Embodiment Construction

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] Please also refer to figure 1 and figure 2 , the steel box girder oblique web fatigue test device provided by the present invention is now described. The steel box girder fatigue test device includes two sets of support assemblies and loading assemblies. The support assemblies are arranged at both ends of the oblique web 1. The web 1 plays a supporting role and keeps the inclined web 1 in a vertical state, and the support assembly is filled with concrete 22 to realize reinforcement; the loading assembly is arranged above the upper wing 11 to load the upper...

Abstract

The invention provides a steel box beam inclined web plate fatigue testing device, and belongs to the technical field of engineering detection. The steel box beam inclined web plate fatigue testing device comprises two groups of supporting components and loading components, the supporting components are arranged at two ends of an inclined web plate for supporting the inclined web plate and maintaining the inclined web plate at a vertical state, and the supporting components is filled with concrete to achieve a reinforcement function; the loading components are arranged above an upper wing plate for loading a vertical acting force to the upper wing plate so as to provide a loading force for a fatigue test of the inclined web plate, and the loading force is a component force of the loading force required in a full-scale test, so that the requirements for the loading equipment are reduced; and the loading force directly acts on the steel box beam inclined web plate, so that the obtained experimental result is more accurate than that in a scale test; and the steel box beam inclined web plate fatigue testing device provided by the invention is a novel testing device with lower requirements for loading equipment and less error.

Description

technical field [0001] The invention belongs to the technical field of engineering detection, and more specifically relates to a fatigue test device for inclined webs of steel box girders. Background technique [0002] With the rapid development of my country's economy and the further increase of investment in urban infrastructure, steel box girders are widely used in municipal bridge structures due to their superior performance. The steel box girder is generally connected by the top plate, bottom plate, web, transverse diaphragm, longitudinal diaphragm and stiffeners through full welding; among them, the web part is divided into straight web and oblique web according to the angle between the bottom plate and the bottom plate. Due to the advantages of slanted webs, such as aesthetic appearance, reduced floor materials and uniform stress, the use of slanted webs in bridge construction has long been a trend. [0003] Before the steel box girder is hoisted on site, the incline...
