Three-dimensional relative displacement identification device of the building caused by the earthquake, etc.

摘要

(57) [summary] (modified with) [challenge] the three-dimensional relative displacement of the building caused by an earthquake or the like, it can easily be identified in another direction, while field records the amount of displacement and orientation as a vector, buildings safety as, it is possible to obtain the risk as well as effective Naru judgment materials of progression and the like. A wall Russia, floor leaves, the light-emitting device 1 which emits Hosomitsu to three-dimensional, such as a ceiling surface two, for example, is attached Check the verticality in an appropriate position of the wall and Russia, such as the front door entrance, its fine Pasted the projection seal 8, 9, 10 each on each side where the light is projected. Concentric circles this time are printed on each seal 24 And the center of the, by the combination of previously align the center and orientation of Hosomitsu, if the displacement on each side is generated, it becomes that the amount of displacement and direction is projected, and the identification of extremely simple Naru displacement It is made possible. In addition, should we mark the displacement projection points 17, 18 and 19 each time such as an earthquake occurrence can vector as a site record, valuable materials can be obtained conveniently.
