Technical field
The utility model relates to a kind of hot extrusion type carbon fiber anchor cable anchoring device, belongs to the anchor cable manufacture technology field.
Background technology
Anchor cable is the device that is usually used in reinforcing rock mass in geotechnical engineering, and it is to be reinforced rock mass by an end is fixed in, and the other end is anchored in the anchor cable of rock mass stability, apply pulling force, to be reinforced between rock mass and rock mass stability, to produce compressive stress, thereby increase skid resistance; Or produce component upwards, thus reduce sliding force, can reach like this purpose of reinforcing rock mass.
Traditional anchor cable is cable wire rope.The major defect of cable wire rope is: 1) weight is large, transportation, installation difficulty.For some high gradient slopes, dangerously steep due to on-the-spot narrow space, do not have enough spaces to settle wherein equipment, this traditional cable wire rope can't be installed and construct; 2) easy-to-rust is although the measure of more existing control cable wire rope corrosions at present still can't fundamentally be stopped its corrosion phenomena.Particularly in some sea water intrusions stratum, pozzolan stratum, corrosion is especially serious.Given this, for key project, have to regularly anchor cable be carried out antirust processing, even again construct, change anchor cable.Increased a large amount of later stage engineering maintenance expenses.For addressing this problem, carbon fiber anchor cable has appearred in the prior art, although this carbon fiber anchor cable has solved the corrosion problem, due to the anchoring section structure of existing carbon fiber anchor cable often adopt be
Anchoring sectionPart arranges screw thread and passes through
On anchoring sectionBeing threaded one is provided with the steel bushing structure of internal thread, and this structure not only exists the making hard problem, but also exists the problem that tensile strength in use can reduce; Existing this carbon fiber anchor cable is when just bringing into use, its tensile strength can also meet the demands, but in use for some time, because the coefficient of deformation of the coefficient of deformation of steel bushing and carbon fiber anchor cable anchoring section is inconsistent, and being connected frictional force and can not adjusting of steel bushing and carbon fiber anchor cable anchoring section, so in use for some time, the tensile strength of the carbon fiber anchor cable of this structure will reduce, and has heavily affected the result of use of whole carbon fiber anchor cable.Therefore, existing anchor cable or not ideal enough.
Summary of the invention
The purpose of this utility model is: provide a kind of and make easily, intensity is higher, and can guarantee that tensile strength in use can not reduce and lightweight, can not corrosion, hot extrusion type carbon fiber anchor cable anchoring device easy to use, to overcome the deficiencies in the prior art.
the utility model is to consist of like this: a kind of hot extrusion type carbon fiber anchor cable anchoring device of the present utility model is, this device comprises the carbon fiber anchor cable that is provided with anchoring section, the diameter of anchoring section is greater than the diameter of carbon fiber anchor cable, engaging has two watts of shape steel bushings on anchoring section, be provided with the anti-slip veins of dentation on the inner arc surface of two watts of shape steel bushings, and anti-slip veins is embedded in anchoring section, be provided with screwed hole on a watt of shape steel bushing, be provided with the sunk screw through hole corresponding with the screwed hole position on another watt shape steel bushing, sunk screw is connected with screwed hole by the sunk screw through hole, and two watts of shape steel bushings are connected as one.
4～10 millimeters of the Circularhole diameters that the diameter of above-mentioned anchoring section forms greater than the inner arc surface that is fastened togather by two watts of shape steel bushings.
Be coated with one deck resin base class water proof compound protective layer at the two ends of the above-mentioned watt shape steel bushing that is fastened togather.
Be reserved with the gap of 1～3 millimeter between above-mentioned two watts of shape steel bushings that connect as one by sunk screw.
Owing to having adopted technique scheme, the utility model adopts carbon fiber anchor cable and watt shape steel bushing to form heating-anchor device of extrusion type carbon fiber anchor cable, and the utility model has been abandoned cable wire rope structure used in the prior art fully.Carbon fiber anchor cable of the present utility model adopts existing carbon fibre bar material to be made.The carbon fibre bar material is a kind of new material of mechanical property excellence, and its proportion is less than 1/4 of steel, and tensile strength is 7～9 times of steel, and generally all more than 3500Mpa, tensile modulus of elasticity is 23000～43000Mpa, also higher than steel.In addition, the utility model adopts passes through the structure that screw connects as one two watts of shape steel bushings, in use, even produce the otherness distortion between carbon fiber anchor cable anchoring section and watt shape steel bushing, this distortion can be eliminated by tightening sunk screw easily.Due to being connected frictional force and can not reducing between carbon fiber anchor cable anchoring section of the present utility model and watt shape steel bushing, so its tensile strength in use can not produce too large variation.Therefore, the utility model compared with prior art, the utility model not only have advantages of make easily, intensity is higher, and can guarantee that in use tensile strength can not reduce, but also have lightweight, can not corrosion, the advantage such as easy to use.
