Problems solved by technology

[0004] The technical problem to be solved by this invention is that most of the existing lightning rods are made of rigid materials, so the vertically upward lightning rods may be broken when affected by cross winds, which will reduce the lightning protection performance of the building. The shear connection structure solves the problem that the lightning rod is easily broken by shear force

Embodiment

[0019] Such as figure 1 As shown, the lightning-terminating device of the present invention uses a shear force connection structure, including two air-terminating rods (1) with a diameter of 8cm facing each other, and the two lightning-terminating rods (1) are 10cm apart, and the two opposing lightning-terminating rods (1) are 10cm apart. The opposite side (101) of the lightning rod (1) is inferior arc, and the outer surface of the side at the end directly opposite of the lightning rod (1) is also provided with a connecting block (2) with a length of 5 cm matching the shape of the outer surface. ), the connection block (2) protrudes from the outer surface by 2cm, and the two lightning rods (1) are connected by a spring (4) between the connection blocks (2). The number of connecting blocks (2) on the two lightning rods (1) is the same, and the positions are facing one by one, and the spring (4) is connected between the two connecting blocks (2) facing each other. Each lightnin...

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...
