Further, in another embodiment shown in FIG. 4, the pair of opposing suspender members (21), (21) are interposed between the pair of suspender base members (3]), (31). directly without letting it happen.

Since it is fixedly mounted on the lower shedding board (52), it can produce the same functions and effects as those of the embodiment shown in FIGS. 1 and 2.

(Effects of the Invention) As described in detail above, according to the present invention, the left and right engaging plate portions having both side edges bent downward on the face plate portion of the roof plate member;
and a locking protrusion is provided on the lower end edge thereof, and a support part raised from the mounting part and a hanger pressure contact part which is bent downward are attached to the pair of opposing suspender members. A pair of suspender base members are provided, the lower end of which is used as a locking edge, and a pair of hanger base members having a supporting portion are provided, and the groove forming member is further provided with a substrate groove portion and left and right side wall portions extending upward from both side edges of the substrate groove portion. , and a butt part made by bending each side wall part inward, and a joining pressure part made by bending this part downward.As a result, each pair of hanger stand members can be placed on the lower roofing board. are attached at predetermined intervals, and a groove forming member is arranged between them, and each suspender base member is attached to the support part, and each pair of suspender members is attached with the mounting part facing each other. By mounting, the abutment part and the joint pressure contact part of the groove forming member are supported in pressure contact with the inside of the support part of each hanger member and the hanger pressure contact part, and the adjacent attachments are straddled between the mounting parts. With the upper field board placed,
In this state, by fitting the roof board member including the support part of each hanger member onto the upper sheathing board, the engagement plate part of the roof board member is pressed and supported by the hanger pressure contact part of each hanger member. Then, the locking protrusion can be hooked to the locking edge, and this can be done in the same way even when no hanger base member is interposed at the bottom of each hanger member. In this way, a desired roof structure can be constructed through the water drainage openings between adjacent roof sheet members and the groove forming members inside the openings.

In addition, the roof structure configured in this way not only effectively eliminates the effects of strong wind and rain on the roof surface, but also allows for relatively large slits between adjacent roof plate members. Since the water drain is formed with an open L1 portion, rainwater can be drained well. From the outside, the face plate side edge of the roof plate member and the engagement plate part are pressed together, and from the inside, the abutting part of the groove forming member and the joint pressure welding part are pressed independently. The roof plate member and the groove forming member can be strongly held separately, so that even if a force is applied to both members, there is no risk of the force being applied to the other member, and at the same time, the locking edge of the hanger member Since the locking protrusion of the roof plate member is locked, these members can be firmly connected as a whole, and the structure is relatively simple and can be provided easily and inexpensively. It has several features.
