Abstract
The utility model relates to a double-anchoring anchor rod. A spiral anchoring body is arranged at the anchoring end of the anchor rod; and the spiral anchoring body is a rod body the outside of which is provided with vortex filament. The double-anchoring anchor rod does not need to wait for the solidification time of an anchoring agent, can apply a proper initial anchoring force on a rock-soil body through one-step installation, can timely reinforce the rock-soil body, becomes a pre-strain anchor rod structure after the strength of the anchoring agent is reached later, and can play the role of the anchor rod to the maximum extent.
Description
Technical field
The present invention relates to the anchor pole that a kind of mining engineering supporting is used, be specifically related to a kind of dual-anchoring rod.
Background technology
Supporting has important function to the mine bolt technology to crossheading, and the speed of anchor bolt construction quality and anchor bolt construction is the focus that people are concerned about always, and anchor structure or pattern are most important in this field.The anchor pole that uses mainly contains following deficiency at present:
1) uses cement or resin anchor pole, need to wait for that cementing agent solidifies just can remove in the construction and installation process to bore and implement clamp nut technology as cementing agent.
2) anchor pole is installed the prestressing force that rear supporting plate applies and is had only seldom part of the body of rod.
Summary of the invention
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and providing a kind of can increase prestressing force and dual-anchoring rod quickly and easily is installed.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of dual-anchoring rod, comprise anchor rod body, pallet and nut, it is characterized in that the anchored end of described anchor rod body is provided with the Screw Anchor solid, described Screw Anchor solid is that the outside has the body of rod that revolves silk.
Described anchor rod body is reinforcing bar, steel strand or glass fiber reinforced plastic, and described Screw Anchor solid and anchor rod body connect as one.
Described Screw Anchor solid is connected on the body of rod or with the body of rod and is made into integration for revolving wire bond.
The silk that revolves of described Screw Anchor solid is single head or multi-head spiral line, and described helix is two kinds of forms continuous or that be interrupted.
The described spiral that revolves silk revolves silk and exceeds body of rod 1-4mm apart from being 4-25mm.
Described Screw Anchor solid is taper.
The present invention compared with prior art has the following advantages:
1, the revolving silk and can be carved into geotechnical body and form frictional resistance and play certain first anchor-hold of dual-anchoring rod in time reinforced structure, delays the unsettled unstability time limit of structure.
2, dual-anchoring rod can apply long prestressing force to anchor rod body, thereby makes the installation reliability of anchor pole improve greatly.
Below in conjunction with accompanying drawing the present invention is described in further detail.

The specific embodiment
Dual-anchoring rod as shown in Figure 1 comprises anchor rod body 2, anchor rod body 2 terminal pallet 3 and nuts 4 for being used to install and fix, and anchor rod body 2 front ends are Screw Anchor solid 1.Screw Anchor solid 1 is for having the body of rod that revolves silk 12, and anchor rod body 2 be a screw-thread steel, Screw Anchor solid 1 to revolve 12 direction be dextrorotation, the hand of spiral of anchor rod body 2 is left-handed.Anchor rod body 2 can also be other forms of steel, steel strand, glass fiber reinforced plastic, materials such as wood or bamboo.
Screw Anchor solid 1 connects as one with anchor rod body 2.
Screw Anchor solid 1 is welded on the body of rod for revolving silk 12.
The silk 12 that revolves of Screw Anchor solid 1 is the single head helix, and described helix is the continuous helical line.
The spiral that revolves silk 12 revolves silk 12 and exceeds body of rod 1mm apart from being 4mm.
Revolving silk 12 and can being carved into geotechnical body and forming frictional resistance and play certain first anchor-hold of dual-anchoring rod in time reinforced structure, delays the unsettled unstability time limit of structure.Dual-anchoring rod applies long prestressing force can for anchor rod body 2, thereby makes the installation reliability of anchor pole improve greatly.Adopt the inventive method can improve efficiency of construction, and use simple.
Dual-anchoring rod as shown in Figure 2 comprises anchor rod body 2, anchor rod body 2 terminal pallet 3 and nuts 4 for being used to install and fix, and anchor rod body 2 front ends are Screw Anchor solid 1.Screw Anchor solid 1 is a leptospira structure, and anchor rod body 2 is a screw-thread steel, and a direction of revolving of Screw Anchor solid 1 is left-handed, and the hand of spiral of anchor rod body 2 is dextrorotation.Anchor rod body 2 is a solid construction.Screw Anchor solid 1 and anchor rod body 2 are for being made into integration.
Screw Anchor solid 1 is an one with anchor rod body 2.
Screw Anchor solid 1 is made into integration with the body of rod for revolving silk.
The silk 12 that revolves of Screw Anchor solid 1 is the multi-head spiral line, the form of described helix for being interrupted, and multi-head spiral line precession speed is fast, and helix helps the resin explosive roll diffusion for being interrupted.
The spiral that revolves silk 12 revolves silk 12 and exceeds body of rod 4mm apart from being 25mm.
Screw Anchor solid 1 front end is a sharp cone distal.
The present invention can adapt to the DIFFERENT SOIL body according to the different parameters that revolves silk 12 sizes and spacing.
Revolving silk 12 and can being carved into geotechnical body and forming frictional resistance and play certain first anchor-hold of dual-anchoring rod in time reinforced structure, delays the unsettled unstability time limit of structure.Dual-anchoring rod applies long prestressing force can for anchor rod body 2, thereby makes the installation reliability of anchor pole improve greatly.Adopt the inventive method can improve efficiency of construction, and use simple.
