Embodiment Construction

[0013] Such as Figure 1-Figure 2 As shown, a lightning rod for high-rise buildings includes a needle bar 1, a metal ball 2 and a needle tip part 3, an insulator 4 is fixed on the bottom of the metal ball 2, and the insulating character 4 is made of ceramics, and a round hole is provided inside, so that the needle bar 1 The top can go through. The metal ball 2 and the insulator are welded by brazing process, which can keep the surface of the joint clean, good air tightness, stable shape and size, the structure and performance of the weldment do not change much, and the same or different metals and some non-identical parts can be connected. Metal. During brazing, the overall heating of the workpiece can also be used, and many welds can be welded at one time, which improves the productivity. However, the strength of brazed joints is low, and lap joints are mostly used, and the strength of the joints is increased by increasing the length of the lap; in addition, the preparation...

Abstract

The invention discloses a lightning arrester of a high-rise building. The lightning arrester comprises a needle rod, a metal ball and a needle tip part, wherein an insulator is fixedly arranged at the bottom of the metal ball, the top of the needle rod penetrates through the insulator and is welded with the metal ball, the needle tip part is welded at the top of the metal ball, a strut is welded with an outer side of the metal ball, a connection rod is welded with a tail end of the strut, a metal sleeve is arranged at the middle part of the connection rod, horizontal rods are respectively welded at an upper end and a lower end of the metal sleeve, a vertical rod is welded between the two horizontal rods, a flange disc is welded at the bottom of the needle rod, thread holes are uniformly formed in the flange disc, a copper woven belt is arranged at one side of the flange disc, and line noses are welded at two ends of the copper woven belt. The lightning arrester of the high-rise building is good in flash effect, simultaneously has a heat dissipation function and is convenient to install.

Description

technical field [0001] The invention relates to a lightning rod for high-rise buildings. Background technique [0002] Existing lightning rod, has another name called lightning protection rod, is the device that is used to protect buildings, tall trees etc. from being struck by lightning. Install an air-termination device on the top of the protected object, and connect it with the ground discharge grid buried underground with wires that meet the specifications. The specification of the lightning rod must comply with the GB standard, and the height specification of the lightning rod required by each lightning protection category is different. When a 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 influence the development direction of the lightning pilot discharge, guide the lightning to discharge to the lightning rod, and then introduce t...
