[Industrial applications]

 The present invention relates to a waterproof structure for an outer wall of a house or the like formed by laying outer wall panels.

[0002]

[Prior art]

 The outer wall of a house or the like is formed by arranging a plurality of outer wall panels 1 vertically or horizontally, and at the joints between the outer wall panels 1 and other outer wall panels 1 and the joints between the outer wall panels 1 and the foundation 2. It is necessary to waterproof it so that rainwater does not enter the room. FIG. 3 (a) shows a waterproof structure at a joint portion between the outer wall panel 1 and another outer wall panel 1, and the other outer wall panel 1 is arranged on the upper surface of the outer wall panel 1 with the lower surface thereof facing each other. Between the lower surface of the outer wall panel 1 on the upper side and the upper surface of the outer wall panel 1 on the lower side, a heat insulating material 12 such as rock wool is arranged inside the roof, and a caulking support material 13 is provided on the outdoor side of the heat insulating material 12, It has a structure in which the caulking 11 is filled on the outdoor side of the support material 13. In this example, the upper surface of the caulking 11 contacts the lower surface of the upper outer wall panel 1 and the lower surface of the caulking 11 contacts the upper surface of the lower outer wall panel 1 so as to be waterproof. Further, FIG. 3B shows a waterproof structure in the joint portion between the outer wall panel 1 and the foundation 2. The outer wall panel 1 is disposed on the upper surface of the foundation 2 with the lower surfaces thereof facing each other, and A heat insulating material 12 such as rock wool is disposed on the indoor side between the upper surfaces of the outer wall panels 1, a caulking support material 13 is provided on the outdoor side of the heat insulating material 12, and caulking 11 is filled on the outdoor side of the caulking support material 13. It has a structure. In this example as well, the upper surface of the caulking 11 comes into contact with the lower surface of the upper outer wall panel 1 and the lower surface of the caulking 11 comes into contact with the upper surface of the foundation 2 to enable waterproofing.

[0003]

[Problems to be solved by the device]

 However, in any of the above examples, when the outer wall panel 1 thermally expands or contracts due to temperature change or the like, cracks may occur in the caulking 11, and rainwater may enter through the cracks and remain inside the heat insulating material 12 or the outer wall panel 1. There was a risk of invading the indoor side of.

The present invention has been made in view of the above points, and it is possible to ensure waterproofing even if the caulking is damaged, and the rainwater that has entered is collected inside or flows into the indoor side of the outer wall panel. The purpose is to provide a mounting structure for outer wall panels that can be eliminated.

[0005]

[Means for Solving the Problems]

 The mounting structure of the outer wall panel according to the present invention is such that the outer wall panel 1 is disposed on the upper surface of the lower base body 3 such as the outer wall panel 1 or the foundation 2 on the lower floor so that the lower surface faces the lower base body 3 and the outer wall panel 1. A long draining plate 4 is provided between the water draining plates 4, a waterproof body 5 is provided on the upper surface of the draining plate 4 for elastically contacting the lower surface of the outer wall panel 1, and the lower surface of the draining piece 4 is elastically contacting the upper surface of the lower substrate 3. A waterproof body 6 is provided, a water return piece 7 is provided at the outdoor end of the water draining plate 4, and a caulking support portion 10 is provided on the outdoor side of the water return piece 7 via a connecting piece 9 having a drainage portion 8. The caulking support portion 10 is filled with the caulking 11, and the caulking 11 is brought into contact with the lower surface of the outer wall panel 1.

[0006]

[Action]

 Since the caulking support portion 10 is filled with the caulking 11 and the caulking 11 is brought into contact with the lower surface of the outer wall panel 1, rainwater can be prevented from entering by the caulking 11. Further, on the indoor side with respect to the caulking 11, a waterproof body 5 elastically contacting the lower surface of the outer wall panel 1 is provided on the upper surface of the draining plate 4, and a waterproof body 6 elastically contacting the upper surface of the lower substrate 3 is provided on the lower surface of the draining piece 4. Therefore, the waterproof body 5 can prevent rainwater or the like from entering the indoor side through the gap between the draining plate 4 and the outer wall panel 1, and the waterproof body 6 can prevent the rainwater or the like from entering the indoor side through the gap between the draining plate 4 and the lower base body 3. Can be prevented. Further, since the water return piece 7 is provided at the outdoor end of the draining plate 4 and the caulking support portion 10 is provided on the outer side of the water return piece 7 through the connecting piece 9 having the drainage portion 8, the caulking 11 is damaged. Even if rainwater or the like enters, it can be removed from the draining portion 8 of the connecting piece 9.
