Description

Technical Field

[0001] The present invention relates to a displacement and trajectory inspection device for a seismic isolation building that can reliably inspect the functions of the seismic isolation building.

Background Art

[0002] In countries and regions located in seismic zones, earthquakes are likely to occur frequently due to geological influences. Therefore, when constructing buildings in such regions, seismic isolation design is generally incorporated (hereinafter referred to as seismic isolation buildings), and it is necessary to mitigate the transmission of seismic energy and prevent damage and collapse of the seismic isolation buildings. Seismic isolation design mainly uses a base layer or a certain layer in the lower layer of a seismic isolation building as a seismic isolation layer, and installs a plurality of sets of seismic isolation structures below the seismic isolation layer. By using these seismic isolation structures, seismic energy is absorbed to achieve the purpose of seismic isolation.

[0003] However, in the situation of intense earthquakes or long-term absorption of seismic energy, the seismic isolation structure may still experience a decrease in functionality or failure, such as being unable to recover to its original position or suffering structural damage. To avoid the occurrence of such situations, building owners generally entrust experts and institutions such as structural engineers regularly, and these experts and institutions inspect whether repair or replacement of the seismic isolation structure is necessary based on experience. However, such methods lack objective basis and are likely to cause problems of trust between the building owner and the experts and institutions.

[0008] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It goes without saying that the present invention is not limited to the embodiments described below.

[0009] The seismic displacement and trajectory inspection device for base-isolated buildings according to the present invention includes at least one multi-axis sensor module 10, one or more motion trajectory sensor modules 20, and a quantitative analysis module 30. The multi-axis sensor module 10 is installed on a seismically isolated building and can detect and record the acceleration and angular changes of the X, Y, and Z axes of the seismically isolated building. The motion trajectory sensor module 20 is installed on a seismically isolated building and can detect and record the range and trajectory of the building's movement. The quantitative analysis module 30 is connected to the multi-axis sensor module 10 and the motion trajectory sensor module 20, respectively. Based on the acceleration and angular changes of the X, Y, and Z axes detected by the multi-axis sensor module 10 and the range and trajectory of movement detected by the motion trajectory sensor module 20, the quantifiable analysis of the absorbed dynamic energy of the seismically isolated building and its response to the forces it receives can be performed.

[0010] The multi-axis sensor module 10 is installed on the seismic isolation structure of the seismically isolated building or on the building itself. The motion trajectory sensor module 20 is installed on the seismic isolation structure or the building itself.

[0011] The multi-axis sensor module 10 includes at least a tri-axis accelerometer 11, which can detect acceleration and angular changes in the X, Y, and Z axes of the seismically isolated building. The multi-axis sensor module 10 includes at least a gyroscope 12, which can detect acceleration and angular changes in the X, Y, and Z axes of the seismically isolated building.

[0012] The motion trajectory sensor module 20 includes at least an optical sensor 21, which can detect the range and trajectory of movement of the seismically isolated building. The motion trajectory sensor module 20 includes at least a position encoder 22, which can detect the range and trajectory of movement of the seismically isolated building.

[0013] The quantitative analysis module 30 includes at least an abnormality determination unit 31, which can determine whether or not there is an abnormality in the seismically isolated building based on the absorbed kinetic energy analyzed by the quantitative analysis module 30 and the response to the applied force. The abnormality determination unit 31 determines that the abnormality is one of the following conditions in the seismically isolated building: failure to recover from displacement, inelastic displacement, or damage to the seismic isolation structure in the seismically isolated building.

[0014] During use, the multi-axis sensor module 10 and motion trajectory sensor module 20 are mainly installed on the seismically isolated building, and the quantitative analysis module 30 is connected to the multi-axis sensor module 10 and motion trajectory sensor module 20 respectively. The multi-axis sensor module 10 is used to detect and record the acceleration and angular changes of the X, Y, and Z axes of the seismically isolated building, and the motion trajectory sensor module 20 is used to detect and record the range and trajectory of the movement of the seismically isolated building. The quantitative analysis module 30 receives the detections from the multi-axis sensor module 10 and motion trajectory sensor module 20 and quantifies and analyzes the absorbed kinetic energy of the seismically isolated building and its response to the forces it receives. This allows the business owner or inspection agency of the seismically isolated building to quickly grasp the functional status of the building and achieve the objective of reliably inspecting the functionality of the seismically isolated building.

[0015] In a preferred embodiment of the present invention, the multi-axis sensor module 10 and the motion trajectory sensor module 20 are installed separately or together on the seismic isolation structure or the building body of the seismically isolated building (not shown), thereby accurately detecting the acceleration and angular change in each axial direction of the seismically isolated building, as well as the range and trajectory of the movement of the seismically isolated building.

[0016] In a preferred embodiment of the present invention, the multi-axis sensor module 10 includes at least a tri-axis accelerometer 11 and / or a gyroscope 12 (see Figure 1), and uses the tri-axis accelerometer 11 and / or the gyroscope 12 to accurately detect the acceleration and angular changes of the X, Y, and Z axes of the seismically isolated building.

[0017] In a preferred embodiment of the present invention, the motion trajectory sensor module 20 includes at least an optical sensor 21 and / or a position encoder 22 (see FIG. 1), and uses the optical sensor 21 and / or the position encoder 22 to accurately detect the range and trajectory of the movement of the seismic isolation building.

[0018] When the seismic isolation building encounters an earthquake or other external forces and shakes occur in the seismic isolation building, the multi-axis sensor module 10 accurately detects and records the acceleration and angular changes in each axial direction of the seismic isolation building, and the motion trajectory sensor module 20 accurately detects and records the range and trajectory of the movement of the seismic isolation building. At the same time, based on the detections of the multi-axis sensor module 10 and the motion trajectory sensor module 20, the quantitative analysis module 30 quantifies and analyzes the absorbed dynamic energy of the seismic isolation building and the reaction to the force received. Thereby, the owner or inspection agency of the seismic isolation building can quickly grasp the functional status of the seismic isolation building, and achieve the purpose of inspecting the function of the seismic isolation building.

[0019] In a preferred embodiment of the present invention, the user can further investigate and view the detection records of the multi-axis sensor module 10 and / or the motion trajectory sensor module 20, and based on these records as objective evidence, enhance the persuasiveness of the inspection.

[0020] In a preferred embodiment of the present invention, the quantitative analysis module 30 may further include an abnormality determination unit 31 (see FIG. 1), and based on the absorbed dynamic energy and the reaction to the force analyzed by the quantitative analysis module 30 using the abnormality determination unit 31, it is possible to determine the presence or absence of abnormalities in the seismic isolation building. Thereby, the owner or inspection agency of the seismic isolation building can directly grasp the functional status of the seismic isolation building.

[0021] In the best embodiment of the present invention, the abnormalities determined by the abnormality determination unit 31 may be situations such as unrecovered displacement, inelastic displacement in the seismic isolation building, and / or damage to the seismic isolation structure in the seismic isolation building.

[0022] When the abnormality determination unit 31 determines that the seismic isolation building conforms to any one or more of the foregoing situations based on the absorbed dynamic energy analyzed by the quantitative analysis module 30 and the reaction to the received force, the owner or inspection agency of the seismic isolation building can promptly determine the repair plan and (or) location required for the seismic isolation building through the situation determined by the abnormality determination unit 31.

[0023] The above is the description of the embodiments of the present invention, and the present invention cannot be limited by these. All changes and modifications that do not depart from the scope of the utility model registration claims are included within the scope of the rights of the present invention.
