To achieve the purpose, the invention provides a rigid platform for a heavy impact load test, which comprises a steel plate, bolts, nuts, supporting legs and concrete, wherein:
the steel plate is formed by splicing more than 2 steel plate modules, and bolt holes are formed in the splicing and overlapping positions between the adjacent steel plate modules; the bolts penetrate through bolt holes in the two adjacent steel plate modules and are screwed and fixed with the nuts so as to enable the adjacent steel plate modules to be tightly connected; the lower end of the supporting leg is fixed on the foundation, and the upper end of the supporting leg is fixedly connected with the steel plate and supports the steel plate; the concrete is poured between the steel plate and the foundation, and the steel plate is provided with an exhaust hole for exhausting gas during concrete pouring; and after the concrete pouring is finished, sealing and welding all the bolt holes and the exhaust holes.
Furthermore, the splicing and overlapping parts between the steel plate modules are all provided with mounting, positioning and overlapping grooves with bolt holes.
Further, the rigid platform also comprises a screw and/or a plug, and after concrete pouring is completed and before the exhaust hole is sealed and welded, the screw and/or the plug are installed at the exhaust hole for plugging.
Furthermore, the steel plate and the upper end of the supporting leg are fixedly connected by welding or screwing the bolt and the nut.
Furthermore, the lower ends of the supporting legs are connected and fixed on a foundation through foundation bolts.
The rigid platform for the heavy impact load test has the advantages that a large-size and large-thickness steel plate can be split into a plurality of steel plate modules by the rigid platform for the heavy impact load test, so that the steel plate can be conveniently processed, transported and installed; the adjacent steel plate modules are positioned and assembled by adopting lap joint grooves so as to ensure the smoothness of the splicing positions of the steel plate modules; the adjacent steel plate modules are connected and fixed by bolts and nuts, so that the defects of large residual stress, need of postweld heat treatment and the like of butt welding of large-thickness steel plates are overcome; the steel plate is provided with a plurality of exhaust holes, so that gas is conveniently exhausted when concrete is poured, and a gap between the lower surface of the steel plate and the concrete is avoided, so that the rigidity of the platform is ensured; and after the pouring is finished, the exhaust holes in the steel plate are blocked by screws and/or plugs, and finally, all the bolt holes and the bolt hole positions are sealed and welded to prevent rainwater, dust, sundries and the like from entering.
