Description
Technical field
The utility model belongs to field of civil engineering, is specifically related to a kind of prestressing carbon fiber plastic plate anchor system.
Background technology
Fibre reinforced plastics (Fiber Reinforced Plastics) are called for short FRP, be applied to up to now in the fiber-like material field of civil engineering the earliest, technology is the most ripe, consumption is maximum a kind of high-tech material.According to the difference of kinds of fibers, the FRP material can be divided three classes: CFRP (carbon fiber plastic), GFRP (fiberglass plastic), AFRP (aramid fiber plastics).Wherein not only tensile strength and modulus of elasticity are the highest for CFRP, and acid and alkali resistance, salt, drying and watering cycle and other chemical solvent and more the ability of difference ring border condition also obviously be better than GFRP and AFRP.According to different product forms, FRP can be divided into: FRP section bar, FRP sheet material (cloth material and sheet material) and FRP bar etc.
The CFRP plate is pasted on the tension face of concrete beam, can effectively improves the anti-bending bearing capacity and the rigidity of beam, the control crack width.Than traditional reinforcement means, the advantage of CFRP plate reinforcing method has: 1. intensity height, and CFRP plate tensile strength can reach 3000MPa, and consolidation effect is good; 2. volume and deadweight are little, increase the size and the weight of structure hardly; 3. there is not unnecessary welding node; 4. durability and corrosion resistance are good; 5. easy construction.
But CFRP plate reinforcing method also exists deficiency, and correlation test is the result show: when common CFRP plate reinforcement took place to destroy, the tensile stress of CFRP plate only was 10%～20% of its tensile strength, and the high strength of CFRP plate is not in full use.
After the CFRP plate applied prestressing force, the CFRP plate had just been brought into play suitable intensity before joist support is subjected to load, so not only can make full use of the high strength of CFRP plate, improve the stress and the performance of beam, effectively improve the cracking load and the yield load of beam, can also further suppress the distortion of beam and the development in crack.
Because CFRP plate shear strength is very low, realize the stretch-draw to the CFRP plate, need special ground tackle, domestic research to the Prestressed CFRP beaverboard anchorage at present still is blank.
The utility model content
The technical problems to be solved in the utility model is to develop a kind of anchor system that can carry out stretch-draw and anchoring to the prestressing carbon fiber plastic plate.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of prestressing carbon fiber plastic plate anchor system, comprise anchored end and stretch-draw end two parts, described anchored end and stretch-draw end respectively are provided with a clamping device, this clamping device comprise lower plate and between the last lower plate lower bolster, connect with a plurality of securing members between the last lower plate.
The stretch-draw end of this anchor system also is provided with a connector, one end of connector is connected by pin with the clamping device of stretch-draw end, the other end is provided with screw, is connected with pull bar by screw thread, utilizes common hydraulic jack can realize stretch-draw and anchoring to the carbon fiber plastic plate.
Anchor system of the present utility model is simple and reasonable, and is workable, and Practical Performance is good, and with low cost.
