BACKGROUND Technical Field The invention relates to the field of civil engineering experiments, and more particularly, to a loading platform device for an explosion injury experiment of a civil engineering structure. Related Art Civil engineering is the planning, construction and maintenance of all infrastructure related to culture, soil and water, and refers to the survey, planning, design, construction and other technical work carried out for new construction, reconstruction or expansion of various types of engineering buildings and related supporting facilities, and completed engineering entities in addition to building construction. Common civil engineering projects include: energy, water conservancy, transportation facilities and the like. Once all civil engineering projects for non-military purposes were included in this category, a civil engineering explosion injury experiment is an important means to explore the structure under load, the explosion is a special load, and the main feature is the local excitation of shock waves in a short time, which is different from the static nature of a dead load of the structure and also different from the full structure excitation of a seismic load and a dynamic load. Due to the danger of the explosion experiment and the strict control of the drug circulation, there are few explosion experiments in the field of civil engineering structure. Most of the experiments carried out are based on a chemical drug experimental platform device. At present, there has not been developed a loading platform method for a structural experiment in this field, which severely restricts the performance experiment research on civil engineering structures such as beams, slabs and columns under the explosion. In view of this situation, a loading platform device for an explosion injury experiment of a civil engineering structure is now proposed.
