The base material 1 according to the present invention includes, for example, a first plate material 2 on the lower side in FIG. 1 and a second plate material 3 on the upper side. A partition member 4 is interposed in a lattice shape between the two. That is, on the upper surface of the first plate material 2 made of, for example, a wooden board or the like, a partition portion 4 made of vertical bars 5 and horizontal bars 6 made of wood or synthetic resin assembled in a lattice shape, or punched or formed is fixed. At the same time,
A second plate material 3 made of plywood or the like is fixed to the upper surface of each partition member 4 to form a plate-shaped rectangular member. Therefore, this base material 1 has a plurality of mutually independent voids 7 formed by the partition member 4. In the illustrated embodiment, a vertical bar 5 is provided along the outer edge in the longitudinal direction, and a horizontal bar 6 is provided along the outer edge in the transverse direction, so that an independent gap 7 is also formed at the peripheral edge. , inward from each outer edge t
A vertical bar 5 and a horizontal bar 6 are provided to open a gap 7 located at the peripheral edge, and when the base material 1 is connected, the vertical bar 5 and the horizontal bar 6 of the adjacent base material 1 are used to prevent other base materials from forming. Alternatively, either a vertical bar 5 or a horizontal bar 6 may be provided at the outer edge in the longitudinal direction or the outer edge in the transverse direction, so that the outer edge in the longitudinal direction The void 7 located at the outer edge in the horizontal direction may be closed, but the void 7 located at the outer edge in the horizontal direction may be left open, or the void 7 located at the outer edge in the vertical direction may be opened, but the void 7 located at the outer edge in the horizontal direction may be left open. may be occluded.

Then, the width d of the gap 7 is set between the outside of the first plate material 2 and the width d of the gap 7.
When there is a temperature difference between the outside of the plate material 3 and the outside of the plate material 3, it is preferable that the inside air has a temperature of about 5 to f5 mm so that convection due to turbulence, vortex, etc. does not occur based on the -1- temperature difference.

Further, each of the voids 7 may be filled with a heat-insulating and sound-absorbing material such as glass wool.

Next, a case where the base material 1 having the above structure is applied to the base material 1 of a roof will be described.

The roof board 8 is a roof board for horizontal roofing which has a downward facing engagement part 9 on the upper edge and a downward facing engaging part 10 on the lower edge, and is a horizontal roofing board having a downward facing engagement part 9 on the upper edge and a downward facing engagement part 10 on the lower edge. A long eave hardware 13 is fitted in a series along a favorable direction at the lower end, and a ridgepole 14 is provided at one end of the slope of each of the rafters 12. Then, the base material 1 according to the present invention is laid on the upper surface of each of the rafters 12 without any gaps in the roof inclination force direction and the beam direction.

Once the base material 1 is laid on the rafters 12, a roofing board 8 is covered. In the illustrated embodiment, a roofing 15 is interposed between the roofing board 8 and the base material 1, and the roofing board 8 is placed on top of the roofing 15. are being installed. To lay the roof shingle 8, the downward locking portion 10 of the roof shingle 8 located at the eaves is locked to the locking piece 13' of the eaves edge hardware 13, and the upward retaining portion 9 is secured using a hanger (not shown) or the like. It is fastened to the rafter 1z, and the downward locking part 10 of the roof board 8 adjacent to the line side is locked to the upward locking part 9 of the roof board 8 located on the eaves side where it is fixed, and the roof board 8 is sequentially moved toward the ridge. After the roof is finished, the upper edge of the roof board 8 located at the ridge portion is fixed to the ridgepole J4. Then, a cover material 17 having a space 16 inside is applied to the purlin 14.

The cover material 17 is a long material bent into a chevron shape, for example, and has a downward hanging piece 18 in the longitudinal direction.
has been established.

According to the roof on which the base material 1 as described above is laid, a large number of independent voids 7 formed in each base material 1 exist along the roof surface. Even if the air in each of the gaps 7 does not flow with each other and there is a large temperature difference between the outside of the first plate 2 and the outside of the second plate 3, the first plate 2 and the second plate 3 Since the width d of the gap 7 between the two is set to such an extent that convection does not occur, the air within the gap 7 does not cause convection. Therefore, there is no heat exchange effect in each gap 7, and the heat insulation effect is improved. Furthermore, since the sealed void 7 has sound insulation and sound absorption effects, it also acts as a soundproofing material.

FIG. 4 shows a case where the base material 1 according to the present invention is used as an exterior wall material of a building. In this case, each base material 1 is fixed to a frame such as a beam 20 or a foundation 21, and the base material 1 is attached to the soffit. A soffit 22 is provided. Further, both pressers 23 are provided at the lower end of the base material l located at the base 21 portion. In addition, the illustrated double presser foot 23 is the lower edge? 3' is bent inward to face the foundation 24. Then, external finishing is performed by applying mortar 25 to the outer surface of the base material l.

According to the outer wall configured as described above, since there are many independent voids 7 along the wall surface, there is no heat exchange effect between each void 7, and there is no temperature difference between the outdoor side and the indoor side. Even if the gap 7 is large, the width d of the gap 7 is formed to such an extent that no convection occurs, so no convection accompanied by heat exchange occurs between the first plate material 2 and the second plate material 3, resulting in insulation. Improves effectiveness.

Further, the base material 1 has a double structure of the first plate material 2 and the second plate material 3, and has a plurality of independent gaps 7 between them, so that the soundproofing effect is improved.

In the partition 26 configured as described above, a plurality of independent voids 7 exist in the base material l, and even if there is a temperature difference between the outer surface of the first plate material 2 and the outer surface of the second plate material 3, First plate material 2
Since there is no heat exchange between the second plate material 3 and the second plate material 3, the heat insulation effect is improved, air conditioning and heating are effective, and energy saving is possible. Furthermore, this base material 1 provides effects such as improved soundproofing, making it impossible to hear sounds from neighboring rooms.

FIG. 6 shows another embodiment of the present invention, in which the positions of the outer edges of the first plate 2 and the second plate 3 are shifted. That is, as shown in FIG. 6, for example, the upper edge 3a of the second plate material 3
extends above the upper edge 2a of the first plate 2, the lower edge 3b of the second plate 3 is positioned above the lower edge 2b of the first plate 2, and the left side of the second plate 3 Edge 3C first

is set to such an extent that convection does not occur within the gap 7 when there is a temperature difference between the outside of the first plate 2 and the outside of the second plate 3.

According to the base material 1 having such a configuration, it is possible to connect the - base material 1 to each outer edge of the adjacent base material 1 at a position facing the plate material of the other base material 1. Positioning and connection with the material 1 become easier, improving work efficiency. Also, in this base material 1, the air in the void 7 does not convect due to the temperature difference outside, so there is no heat exchange via the internal air. Even if there is a temperature difference between the outside of the plate 3 and the outside, there is no heat exchange effect via the air in the void 7, and the heat insulation effect is improved.

It should be noted that the symbols not explained in this embodiment have the same configuration as the same symbols in the above-described embodiment, so the explanation will be omitted.

The partition member 4 may have a grid shape consisting of horizontal bars 6 and vertical bars 5 as shown in FIGS. 1 and 6, or may have a mesh shape in which inclined bars intersect, as shown in FIG. 7, for example. Alternatively, as shown in FIG. 8, the horizontal bars 6' may have the same position every other row, or may have a hexagonal shape with continuous hexagonal gaps, or may have other shapes. The gaps 7 located at the periphery may be open or closed, and closed gaps 7 and open gaps 7 may exist alternately. It is sufficient if the gap 7 is closed when the material 1 is laid.

Although the present invention has been described above with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments described above, and can be implemented as appropriate unless the configurations described in the claims are changed.

<Effects of the Invention> In short, the present invention forms a plurality of independent gaps between the first plate material and the second plate material by interposing the partition member between the first plate material and the second plate material. Since no heat exchange action occurs through the air, the heat insulation effect is improved. Further, the base material has a double structure of the first plate material and the second plate material, and has a plurality of mutually independent gaps between the two plate materials, so that the soundproofing effect is improved.
