Model testing device for building safety

Abstract

According to the technical scheme, the model testing device for building safety is characterized in that the model testing device comprises a fixed box, an installation block is fixedly installed on the inner wall of the fixed box, and a first sliding groove is formed in the side wall of the installation block; the first electric push rod pushes the support plate to move; the second electric push rod drives the push block to move, and the first striking block is clamped between the clamping block and the push block; the first electric push rod retracts to drive the first striking block to move to a certain distance; the second electric push rod retracts to separate the push block from the first striking block, and the elastic force of the first elastic rope enables the first striking block to rapidly rebound; and then, the first impact block collides with the cushion block to generate vibration, the effect of generating longitudinal impact force is achieved, the second impact block collides with the fixed block in the same mode to generate transverse impact force, and therefore the earthquake simulation effect is achieved; wherein the impact force can be adjusted by adjusting the moving distance of the first impact block and the second impact block, so that earthquakes of different levels are simulated. According to the invention, the test comprehensiveness is improved.

Description

technical field [0001] The invention relates to the field of building safety model testing, in particular to a model testing device for building safety. Background technique [0002] Steel structure buildings refer to buildings that use steel plates or section steel instead of traditional reinforced concrete buildings. Steel structure buildings have higher strength and better earthquake resistance, so they are now widely used. Steel structure buildings will be manufactured before construction. The same physical model or It is a graphic model for performance analysis, and a test device is required for the analysis and test of the seismic performance of the physical model. [0003] However, there are some deficiencies in the testing devices in the prior art. First, the vibration mode is usually fixed, and the vibration frequency cannot be adjusted according to the magnitude, resulting in insufficient comprehensive testing of the model. In building construction, the foundation ...

[0003] However, there are some deficiencies in the testing devices in the prior art. First, the vibration mode is usually fixed, and the vibration frequency cannot be adjusted according to the magnitude, resulting in insufficient comprehensive testing of the model. In building construction, the foundation has natural foundation and artificial foundation. , but the existing test devices cannot be tested according to different foundations, resulting in differences between the test results of the model and the actual construction, which affects the safety of the building
