Monofilament anchoring test device and detection method thereof

Abstract

The invention relates to a monofilament anchoring test device and a detection method thereof, and belongs to the technical field of mechanical equipment. The device comprises a monofilament anchor cup, a through hole is formed in the center of the monofilament anchor cup, and a connecting sleeve is arranged at one end of the monofilament anchor cup and is in threaded connection with the monofilament anchor cup; a sealing cover plate is arranged at the other end of the monofilament anchor cup, a boss is arranged in the center of the sealing cover plate, and the boss is arranged in the through hole, so that the sealing cover plate covers the other end of the monofilament anchor cup; a wire penetrating hole is formed in the center of the sealing cover plate and penetrates through the boss, sothe wire penetrating hole is communicated with the through hole, the center line of the wire penetrating hole and the center line of the through hole are located on the same straight line, and a steel wire penetrates into the center of the through hole through the wire penetrating hole. The steel wire penetrates into the monofilament anchor cup through the wire penetrating hole, it is guaranteedthat the steel wire and the monofilament anchor cup are coaxial, and the accuracy of a test value is improved. The strength and the pull-out amount of the steel wire are detected, and the casting compactness of the zinc-copper alloy is also detected.

Description

technical field [0001] The invention relates to a monofilament anchoring test device and a detection method thereof, belonging to the technical field of mechanical equipment. Background technique [0002] The strand anchor system of the main cable of a suspension bridge is the main link to realize the connection between the main cable strand and the anchorage, and is the core component for transferring load. The anchorage system of the cable strands of the suspension bridge is to install the anchorage with a cone cavity inside on the strands, and then cast the anchoring material to realize the connection between the strands and the anchorage. Zinc-copper alloy is generally used for the casting of the main cable strands and anchors of suspension bridges. The anchoring method is to clean the surface of the steel wire, melt the zinc-copper alloy and cast it in the anchor cup. The zinc-copper alloy and the steel wire form a cone to transmit the load. For ultra-high-strength mai...

Problems solved by technology

This method is easy to cause the steel wire to tilt inside the steel pipe, that is, it is difficult to ensure the coaxiality of the steel wire and the steel pipe, so that the anchoring part of the steel wire is not parallel to the force of the pull-out testing machine, resulting in a large error in the test value
