Description
Technical field
The present invention relates to pre-stressed carbon fiber plate technique field, specially a kind of detachable anchorage device for prestressing force carbon plate tensioning..
Background technology
Pre-stressed carbon fiber plate technique is a new Reinforcement technology.Compared with traditional sticking carbon fiber plate technique reinforcement technique, this technology can make carbon fiber board just be in higher stress level before the load stress of structure transmission is undertaken, and certain intensity be played in advance, so as to realize making full use of for its high-strength performance.
Carbon fiber sheet is one of best material of decay resistance in current construction material.Shown according to data：Mechanical property and ageing-resistant performance influence of the environmental activities such as weak acid, weak base, Frozen-thawed cycled, long-time sunshine on carbon fiber is minimum.Conventional Carbon Fiber Sheet-Reinforced technology, is, in structure tensile zone chemical adhesive sticking carbon fiber sheet material, it is born tension jointly with concrete members and internal reinforcing bar at present.But this reinforcement process is extremely low to the utilization rate of carbon fiber strength, because the modulus of elasticity of carbon fiber sheet is 170GPa, tensile strength is up to 2800MPa, and to play tensile strength needs 1.7% stretcher strain;And the modulus of elasticity of reinforcing bar is generally 200GPa, tensile strength is only 300MP or so, and to play tensile strength needs 0.15% stretcher strain.When carbon fiber sheet and component inside reinforcing bar cooperation, the original initial strain of reinforcing bar is not considered, the intensity that carbon fiber sheet can be played during reinforcement yielding be also only the 8.8% of tensile strength and under 1.7% strain required for allowing carbon fiber to play whole intensity, concrete structure can produce big deformation and obvious crack, and the stripping damage at carbon fiber plate two ends also limit the performance of effect in addition.
Major part producer fixes anchor head two ends by the way of a kind of adhesive pastes carbon plate at present, and then applying pulling force makes carbon plate stress.So as to reach the application effect of prestressed stretch-draw.If causing tensioning failure, it is necessary to re-paste, shortcoming is as follows：Re-pasting needs the waste of big content of starting materials, and labor hour；Need the curing cycle of 48 hours；Repeatability is pasted substantially cannot；Carbon plate length must be determined according to job site（Without variability）.
The content of the invention
It is an object of the invention to provide a kind of detachable anchorage device for prestressing force carbon plate tensioning, to solve the problems mentioned in the above background technology.
To achieve the above object, the present invention provides following technical scheme：A kind of detachable anchorage device for prestressing force carbon plate tensioning, including detachable anchor head, carbon fiber board and oil cylinder mounting groove, the two ends of the carbon fiber board are separately installed with fixing end slideway and stretching end slideway, the detachable anchor head is flexibly connected by carbon fiber board with fixing end slideway and stretching end slideway, oil cylinder has been surrounded by the oil cylinder mounting groove, the end of the oil cylinder is provided with jackscrew, the jackscrew is flexibly connected with detachable anchor head, the bottom of the oil cylinder is provided with fixed end clamp plate, and the fixed end clamp plate is flexibly connected with carbon fiber board.
Compared with prior art, the beneficial effects of the invention are as follows：This is used for the detachable anchorage device of prestressing force carbon plate tensioning, detachable anchor head, it can only be slided between fixing end slideway and stretching end slideway, the detachable anchor head of oil cylinder pushing is slided, when reaching construction pulling force, stop, and fix position with jackscrew, spy uses the principle of 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 only relevant with the material of press strip, carbon fiber board can not only provide detachable installation, repeatable tensioning can be realized repeatedly simultaneously, greatly solve the waste of artificial and former material, curing time is not needed, it is easy to construction, accident risk is installed in reduction, normalizing operation and can arbitrarily it customize.
