Prestressed carbon fiber plate anchor test device

Abstract

The invention discloses a prestressed carbon fiber plate anchor test device, which is characterized in that one end of a test table of a test table installing and clamping device is fixedly provided with a blocking body with a middle hole; a pressure sensor sleeves a position, behind the middle hole, of the blocking body; an anchor tool is arranged at the rear side of the pressure sensor; the other end of the test table is provided with a hydraulic cylinder; an anchor tool is fixed on a piston rod of the hydraulic cylinder; a displacement sensor is fixed on the anchor; a carbon fiber plate is connected between the two anchors tools; an oil inlet oil pipe of a static load hydraulic pump station is connected onto a static pressure oil inlet opening of the hydraulic cylinder; a return oil pipe of the static load hydraulic pump station is connected onto a static pressure oil return opening of the hydraulic cylinder; an oil pressure transfer opening of a fatigue load loading power source is connected to a hydraulic transfer opening of the hydraulic cylinder through an oil pressure transfer pipe; the displacement sensor and the pressure sensor are respectively connected with a data detection instrument through a signal wire; the output signal wires of the data detection instruments are connected into a computer analysis device. The test device provided by the invention solves the static loading tension and fatigue detection problems of a carbon fiber plate anchor tool; an important effect is achieved on the effective engineering reinforcement.

Description

technical field [0001] The invention relates to a prestressed carbon fiber plate anchor test device. Background technique [0002] The engineering structure will lead to aging with the increase of the service time, because of the change of the use function, the problem of the engineering quality and the natural disaster, etc., it is necessary to take reinforcement measures. Traditional reinforcement methods mainly include: enlarging section method, outsourcing steel reinforcement method, external bonded steel reinforcement method, prestressed reinforcement method, adding fulcrum reinforcement method, crack repair method and sprayed concrete reinforcement method, etc. Compared with the traditional reinforcement method, the carbon fiber composite reinforcement method has the advantages of high strength, convenient and efficient construction, excellent chemical corrosion resistance, and good applicability, so it has been widely used. Although carbon fiber composites have high ...
