  2. Description of the Related Art Conventionally, a deck material that is provided in parallel with a balconi of a building and constitutes a floor surface, and an outdoor floor structure using the deck material are known (see, for example, Patent Document 1). In this outdoor floor structure, a connecting member is disposed at a joint portion between adjacent deck members, and the deck member and the connecting member are connected by male-female engagement.

JP-A-11-229486 (FIGS. 3 and 4)

  However, in the conventional outdoor floor structure (deck floor structure) shown in Patent Document 1, adjacent deck materials are arranged close to each other, and the lighting performance for the lower side is not considered.

  The objective of this invention is providing the deck floor structure and building which can ensure the lighting property with respect to the downward direction of a floor surface.

In order to achieve this object, the deck floor structure and building of the present invention have the following configuration. That is, with reference to the drawings, the deck floor structure of the present invention is a deck floor structure installed in a building having an upper floor space 32 and a lower floor space 31, and the floor of the upper floor space 32. A plurality of deck materials 11 are provided at substantially the same height as the surface and at a position outside the daylighting target portion S1 in the lower floor space 31, and these deck materials 11 are substantially horizontal upper surface portions 111. And an inclined side surface portion 112 on the side of the light extraction target portion inclined downward toward the light extraction target portion S1, a bottom surface portion 113 substantially parallel to the upper surface portion 111, and substantially parallel to the inclined side surface portion 112. And the second side surface portion 114 is formed in a substantially parallelogram shape in cross section, and the upper surface portions 111 of the deck materials 11 adjacent to each other are installed via a gap Wgap1 equal to or greater than the width dimension W of the upper surface portion 111 , Adjacent deck material 11 An extension line extending downward from the edge of the upper surface portion 111 of one of the deck materials 11 is downward from the edge of the bottom surface portion 113 of the other deck material 11 on the one deck material 11 side. It is arranged to form an extended extension line and a horizontal gap Wgap2 .
Here, the height position of the deck material 11 is substantially the same as the floor surface of the upper floor space 32. The height position of the deck material 11 is set to such an extent that the deck floor structure can be easily moved in and out of the upper floor space 32. It means being.

According to such a configuration, since the upper surface portions of the deck material are installed with an interval and the inclined side surface portion is inclined toward the daylighting target portion, the daylighting target portion is interposed with the interval portion between the deck materials. Sunlight can be passed toward the light source, and the daylighting property to the daylighting target part can be secured.
In addition, when standing on the deck floor structure and looking downward, since the inclined side surface appears to overlap the space between the top surfaces, the gap that is actually visible is smaller than the space between the top surfaces. It gives you a sense of security.
Furthermore, the upper floor space located above the daylighting target portion is blocked by the inclined side surface portion so that the lower floor space cannot be seen, and the daylighting target portion can also be seen from the lower floor space on the opposite side through the deck floor structure. The upper floor space cannot be seen because it is blocked by the inclined side surface. Therefore, the privacy between the upper floor space and the lower floor space can be protected.
Moreover, since the cross-section of the deck material is formed in a substantially parallelogram shape, the appearance when viewed from below is the same as the appearance from above, and the design is good.
When standing on the balconi, the inclined side surface appears to overlap the gap on the upper surface, so the gap that is actually visible is smaller than the gap on the upper surface, giving you a sense of security. It is done.

  In the deck floor structure of the present invention, in the deck material 11B, the upper surface portion 111, the inclined side surface portion 112, the bottom surface portion 113, and the second side surface portion 114 each cover the outer periphery of an aluminum profile with resin. A hollow two-layer structure is preferable.
  According to such a configuration, since the deck material having a substantially parallelogram cross-section is formed in a hollow shape, the weight of the deck material can be reduced, and the weight of the deck floor structure can be reduced.

In the deck floor structure of the present invention, the resin covering the outer periphery of the aluminum profile is preferably a resin containing wood powder .
According to such a configuration, since the deck material is formed of a resin containing wood powder, it has excellent weather resistance and corrosion resistance, and can have an excellent appearance by obtaining a wood atmosphere.

In the deck floor structure of the present invention, the deck material 11D includes a transparent resin member 14 having a substantially right-angled triangle cross section, one side of the triangle being in contact with the inclined side surface portion 112, and the other side being the deck material 11D. The deck material having a substantially trapezoidal cross section is integrally attached so as to be continuous with the surface of the upper surface portion 111, and the deck material having a substantially trapezoidal cross section has a gap Wgap2 (Wgap3) between the deck material having the substantially trapezoidal cross section adjacent thereto. It is preferable that a plurality of them are arranged side by side .
According to such a configuration, since the resin member has translucency, the gap between the deck materials is reduced by providing the resin member between the adjacent deck materials while ensuring the daylighting property. Is improved. For example, by attaching a resin member having a triangular cross section to the inclined side surface portion of the deck material and providing a slight gap between the upper surface portion of the deck material adjacent to the inclined side surface portion and the resin member, the drainage property is also improved. Can be secured.

The building of the present invention includes the deck floor structure.
According to such a configuration, by providing the deck floor structure, it is possible to ensure the daylighting property of the portion adjacent to the deck floor structure in the lower floor space. Further, it is possible to protect the privacy between the two parts arranged so as to sandwich the deck floor structure in the upper floor space and the lower floor space. Therefore, a portion adjacent to the deck floor structure in the upper floor space and the lower floor space can be a comfortable space.
