[0019] The present invention is described in detail with reference to the best embodiment below.

[0020] like Figure 1-4 As shown in the figure, a lightning protection device for repairing the metal roof of an ancient building is provided. A metal roof 2 is set on the top of the ancient building 1. The metal roof is used to repair the ancient building. The metal roof refers to a roofing form that uses metal plates as roofing materials and combines the structural layer and the waterproof layer into one. There are many types of metal plates, including galvanized plates, aluminum-zinc plates, aluminum alloy plates, aluminum-magnesium alloy plates, titanium alloy plates, copper plates, stainless steel plates, etc. The surface of the plates can be painted. The metal roof panels can be assembled on site after being processed in the factory, and can be manufactured into various structures to meet the needs of the style of ancient buildings.

[0021] Conductive plates 3 are respectively arranged on the upper and lower edges of the metal roof 2. The upper conductive plate 3 is a straight plate structure, and the lower conductive plate 3 is a curved plate structure. Bolts pass through the metal roof 2 and the conductive plate 3 to fix the upper and lower conductive plates 3 and the metal roof 2 together; the curved plate part of the lower conductive plate 3 is connected to the down conductor conductive plate 4 by bolts, and the down conductor conductive plate 4 is attached and fixed to the surface of the outer wall of the ancient building 1. The lower end of the down conductor conductive plate 4 is welded to the down conductor 5; the outer surface of the down conductor 5 is covered with an insulating tube 6, and the insulating tube 6 is fixed on the outer wall of the ancient building 1 by open laying; or the insulating tube 6 is buried in the wall of the ancient building 1 by concealed laying, and the down conductor conductive plate 4 is inserted; open laying or concealed laying is determined according to the requirements of the ancient building repair. The lower end of the down conductor 5 is connected to the grounded metal conductor 7 underground.

[0022] This utility model is different from the traditional practice of burying a large number of lightning protection brackets on the roof of the prior art. It uses the good conductivity of metal to repair ancient buildings with metal roofs, and uses them as lightning conductors. Then, they are connected to the grounding device through a Φ12 galvanized round steel down conductor or a galvanized flat iron down conductor buried in the plaster layer of the exterior wall. The down conductor used is a metal conductor that discharges lightning current from the lightning rod into the grounding device. The down conductor should be laid openly along the exterior wall of the building and grounded through the shortest path. It can be laid concealed if the architectural art requirements are higher, but the diameter of the round steel should not be less than 10mm, and the cross-section of the flat steel should not be less than 80mm2

[0023] The construction method of using the metal plate of the slope roof as a lightning connection medium can ensure the quality of the project to a certain extent, reduce the later maintenance, save labor, shorten the construction period, and improve the efficiency by 10%-15%. It is easy to operate, fast in construction, and high in quality of finished products. It can also avoid the installation of lightning protection brackets in traditional lightning protection methods, which causes a large number of weak points in waterproofing. In terms of economic benefits, the lightning connection and lightning protection construction method of the metal roof of the ancient building optimizes the method to save materials and labor while ensuring the function, saving construction costs from both labor and material aspects.
