Abstract
The utility model relates to a bolt bamboo anchor rod used for supporting the laneways of mine. Rod bodies are composed of two bamboo sheets, and wedges and metallic screw rods are bonded among the rod bodies. The bolt bamboo anchor rod can be used for stirring resin or cement cartridge, a bolt fastening structure is utilized, and thus the supporting anchoring force and the anchoring force of the anchor rod are enhanced. Metallic anchor rods can be replaced, a large amount of steel is saved, and the cost of the anchor rod and workers' labor intensity are reduced. The bolt bamboo anchor rod has easy installation and safe use.
Description
The utility model is a kind of anchor pole, is used for the supporting in tunnel under the mine.
For many years, many people are being engaged in the development of bamboo anchoring-bolt always, but bamboo anchoring-bolt still adopts the chock anchoring and locks so far, because that power is retouched in this structure anchor power and holder is too little, along with the pressure increase of shaft deepening ground, it just can't be competent at support work.Though the present full anchor of also useful mortar, but the bar afterbody is still locked with chock, the problem that anchor support force is too little is still unresolved, do not bring into play the advantage of bamboo height tensile strength, and it can not stir anchoring agent powder stick, can't make anchored force that by a relatively large margin raising is arranged, thereby this bamboo anchoring-bolt still can't competently be pressed the support work in big tunnel.Like this, ground presses bigger tunnel have to adopt anchor metal, consumes great deal of steel, and the manufacturing process complexity of anchor metal, and the cost height has been wasted a large amount of manpower and materials.
The purpose of this utility model is to overcome the deficiency of existing bamboo anchoring-bolt technology, and design that a kind of anchored force is strong, anchor support force big, first anchor support force arranged, the bamboo anchoring-bolt of pressure is bigger with can be used for tunnel substituted metal anchor pole.
The utility model is achieved in that by two bamboo chips and constitutes the body of rod, is characterised in that, be bonded with screw rod between the body of rod and fill out wedge, body of rod two ends can be twined with the glass fabric that is soaked with resin, gain in strength, be bonded with back-up ring on the body of rod, prevent anchoring agent outflow when being used in the end anchor.
Because the utility model bulk strength is higher, adopted bolt fastening structure again, thereby anchor pole can connect agitator stirring anchoring agent, that is to say and to carry out anchoring with resin or cement-roll, thereby increased substantially anchored force, the structure of bolton has also improved anchor support force greatly, along with screwing of nut, supporting plate will be held tightly by anchoring body and produce anchor support force just, and first anchor support force is not less than 15KN.Industrial experiment shows, the tension pull out force of anchor pole reaches more than the 40KN, and is safe and reliable, presses bigger back production and development heading on ground, can the substituted metal anchor pole, every cover anchor pole can be saved steel 86%, and cost reduces by 40%, during skyhook, the stirring of anchoring agent, nut fastening, all adopt mechanized operation, improved work efficiency, reduced working strength of workers.
Accompanying drawing 1 is a structural representation of the present utility model, and accompanying drawing 2 is a user mode schematic diagram of the present utility model.1 packing ring, 2 supporting plates, 3 screw rods, 4 bodies of rod, 5 fill out wedge, 6 back-up rings, 7 nuts, 8 by anchoring body, 9 anchoring agent, 10 steel band beams.
The utility model is described in further detail below by accompanying drawing.
The thickness of bamboo chip is in 7.5 millimeter, wide 25 millimeter, and just sectional area is about 188 square millimeters.To fill out wedge and screw rod is bonded between the body of rod with cementing agent, filling out wedge is the wedge shape bamboo product, and its effect has been transition and has saved cementing agent, fills out the thickness and the width of wedge bottom, threaded flat tongue end unanimity.The bonding end of screw rod is flat ligule, for guaranteeing adhesion strength, on the adhesive surface netted groove can be arranged.Screw rod is made with the smooth bar of diameter 14-20 millimeter, an end thread cutting, and an end forges into flat ligule.For guaranteeing the bulk strength of the body of rod, bamboo chip can twine one section with the glass fabric that is soaked with resin at its two ends after bonding, and for improving the effect that stirs the anchoring agent, the bamboo chip anchored end can become dovetail shaped.During use, the dust in the bolthole is removed totally, anchoring agent powder stick is put into the hole, then anchor pole is inserted in the hole, after sending to powder stick at the bottom of the hole, drive anchor pole with agitator and rotate, after the anchoring agent is solidified, spread protecting wire net, put steel band beam or reinforcing bar beam, supporting plate, packing ring, last fastening nut.The cementing agent usable resins class cementing agent of bamboo chip and screw rod.
Claims (3)
1, a kind ofly constitutes the bolt bamboo anchoring-bolt of the body of rod, it is characterized in that be bonded with screw rod (3) between the body of rod (4) and fill out wedge (5), the anchored end of the body of rod is bonded with back-up ring (6) by two bamboo chips.
By the described bolt bamboo anchoring-bolt of claim 1, it is characterized in that 2, screw rod bonding end can have netted groove for flat ligule on the adhesive surface.
3, by the described bolt bamboo anchoring-bolt of claim 1, it is characterized in that the anchored end of bamboo chip can be a dovetail shaped.
