## Abstract

A heat-insulating waterproof structure includes a heat-insulating waterproof member arranged on a building body. The building body includes a foundation and an exterior wall body arranged on the foundation. The exterior wall body includes a metal fitting arranged on the foundation, a column set on the foundation with the metal fitting member located in between, and a backing arranged on the column. The heat-insulating waterproof member includes a heat-insulating member and a waterproof member integrated with the heat-insulating member. The heat-insulating waterproof member is located at an outer side of the exterior wall body along the exterior wall body at a height where the metal fitting is located.

## Claims

### Claim 1

A heat-insulating waterproof structure of a building, the heat-insulating waterproof structure comprising:
a heat-insulating waterproof member arranged on a building body, wherein:
the building body includes a foundation and an exterior wall body arranged on the foundation,
the exterior wall body includes a metal fitting arranged on the foundation, a column set on the metal fitting, the metal fitting located between the foundation and the column, and a backing arranged on the column,
the heat-insulating waterproof member includes a heat-insulating member and a waterproof member integrated with the heat-insulating member, the heat-insulating waterproof member being located at an outer side of the exterior wall body along the exterior wall body at a height where the metal fitting is located,
the building body further includes:
a flashing member arranged between the foundation and the backing in a height direction; and
a waterproof sheet arranged on an outer surface of the backing,
the heat-insulating waterproof member is arranged below a lower surface of the backing,
the flashing member is fixed to an outer surface of the heat-insulating waterproof member, and
the waterproof sheet includes a lower end portion that covers an upper end portion of the flashing member.

### Claim 2 (depends on 1)

The heat-insulating waterproof structure according to claim 1, wherein the waterproof member is located closer to the foundation than the heat-insulating member is.

### Claim 3 (depends on 1)

The heat-insulating waterproof structure according to claim 1, wherein:
the heat-insulating waterproof member includes an auxiliary member, and
the auxiliary member includes a first portion that is attached to the heat-insulating member and the waterproof member and a second portion that is arranged along the heat-insulating member.

### Claim 4 (depends on 1)

The heat-insulating waterproof structure according to claim 1, wherein:
the heat-insulating waterproof member further includes a fixing member that fixes the lower end portion of the waterproof sheet to the upper end portion of the flashing member, and
the fixing member includes a bonding portion bonded to the lower end portion of the waterproof sheet, the fixing member being integrated with the waterproof member and the heat-insulating member.

### Claim 5

A method for installing a heat-insulating waterproof structure that is arranged on a building body, the building body including a foundation and an exterior wall body arranged on the foundation, the exterior wall body including a metal fitting arranged on the foundation, a column set on the metal fitting, the metal fitting located between the foundation and the column, and a backing arranged on the column, the method comprising:
providing the heat-insulating waterproof structure with a heat-insulating waterproof member, wherein:
the heat-insulating waterproof member includes a heat-insulating member and a waterproof member integrated with the heat-insulating member,
the providing the heat-insulating waterproof structure with the heat-insulating waterproof member includes arranging the heat-insulating waterproof member between the foundation and a lower surface of the backing of the exterior wall body so that the waterproof member contacts the foundation without forming a gap between the heat-insulating member and the foundation,
the building body further includes:
a flashing member arranged between the foundation and the backing in a height direction; and
a waterproof sheet arranged on an outer surface of the backing,
the heat-insulating waterproof member is arranged below a lower surface of the backing,
the flashing member is fixed to an outer surface of the heat-insulating waterproof member, and
the waterproof sheet includes a lower end portion that covers an upper end portion of the flashing member.
