Description
Technical field
The utility model relates to a kind of tensioning equipment, is specifically related to a kind of novel pre-stressed carbon cloth tensioning equipment.
Background technology
Existing to concrete cylindrical carry out reinforcing adopt carbon cloth, but common carbon fibers cloth just plays the intensity less than 20% when tensile reinforcement is surrendered, after only having reinforcement yielding, its high powerful feature competence exertion out, but now the deflection deformation of component may be very large, fracture propagation may be relatively more serious, and such component can not meet the normal requirement used.Non-prestressed carbon cloth reinforced method improves little to the rigidity of component, effectively cannot suppress deflection deformation and the fracture propagation of component.The shear strength of binding material is certain, and along with the increase of external load, the shear stress that cross section is transmitted constantly increases, and shear strain constantly increases, and carbon cloth and concrete generation stripping damage, also make the intensity of carbon cloth not be fully used.
In order to give full play to the advantage of carbon cloth high strength, use for reference the general principle of prestressed reinforced concrete construction technology, domestic and international researcher proposes carbon cloth Shi Hanzhang, then pastes the surface of component, namely prestressed carbon cloth reinforced.Current existing research proves, prestressed carbon cloth can play the feature of high-strength light better, cracking load and the yield load of component can be improved comparatively significantly, alleviate during common carbon fibers cloth is reinforced the response lag problem of relatively giving prominence to, the growth of effective restriction reinforcement stresses, reduces width and the deflection deformation in crack.China Patent No. is 201120008128.4, publication date is the utility model on August 17th, 2011, patent discloses a kind of high-strength fiber material self-locking anchor device, this patent adopts two anchor heads to apply stretching force to carbon cloth, although this patent applies predetermined prestressing force to carbon cloth before making carbon cloth before not pasting on concrete cylindrical in advance, and be pasted on concrete cylindrical under the state keeping this prestress value, realize the reinforcing to concrete cylindrical, although this patent improves the bearing capacity of concrete cylindrical and reduces concrete cylindrical at the crack width normally used under duty and deflection deformation, but, because the carbon cloth in this patent is pasted onto in the middle part of the anchor head of symmetrical two halves composition by adhesive, this just causes anchoring procedure complex procedures, lose time and manpower, the problem that anchoring cost is high.
Utility model content
The utility model is for solving existing carbon cloth tensioning equipment, and stretching process operation is too complicated, loses time and manpower, and the problem that cost is high, and then a kind of novel pre-stressed carbon cloth tensioning equipment is proposed.
The utility model is the technical scheme taked that solves the problem: the novel pre-stressed carbon cloth tensioning equipment of one described in the utility model comprises two bolts, two nuts and four fixture blocks, fixture block is by fixture block top, make with fixture block portion integral in the middle part of fixture block, medial surface in the middle part of fixture block is provided with multiple sawtooth, every two fixture blocks are oppositely arranged, and the sawtooth complete engagement formation fixture block assembly in the middle part of two fixture blocks, two fixture block assembly side-by-side parallel are arranged, each fixture block top is provided with a upper installing hole, each fixture block bottom is provided with a lower installing hole, the central axis of upper installing hole and the central axis of lower installing hole be arranged in parallel along the thickness direction of fixture block, screw bolt passes installing hole being fixed by nut on each, each lower installing hole of another screw bolt passes is also fixed by nut.
The beneficial effects of the utility model are: the utility model structure is simple, easy to operate, carbon cloth is wrapped in the centre of fixture block assembly, due to fixture block inside middle portion face being provided with multiple sawtooth, add the frictional force between fixture block and carbon cloth, firm for carbon cloth can be clamped, do not need in site operation to use adhesive to paste, operation is simple, save time and manpower, cost reduces 10%, two fixture block assemblies are wound around respectively the two ends of carbon cloth, and give carbon cloth prestressing force, the middle part of carbon cloth is wrapped on concrete cylindrical, bolt is inserted in upper installing hole on each fixture block and lower installing hole respectively, by the elasticity of synchronous adjustment two nuts, carry out stretch-draw carbon cloth, stretching force is even, stretch-draw effect is good.
