1 is a perspective view showing a roof structure 1 according to a first technical reference example , FIG. 2 is a side view showing a field member 20 and a moisture-permeable roofing 30, and FIG. 3 is a perspective view showing a combination of the field member 20 and FIG. FIG. 3 is a perspective view showing a combination of moisture permeable roofing 30. In FIG. 1, F and G indicate the flow of ventilation.

  As shown in FIGS. 1 and 2, the roof structure 1 includes a plurality of rafters 10, a field member 20 passed over the rafters 10, moisture permeability and a constant distance on the field member 20, and Moisture permeable roofing (sheet) 30 formed of a waterproof material, a plurality of crosspieces 40 provided on the moisture permeable roofing 30 as support members, and provided on the moisture permeable roofing 30 near the edge of the roof. And a plurality of roof tiles 50 provided on the pier 40 and the nose pier 41 and fixed by, for example, nails or the like.

  The field member 20 includes a plurality of lower plates (lower-stage side plate group) 21 formed of a narrow plate material and provided in a direction orthogonal to the rafter 10 at regular intervals, and a lower plate 21 formed of a narrow plate material in a direction orthogonal to the lower plate 21 at regular intervals. The upper plate (upper side plate material group) 22 provided is combined to form a lattice. Further, for example, when the size of the field member 20 is insufficient with respect to the size of the roof (size or shape that cannot be handled by one field member 20 or the like), as shown in FIG. A plurality of field members 20 having sleeve portions 23 at their ends are used. At this time, the sleeve portions 23 of the adjacent field members 20 are brought into contact with each other, and the joining member 24 is installed on the upper portion or the lower portion of the contact portion of the sleeve portion 23 and fixed by, for example, nailing, thereby joining the field members 20. Even when a plurality of sheets are used, the base plate 20 having no sleeve 23 may be used.

  When the field member 20 is coupled in this way, the size of the moisture permeable roofing 30 provided on the field member 20 is slightly larger than the field member 20 to be combined, as shown in FIG. By stacking the moisture permeable roofing 30 on the sleeve 23), it is possible to combine the field members 20 without leaking rainwater or the like. When the moisture-permeable roofing 30 is stacked, the moisture-permeable roofing 30 on the side where the height difference of the moisture-permeable roofing 30 is high is stacked on the upper side. Here, the moisture-permeable roofing 30 may be a single-cloth-shaped moisture-permeable roofing 30 having the same area as the roof, without combining these moisture-permeable roofings 30.

  The pier 40 has a ventilation plate 42 between the moisture-permeable roofing 30 and the pier 40 so that a space is provided on the lower surface of the pier 40 to allow ventilation. In addition, the nose bridge 41 has a hollow body 43 in order to allow ventilation and drainage of the space between the roof tile 50 and the moisture-permeable roofing 30 to the outside.

  In the roof structure 1 configured as described above, the space between the moisture permeable roofing 30 and the roof tile 50 can be ventilated on the upper surface of the moisture permeable roofing 30 by the ventilation plate 42 and the hollow body 43 as indicated by an arrow F. It has become. Further, even when rainwater or the like enters from the roof tile 50, rainwater or the like does not permeate below the field member 20 due to the moisture permeable roofing 30, and the rainwater or the like is discharged to the outside by the ventilation plate 42 and the hollow body 43. The

  In the field member 20, ventilation is possible as indicated by an arrow G due to the space formed by the upper plate 22 and the lower plate 21. Further, moisture or the like in the space of the field member 20 is discharged to the outside by ventilation, or is transmitted to the space between the roof tile 50 and the moisture-permeable roofing 30 by the moisture-permeable roofing 30 on the upper surface of the field member 20 and then to the outside. And vented. This ventilation prevents moisture from spreading in the space around the field member 20, so that wood and the like are less likely to rot and durability can be improved.

  Furthermore, since it becomes possible to match | combine with the width of a roof by combining the multiple field members 20, it has the versatility which can respond to the roof of various shapes and widths. For example, since the field member 20 of several types is manufactured in a factory etc. and this field member 20 only needs to be combined (construction) according to the size of the roof on the site, the construction process can be reduced and the construction time can be reduced. In addition, the construction cost can be reduced.

As described above, according to the roof structure 1 according to the reference example of the present technology , it is possible to perform ventilation by using the field member 20 formed in a lattice shape with the upper plate 22 and the lower plate 21 as the field plate. Therefore, the roof structure 1 having a simple structure and sufficient ventilation efficiency of the house can be formed. That is, the moisture transmission resistance can be greatly reduced as compared with the case where the plywood is used as the base plate, and the radiant heat of the roof tile can be discharged without being stored.

FIG. 5 is a side view showing a field member 20A of the roof structure 1A according to the first modification of the above-described technical reference example . 5, the same functional parts as those in FIGS. 1 to 4 are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 5, the field member 20 </ b> A includes an upper plate 22 and a lower plate 21, and a moisture-permeable roofing 30 is sandwiched between the upper plate 22 and the lower plate 21. For this reason, the pier 40 is directly installed on the upper plate 22. Therefore, the ventilation plate 42 becomes unnecessary. Similarly, the nose bridge 41 is also installed directly on the upper surface of the upper plate 22 without using the hollow body 43. However, the crosspiece 40 and the nose crosspiece 41 may have the ventilation plate 42 and the hollow body 43, respectively, and may be installed on the field member 20A.

  When combining the field members 20A with each other, as shown in FIGS. 3 and 4, the sleeve portion 23 is brought into contact, and the joining member 24 is placed on the upper portion or the lower portion of the sleeve portion 23 contact portion. The moisture permeable roofing 30 may be overlapped with the plate 21 and fixed by, for example, nailing.

  In the roof structure 1 </ b> A using the field member 20 </ b> A configured as described above, the space between the moisture-permeable roofing 30 and the roof tile 50 has a constant interval in the same direction as the rafter 10. 1 can be ventilated in the same manner as arrows F and G in FIG. Further, even when rainwater or the like enters from the roof tile 50, the rainwater or the like can be discharged to the outside by the upper plate 22 and the moisture-permeable roofing 30.

  Moisture over the space formed by the lower plate 21 of the field member 20A and the moisture-permeable roofing 30 is transmitted to the space of the upper plate 22 of the field member 20A by the moisture-permeable roofing 30, and the ventilation of the upper plate 22 is performed. As a result, moisture is discharged to the outside. For this reason, since moisture does not spread around the field member 20A, wood and the like are hardly perished and durability can be obtained.

  Further, the assembly of the field member 20A and the moisture-permeable roofing 30 is manufactured at a factory, for example, and the field member 20A only needs to be joined (constructed) in accordance with the size of the roof on the site. And since the hollow body 43 is not required, it becomes possible to reduce construction time and construction cost, and also material cost. In addition, when joining the field member 20A, the moisture-permeable roofing 30 is overlapped so that rainwater or the like does not leak.

  As described above, according to the roof structure 1A according to the first modification, moisture in the space around the lower plate 21 is transmitted through the moisture-permeable roofing 30, and ventilation is performed in the space between the upper plate 22 and the roof tile 50. Therefore, it is possible to form the roof structure 1A with a simple structure and sufficient ventilation of the house.

FIG. 6 is a side view showing the field member 20B of the roof structure 1B according to the second modification of the above-described technical reference example . In FIG. 6, the same functional parts as those in FIGS. 1 to 5 are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 6, the field member 20 </ b> B includes an upper plate 22 and a lower plate 21, a moisture-permeable roofing 30 on the upper surface of the upper plate 22, and moisture permeability between the upper plate 22 and the lower plate 21. It has the aluminum sheet 31 which has heat insulation.

  In the roof structure 1 </ b> B configured as described above, on the upper surface of the moisture permeable roofing 30, the space between the moisture permeable roofing 30 and the roof tile 50 is ventilated by the ventilation plate 42 and the hollow body 43 in the same manner as the arrow F in FIG. 1. Is possible. Further, even when rainwater or the like enters from the roof tile 50, rainwater or the like can be discharged to the outside by the ventilation plate 42, the hollow body 43, and the moisture-permeable roofing 30.

  Further, moisture over the space formed by the lower plate 21 of the field member 20B and the aluminum sheet 31 is transmitted to the space of the upper plate 22 of the field member 20B by the aluminum sheet 31, and the ventilation (see FIG. 1 is the same as arrow G in FIG. For this reason, since moisture does not spread around the field member 20B, the wood is less likely to rot and durability can be obtained. In addition, since the aluminum sheet 31 has a heat shielding effect and the space of the field member 20B is divided into two by the aluminum sheet 31, a temperature difference is generated between the space of the lower plate 21 and the space of the upper plate 22, and the heat insulating effect. Have By these heat shielding effect and heat insulating effect, it becomes possible to reduce the influence of the change in the room temperature due to the outside air temperature.

  Furthermore, the moisture permeable roofing 30 on the upper surface of the field member 20B does not allow rainwater or the like to permeate the field member 20B, and moisture or the like in the space of the field member 20B is discharged to the outside by ventilation or moisture permeable roofing 30. As a result, the light passes through the space between the roof tile 50 and the moisture-permeable roofing 30. For this reason, ventilation can be taken around the field member 20B, and since moisture does not flow, the wood is less likely to rot and durability can be obtained.

  Here, the aluminum sheet 31 provided between the lower plate 21 and the upper plate 22 may be used as the moisture-permeable roofing 30. By using the moisture permeable roofing 30, the heat shielding performance is slightly lowered, but it is possible to generate a heat insulating effect at a low cost.

  As described above, according to the roof structure 1B according to the second modification, ventilation is possible by providing the aluminum sheet 31 between the lower plate 21 and the upper plate 22 of the field member 20B, and The roof structure 1B that can have high heat shielding properties and heat insulation properties can be formed.

FIG. 7 is a side view showing a field member 20C of the roof structure 1C according to the third modification of the above-described technical reference example , and FIG. 8 is a side view showing a combination of the field members 20C. 7 and 8, the same functional parts as those in FIGS. 1 to 6 are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 7, the field member 20 </ b> C includes an upper plate 22 and a lower plate 21, and an aluminum sheet 31 having moisture permeability and heat shielding properties on the lower surface of the lower plate 21. For this reason, the pier 40 is directly installed on the upper plate 22. Therefore, the ventilation plate 42 becomes unnecessary. Similarly, the nose bridge 41 is also installed directly on the upper surface of the upper plate 22 without using the hollow body 43. However, the crosspiece 40 and the nose crosspiece 41 may have the ventilation plate 42 and the hollow body 43, respectively, and may be installed on the field member 20C.

  In addition, when combining the field members 20C, as shown in FIG. 8, the sleeves 23 are adjacent to each other, and an aluminum sheet 31 is sandwiched between them, and is overlapped on the upper surface of the lower plate 21 of either one of the field members 20C. In addition, the joining member 24 may be fixed thereon by, for example, nailing.

  In the roof structure 1 </ b> C configured as described above, on the upper surface of the aluminum sheet 31, the space between the aluminum sheet 31 and the roof tile 50 is ventilated by the lower plate 21 and the upper plate 22 in the same manner as the arrows F and G in FIG. 1. Is possible. Further, even when rainwater or the like enters from the roof tile 50, rainwater or the like moves to the aluminum sheet 31, and there is a gap generated during construction between the lower plate 21 and the aluminum sheet 31, and therefore rainwater or the like is generated from this gap. Can be discharged. In addition, in order to improve drainage efficiency of rainwater or the like, a groove may be cut in the lower plate 21 or a plate material for providing a gap between the lower plate 21 and the aluminum sheet 31 may be disposed.

  Further, the moisture in the space formed by the rafter 10 and the aluminum sheet 31 is transmitted to the space of the field member 20C by the aluminum sheet 31, and the ventilation of the lower plate 21 and the upper plate 22 (arrows F and G in FIG. 1). The moisture is discharged to the outside. For this reason, since moisture does not go around the rafters, the wood is less likely to rot and durability can be obtained. Further, the aluminum sheet 31 has a heat shielding effect. This heat shielding effect makes it possible to reduce the influence of changes in room temperature due to the outside air temperature.

  Furthermore, when the roof tiles 50 are fastened together by nail driving, the aluminum sheet 31 is provided on the lower surface of the lower plate 21 as in the present modified example, so that the joining member 24 and the lower plate 21 can be formed even when nailing or the like is performed. The nail or the like does not reach the aluminum sheet 31. Due to the nature of the aluminum sheet 31, when nails are struck, rainwater or the like may leak from the nailed location. For this reason, some measures must be taken when the nail penetrates to the aluminum sheet 31. However, since this measure does not require a measure, the construction cost is reduced.

  Further, when installing the roof tile after laying the aluminum sheet 31 during construction, sunlight or the like reflects the aluminum sheet 31 and the reflected light significantly reduces workability. By installing the grid-like field member 20C on the aluminum sheet 31, reflected light is reduced, and workability can be improved.

  As described above, according to the roof structure 1 </ b> C according to the third modified example, by providing the aluminum sheet 31 on the lower surface of the lower plate 21 of the field member 20 </ b> C, ventilation is possible and high heat shielding properties are provided. It is possible to form a roof structure 1C that can be used.

Further, when the aluminum sheet 31 is provided between the lower plate 21 and the upper plate 22, when laying the roof after laying the aluminum sheet 31 during construction, sunlight or the like reflects the aluminum sheet 31, Although the workability is remarkably deteriorated by the reflected light, the reflected light is reduced and the workability can be improved by installing the grid-like field member 20C on the aluminum sheet 31 as in this modification. It becomes. However, as described above, aluminum sheet does not maintain waterproofness because rainwater etc. leaks by nails etc. during construction, so rainwater etc. by laying rubber sheet or resin sheet etc. Construction for preventing leakage of water (that is, having waterproof properties) may be performed.

  Moreover, although it demonstrated that a joining member was used for the coupling | bonding of a field member, even if it provides a joining member in a field member, it is applicable, or even if a field member is adjacent, a field member is fixed and waterproofness is neat It can be applied by having it. In addition to these, even if the angle of intersection of the lower plate and the upper plate used for the base member (field member) is not orthogonal (90 degrees), the present invention can be applied. Of course, various modifications can be made without departing from the scope of the present invention.
