At that time, when there is no outer wall 44, the fixing bolt 7 is supported by one or both of the side edges 41b and 42b, and the front bolt hole 41a and the rear bolt hole 42a are pushed outward. It may be spread out to cause problems such as deformation and breakage of the vertical frame 4. On the other hand, in this embodiment, since the stress received from the fixing bolt 7 can be dispersed and supported by the inner wall surface 48, it is possible to suppress problems such as further movement and deformation of the vertical frame 4. Can do.

  It is preferable that the side end edges 41b and 42b of the front bolt hole 41a and the rear bolt hole 42a are formed substantially flush with the inner wall surface 48 of the outer wall 44 as described above. When the hole 42a is formed by punching or the like, the position of the side edge 41b, 42b is located on the center side of the vertical frame 4 from the inner wall surface 48, and the inner wall surface 48 and the side edge 41b, 42b As a result, a step (not shown) is formed. When the stepped portion is generated, when the eaves panel 2 as described above receives wind, the stepped portion is crushed by the fixing bolt 7 until it is substantially flush with the inner wall surface 48. Therefore, if the height of the stepped portion is too large, a problem may occur. Even when the stepped portion is formed, the height dimension is preferably short, and the thickness of the front side wall 41 or the rear side wall 42 is further preferable. Shorter than the dimension is more preferable.

In this embodiment, a side piece 49 extending in the vertical direction is provided outside the outer wall 44 of the vertical frame 4. Thereby, when the above-mentioned eaves panel 2 receives a wind, the deformation | transformation which the outer side wall 44 of the vertical frame 4 expands outside by the fixing bolt 7 can be suppressed. In this embodiment, the side piece 49 is

The front side wall 41 and the rear side wall 42 are formed so as to face each other with the outer side wall interposed therebetween, that is, they are formed to be flush with the outer wall surface of the front side wall 41 or the rear side wall 42. . As a result, the effect is further enhanced, and the front bolt hole 41a hole and the rear bolt hole 42a due to the fixing bolt 7 can be prevented from spreading toward the outside of the outer wall 44.

  Further, when the vertical frame 4 and the vertical frame fixing portion 62 are fastened using the fixing bolt 7, the washer W is disposed over the outer wall surface of the rear side wall 42 and the outer wall surface of the rear side piece 49. For example, the front side wall 41 or the rear side wall 42 can be firmly fastened without unnecessarily narrowing the interval.

  In addition, as shown in FIG. 10, the effect can be further enhanced by providing a thick portion 49a with the base end portion of the side piece 49 being thicker.
