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 disclosure relates to a concrete cover anchor bolt device for a PC beam support, comprising: an anchor bolt; a first spherical nut threadedly connected to the first end of the anchor bolt; a spherical nut seat arranged at the first end of the anchor bolt, the The concave spherical surface of the spherical nut seat is closely matched with the raised spherical surface of the first spherical nut; the second spherical nut is threadedly connected to the second end of the anchor bolt; the spherical washer is arranged on the second end of the anchor bolt, and the spherical washer The convex spherical surface closely matches the concave spherical surface of the second spherical nut; the lock nut is threadedly connected to the second end of the anchor bolt and is located on the side of the second spherical nut toward the second end; wherein the first spherical nut, the spherical The surfaces of the nut seat, the spherical washer, the plane washer, the second spherical nut and the locknut are treated with a nitriding process and an in-situ growth composite material process to form an infiltrated layer of anti-corrosion and wear-resistant materials. The disclosure can improve the anti-corrosion and wear-resisting properties of the concrete cover anchor bolts and prolong the service life.

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,...
