Civil engineering structure anti-seismic test device with adjustable vibration direction

Abstract

The invention discloses a civil engineering structure anti-seismic test device with an adjustable vibration direction, which comprises a main body, can reasonably simulate the state during an earthquake so as to increase the accuracy of a model during detection, and is characterized in that a rotatable rotating ring is arranged in a mounting seat, so that the seismic wave of the model in the transverse direction can be effectively adjusted; and the model can receive the impact of transverse seismic waves in different directions, so that the detection work is well completed, an arc-shaped beating block continuously beats a T-shaped connecting block in the current direction, or T-shaped connecting blocks in different directions are continuously beaten through a stepping motor, so that the obliquely upward seismic waves are well simulated, and meanwhile, a transfer box is arranged on the second piston cylinder, and a water pump in the transfer box can pump out or increase water in the first piston cylinder, so that the initial positions of the first piston block and the ejector rod can be adjusted, and seismic wave simulation of different degrees is realized.

Description

technical field [0001] The invention relates to the field of anti-seismic test devices, in particular to an anti-seismic test device for civil engineering structures with adjustable vibration direction. Background technique [0002] China has a vast land area and diverse topography, so there are many earthquake zones. According to past experience, the blows caused by earthquakes to human beings are devastating. Therefore, the current civil engineering structures have anti-seismic functions. After the civil engineering structure needs to be subjected to seismic detection test, in order to estimate the seismic capacity of the civil engineering structure when an earthquake occurs. [0003] However, when the existing device is used for seismic performance testing, the vibration direction is relatively single, and it cannot effectively and reasonably detect the overall seismic performance of the house under the condition of various different seismic waves. At the same time, the v...

Problems solved by technology

[0003] However, when the existing device is used for seismic performance testing, the direction of vibration is relatively single, and it cannot effectively and reasonably detect the overall seismic performance of the house under the conditions of various different shock waves. At the same time, the vibration direction cannot be adjusted. When the device is working , the resulting vibration will easily cause the whole detection device to shake together with it, affecting the detection effect
