Description

A connection method between metal roof panel and gutter and waterproof eaves retaining board

technical field

The invention relates to the field of building prefabricated parts, in particular to a method for connecting a metal roof panel and a gutter and a waterproof cornice water retaining plate.

Background technique

Metal roof refers to the roof form that uses metal sheet as the roof material and combines the structural layer and waterproof layer into one. It is a new type of composite roof. Its products are used in large public buildings to factories, warehouses, and residences.

The metal sheets used in metal roofs are called metal roof panels. There are many types of metal roof panels, including zinc sheets, galvanized sheets, aluminum alloy sheets, aluminum-magnesium alloy sheets, titanium alloy sheets, copper sheets, and stainless steel sheets. The thickness is generally 0.4 ~ 1.5mm, and the surface of the board is generally painted.

Figure 1 is a schematic diagram of the cooperation between the metal roof panel and the gutter. As shown in Figure 1, the metal roof panel 100 generally has an inclination angle after installation, so that the rainwater flows down, and the gutter 200 is set at the foot of the metal roof panel 100, so that Collect rainwater.

FIG. 2 is a structural diagram of a metal roof panel. As shown in FIG. 2 , the structure of a metal roof panel is generally a plurality of repeated concave-convex structural units, and each concave-convex structural unit has a peak 101 and a trough 102 .

In actual use, although the metal roof panel 100 has an inclination angle and a gutter 200 for collecting rainwater is provided, rainwater may still enter the inner side of the metal roof panel because:
