Abstract

The invention relates to a lightning protection metal roof and a construction method thereof, and belongs to the field of building construction. The lightning protection metal roof is composed of a metal roof panel, a leveling steel plate, a supporting profiled steel plate, a square pipe purline, stainless steel fasteners, a duct corner, and a pre-embedded steel plate. The lightning protection metal roof has the advantages of simple structure and convenient operation, and uses the metal roof panel itself as a lightning protection net to electrically connect the metal roof panel and the reinforcement mat of the roof main body concrete structure to form a passage, thereby eliminating the need to weld the steel bar extending out of the roof surface into a mesh shape, greatly reducing the construction difficulty, saving construction cost, enhancing the waterproof effect and avoiding accidents caused by snow falling in the snowstorm weather.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a multi-lightning protection metal roof and a construction method. Background technique [0002] As an important function of construction engineering, lightning protection plays a role in protecting personal safety and property safety of electrical equipment. [0003] Lightning protection is generally composed of lightning protection nets, down conductors, and grounding devices. The lightning protection nets are generally drawn from the steel bars in the main structure of the roof, and the protruding roof is welded into a mesh shape. The protruding roof will generally cause damage to the waterproof layer or increase construction. At the same time, there will be lightning protection nets to catch the snow in heavy snow, and the snow will pull the lightning protection nets and roof tiles to fall off due to too much snow, causing personal and property losses.
