As shown in the figure, when constructing the roof structure 1, the base plate portions 10 of the supporting members 7 are placed on the ground 4 at each of the locations where the two supporting members 7 are installed (see FIG. 6A). A recess 4A is formed in advance at a location on the ground 4 where the base plate portion 10 is placed. The recessed portion 4A is a recess with a depth corresponding to the thickness of the base plate portion 10. The base plate part 10 is placed in the recess 4A of the ground 4 from above, and a part or the whole of the base plate part 10 in the thickness direction (vertical direction) is arranged in the recess 4A.

Next, each of the two supporting members 7 fixes the supporting column 5 to the supporting column fixing portion 11 of the supporting member 7 protruding from the base plate portion 10 (see FIG. 6B). At this time, the lower end portion 5A of the column 5 is fixed to the column fixing portion 11, and the fixing material 9 is attached to the lower end portion 5A of the column 5. Subsequently, the dirt floor concrete 3 is placed on the ground 4 and the base plate portion 10 of the support member 7, and the base plate portion 10 is buried between the ground 4 and the dirt floor concrete 3 (see FIG. 6C). Thereby, the base plate part 10 is sandwiched between the ground 4 and the concrete floor 3 and buried in the installation location 2 of the roof structure 1.

The base plate part 10 is placed on the upper surface of the ground 4, and is sandwiched between the upper surface of the ground 4 and the lower surface of the concrete floor 3, and is placed between the upper surface of the ground 4 and the lower surface of the concrete floor 3. buried in between. The lower end 5A of the pillar 5 and the lower part 11A of the pillar fixing part 11 are located below the floor surface 3A of the concrete floor 3, and the part above the lower end 5A of the pillar 5 and the lower part 11A of the pillar fixing part 11 are located below the floor surface 3A of the concrete floor 3.

Thereby, the support material 7 can be firmly fixed to the dirt floor concrete 3, and the support material 7 can be stably supported by the dirt floor concrete 3. By burying the lower end portion 5A of the column 5 in the dirt floor concrete 3, the lower end portion 5A of the column 5 can be fixed to the dirt floor concrete 3 while being fixed to the column fixing portion 11 of the support member 7. Therefore, the lower end portion 5A of the support column 5 can be supported by the concrete floor 3. By fixing the fixing material 9 protruding from the lower end portion 5A of the column 5 to the dirt floor concrete 3, the strength of fixing the lower end portion 5A of the column 5 to the dirt floor concrete 3 can be increased. Therefore, the lower end portion 5A of the support column 5 can be stably supported by the earthen floor concrete 3.

When installing the support column 5 at a position near the periphery of the installation location 2 of the roof structure 1, it is conceivable that the base plate portion 10 of the support member 7 protrudes from the periphery of the installation location 2 to the outside of the installation location 2.
