Problems solved by technology

Due to the special working environment, such as in the atmospheric environment, rain erosion, impact wear caused by vehicle operation, etc., the concrete cover anchor bolt assembly on the PC track beam support is extremely easy to corrode, has poor wear resistance, and is not impact resistant. Defects, in addition, there are phenomena such as occlusal bonding in the threaded bolt pair, these factors lead to a short service life of the concrete cover anchor bolt assembly, and indirectly affect driving safety

Abstract

The invention discloses an anchoring bolt device of a concrete cover for a PC beam support, which comprises an anchoring bolt; a first spherical nut is in threaded connection with the first end of theanchoring bolt; a spherical nut seat is arranged at the first end of the anchoring bolt, and the concave spherical surface of the spherical nut seat is closely matched with the convex spherical surface of the first spherical nut; a second spherical nut is in threaded connection with the second end of the anchoring bolt; a spherical washer is arranged at the second end of the anchoring bolt, and the convex spherical surface of the spherical washer is closely matched with the concave spherical surface of the second spherical nut; a locking nut is in threaded connection with the second end of the anchoring bolt and is positioned at one side of the second spherical nut facing the second end direction; the surfaces of the first spherical nut, the spherical nut seat, the spherical washer, a plane washer, the second spherical nut and the locking nut are treated by a nitriding process and an in-situ growth composite material process to form an anti-corrosion wear-resistant material infiltration layer. According to the anchoring bolt device, the corrosion resistance and wear resistance of the anchoring bolt of the concrete cover can be improved, and the service life can be prolonged.

Description

technical field [0001] The disclosure relates to the technical field of rail transit components, in particular to a concrete cover anchor bolt device for a PC beam support. Background technique [0002] The PC beam support is an important part of the PC track beam of straddle rail transit. Its main function is to transmit the force and displacement of the upper structure of the track beam to the lower structure, so as to meet the needs of the bridge span structure for force and displacement. An important connection part of the PC beam support is the concrete cover anchor bolt assembly, which is used for the fastening connection between the PC beam support and the bridge pier. Due to the special working environment, such as in the atmospheric environment, rain erosion, impact wear caused by vehicle operation, etc., the concrete cover anchor bolt assembly on the PC track beam support is extremely easy to corrode, has poor wear resistance, and is not impact resistant. Defects,...
