Lightning protection device for high-rise building

Abstract

The invention discloses a lightning protection device for a high-rise building, and the lightning protection device comprises a lightning rod body, a base and a concrete fixed seat; a through hole is formed in the center of the top end of the base, the bottom end of the lightning rod body is welded in the through hole, and the base is poured in the concrete fixed seat. A plurality of evenly-distributed stabilizing rods are welded to the side wall of the bottom end of the lightning rod body, the stabilizing rods are obliquely arranged, the bottom ends of the stabilizing rods are welded to the top end of the base, a plurality of transverse rods are arranged on the side wall of the lightning rod body, vertically-arranged fastening rods are welded to one ends of two of the transverse rods, and the fastening rods are located at the top ends of the stabilizing rods. An annular plate is welded to the side wall of the lightning rod body, the annular plate is located above the cross rod, and the side wall of the annular plate is slidably sleeved with an annular block. The device is simple in structure, novel in design, high in stability, capable of adjusting the lightning protection range, good in lightning protection effect and suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of lightning rods, in particular to a lightning protection device for high-rise buildings. Background technique [0002] Lightning rod, also known as lightning rod, is a device used to protect buildings, tall trees, etc. from lightning strikes. Install an air-termination device on the top of the protected object, and connect it with the underground drain grid with a wire that meets the specifications. The specifications of the lightning rod must comply with the GB standard, and the height specifications of the lightning rod required by each lightning protection category are different. As the thundercloud discharge approaches the ground it distorts the ground electric field. At the top of the lightning rod, a space where the local electric field is concentrated is formed to affect the development direction of the lightning pilot discharge, guide the lightning to discharge to the lightning rod, and then intr...

AI Technical Summary

Problems solved by technology

[0003] The existing lightning rods are generally rod-shaped structures, which are vertically fixed at the designated installation position during installation, and the effective lightning protection range is often very small during use, which cannot meet the lightning protection requirements under many conditions. To improve the lightning rod device, we propose a lightning protection device for high-rise buildings
