Abstract

The problem to be solved by the invention is how to make a crack monitor have a bending deformation monitoring function. The crack deformation monitor includes two vertical columns, a measuring rod, atelescopic displacement sensor(s) A, an angle sensor A, an angle sensor(s) B, and a data monitoring end. The two vertical columns are fixedly installed on structures on both sides of a crack. The twovertical columns are perpendicular to planes of the respective structures. Both ends of the measuring rod are cylinders. Generatrix directions of the cylinders are at an angle with the measuring rod.The inside diameter of the cylinders is equal to the outside diameter of the vertical columns. The two vertical columns are sleeved with the two cylinders. The measuring rod has a telescopic structure on one side or both sides and the telescopic displacement sensor A is installed at each telescopic structure. A single axis rotation structure is at the middle of the measuring rod, and the angle sensor A is installed at the single axis rotation structure. The angle sensor B is installed at the vertical column and cylinder on one side or the angle sensors B are installed at the vertical columnsand cylinders on both sides. Data measured by all the sensors are transmitted to the data monitoring end by a wireless or wired manner. The monitoring functions are organically integrated through themeasuring rod, and the crack deformation monitor is comprehensive and accurate.

Description

technical field [0001] The invention relates to the field of measurement technology, especially the monitoring of structures, buildings or ground cracks. Background technique [0002] At present, the fracture monitor can measure data such as fracture width, translation and dislocation on both sides of the fracture, but it has not been seen to have the function of measuring fracture bending deformation. [0003] The so-called bending deformation means that the two sides of the crack rotate along the axis of the crack, so that the planes where the two sides are located are no longer parallel. When the crack is squeezed face-to-face, it is easy to bend and deform. For example, when the bridge is impacted by a huge water flow, bending may occur at the impact. This deformation poses a great threat to the structural stability on both sides of the crack. [0004] Bending deformation does not appear in the relative translation of the two sides of the crack on the plane, nor does i...
