Overhead load steel structure deformation real-time detection apparatus and detection method thereof

Abstract

The invention discloses an overhead load steel structure deformation real-time detection apparatus and a detection method thereof. The detection apparatus comprises two fixation rings, a fixation frame and two baffle plates. The fixation rings are respectively arranged at the reverse surfaces of two ends of the stress surface of a steel structure, the axes of the two metal rings are parallel to the steel structure, and the end surfaces of the metal rings are vertical to the axes; the fixation frame is arranged at any one end of the two metal rings and is coaxial with the two meal rings; and the two baffle plates are arranged at positions where the intermediate portion of the steel structure is most likely to be deformed, the thickness of the baffle plates is the same as that of the metal rings, the baffle plates are parallel to the end surfaces of the metal rings in terms of positions, and inner-side distance between the two baffle plates is equal to the internal diameter of the metal rings, and the two baffle plats are disposed right in the middle. The detection method comprises detachably fixing a ray apparatus on the fixation frame and arranging a portable deep-color light shielding cardboard so that a deformation state can be determined from a projection shape on the cardboard. According to the invention, state maintenance correction and real-time tracking of overhead load steel structure deformation bending measurement can be realized, and accidents caused by an overlarge steel structure deformation amount under the condition of uncertain load influences can be prevented.

Description

Technical field [0001] The invention relates to a method for detecting deformation of a steel structure, in particular to a method for detecting deformation of a steel structure that is fixed overhead and subjected to reciprocating force. Background technique [0002] The deformation and bending measurement of long-distance overhead steel structures, especially the measurement of micro deformation, is a difficult problem in the industry. As the structure of the frame subjected to the balance force, there will generally be a relatively solid civil construction or bracing foundation, and the deformation of the frame is generally not large; as the frame subjected to the reciprocating dynamic force, the force process is affected by many factors, such as Vibration, eccentric load, etc., under the influence of such factors, the probability of elastic or plastic deformation of steel structures is greatly increased. Especially for some rail-loaded steel structures, the load is unbalance...

AI Technical Summary

Problems solved by technology

[0004] The implementation of the existing technology requires the cooperation of multiple people at both ends, such as pulling wires at both ends, and judging the curvature of the edge of the steel structure with the straightened line as a reference. When judging the curvature of the suspended part of the steel structure, it is necessary to set up a scaffolding close to the visual inspection , and every operation needs to be like this, the input of manpower and material resources is relatively large and cumbersome
