Abstract

The invention discloses a loading platform device for explosion damage experiments of civil engineering structures, which includes a platform frame, and is characterized in that a blasting baffle is arranged on the platform frame, a hook frame is arranged at the upper end of the platform frame, and a hook frame is arranged inside the hook frame. There are hook support rods distributed in an array, and a hook machine is jointly arranged on the hook support rods. A lower frame distributed in an array is arranged on one side of the lower part of the platform frame, and a blasting vehicle frame, a first weight frame and a The second weighted frame, the blasting vehicle frame is provided with a mirrored distribution of blasting vehicles, the blasting vehicles are jointly equipped with a blasting carrier plate, and the lower end of the second weighted frame is provided with supporting rollers distributed in an array. The structure of the invention is simple and easy to operate, and at the same time, it is convenient for operators to move to an open place for experiments, which reduces the risk of explosion damage experiments, facilitates adjustment of the distance between explosives and experimental structures, facilitates control of experimental variables, and improves the accuracy of experiments. It is beneficial to provide important data for building construction.

AI Technical Summary

Problems solved by technology

All non-military civil engineering projects have been classified into this category. The explosion damage test of civil engineering is an important means to explore the structure under load. The explosion is a special load, and the main feature is the local shock wave in a short time. Excitation is different from the static properties of structural dead load, and also different from the full-structure excitation of seismic load and dynamic load. Due to the danger of explosion experiment itself and the strict control of drug circulation, explosion experiments in the field of civil engineering structures are seldom carried out. Most of the experiments carried out are based on chemical and pharmaceutical experimental platform devices. At present, no loading platform method for structural experiments in this field has been developed, which seriously restricts the experimental research on the performance of civil engineering structures such as beams, slabs, and columns under the action of explosions.
