Embodiment Construction

[0037] The present invention will be further described below in conjunction with accompanying drawing:

[0038] Such as image 3 As shown in , it is a schematic structural diagram of a replaceable anti-fatigue orthotropic plate structure.

[0039] The detachable anti-fatigue orthotropic plate structure of the present invention includes several U-rib assemblies 100 detachably arranged. The U-rib assemblies 100 include U-shaped ribs 101, and the two sides of the U-shaped ribs 101 are inclined edges. The upper end of the U-shaped rib 101 is fixedly connected to the top plate 400 by non-welding. Preferably, the connection manner between the U-shaped rib 101 and the top plate 400 includes bolt connection or riveting.

[0040] On the outer sides of both sides of the U-shaped rib 101, a receiving plate 102 is affixed, and the receiving plate 102 abuts against the oblique lateral limiting assembly 200. The connecting plate 201 is vertically provided with a limiting plate 202 on the...

Abstract

The invention discloses a replaceable anti-fatigue orthotropic plate structure and a replacement method. The replaceable anti-fatigue orthotropic plate structure includes several U-rib assemblies detachably arranged. The U-rib assemblies include U-shaped ribs, U-shaped The upper end of the rib and the top plate are fixedly connected by non-welding; the replacement method includes that when a structural abnormality is detected in a specific U-rib assembly, the connection between the connecting plate and the diaphragm corresponding to the target assembly is sequentially disassembled. The invention achieves the purpose of avoiding fatigue damage by releasing the stress concentration between the U rib and the steel roof and the U rib and the diaphragm; at the same time, through the standardization and modularization of the U rib assembly, the oblique lateral limit assembly, and the vertical limit piece The mechanical and detachable connection between them realizes the replacement of damaged components, and solves the problem that traditional steel orthotropic plates are prone to fatigue cracking and difficult to repair.

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...
