How to make the roof lightning protection belt of aluminum alloy slab slope roof curtain wall?

Lightning protection node installation:

(1), according to the drawing requirements, materials should be selected, and galvanized round steel with a diameter of Ф12mm and stainless steel arrester with a thickness of 1mm should be adopted.

(2), galvanized round steel and horizontal and vertical main structure of the reserved lightning protection point lap, double-sided welding length is not less than 80 mm ..

(3), every three layers should be added with a circle of transverse closed lightning rod, and should overlap with each embedded part;

(4), at the junction of each large angle and vertical lightning rod, use Ф12mm galvanized round steel for lap joint;

⑤ Set a circle of closed lightning rod at the parapet and tower top of each floor of the main building, overlapping with the vertical lightning rod of the curtain wall.

6. The vertical lightning rod on the first floor is overlapped with the grounding flat iron of the main structure, with the overlapping length of 80mm and double-sided welding.

⑦ The transition parts of aluminum columns and steel columns and the expansion parts of vertical joints of each column are connected by stainless steel lightning arresters.

⑧ When installing lightning arrester, the coating on the surface of aluminum profile and galvanized steel shall be cleaned by angle grinder, so as to ensure full contact of lightning arrester and achieve conductive effect. The contact surface should be smooth and fixed with four M5 * 20mm self-tapping nails.
