Replaceable anti-fatigue orthotropic plate structure and replacement method

Abstract

The invention discloses a replaceable anti-fatigue orthotropic plate structure and a replacement method. The replaceable anti-fatigue orthotropic plate structure comprises a plurality of U-shaped ribassemblies which are detachably arranged, each U-shaped rib assembly comprises a U-shaped rib, and the upper end of each U-shaped rib is fixedly connected with a top plate in a non-welding mode; the replacement method comprises the step that when it is detected that the structure of the specific U-rib assembly is abnormal, the connecting pieces of the connecting plate and the transverse partitionplate corresponding to the target assembly are sequentially detached. The purpose of avoiding fatigue damage can be achieved by releasing stress concentration of the U-shaped ribs and the steel top plate and stress concentration of the U-shaped ribs and the transverse partition plates; meanwhile, through standardization and modularization of the U-shaped rib assemblies, oblique lateral limiting assemblies and vertical limiting pieces and mechanical and detachable connection between the U-shaped rib assemblies, the oblique lateral limiting assemblies and the vertical limiting pieces, damaged components can be replaced, and the problems that a traditional steel orthotropic plate is prone to fatigue cracking and not easy to repair are solved.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a replaceable anti-fatigue orthotropic plate structure and a replacement method. Background technique [0002] The steel orthotropic plate is a load-bearing structure composed of vertical and horizontal stiffeners (or diaphragms) and a steel roof. The self-weight of the steel orthotropic slab is about 1 / 4 to 1 / 5 of the self-weight of the reinforced concrete bridge deck or the prefabricated prestressed concrete bridge deck, and its transportation and erection are convenient and the construction period is short. [0003] It was proposed in the 1930s, and the technology was applied to build the Kurpfalz Bridge in 1950. This bridge is the first in the world to use the steel orthotropic plate structure as a part of the main girder to participate in the joint force, and at the same time as the bridge deck Steel structure bridges bearing local traffic loads have been widely u...
