Abstract
The utility model discloses an anchor device of an extrusion type carbon fiber anchor cable, which consists of a carbon fiber anchor cable (1) and a steel sleeve (2), wherein the anchoring section of the carbon fiber anchor cable (1) is provided with a layer of extruding sleeve (3), the steel sleeve (2) is sleeved on the extruding sleeve (3) and exerts radial stress, so the steel sleeve (2) and the extruding sleeve generate radial deformation to be connected onto the carbon anchor cable (3). The utility model has the advantages of not only high tensile strength, light weight and no corrosion, but also no creep deformation, good fatigue resistance, small thermal expansion coefficient, good corrosion resistance, easiness in installation and transportation, convenience in use and the like.
Description
Technical field
The utility model relates to a kind of squash type carbon fiber anchorage cable anchoring device, belongs to the anchor cable manufacture technology field.
Background technology
Anchor cable is the device that is used to reinforce rock mass in the 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, applies pulling force, to be reinforced between rock mass and the rock mass stability, produces compressive stress, thereby increases skid resistance; Or produce component upwards, thereby reduce sliding force.Reach the purpose of reinforcing rock mass.
Traditional anchor cable is a cable wire rope.The major defect of cable wire rope is: 1) weight is big, transportation, installation difficulty.For some high gradient slopes, because on-the-spot place is narrow, dangerously steep, there are not enough spaces to settle wherein equipment, traditional cable wire rope can't be installed and construct; 2) easy-to-rust.Although the measure of more existing at present control cable wire rope corrosions still can't fundamentally be stopped its corrosion phenomena.Particularly in some sea water intrusion stratum, pozzolan stratum, corrosion is especially serious.Given this,, have to regularly anchor cable be carried out antirust processing, even construct, change anchor cable again for key project.Increased a large amount of later stage engineering maintenance expenses.Therefore, the result of use of existing anchor cable still is not ideal enough.
Summary of the invention
The purpose of this utility model is: provide that a kind of intensity is higher, weight gentlier, can not corrosion and squash type carbon fiber anchorage cable anchoring device easy to use, to overcome the deficiencies in the prior art.
The utility model is achieved in that a kind of squash type carbon fiber anchorage cable anchoring device of the present utility model is made up of carbon fiber anchor cable and steel bushing, anchoring section at the carbon fiber anchor cable partly is provided with one deck extruded sleeve, steel bushing is enclosed within on the extruded sleeve, and apply radial pressure, make steel bushing and extruded sleeve produce radial deformation, thereby be connected on the carbon fiber anchor cable.
The above-mentioned steel bushing that is connected on the carbon fiber anchor cable by built-in extruded sleeve is the steel bushing of crimp.
Above-mentioned extruded sleeve has tube-in-tube structure certain flexibility and that copper metal, Al-alloy metal, nylon or plastic material that ductility is better, shear strength is higher are made for adopting.
Also be coated with one deck resin base class water proof compound protective layer at the two ends of above-mentioned steel bushing.
Owing to adopted technique scheme, the utility model adopts carbon fiber anchor cable and steel bushing to form squash type carbon fiber anchorage cable anchoring device, 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 is higher than steel.Therefore the utility model compared with prior art, the utility model not only has tensile strength height, in light weight, advantage that can not corrosion, but also tool does not have creep, fatigue durability is good, coefficient of thermal expansion is little, good corrosion resistance, be easy to installation and transportation, advantage such as easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Description of reference numerals: 1-carbon fiber anchor cable, 2-steel bushing, 3-extruded sleeve, 4-resin base class water proof compound protective layer.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment of the present utility model: a kind of squash type carbon fiber anchorage cable anchoring device of the present utility model is made up of carbon fiber anchor cable 1 and steel bushing 2, carbon fiber anchor cable 1 directly adopts existing carbon fibre bar material to make, during making, on the anchoring section surface partly of carbon fiber anchor cable 1, overlap employing and have certain flexibility, and ductility is better, the copper that shear strength is higher, aluminium alloys, nylon or plastic material are made the extruded sleeve 3 of tube-in-tube structure, the length of extruded sleeve 3 is made into length more than or equal to steel bushing 2, then steel bushing 2 is enclosed within on the extruded sleeve 3, in order to reach better bonding strength, after being connected carbon fiber anchor cable 1 on by built-in extruded sleeve 3 steel bushing 2, adopt the mode of extruding that steel bushing 2 is carried out radial compression, make steel bushing 2 and extruded sleeve 3 produce crimp simultaneously, can make the crimp steel bushing that is connected the steel bushing formation permanent deformation on the carbon fiber anchor cable by built-in extruded sleeve like this; In order to reach better waterproof and anticorrosion ability, adopt existing resin base class water proof glue material to cover last layer resin base class water proof compound protective layer 4 at the two ends of steel bushing 2.
