Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to FIG. 1, a first preferred embodiment of the waterproof lap panel 200 of the present invention comprises a lap body 2 and two extension panels 3.

The lap plate body 2 includes a water guiding portion 21 having a groove shape, and a water blocking portion 22 disposed at an upstream end of the water guiding portion 21 and inclined upwardly, wherein the water guiding portion 21 has a "V" shape in cross section. There are two first parallel sides 211 and a second side 212.

The two extension plates 3 extend outward from the first side 211 and the second side 212 of the water guiding portion 21 of the overlapping body 2, respectively. Each of the extension plates 3 has a flat-shaped overlapping portion 31 for being superposed on the corresponding wave plate 11 (see FIG. 2), and one end of the water retaining portion 22 of the overlapping body 2 is adjacent to the overlapping portion 31. A stepped fixing portion 32 that is bent and extends in parallel with the water blocking portion in the oblique direction.

In this embodiment, the overlapping body 2 and the extension plate bodies 3 are all made of a flexible material (for example, steel or aluminum), and the extension plates 3 are respectively along the first place according to site requirements. The side 211 or the second side 212 is bent upward or downward.

Referring to FIG. 2 and FIG. 3 , the waterproof lap plate 200 of the present invention is installed between the two wave plates 11 , because the wave plates 11 have a slope during installation, and during installation, and because the lap body 2 The water guiding portion 21 can be retracted and slightly inserted into the gap 14 of the two waves 11 , and then the water guiding portion 21 is outwardly extended, so that the two extending plates 3 are attached to each other. The top surfaces of the two waves 11 can be installed. It is worth mentioning that, in this embodiment, a protective cover 5 detachably covers the water guiding portion 21 of the overlapping body 2 is further included. Under normal conditions of use, rainwater may flow in the water guiding portion 21 without flowing into the gaps of the two waves 11 to cause water leakage. Further, since the water retaining portion 22 is designed to extend obliquely upward and is located upstream of the water guiding portion 21, it is possible to assist in introducing rainwater into the water guiding portion 21, and it is not easy to flow to other places. Furthermore, since the overlapping body 2 and the extending plate bodies 3 are made of a flexible material, even if the temperature difference changes outside, the wave plates 11 are thermally expanded and contracted to change the size of the slits 14 . The overlapping body 2 can still exert its efficacy to avoid leakage.

Firstly, the water guiding portion 21 of the overlapping device 2 is placed in the gap 14 between the wave plate 11 and the wall surface 12, but only one side of the wave plate 11 is provided for the extending plate extending outward from the second side 212. The body 3 is mounted, so that the extension body 3 extending outward from the first side 211 of the overlapping body 2 is bent upward along the first side 211 at this time (as shown in FIG. 4) to fit the wall. Face 12, this completes the installation. After the installation is completed, the water can also be provided to the water guiding portion 21 of the overlapping body 2 without flowing into the gap 14 between the wave board 11 and the wall surface 12, and the water is blocked. The water portion 22 can also effectively introduce rainwater into the water guiding portion 21, and does not easily flow to other places. Moreover, since the overlapping body 2 and the extension plate bodies 3 are all made of a flexible material, even if the external temperature difference changes, the wave plate 11 is thermally expanded and contracted, and the gap 14 is increased or decreased. The lap body 2 can still exert its function to avoid water leakage. The situation happened.

Please refer to FIG. 6 , which illustrates an embodiment in which the waterproof lap panel 200 of the present invention is disposed between two vertically spaced wave plates 11 and adjacent wall surfaces 12 .
