This a can dismantle ground tackle for stretch -draw of prestressing force carbon plate, the size of the direct steerable prestressing force stretch -draw of fixing bolt of anchor head can be dismantled to special the biggest quiet friction force's the principle that adopts, and carbon fiber plate not only can provide demountable installation, can realize repeatability stretch -draw many times simultaneously, but reduces installation accident risk normalizing operation and random customization.
Description
Technical field
This utility model relates to pre-stressed carbon fiber plate technique field, a kind of detachable anchorage device for prestressing force carbon plate stretch-draw.
Background technology
Pre-stressed carbon fiber plate technique is a novel Reinforcement technology.Compared with traditional sticking carbon fiber plate technique reinforcement technique, this technology can make carbon fiber board just already at higher stress level before undertaking the load stress of structure transmission, plays certain intensity in advance, thus realizes making full use of of its high-strength performance.
Carbon fiber sheet is one of material that in current construction material, decay resistance is best.Show according to data: the environmental activities such as weak acid, weak base, freeze-thaw cycle, long-time sunshine are minimum on mechanical property and the ageing-resistant performance impact of carbon fiber.The most conventional Carbon Fiber Sheet-Reinforced technology, is at structure tensile zone chemical adhesive sticking carbon fiber sheet material so that it is jointly bear tension with concrete members and internal reinforcing bar.But this reinforcement process is extremely low to the utilization rate of carbon fiber strength, because the elastic modelling quantity of carbon fiber sheet is 170GPa, tensile strength is up to 2800MPa, and tensile strength to be played needs the stretcher strain of 1.7%;And the elastic modelling quantity of reinforcing bar is generally 200GPa, tensile strength is only about 300MP, and tensile strength to be played needs the stretcher strain of 0.15%.When carbon fiber sheet and component inside reinforcing bar cooperation, do not consider the original initial strain of reinforcing bar, the intensity that during reinforcement yielding, carbon fiber sheet can play be also only the 8.8% of tensile strength and under allowing carbon fiber play the strain of 1.7% required for whole intensity, xoncrete structure can produce big deformation and obvious crack, and additionally the stripping damage at carbon fiber plate two ends also limit the performance of effect.
The mode that major part producer uses a kind of adhesive to paste carbon plate at present makes anchor head two ends fix, and then applies pulling force and makes carbon plate stress.Thus reach the application effect of prestressed stretch-draw.If causing stretch-draw failure, needing to re-paste, shortcoming is as follows: re-paste the waste needing big content of starting materials, and labor hour；Need the curing cycle of 48 hours；Repeatable stickup substantially cannot；Carbon plate length must determine (without variability) according to job site.
Summary of the invention
The purpose of this utility model is to provide a kind of detachable anchorage device for prestressing force carbon plate stretch-draw, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of detachable anchorage device for prestressing force carbon plate stretch-draw, including detachable anchor head, carbon fiber board and oil cylinder mounting groove, the two ends of described carbon fiber board are separately installed with fixing end slideway and stretching end slideway, described detachable anchor head is flexibly connected with fixing end slideway and stretching end slideway by carbon fiber board, it has been surrounded by oil cylinder in described oil cylinder mounting groove, the end of described oil cylinder is provided with jackscrew, described jackscrew is flexibly connected with detachable anchor head, the bottom of described oil cylinder is provided with fixing end clamp plate, described fixing end clamp plate is flexibly connected with carbon fiber board.
Compared with prior art, the beneficial effects of the utility model are: this is for the detachable anchorage device of prestressing force carbon plate stretch-draw, detachable anchor head, can only slide between fixing end slideway and stretching end slideway, the detachable anchor head of oil cylinder pushing slides, when reaching construction pulling force, stop, and fix position with jackscrew, the special principle using maximum quiet frictional force, the fixing bolt of detachable anchor head directly can control the size of prestressed stretch-draw, and the size of maximum quiet frictional force is the most relevant with the material of press strip, carbon fiber board is possible not only to provide detachable installation, repeatable stretch-draw can be realized repeatedly simultaneously, greatly solve the waste of artificial and former material, need not curing time, it is easy to construction, reduce and accident risk is installed, can normalizing operation and can arbitrarily customizing.
