Problems solved by technology
[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a thermal insulation and waterproof roof to solve the existing problem that if the roof is located at a high place, it is easy to be struck by lightning, because the lightning can generate a relatively high counterattack voltage when the current is released. Electrostatic grounding can introduce counterattack voltage into the electrostatic protection area, causing safety accidents and equipment damage, and the problem of low safety performance

Embodiment Construction
[0016] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0017] see Figure 1-Figure 2 , the present invention provides a technical solution: a thermal insulation and waterproof roof, the structure of which includes a steel bar 1, a lightning protection device 2, a steel plate 3, a roof membrane 4, an insulation layer 5, an air barrier membrane 6, a polyurethane foam protective layer 7, and a drainage device 8. Waterproof layer 9. The steel bar 6 is a rectangle with a length of 250-300cm. There are two steel bars. The foam protection layer 7 is a rectangular panel with a length of 300 cm. The left and right ends of the upper surface of the steel bar 1 are respectively connected with the lightning protection device 2 in an interference fit mode. The lightning protection device 2 is a rectangular parallel...

Abstract
The invention discloses a thermal insulation and waterproof roof, the structure of which comprises a steel bar, a lightning protection device, a steel plate, a roof membrane, a thermal insulation layer, an air barrier film, a polyurethane foam protective layer, a drainage device, and a waterproof layer. The steel bar is 250-300 cm long. There are two rectangles, the upper ends of the steel bars are respectively connected with the inner surface of the polyurethane foam protective layer by means of interference fit, and the polyurethane foam protective layer is a rectangular panel with a length of 300cm; the lightning protection device consists of a horizontal Bearing, arc rod, insulated wire, insulating shield, insulating tube. The beneficial effect of the present invention is that a lightning protection device is provided, and the lightning current is discharged into the ground through the arc striking rod and the cross arm, so that the protected object is protected from lightning strikes, and the high counterattack caused by the lightning discharge current to the building is solved. Voltage, resulting in damage to electrical equipment, resulting in safety accidents, high safety performance.
Description
technical field [0001] The invention relates to a thermal insulation and waterproof roof, which belongs to the technical field of construction equipment. Background technique [0002] The roof is the surface of the roof of the building. It mainly refers to the part between the ridge and the eaves. This part occupies a larger area of the roof, or the roof is the larger part of the roof. [0003] The prior art discloses a thermal insulation and waterproof roof with the application number of CN201020554364.1, which includes thermal insulation sandwich panels. The insulation layer is filled between the boards, and it is characterized in that the outer board is a flat board, the inner board is provided with strip-shaped convex ribs evenly spaced, and the two ends of the inner board are respectively provided with corresponding lap joints. The groove-and-groove structure, adjacent thermal insulation sandwich panels are overlapped by the groove-and-groove structures provided at b...
