Description
Technical field
The utility model is related to a kind of moveable anchors for the old rope dismounting of bridge.
Background technology
Bridge construction technology develops rapidly in recent years in China, a variety of high performance drag-lines occurs, and such as guy of twisted steel cable is high
Strong wire digging line etc., but before the Gregorian calendar 2000, the drag-line bridge that the country of China is done also are not much hermetically sealed drag-lines, draw
Rope after installing, bridge floor and arch on built-in pipe Inner, grout injection, drag-line protected, prevent rainwater into
Enter drag-line Inner, corrodes the steel wire of drag-line, as shown in Figure 6.
Even to this day, many drag-lines are used for more than ten years, and drag-line is chronically exposed to external environment, especially drag-line
Anchor head, because anti-corrosion measure is not in place, much serious corrosions.
In recent years, a large amount of bridge needs to carry out the replacement of drag-line.Since by technology restriction at that time, the drag-line of many bridges
It is all perfused with cement mortar and carries out anti-corrosion, it is now extremely difficult to drag-line is pulled out from the built-in pipe Inner for filling cement mortar.It is more
Old drag-line is drilled out by coring bit, is operated extremely difficult using the method for drilling by number, operating expenses
It is very high.If can research and develop it is a kind of tearing the method that rope tool substitutes drilling open and dismantle these drag-lines, will to the dismounting work of the old drag-line of bridge
Make highly beneficial.
Invention content
The technical problems to be solved in the utility model is：A kind of moveable anchor for the old rope dismounting of bridge is provided, using this
Moveable anchor coordinates with jack, can extract the steel wire of drag-line from concrete, can substitute the existing side for tearing rope open using drilling
Formula has the advantages of easy to operate, to save construction cost.
Solving the technical solution of above-mentioned technical problem is：A kind of moveable anchor for bridge old rope dismounting, including anchor ring and
Intermediate plate, the anchor ring is the cylindrical structure that middle part is provided with internal taper hole, during the intermediate plate is made of three pieces arc-like sheet
Portion forms the frustum cone structure of steel tendon holding holes, and the opposite end face of adjacent two panels arc-like sheet is mutually matched inclined-plane, the folder
It is both provided with the tooth for stinging tight steel strand wires on the lateral surface and steel tendon holding holes inner wall of piece, when work, intermediate plate is located at the interior of anchor ring
In taper hole, the big end of intermediate plate and the big end of anchor ring internal taper hole are upward.
Angle β between the inclined-plane and horizontal plane of arc-like sheet is 70~80 degree.
The utility model is characterized in that：1, the endoporus of intermediate plate and outer circle have the tooth for stinging steel wire, by the cooperation with anchor ring,
Clamping steel wire；2, intermediate plate is to be divided into 3 by sawing angular cut, when clamping, ensures that entire steel wire can all be adjacent to intermediate plate,
If it is straight cut to cut, has steel wire and get into notch；3, it is applicable to the drag-line of plurality of specifications and radical, what centre clamped
As long as steel wire probably one circle of composition, extra steel wire are clamped by outer ring, steel wire is not enough covered with whole circle, can add steel wire
It is filled, ensures that steel wire is covered with entire outer ring, ensure uniform force.
The specification of wire digging line mainly has 2 kinds, 5 mm dias and 7 mm dias, can be divided again according to different radicals
Not Zu Cheng various specifications drag-line.The moveable anchor of the utility model is embedded in the steel wire inside concrete dedicated for withdrawing, and
And a kind of moveable anchor of specification, it can realize the withdrawing of plurality of specifications drag-line.Coordinated using the utility model and jack, can will be drawn
The steel wire of rope is extracted from concrete, can substitute it is existing using drilling tear rope open by the way of, have it is easy to operate, saving is constructed into
This advantages of.
In the following, in conjunction with the accompanying drawings and embodiments to a kind of technology of moveable anchor for the old rope dismounting of bridge of the utility model
Feature is further described.

Specific implementation mode
Embodiment 1：A kind of moveable anchor for the old rope dismounting of bridge, as shown in Figure 1-Figure 3, including anchor ring 1 and intermediate plate 2,
The anchor ring is the cylindrical structure that middle part is provided with internal taper hole 11, the middle part that the intermediate plate is made of three pieces arc-like sheet 21
The frustum cone structure of steel tendon holding holes 22 is formed, the opposite end face of adjacent two panels arc-like sheet is mutually matched inclined-plane, the folder
It is both provided with the tooth 23 for stinging tight steel strand wires on the lateral surface and steel tendon holding holes inner wall of piece, when work, intermediate plate 2 is located at anchor ring
In internal taper hole 11, the big end of intermediate plate and the big end of anchor ring internal taper hole are upward.
In the present embodiment, the angle β between the inclined-plane and horizontal plane of arc-like sheet is 70~80 degree, preferably 75 degree.
In the present embodiment, the end of the steel tendon holding holes 22 of intermediate plate small end is bellmouth, plays the role of transition, to keep away
Exempt from the case where intermediate plate front end stings steel wire to take an advanced study into very much steel wire fracture.
In the present embodiment, anchor ring outer end face is additionally provided with step 12, on the one hand can mitigate anchor ring weight, on the one hand also make
Anchor ring is more attractive.As a kind of transformation, step can not also be set.
Use process：The steel wire of drag-line is collapsed into circular steel tendon, outer diameter and folder after the selection of intermediate steel wire is collapsed
The steel tendon holding holes of piece are almost big or somewhat larger, and remaining steel wire is isolated in the periphery of intermediate plate by intermediate plate, by intermediate plate
It is matched for clamping tightly with anchor ring, when steel wire is not enough covered with the whole circle in intermediate plate periphery, steel wire can be added and be filled, ensure that steel wire is covered with entirely
Outer ring ensures uniform force.Last urgent intermediate plate, starts jack, so that it may to pull out steel wire from concrete（Such as Fig. 4-
Shown in Fig. 5）.
