Stress rapid detection system of multi-arc steel member and natural vibration method thereof

Abstract

The invention discloses a multi-arc steel member stress rapid detection system and a natural vibration method thereof, the system comprises a containing box, a placing frame and a containing chamber, the placing frame is fixedly arranged at the top of the containing box, the containing chamber is fixedly arranged at the top of the placing frame, and a plurality of first motors are uniformly and fixedly arranged at the bottom of an inner cavity of the containing box; the invention relates to the technical field of engineering mechanics. According to the stress rapid detection system of the multi-arc-shaped steel member and the natural vibration method thereof, through mutual cooperation of the functional rod assembly, the first spring and the contact strip block assembly, the bottoms of different multi-arc-shaped steel members can be limited, limiting and clamping can be achieved in combination with the first hydraulic rod, the second hydraulic rod and the jacking pressing strip, the application range is wide, and the practicability is high. And through mutual cooperation of the anti-inclination rod and the counterweight ball, the contact strip mechanism always keeps moving in the vertical direction and does not incline, it is guaranteed that the first contact block and the second contact block can make contact in time, and operation is sensitive.

Description

technical field [0001] The invention relates to the technical field of engineering mechanics, in particular to a stress rapid detection system for multi-arc steel components and a self-vibration method thereof. Background technique [0002] Steel members refer to steel structural composite members that can bear and transmit loads and are connected by steel plates, angle steels, channel steels, I-beams, welded or hot-rolled H-beams, cold-bent or welded through connectors. The steel component system has comprehensive advantages such as light weight, factory manufacturing, fast installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution. Compared with reinforced concrete structures, it is more "high, large, and light" With the unique advantages of development in three aspects, steel components have been reasonably and widely used in the field of construction engineering worldwide, especially in developed countrie...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a stress rapid detection system for multi-arc steel members and its self-vibration method, which solves the problem that only single-arc steel members can be limited and clamped, and the scope of use is limited. Due to the limitations, it cannot be adapted to a variety of multi-curved steel structures, resulting in instability in the detection of other steel components, and large errors in the final data of the detection, lack of fast and stable clamping of different multi-curved steel structures solid structure problem
