Abstract
The utility model discloses a carbon fiber anchor cable device, which comprises a stretch-draw section (1) which is made from carbon fiber ribs, and has two ends which are respectively and fixedly provided with a steel sleeve (2) for connecting an outer anchoring section or inner anchoring section. 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 carbon fiber anchor cable 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 carbon fiber anchor cable device easy to use, to overcome the deficiencies in the prior art.
The utility model is achieved in that a kind of carbon fiber anchor cable device of the present utility model, comprise the stretch-draw section, the stretch-draw section that its stretch-draw section is the carbon fibre bar material, and be fixed with the steel bushing that connects outer anchoring section or the use of interior anchoring section at the two ends of the stretch-draw section of carbon fibre bar material.
On the external surface of the stretch-draw section of above-mentioned carbon fibre bar material, scribble the stretch-draw segment protect layer of one deck resin base class water proof glue material.
On the end face of the fixing steel bushing in the stretch-draw section two ends of above-mentioned carbon fibre bar material, scribble the end face topping of one deck resin base class water proof glue material.
Owing to adopted technique scheme, the stretch-draw section that stretch-draw section of the present utility model is the carbon fibre bar material, and be fixed with the steel bushing that connects outer anchoring section or the use of interior anchoring section at the two ends of the stretch-draw section of carbon fibre bar material.The utility model has been abandoned cable wire rope structure used in the prior art fully.The carbon fibre bar material that the utility model adopted 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-stretch-draw section, 2-steel bushing, the stretch-draw segment protect layer of 3-resin base class water proof glue material, the end face topping of 4-resin base class water proof glue material.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment of the present utility model: the structural representation of a kind of carbon fiber anchor cable device of the present utility model as shown in Figure 1, this structure comprises stretch-draw section 1, during making, adopt the manufacturing materials of existing carbon fibre bar material as stretch-draw section 1, stretch-draw section 1 is made as the stretch-draw section 1 of carbon fibre bar material, and then produce steel bushing 2, and steel bushing 2 is enclosed within the two ends of the stretch-draw section 1 of carbon fibre bar material respectively, adopt the mode of extruding that steel bushing 2 is carried out radial compression then, or adopt bonding mode, it is pressed solidly or is bonded on the two ends of stretch-draw section 1 of carbon fibre bar material, the steel bushing 2 at these two ends outer anchoring section of connection or the interior anchoring section that promptly can be used as anchor cable uses so in use; In order to reach better waterproof and decay resistance; during making; on the external surface of the stretch-draw section 1 of carbon fibre bar material, adopt existing resin base class water proof glue material to be coated with the stretch-draw segment protect layer 3 of last layer resin-based class water proof glue material, and be coated with the end face topping 4 of last layer resin-based class water proof glue material on the end face of the steel bushing 2 that presses solidly at stretch-draw section 1 two ends of carbon fibre bar material.
When using the utility model, steel bushing 2 of the present utility model can be connected with existing ground tackle, its connected mode can adopt modes such as screw thread, wedge intermediate plate, welding to connect.And then anchor cable construction technology is routinely carried out anchoring, installation gets final product.
Claims (3)
1. carbon fiber anchor cable device, comprise stretch-draw section (1), it is characterized in that: stretch-draw section (1) is the stretch-draw section of carbon fibre bar material, and is fixed with the steel bushing (2) that connects outer anchoring section or the use of interior anchoring section at the two ends of the stretch-draw section (1) of carbon fibre bar material.
