Conventionally, as shown in Fig. 3, two roof surfaces A,
When applying a horizontal roof structure using horizontal roof plates made of thin metal sheets to a roof structure that has a valley C on both sides of B, the horizontal roof structure is applied on each roof surface A and B side. In addition to the normal horizontal roofing with boards, in the valley C, the ends of the horizontal roofing boards on each roof surface A and B are completely protected from rain, that is, in a state where there is no water leakage. It is necessary to connect them with good drainage.

Figure 4 shows each roof surface A, B for this valley C.
This figure shows the joint structure between the ends of the horizontal roof panels from the side, and the horizontal roof panels 1 and 2 using metal thin steel plates on the A and B sides of each roof are as follows:
While engaging and connecting the engaging parts 1a and 2a formed on the longitudinal side surfaces with each other, the roof is raised in accordance with the flow gradient on each roof surface A and B. Both end portions 1b and 2b of each horizontal roofing board 1 and 2 facing each other are individually covered for each row of horizontal roofing using end panels 1c and 2c formed in a predetermined shape. By doing this, the rainwater is treated, and at the same time, the concave groove part in the valley part C formed between both ends is also treated for each row of horizontal roofing using the receiving gutter 3 formed in a predetermined shape. They are constructed so that they can be laid down individually for drainage, and in the event of rain, the rainwater flowing into this valley C can be drained away through the receiving gutter 3.

[Problem that the invention seeks to solve]

However, in the case of the conventional example configured as described above, the valley C on the roof frame with poor work footing
As the roofing work in , for each row of horizontal roofing, each end surface is individually covered using end face plates 1c and 2c, and each end surface is individually covered in the concave groove between both end faces using a receiving gutter 3.
