Demonstration device simulating seismic insulation of building

Abstract

The invention discloses a demonstration device simulating seismic insulation of a building. The demonstration device comprises a shaking base and a building model arranged on the shaking base, whereinthe shaking base comprises a base body and an attachment support plate mounted on the base body in a swingable manner, and elastic swing reset pieces are connected between the attachment support plate and the base body; the building model comprises N floor modules stacked layer by layer from bottom to top, and the floor module on the bottommost layer is fixedly connected with the attachment support plate. When the demonstration device is used for simulating earthquake damage, the attachment support plate swings horizontally relative to the base body, the building model on the attachment support plate deforms due to the swing, deformation is shown on a deformed wallboard directly, an observer can observe the damage action of seismic transverse-waves on the building model quite directly andvividly, external force is eliminated after simulation, the attachment support plate can reset under driving of the swing reset pieces, and next simulation observation is facilitated.

Description

technical field [0001] The invention relates to a teaching simulation device, in particular to a demonstration device for simulating building shock isolation. Background technique [0002] Earthquakes are shock waves generated by sudden ruptures inside the earth, causing ground vibrations within a certain range. Earthquakes are natural disasters with huge destructive power, which can cause great loss of life and property. If effective measures can be taken to reduce The dynamic response of the structure caused by the earthquake can effectively reduce the structural damage caused by the earthquake, reduce the large cost of the structure for earthquake resistance, and reduce the loss of life and property. Therefore, building vibration isolation and shock absorption is an important structural disaster reduction measure. At present, the shock absorption methods mainly include: rubber bearing isolation, swing bearing isolation, tumbler isolation house, damper, energy dissipation...

Problems solved by technology

It is often necessary to explain the seismic isolation measures in teaching. The current popular science teaching methods are generally teachers' lectures, books, texts and posters, etc., with many professional terms, no field inspection experience, and no real objects. Lack of understanding of seismic technology
