Abstract
The utility model relates to a clamping piece anti-loosing apparatus for a steel strand group anchoring device inhaul cable ground tackle, which is composed of a pressing plate, and hollow screws which are arranged on the rear end of each clipping sheet of each anchoring unit. The pressing plate is fixed on an anchoring plate through screws, and the hollow screws pass through holes on the pressing plate to be tightly butted on the rear end of clipping sheets. Each clipping sheet of each anchoring unit bears an acting force which tight presses towards a hole of the anchoring plate, to ensure the anchoring safety of each anchoring unit, and the singly adjustable tight press force of the clipping sheet of each anchoring unit and the displacement of the clipping sheet of each anchoring unit can be realized. The utility model can effectively prevent the phenomenon of clipping sheet loosening from generating in various causes, thereby, the anchoring is safety under work conditions of the low stress value and dynamic load in high stress width, and the effective tailgate of the clipping sheet is kept.
Description
The utility model belongs to a kind of intermediate plate locking device of steel hinge line group anchor cable ground tackle.
The existing low stress values (0.45 that is used for
σ b), the intermediate plate of the steel hinge line group anchor cable ground tackle of heavily stressed width of cloth dynamic load effect comes the tight presstressed reinforcing steel of clamping because of only depending on intermediate plate and steel hinge line contact plane frictional resistance, be effectively to prevent the intermediate plate clamping presstressed reinforcing steel that causes by a variety of causes generation of phenomenon that gets loose, thereby cause prestressed failure.
The purpose of this utility model is to provide a kind of intermediate plate locking device of the steel hinge line group anchor cable ground tackle that phenomenon produces that can effectively prevent intermediate plate clamping presstressed reinforcing steel to get loose.
Intermediate plate locking device provided by the utility model is made up of pressing plate and the hollow bolt that is contained in each intermediate plate rear end, anchoring unit, and on anchor slab, the through hole that hollow bolt passes pressing plate holds out against the rear end at intermediate plate to pressing plate by bolton.
Because the utility model holds out against intermediate plate rear end in each anchoring unit with hollow bolt, therefore make the intermediate plate of each anchoring unit all can be subjected to an active force that compresses to the anchor slab hole, realize that simultaneously each suffered thrust of anchoring unit intermediate plate and displacement are adjustable separately, 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 dynamic load operating mode, make anchoring more reliable, and effective follow-up of keeping clip.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1---be structural representation of the present utility model.
As shown in Figure 1, locking device provided by the utility model is made up of pressing plate 1 and the hollow bolt 4 that is contained in each intermediate plate 5 rear end, anchoring unit, pressing plate 1 is fastened on the anchor slab 6 by bolt 2, stop collar 3 is enclosed within passes on pressing plate 1 bolt 2, be used to limit the distance between pressing plate 1 and the anchor slab 6, on pressing plate 1 and intermediate plate 5 corresponding positions, have through hole, hollow bolt 4 passes through hole on the pressing plate 1 and holds out against rear end at intermediate plate 5, the intermediate plate of each anchoring unit all can be subjected to an active force that compresses to the anchor slab hole, make intermediate plate 5 can't withdraw from the anchor slab hole at the force direction that is subjected to of presstressed reinforcing steel 7, the presstressed reinforcing steel 7 that assurance is passed behind anchoring unit intermediate plate 5 and the hollow bolt 2 is tightly clamped by intermediate plate 5.
