[0002]

2. Description of the Related Art Conventionally, in a house constructed by a panel construction method, the front and back surfaces of a wall panel used for this have been integrated.

[0003]

By the way, in the case where the front and back surfaces of the panel are integrally formed as in the above-mentioned conventional house, even if the heat bridge is large and the heat insulating material is thick, it is difficult to obtain a high heat insulating panel. It was However, at present, houses tend to be highly insulated and airtight.

The present invention was developed in view of the above circumstances, and an object thereof is to provide a highly heat-insulating and highly airtight panel construction method, and a wall panel and an airtight sheet used therefor.

[0005]

In order to achieve the above object, in the present invention, a panel frame for attaching members is separated into a front surface and a back surface to form a panel, and an airtight material is provided at a joint portion of the panel. It is characterized by being attached to another component.

The panel used for this is a front and back panel connector in which panel frames for attaching members are formed separately on the front and back sides, and the panel frames are formed such that the area on the indoor side is large and the area on the outdoor side is small. It is a connection.

Further, the airtight sheet is formed by fixing airtight materials along the left and right side edges of the moisture-proof sheet.
