A mounting plate 41 was provided along the wall surface of the outer wall portion 15, and the eaves portion 18 was attached to the eaves mounting portion 48 of the mounting plate 41. In this case, the upper end of the mounting plate 41 was inserted into the upper gap 38 provided in the outer wall portion 15 and fixed to the outer wall portion 15 in the inserted state. As a result, even if an excessive load (impact) is applied to the eaves 18 due to snowfall on the eaves 18, it is possible to prevent the mounting plate 41 from falling off from the outer wall 15, and as a result, the eaves It is possible to prevent the 18 from falling off from the outer wall portion 15.

Further, when a load is applied on the eaves 18, the mounting plate 41 tends to tilt to the outdoor side. Therefore, the mounting plate 41 is inserted into the upper gap 38 with the upper end of the mounting plate 41 inserted into the outer wall portion 15. It is particularly effective to fix the mounting plate 41 to the mounting plate 41 in order to prevent the mounting plate 41 from falling off.

Specifically, regarding the mounting plate 41, in addition to inserting the upper end portion into the upper gap 38, the lower end portion thereof is inserted into the lower gap 39 provided in the outer wall portion 15, and the mounting plate 41 is inserted in the inserted state. It was fixed to the outer wall portion 15. In this case, the attachment plate 41 can be further suppressed from falling off from the outer wall portion 15, and as a result, the eaves portion 18 can be further suppressed from falling off from the outer wall portion 15.

Further, by fixing the mounting plate 41 to the outer wall portion 15 with the mounting plate 41 inserted into the gaps 38 and 39, the screw 42 fixing the mounting plate 41 to the outer wall portion 15 may be temporarily damaged by the impact of falling snow. Also, it is possible to prevent the mounting plate 41 from falling off from the outer wall portion 15.

Further, it is conceivable to prevent the mounting plate 41 from falling off by increasing the number of screws 42 for fixing the mounting plate 41 to the outer wall portion 15, but according to the above configuration, the number of screws 42 is not increased. It is possible to prevent the eaves 18 from falling off.

A plurality of mounting plates 41 were provided at predetermined intervals in the wall width direction (width direction of the outer wall portion 15), and the eaves 18 were attached to the eaves mounting portions 48 of each of the mounting plates 41. In such a configuration, the upper gap 38 and the lower gap 39 are each elongated in the wall width direction, and the outer wall portion is in a state where the mounting plates 41 are inserted into the gaps 38 and 39, respectively. It was fixed at 15. In this case, when the mounting plate 41 is mounted on the outer wall portion 15, the mounting plate 41 can be slid to a predetermined mounting position along the wall width direction with the mounting plate 41 inserted in the gaps 38 and 39. .. Further, since each mounting plate 41 is inserted into the same lower gap 39, the height position of each mounting plate 41 naturally becomes the same height position, and as a result, the height position of each mounting plate 41 is set during the mounting work. The work of matching can be eliminated. Therefore, in this case, the configuration is such that a plurality of mounting plates 41 are provided, and the mounting work of the mounting plate 41 on the outer wall portion 15 can be facilitated.

Further, in the above configuration, since the mounting position of each mounting plate 41 can be changed in the wall width direction, the distance between the mounting plates 41 can be freely set. Therefore, when it is desired to change the distance between the support arms 54 according to the type (size, etc.) of the eaves 18, it becomes easy to deal with the situation.

By the way, in the conventional configuration in which the eaves portion 18 is directly attached to the outer wall frame 23 of the outer wall portion 15, it is assumed that the outer wall surface material 22 cannot be provided within the installation height range in which the eaves portion 18 is installed. In that case, the fire resistance may deteriorate in the installation height range of the eaves 18. In that respect, in the above embodiment, the outer wall surface material 22b is provided at the same height position as the eaves portion 18, the mounting plate 41 is provided on the outdoor side surface of the outer wall surface material 22b, and the mounting plate 41 is attached to the outer wall surface by the screw 42. It was fixed to the entrance frame 23a via the material 22b. Therefore, the eaves portion 18 can be attached to the eaves attachment portion 48 while ensuring the fire resistance performance. Further, even in the configuration in which the mounting plate 41 is fixed to the entrance frame 23a via the outer wall surface material 22b in this way, the upper end portion of the mounting plate 41 is the facing plate portion 33b of the horizontal frame material 33 and the outer wall surface material 22b. Since it is inserted into the upper gap 38 between the mounting plate 41 and the eaves portion 18, it is possible to prevent the mounting plate 41 from falling off.

The screw 42 was driven into the horizontal frame material 31 of the entrance frame 23a via the facing plate portion 33b of the horizontal frame material 33, the mounting plate 41, and the outer wall surface material 22b. Further, the screw 42 was driven into the horizontal frame material 32 of the entrance frame 23a via the facing plate portion 34b of the horizontal frame material 34, the mounting plate 41, and the outer wall surface material 22b. As a result, the portions of the mounting plate 41 inserted into the gaps 38 and 39 are firmly fixed in a state of being sandwiched between the facing plate portions 33b and 34b and the outer wall surface material 22b, respectively, so that the mounting plate 41 It is possible to further suppress the dropout of.

A portion (specifically, the horizontal plate portion 33a and the portion extending from the facing plate portion 33b to the back surface side of the outer wall material 22c through the inter-wall gap 36 between the outer wall materials 22b and 22c adjacent to the upper and lower sides of the horizontal frame member 33. A portion composed of a stacking plate portion 33c) was provided. In this case, since the inter-wall gap 36 can be closed by the portion, the fire resistance performance of the inter-wall gap 36 can be improved by using the horizontal frame material 33 forming the upper gap 38.

Since the horizontal frame material 33 is provided with a laminated plate portion 33c that is overlapped on the back surface of the outer wall material 22c and the outer wall material 22c is fixed, the horizontal frame material 33 can also be used as a fixing base for the outer wall material 22c. Further effective use of the frame material 33 can be achieved.

In the rectangular frame-shaped entrance frame 23a, the horizontal frame members 33 and 34 forming the gaps 38 and 39 were bridged and fixed to the pair of vertical frame members 24 extending vertically. In this case, since the horizontal frame materials 33 and 34 can be integrated with the entrance frame 23a in advance at the manufacturing factory, the horizontal frame materials 33 and 34 can be predetermined by installing the entrance frame 23a at the construction site. Can be placed in position. Therefore, it is possible to obtain the above-mentioned effects by the horizontal frame materials 33 and 34 while reducing the man-hours at the construction site.

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

(1) In the above embodiment, the horizontal frame materials 33 and 34 are provided on both the upper and lower sides of the outer wall surface material 22b, respectively, but among the horizontal frame materials 33 and 34, the lower horizontal frame material 34 is not used. It may be provided and only the upper horizontal frame material 33 may be provided. In this case, of the upper gap 38 and the lower gap 39, only the upper gap 38 is formed. Even in such a configuration, by fixing the mounting plate 41 to the outer wall portion 15 with the upper end portion of the mounting plate 41 inserted into the upper gap 38, it is possible to prevent the mounting plate 41 from falling off from the outer wall portion 15. As a result, it is possible to prevent the eaves portion 18 from falling off from the outer wall portion 15.

(2) In the above embodiment, the outer wall surface material 22b is provided at the same height position as the eaves portion 18, but the outer wall surface material 22b may not be provided. In this case, for example, the gap (corresponding to the upper insertion portion) between the facing plate portion 33b of the horizontal frame material 33 and the horizontal frame material 31 (specifically, the flange portion 31a) and the facing plate portion 34b and the lateral side of the horizontal frame material 34. It is conceivable that the gap (corresponding to the lower insertion portion) between the frame material 32 (specifically, the flange portion 32a) is the same as the thickness of the mounting plate 41. Then, it is conceivable that the upper and lower ends of the mounting plate 41 are inserted into the respective gaps, and the mounting plate 41 is fixed to the horizontal frame members 31 and 32 in the inserted state. However, in order to ensure the fire resistance, it is desirable to provide the outer wall surface material 22b as in the above embodiment.

(3) In the above embodiment, the upper gap 38 and the lower gap 39 (upper insertion portion and lower insertion portion) are formed by using the elongated horizontal frame members 33 and 34. These gaps (upper insertion portion and lower insertion portion) may be formed by using a short member. For example, it is conceivable to provide the entrance frame 23a with a short member having the same cross-sectional shape as the horizontal frame material 33 instead of the upper horizontal frame material 33. In this case, it is conceivable that the short member is provided only at the arrangement position of each mounting plate 41 in the wall width direction and is fixed to, for example, the horizontal frame member 31. In this case, the short member corresponds to the member on the wall.

Further, similarly to this, the entrance frame 23a may be provided with a short member having the same cross-sectional shape as the horizontal frame material 34 instead of the lower horizontal frame material 34. In this case as well, it is conceivable that the short member is provided only at the arrangement position of each mounting plate 41 in the wall width direction and is fixed to, for example, the horizontal frame member 32. In this case, the short member corresponds to the under-wall member.

(4) In the above embodiment, the upper insertion portion (where the upper end portion of the mounting plate 41 is inserted) is formed by the upper gap 38 between the facing plate portion 33b of the horizontal frame material 33 and the outer wall surface material 22b. The upper insertion portion does not necessarily have to be formed by such a gap 38. For example, it is conceivable that the horizontal frame material 33 does not have the facing plate portion 33b, and instead, an insertion member made of a steel plate having a U-shaped cross section is provided on the lower surface of the horizontal plate portion 33a of the horizontal frame material 33. In this case, the insertion member has an elongated shape extending in the longitudinal direction of the horizontal frame member 33, and is fixed to the lower surface of the horizontal plate portion 33a with the groove portion facing downward. Then, it is conceivable to insert the upper end portion of the mounting plate 41 into the groove portion of the insertion member. In this case, the groove portion of the insertion member corresponds to the upper insertion portion.

Further, similarly to this, the lower insertion portion may be formed by the groove portion of the insertion member instead of being formed by the lower gap 39.

(5) In the above embodiment, two mounting plates 41 are provided, but three or more mounting plates 41 may be provided. In short, the number of mounting plates 41 may be appropriately adjusted according to the number of each support arm 54 of the eaves portion 18.

Further, only one mounting plate 41 may be provided. For example, it is conceivable to provide one mounting plate 41 extending in the width direction of the eaves 18. In this case, it is conceivable that a plurality of eaves mounting portions 48 are provided on the mounting plate 41 at predetermined intervals along the longitudinal direction, and the support arm 54 is fixed to each of the eaves mounting portions 48.

It is not always necessary to fix the support arm 54 to the eaves mounting portion 48 of the mounting plate 41, and members other than the support arm 54 in the eaves portion 18 may be fixed. For example, the eaves portion 18 may be separately provided with an arm member extending in the width direction of the eaves portion 18 between the support arms 54, and the arm member may be fixed to the eaves attachment portion 48.

(6) In the above embodiment, the support arm 54 (specifically, the fixing plate 57) is fixed to the eaves mounting portion 48 (corresponding to the mounting portion) of the mounting plate 41, but the mounting plate 41 is not provided with the eaves mounting portion 48. The support arm 54 may be directly fixed to the mounting plate 41. In that case, the portion of the mounting plate 41 to which the support arm 54 is fixed (mounted) corresponds to the "mounting portion".

(7) In the above embodiment, the mounting plate 41 is driven into the horizontal frame materials 31 and 32 via the mounting plate 41 and the outer wall surface material 22b by driving the screw 42 (corresponding to the fixture) into the horizontal frame materials 31 and 32, respectively. However, a fixture other than the screw 42 may be used to fix the mounting plate 41. For example, bolts or tapping screws may be used as the fixture. In that case, the mounting plate 41 is screwed into the horizontal frame materials 31 and 32 (specifically, the screw holes of the horizontal frame materials 31 and 32) via the mounting plate 41 and the outer wall surface material 22b, so that the mounting plate 41 is screwed into the horizontal frame materials 31. , 32 will be fixed.
