A roof joint structure in which the upper and lower surfaces of a deformable joint body are fixed, or a roof joint structure in which the joint body is separable and fixed into an upper joint body and a lower joint body in the joint body having the above configuration. By doing this, it is possible to prevent rainwater from entering the joint and to absorb thermal expansion and contraction of the roof board,

It can be constructed by simply providing the joint body 6 between the roofing structure and the roofing structure, and has the advantage that the roofing can be completed in an extremely short time without requiring a high degree of skill or experience.

Furthermore, the joint body 6 can be fixed in advance to the back side of the connecting joint part 4 of the roof board A or the above water side of the main plate 1 with an adhesive or the like, and by doing so, the workability is further improved. can be done.

Next, in the invention of claim 2, in the joint body 6 in the invention of claim 1, the upper joint body 6a,
By fixing it separably to the lower joint body 6b,
The upper joint body 6a can be fixed to the lower surface of the connecting joint part 4, and the lower joint body 6b can be fixed to the water side of the main plate 1 in advance at a factory or the like.

The upper joint body 6a is on the water side.

Since the lower joint bodies 6b are provided separately, the upper joint body 6a and the lower joint body 6b made of the same material can be fixed to each other, and in particular, thermal welding can be easily performed, making layer roofing work easier. be.

Furthermore, since the other structure of the invention of claim 2 is a consultation with the structure of the invention of claim 1, it can exhibit the same effect as the structure of the invention of claim 1.

In addition, as shown in FIGS. 6 and 7, the joint body 6 is provided with grooves 6.
By forming C, the deformation of the joint body 6 can be facilitated and increased, and thermal expansion and contraction of the roof panel A can be better coped with.
