Abstract
The utility model relates to a cross-ear type steel-strand stay cable anchor which comprises a squeezing anchor cup connected with a cross ear, a squeezing anchor plate with a through hole, a sealing and anchoring cylinder, a telescopic cylinder and a steel-strand stay cable. The squeezing anchor plate is mounted in the squeezing anchor cup; a steel strand is sleeved with a squeezing sleeve after passing through the through hole of the squeezing anchor plate; a squeezing sleeve pressing board is arranged at the end part of the squeezing sleeve; the sealing and anchoring cylinder is sleeved outside the steel-strand stay cable and is connected with the squeezing anchor cup; the telescopic cylinder is sleeved outside the steel-strand stay cable and is connected with the sealing and anchoring cylinder; a sealing cushion plate, a sealing cushion and a turning device are sequentially arranged on the steel-strand stay cable inside an end part of the telescopic cylinder, which is connected with the sealing and anchoring cylinder, along a direction from the sealing and anchoring cylinder to the telescopic cylinder; and an anti-corrosion material is filled inside the squeezing anchor cup and between the sealing and anchoring cylinder and the steel-strand stay cable. The cross-ear type steel-strand stay cable anchor provided by the utility model has the attractive appearance, is particularly suitable for a bridge in a steel structure, and has the greatest advantage of being rapid in mounting and construction speed. Compared with an ordinary stay cable, which is mounted by hanging and tensioning single strands, the cross-ear type steel-strand stay cable anchor can be mounted in position for one time.
Description
Technical field
The utility model relates to a kind of ground tackle, particularly a kind of fork ear formula guy of twisted steel cable ground tackle.
Background technology
250 drag-lines are in bridge construction; Number of applications in the construction of cable stayed bridge particularly, 250 drag-lines can single extension cable stretchings when construction, are specially adapted to long suspension cable; Because whole whole relatively difficulty of cable stretching of hanging of drag-line; And the construction equipment that needs is also many, so increasing 250 drag-lines are applied in the construction of cable stayed bridge 250 dragline anchorages of most domestic; Basically all be that two ends are strand tapered anchorage (referring to Fig. 3), bridge tower end and girder end all need anchor plate and pre-buried pipe like this.The bridge of this type is more suitable for the bridge of reinforced concrete structure; This type bridge outward appearance is not very attractive in appearance, and along with the increase of domestic national power, each city is paid attention to the aesthetic property of bridge more; A large amount of in recent years bridges that emerges steel work; This type bridge construction speed is fast, and structure is attractive in appearance, and the ground tackle that most of bridge tower end is provided with is fork ear formula ground tackle; The fork ear formula ground tackle of existing structure only is applied on monolithic extruded formula guy of twisted steel cable and the high tensile steel wire suspension cable at present, and the drag-line of this structure is more difficult at all relative 250 drag-lines with installation of system rope for the big suspension cable of length.But because 250 stayed structures, its ground tackle is a strand tapered anchorage, can't make fork ear formula structure.
Summary of the invention
The technical problem that the utility model will solve is: a kind of handsome in appearance, bridge of being particularly suitable for steel work is provided, and the fork ear formula guy of twisted steel cable ground tackle of the fast and good seal performance of installation speed has solved the problem that exists in the above-mentioned prior art.
The technical scheme that solves the problems of the technologies described above is: a kind of fork ear formula guy of twisted steel cable ground tackle, comprise extruding anchor cup, extruding anchor slab, sealing anchorage drum, retracting cylinder and guy of twisted steel cable, and be connected with the fork ear on the described extruding anchor cup; Described guy of twisted steel cable is to be made up of N root steel strand; Have N through hole on the described extruding anchor slab, the extruding anchor slab is installed in the extruding anchor cup, and steel strand are set with extruded sleeve after passing the through hole that pushes anchor slab; The extruded sleeve end is equipped with the extruded sleeve pressing plate; Be filled with anti-corrosion material in the extruding anchor cup, the sealing anchorage drum is sleeved on outside the guy of twisted steel cable and with extruding anchor cup and is connected, and retracting cylinder is sleeved on outside the guy of twisted steel cable and with the sealing anchorage drum and is connected; Being positioned at retracting cylinder is connected on the guy of twisted steel cable of end with the sealing anchorage drum; Be disposed with sealed bolster plate, sealing mat and turner from the sealing anchorage drum toward the retracting cylinder direction, be filled with anti-corrosion material between described sealing anchorage drum and the guy of twisted steel cable, the value of N is 2-50.
The steel strand of described composition guy of twisted steel cable are that epoxy is filled steel strand, and described guy of twisted steel cable also is provided with the HDPE outer tube outward, and HDPE outer tube one end cover is packed in the retracting cylinder.
Described anti-corrosion material is an epoxy mortar.
Described sealing anchorage drum end is connected with the turner pressure ring that is used to compress turner.
Because adopt said structure, the fork ear formula guy of twisted steel cable ground tackle of the utility model has following beneficial effect:
1. handsome in appearance, be particularly suitable for the bridge of steel work.
2. biggest advantage is that installation speed is fast, whole drag-line can be on bridge floor overall package good, directly winch to the bridge tower position with crane again, put on bearing pin and promptly accomplish the extension rope, once mounting puts in place, need not resemble single extension rope and stretch-draw common 250 drag-lines.
3. good seal performance after perfusion epoxy mortar in the extruding anchor cup, has been stopped extraneous corrosion basically.
Below, in conjunction with accompanying drawing and embodiment the technical characterictic of the fork ear formula guy of twisted steel cable ground tackle of the utility model is further described.
