  In view of the necessity as described above, the present invention provides an outer insulating heat insulating ventilation that can reliably prevent moisture in the ventilation layer between the exterior material and the outer heat insulating material from entering the building. It is an object of the present invention to provide an outer wall panel and an outer heat insulating ventilation outer wall structure.

  The above-described problem is that an outer heat insulating material is provided between the panel frame and the outer covering material, and a ventilation layer is formed between the outer insulating heat insulating material and the outer covering material on the side of the outer insulating heat insulating material. A spacer extending in the vertical direction is provided, and a waterproofing material is provided between the side spacer and the outer heat insulating material to prevent water movement between them. This is solved by the tension insulation ventilation outer wall panel (first invention).

  Further, a spacer extending in the vertical direction for forming a ventilation layer is provided between the outer heat insulating material and the outer covering material on the side of the outer heat insulating material, and the side spacer and the outer heat insulating material This is solved by the outer heat insulating ventilation outer wall structure characterized in that a waterproof material is interposed between them to prevent the movement of water between them (second invention).

  In these inventions, since the waterproof material is interposed between the side spacer forming the ventilation layer and the outer heat insulating material, the waterproof material allows moisture in the ventilation layer to be absorbed by the side spacer and the outer coating. You can prevent it from entering the inside of the building by going around the side of the outer insulation through the insulation, and ensure that the moisture in the ventilation layer enters the inside of the building Can be prevented.

  1st and 2nd invention WHEREIN: The said outer-layer heat insulating material consists of a board-like fiber-type heat insulating material, This board-like fiber-type heat insulating material equips the outdoor side surface part with a moisture-permeable waterproof sheet, and the said water-proof material is It is good to interpose between this moisture-permeable waterproof sheet and the said spacer (3rd invention).

In this case, moisture in the room can be sent to the ventilation layer through the board-like fiber insulation and moisture permeable waterproof sheet and discharged outside,
In addition, the waterproof material prevents moisture generated in the ventilation layer due to the moisture from entering the inside of the building through between the moisture permeable waterproof sheet and the side spacer, and the moisture in the ventilation layer Can be surely prevented from entering the building.

  In the first to third inventions, when the waterproof material is made of an adhesive tape material (fourth invention), it is only necessary to apply the adhesive tape material, the construction is easy, and the waterproof material is neatly provided. The curing period is short, and waterproofing can be performed efficiently.

  1st-3rd invention WHEREIN: The said waterproof material consists of a butyl rubber-type tape material, and the bis | screw which has attached the said side part spacer and the outer-layer heat insulating material to the structural material of a panel frame or a building is the said butyl rubber-type tape material. It is good to penetrate (5th invention).

  In this case, the same effect as that of the fourth invention can be obtained, and the water between the screw and the butyl rubber tape material is stopped by the butyl rubber tape material. Intrusion into the interior can be reliably prevented, and it can be realized with a simple structure using a butyl rubber tape material.

  Since this invention is as the above, it can prevent reliably that the water | moisture content in the ventilation layer between an exterior material and an outer-layer heat insulating material penetrate | invades in the inside of a building.
