Abstract
The utility model discloses a threaded carbon fiber anchor cable anchoring device, which consists of a carbon fiber anchor cable (1) and a steel sleeve (2). An aramid fiber threaded layer (3) is arranged on an anchoring section of the carbon fiber anchor cable (1), the steel sleeve (2) is provided with inner threads matching with threads of the aramid fiber threaded layer (3) on the carbon fiber anchor cable (1) and is connected onto the aramid fiber threaded layer (3) of the carbon fiber anchor cable (1) via the inner threads, a glue injecting hole (4) and a glue outlet hole (5) which are communicated with an inner threaded hole of the steel sleeve (2) are arranged on the surface of the steel sleeve (2), and resin matrix steel bonding glue is fully filled in both the glue injecting hole (4) and the glue outlet hole (5). The threaded carbon fiber anchor cable anchoring device has the advantages of high tensile strength, light weight, rust resistance, zero creep deformation, fine fatigue durability, low thermal expansion factor, fine corrosion resistance, easiness in installation and transportation, convenience in use and the like.
Description
Technical field
The utility model relates to a kind of screw-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 through 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, difficult installation.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 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 the utility model is: provide that a kind of intensity is higher, weight gentlier, can not corrosion and screw-type carbon fiber anchorage cable anchoring device easy to use, to overcome the deficiency of prior art.
The utility model is achieved in that a kind of screw-type carbon fiber anchorage cable anchoring device of the utility model does; This screw-type carbon fiber anchorage cable anchoring device 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 aramid fiber screw thread layer; Be provided with on the steel bushing with the carbon fiber anchor cable on the internal thread that matches of the screw thread of aramid fiber screw thread layer, and steel bushing is connected on the aramid fiber screw thread layer of carbon fiber anchor cable through internal thread; On the surface of steel bushing, be provided with the hole for injecting glue and the plastic hole that communicate with the internal thread hole of steel bushing, and in hole for injecting glue He in the plastic hole, all filled with resin base class steel bonding glue.
Above-mentioned hole for injecting glue and the plastic hole that is located on the steel bushing is respectively 2～10, and respectively by equidistantly being arranged on the steel bushing.
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 screw-type carbon fiber anchorage cable anchoring device, and the utility model has been abandoned cable wire rope structure used in the prior art fully.The carbon fiber anchor cable of the utility model adopts existing carbon fibre bar material to be made.The carbon fibre bar material is the excellent new material of a kind of mechanical property, 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.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
The embodiment of the utility model: a kind of screw-type carbon fiber anchorage cable anchoring device of the utility model is made up of carbon fiber anchor cable 1 and steel bushing 2; As shown in Figure 1; During making; Partly produce one deck aramid fiber screw thread layer 3 at the anchoring section of carbon fiber anchor cable 1; And produce on the steel bushing 2 with carbon fiber anchor cable 1 on the internal thread that matches of the screw thread of aramid fiber screw thread layer 3; On the surface of steel bushing 2, produce simultaneously the hole for injecting glue 4 and plastic hole 5 that communicate with the internal thread hole of steel bushing 2, the quantity of hole for injecting glue on the steel bushing 24 and plastic hole 5 be controlled at 2～10 scope respectively, and with hole for injecting glue 4 and plastic hole 5 respectively by equidistantly being arranged on the steel bushing 2; Be connected steel bushing 2 on the aramid fiber screw thread layer 3 of carbon fiber anchor cable 1 through internal thread then; And adopt existing resin base class steel bonding glue to pour into through hole for injecting glue 4, in when perfusion, when in the plastic hole 5 when having observed glue and flowing out, promptly the shutoff plastic hole 5, can make like this in the hole for injecting glue 4 with in the plastic hole 5 and all fill with resin base class steel bonding glue; In order to reach better water resistance, can cover one deck at the two ends of steel bushing 2 and adopt resin base class water proof compound protective layer 6 that existing resin base class water proof glue makes.
