Insertion plate type sling anchoring assembly of concrete-filled steel tubes arch bridge

Abstract

The invention discloses an insertion plate type sling anchoring assembly of a concrete-filled steel tubes arch bridge, and belongs to the technical field of sling connection. The insertion plate typesling anchoring assembly comprises a fixing base, a vibration reduction device is fixedly installed at the top of the fixing base, a connecting base is installed at the top of the vibration reductiondevice, a square groove is formed in the surface of the connecting base, a telescopic rod is installed on the inner side of the square groove, a limiting circular plate is installed at the top of thetelescopic rod, a connecting column is fixedly installed at the top of the limiting circular plate, a cylindrical magnetic block is fixedly installed at the top of the connecting column, a connectingsleeve is fixedly installed at the top of the connecting base, a metal column is movably arranged on an inner ring of the connecting sleeve in a sleeve mode, and a sling is fixedly installed at the top of the metal cylinder. According to the insertion plate type sling anchoring assembly, on the basis of the electro-magnetic principle, magnetic force of corresponding surfaces of the metal cylinderand the cylindrical magnetic block is attracted, dismounting and mounting are more convenient, the vibration reduction device plays a role in buffering on the rotation of the connecting base, and theinsertion plate type sling anchoring assembly has the characteristics of being stable in connection and high in safety.

Description

technical field [0001] The invention relates to the technical field of sling connection, in particular to a plate-type sling anchor assembly for a steel tube concrete arch bridge. Background technique [0002] Concrete-filled steel tube tied arch bridges are widely used in urban landscape bridges and highway bridges due to their advantages of large span, light structure, beautiful shape, and low building materials. In order to ensure the safety of the sling, regular maintenance is required. However, the traditional sling anchor assembly uses the cooperation of bolts and connecting cylinders to fix the sling. Since the bolts are exposed to the air for a long time, they are easily corroded by air and rain. , lead to corrosion and cannot be disassembled, which brings great difficulties to maintenance, and the strength of the bolts may be reduced after corrosion, resulting in unstable connections and potential safety hazards. At the same time, when the sling is blown by the wind...

Problems solved by technology

In order to ensure the safety of the sling, regular maintenance is required. However, the traditional sling anchor assembly uses the cooperation of bolts and connecting cylinders to fix the sling. Since the bolts are exposed to the air for a long time, they are easily corroded by air and rain. , lead to corrosion and cannot be disassembled, which brings great difficulties to maintenance, and the strength of the bolts may be reduced after corrosion, resulting in unstable connections and potential safety hazards. At the same time, when the sling is blown by the wind, it will wrap around the anchor components Rotate, that is, generate thrust on the anchor components, and the rigid connection between the anchor components is prone to cracks under stress, endangering the safety of the bridge
