Title:
ファイバグレイティングとボルトとを同時に前置引張可能な感知ネジデバイス及びシステム
Document Type and Number:
Japanese Patent JP5876109
Kind Code:
B2
Abstract:
An apparatus includes a sensing screw capable of providing synchronous both pre-drawing of fiber Bragg grating and pre-tightening of bolt with induced characteristics to detect feedback control of large scale public engineering structures or precise equipments to facilitate fabrication of precise elements to achieve more precise control and record fabrication processes. Through the sensing screw apparatus a precision system structure can be formed to meet expectation of improved product quality and comprehensive recording of complete production process and physical characteristics at important points of the production process. The invention can provide instant onsite status and accumulate data or make parameter pre-action to avoid error accumulation, thereby improve production yield or safety of large scale structures.
