A sensor installation structure for building construction based on fiber grating

Abstract

The invention discloses a sensor installation structure used for building construction based on a fiber bragg grating. The structure comprises a first fixing block, a fiber bragg grating sensor body,a bolt and a cross rod. Two ends of the fiber bragg grating sensor body are provided with second fixing blocks. Second through holes are arranged in bottom ends of the two second fixing blocks. A screw hole is arranged in a front surface of the first fixing block. The bolt penetrates through the second through holes and is screwed into the screw hole. First through holes are arranged in the top ends of the two second fixing blocks. One end of the cross rod penetrates through the first through hole, and a thread is arranged at one end of the cross rod. One end of the cross rod matches with thefirst through hole, two nuts installed at one end of the cross rod in a screw installation mode are attached to two sides of the top ends of the second fixing blocks. A hanging ring is fixed to a bottom end of the cross rod, and the two ends of the fiber bragg grating sensor body are connected with wires. In the invention, the sensor and the wires can be conveniently fixed and time is saved.

Description

technical field [0001] The invention relates to the technical field of installation of optical fiber grating sensors, in particular to a sensor installation structure for building construction based on optical fiber gratings. Background technique [0002] Fiber Bragg grating sensor is a kind of fiber optic sensor. The sensing process based on fiber Bragg grating is to obtain sensing information through the modulation of fiber Bragg wavelength by external physical parameters. It is a wavelength modulation fiber optic sensor. direct measurement. [0003] Reinforcement and underpinning in the reconstruction of existing building structures first reinforce the existing load-bearing structure and then perform underpinning processing. When renovating the existing building structure, it is necessary to monitor the relevant data of the load-bearing system of the building, which can be carried out through fiber optic grating sensors. monitor. [0004] The existing fiber grating sens...
