The filling layer of the embodiment can be at least one of an insulating layer, a fire-proof layer and a sound insulation layer. For example: the fireproof rock wool is arranged in the cavity, so that the heat preservation effect can be achieved, and the fireproof purpose can be achieved. Or the polyurethane foaming material is injected into the cavity, thereby playing the roles of heat preservation and water resistance. And certain sound insulation and shock absorption effects can be achieved by filling the materials.

In this embodiment, the corrugated layer 1 includes a plurality of corrugated bodies 11, each corrugated body 11 of the corrugated layer 1 is provided along the length direction of the roof deck, the opening of the corrugated body 11 is downward, and the top wall and the side wall are both in contact with the filling layer 4. The top wall and/or at least one side wall is provided with a convex part, and the convex part can extend and protrude towards the direction of the filling layer and can also extend and protrude towards the direction far away from the filling layer. Preferably, the two side walls are provided with first protrusions 111 extending towards the filling layer 4, and the top wall is provided with second protrusions 112 extending away from the filling layer, and each protrusion preferably has an arc-shaped structure. Through setting up the convex part, when the shingle produced expend with heat and contract with cold by environmental impact, flute layer 1 can be through each convex part regulation of stretching out and drawing back to deformation can not take place.

As shown in fig. 3 and 4: in this embodiment, a corrugated unit 12 is formed between adjacent corrugated bodies 11, and adjacent corrugated units 12 are welded and/or glued integrally. Specifically, each corrugation unit 12 in this embodiment is a prefabricated structure, and if the roof deck is large, a plurality of corrugation units 12 can be spliced to form a larger corrugation layer 1. The splicing manner of the adjacent corrugated units 12 is preferably as follows: the lower edge 113 of the corrugated body at the tail end of one corrugated unit and the lower edge of the corrugated body at the starting end of the other corrugated unit 12 are stacked together and are connected into a whole by welding, wherein the tail end of the lower edge 113 of the corrugated body 11 at the tail end of one corrugated unit is provided with a bending structure 114, and after the two lower edges 113 are welded, glue is applied to the bending structure 114, so that the connecting strength and the sealing property are further improved, and water is prevented from entering.
