Description

Technical Field

[0001] The utility model belongs to the technical field of building detection, in particular to a building deformation measuring device. Background Art

[0002] Building has two meanings, broad and narrow. In the broad sense, building refers to everything artificially built, including both houses and structures. In the narrow sense, building refers to houses, excluding structures. Houses are spaces with foundations, walls, roofs, doors, and windows that can shelter people from wind and rain, and are used for living, working, studying, entertainment, storage, or other activities.

[0003] As a type of building, cylindrical buildings require measuring devices to determine whether they are safe during construction and later use, thereby protecting the lives and property of users.

[0004] A utility model patent application with announcement number CN215448031U discloses an intelligent building anti-deformation safety monitoring device, which relates to the field of building detection technology. The utility model includes a frame, on which a tilt component, a settlement component, a crack component, and a deflection and horizontal displacement component are installed. The settlement component is located in the middle of the frame. The utility model is an intelligent building anti-deformation safety monitoring device. The counterweight drives the pointer to rotate, and cooperates with an angle scale to measure whether the building is tilted. The sleeve rod is fixed to the ground through a first connecting rod and a mounting bar. The telescopic rod is connected to the wall or foundation through the frame. It is suitable for detecting whether the building wall or foundation has settled. The presence of a crack between the laser rangefinder and the positioning block is determined by whether the distance between the laser rangefinder and the positioning block has changed. The deflection and horizontal displacement component directly measures the deflection and horizontal displacement of the building through a deflection meter. It has diversified functions and is more intelligent.
