor moves forward again to withstand loaded plate under the stretching force effect.Traditional anchor cable guiding cap adopts thin steel bar to make, and several thin steel bars is intersected be bent to form head taper guide frame, need be with welding machine with steel strand and guiding cap welding during use.This guiding cap trouble of not only constructing, and the fuel factor of welding portion can influence the mechanical property and the application life of steel strand.The more important thing is, when this traditional direction cap is used in the pressure-type anchor cable, can not overcome the above-mentioned construction difficulty of casting anchor well.
Summary of the invention
The purpose of this utility model is the guiding cap that a kind of convenient construction of design, assurance pressure-type anchor cable mechanical property are given full play to.
To achieve these goals, the utility model is by the following technical solutions: a kind of guiding cap that is used for pressure-type anchor cable termination, it is characterized in that: it comprises base with the through hole that passes through for steel strand and the top cap that is interlocked with base, the inboard of described base is provided with the groove of placing loaded plate, and the inboard of described top cap is provided with the groove of placing the P anchor.
Have buckle on the described base, the outer end of described buckle takes the shape of the letter U and has barb; Described top cap is provided with the draw-in groove that matches with described buckle.
In order to make more firm being fixed on the base of buckle, the other end of described buckle also has flanging.
Stressed for fear of connecting portion and hole wall excessive friction, the coniform waist of described top cap slightly outwards bloats.
In order to save material and weight reduction, the rear end of described top cap has cavity.
The beneficial effects of the utility model:
(1) convenient construction.Base adopts buckle with being connected of top cap.Only need during construction the Connection Card on the base is snapped in draw-in groove corresponding on the cap of top, convenient and swift, the reliability height.Base and top cap form the taper smooth surface in connecting into after the integral body loaded plate and P anchor being wrapped in fully, and the smooth camber line of front end can help the hole wall by injustice, and making casts anchor becomes easy.
(2) adherence pressure type anchor cable mechanical property. by on the base and the groove of top cap upper limit, loaded plate and P anchor just are stuck in base and cap inside, top, and applying is tight, can not move forward and backward, when preventing anchorage cable stretching because of big displacement occurring loaded plate and separating of P anchor.

The specific embodiment
Below in conjunction with accompanying drawing embodiment is done specific description.
Embodiment: as Fig. 1 to shown in Figure 8, a kind of guiding cap that is used for pressure-type anchor cable termination, it comprise base with the through hole 1 that passes through for steel strand 6 and with the top cap that base is interlocked, have buckle 3 on the base, the outer end of buckle 3 takes the shape of the letter U and has barb; Buckle 3 can adopt metal material, has intensity preferably like this.The inboard of base is provided with the circular groove 2 of placing loaded plate 7; The top cap is provided with the draw-in groove 4 that matches with buckle 3, and the inboard of top cap is provided with the circular groove 5 of placing P anchor 8.Groove 2 and groove 5 play the position-limiting action to loaded plate and P anchor.Groove 5 can be set to one makes loaded plate 7 be subjected to the extruding of cap bottom surface, top than the smaller circular groove of groove 2 radiuses, does not rock thereby just in time be fixed in the circular groove 2 of base inboard.The other end of buckle also has flanging 31, has strengthened the part that is buckled in the base like this, has guaranteed fastness better.The top cap is coniform, and the coniform waist of top cap slightly outwards bloats.Avoid connecting portion and hole wall excessive friction stressed and damage.The rear end of top cap has cavity 9, has reduced material, has saved expense.
Guiding cap can adopt the engineering plastics monobloc cast to make, and metal buckle 3 is embedded in when building in the base, has guaranteed enough bonding strengths.During use, steel strand 6 are passed respective through hole 1 on the base, pass loaded plate 7 again, extruding P anchor 8 is made enlarged footing, allows P anchor 8 compress loaded plate 7, and P anchor 8 and loaded plate 7 surfaces are done preservative treatment, smear anticorrosion ointment, wrap up anticorrosion cloth, again loaded plate 7 is withstood the circular groove 2 in the base.Put the top cap, metal clamps 3 correspondences are snapped in metal draw-in groove 4, guarantee that connection is fastening, P anchor 8 withstands the circular groove 5 in the cap of top automatically at this moment, and whole P anchor and loaded plate are fixed in the guiding cap, do not rock.Key position to power transmission has carried out anti-corrosion treatment, improves the durability of anchor cable.
Below reach embodiment in conjunction with the accompanying drawings the utility model has been done detailed description, but do not form restriction of the present utility model, the modifications and variations that all drop in the utility model claim protection domain all drop within the protection domain of the present utility model.
