A seismic test device for basic building frame model of wood structure buildings

Abstract

The invention provides an anti-seismic test device for a basic building frame model of a wooden structure building, and relates to the field of vibration testing devices. The anti-seismic test device for a basic building frame model of a wooden structure building comprises an outer sleeve, an inner sleeve, a The inner sleeve is arranged in the outer sleeve, the inner side of the outer sleeve is provided with slideways at equal angles around the axis, and the placing table is located above the inner sleeve. The anti-seismic test device for the basic building frame model of the wood structure building, through the cooperation of the rotating rod, the flap and the counterweight block, has the effect of blocking the internal passage of the sealed tank, and then uses the air pump to inflate the sealed tank to make the sealed tank The internal air pressure keeps rising until the top-opening flap pushes the piston rod up and hits the placing table, and then the air pressure is released from the vent hole to make the piston rod descend, thereby realizing the effect of up and down vibration. The inner sleeve vibrates in the horizontal direction through the cooperation of the connecting pipe, the rotating rod and the spring. Thus, multiple vibration effects are provided, and multiple realization data can be measured.

Description

technical field [0001] The invention relates to the technical field of vibration testing devices, in particular to an anti-seismic testing device for a basic building frame model of a wooden structure building. Background technique [0002] With the development of science and technology, people pursue retro architecture, and most retro buildings are framed by wooden structures. In the overall design process of the building, a small building model will be made, and through various tests on the building model, the overall building will be rectified according to the obtained data. Included in the test is a seismic test. [0003] For example, the "Dynamic Load Test Research Model of Circular Tulou Civil Structure" has been published in China Patent Network, with the patent number of 202010170453.4. The above-mentioned device includes a vibrating table board, a simulated earth wall placed on the vibrating table board, and a wooden frame supported on the inner side of the simula...
