Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a hidden retractable settlement observation device. Background Art

[0002] In recent decades, with the continuous development of science and technology and the acceleration of urbanization, the number of high-rise buildings under construction in various places has increased rapidly, and their heights have also increased. In order to ensure safety during construction and use, it is very necessary to observe the settlement and deformation of high-rise buildings.

[0003] At present, the settlement observation devices commonly used in buildings are mostly deep-buried, foldable and hidden, or externally connected and rotating. Problems with existing settlement devices: (1) The deep-buried settlement observation device is exposed to the surface of the building for a long time, which is easy to cause deformation and damage during use, thereby affecting the use of settlement observation in the later stage. (2) If there are foreign objects or rust at the folding node of the foldable and hidden settlement observation device, the folding angle will change, thereby affecting the accuracy of the settlement observation data. (3) The externally connected and rotating settlement device requires special care, which may easily cause the rod to be lost and unusable. For example, the patent application with publication number CN217078246U in the prior art includes a detection box, an installation component and a detection component, wherein the detection box is provided with a movable cavity inside, and the detection component includes a detection horizontal plate, which is arranged in the movable cavity and can be moved in the movable cavity, and the detection component is arranged inside the detection box. After use, it needs to be folded, transported and stored, which is easy to lose. Utility Model Content

[0013] The end of the settlement observation rod away from the building is cylindrical, and the diameter of the cylinder is larger than the diameter of the settlement observation rod body;

[0014] The end of the rod body of the settlement observation rod close to the gasket has a square protrusion, and the square protrusion matches the shape of the hidden position groove, the observation position groove and the groove inlet;

[0015] The settlement observation rod is engraved with an observation position groove indicator line;

[0016] The length of the settlement observation rod body matches the groove of the hollow section at the fixed end.

[0017] Furthermore, the diameter of the cylinder is 1.5 times the diameter of the body of the settlement observation rod.

[0018] Furthermore, the side length of the square protrusion is 1 mm.

[0019] The advantages of the utility model are:
