It is possible to suppress the decrease in the degree of freedom in the installation of equipment.

The connecting member of the flat roof equipment installation structure according to the second aspect extends in an orthogonal direction orthogonal to the height direction and the inside / outside direction, and the insertion portion is spaced apart from the connecting member in the orthogonal direction. Multiple pieces are formed at the same time.

In the equipment installation structure of the flat roof according to the second aspect, a plurality of insertion portions are formed in the extending direction of the connecting member. Therefore, the length of the connecting member from the equipment to one insertion part can be compared with the length of the connecting member from the equipment to the other insertion part, and the shorter one can be selected. It is possible to suppress the increase in length.

Between the wall material and the cap tree member of the equipment installation structure of the flat roof according to the third aspect, a limiting member that comes into contact with the connecting member and restricts the infiltration of liquid is provided.

In the equipment installation structure of the flat roof according to the third aspect, since the limiting member limits the infiltration of the liquid between the wall material located on the upstream side of the insertion portion and the cap tree member, the liquid passes through the insertion portion. It is possible to prevent infiltration into the room.

For these reasons, in the parapet structure 40, it is possible to suppress the degree of freedom in installing the solar panel unit 30 on the flat roof 22 from being lowered as compared with the configuration in which another structure is provided for drawing in the wiring 36. can.

In addition, in the parapet structure 40, the wiring 36 of each solar panel unit 30 is not integrated in one place, but is inserted into the insertion portion 48 at the nearest place. As a result, the length of the wiring 36 required for one solar panel unit 30 can be shortened as compared with the configuration in which the wiring 36 of each solar panel unit 30 is integrated in one place. ..

Further, in the parapet structure 40 shown in FIG. 3, a plurality of insertion portions 48 are formed in the extending direction of the upper frame member 44. Therefore, the length of the wiring 36 from the solar panel unit 30 to the insertion portion 48 is compared with the length of the wiring 36 from the solar panel unit 30 to the other insertion portion 48, whichever is shorter. You can choose. As a result, it is possible to prevent the length of the wiring 36 from becoming longer as compared with the configuration in which the insertion portion 48 is formed only at one location.

Further, in the parapet structure 40 shown in FIG. 2, the rubber material 52 is a liquid (for example, water) between the siding material 42 and the cap tree member 46 located upstream of the insertion portion 48 in the routing direction of the wiring 36. ) Is restricted. That is, since the liquid from the flat roof 22 toward the insertion portion 48 is restricted by the rubber material 52, it is possible to prevent the liquid from entering the room through the insertion portion 48.
