  In buildings such as houses, eaves ceilings may be provided for the eaves of the roof. In the eaves ceiling, the eaves top plate is provided in a state of being spanned between the outer wall and the eaves of the roof, and the eave top plate forms the ceiling surface of the eaves top part. The eaves side end of the eaves top plate is fixed to, for example, a nose cover part of the eaves, and the outer wall side end is fixed to the outer wall, for example, via a bracket. As a configuration in which the outer wall side end portion of the eaves top plate is supported by the bracket, there is a configuration in which the bracket is attached to the outer wall with a screw or the like at a position spaced downward from the upper end portion of the outer wall (for example, Patent Document 1). .

JP 2009-191493 A

  Here, in the configuration in which the outer wall has a plurality of outer wall surfaces arranged side by side, the steps extending along the height direction of the outer wall due to different thickness dimensions of adjacent outer wall surfaces. May be formed. For example, in the configuration in which the outdoor side surface of the wall material having the larger thickness dimension among the adjacent outer wall surface materials is arranged at a position where the outdoor side surface of the wall material having the smaller thickness dimension projects to the outdoor side, these wall surfaces When the eaves top plate is installed in a state of being spanned in the wall width direction with respect to the material, the gap between the thinner wall surface material and the eaves top plate is Larger than the gap between. That is, the separation distance between the eaves top plate and the thin wall material is different between the thin wall material and the thick wall material.

  Therefore, for example, select a larger support bracket to be attached to the thinner wall material than the support bracket to be attached to the thicker wall material, so that it matches the separation distance between the eaves top plate and the wall material. It is conceivable to use different types of support brackets.

  However, when multiple types of support brackets are used properly, the work load on fixing the eaves top plate to the outer wall increases by preparing multiple types of support brackets and by carrying multiple types of support brackets at the construction site. There is a concern to do. In addition, there is a concern about an increase in cost burden by manufacturing a plurality of support brackets as dedicated products.

  The present invention has been made in view of the circumstances exemplified above, and in a configuration in which the eaves top plate is provided in a state of straddling the steps of the outer wall surface, the eaves top plate is suitably attached to the outer wall. The main purpose is to provide an eave-top support structure that can be used.

  Hereinafter, means and the like effective for solving the above-described problems will be described while showing functions and effects as necessary. In the following, for easy understanding, the corresponding configuration in the embodiment of the invention is appropriately shown in parentheses, but is not limited to the specific configuration shown in parentheses.

  The eaves top plate support structure for a building of the first invention is provided with an eaves top plate (eave top plate 46) at the eaves top part of the building (building 10), and a support bracket (support bracket) for supporting the eave top plate 51) is attached to the outer wall (outer wall 11), and the support bracket includes a wall fixing portion (wall fixing portion 53) fixed to the outer wall, and an eave ceiling support portion (eave ceiling support) that supports the eaves top plate. Part 54), and the outer wall includes a first wall surface (the wall surface of the unwalled wall surface material 21A, the wall surface of the first wall surface material 81A) and the first wall surface. And the second wall surface (the wall surface of the wall surface material 21B with the handle and the wall surface of the second wall surface material 81B) disposed side by side and disposed at a position protruding outward from the first wall surface. The eaves top plate has a step between the first wall surface and the second wall surface in the wall width direction of the outer wall. The wall fixing portion of the support bracket attached to the first wall surface and the first wall bracket are supported by the support brackets attached to the first wall surface and the second wall surface. A spacer member (spacer member 71) for adjusting the position of the support bracket with respect to the first wall surface material is provided between the first wall surface material and the first wall surface material.

  According to the first invention, in the outer wall disposed at the position where the second wall surface protrudes to the outdoor side from the first wall surface, the separation distance between the spacer member and the eaves top plate is such that the first wall surface and the eaves top plate are Therefore, it is not necessary to make the support bracket attached to the second wall surface larger than the support bracket attached to the first wall surface. In this case, there is no need to prepare multiple types of support brackets as dedicated items or use them separately even if the eaves top plate is provided across the steps of the outer wall surface. It is possible to suppress an increase in work burden and cost burden related to fixing. That is, the eaves top plate can be suitably attached to the outer wall.

  In a second aspect based on the first aspect, the upper end of the spacer member is arranged at the same height as the upper end of the wall fixing portion.

  When attaching the support bracket to the wall surface of the outer wall, it is considered that the operator attaches a mark indicating the attachment position of the support bracket to the wall surface and aligns the support bracket with reference to the mark. Here, when the spacer member is sandwiched between the wall surface and the support bracket, there is a concern that the mark indicating the mounting position of the support bracket is covered with the spacer member.

  On the other hand, according to the second invention, since the spacer member and the wall fixing portion are aligned at the upper ends, a mark indicating the height position of the upper end of the wall fixing portion is attached to the first wall surface. In this case, the upper end of the spacer member can be aligned based on the mark, and the upper end of the wall fixing portion can be aligned based on the upper end of the spacer member. Thereby, even if it is the structure where a support bracket is attached to a 1st wall surface on both sides of a spacer member, both a spacer member and a support bracket can be arrange | positioned in an appropriate position.

  According to a third invention, in the first or second invention, the spacer member has a plurality of plate members (plate members 72 and 73) stacked on each other, and these plate members have a wall thickness of the outer wall. It arrange | positions between the said wall fixing | fixed part and the said 1st wall surface in the direction aligned in a direction.

  According to the third invention, the thickness dimension of the spacer member can be adjusted so that the outdoor side surface of the spacer member is flush with the second wall surface by performing an easy operation of changing the number of plate members. it can. In this case, it is not necessary to produce a spacer member as a dedicated product that matches the separation distance between the first wall surface and the eaves top plate, and the spacer member can be formed by using a plurality of general-purpose plate materials. Reduction of cost burden can be realized.

  In a fourth aspect based on the third aspect, the plurality of plate members of the spacer member include a first plate member (first plate member 72) and a second plate member (second plate) having a thickness dimension smaller than that of the first plate member. Plate material 73).

  In the configuration in which at least one of the first wall surface and the second wall surface is arranged in the wall width direction, a step between the first wall surface and the second wall surface is formed in the wall thickness direction. The case where the height dimension of the level | step difference in a direction differs for every level | step difference resulting from the manufacturing error of the wall material which forms a 1st wall surface or a 2nd wall surface, the installation error of a wall surface material, etc. is assumed. In this case, if the spacer member having the same thickness dimension is installed for all the steps, the outdoor side surface of the spacer member is not flush with the second wall surface depending on the step, and the position of the support bracket with respect to the eaves top plate is shifted. There is a concern that the eaves top support part of the support bracket cannot support the eaves top plate in an appropriate state.

  On the other hand, according to the fourth invention, when the thickness dimension of the spacer member is adjusted by changing the number of plate members, the number of the first plate member or the second plate member is selected. Thereby, the adjustment width | variety of the thickness dimension of a spacer member can be increased / decreased. For example, when there is a slight step between the second wall surface and the outdoor side surface of the spacer member, the height of the step is smaller than the thickness of the first plate, but the same as the thickness of the second plate. In this case, the outdoor side surface of the spacer member can be arranged flush with the second wall surface by increasing or decreasing the number of second plate members. Thereby, the eaves top plate can be supported in an appropriate state on the eaves top support part of the support bracket.

  According to a fifth invention, in any one of the first to fourth inventions, the outer wall is a first wall surface that forms the first wall surface as an outer wall material (outer wall material 21) that forms the wall surface of the outer wall. And a first wall surface material 21A, a first wall surface material 81A, and a second wall surface material (patterned wall surface material 21B, second wall surface material 81B) forming the second wall surface. The wall surface material and the second wall surface material are arranged side by side in the wall width direction of the outer wall.

  According to the fifth invention, the spacer member is used for the outer wall in which the first wall surface material and the second wall surface material have different thicknesses so that a step is generated between the first wall surface and the second wall surface. By doing so, an eaves top board can be suitably attached via a support bracket.

  In a sixth aspect based on the fifth aspect, the outer wall is provided on the indoor side of the outer wall surface material, and has an outer wall base (base member 23) that supports the outer wall surface material. The material has a face material main body (face material main body 24) fixed to the outer wall base, and the second wall surface material is provided on the outdoor side of the face material main body and is a pattern on the second wall surface. The thickness dimension of the spacer member is larger than that of the first wall material, and the spacer member has a thickness dimension of the pattern forming layer. It is the same as the thickness dimension.

  According to the sixth invention, since the thickness dimension of the spacer member may be the same as the thickness dimension of the pattern forming layer of the second wall surface material, the selection work of the plate material used as the spacer member and the production work of the spacer member Can be facilitated.

  Moreover, in the wall surface material, it is considered that the outdoor side surface of the face material main body is flat (unevenness is small) compared to the outdoor side surface of the pattern forming layer because the pattern is not formed. That is, when the first wall surface is formed by the face material body of the first wall surface material, the first wall surface is flat compared to the second wall surface formed by the pattern forming layer of the second wall surface material. It is thought that there is. For this reason, in the configuration in which the spacer member is stacked on the first wall surface, it is possible to suppress the spacer member from being inclined in the wall thickness direction due to the unevenness of the wall surface, compared to the configuration in which the spacer member is stacked on the second wall surface. Therefore, in the configuration in which the spacer member is sandwiched between the outer wall and the support bracket, the support bracket can be installed in an appropriate state rather than being inclined with respect to the outer wall in the wall thickness direction.

  In a seventh aspect based on any one of the first to sixth aspects, the boundary between the outer wall and the eaves top plate straddles a step between the first wall surface and the second wall surface. A parting member (parting member 65) extending along the wall width direction is provided, and the parting member is hung on each support bracket attached to the first wall surface and the second wall surface. In the state, it is supported by these support brackets.

  According to the seventh invention, in the configuration in which the parting member of the eaves top plate is supported by the support bracket, the spacer member is provided between the first wall surface and the support bracket. The relative positional relationship with respect to the parting member is made uniform by the attached support bracket and the support bracket attached to the second wall surface. Therefore, it is possible to realize a configuration in which the support bracket supports both the eaves top plate and the parting member in an appropriate state.

  In an eighth aspect based on the seventh aspect, the eaves top plate is supported by the support bracket in a state of being placed on the eaves top support part, and the parting member is the eave ceiling support part. Is provided in a state of covering from below.

  Regarding the boundary between the eaves top plate and the outer wall, the gap between the first wall surface and the eaves top plate is lower than the gap between the second wall surface and the eaves top plate. When looking up from above, there is a concern that the support bracket attached to the first wall surface is more conspicuous than the support bracket attached to the second wall surface.

  On the other hand, according to the eighth invention, since the eaves top support part of the support bracket is covered with the parting member, the support bracket attached to the first wall surface is not conspicuous. A configuration in which the support bracket attached to the second wall surface is not conspicuous can be realized.

  According to a ninth invention, in any one of the first to eighth inventions, the support bracket is fixed to the outer wall by being driven into the outer wall through the wall fixing portion and the spacer member. The fixing tool (fixing tool 57) is provided.

  According to the ninth aspect of the invention, even if the spacer member is provided between the wall fixing portion of the support bracket and the first wall surface, the wall fixing portion and the spacer member together with the first wall surface (outer wall). Can be suitably fixed.

The length dimension of the fixing tool 57 is larger than the thickness dimension D2 of the spacer member 71 (thickness dimension D1 of the pattern forming layer 25), and the length of the fixing tool 57 does not reach the hollow portion 22 of the face material body 24. Has been. For example, in the face material main body 24, when the thickness dimension of the outdoor side portion of the hollow portion 22 is D3, the length dimension of the fixture 57 is larger than D2 but smaller than D2 + D3. For this reason, even if the fixing tool 57 is driven into either the handle-less wall material 21A or the handle-made wall material 21B, the tip thereof reaches the face material body 24, and the support bracket 51 is attached to the face materials 21A and 21B. It is fixed in an appropriate state.

  The width dimension of the spacer member 71 is larger than the width dimension of the wall fixing portion 53 of the support bracket 51. In this case, the entire wall fixing portion 53 is overlaid on the spacer member 71 in the wall width direction. In addition, the height dimension of the spacer member 71 is smaller than the height dimension of the wall fixing portion 53 of the support bracket 51. In this case, the upper end of the wall fixing portion 53 is disposed at the same height as the upper end of the support bracket 51, and the wall fixing portion 53 protrudes downward from the spacer member 71.

  In the support bracket 51, the lower part of the wall fixing part 53 and the connecting part 55 are elastically deformed, so that the eaves ceiling support part 54 can be displaced in the wall thickness direction. In the support bracket 51 attached to either the unpatterned wall material 21A or the patterned wall material 21B, the eave ceiling support portion 54 is separated from the wall surface to the outdoor side, and the eave ceiling support portion 54 is on the side away from the wall surface. Of course, it is possible to move to the side closer to the wall surface. The separation distance between the eaves-top support portion 54 and the wall surface is smaller in the configuration related to the patterned wall material 21B than in the configuration related to the non-patterned wall material 21A.

  A net member 74 is provided at a boundary portion between the eaves top plate 46 and the outer wall 11 so as to close a gap between the eaves top support portion 54 and the outer wall 11. The net member 74 is formed in a long plate shape and extends along a gap between the wall fixing portion 53 and the outer wall 11. The net member 74 is placed on the eave ceiling support portion 54 on the upper side of the eave ceiling plate 46, and is stretched over the eave ceiling support portion 54 and the outer wall 11 in the wall thickness direction. It has become. While the width dimension of the net member 74 in the wall thickness direction is larger than the separation distance between the wall fixing portion 53 and the unpatterned wall surface material 21A, the distance between the downwardly extending portion 55b of the connecting portion 55 and the wall surface material 21B with the handle. It is smaller than the distance. In other words, the support bracket 51 extends downward on the upper side of the eaves top plate 46 regardless of whether the support bracket 51 is attached to the handle-less wall material 21A or the support bracket 51 is attached to the handle-attached wall material 21B. A net member 74 can be installed between the portion 55 b and the outer wall 11.

  As shown in FIGS. 3A and 3B, the spacer member 71 is formed in a substantially rectangular shape as a whole. The spacer member 71 is installed in a direction in which the longitudinal direction is the wall width direction. The spacer member 71 has a plurality of (for example, two) plate members 72 and 73 that are overlapped with each other on the plate surfaces. The plate materials 72 and 73 are formed in a substantially rectangular shape by, for example, a synthetic resin material, and have the same width dimension and height dimension. On the other hand, the thickness dimension D2a (for example, 5 mm) of the first plate material 72 among the sheet materials 72 and 73 is larger than the thickness dimension D3 (for example, 3 mm) of the second plate material 73. In the spacer member 71, the 1st board | plate material 72 is arrange | positioned at the outdoor side, and the 2nd board | plate material 73 is arrange | positioned at the outer wall 11 side. In this case, the wall fixing portion 53 of the support bracket 51 is overlapped with the first plate member 72, and the second plate member 73 is overlapped with the patternless wall surface member 21A.

  The plate materials 72 and 73 each have a large number of recesses 75 on both plate surfaces. For example, the recesses 75 are hexagonal and are regularly arranged at predetermined intervals along the plate surface. In this case, a large number of recesses 75 are also disposed on both plate surfaces of the spacer member 71. For this reason, even if a minute convex portion such as a lump of paint exists on the wall surface of the handle-less wall surface material 21A, the spacer member 71 is installed in a state where the convex portion enters the concave portion 75 of the spacer member 71. By doing so, the spacer member 71 can be arranged in parallel to the wall surface of the handleless wall surface material 21A. Further, even if a minute convex portion exists in the wall fixing portion 53 of the support bracket 51, the wall fixing portion 53 is in the state in which the convex portion enters the concave portion 75 of the spacer member 71. The wall fixing portion 53 can be arranged in parallel to the plate surface of the spacer member 71.

  As shown in FIG. 4, a mark A such as a straight line is given to the wall surface of the pattern-less wall surface material 21 </ b> A by a marking operation, and the support bracket 51 is aligned with the mark A as a reference. The mark A is a mark indicating the upper end position of the wall fixing portion 53 of the support bracket 51. Here, as described above, since the upper end of the wall fixing portion 53 of the support bracket 51 and the upper end of the spacer member 71 are arranged at the same height position, the mark A also indicates the upper end position of the spacer member 71. Will be. The mark A is also given to the wall surface material 21B with the handle, and the height position of the support bracket 51 attached to the wall surface material 21B with the handle is also set based on the mark A.

  A plurality of support brackets 51 are attached to the non-patterned wall member 21A. In this case, a spacer member 71 is sandwiched between the wall fixing portion 53 of each support bracket 51 and the handle-less wall surface material 21A. For this reason, in addition to the support bracket 51, a plurality of spacer members 71 are also arranged at predetermined intervals along the wall width direction.

  In the eaves top portion, in addition to the support bracket 51, a plurality of eaves top plates 46 and parting members 65 are arranged side by side along the wall width direction. In the adjacent eaves top plates 46, convex portions are provided on one of the end surfaces facing each other, and concave portions are provided on the other, and the eaves top plates 46 are fitted together by fitting the convex portions and the concave portions. Are connected. The parting member 65 is a long member extending along the end of the eaves top plate 46, and the adjacent parting members 65 are connected by a connecting member 66. The connecting member 66 is inserted inside the cover portion 65 a of the parting member 65, and is connected to the parting member 65 by being bridged between the adjacent parting members 65.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  Since the thickness dimension D2 of the spacer member 71 is the same as the thickness dimension D1 of the handle forming layer 25 of the patterned wall surface material 21B, the positional relationship with respect to the eaves top plate 46 in the wall thickness direction is attached to the unpatterned wall surface material 21A. It can be made the same with the support bracket 51 made and the support bracket 51 attached to the wall surface material 21B with a handle. For this reason, the end of the eaves top plate 46 enters the support groove 54a of the eaves top support part 54 properly and is supported without making the support bracket 51 attached to the wall surface 21A having no handle large. Can be. For this reason, it is not necessary to prepare or use a plurality of types of support brackets 51 as dedicated products in accordance with each of the pattern-less wall material 21A and the patterned wall material 21B. Thereby, it is possible to suppress an increase in work burden and cost burden regarding the fixing of the eaves top plate 46 to the outer wall 11.

  Since the upper end of the spacer member 71 is disposed at the same height as the upper end of the wall fixing portion 53 of the support bracket 51, the upper end of the spacer member 71 is disposed at a position higher than the upper end of the wall fixing portion 53; In contrast, it can be avoided that the mark A is obscured by the spacer member 71. For this reason, even if the spacer member 71 is sandwiched between the handle-less wall surface material 21 </ b> A and the support bracket 51, the mounting position of the support bracket 51 can be accurately set with reference to the mark A.

  Since the spacer member 71 includes a plurality of plate members 72 and 73, it is not necessary to manufacture the spacer member 71 as a dedicated product in accordance with the thickness dimension D1 of the pattern forming layer 25, and a general-purpose plate member is used as the plate members 72 and 73. As a plurality of spacer members 71, the spacer member 71 can be formed. As a result, a reduction in cost burden regarding the spacer member 71 can be realized. Further, the thickness dimension D2 of the spacer member 71 can be easily changed by changing the number of the plate materials 72 and 73 to be stacked.

  Since the wall surface of the pattern-less wall surface material 21A is formed by the outdoor side surface of the surface material body 24, it is easier to secure a flat portion than the wall surface of the wall surface material 21B with a pattern. For this reason, in the configuration in which the spacer member 71 is stacked on the wall surface of the handle-less wall surface material 21A, it is possible to suppress the spacer member 71 from being inclined in the wall thickness direction due to the unevenness of the wall surface. Therefore, in the configuration in which the spacer member 71 is sandwiched between the handle-less wall surface material 21 </ b> A and the support bracket 51, the support bracket 51 is installed in an appropriate state instead of being inclined with respect to the outer wall 11 in the wall thickness direction. As a result, the eaves top plate 46 can be inserted into the support groove 54a of the eaves top support part 54 of the support bracket 51 in an appropriate state.

  In the configuration in which the parting member 65 is supported by the support bracket 51, the relative position of each support bracket 51 with respect to the eaves top plate 46 is made uniform by the spacer member 71, so that the positional relationship with respect to the eaves top plate 46 is not patterned. Even if the material 21 </ b> A is different from the wall surface material 21 </ b> B with the handle, it is possible to maintain the state in which the parting member 65 extends linearly along the end of the eaves top plate 46. Thereby, unlike the configuration in which the parting member 65 is distorted with respect to the end portion of the eaves top plate 46, for example, it is possible to avoid that the designability of the eaves part is lowered by the parting member 65.

  Since the eaves-top support part 54 of the support bracket 51 is covered by the parting member 65, it can be avoided that the design of the eaves-top part is lowered by the support bracket 51.

[Other Embodiments]
The present invention is not limited to the description of the above embodiment, and may be implemented as follows, for example.

  (1) In the above embodiment, a step is generated between the pattern-less wall material 21A and the patterned wall material 21B depending on the presence or absence of the pattern formation layer 25, but the first wall material regardless of the presence or absence of the pattern formation layer 25. And a second wall surface material may have a step. For example, as shown in FIG. 5, a first wall surface member 81A and a second wall surface member 81B having a wall surface at a position protruding to the outdoor side from the first wall surface member 81A are arranged next to each other. A step is formed between the material 81A and the second wall surface material 81B.

  Moreover, the thickness dimension of the spacer member 71 may be adjusted according to the magnitude | size of the level | step difference between 81 A of 1st wall surface materials, and the 2nd wall surface material 81B. For example, in FIGS. 5B and 5C, the height D4a of the step between the first wall surface material 81A and the second wall surface material 81B is smaller than the thickness dimension D2 of the spacer member 71 and the first It is made the same as the thickness dimension D2a of the plate material 72. In this case, the outdoor side surface of the first plate member 72 is flush with the second wall member 81B by overlapping only the first plate member 72 on the first wall member 81A as a spacer member. For this reason, by superimposing the wall fixing portion 53 of the support bracket 51 on the first plate member 72, the positional relationship between the support bracket 51 and the eaves top plate 46 is changed to the support bracket 51 directly attached to the second wall surface member 81B. The positional relationship with the eaves top plate 46 can be made the same.

  Similarly, in FIGS. 5A and 5D, the height D4b of the step between the first wall surface member 81A and the second wall surface member 81B is the thickness dimension D2 of the spacer member 71 and the first plate member 72. It is smaller than the thickness dimension D2a and the same as the thickness dimension D2b of the second plate 73. In this case, by stacking only the second plate member 73 on the first wall surface member 81A as a spacer member, the outdoor side surface of the second plate member 73 is flush with the second wall surface member 81B. For this reason, the positional relationship between the support bracket 51 attached to the first wall surface member 81A and the eaves top plate 46 through only the second plate member 73 is set to the support bracket 51 directly attached to the second wall surface member 81B and the eave cover. The positional relationship with the plate 46 can be made the same.

  The first wall surface material 81A and the second wall surface material 81B may be formed in a thin plate shape by a ceramic siding board or the like. In this case, the base member 23 supporting the thin plate-like first wall surface material 81A and the second wall surface material 81B may be a long frame member. For example, FIGS. 5A and 5D show a configuration in which the first wall surface member 81A is formed in a thin plate shape, and the base member 23 supporting the first wall surface member 81A is a horizontally long frame member. 5 (b) and 5 (c) show a configuration in which the second wall surface member 81B is formed in a thin plate shape, and the base member 23 that supports the second wall surface member 81B is a horizontally long frame member. In the configuration in which one of the first wall material 81A and the second wall material 81B is formed in a thick plate shape and the other is formed in a thin plate shape, the back surfaces of these wall surface materials 81A and 81B are not flush with each other. May be.

  Furthermore, both the first wall surface material 81 </ b> A and the second wall surface material 81 </ b> B may have the pattern forming layer 25. In this case, the thickness dimension of the pattern forming layer 25 of the first wall surface material 81A is smaller than the thickness dimension of the pattern forming layer 25 of the pattern forming layer 25 of the second wall surface material 81B. The structure by which the wall surface is arrange | positioned in the position which protruded to the outdoor side rather than the wall surface of 81 A of 1st wall surface materials is realizable.

  (2) In the above embodiment, the spacer member 71 has the two plate members 72 and 73. However, the spacer member 71 may have one plate member or three or more plate members. Moreover, in the spacer member 71, the thickness dimension of the some board | plate materials 72 and 73 may be made the same.

  (3) In the above embodiment, the wall surface of the second wall surface member 81B is disposed as a second wall surface at a position protruding to the outdoor side from the second wall surface of the first wall surface material 81A. You may have a 1st wall surface material and a 2nd wall surface. For example, in one wall surface material having a partially protruding shape, a non-projecting portion forms a first wall surface and a protruding portion forms a second wall surface.

  (4) In the above embodiment, the eave ceiling support portion 54 of the support bracket 51 is covered with the parting member 65, but the eave ceiling support part 54 may not be covered with the parting member 65. For example, a parting member 65 in addition to the eaves top plate 46 is configured to enter the support groove 54 a of the eaves top support part 54.
