A demonstration device for shock absorption and isolation of a building structure model

Abstract

The invention provides a building structure model shock-absorbing and isolation demonstration device, comprising: a main body, a force plate, a support bar, a bottom bar, a pull piece and a simulation piece; the main body is a rectangular structure; the main body includes a top groove, and The bottom of the main body is equipped with a vibration motor; the top of the main body is provided with several top grooves, and the top groove is a "middle" shape structure, and the outside of the top groove is provided with pull grooves, and the inside of the top groove is provided with several circles. hole; the force plate is embedded and installed inside the top groove, and the guide rod at the bottom of the force plate is inserted into the round hole inside the top groove; the support rod is used to be installed inside the bottom bar, so that the device During the delay shock absorption, the support rod can be in contact with the bottom rod through the spring, so that the support rod can expand and contract inside the bottom rod, so that the main body can be fully affected by the vibration and move, thereby simulating the delay ground undulation.

Description

technical field [0001] The invention belongs to the technical field of model shock-absorbing demonstration, and more specifically relates to a building structure model shock-absorbing and isolating demonstration device. Background technique [0002] When students in the Department of Architecture are in class, they usually need to use the shock absorption demonstration device to teach students, so that students can see the shock absorption of the building structure model. [0003] For example, the application number: CN201410013500.9 relates to a building structure model shock-absorbing and isolation technology demonstrator, including a building structure model, a seat plate and an earthquake simulation motion table, and it is characterized in that: one side of the seat plate is fixed to the building structure model connected, the other side is fixedly connected with the earthquake simulation motion table, and the two sides of the connection between the upper seat plate and ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a building structure model shock-absorbing demonstration device to solve the problem that the existing building model shock-absorbing demonstration device cannot simulate ground depression or ground vibration when it is in use. This limits the all-round simulation of shock absorption, and it is impossible to simulate the impact of ground vibration on architectural models. When the existing architectural model shock absorption demonstration devices are used, it is usually necessary to analyze architectural models of various specifications and sizes. Model simulation, unable to fix the problem of building models of different sizes
