Abstract
A kind of monolithic Anti-loose cable force adjustment device, comprise anchoring part, the stretch-draw spike be packed on anchoring part, the steel strand running through stretch-draw spike, the work anchor be sleeved on steel strand, moveable anchor A and jack, it is characterized in that: locking pressing plate is housed on work anchor, at the afterbody of stretch-draw spike, moveable anchor B be housed and be sleeved on steel strand.The utility model is in button, anchor cable (or suspension cable, suspension cable) cable force adjustment process, cable tension or reduction can be realized by jack, by the alternation of moveable anchor A, moveable anchor B, the integrated regulation with group cable force can be realized, and effectively can prevent loosening of rope in cable force adjustment process.The workload that the utility model convenient and quick construction, safety and control accuracy be high, greatly reduce cable force adjustment, has saved construction period and cost.
Description
Technical field
The utility model belongs to a kind of bridge construction equipment, in particular to a kind of monolithic Anti-loose cable force adjustment device, this device belongs to button, anchor cable cable force adjustment device, is highly suitable for various cable force adjustment in the bridge type work progresss such as arch bridge stiff skeleton segment lifting, cable stayed bridge, suspension bridge.
Background technology
In conjunction with the Construction practices of current arch bridge, cable stayed bridge and suspension bridge both at home and abroad, when detaining anchor cable, suspension cable or suspension cable cable force adjustment, the single jack of many employings or ordinary unit jack carry out cable force adjustment.When adopting single top mode to carry out by root lock cable force adjustment, because Suo Li exists successively adjustment order, very easily cause the Suo Li between same group of different rope unbalanced, as excessive in indivedual Suo Li, be very easy to cause rope to rupture and cause security incident.Ordinary unit cable loosing device, due to the repeatedly use of anchor clipper in cable loosing process, Suo Jiyi occurs to loosen and causes security incident.
Summary of the invention:
The purpose of this utility model is just to overcome above-mentioned the deficiencies in the prior art, and a kind of monolithic Anti-loose cable force adjustment device is provided, this device is by carrying out simple reformation to ordinary unit cable force adjustment device, even stretch-draw can be carried out to Suo Li, especially both can carry out accurately multi beam button, anchor cable force in cable force adjustment process simultaneously, evenly, rapid adjustment, can effectively avoid again the unbalanced and button anchor cable of each bundle cable force in cable force adjustment process to loosen the security incident of initiation.
As above conceive, the technical solution of the utility model is: a kind of monolithic Anti-loose cable force adjustment device, comprise anchoring part, the stretch-draw spike be packed on anchoring part, the steel strand running through stretch-draw spike, the work anchor be sleeved on steel strand, moveable anchor A and jack, it is characterized in that: locking pressing plate is housed on work anchor, at the afterbody of stretch-draw spike, moveable anchor B be housed and be sleeved on steel strand.
Above-mentioned locking pressing plate is arranged on work anchor by bolt.
The utility model is in button, anchor cable (or suspension cable, suspension cable) cable force adjustment process, cable tension or reduction can be realized by jack, by the alternation of moveable anchor A, moveable anchor B, the integrated regulation with group cable force can be realized, and effectively can prevent loosening of rope in cable force adjustment process.The workload that the utility model convenient and quick construction, safety and control accuracy be high, greatly reduce cable force adjustment, has saved construction period and cost.
Accompanying drawing illustrates:
Fig. 1 is structure chart of the present utility model;
Fig. 2 is the structure chart of work anchor.
1. anchoring parts, 2. work anchor in figure, 3. locking pressing plate, 4. stretch-draw spike, 5. jack, 6. moveable anchor A, 7. steel strand, 8. moveable anchor B, 9. bolt.
Detailed description of the invention:
As shown in Figure 1, 2: a kind of monolithic Anti-loose cable force adjustment device, comprise anchoring part, the stretch-draw spike be packed on anchoring part, the steel strand running through stretch-draw spike, the work anchor be sleeved on steel strand, moveable anchor A and jack.Work anchor is equipped with locking pressing plate by bolt, at the afterbody of stretch-draw spike, moveable anchor B is housed and is sleeved on steel strand.
In the utility model, moveable anchor A directly bears Suo Li in cable force adjustment process, by intermediate plate by rope firm grip, avoids occurring to loosen causing security incident.
The utility model is in cable force adjustment process, intermediate plate clamps when jack backhaul about remaining 20mm by moveable anchor B, then jack continues backhaul, Suo Li is all transferred to moveable anchor B, be convenient to moveable anchor A and jack and carry out next adjustment circulation, ensure that in jack circulation adjustment process, rope does not loosen.
Realized the adjustment of Suo Li by the stretch-draw of jack and backhaul in the utility model.
After the locking pressing plate of ground tackle of the present utility model can avoid cable force adjustment to complete, rope loosens.
The course of work of the present utility model is:
One, Suo Li mends method for stretching:
The first step: the locking pressing plate 3 first removing work anchor 2, by jack 5 backhaul, clamping tool anchor A, moveable anchor B keep unclamping; Second step: make jack 5, dials loose ground tackle 2 intermediate plate simultaneously; After about 3/4 stroke got by jack, moveable anchor B intermediate plate clamps;
3rd step: jack 5 backhaul, clamping tool anchor A, makes jack 5, pushes up loose moveable anchor B.
4th step: carry out next step dozen of jack 5, after about 3/4 stroke got by jack, moveable anchor B intermediate plate clamps.
5th step: repeat above-mentioned steps, when steel strand 7 pulling force benefit opens one's eyes wide scale value, retaining tool anchor B opens, moveable anchor A clamped condition.
6th step: clamped by work anchor clipper, jack 5 backhaul, removes tensioning equipment, compresses the locking pressing plate 3 of work anchor 2, fixes follower bolt 9.
Two, Suo Li minishing method:
The first step: the locking pressing plate 3 first removing work anchor 2, about 3/4 stroke got by jack 5, and moveable anchor A clamps, and moveable anchor B opens.
Second step: continue to make jack 5, pull out loose work anchor 2, take off intermediate plate after unclamping, retaining tool anchor A clamps, and moveable anchor B opens, jack 5 backhaul, during to backhaul about remaining 20mm, moveable anchor B clamps.
3rd step: jack 5 continues backhaul, power is transformed into moveable anchor B, and moveable anchor A unclamps, and retaining tool anchor A unclamps.
4th step: about 3/4 stroke got by jack 5, moveable anchor A clamps, and continues to make jack 5, pushes up loose moveable anchor B.
5th step: next step jack backhaul, during to backhaul about remaining 20mm, moveable anchor B clamps, and jack 5 continues backhaul, and power is transformed into moveable anchor B, and moveable anchor A unclamps, and moveable anchor B clamps.
6th step: repeat above-mentioned steps, when steel strand 7 pulling force benefit opens one's eyes wide scale value, retaining tool anchor B opens, moveable anchor A clamped condition.
7th step: clamped by work anchor 2 intermediate plate, jack continues backhaul, removes tensioning equipment, compresses the locking pressing plate 3 of ground tackle 2, fixes follower bolt 9.
Requirement can only be put into close to 3/4 stroke, and moveable anchor A and moveable anchor B wants its initial clamped condition of Artificial Control.
