  Here, in a configuration in which the bracket is attached at a position spaced downward from the upper end portion of the outer wall, the ink marking work is performed on the outer surface of the outer wall in order to position the eaves top plate. Brackets will be attached according to the height. However, there is a concern that the mounting accuracy of the bracket may be lowered due to the inking itself being shifted in the vertical direction or the mounting position of the bracket being shifted in the vertical direction with respect to the inking position. In addition, on the outer wall with irregularities formed on the outer surface for the purpose of improving the design, etc., the irregularities are obstructed, and the inking position and the bracket mounting position are likely to be displaced in the vertical direction. It will be remarkable.

  Further, in a configuration in which a plurality of brackets are arranged in parallel with the direction in which the eaves extend and the eaves top plate is supported by the brackets, if the height positions of the brackets vary and become uneven, the eaves are accordingly accompanied. The problem arises that the top plate is distorted.

  The main object of the present invention is to provide an eaves top plate support structure for a building that can appropriately attach the eaves top plate and facilitate the mounting work.

  Hereinafter, means and the like effective for solving the above-described problems will be described while showing functions and effects as necessary.

  The lower end portion of the vertical portion 55b of the extending portion 55 is connected to the open side end portion of the upper surface portion 54b of the support portion 54. In this case, the length of the upper surface portion 54b of the support portion 54 extending from the vertical portion 55b toward the outer wall 11 is smaller than that of the horizontal portion 55a of the extending portion 55, whereby the upper surface portion 54b. A gap is secured between the (support portion 54) and the outer wall 11.

  On the outer wall 11 side of the extension portion 55 and the support portion 54, an elastic deformation space S that allows the extension portion 55 to elastically deform toward the outer wall 11 side is formed. The elastic deformation space S is a space between the vertical portion 55b and the support portion 54 and the outer wall 11 below the horizontal portion 55a of the extending portion 55, and extends along the outer wall surface. In this case, the extending portion 55 can bend in a direction in which the support portion 54 is brought closer to the outer wall 11 as well as in a direction in which the support portion 54 is moved away from the outer wall 11.

  A parting member 65 is attached to the support portion 54 of the support bracket 51 and the outer wall side end portion of the eaves top plate 46. The parting member 65 has a cover part 65 a that covers the outer peripheral side of the support part 54 and the outer wall side end part of the eaves top plate 46, and an entry part 65 b that enters the recess of the support part 54. The parting member 65 is formed in a long shape from a synthetic resin material, and is provided so as to extend along the outer wall side end of the eaves top plate 46 (see FIG. 2). The cover part 65a is a decorative part that prevents the outer wall side end surfaces of the support part 54 and the eaves top plate 46 from being exposed below the eaves ceiling. The parting member 65 is separated from the outer wall 11 like the support portion 54.

  In the concave portion of the support portion 54, the entry portion 65 b enters between the eaves top plate 46 and the lower surface portion 54 c of the support portion 54. In this case, the eaves top plate 46 is placed on the lower surface portion 54c of the support portion 54 across the entry portion 65b of the parting member 65, and the entry portion 65b is placed on the lower surface portion 54c of the eaves top plate 46. It is a protective part that protects the part from being dented or damaged.

  The effective height dimension in the concave portion of the support portion 54, that is, the separation distance between the entering portion 65 b and the upper surface portion 54 b of the parting member 65 is substantially the same as the thickness dimension of the eave top plate 46. Is fitted to the support portion 54. In this case, the eaves top plate 46 is supported on the lower side by being placed on the lower surface part 54c, and not moved upward by contacting the upper surface part 54b. . That is, the eaves top plate 46 does not move in the vertical direction relative to the support portion 54.

  In addition, the effective height dimension in the recessed part of the support part 54 may be made smaller than the thickness dimension of the eaves top plate 46. Even in this case, the eaves top plate 46 can be fitted to the support portion 54 by elastically deforming the support portion 54 in the direction in which the upper surface portion 54b and the lower surface portion 54c are separated. In this case, the eaves top plate 46 can be reliably supported by the concave portion of the support portion 54. Further, the effective height dimension in the recess of the support portion 54 may be larger than the thickness dimension of the eaves top plate 46.

  The end surface of the eaves top plate 46 on the outer wall side is in contact with the side surface portion 54 a in the recess of the support portion 54. In this case, the eaves top plate 46 does not move relative to the support portion 54 toward the outer wall 11 side. In addition, in a state where the eaves top plate 46 enters the recess of the support portion 54, the extending portion 55 is elastically deformed, and the side surface portion 54 a is pressed (biased) toward the eave top plate 46 by the elastic force. ing. In this case, since the support portion 54 is pressed in the direction in which the overlapping dimension between the lower surface portion 54c and the eaves top plate 46 increases, the outer wall side end portion of the eaves top plate 46 does not come off from the lower surface portion 54c. It is like that.

  As shown in FIG. 2, a plurality of support brackets 51 are arranged at predetermined intervals along the upper end portion of the outer wall surface material 21 (the eaves of the roof portion 12). In this case, the height position of the lower surface portion 54c of the support portion 54 is the same in any of the support brackets 51, and the eaves top plate 46 placed on each lower surface portion 54c is kept horizontal without being bent. Will be.

  A plurality of eaves top plates 46 and parting members 65 are also arranged side by side along the direction in which the support brackets 51 are arranged. 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 65a of the parting member 65, and is connected to the parting member 65 by being bridged between the adjacent parting members 65.

  Next, a procedure for attaching the eaves top plate 46 below the eaves part 45 will be described with reference to FIG. FIG. 3 is a view for explaining the attachment procedure of the eaves top plate 46. In addition, in FIG. 3, illustration of the tile 33, the gutter 44, etc. is abbreviate | omitted.

  In the building 10, the outer wall 11 and the roof portion 12 are constructed before the eaves top plate 46 is attached. However, for the nose cover part 41 of the roof part 12, only the nose tip tree 42 of the nose tip tree 42 and the nose tip decorative plate 43 is attached.

  In the above state, first, as shown in FIG. 3A, the hooking portion 52 of the support bracket 51 is hooked on the upper end portion of the outer wall 11, and the hanging portion 53 is fixed to the outer wall surface material 21 and the base frame 22 with screws or the like. To do. In this case, since the support bracket 51 is simply hooked and held at the mounting position even if the operator does not hold it by hand, the worker easily performs the work of fixing the support bracket 51 with a screw or the like. be able to. The plurality of support brackets 51 are attached to the outer wall 11 by the same operation.

  Thereafter, as shown in FIG. 3B, the parting member 65 is attached to the support portion 54 of the support bracket 51. Here, a plurality of parting members 65 are attached to the support bracket 51, and the parting members 65 are connected by a connecting member 66.

  Then, as shown in FIG. 3C, the eaves top plate 46 is attached to the support part 54 and the nose cover part 41 of the support bracket 51. Here, the end on the outer wall side of the eaves top plate 46 is inserted into the recess of the support portion 54, and the end of the eaves top plate 46 is attached to the lower surface of the nose tip tree 42 with screws or the like. Thereafter, the nose tip decorative plate 43 is attached to the nose tip tree 42 and the eaves top plate 46. In this case, the operator does not need to fix the eaves side end of the eaves top plate 46 to the nose tip tree 42 with the other hand while supporting the outer wall side end of the eaves top plate 46 with one hand. The eaves-top 46 can be easily attached by one person. Thereby, it becomes possible to reduce the work man-hour in a construction site.

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

  In the support bracket 51, the height position of the support portion 54 is determined by the hook portion 52 being hooked on the upper end portion of the outer wall 11. It is possible to suppress the protruding position and the mounting position of the support bracket 51 from shifting up and down. Moreover, since the support bracket 51 hangs down from the upper end portion of the outer wall 11, the height of the support portion 54 can be achieved by the support bracket 51 straddling a plurality of unevenness even if the outer surface of the outer wall 11 is uneven. It can suppress that a position shifts to the up-down direction or the left-right direction. Therefore, it is possible to prevent the mounting heights of the plurality of support brackets 51 from becoming uneven, and consequently to prevent the eaves top plate 46 supported by the support brackets 51 from being distorted. As described above, the eaves top plate 46 can be properly attached and the attaching operation can be facilitated.

  In the support bracket 51, since the elastic deformation space S is secured on the outer wall 11 side of the support portion 54 and the extension portion 55, the support portion 54 together with the eaves top plate 46 is attached to the outer wall 11 along with the elastic deformation of the extension portion 55. It is possible to move both in the direction of approaching and the direction of moving away from the outer wall 11. For this reason, when the building 10 is shaken, it becomes possible to displace the support portion 54 in accordance with the shake of the eaves top plate 46, and the outer wall side end of the eaves top plate 46 is detached from the support portion 54. It is possible to suppress the top plate 46 from being strongly pressed by the support portion 54 to be deformed or damaged. Further, even if the eaves of the roof portion 12 sways relatively with respect to the outer wall 11, the eaves top plate 46 can be prevented from being deformed or damaged by the stress of the sway. Therefore, the eaves top plate 46 can be properly supported by the support portion 54 even if the building 10 is shaken.

  Since the outer wall side end portion of the eaves top plate 46 is separated from the outer wall 11 via the support portion 54, unlike the configuration in which the support portion 54 is fixed to the outer wall 11, the eave sky Separation and contact between the outer wall side end of the plate 46 and the outer wall 11 are not repeated. Therefore, it is possible to avoid the eaves top plate 46 and the outer wall 11 from being deformed or damaged due to repeated separation and contact.

  In the support bracket 51, the hanging part 53 is fixed to the outer wall 11, so that even if the elastic deformation space S is formed on the outer wall 11 side of the extension part 55, the support bracket 51 supports and stabilizes the eaves top plate 46. Can be achieved. Thereby, even if the building 10 is shaken, in the configuration in which the eaves top plate 46 can be properly supported by the support portion 54, only the eaves top plate 46 is shaken by wind or the like even though the building 10 is not shaken. Can be suppressed.

  In the configuration in which the upper surface of the lower surface portion 54c of the support portion 54 is the mounting surface of the eaves top plate 46, the lower surface portion 54c is pressed toward the eaves top plate 46 by the elastic deformation of the extending portion 55. The support portion 54 is difficult to move in a direction away from the outer wall side end portion of the eaves top plate 46. Thereby, it can suppress that the outer wall side edge part of the eaves top board 46 remove | deviates from the lower surface part 54c.

  Since the outer wall side end portion of the eaves top plate 46 enters the recess of the support portion 54 from the eaves side, it is possible to prevent the outer wall side end portion of the eaves top plate 46 from separating upward from the support portion 54. Thereby, even if the eaves top board 46 shakes up and down with the shaking of the building 10, it can suppress that the outer wall side edge part of the eaves top board 46 comes off from the recessed part of the support part 54. FIG.

  Since the lower surface portion 54 c of the support portion 54 of the support bracket 51 and the eaves top plate 46 are parallel to each other, the lower surface portion 54 c is inclined with respect to the eaves top plate 46. It is difficult for deformation and damage to occur on the portion placed on the lower surface portion 54c.

  Since the support portion 54 of the support bracket 51 and the outer wall 11 are separated from each other, the outer wall side end of the eaves top plate 46 and the outer wall 11 are also separated. In this case, it is possible to ventilate the ceiling space of the eaves ceiling or the attic space through the gap between the eaves top plate 46 and the outer wall 11.

  In the support bracket 51, the back side portion 52 b of the hook portion 52 is hooked on the back surface of the outer wall surface material 21, so that the hook portion 52 is hooked only on the upper end surface of the outer wall surface material 21. It is difficult for the support bracket 51 to be detached from the upper end portion of the outer wall 11. Moreover, since the back side portion 52b of the hooking portion 52 is hooked on the horizontal frame material 26a of the base frame 22 that supports the outer wall surface material 21, the support strength of the support bracket 51 can be suitably ensured. The support strength of 46 can be suitably secured.

  Since the support bracket 51 is formed by bending a thin plate, the upper end portion of the outer wall 11 can be changed by changing the bending position of the extending portion 55 with respect to the hanging portion 53 or the bending position of the supporting portion 54 with respect to the extending portion 55. The height dimension of the support portion 54 with respect to can be easily adjusted.

[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, the height positions of the eaves side end and the outer wall side end in the eaves top plate 46 are the same, but the height positions of the eaves side end and the outer wall side end are May be different. For example, as shown in FIG. 4, the eaves top plate 46 is provided so as to be inclined so that the end part on the eaves side is lower than the end part on the outer wall side. In this configuration, in the support bracket 51, the horizontal portion 55a of the extending portion 55 extends obliquely downward from the hanging portion 53, so that the opening direction of the concave portion of the support portion 54 is inclined downward. Thereby, even if the eaves top plate 46 is inclined, it is possible to insert the outer wall side end portion of the eaves top plate 46 into the recess of the support portion 54.

  The configuration in which the opening side of the concave portion of the support portion 54 is directed obliquely downward is not limited to the configuration in which the angle of the horizontal portion 55a with respect to the hanging portion 53 is increased as described above, and the vertical portion with respect to the horizontal portion 55a in the extending portion 55. Examples include a configuration in which the angle of the portion 55b is reduced, and a configuration in which the angle of the upper surface portion 54b with respect to the vertical portion 55b is reduced.

  In addition, in the configuration in which the eaves top plate 46 is provided so as to be inclined so that the end part on the eaves side is higher than the end part on the outer wall side, the open side of the concave portion of the support part 54 is directed obliquely upward. It is preferable.

  (2) In the above-described embodiment, in the support bracket 51, the extended portion 55 is connected to the open end of the upper surface portion 54b of the support portion 54. However, the extended portion 55 is connected to any portion of the upper surface portion 54b. It only has to be connected. For example, as shown in FIG. 5A, the extension portion 55 may be connected to an intermediate portion of the upper surface portion 54b, and as shown in FIG. 5B, the closed side end portion ( It may be connected to the outer wall side end). Further, as shown in FIG. 5C, the support portion 54 may be a plate-like portion protruding from the extending side end portion of the extending portion 55 instead of the U-shaped portion.

  Moreover, the extension part 55 should just be a shape which can ensure the elastic deformation space S in the outer wall 11 side of the extension part 55 and the support part 54. As shown in FIG. For example, as shown in FIG. 5B, the extension portion 55 may extend linearly downward obliquely, and as shown in FIG. It may extend. Incidentally, when the extending portion 55 extends in a curve, the extending portion 55 may be curved toward either the upper side or the lower side. Further, in the above embodiment, only one bent portion in the extending portion 55 is provided at the boundary portion between the horizontal portion 55a and the vertical portion 55b, but a plurality of bent portions may be provided.

  In the support bracket 51, the extending portion 55 may not be provided. That is, the support portion 54 may be provided at the lower end portion of the hanging portion 53. In this case, the support portion 54 comes into contact with the outer wall 11, but even in this configuration, the end portion on the outer wall side of the eaves top plate 46 can be supported by the support portion 54.

  (3) The hooking portion 52 of the support bracket 51 may not be hooked on the horizontal frame member 26 a of the base frame 22. That is, the outer wall surface material 21 and the horizontal frame material 26a may be hooked only on the outer wall surface material 21. In short, the hook portion 52 only needs to be hooked on the upper end portion of the outer wall 11.

  Further, the hook portion 52 of the support bracket 51 may not be provided with the back side portion 52b. Even in this case, the hook portion 52 can be hooked on the upper end surface of the outer wall 11 by the upper portion 52a.

  (4) The support bracket 51 may be configured such that at least one of the horizontal portion 55a and the vertical portion 55b in the extending portion 55 can be elastically deformed. Even in this configuration, it is possible to realize a configuration in which the support portion 54 is displaced in accordance with the swing of the eaves top plate 46 when the swing of the building 10 occurs.

  (5) In the concave portion of the support portion 54 of the support bracket 51, the eaves top plate 46 may be placed directly on the lower surface portion 54c without sandwiching the entry portion 65b of the parting member 65. In this case, the parting member 65 which does not have the entering part 65b may be attached to the support part 54 and the eaves top plate 46, and the parting member 65 itself may not be attached.

  (6) The support portion 54 of the support bracket 51 may be supported by hanging from above instead of supporting the outer wall side end of the eaves top plate 46 from below. For example, the eaves top plate 46 is disposed below the lower surface portion 54 c of the support portion 54, and screws are screwed to the lower surface portion 54 c from the eave top plate 46 side, whereby the eave top plate is attached to the support portion 54. 46 is fixed.

  (7) The eaves top plate 46 supported on the outer wall 11 by the support bracket 51 may be bridged between the windbreak plate and the outer wall 11 instead of the nose cover part 41. In this case, the roof portion 12 constitutes a gable roof, and the eaves top plate 46 is provided below the ribs.

  (8) For example, as shown in FIG. 6, in the configuration in which the angle jig 71 is attached to the upper end surface of the outer wall surface material 21, the support bracket 51 is arranged so that the upper end surface of the hanging portion 53 is the angle jig 71. You may attach to the position contact | abutted to the lower end surface of. Even in this case, it is possible to easily determine the height position of the support bracket 51 without performing the marking operation. In addition, after attaching the support bracket 51, the other end of the eaves top plate 46 is fixed to the nose cover with one end of the eaves top plate 46 inserted into the recess of the support portion 54 of the support bracket 51. The top plate 46 can be attached alone. In this configuration, the hooking portion 52 is not provided on the support bracket 51.

  A flat portion 72 whose outer surface does not have irregularities is formed at the upper end portion of the outer wall surface material 21, and the angle jig 71 is attached to the outer surface of the flat portion 72. For this reason, even if the angle jig 71 is not hooked on the upper end of the outer wall 11, it is possible to prevent the mounting height of the angle jig 71 from being shifted due to the unevenness of the outer wall surface material 21. By the way, in the outer wall surface material 21, the flat portion 72 has an outer surface recessed toward the indoor side, and the thickness dimension is made smaller than other portions.

  As shown in FIG. 7, when the shaft support portion 73 that pivotally supports the eaves top plate 46 is attached to the outer surface of the outer wall surface material 21, the eaves top side end portion of the eaves top plate 46 is covered with the nose cover portion 41. Even if the eaves top plate 46 is not fixed to the eaves top plate 46, the eaves end side end portion and the outer wall side end portion can be set at the same height position. In addition, the angle of inclination of the eaves top plate 46 can be changed by rotating the eaves top plate 46. In this case, the inclination angle of the eaves top plate 46 can be changed flexibly, and various exterior designs of the building 10 can be supported.

  Moreover, even if the shaft support 73 and the eaves top plate 46 are attached to the outer wall 11 in the factory, the outer wall 11 is moved to a parallel position parallel to the outer wall material 21 by rotating the eave top plate 46. When the unit is transported to the construction site, the eaves top plate 46 can be prevented from hindering transport. In this case, even if the window portion 75 is formed below the shaft support portion 73, the eave top plate 46 is rotated during transportation by rotating the eave top plate 46 toward the upper side opposite to the window portion 75. Interference with the window 75 can also be avoided.

  Further, a ventilation gap is formed between the outer wall side end of the eaves top plate 46 and the outer wall 11, and it is possible to ventilate the ceiling space of the eaves ceiling and the attic space through the ventilation gap. It has become.
