Steel connector box with anti-floating structure

Abstract

The anti-floating structure steel connector box comprises a steel box, a cavity is formed in the steel box, and an open hole is formed in the bottom of the steel box; the spring is arranged in the steel box, the upper end of the spring is fixedly connected to the top end in the steel box, the end steel plate is fixedly arranged at the lower end of the spring, the annular rubber pads are fixedly arranged on the two sides of the lower end of the end steel plate, and the lower ends of the annular rubber pads are fixedly connected to the bottom end in the steel box; bottom plate steel bars are arranged in the bottom plate, and the steel box is welded to the bottom plate steel bars; steel bars are arranged in the anti-floating structure, the upper ends of the steel bars are connected with the bottom end of the steel plate in a welded mode, and the steel bars and the steel plate are welded in a perforation welding mode. Compared with the prior art, the anti-floating structure has the advantages that the anti-floating structure does not participate in anti-floating contribution in the daily water level amplitude variation process; only under the extreme climate condition, the site water level exceeds the designed water level, the emergency anchor rods play the emergency anti-floating effect, and the anti-floating safety of the underground structure is guaranteed.
