Specific embodiment
Fig. 1 represents the outward appearance of carbon fiber rope.Fig. 2 is the exploded perspective view of carbon fiber rope.Fig. 3 to Fig. 5 is edge respectively The III-III line of Fig. 1, IV-IV line, the amplification view of the carbon fiber rope of V-V line.
Carbon fiber rope 1 is being in six roots of sensation side line 3 (3a~3f) structure of twisted state by a heart yearn 2 and about Become (1 × 7 structure).Observe from section, carbon fiber rope 1, heart yearn 2 and side line 3 are respectively provided with the shape of circular.In addition, Observe from section, the heart is configured with heart yearn 2 to carbon fiber rope 1 wherein, and be provided with six roots of sensation side line 3 in the way of surrounding heart yearn 2. Carbon fiber rope 1 have such as 5mm~20mm about diameter.
Heart yearn 2 and side line 3 are all long by many for example tens thousand of that are impregnated with thermosetting resin (for example, epoxy resin) 5 It is circular rope yarn that carbon fiber 4 harness of shape becomes section, therefore the overall carbon fibre including hundreds thousand of about of carbon fiber rope 1 Dimension 4.Every carbon fiber 4 is very thin, has such as 5 μm~7 μm of diameter.Can also be by thermosetting resin 5 will be impregnated with Bundle pricked by many carbon fibers 4, and by stranded for this carbon fiber bundle many, forms heart yearn 2 and side line 3 respectively.Heart yearn 2 and side line 3 also may be used To say the being rope yarn that carbon fibre composite (CFRP) (Carbon Fiber Reinforced plastics) is made.
For heart yearn 2 and side line 3, in the present embodiment using the rope yarn of identical thickness (area of section).But can also Using or than heart yearn 2 thick side line 3 thinner than heart yearn 2.By the radical of different carbon fibers 4, can arbitrarily adjust heart yearn 2 Thickness with each side line 3.
For the heart yearn 2 constituting carbon fiber rope 1 and side line 3, all use and heat is previously applied to thermosetting resin 5 and makes The rope yarn of the state of its solidification.That is, by the heart yearn 2 in the state of solidifying in the thermosetting using thermosetting resin 5 Around, configure the side line 3 in the state of solidifying also with the thermosetting of thermosetting resin 5 and become stranded State, make carbon fiber rope 1.Thermosetting resin 5 due to each heart yearn 2 and each side line 3 solidifies, therefore in heart yearn 2 and its The side line 3 of surrounding and side line 3 allow suitable sliding each other.
With reference to Fig. 2,6 side lines 3 becoming stranded state around heart yearn 2 are all fixed to helical form, separately in advance On the one hand, heart yearn 2 does not have spiral helicine sizing.Need not polylogia, the spiral-shaped of side line 3 is by thermosetting resin 5 thermosetting Sizing before change.The lay pitch of the spiral helicine sizing of each side line 3 is roughly the same, and the spiral internal diameter of each side line 3 and heart yearn 2 Diameter roughly equal.
Here, in each side line 3, being there is the part being finalized in the way of partly outside slightly expansion and (hereinafter referred to as expand Part).In carbon fiber rope 1 shown in Fig. 1, slightly emphatically show dilation 3A~3D everywhere.
With reference to Fig. 3, when section observes the part with dilation 3A, in 6 around heart yearn 2 piece side line 3a~3f 1 (side line 3a) is not contacted with heart yearn 2, outwards misplaces away from heart yearn 2.In the way of there is this dislocation, to side line 3a in advance Shaped.By way of side line 3a is away from heart yearn 2, thus ensure that between heart yearn 2 and side line 3a inner space (non-connects Contact portion is divided) 11.
Because heart yearn 2 and side line 3 section are circle, therefore certainly exist discontiguous between heart yearn 2 and side line 3 Partly (space being for example, in figure 3, general triangular by the section that heart yearn 2, side line 3c, side line 3d are formed) is (using accompanying drawing Labelling 20 represents), but described inner space 11 in this specification does not imply that the space 20 that this section is general triangular, And refer to the space between the heart yearn 2 that guaranteed by the sizing that side line 3 is carried out in advance and side line 3.By assuring that it is internal empty Between 11, two sections are that the space 20 of general triangular links together.
In figure 3, side line 3a is contacted with two side line one of 3b, 3f side line 3f positioned at its both sides, but with another One side line 3b does not contact, and (in the way of there is this dislocation, side line 3a is carried out in advance to the direction dislocation away from side line 3b Sizing).By way of side line 3a is away from side line 3b, thus ensure that gap 12 between side line 3a and side line 3b.
With reference to Fig. 4, when section observes the part with other dilations 3B, the six roots of sensation side line 3a around heart yearn 2~ Two (side line 3e, 3f) in 3f are not contacted with heart yearn 2, thus ensure that inner space between heart yearn 2 and side line 3e, 3f 11.Because side line 3e, 3f are adjacent, therefore two inner spaces 11 are continuous, and its result is to define broad inner space. In addition, though other side lines 3c is contacted with heart yearn 2, but this side line 3c is divided with two side line 3b, 3d both sides positioned at its both sides From thus ensure that gap 12 respectively in the both sides of side line 3c.
In the diagram, inner space 11 is illustrated as closing space, but the inner space 11 not sky with outside cut-off completely Between, but the open space with ft connection.That is, the inner space 11 guaranteeing between heart yearn 2 and side line 3 with carbon fiber rope It is continuous that two adjacent side lines 3 of the other positions of the length direction of rope 1 separate the above-mentioned gap 12 being guaranteed.By gap 12, Inner space 11 and ft connection.
With reference to Fig. 5, when section observes the part with dilation 3C, 3D, in the six roots of sensation side line 3 around heart yearn 2 Four (side line 3b, 3c, 3e, 3f) does not contact with heart yearn 2 it is ensured that inner space 11.In addition, between side line 3a and 3b, side Gap 12 is ensure that between line 3c and 3d, between side line 3e and 3f, between side line 3f and 3a.
So, carbon fiber rope 1 is according to the difference of the position as section, the position in inner space 11 and gap 12 and Quantity is different.But, according to the difference of section and position, both there are the feelings that inner space 11 and gap 12 are not in completely Condition, conversely, the all-round six roots of sensation side line 3 that also likely to be present in heart yearn 2 does not contact the situation of heart yearn 2.In addition, as Fig. 3~Fig. 5 institute Show, the size in the inner space 11 that section illustrates and gap 12 (the distance between heart yearn 2 and side line 3, adjacent side line 3 it Between distance) be diversified.The degree of the multiple dilation 3A~3D of this expression is diversified.Additionally, it is fine in carbon There is not great dilation (inner space 11 and gap 12), thus not there being the stranded shape of substantial damage in dimension rope 1 The situation of state.
Above-mentioned dilation is concatenated to form on the length direction of carbon fiber rope 1.That is, with regard to heart yearn 2 and Duo Gen side , above-mentioned side line 3 and contacts the contact portion of above-mentioned heart yearn 2 (do not have internal sky in the longitudinal direction repeatedly in each side line of line 3 Between 11 part) and above-mentioned side line 3 do not contact the non-contact part (there is the part of inner space 11) of above-mentioned heart yearn 2.With Sample ground, to adjacent side line 3 each other for, contact portion (not having the part in gap 12) also occurs in the longitudinal direction repeatedly And non-contact part (there is the part in gap 12).
Dilation can be arranged it is also possible to be randomly provided every predetermined distance on the length direction of each side line 3.To institute For some side lines 3, can be in the longitudinal direction with identical interval setting dilation it is also possible to make for each side line 3 Dilation is different at the interval of length direction.Dilation scattering device in carbon fiber rope 1, in the length of carbon fiber rope 1 On degree direction, inner space 11 and gap 12 dispersion exist.
As described above, carbon fiber rope 1 is solidified due to the thermosetting resin 5 of heart yearn 2 and each side line of side line 3, therefore exist Between heart yearn 2 and side line 3, side line 3 allow sliding each other, and then due to having inner space 11 and gap 12, therefore by The flexure of appropriateness is produced, thus operability is more excellent when being curved.The spool of path can be wound into and densification, operation The operation at scene also will become light.Carbon fiber rope 1 is suitable for being used for example as the core of the elongate objects such as power transmission line.
In addition, carbon fiber rope 1 can be used as the reinforcement material of such as concrete construction.Carbon fiber rope 1 is embedded in When in the concrete (newly-laid concrete) before solidification, with adjacent side line 3, gap 12 each other enters concrete for entrance In carbon fiber rope 1.Enter from gap 12 and guaranteed between the concrete entrance heart yearn 2 of the inside of carbon fiber rope 1 and side line 3 Inner space 11, as a result, contact area between carbon fiber rope 1 and concrete becomes big.But, according to newly-laid concrete Viscosity, inner space 11, the difference of the size in gap 12 etc. it is also possible to concrete is not completely filled with inner space 11, but It is on the basis of concrete is contacted with the outer peripheral face (surface) of carbon fiber rope 1, also can occur in the inside of carbon fiber rope 1 Contact with concrete, it is achieved that the increase of the contact area between concrete and carbon fiber rope 1.Thus, for example, with Reinforcing bar is compared, and adhesive stress degree can be greatly improved, and with higher fixed efficiency, carbon fiber rope 1 can be fixed on concrete In.Concrete construction includes bridge grider, bridge pier, bridge wall railing, protection walls etc..
Fig. 6 be represent transverse axis be sliding displacement (mm), the longitudinal axis be adhesive stress degree (N/mm2) concrete pull-out test knot The curve chart of fruit.Solid line in curve chart represents the result of the test of above-mentioned carbon fiber rope 1, and dotted line represents do not there is internal sky Between 11 and gap 12 carbon fiber rope result of the test.Constitute the diameter of the heart yearn of rope and side line, radical and structure, with And the embedment length (attachment length) in concrete is measured at identical conditions.
" the continuous fiber reinforcement material based on pull-out test and coagulation that concrete pull-out test is formulated according to building association Adhesive strength test method between soil " is carried out.In this experiment, it is produced on the shape that the two ends of carbon fiber rope externally protrude It is embedded with the concrete block of intermediate portion under state.Using cupping machine, to from the outwardly directed carbon in one end of concrete block Fibrecord applies tensile load with the load rate specifying, outwardly directed to the other end from concrete block using displacement meter The displacement (sliding displacement) of carbon fiber rope measures.
Adhesive stress degree τ (N/mm2) calculated using below equation.
Adhesive stress degree τ=P/u L
Wherein, P represents tensile load (kN), and u represents the nominal circumference (mm) of carbon fiber rope, and L represents with respect to coagulation The attachment length (mm) of soil block.
Can be seen that from the result of Analysis of Concrete Tensile test and there is no inner space 11 and the carbon fiber rope in gap 12 Adhesive stress degree (dotted line) compare, the adhesive stress degree (solid line) of above-mentioned carbon fiber rope 1 is greatly improved, and concrete is fixed Efficiency is higher.
The sizing degree (degree of the constraint realized by side line 3) of the side line 3 in carbon fiber rope 1 can use carbon fiber The diameter D of rope 1, the diameter σ of the heart yearn 2 of composition carbon fiber rope 11Diameter σ with side line 32, by D/ (σ1+2σ2)×100 (%) (hereinafter referred to as sizing rate) represents.If there is the sizing rate of about 100.1~105 (%), carbon fiber rope 1 quilt The flexure of appropriateness can be produced, thus concrete fixed efficiency also can improve when being curved.But, fix paying attention to concrete It is also possible to many side line 3 sizings are made it have bigger example in the case that efficiency will improve concrete fixed efficiency further As 110% about sizing rate.
In the above-described embodiment, for by making thermosetting resin 5 impregnate the wire harness of many carbon fibers 4 and by it Apply heat and make it solidify the heart yearn 2 obtaining and side line 3 and constitute the example of carbon fiber rope 1 to be illustrated, but can also generation Use thermoplastic resin (for example, polyamide) for thermosetting resin 5.Alternatively, it is also possible to replace carbon fiber to use glass Fiber, boron fibre, aramid fiber, polyethylene fibre, PBO (polyp-phenylenebenzobisoxazole) fiber etc. other Synthetic fibers.
