The present invention relates to the technical field of temperature and humidity monitoring of concrete, and discloses a distributed optical fiber concrete temperature monitoring structure based on acarbon fiber pull screw. The structure comprises a detection area, a distributed optical fiber and a data collector. The distributed optical fiber is installed in a detection area. The distributed optical fiber is electrically connected with the data collector through a signal transmission line, and the distributed optical fiber transmits the detected information to the data collector through thesignal transmission line. The pull screw comprises a rod which is located in the detection area. The distributed optical fiber is mounted on the rod in a stripped shape, and the two ends of the rod respectively extend along the length direction of the rod. The rod is hollow inside. The signal transmission line connected with the distributed optical fiber is exactly arranged inside the rod and extends out of the detection area through the rod to be connected with the data collector so that the temperature and humidity collection of the concrete can be realized.
Description
technical field [0001] The invention relates to the technical field of concrete temperature and humidity monitoring, in particular to a distributed optical fiber concrete temperature monitoring structure based on carbon fiber parallel pull screws. Background technique [0002] In the construction process of building structures, especially in the process of pouring large-volume concrete load-bearing walls, the pull screw is an indispensable device. Afterwards, the concrete is poured to form the walls. [0003] At present, the concrete walls in construction engineering will form various cracks due to various reasons after the pouring is completed. Studies have shown that the hydration heat reaction inside the concrete during the pouring process is an important factor for the formation of non-load cracks (cracks not caused by force). Therefore, monitoring the temperature and humidity of concrete walls in important parts is one of the effective means to find out the cracking of...
