The invention relates to a
lightning-proof ground structure for a high-rise building. The
lightning-proof ground structure includes a
copper sheet conduction belt, an
aluminium sheet conduction belt,a switching device, and
copper sheet switching belts. The
copper sheet conduction belt and the
aluminium sheet conduction belt are pre-embedded inside a building from bottom to top. The copper sheet conduction belt is fixedly connected to a reinforcing
steel bar mesh in the foundation of the building. The copper sheet conduction belt extends upwardly and passes through the switching device to be fixedly connected to the
aluminium sheet conduction belt. The aluminium sheet conduction belt reaches the roof directly, and the external surface of the aluminium sheet conduction belt outside the switching device is wrapped in an insulator. The building is provided with a plurality of conduction assisting
layers, the aluminium sheet conduction belt of the conduction assisting
layers is connected by the switching device, the switching device is also connected to the copper sheet switching belts, and the copper sheet switching belts are fixedly connected to reinforcing steel bars in the building. The
lightning-proof ground structure is simple, is easy to manufacture and install, and is easy to carry since aluminum sheets can be easily bent. The
current conduction efficiency is achieved, thestandard conduction effect is achieved, the problem of
welding of each layer is avoided, and the construction speed of
a site is effectively accelerated. The high process is satisfied, and the cost isreduced.
