Abstract
The invention relates to a supporting pad for loosening and fastening a pre-stressed anchor cable, which comprises a supporting pad body, an anchor pier plate, an anchor plate, an anchor cable and a top plate, and is characterized in that the supporting pad (1) is made into a hollow convex shape, the width of a lower gap of the convex shape is slightly greater than the width of the anchor plate (4), the height of the gap is equal to the height of the anchor plate (4), the width of the upper part of the convex shape is greater than the width of a spring clamping piece (2) on the anchor plate (4), and the supporting pad body (1) is inserted into the space between the top plate (6) and the anchor pier plate (3) so as to loosen the anchor cable (5). Compared with the prior art, the supporting pad provided by the invention has the advantages of simple structure, convenience in operation, good using effect and the like.
Description
Technical field
The invention belongs to pre-stress construction field, especially a kind of cradle of the fastening prestress anchorage cable that gets loose.
Background technology
In construction prestressed cable process, when utilizing hydraulic jack stretch-draw anchor to reach the stress intensity value of design, be locked on anchor upsetting plate with anchor plate and spring clip.There is stretch-draw angle, ground tackle slides, support backing plate modification, the factors such as stretching force is unreasonable, or carry out second time stretch-draw stress application by technological requirement, the anchor cable that needing gets loose again produces prestressing force tensioning is a more difficult job, often adopts the method damaging ground tackle or cutting removing lip block to solve, waste resource and effort of taking a lot of work in work.
Summary of the invention
The object of the invention is to overcome above-mentioned Problems existing, the cradle of the fastening prestress anchorage cable that gets loose that a kind of structure is simple, easy to operate, result of use is good is provided.
As follows for reaching the technical solution that above-mentioned object takes:
1, a kind of cradle of the fastening prestress anchorage cable that gets loose, comprise cradle, anchor pier plate, anchor plate, anchor cable, top board, it is characterized in that described cradle makes interior empty convex shape, the width of convex shape lower space is slightly larger than the width of anchor plate, the height in space is equal to the height of anchor plate, the width on convex shape top is greater than the spring clip width on anchor plate, and get loose after between cradle insertion top board and anchor upsetting plate anchor cable.
The cradle of a kind of fastening prestress anchorage cable that gets loose 2, as described in technical scheme 1, wherein, described anchor plate is provided with multiple bellmouth, penetrate anchor cable and place spring clip, use hydraulic jack stretch-draw anchor, make anchor cable produce certain prestressing force, spring clip is pressed in the bellmouth of anchor plate by the hydraulic jack other end simultaneously, and anchor cable is locked on anchor pier plate tightly.
The present invention compared with prior art, has structure simple, easy to operate, the advantages such as result of use is good.
accompanying drawing illustrates:
Fig. 1 is overall structure stereogram of the present invention,
Fig. 2 is embodiments of the invention front view,
Fig. 3 is A-A sectional view in Fig. 2 of the present invention.
In fig. 1-3, cradle (1), spring clip (2), anchor pier plate (3), anchor plate (4), anchor cable (5), top board (6).
detailed description of the invention:
below in conjunction with drawings and Examples, the present invention is further described:
Shown in Fig. 3, a kind of cradle of the fastening prestress anchorage cable that gets loose, comprise cradle, anchor pier plate, anchor plate, anchor cable, top board, wherein, described cradle 1 makes interior empty convex shape, and the width of convex shape lower space is slightly larger than the width of anchor plate 4, and the height in space is equal to the height of anchor plate 4, the width on convex shape top is greater than spring clip 2 width on anchor plate 4, and cradle 1 inserts the anchor cable 5 that to get loose after between top board 6 and anchor upsetting plate 3.
Described anchor plate 4 is provided with multiple bellmouth, penetrate anchor cable 5 and place spring clip 2, with hydraulic jack stretch-draw anchor 5, anchor cable 5 is made to produce certain prestressing force, spring clip 2 is pressed in the bellmouth of anchor plate 4 by the hydraulic jack other end simultaneously, and anchor cable 5 is locked on anchor pier plate 3 tightly.
In normal construction process, described anchor plate 4 is provided with multiple bellmouth, penetrate anchor cable 5 and place spring clip 2, utilize hydraulic jack stretch-draw anchor 5, anchor cable 5 is made to produce certain prestressing force, spring clip 2 is pressed in the bellmouth of anchor plate 4 by the hydraulic jack other end simultaneously, and anchor cable 5 is locked on anchor pier plate 3 tightly.
If anchor cable 5 again will be got loose, a cradle 1 is put between top board 6 and anchor upsetting plate 3, and ride on anchor plate 4, press on the top plate 6 with hydraulic jack one end again, distance certain for anchor cable 5 stretching extension makes spring clip 2 shrink back and loosens by jack other end tension clamp, anchor cable 5 produces gap with the bellmouth on anchor plate 4, and after removing spring clip 2, retraction hydraulic jack makes anchor cable 5 recover relaxed state.
Concrete operations: cradle 5 is put into from the side and rides on anchor plate 4, anchor cable 5 penetrates in hydraulic jack, jack one end is pressed on the top plate 6, described top board 6 is pressed on cradle 5, directly be not pressed onto spring clip, the anchor cable 5 of the jack other end is fixed with tension clamp, crawl hydraulic jack, stretch-draw anchor 5 extends the spring clip 2 that certain distance makes it be locked at anchor plate 4 and shrinks back loosening, make to occur gap between the bellmouth on anchor cable 5 and anchor plate 4 and spring clip 2, removing spring clip 2 is provoked with screwdriver, loosen retraction hydraulic jack again, and reach anchor cable 5 and be separated with anchor plate 4 and recover original relaxed state.If carry out two times tensioning anchor cable 5 by technological requirement, as long as cradle 1 is removed, spring clip 2 is filled between the bellmouth and anchor cable 5 of anchor plate 4, hydraulic jack one end is pressed on spring clip 2, the other end installs tension clamp additional can carry out two times tensioning, and stretch-draw anchor 5 produces prestressing force and is locked on anchor upsetting plate 3 by anchor plate 4 and spring clip 2.
