Description
Technical field
The utility model relates to a kind of tensioning equipment of carbon cloth, is applied to the prestressed stretch-draw of carbon cloth in prestressed carbon cloth reinforced technology.
Background technology
Carbon fiber cloth strengthening technology is to use the higher cementing agent of adhesion strength, on the carbon cloth surface that is attached to the concrete component that needs reinforcement tightly, carbon cloth and concrete component can tightly be combined, common participation work, can make the supporting capacity of reinforced concrete member and improved greatly by curved rigidity by pasting carbon cloth, thereby having played reinforcing, propose high-intensity effect.current widely used is common carbon fibers cloth reinforcing technique, due to some structural element for distortion and having relatively high expectations of preventing from ftractureing, common carbon cloth reinforced of simple use, can not play good effect, this will use prestressed carbon cloth reinforced technology, exactly before carbon cloth is affixed on concrete component, apply certain pulling force by certain equipment in advance, keep under prestressed state at carbon cloth, it is sticked on concrete component, enable the participation work common with concrete component, so greatly put forward the bending rigidity of structural element much of that, reduced distortion, thereby also suppressed carrying out of crack.But because carbon cloth is by much fibrous, thinner wider Cheng Buzhuan, the individual carbon fibers flexural capacity is relatively poor, be easy to be damaged, so the present prestress tensioning equipment of simple use at all can not the stretch-draw carbon cloth, this overcomes top difficulty with regard to requiring us to explore a kind of novel tensioning equipment.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, a kind of prestressed carbon cloth reinforced equipment of adaptation is provided, can applying prestressing force to carbon cloth.
For achieving the above object, the present invention adopts following technical proposals:
prestressed carbon cloth reinforced equipment, comprise the jack that is arranged in order, the carbon cloth rotation lock device, carbon cloth adjusting device and carbon cloth anchor plate, jack, the carbon cloth rotation lock device is fixed on fixed support, the bolt hole fastening with cloth component to be spread arranged on fixed support, the carbon cloth rotation lock device comprises the quadrangle horizontal support, quadrangle horizontal support one end is connected with jack by bolt, the other end is fixed wtih the carbon cloth lock shaft, the gap that allows carbon cloth to pass is arranged on the carbon cloth lock shaft, the two ends of carbon cloth lock shaft are provided with stings shaft gear, sting the shaft gear side and establish the gear clamp, establish in the termination, two ends of carbon cloth lock shaft and rotate the card cap.
Described carbon cloth adjusting device comprises support transverse slat, support riser, on the support transverse slat, adjusting bolt is arranged, and adjusting bolt can drive the adjusting bloom and move up and down.The triangle rail groove is arranged on the support riser.Described carbon cloth anchor plate is the rectangle steel plate, has on steel plate to hold the gap that carbon cloth passes, and there is bolt hole at the two ends, gap.
Carbon cloth is passed gap on the carbon cloth anchor plate, and reserve the length of ten centimeters left and right, then rotate under ten centimeters superjacent carbon cloths of carbon cloth that the carbon cloth anchor plate will reserve, form a self-locking state, then use bolt anchoring on the surface of concrete component the carbon cloth anchor plate, implement stretch-draw at the other end.With fixed support with bolt anchoring to concrete component, the middle gap vertically of rotation carbon cloth lock shaft, after being passed the gap, carbon cloth reserves the length of about five centimeters, so rotate the card cap with autowrench, rotate the moving carbon cloth lock shaft of card hatband, carbon cloth is wrapped on lock shaft uniformly, and during stretch-draw, carbon cloth will be fixed on lock shaft firmly like this.The effect of stinging shaft gear is to be along tooth when being wound around carbon cloth, can be good at rotating the carbon cloth lock shaft, is contrary tooth in the time of stretch-draw prestressing force, and the carbon cloth lock shaft can not rotate, and prestressed stretch-draw just can be implemented like this.The jack telescopic shaft is all stretched out, rotate the tension of lock shaft glue carbon cloth, begin stretch-draw after being ready to, control the size of stretch-draw prestressing force according to the number of degrees of jack meter reading, after stretch-draw is complete, rotate the adjusting bolt of carbon cloth adjusting device with spanner, drive moves up and down bloom and moves down, under the orientation of triangle rail groove, carbon cloth is pushed up the surface of concrete structure of reinforcing.
The present invention can be with the on-the-spot stretch-draw of carbon cloth, and with its stickup be anchored on concrete component, and is simple and convenient, adapts to the Practice of reinforcing of actual bridge engineering.
