Abstract

The invention discloses a tensioning anchoring testing device and a tensioning anchoring testing method for a pre-stress carbon fiber plate reinforced steel beam. The device comprises an anchoring clamp and a tensioning device, wherein the anchoring clamp comprises an upper clamp plate and a lower clamp plate; a limiting outer frame plate is fixedly arranged on a tensioning anchoring beam of the tensioning device; a CFRP (Carbon Fiber Reinforced Plastic) plate through hole is formed in a front end plate of the limiting outer frame plate; groove tracks are formed in inner side surfaces of the left side plate and the right side plate of the limiting outer frame plate; tensioning clamps are arranged inside the groove tracks in a sliding manner; a mounting through hole is formed in a rear endplate of the limiting outer frame plate; a pre-stress bolt is mounted inside the mounting sliding hole in the sliding manner; the pre-stress bolt extends into one end of the limiting outer frame plateand is fixedly connected with the tensioning clamp; an anchoring plate is arranged at the other end of the limiting outer frame plate; a jack is arranged between the anchoring plate and the rear endplate of the limiting outer frame plate. By adopting the tensioning anchoring device and the tensioning anchoring testing method disclosed by the invention, the integrality of an original steel structure is not damaged, the holding capacity of the original steel structure is not reduced, the operation is convenient to carry out, the cost can be reduced, and the efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of prestressed tension anchorage, in particular to a tension anchorage experimental device and method for steel beams reinforced with prestressed carbon fiber plates. Background technique [0002] Carbon Fiber Reinforced Polymer (CFRP) is a new type of reinforcement material. Compared with traditional reinforcement materials such as steel, it has the advantages of high tensile strength, convenient construction, light weight, corrosion resistance and durability. With the continuous maturity of prestressing technology, the use of prestressed CFRP slabs to strengthen existing concrete structures has been widely used, but the reinforcement and repair of steel beam structures is still in the research stage. There are many technical difficulties in applying the existing prestressed tensioning and anchoring methods to CFRP reinforced steel beams. For example, the existing anchoring and tensioning devices are genera...
