Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an underfloor storage provided on the floor of a building.

[0002]

BACKGROUND ART As shown in the sectional view of FIG. 2, a building foundation 1
Underfloor space 2 surrounded by (or underfloor space between upper and lower floors)
In order to make effective use of the underfloor space 2, the underfloor storage 3
Is installed and used. The underfloor storage 3 includes an underfloor storage main body 4 installed in the underfloor space 2 and a lid member 6 arranged in an opening provided in the floor 5. It is desirable that the suitable temperature of the inside 7 of the underfloor storage 3 is a relatively low temperature because foods and the like may be stored.

On the other hand, the room 8 has a floor 5 and an underfloor storage 3
Since it is in contact with the underfloor space 2 with a space between them, the underfloor space 2
Although it is easily affected by the outside air (cold air) introduced into the room, it is suitable for storing food and the like stored in the inside 7 of the underfloor storage 3, but it is not preferable in terms of controlling the room temperature in the room 8. Therefore, in order to avoid the influence of the outside air (cold air) of the underfloor space 2 on the room 8, the heat insulating material 10 is attached to the underfloor space 2 side of the floor 5, and the entire outside surface of the underfloor storage main body 4 (the underfloor space 2
The heat insulating material 9 is attached to the side).

[0004]

However, in the structure in which the heat insulating material 9 is stretched over the entire outer surface, the inside 7 of the underfloor storage main body 4 is blocked by the heat insulating material 9 from being cooled by the outside air. However, there is a problem that the temperature of the inside 7 of the underfloor storage 3 cannot be maintained at a low proper temperature due to the influence of the temperature of the room 8 side which separates the lid member 6.

It is an object of the present invention to provide a structure of an underfloor storage which is not affected by the temperature inside the room and at the same time can keep the temperature in the underfloor storage at an appropriate temperature.

[0006]

In order to achieve the above object, the present invention provides an underfloor storage provided on the floor of a building and having a lid member, and an outside of the underfloor storage provided on the floor.
A support member for supporting the, a heat insulating material stretched along the bottom surface of the building and the lid member, and the outside of the underfloor storage
Stretched near the boundary with the floor and below the support member.
And a heat insulating material . Alternatively, a plastic foam member, preferably extruded expanded polystyrene, may be used as the heat insulating material .

[0007]

In the present invention, since the lid member disposed between the room and the underfloor storage is provided with the heat insulating material, the influence of the temperature from the underfloor space to the room can be prevented, and the inside of the underfloor storage can be controlled by the room. Without being affected by the temperature inside, cooling from the underfloor space can be obtained and the inside of the underfloor storage can be maintained at an appropriate temperature. Further, when a plastic foam member is used as the heat insulating material, this material is not in the form of particles, and therefore it is easy to handle. Further, since it is lightweight, the burden of opening and closing the lid member is light. Furthermore, when the heat insulating material is provided in the vicinity of the boundary between the outside of the underfloor storage and the floor, it is possible to maintain continuity of the floor and the lid member around the underfloor storage and the heat insulating function near the underfloor storage.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment to which the structure of the underfloor storage of the present invention is applied will be described below with reference to FIG. In this embodiment, the structure of the underfloor storage described with reference to FIG. 2 is improved, and the same or corresponding components are designated by the same reference numerals, and the description thereof will be simplified or omitted.

As shown in the sectional view of FIG. 1, the floor 5 has a floor surface material 5A attached to the upper surface thereof, and a heat insulating material 10 such as glass wool is attached to the back side of the floor surface material 5A (underfloor space 2 side). Has been. The underfloor storage 3 has a main body 4 projecting from the floor 5 to the underfloor space 2, an outer frame 3A is attached to an inner edge of an opening portion of the underfloor storage 3, and a receiving portion 3B is provided inside the outer frame 3A. The foamed rubber sheet 12 as a sealing material is attached to the receiving portion 3B over the entire circumference.

The lid member 6 is fitted to the receiving portion 3B to seal the inside 7 of the underfloor storage 3, and like the floor 5, the floor surface material 5A is attached to the upper surface and the back surface is heat-insulated. As a material, a plastic foam member (for example, extruded polystyrene foam) 11 is attached to the heat insulating material 10 of the floor 5 with substantially the same thickness. The outer edge of the lid member 6 covers the entire circumference of the lid frame 6A.
The lid frame 6A comes into close contact with the foamed rubber sheet 12 when fitted into the receiving portion 3B, so that the airtightness between the underfloor space 2 and the room 8 is maintained. The foamed rubber sheet 12 may be attached to the lower surface of the lid frame 6A. still,
A rotary handle 13 is provided on the upper surface of the lid member 6.

According to the above embodiment, since the plastic foam member 11 having a heat insulating function is attached to the back side of the lid member 6, the influence of the temperature from the underfloor space 2 to the room 8 can be prevented and the underfloor storage can be performed. The inside 7 of the cabinet 3 is not affected by the temperature of the room 8 side, and the underfloor space 2 is cooled by the cool air, so that the inside 7 of the underfloor cabinet 3 can be maintained at an appropriate temperature.

Further, since the plastic foam member 11 is used as the heat insulating material attached to the back side of the lid member 6, and this material is not in the shape of particles, it is easy to handle when attaching to the lid member 6 or the like. Further, since it is lightweight, the lid member 6
The burden of opening and closing work is also light. Further, since the heat insulating material 9 is provided at the boundary between the underfloor storage 3 and the heat insulating material 10 on the floor 5, the continuity of the heat insulating function between the floor 5 around the underfloor storage 3 and the vicinity of the underfloor storage 3 is provided. Can also keep enough.

Although the present invention has been described with reference to the preferred embodiment, the present invention is not limited to this embodiment, and various improvements and design changes can be made without departing from the scope of the present invention. It is possible. In the above-mentioned embodiment, a plastic foam member is described as an example of the heat insulating material 11 attached to the lid member 6, but other heat insulating materials such as glass wool, rock wool and asbestos may be used.

[0014]

According to the structure of the underfloor storage according to the present invention, the temperature in the underfloor storage can be maintained at an appropriate temperature while being unaffected by the temperature inside the room.
