In addition, since lightning rods and lightning arresters need to be installed on roofs and exposed high places, the exposed grounding device will affect the decorative effect and appearance after welding.

The present invention can also be implemented or applied by other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and the features in the embodiments can be combined with each other without conflict. It should be noted that similar reference numerals and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further defined and explained in the subsequent figures.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0027] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0028] refer to Figure 1 and Figure 2 As shown in the figure, a jumper lightning protection grounding device is shown, including: a wall structural column 1 or a structural column (containing steel bars), a wall decorative surface layer 2, a lightning protection down conductor 3, a voltage equalizing ring 4, a connecting sleeve 5, a fastening bolt 6, a grounding clamp 7, a lightning arrester 8, a lightning rod 9, a jumper wire 10, and a connecting bolt 11.

[0029] Preferably, the down conductor 3 is pre-buried in the wall structural column 1, one end of the connecting sleeve 5 is pre-buried in the wall structural column 1, and the other end extends out of the wall structural column 1; the lightning rod 8 is connected and fixed to the exposed end of the connecting sleeve 5 via a grounding clamp 7, and one end of the jumper wire 10 is wrapped around the lightning rod 8, and the other end passes through the connecting sleeve 5 to be connected to the down conductor 3.

[0033] Preferably, a sealing structure is provided at the exposed port of the connecting sleeve 5 to complete the waterproof sealing of the port. For example, waterproof sealing materials such as raw tape are wrapped around the outside of the grounding clamp 7, or sealed with weather-resistant glue to prevent water from invading the connecting sleeve 5 and corroding the wire body.

[0034] Preferably, the lightning receptor 8 is a galvanized round steel or a copper tube or an aluminum tube, and the lightning receptor 8 is arranged perpendicular to the grounding clip 7 .

[0035] Preferably, the wall surface of the lightning receptor 8 is in surface contact connection with the grounding clamp 7 , and the jumper wire 10 is crimped onto the lightning receptor 8 by the grounding clamp 7 .

The utility model ensures the lightning protection grounding effect through a lightning protection net. A voltage-equalizing ring shall be arranged in the roof parapet or the roof panel, and a closed inner ring shall be formed by welding horizontally connected steel bars. After the voltage-equalizing ring is formed, the lightning on the same floor or at a high place shall be connected to the ground, and a down conductor 3 is required.

Since the steel bar welding points are all wrapped and cast with concrete, they have strong anti-corrosion and weather-resistant properties.

In combination with decoration, the outer side of the wall structural column is made into a decorative surface layer 2, and only a small hole needs to be opened to cover it from top to bottom, and the finished product has a good effect.
