The rainwater can reach the upper surface of the piece 54 through the top surface of the face material 50 and the holding portion 51a by the piece 54, and the rainwater can be appropriately guided to the groove 20a from the tip.

  According to the roof structure 1 as described above, the column main body 11 has a so-called H-shaped cross section and has a pair of grooves 11d and 11e that open in opposite directions. It becomes possible to insert and fix members constituting the roof such as girders. This eliminates the need for an intermediate member interposed when connecting the support column and the structural member for the portion, thereby reducing the number of parts and assembly man-hours.

  The drainage is as follows. As described above, horizontal ridges (horizontal ridges) are formed by the grooves 20a whose cross section appears in FIG. For example, when rainwater flows toward the support column 10 as indicated by A in FIG. 3 by the groove 20a, the support column 10 can function as a vertical shaft. That is, the rainwater flowing through the groove 20a reaches the upper end of the support column 10, and if a drainage hole or gap leading to the hollow inside of the central covering material 13b (see FIG. 5) is provided here, the central covering material 13b Since water falls inside the hollow, it can be used as a vertical gutter. Therefore, an additional downpipe is not required, and the number of parts and the number of assembly steps can be further reduced. Further, according to this, even when drainage is passed through the support column 10, it is possible to take out the drainage from the central covering material and lead it to an external drainage facility without opening a drainage port such as a hole in the support column body 11. It is.

  In the present embodiment, an example has been described in which the column body is fixed by enclosing the ends of the girders in a pair of grooves formed by having an H-shaped cross section. However, the present invention is not limited to this, and some other member constituting the roof structure may be included in the groove and fixed. For example, the above-described beam may be inserted into the groove portion of the column main body and fixed by a fixing member. This eliminates the need for the column-side fixing bracket 15.
