FIG. 2 is an exploded perspective view showing a supporting structure of the eaves top plate 36 with respect to the outer wall 11. FIG. 3 is an enlarged vertical sectional view showing a support structure of the eaves top plate 36 with respect to the outer wall 11.

  As shown in FIGS. 2 and 3, a support metal 41 supporting the eaves top plate 36 is attached to the outer wall 11. The support metal 41 is formed of a steel plate in an L-shape and fixed to the outer surface of the outer wall surface material 17 by a screw 43 and the eaves tip side from the lower end of the fixed plate 41a (opposite to the outer wall 11) And an extending plate portion 41b extending toward the side). In the extension plate portion 41b, the extension length (length in the thickness direction of the outer wall 11) is longer than the vertical length of the fixed plate portion 41a. However, the extension length of the extension plate portion 41b may be the same length as the vertical length of the fixed plate portion 41a. The screw 43 penetrates the fixed plate portion 41 a and the outer wall surface material 17 and is driven into the base frame 18. Further, in this case, the support metal 41 corresponds to the support member.

  A plurality of support hardware 41 are arranged at predetermined intervals along the wall width direction of the outer wall 11 (in other words, along the outer wall side end 36 a of the eaves top plate 36). A parting material 42 is attached to the support hardware 41. The parting material 42 has a long shape extending in the wall width direction of the outer wall 11, and is made of, for example, a synthetic resin material. The parting material 42 is provided straddling the support hardwares 41 and is attached to the support hardwares 41 respectively. The parting material 42 does not necessarily have to be formed of a synthetic resin material, and may be formed of another material such as a metal material (for example, a steel plate).

  The parting material 42 is a decorative material for covering the outer wall side end 36 a of the eaves top plate 36 from the outer wall 11 side, and is attached to the outer wall side end 36 a of the eaves top plate 36. In this case, the eaves top plate 36 is in a state of being attached to each support metal 41 via the parting material 42, and thus in a state of being attached to the outer wall 11 via the parting material 42 and each support metal 41. Further, in the mounting state of the eaves top plate 36, the outer wall side end portion 36 a is separated from the outer wall 11.

  The parting material 42 has a first groove 45 opened to the eaves end side (the opposite outer wall 11 side) and a second groove 46 opened to the outer wall 11 side. The outer wall side end 36 a of the eaves top plate 36 is inserted into the first groove 45 from the eaves tip side. In this inserted state, the parting material 42 is attached to the outer wall side end 36a.

  In the second groove portion 46, the extension plate portions 41b of the support hardwares 41 are inserted from the outer wall 11 side. The extension plate portion 41 b of each of the support hardwares 41 is inserted to the deepest portion of the second groove portion 46. In this case, in the inserted state, the parting material 42 is attached to the extension plate portion 41 b of each support hardware 41. Further, in the attached state of the parting member 42, the parting member 42 is separated from the outer wall 11. For this reason, a predetermined gap S is formed between the outer wall 11 and the parting material 42. The gap S is used as a ventilation gap or the like for ventilating the space above the eaves top plate 36 (the eaves space).

  The second groove 46 is located below the first groove 45. Therefore, the outer wall side end 36a of the eaves top plate 36 inserted in the first groove 45 is supported from below by the extension plate 41b of each support metal 41 inserted in the second groove 46. ing. That is, in this case, the outer wall side end portion 36 a of the eaves top plate 36 is supported by the supporting hardware 41 via the parting material 42.

  Subsequently, the configuration of the parting material 42 will be described in detail.

  The parting material 42 is formed in a long and plate shape by extrusion molding of a resin material. In this case, the parting member 42 has the same cross section (cross section in the direction perpendicular to the longitudinal direction) throughout the longitudinal direction. The parting material 42 has a plurality of plates 51 to 53 forming the second groove 46. In each of the plate portions 51 to 53, a pair of opposing plate portions 51 and 52 facing each other vertically across the second groove portion 46, and the eaves end of the opposing plate portions 51 and 52 are vertically connected. A connecting plate portion 53 is included. The distance between the opposing plate portions 51 and 52, that is, the groove width of the second groove portion 46 is set to the same size as the thickness of the support metal 41 (the extension plate portion 41b). For this reason, in a state in which the extension plate portion 41 b of the support metal 41 is inserted into the second groove portion 46, the extension plate portion 41 b is in a state of being fitted with the second groove portion 46. The groove width of the second groove 46 does not have to be the same as the thickness of the support 41, and may be slightly smaller or larger than the thickness of the support 41. Further, among the opposing plate portions 51 and 52, the opposing plate portion 51 is positioned on the lower side, and the opposing plate portion 52 is positioned on the upper side.

  In this parting material 42, a plurality of types (specifically, two types) of eaves top plates 36 having different thicknesses can be inserted into the first groove 45, so that the parting material 42 can be used as the respective eaves 36 It is possible to attach to each. Therefore, in the following, the configuration regarding that point will be described.

  The parting material 42 further includes a plurality of plates 54 and 55 that form the first groove 45 together with the opposing plate 52 in addition to the plates 51 to 53 described above. In each of the plate portions 54, 55, the opposing plate portion 54 which is vertically opposed with the opposing plate portion 52 and the first groove portion 45 interposed therebetween, and the end portions of the opposing plate portions 52, 54 on the outer wall 11 side are vertically arranged. A connecting plate portion 55 is included.

  Among the plate portions 52, 54, 55 forming the first groove portion 45, the opposing plate portion 52 is a horizontal plate portion extending horizontally in the thickness direction of the outer wall 11, and is disposed below the first groove portion 45. It is done. The opposing plate portion 52 is disposed between the first groove 45 and the second groove 46, and divides the grooves 45 and 46 into upper and lower portions.

  The opposing plate portion 54 extends in the thickness direction of the outer wall 11 and is disposed on the upper side of the first groove portion 45. The length of the opposing plate portion 54 in the thickness direction is the same as the length of the opposing plate portion 52 in the same direction. In this case, each of the opposing plate portions 52 and 54 corresponds to “a pair of opposing plate portions opposing each other in the vertical direction across the groove portion” described in the claims. Further, the opposing plate portion 52 corresponds to the “lower opposing plate portion”, and the opposing plate portion 54 corresponds to the “upper opposing plate portion”.

  The opposing plate portion 54 includes a back side plate portion 54a extending from the upper end portion of the connecting plate portion 55 toward the eaves end, a step plate portion 54b extending short upward from the eaves tip side end portion of the back side plate portion 54a, And a front side plate portion 54c extending from the upper end portion of the step plate portion 54b toward the eaves end. The back side plate portion 54 a and the front side plate portion 54 c are both horizontal plate portions parallel to the opposing plate portion 52.

  The first groove portion 45 has a near side portion 61 between the opposing plate portion 52 and the near side plate portion 54c, and a far side portion 62 between the opposing plate portion 52 and the far side plate portion 54a. In this case, the groove width of the first groove portion 45 (the distance between the opposing plate portions 52 and 54) is smaller in the rear side portion 62 than in the front side portion 61. That is, the groove width L2 of the back side portion 62 (the distance between the opposite plate portion 52 and the back side plate portion 54a) than the groove width L1 of the front side portion 61 (the distance between the opposite plate portion 52 and the front side plate portion 54c). Is smaller (L1> L2). In this case, the near side portion 61 corresponds to the "first portion", and the far side portion 62 corresponds to the "second portion".

  The step plate portion 54 b is located at the central portion of the opposing plate portion 54 in the thickness direction of the outer wall 11. Therefore, the front side plate portion 54c and the rear side plate portion 54a connected via the step difference plate portion 54b have the same length in the thickness direction. Further, the groove width L2 of the back side portion 62 is smaller than the groove width L1 of the front side portion 61 by the provision of the step plate portion 54b. In more detail, by providing the step plate portion 54b, a step having a dimension (L1-L2) is generated between the front side plate portion 54c and the back side plate portion 54a. The stepped plate portion 54b corresponds to a stepped portion.

  Next, the configuration of the attachment state in which the above-mentioned parting member 42 is attached to the eaves top plate 36 will be described. In the following, when the parting material 42 is attached to a thick eaves top plate 36 (hereinafter, A is attached to its code) and to a small eaves top plate 36 (hereinafter, B is attached to its code) Each case will be described. In FIG. 3, (a) shows a state in which the parting material 42 is attached to the thick eaves 36A, and in (b), the parting material 42 is attached to the small eaves 36B. It shows the state. Further, here, the thickness t1 of the eaves top plate 36A is set to the same size as the groove width L1 of the front side portion 61 of the first groove portion 45 of the parting material 42 (t1 = L1), and the thickness of the eaves top plate 36B It is assumed that t2 is set to the same size as the groove width L2 of the back side portion 62 of the first groove 45 (t2 = L2).

  The thickness t1 of the eaves top plate 36A does not necessarily have to be the same as the groove width L1 of the front side portion 61, and may be set slightly smaller or slightly larger than the groove width L1 of the front side portion 61. Similarly, the thickness t2 of the eaves top plate 36B may be set slightly smaller or slightly larger than the groove width L2 of the back side portion 62.

  First, the case where the parting material 42 is attached to the thick eaves 36A will be described. In FIG. 3A, the outer wall side end 36a of the eaves top plate 36A is inserted into the first groove 45 of the parting material 42. In this case, the outer wall side end portion 36a of the eaves top plate 36A is inserted into the front side portion 61 of the first groove 45 and abuts against the step plate portion 54b of the parting material 42 in the inserted state. Further, the outer wall side end 36a of the eaves top plate 36A is engaged with the near side portion 61 in this inserted state. Thereby, the parting material 42 is attached with respect to the outer wall side edge part 36a of the eaves top plate 36A.

  Then, the case where the parting material 42 is attached to the small eaves 36B of thickness is demonstrated. In FIG. 3B, the outer wall side end 36a of the eaves top plate 36B is inserted into the first groove 45 of the parting material 42. In this case, the outer wall side end 36a of the eaves top plate 36B is inserted into the back side portion 62 through the front side portion 61 of the first groove 45 and abuts on the connecting plate 55 in the inserted state. Further, the outer wall side end 36a of the eaves top plate 36B is engaged with the back side portion 62 in this inserted state. Thereby, the parting material 42 is attached with respect to the outer wall side edge part 36a of the eaves top plate 36B.

  Here, the operation procedure at the time of constructing the parting structure of the eaves top plate 36 mentioned above is demonstrated easily.

  In order to construct the parting structure, first, each support hardware 41 is fixed to the outer wall 11 with a screw 43. After that, an operation of attaching the parting material 42 to each of the support hardwares 41 is performed. This mounting operation is performed by inserting the extension plate portions 41 b of the support hardwares 41 into the second groove portions 46 of the parting member 42.

  Next, an operation of attaching the eaves top plate 36 to the see-through material 42 is performed. This mounting operation is performed by inserting the first outer wall portion 36 a of the eaves top plate 36 into the first groove 45 of the cutting member 42. At this time, if the eaves top plate 36 is a thick eaves top plate 36A, the eaves top plate 36A is inserted until it abuts on the step plate portion 54b. On the other hand, when the eaves top plate 36 is a small eaves top plate 36B, the eaves top plate 36B is inserted until it abuts on the connecting plate portion 55. Specifically, at this time, first, the outer wall side end portion 36a of the eaves top plate 36B is placed on the opposing plate portion 52, and the eaves top plate 36B is directed toward the back side of the first groove 45 in the placed state. I will. Thus, the parting structure of the eaves top plate 36 is constructed. In addition, the installation operation of the eaves top plate 36 is completed by attaching the eaves-end side edge part of the eaves top plate 36 to the lower surface of the nose tip tree 32 etc. after said operation | work.

  According to the configuration of the embodiment described above, the following excellent effects can be obtained.

  The first groove portion 45 of the parting material 42 has a front side portion 61 on the groove opening side and a rear side portion 62 which is deeper than the front side portion 61 and smaller in groove width than the front side portion 61 It was composition. Therefore, as described above, by inserting the eaves top plate 36A having a large thickness (specifically, the outer wall side end 36a thereof) into the front side portion 61 of the first groove 45, the parting material 42 is the eaves top plate 36A. It is possible to attach to Further, by inserting the eaves top plate 36B (specifically, the outer wall side end portion 36a thereof) having a small thickness into the deep side portion 62 of the first groove 45, the parting material 42 can be attached to the eaves top plate 36B. It has become. Thereby, it becomes possible to attach the parting material 42 to two types of eaves top plates 36A and 36B from which thickness differs, As a result, it becomes possible to suppress that the kind of parting material increases.

  The groove width L2 of the back side portion 62 is greater than the groove width L1 of the front side portion 61 in the opposing plate portion 54 among the opposing plate portions 52 and 54 facing up and down with the first groove portion 45 in the parting member 42 While the step plate portion 54b to be made smaller is provided, the opposite plate portion 52 is not provided with such a step plate portion. Thus, when the outer wall side end portion 36a of the eaves top plate 36B having a small thickness is inserted into the rear side portion 62 of the first groove portion 45, the outer wall side end portion 36a is formed along the upper surface of the opposing plate portion 52. It can be inserted while inserting. Therefore, at the time of the insertion, the outer wall side end 36 a can be inserted relatively easily to the back side portion 62 without being hooked to the step plate portion.

  Specifically, the stepped plate portion 54 b is provided on the upper opposed plate portion 54 of the opposed plate portions 52 and 54, and the stepped plate portion is not provided on the lower opposed plate portion 52. In this case, when the eaves top plate 36B having a small thickness is inserted into the back side portion 62 of the first groove 45, first, the outer wall side end 36a of the eaves top plate 36B is placed on the opposing plate 52 and the outer wall in that state It becomes possible to insert the side end 36 a up to the back side portion 62. This makes it possible to more easily insert the eaves top plate 36B into the back side portion 62.

  In addition to the first groove 45, the second groove 46 opened toward the outer wall 11 is provided below the first groove 45 in the parting member 42. And each support metal 41 fixed to the outer wall 11 is made into L shape which has the fixing | fixed plate part 41a and the extension board part 41b, and the extension board part 41b of these each support metal 41 is inserted in the 2nd groove part 46, respectively. I did. And it was set as the structure which attaches the parting material 42 to each support hardware 41 by the insertion. In this case, the support metal 41 is formed in a simple L-shape, and the extension plate portion 41b of the support metal 41 is covered from the lower side by the facing plate portion 51) of the parting material 42. Thus, the configuration of supporting the eaves top plate 36 can suppress loss of the appearance due to the support metal 41 while obtaining effects such as cost reduction.

  The present invention is not limited to the above embodiment, and may be implemented, for example, as follows.

  In the above embodiment, the parting members 42 can be attached to the two types of eaves 36A and 36B having different thicknesses, but may be attachable to the three or more eaves 36 having different thicknesses. For example, in the case where the parting material 42 can be attached to three types of eaves top plates 36 having different thicknesses, the first groove 45 of the parting material 42 may be a first part on the groove opening side and a groove part deeper than the first part. The second part of the side and the third part of the groove back side of the second part are formed, and the groove widths of the first to third parts are the groove width of the first part> the groove of the second part It may be formed such that the width> the groove width of the third portion.

  In the above embodiment, the step plate portion 54b is provided on the upper opposing plate portion 54 of the opposing plate portions 52 and 54 facing up and down with the first groove portion 45, and the step plate portion 54b is applied to the lower opposing plate portion 52. Although the stepped plate portion is not provided, this may be reversed. That is, the lower opposing plate portion 52 may be provided with the stepped plate portion, and the upper opposing plate portion 54 may not be provided with the stepped plate portion. Specifically, the lower side plate portion 52 is a back side plate portion extending from the lower end portion of the connecting plate portion 55 to the eaves end, a step plate portion extending downward from the eaves tip side end portion of the back side plate portion, And a front side plate portion extending from the lower end portion of the step plate portion to the eaves end side. Further, the upper opposing plate portion 54 is a horizontal plate portion extending horizontally in the thickness direction of the outer wall 11. In this configuration, the space between the front side plate portion of the opposing plate portion 52 and the opposing plate portion 54 is the near side portion (corresponding to the first portion), and the space between the back side plate portion of the opposing plate portion 52 and the opposing plate portion 54 is It becomes the back side part (equivalent to the second part). And the groove width of the back side part becomes smaller than the groove width of the near side part. Therefore, also in this case, it is possible to attach the parting members 42 to the eaves 36A and 36B having different thicknesses. Further, since the upper opposing plate portion 54 is not provided with the step plate portion, when the eaves top plate 36B having a small thickness is inserted into the back side portion of the first groove portion 45, the outer wall side end of the eaves top plate 36B It becomes possible to insert the portion 36 a along the lower surface of the opposing plate portion 54. Therefore, the eaves top plate 36B can be inserted relatively easily to the back side portion without being hooked on the step plate portion.

  In addition, you may make it provide a level | step-difference board part in both of each opposing board part 52 and 54, respectively. In that case, the step plate portions of the opposing plate portions 52 and 54 may be set at the same position in the thickness direction of the outer wall 11. However, in this case, when the eaves top plate 36B having a small thickness is inserted into the back side portion, the eaves top plate 36B may be caught on the step portions of the opposing plate portions 52, 54, making it difficult to insert. Therefore, in view of this point, it is desirable to provide the stepped plate portion only on one of the opposing plate portions 52 and 54.

  -Although the shape of the support metal 41 was made into L shape in the said embodiment, the shape of the support metal 41 is not necessarily restricted to this. For example, it has a hooking portion capable of hooking the support metal on the upper end of the outer wall 11, a hanging portion hanging from the hooking portion along the outer surface of the outer wall 11, and an extending plate portion extending from the hanging portion to the eaves end It is conceivable to configure. Also in this case, if the extension plate portion is inserted into the second groove 46 of the parting material 42, it becomes possible to attach the parting material to the support metal.

  In the above embodiment, the second groove 46 is provided in the parting member 42, and the parting member 42 is attached to the supporting member 41 by inserting the extension plate portion 41b of the supporting member 41 in the second groove 46. You may change this. For example, the parting material 42 is provided with a fixing plate part fixed to a part of the support metal 41 with a screw or the like, and the parting material 42 is attached to the part 41 by fixing the fixing plate part to the part.
