[0002] In order to improve the thermal insulation effect, the metal roof eaves are usually equipped with thermal insulation cotton. After the metal roof eaves are assembled, the thermal insulation cotton is squeezed and deformed, so that its thickness is compressed, thereby reducing the thermal insulation effect and easily causing the cold bridge problem. Once the thermal insulation performance of the metal roof eaves is reduced, condensation water is easily generated on the indoor side, which has a certain impact on indoor equipment or goods. The existing atlas 17J925-1 does not involve the anti-cold bridge node structure for the metal roof eaves. Therefore, the inventor improved the metal roof eaves structure in the prior art to improve the thermal insulation performance of the roof, and this case was born. Utility Model Content

Among them, the surface of the wall panel 8 forms continuous concave and convex peaks and valleys, and the purlin 1 is located on the indoor side of the wall panel 8. The wall flashing 9 is formed into a horizontal plate and a vertical plate by bending. The horizontal plate is located between the bottom of the metal roof panel 7 and the top of the wall panel 8. The horizontal plate is parallel to the bottom surface of the metal roof panel 7 and extends to the indoor side. The vertical plate is parallel to the surface of the wall panel 8 and is located on the outdoor side of the wall panel 8. The thickness of the thermal insulation cotton 2 has a certain difference at different places, which includes a thin connecting section and a thick connecting section. The thermal insulation cotton 2 laid along the gap between the wall panel 8 and the purlin 1 is a thick connecting section.
