Abstract
The utility model relates to a free-type pull-pressing compound prestressed anchor cable which is composed of a guide cap, a supporting plate, an anchor plate, an extrusion head, screw bolts, an isolating shelf, a constraint loop, a grout pipe, non-binding steel strands, and anchor tool, wherein, the anchor plate and the extrusion head are matched and combined with non-binding steel strands into an integral through extruding. The supporting board and a plurality of extruded integrals are connected in series into integration through screw rods to compose pressure type strand bundles, and thus, the part of anchoring portion is not only provided with pull type strand bundles but also provided with pressure type strand bundles. The free-type pull-pressing compound prestressed anchor cable, the prestressed force distribution of which is nearly homogeneous is formed from weaving and processing the pull type strand bundles and the pressure type strand bundles.
Description
The utility model relates to a kind of prestress anchorage cable.
Existing prestress anchorage cable has tension type prestress anchorage cable and pressure-type prestress anchorage cable.The anchoring section leading portion of tension type prestress anchorage cable is stressed to be the tensile stress concentration zones, and gradually to back segment and easily produce shear failure, the anchoring section latter end of pressure-type prestress anchorage cable is stressed be the compressive stress concentration zones, also easily causes pressure break to leading portion gradually.The two all can have a strong impact on the prestress anchoraging effect to the different failure mode of anchoring section.
In view of the foregoing, the purpose of this utility model is to remove anchoring section stress concentration distribution situation, designs a kind of stress distribution and is tending towards evenly, the compound prestress anchorage cable of the tension and compression that anchoring effect is good.
The utility model has reached above-mentioned purpose preferably, it is by guiding cap, supporting plate, anchor slab, extrusion head, bolt, isolating frame, the constraint circle, grout pipe, ground tackle and nothing bonding steel streakline constitute, supporting plate, anchor slab, isolating frame is central authorities and porose plectane all around, anchor slab, extrusion head and non-bending steel cable become whole through extruding, and whole of supporting plate and several extruding is chained together by screw rod, form pressure-type streakline bundle, with isolating frame, the tension type twisted wire bundle that constraint circle and non-bending steel cable constitute is organized in together, make anterior pressure-type twisted wire bundle of anchoring section and tension type twisted wire Shu Yingli stack, evenly distribute, guiding cap and supporting plate foremost are connected, and do not have bonding, ground tackle on steel strand end and the anchor pier is connected, grout pipe penetrates from the anchor cable end, and through confinement tube, isolating frame and whole through pressure-type twisted wire bundle of extruding be the guiding cap place foremost.
The utility model is designed to pressure-type twisted wire bundle with the anchoring section front portion, and whole anchoring section has tension type twisted wire bundle, with the two establishment processing together, compressive stress and tensile stress stack, guaranteed that stress distribution is even, thereby prolonged the application life of anchor cable greatly, and obviously improved the slope reinforcement effect.Handle if it is widely used in the slope reinforcement of engineerings such as water power, railway, highway, strong assurance will be provided the safe operation in aforementioned field surely, and will have a tremendous social and economic benefits thus.
Further specify the utility model below in conjunction with accompanying drawing:
Fig. 1 is the compound prestress anchorage cable structural representations of this free style tension and compression.
The compound prestress anchorage cable of this free style tension and compression, constitute by guiding cap 1, supporting plate 2, anchor slab 3, screw rod 4, extrusion head 5, steel strand 6, isolating frame 7, constraint circle 8, anchor pier 9, backing plate 10, ground tackle 11 and grout pipe 12, supporting plate 2, anchor slab 3, isolating frame 7 are central authorities and porose plectane all around, anchor slab 3 and extrusion head 5 are supporting, join together by extruder with non-bending steel cable, supporting plate 2 and whole of number cover extruding are connected into integral body by screw rod.Guiding cap 1 and supporting plate 2 foremost weld together, and non-bending steel cable 6 passes from constraint circle 8, isolating frame 7, anchor slab 3 and supporting plate 4, and its end is connected on the ground tackle 11.Between ground tackle 11 and the anchor pier 9 backing plate 10 is arranged, and firmly link with anchor pier.Grout pipe 12 penetrates from the anchor cable end, in confinement tube 8, isolating frame 7, extrusion integral, passes, and through guiding cap 1.The compound prestress anchorage cable of above-mentioned free style tension and compression is inserted from anchor hole 13, from grout pipe 12, grout in dense, and overflow from front end, be filled in the space in the anchor cable, after solidifying, promptly become tensile stress and compressive stress is tending towards even distribution, the compound prestress anchorage cable of tension and compression that anchoring effect is good by stretch-draw.Among Fig. 1, the Lo segment table shows interior free segment length, Li represents anchoring section length, supporting plate 2, anchor slab 3, bolt 4, extrusion head 5 decomposition pressure type twisted wire bundles, non-bending steel cable forms tension type twisted wire bundle by establishment, pressure-type twisted wire bundle and tension type twisted wire bundle process through establishment and are the compound prestress anchorage cable of free style tension and compression, pressure-type twisted wire bundle and tension type twisted wire Shu Gongtong constitute anchoring section, make the stack of compressive stress and tensile stress, thereby the stress distribution that has guaranteed anchoring section is even, prolong the life-span of anchor cable greatly, and obviously improved the slope anchorage effect.
Claims (1)
1, the compound prestress anchorage cable of free style tension and compression, by guiding cap, supporting plate, anchor slab, bolt, extrusion head, isolating frame, the constraint circle, grout pipe, ground tackle and non-bending steel cable constitute, it is characterized in that being positioned at the anchor slab of anchoring section front end, extrusion head and non-bending steel cable become whole through extruding, and whole of supporting plate and several extruding is chained together by screw rod, form pressure-type twisted wire bundle, with isolating frame, the tension type twisted wire bundle that constraint circle and non-bending steel cable constitute is organized in together, the anterior pressure-type twisted wire of anchoring section comes the stack with tension type streakline Shu Yingli, evenly distribute, guiding cap and supporting plate foremost are connected, ground tackle on steel strand end and the anchor pier is connected, grout pipe penetrates from the anchor cable end, through confinement tube, the through pressure-type twisted wire bundle of isolating frame and extrusion integral is the guiding cap place foremost.
