[0023] A method for installing a roofing material and a rainproof roof structure for plant cultivation according to one embodiment of the present invention will be described below. FIG. 1 is a conceptual diagram showing a rain protection roof structure for plant cultivation according to this embodiment, where FIG. 1(a) is a side view of the rain protection roof structure for plant cultivation, and FIG. 1(b) is a perspective view of the rain protection roof structure for plant cultivation.

[0024] In the field, a first ridge 10 and a second ridge 20 are formed on either side of a main passage A, with the first ridge 10 being formed between the main passage A and a first sub-passage B, and the second ridge 20 being formed between the main passage A and a second sub-passage C. A first ridge board 11 is provided on the main passage A side of the first ridge 10, and a second ridge board 21 is provided on the main passage A side of the second ridge 20. The first ridge 10 and second ridge 20 in Figure 1 show ridges formed by a frame-board high ridge cultivation method in which a ridge board is used on only one side of the ridge, but ridge boards may also be used on both sides of the ridge. The frame-type raised ridge cultivation method is used for growing asparagus. For example, the ridge height is 40 to 60 cm, the top base is 50 cm, and the bottom base is at least twice the height of the top base. Asparagus is planted in the center of the top base. The main passage A is protected from rain and is used as a work space and a passage for transporting equipment. It is wider than the first sub-passage B and the second sub-passage C, with a width of 150cm to 220cm.

[0025] In the roof material installation method according to this embodiment, the first pillar material 31 is erected along the first ridge board 11, the second pillar material 32 is erected along the second ridge board 21, and the beam material 40 is connected to the first pillar material 31 and the second pillar material 32. The lower ends of the first pillars 31 and the second pillars 32 are buried in the ground. The beams 40 connect the first pillars 31 and the second pillars 32 at their upper positions and are installed horizontally in a direction that intersects with the passage direction of the main passage A as shown in the figure. In this way, by erecting the first post 31 along the first ridge board 11 and erecting the second post 32 along the second ridge board 21, the first post 31 functions as a retainer for the first ridge board 11, and the second post 32 functions as a retainer for the second ridge board 21, and the first post 31 can be stably erected by the first ridge board 11, and the second post 32 can be stably erected by the second ridge board 21. Furthermore, according to this embodiment, the first post 31 and the second post 32 are connected by the beams 40, and therefore the gate-shaped structure formed by the first post 31, the second post 32, and the beams 40 is sandwiched between the first ridge board 11 and the second ridge board 21, which increases resistance, especially to crosswinds.

Girder 76 is placed on top of second diagonal member 52, and girder 77 is placed below second diagonal member 52.

[0029] In this way, according to the roof material installation method of this embodiment, the rain protection roof structure for plant cultivation of this embodiment can be obtained. The rain protection roof structure for plant cultivation according to this embodiment has a first pillar 31 erected along the first ridge board 11, a second pillar 32 erected along the second ridge board 21, a beam 40 connected to the first pillar 31 and the second pillar 32, a first diagonal member 51 connected to the first pillar 31, the second pillar 32 and the beam 40, and a second diagonal member 52 connected to the second pillar 32 and the beam 40, and the first diagonal member 51 is The second pillar material 32 side is positioned higher above the first ridge 10 and the main passage A, and the second diagonal material 52 is positioned higher above the second ridge 20 with the second pillar material 32 side, and the first roof material 61 is positioned on the first roof surface formed by the multiple first diagonal materials 51 arranged along the main passage A, and the second roof material 62 is positioned on the second roof surface formed by the multiple second diagonal materials 52 arranged along the main passage A.

[0030] In this way, by erecting the first post 31 along the first ridge board 11 and erecting the second post 32 along the second ridge board 21, the first post 31 functions as a retainer for the first ridge board 11, and the second post 32 functions as a retainer for the second ridge board 21, and the first post 31 can be stably erected by the first ridge board 11, and the second post 32 can be stably erected by the second ridge board 21. Furthermore, according to this embodiment, the first post 31 and the second post 32 are connected by the beams 40, and therefore the gate-shaped structure formed by the first post 31, the second post 32, and the beams 40 is sandwiched between the first ridge board 11 and the second ridge board 21, which increases resistance, especially to crosswinds.

[0031] In addition, in the rain protection roof structure for plant cultivation according to this embodiment, the lower end 61d of the first roof material 61 is positioned above the first sub-passage B, and the lower end 62d of the second roof material 62 is positioned above the second sub-passage C. Therefore, according to this embodiment, rainwater flowing down from the first roofing material 61 is guided to the first sub-passage B, and rainwater flowing down from the second roofing material 62 is guided to the second sub-passage C, thereby utilizing the rainwater to prevent the first ridge 10 and the second ridge 20 from drying out. In addition, in the rain protection roof structure for plant cultivation according to this embodiment, the heights of the first roof material upper end 61u of the first roof material 61 and the second roof material upper end 62u of the second roof material 62 are made different, so that a ventilation opening is formed between the first roof material upper end 61u and the second roof material upper end 62u. Therefore, according to this embodiment, the rising heat can be discharged and ventilation can be improved, so that the temperature rise caused by installing the roof material can be suppressed.
