Abstract
The utility model discloses a prestressing force loading device for a glass fiber rib anchor rod. The prestressing force loading device is characterized in that a steel sleeve is sleeved in the anchoring hole of the anchoring table of a side slope glass fiber rib anchor rod, and the inner wall of the steel sleeve and the side slope glass fiber rib anchor rod are bonded through epoxy resin; the upper end of the steel sleeve is in threaded connection with the lower end of a lower connection rod, and the upper end of the connection rod is in threaded connection with the lower end of an upper connection rod by penetrating through a lower bearing plate embedded on the upper surface of the anchoring table; the lower connection rod is in threaded connection with a locking nut at a part above the lower bearing plate; the upper end of the upper connection rod is connected with a fixing nut after penetrating through an upper bearing plate and a hollow hydraulic jack; the upper bearing plate is fixed on the lower bearing plate through four counter-force rods in a threaded manner. When the prestressing force loading device disclosed by the utility model applies prestressing force, no shearing destruction on the anchor rod generates, and precise prestressing force can be effectively provided for the side slope glass fiber rib anchor rod; the prestressing force loading device is easy to disassemble, can be repeatedly used, and is conveniently applied to traffic-inconvenient mountain area side slopes.
Description
Technical field
The utility model belongs to technical field of civil engineering, particularly the prestressing force loading technique field of side slope glass fiber muscle anchor pole.
Background technology
Side slope prestress anchoraging is a kind of measure that increases slope stability with anchoring process.Its method be beat, boring through likely slide or the slide plane that slided, one end of reinforcing bar (or cable wire) is fixed in the stable Rock And Soil at the bottom of hole, again reinforcing bar (or cable wire) is strained so that can be produced certain prestressing force, then the other end side slope of reinforcing bar (rope) is fixed on to side slope surface, utilizing the prestressing force of reinforcing bar to compress can slidable slope ground body or retaining structure, to increase the shear strength on slide plane, thereby reach the object that improves slope stability.
Glass fiber muscle is a kind of take resin as matrix material, and alkali-free glass fibre is main reinforcing material, and that makes by pultrusion molding process has a corrosion resistant new material of high-strength light.Glass fiber muscle anchor pole is very fast as a kind of novel slope retaining anchor pole development, in mine, slope retaining, obtains certain application abroad.Equal conditions lower-glass fiber anchor rod is applied to side slope permanent support and compares reinforced anchor bolt and have better tension, stronger durability.But due to the horizontal shear resistance of fiber bar than the horizontal shear resistance of plain bars anchor pole very a little less than, as adopt existing reinforced anchor bolt prestressing force charger, the transverse shearing force that its fixture produces can make glass fiber muscle anchor pole that horizontal shear failure occurs, cause glass fiber muscle anchor rod prestress cannot load or load and do not reach design load, make its anchoring support weak effect.
Utility model content
The purpose of this utility model is just to provide a kind of prestressing force loading equipemtn for side slope glass fiber muscle anchor pole, and this equipment can not produce shear failure to anchor pole in the time applying prestressing force, can effectively provide accurate prestressing force to side slope glass fiber muscle anchor pole; And be easy to dismounting, energy Reusability, be conducive to use in ungetable mountain area side slope.
The utility model for the technical scheme that realizes its goal of the invention and adopt be that a kind of prestressing force loading equipemtn for glass fiber muscle anchor pole, is characterized in that:
In the anchoring platform anchor hole of side slope glass fiber muscle anchor pole, be sheathed with steel sleeve, the inwall of steel sleeve and side slope glass fiber muscle anchor pole pass through epoxy bond;
The upper end of steel sleeve is threaded with the lower end of lower connecting rod, and the upper end of lower connecting rod is threaded with the lower end of upper connecting rod after passing the lower loaded plate that is embedded in anchoring platform upper surface; Lower connecting rod position above lower loaded plate locking nut that has been threaded;
The upper end of upper connecting rod is passed upper loaded plate and is connected with hold-down nut with after hollow hydraulic jack;
Upper loaded plate is fixed on lower loaded plate by four counter-force bar screw threads.
The course of work of the present utility model and principle are:
Fit steel sleeve in the anchoring platform anchor hole of side slope glass fiber muscle anchor pole, the inwall of steel sleeve and side slope glass fiber muscle anchor pole pass through epoxy bond.
The degree of depth that is threaded that regulates four counter-force bar screw threads and lower loaded plate, makes loaded plate vertical with upper and lower connecting rod and side slope glass fiber muscle anchor pole.Adjusting lock nut makes it upwards depart from lower loaded plate, then tightens hold-down nut.
Subsequently, open hollow hydraulic jacking oil pump, by hollow hydraulic jack, upper connecting rod, lower connecting rod, steel sleeve 2 stretch-draw glass fiber muscle anchor poles, in the time that stretching force reaches design load, tighten locking nut, the prestressing force of anchor pole loads anchor pole and completes and be fixed.
After loading completes, to jack pressure release, remove successively jack, upper connecting rod, upper loaded plate and counter-force bar; The parts that remove can supply Reusability.
Compared with prior art, the beneficial effects of the utility model are:
One, transmit axial prestress by the steel sleeve of inwall and glass fiber muscle anchor pole epoxy bond to anchor pole, than passing through fixture clamping glass fiber anchor rod, anchor pole shearing force reduces greatly, almost nil; Regulate and can guarantee that loaded plate is vertical with glass fiber anchor pole by four counter-force bars and the depth of thread thereof simultaneously, thereby assurance does not produce transverse shearing force while applying prestressing force, can not produce shear failure to anchor pole, solve the problem that jack can not direct drawing glass fiber anchor pole.
Two, steel sleeve and glass fiber anchor pole are bonding solid and reliable, in avoiding that anchor pole is produced to cross shear, have also avoided the slippage between glass fiber anchor pole and steel sleeve, and prestressing force loads accurately.
Three, between steel sleeve and anchor pole, be that bonding, remaining part is and is threaded, easy for installation being easy to of equipment dismantled; The parts such as upper connecting rod, upper loaded plate, counter-force bar all can Reusability; Be conducive to use in ungetable mountain area side slope.
Below in conjunction with accompanying drawing and concrete embodiment, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of the utility model embodiment equipment.
