Assembling type large-scale vibrating table test protection device

Abstract

The invention discloses an assembling type large-scale vibrating table test protection device comprising an anchoring structure and a vibrating table protection frame erected on the anchoring structure. The anchoring structure includes concrete anchor blocks and stand columns anchored on the concrete anchor blocks; the vibrating table protection frame includes steel frames fixedly mounted on the stand columns, the steel frames include Bailey truss girders erected on the stand columns and Bailey truss auxiliary beams fixedly mounted on the girders, the Bailey truss auxiliary beams includes horizontal Bailey truss beams and vertical Bailey truss beams, and the horizontal Bailey truss beams and the vertical Bailey truss beams are erected on the Bailey truss girder to form a double cross shaped structure for placing a vibrating table. The assembling type large-scale vibrating table test protection device has the following advantages: according to the invention, a space-enclosed frame is formed on the neck of a test model, and when the test structure collapses, the safety protection device can clamp a test piece in time; the characteristics of simple assembly and hoisting are achieved;since the shuttle space of the safety protection device is large, a layout platform can be provided for a test sensor, and thus testers can conveniently operate and observe test phenomena.

Description

technical field [0001] The invention relates to the technical field of vibration test safety protection, in particular to an assembleable large-scale vibration table test protection device. Background technique [0002] Large-scale shaking table test is an important test technique in earthquake engineering research. When carrying out elastic-plastic seismic response failure simulation tests of large-scale or full-scale structural models, in order to ensure the safety of personnel and equipment during the test, it is often necessary to design safety protection devices. The safety protection device should fully consider various possible adverse conditions (structure collapse, weight falling), so that the designed protective structure can reliably resist these adverse conditions. Therefore, how to design a safe and reliable device with sufficient strength and stability to resist the impact force when the test structure collapses, and at the same time, have sufficient rigidity ...
