Abstract
A supporting lug with top pressing and top loosing clip functions and clip limit is used for drawing an anchorage device for a steel strand wire and is characterized in that a clip top pressing plate and a clip top loosing plate B are arranged in a limit supporting lug; the clip top pressing plate is connected with the limit supporting lug through a position adjusting mechanism; and the clip top loosing plate B is connected with the limit supporting lug by a position adjusting mechanism B. The supporting lug has the advantages that: the stress loss of an inhaul cable is reduced to the most extent, so that a limit device, a force-bearing supporting lug, a tool anchor, a tool clip and a jack are not needed to be switched in the process that the inhaul cable is used for mounting drawing equipment at a time, and furthermore, the integral length of the equipment is shortened, the automatic anchor return is realized, the steel strand wire can be clamped and drawn repeatedly, and the steel strand wire without limit in length can be drawn to reach the preset control stress at a time.
Description
Technical field
The utility model relates to a kind of band roof pressure and loose intermediate plate function in top and the spacing spike of intermediate plate that steel strand anchorage is carried out stretch-draw.
Background technology
At present steel strand are carried out the suspension cable of stretch-draw and the suspension stretch-draw majority of steel strand external tendon ground tackle is arranged in anchoring drag-line in the small space; The drag-line tentioning stroke needs tensioning equipment repeatedly to return back to top all greater than 200mm, and present used tensioning equipment; Entire length is long; To repeatedly carry out the roof pressure and top pine of work clip sheet at work, also need change stopping means, thereby the drag-line stress loss be bigger.
The utility model content
It is stressed in multiple conversions that the purpose of the utility model just provides a kind of two cover instrument ground tackles that utilize; All the time roof pressure is right after the work clip sheet clamping of cable anchorage in the time of keeping stretch-draw to the design stress value; And can stretch-draw to design during stress value roof pressure strain at the work clip sheet of cable anchorage; Make it reduce the loss of drag-line stress to greatest extent; Thereby realize need not changing stopping means, stressed spike, moveable anchor, instrument intermediate plate, jack midway behind the drag-line once mounting tensioning equipment, and the band roof pressure in the length space that takies the dragline anchorage axis direction that can be minimum and loose intermediate plate function in top and the spacing spike of intermediate plate.
The solution of the utility model is such: in spacing spike, be provided with intermediate plate top pressing board and intermediate plate and push up loose B plate; Described intermediate plate top deals is connected with spacing spike through position adjusting mechanism, and described intermediate plate pushes up loose B plate and is connected with spacing spike through position adjusting mechanism B.
The utility model has the advantages that the loss that reduces drag-line stress to greatest extent; Thereby realize need not changing stopping means, stressed spike, moveable anchor, instrument intermediate plate, jack midway behind the drag-line once mounting tensioning equipment; Shortening equipment entire length; Can realize returning automatically grip and hold steel strand stretch-draw repeatedly, but the single tension of the unrestricted steel strand length of stretch-draw is to the proof stress of setting.
Description of drawings
Accompanying drawing is the embodiment of the utility model.
Accompanying drawing 1 is the structural representation of the utility model.
The specific embodiment
In the present embodiment, each parts is detailed as follows:
1, work anchor slab, 2, work clip sheet, 3, intermediate plate top pine cover, 4, spacing spike garter spring, 5, the intermediate plate top pressing board; 6, split washer, 7, spacing spike, 8, soket head cap screw, 9, instrument anchor slab A, 10, soket head cap screw; 11, jack, 12, instrument anchor slab pressure ring, 13, soket head cap screw, 14, instrument anchor slab B; 15, locking plate, 16, soket head cap screw, 17, the instrument intermediate plate, 18, retracting spring; 19, steel strand, 20, soket head cap screw, 21, intermediate plate top deals B, 22, soket head cap screw.
The utility model is provided with intermediate plate top pressing board 5 and pushes up loose B plate 21 with intermediate plate in spacing spike 7, described intermediate plate top pressing board 5 is connected with spacing spike 7 through position adjusting mechanism, and described intermediate plate pushes up loose B plate 21 and is connected with spacing spike 7 through position adjusting mechanism B.
Described position adjusting mechanism comprises the intermediate plate top pressing board 5 that has two screwed holes at least, the bolt 8 that is connected spacing spike 7; Pass intermediate plate and push up the through hole on the loose B plate 21; Threaded portion is connected with intermediate plate top pressing board 5; It can be reached and when stretch-draw, unclamp work clip sheet, and make not clamping of work clip sheet steel strand through the distance of bolt 8 adjusting intermediate plate top pressing boards 5; When repeatedly the stretch-draw of leading journey puts in place, can not get when taking off and make intermediate plate top pressing board 5 hold out against the stressed anchoring of work clip sheet once adorning jack through regulating bolt 8.
Described position adjusting mechanism B comprises that the intermediate plate that has two screwed holes at least pushes up loose B plate 21, is connected the B crab bolt 22 of spacing spike 7, and the threaded portion of B crab bolt 22 pushes up loose B plate 21 with intermediate plate and is connected.
One end of said spacing spike 7 is connected with instrument anchor slab 9, and the other end of instrument anchor slab 9 contacts the jack 11 and instrument anchor slab B14 of band pressure when stretch-draw successively.
The one end connection of described spacing spike 7 is pressed on the work anchor slab 1, and the end that spacing spike 7 mills out is equipped with spacing spike garter spring 4, makes it can prevent that spike is radially risen greatly when stretch-draw is stressed, and makes spacing heel brace 7 ring-type stress surfaces skid off work clip sheet 2.
Right-hand member at described instrument anchor slab 9 is connected with locking plate 15a, described locking plate 15a cover Cui steel strand 19, and its end face is connected with the spring that withstands work clip sheet one end.
Right-hand member at described instrument anchor slab B14 is connected with locking plate 15, described locking plate 15 cover Cui steel strand 19, and its end face is connected with the spring that withstands work clip sheet one end.
The course of work of the utility model is:
1, roof pressure intermediate plate: regulate bolt 8, intermediate plate top pressing board 5 is promoted left, roof pressure work clip sheet 2,
2, push up loose intermediate plate: regulate bolt 22, intermediate plate is pushed up loose B plate 21 promote, roof pressure intermediate plate top pine cover 3, the function of the loose intermediate plate in realization top to the right.
3, intermediate plate is spacing: regulate bolt 8, and the position of the left end of scalable intermediate plate top pressing board 5 and work clip sheet 2 terminations, thus carry out spacing to the termination of work clip sheet 2.
When piston stretch-draw was stretched out, instrument anchor slab B14 clamping steel strand bore pressure and eject, and instrument anchor slab A9 intermediate plate unclamps automatically, and anchor slab is false.
When piston reclaimed, the retracting spring 18a at instrument anchor slab A9 place held out against intermediate plate automatically, and instrument anchor slab A9 sets up, and instrument anchor slab B14 unclamps automatically, is recovered to the zero elongation position simultaneously with piston, the proof stress that the automatic reciprocating circulation of above-mentioned action is arrived until stretch-draw.
