JP, 2010-209656, A

Here, not only the structure in which a vertical gap is formed between the upper surface of the foundation and the wall frame as in the building described in Patent Document 1, but also a structure in which the wall frame is placed on the upper surface of the foundation. There are things. In this case, it is difficult to secure the thickness of the heat insulating material for connection, and it becomes difficult to improve the heat insulating performance in the connection portion between the foundation and the wall.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a building capable of enhancing the heat insulating performance in a connecting portion between a foundation and a wall.

A building according to one aspect of the present invention stands in a vertical direction and includes a foundation including an outer surface facing the outdoor side of the building and an inner surface facing the indoor side of the building, and an outer wall connected to the foundation. A panel, which is a frame set including a lower frame member placed on the upper surface of the foundation, an outer wall heat insulating material arranged on the outdoor side of the frame set, and an outer wall side of the outer wall heat insulating material. An outer wall panel including an outer wall that is arranged and supported by the framework, an outer foundation heat insulating material that is arranged on an outer surface of the foundation, and a floor material that is arranged on the indoor side of the outer wall panel. A member for supporting the floor material with respect to the foundation, having a portion placed on the upper surface of the foundation, and arranged to overlap the lower frame material in the inward and outward directions of the building. A floor supporting member, a heat insulating material interposed in a vertical gap between the outer wall heat insulating material and the outer foundation heat insulating material so as to overlap the lower frame material and the floor supporting member in the inward and outward directions. It is provided with the 1st connection heat insulator arranged and the inner heat insulator arranged on the inner surface side of the foundation so that it may overlap with the 1st connection heat insulator in the direction of the outside.

According to the above-mentioned building, it is possible to secure high heat insulation performance in the connecting portion between the foundation and the wall as follows. In this building, in order to ensure continuity of the heat insulating structure in the connection portion between the foundation and the wall, the first connecting heat insulating material is interposed in the vertical gap between the outer wall heat insulating material and the outer base heat insulating material. There is. Here, the said 1st connection heat insulating material is arrange|positioned so that it may overlap with a lower frame material and a floor support member in the inside-outside direction. Therefore, due to the interference between the lower frame member and the floor support member, it is difficult to form the first connecting heat insulating material to be thick in the inner and outer directions, and as a result, it is difficult to improve the heat insulating performance in the connecting portion between the foundation and the wall.

On the other hand, in the building of the present invention, the inner heat insulating material is arranged on the inner surface side of the foundation so as to overlap the first connecting heat insulating material in the inner and outer directions. This makes it possible to compensate for the decrease in the heat insulating performance due to the inability to form the first connecting heat insulating material thick in the inner and outer directions by disposing the inner heat insulating material. Therefore, according to the building of the present invention, it is possible to enhance the heat insulating performance in the connection portion between the foundation and the wall.

The building is a member that is arranged below the outer wall and guides the water flowing down along the outer surface of the outer wall to the outdoor side, and the first connecting heat insulating material is overlapped in the inward and outward directions. You may further provide the drainer arrange|positioned rather than the 1 connection heat insulating material at the outdoor side.

According to this configuration, it is possible to prevent the water flowing down the outer surface of the outer wall from entering the indoor side. Further, as described above, the inner heat insulating material can ensure the heat insulating property in the connecting portion between the foundation and the wall, and thus the space for disposing the draining member can be secured outside the first connecting heat insulating material.

In the above building, a ventilation path extending in the vertical direction may be provided between the outer wall and the outer wall heat insulating material. The first connection heat insulating material may be disposed closer to the indoor side than the ventilation passage so as to open a lower portion of the ventilation passage to an external space.

With this configuration, the inside of the outer wall panel can be easily ventilated. Further, as described above, the inner heat insulating material can ensure the heat insulating property in the connection portion between the foundation and the wall, so that the space for opening the lower part of the ventilation path to the external space is secured outside the first connecting heat insulating material. It will be possible.

In the building, the first connection heat insulating material may be made of a material having higher flexibility than the outer wall heat insulating material and the outer foundation heat insulating material.

According to this configuration, the first connection heat insulating material can be sandwiched and easily compressed by the outer wall heat insulating material and the outer base heat insulating material, and the heat insulating structure in the connecting portion between the outer wall heat insulating material and the outer base heat insulating material can be reduced. It becomes possible to ensure continuity more reliably.

The building includes an inner foundation heat insulating material arranged on an inner surface of the foundation, a floor heat insulating material arranged on a lower surface of the floor material, and an intervening gap between the inner foundation heat insulating material and the floor heat insulating material. The second connecting heat insulating material may be included. A part of the inner foundation heat insulating material, the floor heat insulating material, and the second connecting heat insulating material may constitute the inner heat insulating material.

According to this structure, since the foundation can be wrapped from both the inside and outside by the outer foundation heat insulating material and the inner foundation heat insulating material, the heat insulating performance of the building can be further enhanced.

In the building, the second connection heat insulating material may be made of a material having higher flexibility than the inner foundation heat insulating material and the floor heat insulating material.

According to this configuration, the weight of the floor material allows the second connection heat insulating material to be easily compressed, so that a gap can be prevented from being formed at the connection portion between the floor heat insulating material and the inner foundation heat insulating material.

The building may further include a third connecting heat insulating material interposed in a gap between the heat insulating material of the outer wall panel and the floor heat insulating material.

According to this configuration, it is possible to secure continuity of the heat insulating structure in the connecting portion between the foundation and the wall even in the indoor side portion of the building, and further improve the heat insulating performance.

As is clear from the above description, according to the present invention, it is possible to provide a building capable of enhancing the heat insulating performance in the connection portion between the foundation and the wall.
