Abstract

(57) [Summary] [Purpose] A floor panel that can improve the heat insulation and airtightness around the outer wall and does not require special on-site construction such as heat insulation. [Structure] The floor panel 1 is provided with an elastic member 4 made of a soft material having heat insulation and airtightness along a side a of the panel facing the outer wall. For the heat insulating material 4, for example, soft urethane foam or the like is used. The floor panel 1 has a basic structure in which, for example, a joist 2 and a floor plate 3 are stretched on the joist 2.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a floor panel installed adjacent to an outer wall in a house or other building.

[0002]

[Prior art]

 Conventionally, in a building such as a house, a floor panel 51 and an outer wall panel 53 shown in FIG. That is, the outer wall panel 53 is installed on the cloth foundation 52 via the base 54, and the joists 56 of the floor panel 51 are installed on the joist receiver 55 provided on the indoor side of the base 54. The outer wall panel 53 is provided with a heat insulating material 57 such as glass wool.

[0003]

[Problems to be solved by the device]

 However, with this conventional structure, a gap S is formed between the outer wall panel 53 and the floor panel 51 as shown by a meshed portion, and the gap S reduces the heat insulating property and airtightness of the entire building. There was a point. Especially in houses in cold regions, it is desired to improve the heat insulation and airtightness around the outer wall.

An object of the present invention is to provide a floor panel that can improve heat insulation and airtightness around an outer wall and does not require special on-site construction such as heat insulation treatment.

[0005]

[Means for Solving the Problems]

 The floor panel of this invention is provided with an elastic material made of a soft material having heat insulation and airtightness along the side of the panel facing the outer wall.

[0006]

[Action]

 When this floor panel is installed along the outer wall, the gap between the floor panel and the outer wall is filled with elastic material. Since this elastic material is a material having heat insulation and airtightness, heat insulation and airtightness around the outer wall are improved. Since the elastic material is provided on the floor panel in advance, no special on-site construction for heat insulation treatment is required. In addition, since a soft elastic material is used, even if there is some variation in the distance to the outer wall, it is possible to eliminate the gap reliably.

【Example】

 An embodiment of the present invention will be described with reference to FIGS. In this floor panel 1, a plurality of parallel wooden joists 2 are covered with a floor board 3 made of waterproof plywood or the like, and elastic members 4 are provided along the entire length of the side a facing the outer wall. It is a thing. The elastic material 4 is adhered with an adhesive across the frame material 5 provided between the joists 2 on the side a and the end surface of the floorboard 3. The frame member 5 does not necessarily have to be provided. The elastic material 4 is made of a soft material having heat insulation and airtightness, and for example, soft urethane foam or the like is used.

FIG. 2 is a plan view showing the first floor of the entire building using the floor panel 1. The floor panel 1 and a large number of other floor panels 11 to 16 are laid on a cloth foundation 21 through a joist receiver (a portion indicated by diagonal lines in the figure) 22. In the figure, each rectangular portion with a thin diagonal line indicates one floor panel 11-16. Of these floor panels 11 to 16, each of the floor panels 11 to 15 along the outer wall has the elastic material 4 attached along the side of the panel facing the outer wall, like the floor panel 1.

FIG. 3 is a vertical cross-sectional view showing the accommodation of the floor panel 1 and the outer wall panel 23 in the AA cross section of FIG. The outer wall panel 23 has a panel frame 24 to which an exterior surface material 25 is attached, and a heat insulating material such as glass wool (not shown) is provided on the exterior surface material 25 side. It is installed via a shaped steel base (not shown). A heat insulating material 26 such as glass wool is filled between the lower side of the panel frame 24 and the cloth foundation 21 on site.

The floor panel 1 has its end provided with the elastic member 4 placed on the joist receiver 22 on the cloth foundation 21 and fixed by a fastener 27 such as a wood screw. The gap between the end surface of the floor panel 1 and the indoor surface 23a of the outer wall panel 23 is filled with the elastic material 4. The elastic member 4 is provided, for example, with a thickness of about 50 mm, but when it comes into contact with the outer wall panel 23, it is compressed to, for example, about 30 mm.

FIG. 4 is a vertical cross-sectional view showing a section of the floor panel 11 and the outer wall panel 23, in which the side b along the longitudinal direction is adjacent to the outer wall, taken along the line BB in FIG. Also in this part, the floor panel 11 is installed adjacent to the outer wall panel 23, so that the elastic material 4 on the side b is compressed and fills the gap between the outer wall panel 23 and the back surface 23a.

As described above, according to the floor panels 1 and 11, the gap between the outer wall panel 23 and the outer wall panel 23 is filled with the elastic material 4, and the heat insulation and airtightness of the elastic material 4 cause heat insulation and airtightness around the outer wall. The property is improved. Therefore, the heat insulation and airtightness of the entire building are improved. Since the elastic member 4 is provided on the floor panels 1 and 11 in advance, the heat insulating treatment is completed only by installing the floor panels 1 and 11, and no special on-site construction for heat insulating treatment is required. Further, since the soft elastic material 4 such as soft urethane foam is used, even if there is some variation in the distance to the outer wall panel 23, the gap can be surely eliminated.

In the above-mentioned embodiment, the soft urethane foam which is a single material is used as the elastic material 4. However, an elastic material in which the outer surface of a heat insulating material such as soft urethane foam is covered with a resin coating or the like may be used.

[0014]

[Effect of device]

 Since the floor panel of this invention is provided with an elastic material made of a soft material having heat insulation and airtightness along the side of the panel facing the outer wall, the gap between the outer wall and the outer wall is filled, and the heat insulation around the outer wall is reduced. It is possible to improve airtightness and airtightness, and there is no need for special on-site construction.
