Shear force connection structure for lightning receptors

Abstract

The invention discloses a shearing force resistant connection structure for an air-termination system. The shearing force resistant connection structure comprises two lightning receiving rods opposite to each other, wherein opposite surfaces of the two lightning receiving rods opposite to each other are arc-shaped, connection blocks are also arranged at outer surfaces of side surfaces at ends of the opposite surfaces of the lightning receiving rods, and the two lightning receiving rods are connected by a spring between the connection blocks. By dividing an integrated lightning receiving rod into the two lightning receiving rods opposite to each other, connection parts are connected by the spring, the spring can be bent when a shearing force such as cross wind is applied, the lightning receiving rods are enabled not to be broken, and the lightning receiving rods are recovered under the effect of the spring during no wind and are enabled to be vertical and upward; and meanwhile, the opposite surfaces are arc surfaces and are beneficial for point discharge, namely, the two lightning receiving rods are not physically connected. The shearing force resistant connection structure has the advantages of excellent shearing force resistant performance, high safety and low improvement cost, the lightning receiving rods are enabled not to be broken by a shearing force, and an existing lightning receiving rod can be directly changed.

Description

technical field

[0001] The invention relates to an air-termination device, in particular to a shear force-resistant connection structure for the air-termination device. Background technique

[0002] The lightning protection device consists of lightning receptors, down conductors and grounding devices. The lightning receptor is located on the top of the lightning protection device, and its function is to use its protruding part higher than the protected object to guide the lightning to itself and receive the direct lightning discharge. The lightning terminal is composed of one of the following forms or any combination: independent lightning rod; lightning rod, lightning protection belt or lightning protection net installed directly on the building; permanent metal objects and metal roofs on the roof; steel bars in concrete components. In addition to using the internal steel bars of concrete members, the air-termination device should be galvanized, and the welding place shoul...
