2. Description of the Related Art For connecting a metal horizontal thatched roof structure in a standard length method (horizontal direction), a roof plate and a roof plate (see FIG. 8) described in Japanese Utility Model Publication No. 59-15523 are used. There are those in which the wasteboard is formed integrally, and those in which the wasteboard and the roofing board are formed separately, such as those described in Japanese Utility Model Publication No. 61-65122.

By the way, the metal roof plate expands and contracts due to a temperature change according to its own coefficient of expansion. Specifically, as indicated by an arrow in FIG. 9, the metal roof plate extends from the center to the outside along the longitudinal direction. To expand and contract.

Regarding this point, like the former one, the connection state is such that the insertion piece 52 is simply inserted into the insertion part 51, and like the latter one, the side edge of the wasteboard is engaged. In the connection structure in which the engaging portion of the roof plate side edge portion is engaged with the receiving portion so as to be hooked, the connection is disconnected when the roof plate 50 expands and contracts due to temperature change (Fig. 8 (state shown by imaginary line), there is a problem that distortion cannot occur because expansion and contraction cannot be permitted.

Further, these problems also cause water leakage.

As described above, the conventional products described above are not designed in consideration of the dislocation and distortion due to thermal expansion and contraction, and no effective countermeasure is taken for this point.

[0007]

The problem to be solved is to apply a negative pressure (roof) to the roof plate when the roof plate thermally expands and contracts.
Pressure such as wind pressure that tries to lift the plate upward) or positive pressure
For (pressure such as the pedaling pressure applied from above the roof),
The point is that the disconnection of the connection part of the rootboard and the water leakage related to it cannot be prevented.
