Description
Technical field
The utility model relates to a kind of fiber reinforced plastic rod or drag-line bond type anchorage fatigue experimental device.
Background technology
Fibre reinforced composites FRP (Fiber Reinforced Polymer/Plastic) muscle or drag-line are active day by day in Application in Civil Engineering research; Also extensive day by day in actual application in engineering; But because FRP muscle or drag-line are a kind of transverse isotropy materials; Its shearing strength and tension are lower to intensity, and the greatest difficulty that makes FRP muscle or drag-line in application, run into is exactly its anchoring problem.Though existing at present high performance concrete has static(al) anchoring property preferably as the FRP muscle or the drag-line bond type anchorage of cementing medium, its fatigue behaviour under Fatigue Load is worth researcher's discussion.When fiber reinforced plastic rod or drag-line are carried out torture test, should merit attention and touch head under the control of fatigue tester during the moving crossbeam application of force, moving crossbeam is because of discontinuity, and it is moving to swing sideward, and causes test result inaccurate.
Summary of the invention
The purpose of the utility model is, to the deficiency of prior art, a kind of fiber reinforced plastic rod or drag-line bond type anchorage fatigue experimental device is provided, and can prevent that the stop crossbeam swings sideward movingly, makes that to measure accuracy high.
The technical scheme of the utility model is; A kind of fiber reinforced plastic rod or drag-line bond type anchorage fatigue experimental device comprise two parallel columns, are fixed with supporting traverse on the top of two columns; The upper end of fatigue tester is fixed on the supporting traverse; The lower end of this fatigue tester links to each other with the shake-up head through touching axle, it is characterized in that, touches the head below and is provided with moving crossbeam; Moving crossbeam two ends place respectively on the bond type anchorage of corresponding fiber reinforced plastic rod or the connection of drag-line lower end; Said fiber reinforced plastic rod or drag-line upper end are fixed on the supporting traverse through strand tapered anchorage, and the front-axle beam of said moving crossbeam and back rest both sides are respectively equipped with relative limiting plate, and the two ends of each limiting plate are separately fixed on the corresponding column.
Below the utility model is further described.
Said column is that the cross section is " worker " font.
The front-axle beam of said moving crossbeam and the back rest respectively are provided with threaded hole, and corresponding limiting plate is provided with the threaded hole corresponding with threaded hole, and said moving crossbeam is connected with limiting plate through the bolt that passes said threaded hole during non-test.
The two ends of said moving crossbeam are respectively equipped with the groove that can supply fiber reinforced plastic rod or drag-line to pass.
Every fiber reinforced plastic rod or drag-line are provided with pressure transducer between bond type anchorage and moving crossbeam.
Install limiting plate additional in moving crossbeam both sides, can prevent effectively that the stop crossbeam swings sideward moving; Moving crossbeam is provided with threaded hole in the direction perpendicular to limiting plate, the relevant position of a limiting plate be provided with limiting plate on the corresponding threaded hole of threaded hole, can will move crossbeam when not working and be connected installing with limiting plate, anti-locking apparatus sustains damage.
Known that by above the utility model is a kind of fiber reinforced plastic rod or drag-line bond type anchorage fatigue experimental device, moving crossbeam is swung sideward movingly in the time of can effectively preventing to measure, and improves the accuracy of measuring.
