  Hereinafter, the roof structure of the first embodiment will be described in more detail.

  The roof base material 2 is a plate-like member provided on the roof structure material. The dimension shape of the roof base material 2 is formed according to the shape of the roof. The roof base material 2 is, for example, wooden. The roof base material 2 is, for example, a field plate. The roof structure material of this embodiment is a rafter 1. For this reason, the roof base material 2 is fixed on the rafter 1. The roof base material 2 is fixed on the rafter 1 by nailing, screwing or the like. In addition, although this embodiment is a roof structure in a wooden building, this roof structure may be applied to a steel structure building or a reinforced concrete structure.

  The heat insulating material 3 is a member having heat insulating properties. It is preferable that the heat insulating material 3 of this embodiment has rigidity further. The heat insulating material 3 is, for example, a foamed plastic heat insulating material or an inorganic foam heat insulating material. The foamed plastic heat insulating material is, for example, an extruded polystyrene foam, a beaded polystyrene foam, or a phenol foam. The inorganic foam-based heat insulating material is, for example, a pearlite plate or a calcium carbonate-based foam heat insulating material.

  The heat insulating material 3 of this embodiment is arrange | positioned on the roof base material 2 (refer FIG. 1). The heat insulating material 3 may be bonded to the roof base material 2 with an adhesive or the like. The heat insulating material 3 may be disposed directly on the roof base material 2, and another member such as a moistureproof sheet, a waterproof sheet, a soundproof sheet, or the like may be interposed between the heat insulating material 3 and the roof base material 2. These separate members may be provided on the upper surface of the heat insulating material 3, or may be provided on either the upper or lower side or the upper and lower sides by selecting another member having a necessary function according to the purpose. Moreover, these separate members may be provided in the heat insulating material 3 in advance by an adhesive, fusion, or the like, and further separate members may be protruded outward from the heat insulating material 3.

  In the heat insulating material 3 of this embodiment, a long lateral groove 31 is formed in a direction intersecting with the eaves-ridge direction (see FIG. 2). The lateral groove 31 is formed over the entire length in the direction intersecting the eaves-ridge direction of the heat insulating material 3. There are a plurality of lateral grooves 31. The plurality of lateral grooves 31 are arranged at substantially equal intervals along the slope of the roof.

  In the heat insulating material 3 of the present embodiment, a long vertical groove 32 is formed in the roof eaves direction (see FIG. 3). The longitudinal groove 32 is formed over the entire length in the eaves-ridge direction of the heat insulating material 3. There are a plurality of longitudinal grooves 32. The plurality of longitudinal grooves 32 are arranged in a direction perpendicular to the eaves-ridge direction of the roof.

  In this embodiment, the crosspiece 4 is arrange | positioned in the horizontal groove 31 (refer FIG. 1). The crosspiece 4 is a long member having substantially the same dimensions as the lateral groove 31. In this case, the vertical groove 32 has a bottom surface below the horizontal groove 31 and the crosspiece 4, and crosses the crosspiece 4. Although the crosspiece 4 is not restrictive, it is formed from one or more materials selected from, for example, wood, metal, and resin. When the crosspiece 4 is made of metal, the crosspiece 4 may have, for example, a hollow shape with a rectangular cross section or a U-shaped cross section.

  In the present embodiment, the upper surface of the crosspiece 4 and the upper surface of the heat insulating material 3 are flush with each other. Here, the term “equal” means that there is no step between the upper surface of the heat insulating material 3 and the upper surface of the crosspiece 4, or that the step is slight and can be regarded as having substantially no step.

  In the state in which the crosspiece 4 is disposed in the lateral groove 31, the crosspiece fixture 7 is driven. In this embodiment, the crosspiece fixture 7 is driven from the crosspiece 4 through the heat insulating material 3 and the roof base material 2 to the rafter 1. For this reason, the heat insulating material 3 is fixed on the roof base material 2 by the crosspiece 4. Further, when the position of the rafter 1 is difficult to understand, it is not particularly necessary to drive the rafter 1. The crosspiece fixture 7 may be driven from the crosspiece 4 through the heat insulating material 3 to the roof base material 2 without being driven into the rafter 1, for example. In this case, it is preferable to increase the number of crosspiece fixing tools 7 to be driven into the roof base material 2 rather than driving the crosspiece fixing tools 7 into the rafters 1. The crosspiece fixture 7 is, for example, a nail or a screw.

  The roof material 5 may be installed directly on the heat insulating material 3 or may be installed on the heat insulating material 3 via another member.

  In this embodiment, the lower brazing material 8 is arrange | positioned on the heat insulating material 3 (refer FIG. 1). The roof material 5 is installed on the heat insulating material 3 via the lower roof material 8. The lower eaves material 8 is, for example, a waterproof sheet, and more specifically, asphalt roofing. The lower brace material 8 is a transparent member having, for example, a polyethylene resin as a main component. In this case, even after the lower roofing material 8 is installed, the crosspiece 4 can be seen through the lower roofing material 8, and the construction of the roofing material 5 becomes easy.

  In this embodiment, the roofing material 5 is installed on the heat insulating material 3 provided with the lower roofing material 8. The roofing material 5 of the present embodiment is a slate tile having a substantially rectangular shape in plan view. All the roofing materials 5 are formed in the same shape. A plurality of roofing materials 5 are provided in the direction of the eaves of the roof. Further, a plurality of roofing materials 5 are provided in a direction orthogonal to the eaves-ridge direction of the roof.

  The roof material 5 of the present embodiment includes a first roof material 51, a second roof material 52, and a third roof material 53. The eaves side end of the second roof material 52 overlaps the ridge side end of the first roof material 51. The eaves side end of the third roof material 53 overlaps the ridge side end of the second roof material 52.

  In the present embodiment, the fixture 6 is driven into the crosspiece 4 from the ridge side portion of the second roof material 52 rather than the portion where the first roof material 51 and the second roof material 52 overlap. The fixture 6 is, for example, a nail or a screw. Here, the ridge-side edge of the first roof material 51 is preferably located on the crosspiece 4. In this case, when the fixture 6 is driven into the second roof material 52, the ridge-side edge of the first roof material 51 is supported by the crosspiece 4.

  Moreover, although the fixture 6 is driven into the crosspiece 4 at a position on the ridge side with respect to the crosspiece fixture 7, the present invention is not limited to this. For example, as shown in FIG. 4, the fixture 6 may be driven into the crosspiece 4 at a position closer to the eaves than the crosspiece fixture 7. Since the fixture 6 in this case is located immediately on the ridge side edge of the first roof material 51, the gap between the fixture 6 and the ridge side edge of the first roof material 51 is small. For this reason, when driving the fixture 6 into the second roof material 52, the load applied to the second roof material 52 can be received by the first roof material 51. Also, the crack of the second roof material 52 can be suppressed. The driving position of the fixture 6 can be applied not only in this embodiment but also in the roof structures according to the second to fourth embodiments described below.

  A third roof material 53 is disposed on the portion of the second roof material 52 where the fixture 6 is driven. For this reason, the fixture 6 is not seen from the top of the roof, and the appearance of the roof is excellent. In addition, the eaves side edge of the third roof material 53 is located on the eaves side with respect to the ridge side edge of the first roof material 51. For this reason, rainwater etc. are hard to penetrate | invade on the 1st roof material 51, and the waterproofness of a roof improves. That is, on the crosspiece 4, the three roof materials of the first roof material 51, the second roof material 52, and the third roof material 53 overlap each other.

  In this embodiment, after the heat insulating material 3 in which the horizontal groove 31 is formed is installed on the roof base material 2, the crosspiece 4 may be arranged in the horizontal groove 31, or the heat insulation in which the crosspiece 4 is arranged in the horizontal groove 31 in advance. The material 3 may be installed on the roof base material 2. In the case where the crosspieces 4 are arranged in advance in the lateral grooves 31, it is not necessary to install the crosspieces 4 on the roof, so that it is possible to reduce the labor of construction on the roof.

  In the roof structure of the present embodiment, the crosspiece 4 is fixed to the rafter 1 by the crosspiece fixture 7 via the heat insulating material 3 and the roof base material 2, so that the heat insulating material 3 is placed on the roof base material 2. It can be firmly fixed.

  Further, since the roof material 5 is fixed to the crosspiece 4 embedded in the heat insulating material 3, the roof material 5 can be installed on the heat insulating material 3 without providing a reinforcing plate covering the heat insulating material 3.

  Furthermore, in the roof structure of this embodiment, the heat insulating material 3 has rigidity, and the roof material 5 is fixed to the crosspiece 4 embedded in the heat insulating material 3. In this case, the load applied when the roofing material 5 is fixed by the fixing tool 6 is once applied to the crosspiece 4 and then distributed to the rigid heat insulating material 3 through the crosspiece 4. That is, no direct load is applied from the fixture 6 to the heat insulating material 3. For this reason, compared with the case where a roofing material is directly fixed to the heat insulating material 3, or the case where the crosspiece 4 is not embedded in the heat insulating material 3 and installed on the heat insulating material 3, the heat insulating material 3 is less likely to be damaged.

  In the roof structure of the present embodiment, since the longitudinal grooves 32 provided in the heat insulating material 3 are formed, the air permeability of the entire roof can be ensured, and rainwater or the like that has entered from the roof ridge is brought to the eaves side. Can be discharged.

  In the roof structure of this embodiment, since the lower armor 8 is installed on the heat insulating material 3, the waterproofness of the roof can be ensured. Therefore, when the heat insulating material 3 is comprised from a some heat insulating material, the waterproofness in the abutting part and heat coupling | bonding part of heat insulating materials is securable. Moreover, even if the heat insulating material 3 is a heat insulating material weak to water, it becomes possible to use it.

  Moreover, in the roof structure which concerns on 2nd embodiment, as shown in FIG. 5, the roof base material 2 is formed from the cementitious material. The roof base material 2 in this case is a roof structure material in a steel structure building or a reinforced concrete structure, for example.

  In this embodiment, the heat insulating material 3 is installed on the concrete roof base material 2. The heat insulating material 3 of this embodiment has rigidity. In the roof structure of the present embodiment, a moisture-proof sheet 21 is interposed between the roof base material 2 and the heat insulating material 3. The heat insulating material 3 may be installed directly on the roof base material 2.

  In this embodiment, the crosspiece 4 is driven by the crosspiece fixture 7 through the heat insulating material 3 to the roof base material 2. Thereby, the heat insulating material 3 is being fixed on the roof base material 2. FIG. The crosspiece fixture 7 in the present embodiment is, for example, a concrete screw.

  In the present embodiment, in particular, when the heat insulating material 3 having rigidity is produced and then installed on the roof base material 2 made of concrete, the roof base material made of concrete is made of a cement-based material. There is no need to wait until it hardens as in the case of installing a nail or screw retaining layer such as pearlite mortar, and the roof material 5 can be installed on the heat insulating material 3 immediately after the heat insulating material 3 is installed. This can shorten the time required for construction.

  It is also possible to provide the heat insulating material 3 on the existing roof. For example, after removing the existing roof material of the existing roof provided with pearlite mortar, the heat insulating material 3 may be installed on the pearlite mortar.

  In the roof structure according to the third embodiment, as shown in FIG. 6, a plurality of existing roof materials 9 are provided between the roof base material 2 and the heat insulating material 3. That is, the existing roof material 9 of the existing roof may be left as it is.

  The existing roofing material 9 is a roofing material that is originally installed in an existing building. The existing roofing material 9 is, for example, a slate tile having a rectangular shape in plan view. All the existing roofing materials 9 have the same shape. A plurality of existing roofing materials 9 are installed on the roof base material 2 in the direction of the roof eaves and in the direction orthogonal to the direction of the eaves of the roof. The existing roofing material 9 may be installed directly on the roof base material 2 or may be installed on the roof base material 2 after a waterproof sheet or the like is disposed.

  In the present embodiment, the heat insulating material 3 is disposed on the existing roof material 9. In other words, the heat insulating material 3 of this embodiment is arrange | positioned on the roof of the existing building. The heat insulating material 3 may be disposed directly on the existing roof material 9, and another member such as a moisture-proof sheet, a waterproof sheet, or a soundproof sheet may be interposed between the heat insulating material 3 and the existing roof material 9.

  In the present embodiment, the crosspiece 4 is driven by the crosspiece fixture 7 through the heat insulating material 3, the existing roofing material 9, and the roof base material 2 to the rafter 1. Thereby, the heat insulating material 3 is being fixed on the existing roofing material 9. FIG.

  In the roof structure of this embodiment, since the heat insulating material 3 is arrange | positioned on the existing roof material 9, the heat insulation of the building in which the existing roof material 9 is installed previously can be improved. That is, the roof can be reformed by constructing the roof structure of the present embodiment.

  Moreover, in the roof structure which concerns on 4th embodiment, as shown in FIG. 7, the shape of the back surface of the heat insulating material 3 corresponds with the shape of the some existing roof material 9. As shown in FIG. Since the existing roofing material 9 is a roofing material that is originally installed on the roof of the building, the shape of the back surface of the heat insulating material 3 of this embodiment matches the shape of the roof of the existing building. .

  Matching in the present embodiment has a shape in which the back surface of the heat insulating material 3 includes a plurality of planes and a plurality of steps corresponding to a plurality of planes and a plurality of steps formed from a plurality of existing roofing materials 9, respectively. That means. The plurality of planes and the plurality of steps on the back surface of the heat insulating material 3 and the plurality of planes and the plurality of steps composed of the plurality of existing roofing materials 9 are preferably in contact with each other without any gap, There may be some gaps.

  In the roof structure of this embodiment, since the back surface of the heat insulating material 3 matches the shape of the plurality of existing roof materials 9, the heat insulating material 3 can be stably installed on the plurality of existing roof materials 9. .
