Abstract
The utility model discloses a clamping piece anti-loosing apparatus for steel strand group anchor ground tackle, which is composed of pressing plates and disk spring shims fixed at the back end of the clamping piece of each anchor unit, wherein, the pressing plates are tightly fixed on anchor plates by bolts. By using the self elastic force, the disk spring shims which are arranged between the pressing plates and the back ends of the clamping pieces tightly push the clamping pieces to enable each clamping piece to get the acting force for tightly pressing in the holes of the anchor plates. The clamping pieces can not back out from the holes of the anchor plates in the force stress direction of tendon to assure that the anchor of each anchor unit becomes completely reliable. The loose phenomenon of the clamping pieces caused by a variety of causes is effectively prevented, and the effective tailgate of the clamping pieces is maintained.
Description
The intermediate plate that the utility model relates to a kind of steel hinge line group anchor ground tackle loosens and takes off device.
Existing steel hinge line group anchor ground tackle is in stress value (0.65
σ b), under the low stress width of cloth (less than 80Mpa), be that the frictional resistance by anchor clipper and presstressed reinforcing steel contact plane clamps presstressed reinforcing steel, but in low stress values (0.45
σ bBelow), to only depend on the frictional resistance of intermediate plate and presstressed reinforcing steel under the heavily stressed width of cloth dynamic load operating mode be effectively to prevent the intermediate plate clamping presstressed reinforcing steel that is caused by a variety of causes generation of phenomenon that gets loose, thereby cause prestressed failure.
The purpose of this utility model provides a kind of under low stress values, heavily stressed width of cloth dynamic load operating mode, the intermediate plate anti-loosing device of the steel hinge line group anchor ground tackle that phenomenon takes place that can effectively prevent intermediate plate clamping presstressed reinforcing steel to get loose.
Intermediate plate provided by the utility model loosens and takes off device and be made up of pressing plate and the dish formula spring shim that is contained in each intermediate plate rear end, anchoring unit, on anchor slab, the dish formula spring shim that is contained between pressing plate and the intermediate plate rear end utilizes the elastic force of self to hold out against intermediate plate to pressing plate by bolton.
Because of the utility model is to utilize the elastic force of the dish formula spring shim that is contained in the intermediate plate rear end to hold out against intermediate plate, make the intermediate plate of each anchoring unit all can be subjected to an active force that in the anchor slab hole, compresses, the anchoring that guarantees each anchoring unit is safe and reliable, can effectively prevent by the get loose generation of phenomenon of the intermediate plate that a variety of causes causes, thereby under low stress values, heavily stressed width of cloth operating mode dynamic load, make anchoring more safe and reliable, and effective follow-up of keeping clip.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1---be structural representation of the present utility model.
Referring to Fig. 1, this intermediate plate loosens and takes off device by being made up of pressing plate 2 and the dish formula spring shim 3 that is contained in each intermediate plate 4 rear end, anchoring unit, after each anchoring unit intermediate plate 4 is locked presstressed reinforcing steel 5 admittedly, dish formula spring shim 3 is placed on intermediate plate 4 rear ends refills top board 2, pressing plate 2 is fastened on the anchor slab 6 by bolt 1 and compresses dish formula spring shim 3, the elastic force that dish formula spring shim 3 distortion backs produce holds out against intermediate plate 4, each intermediate plate 4 all is subjected to an active force that compresses in the anchor slab hole, make intermediate plate can't withdraw from the anchor slab hole, and pass anchoring unit intermediate plate 4 at the force direction that is subjected to of presstressed reinforcing steel, the presstressed reinforcing steel 5 of dish formula spring shim 3 and pressing plate 2 is tightly clamped by intermediate plate 4.
