Description
Technical field
The utility model relates to a kind of tabletting type ground tackle, particularly relates to a kind of carbon fiber board prestress tension tabletting type ground tackle.
Background technology
Along with the fast development of society, require more and more higher to the bearing capacity of old concrete component self and anti-fatigue performance, in order to extend the application life of concrete component, general employing is high to concrete base component sticking strength, volume is conducted oneself with dignity, and little material carries out prestressed reinforcement, thus the generation of constraint transverse crack and development, improve self bearing capacity and service life.Carbon fiber board is a kind of tensile strength high (2400MPa), modulus of elasticity and steel close, the engineering construction new reinforced material that quality is light.Due to the performance that carbon fiber board is outstanding, it is widely used in structure strengthening and rebuilding engineering, but the elongation rate of carbon fiber board is larger, when being used in steel concrete bending resistance component, often the rate of utilization of strength of carbon fiber board does not reach 20% of normal intensity, therefore makes carbon fiber can not give full play to its due effect.A large amount of theory analysises and experimental study show, carbon fibre material Shi Hanzhang generally adopts bonding adhesive stickup to be anchored in strenthening member, due to the physical characteristic that carbon fibre material itself has, such mounting method is difficult to the requirement of strength reaching carbon fibre material, thus also can reduce the application life of girth member, because glue antiageing effect and durability are relatively poor.And in stretching process, construction is complicated, and the safety factor in work progress is relatively low.To the tabletting type ground tackle that carbon fiber board needs functional performance excellent by stretch-draw to its Shi Hanzhang, this ground tackle requires to include: the power on (1) compressing tablet must be applied to uniformly by pressure workpiece, thus makes its ground tackle inside reach a chucking power; (2) ground tackle itself must have sufficiently high intensity, simple structure, easy construction, and operating efficiency is high; (3) ground tackle can repeat stretch-draw, and the friction factor improving ground tackle self increases the stiction to workpiece.Therefore need one to have and uniform normal pressure is applied to carbon fiber board, and simple structure, lightly to reuse, carbon fiber board prestress tension compressing tablet ground tackle that operating efficiency is high, to expand the scope of application of carbon fiber board in engineer applied and to improve its performance in actual applications.
Summary of the invention
The purpose of this utility model is to provide a kind of carbon fiber board prestress tension tabletting type ground tackle, carbon fiber board surface is made to be subject to uniform normal pressure, anti-skid construction on this normal pressure and ground tackle base plate and ground tackle pressing plate makes to define frictional force between carbon fiber board and ground tackle, frictional force limits carbon fiber board and is pulled out ground tackle by stretching force, thus the effect of effective anchoring is reached, and this ground tackle simple structure, lightly to reuse, operating efficiency is high, to expand the scope of application of carbon fiber board in engineer applied and to improve its performance in actual applications.
For achieving the above object, technical solution of the present utility model is: a kind of carbon fiber board prestress tension tabletting type ground tackle, it is characterized in that: it comprises base plate 1, pressing plate 2, top pressure screw 3, cover plate 4, base plate 1, pressing plate 2 are connected by connecting screw 5 with the two ends of cover plate 4, the one side of described base plate 1 and pressing plate 2 is all carved with lines or indentation or groove or pit, cover plate 4 is also provided with top pressure screw 3.
Described top pressure screw 3 is hexagon socket head cap screw, and its quantity is at least 1.
The beneficial effects of the utility model are: when 1, adopting ground tackle compressing tablet pressure holding carbon fiber board, are easy to produce stress concentration phenomenon at carbon fiber board, cause carbon fiber board to rupture when stretch-draw, thus make to can not get safety guarantee in construction process.The axial compression that this carbon fiber board prestress tension ground tackle produces with top pressure screw, then top pressure screw produce axial compression under the effect by ground tackle pressing plate by stress equilibrium be distributed to by pressure carbon fiber board each position, carbon fiber board surface is made to be subject to uniform normal pressure, reach minimizing stress to concentrate, prevent carbon fiber board from rupturing when stretch-draw.
2, tabletting type ground tackle is in pressure holding process, the axial compression produced due to top pressure screw is excessive, ground tackle cover is made to produce lateral deformation, carbon fiber board more may be caused to be shifted to an earlier date pressure break, reduce the tension ability of carbon fiber board entirety, do not reach prestressing force requirement, for the number of times more reducing use ground tackle, thus improve the cost of whole material.This carbon fiber stretch-draw tabletting type ground tackle arranges the anti-skid constructions such as lines, indentation, groove, pit by compressing tablet pressing plate contact carbon fiber board face, friction factor is increased by these antiskid components, when pressure is constant, friction factor is larger, the frictional force produced is also larger, thus effectively raise the utilization rate of ground tackle, decrease the lateral deformation of ground tackle.
3, tabletting type ground tackle is in pressure holding process, because compressing tablet position easily offsets, causes prestressing force suffered by carbon fiber board not concentrated, and is easily pulled out by carbon plate in stretching process.The pull-type ground tackle of this carbon fiber prestressing force, reserves screw attachment holes at film pressure plate, then by screw, film pressure plate and ground tackle is formed an entirety.
