<2.2. Floor panels and decorative boards>
The floor panels 25 to 28 are constructed of architectural structural bodies. Specifically, the floor panels 25 to 28 are constructed of wooden construction panels used in the so-called wood panel bonding method. Therefore, the floor panels 25 to 27 have a structural strength comparable to that of a structural frame that is a component of the building in which the unit furniture 10 is installed.

Architectural panels are vertical and horizontal frame members assembled into a rectangular frame, one or more auxiliary frame members are assembled vertically or horizontally or vertically and horizontally inside the rectangular frame, and one or more face members are assembled into this rectangular frame. A unit with a hollow structure that is attached to one side of a rectangular frame, and one or more face materials are attached to the other side of the rectangular frame as necessary. The hollow space is usually filled with a heat insulating material such as glass wool or rock wool.

To explain the floor panel 25 more specifically, the floor panel 25 includes a pair of vertical frame members 25a, a pair of horizontal frame members 25b, two auxiliary frame members 25c, and two face members 25d. The vertical stile members 25a and the horizontal stile members 25b are assembled into a rectangular frame, with the vertical stile members 25a forming the long sides of the rectangular frame, and the horizontal stile members 25b forming the short sides of the rectangular frame. The auxiliary frame member 25c is assembled inside the rectangular frame so as to be parallel to the vertical frame member 25a. Two rectangular face materials 25d are overlapped and pasted on one side of the rectangular frame.

Therefore, the floor panel 25 has a rectangular plate shape, one side of the floor panel 25 is formed flat by the facing material 25d, and the other side of the floor panel 25 is surrounded by the frame materials 25a, 25b and the auxiliary beam material 25c. It is formed in a concave shape in the closed area. Hereinafter, of both surfaces of the floor panel 25, the surface formed flat by the facing material 25d will be referred to as a flat surface, and the surface formed in a concave shape will be referred to as a concave surface.

Floor panels 26 to 28 are also provided in the same way as floor panel 25. The floor panels 25 to 27 are shaped like rectangular plates in a narrow sense. The sizes of the floor panels 26 and 27 are equal to each other, and the length of the long side of the floor panel 25 is equal to twice the length of the short side of the floor panels 26 and 27. A pair of opposite sides of the floor panel 28 are longer than the short sides of the floor panels 26 and 27 and shorter than the long sides of the floor panel 25. The floor panel 28 is formed into a square plate shape or a rectangular plate shape in a narrow sense in which the long side and the short side are approximately equal. The thicknesses of the floor panels 25-28 are equal to each other.

As shown in FIG. 5, the rectangular decorative boards 125-128 have the same size as the floor panels 25-28, respectively. The decorative boards 125-128 are fixed to the floor panels 25-28 with screws. At least one of the screws that fastens the decorative board 125 to the floor panel 25 is driven into a position overlapping the upper ends of the leg units 21 and 23 that support the floor panel 25. At least one of the screws that fastens the decorative board 126 to the floor panel 26 is driven into a position overlapping the upper ends of the leg units 21 and 22 that support the floor panel 26. At least one of the screws for fixing the decorative board 127 to the floor panel 27 is driven into a position overlapping the upper ends of the leg units 22, 23, 24 that support the floor panel 27. At least one of the screws that fastens the decorative board 128 to the floor panel 28 is driven into a position overlapping the upper ends of the leg units 22 and 24 that support the floor panel 28.

<2.2.1. Floor panel orientation and layout>
These floor panels 25-28 are attached to the upper ends of the leg units 21-24 with their concave surfaces facing upward and their flat surfaces facing downward. The flat surfaces of these floor panels 25 to 28 are flush with each other.

By attaching the floor panels 25 to 28 to the upper ends of the leg units 21 to 24 so as to spread them out, a space 97 below the floor panels 25 to 28 and a space 98 above the floor panels 25 to 28 are partitioned by the floor panels 25 to 28. The upper space 98 can be used as one room with sufficient ceiling height for a living room. The lower space 97 is used as a low-ceiling storage space that can be accessed from room 1. The entrance to the lower space 97 is in the area between the left front gear unit 21 and the right front gear unit 22. The ceiling height of the lower space 97 is 0.8 to 1.4 m. This ceiling height of 0.8 m to 1.4 m is a height range to ensure a minimum height at which a person can enter the space 97 below and work by bending down. However, the ceiling height of the lower space 97 is not limited to this, and the ceiling height may be changed arbitrarily. That is, the ceiling height of the lower space 97 is set to a dimension that allows a person to walk and work in a standing position, and the ceiling height of the upper space 98 is set to a size that allows a person to walk and work while bent at the waist. The space 98 above may be used as a loft. In addition, for example, if the ceiling height of room 1 is high because room 1 is open to the upper floor, the ceiling heights of both the upper and lower spaces 97 and 98 should be set to a size that allows people to walk and work in a standing position. May be set. Conversely, the ceiling heights of both the upper and lower spaces 97 and 98 may be set to dimensions that allow a person to walk and work while bending down. In short, since the unit furniture 10 is just furniture, the ceiling heights of the upper and lower spaces 97 and 98 are not particularly limited and can be set arbitrarily.

Both short sides of the floor panel 26 are aligned with both short sides of the floor panel 27, and the end faces of the short sides of the floor panel 26 are flush with the end faces of the short sides of the floor panel 27, respectively. The end faces of the long sides of the floor panel 26 are abutted against the end faces of the long sides of the floor panel 27, and these end faces are joined together by a joining material such as screws. The other long sides of the floor panels 26 and 27 are aligned with the pair of short sides of the floor panel 25, and the end faces of these long sides are flush with the end faces of the pair of short sides of the floor panel 25, respectively. The short side end faces of the floor panels 26, 27 are abutted against the long side end faces of the floor panel 25, and are joined by a joining material such as screws. The end face of the other short side of the floor panel 27 is abutted against the end face of one side of the floor panel 28, and is joined by a joining material such as screws. Of both long sides of the floor panel 27, the end face of the long side that is not in contact with the floor panel 26 is aligned with the end face of the other side of the floor panel 28, and these end faces are flush. The floor panel 28 protrudes slightly in front of the abutting surfaces of the floor panels 26 and 28.

The floor panel 25 is laid out so that both long sides of the floor panel 25 face leftward and rightward, respectively, and both short sides of the floor panel 25 face forward and backward, respectively. Both long sides of the floor panels 26, 27 are oriented leftward and rightward, respectively, and long sides of the floor panels 26, 27 are oriented forward and backward, respectively, and these floor panels 26, 27 are arranged in parallel. Floor panels 26 and 27 are arranged to the right of floor panel 25, floor panel 27 is arranged behind floor panel 26, and floor panel 28 is arranged to the right of floor panel 27. The floor panels 25-28 arranged in this manner are supported by leg units 21-24. In particular, at least three of the four corners of the floor panels 25-28 are supported by resting on any of the leg units 21-24.

<4. Advantageous technical effects>
(1) Since the concave surfaces of the floor panels 25 to 28 are facing upward, it is difficult to join the floor panels 25 to 28 next to each other, and to join the floor panels 25 to 28 and the leg units 21 to 24. During the work, the worker can work in a crouched position on the floor panels 25 to 28, making the joining work easy.

(2) Since the decorative board 125 is sandwiched between the floor panel 25 and the leg units 21 and 23, the decorative board 125 will not separate from the floor panel 25 even if the strength with which the decorative board 125 is attached to the floor panel 25 is weak. . Therefore, the number of screws for fixing the decorative board 125 to the floor panel 25 can be reduced, and the appearance of the decorative board 125 is good. The same applies to the decorative boards 126 to 128.

(3) Before installing the floor panels 25 to 28 on the upper ends of the leg units 21 to 24, the decorative boards 125 to 128 are attached to the floor panels 25 to 28, respectively. The direction of ~28 is free. Therefore, at the installation site or factory, the worker places the floor panels 25 to 28 so that the concave surfaces of the floor panels 25 to 28 are facing upward, and in a natural forward-leaning posture, installs the decorative panels 125 to 128. The decorative boards 125 to 128 can be screwed onto the floor panels 25 to 28 from above. Therefore, the work load is low and work safety is high. Furthermore, there is a very low possibility that wood chips generated from the decorative boards 125 to 128 and the floor panels 25 to 28 will come into contact with the worker's face.

(4) At least one of the screws that fastens the decorative board 125 to the floor panel 25 is driven into a position overlapping the upper ends of the leg units 21 and 23 that support the floor panel 25. Therefore, such screws are hidden by the leg units 21 and 23. Therefore, the decorative board 125 has a good design. The same applies to the decorative boards 126 to 128.

(5) Since the floor panels 26 and 27 are supported at three points, when attaching the floor panels 25 to 27 to the upper ends of the leg units 21 to 24, prepare a material separately from the leg units 21 to 24 and use this material. There is no need to support the floor panels 25 to 27 from below. Therefore, the space 97 under the floor panels 25 to 27 can be widened.

(6) Since the rear left corner of the floor panel 26 and the front left corner of the floor panel 27 are floating in the air, the space 97 under the floor panels 25 to 27 can be widened.

(7) Since the face material 35 is attached to the floor panels 26 and 27 with screws, the bonding strength between the floor panels 26 and 27 is increased. Since the face material 36 is attached to the floor panels 25 and 26 with screws, the bonding strength between the floor panels 25 and 26 is increased. Since the face material 37 is attached to the floor panels 25, 27 with screws, the bonding strength between the floor panels 25, 27 is increased. Therefore, even if the left rear corner of the floor panel 26 and the left front corner of the floor panel 27 are floating in the air, the sinking of these corners is reliably suppressed.
