[Prior art]
In the construction of a house, it is required that a structure is provided so that rainwater does not enter the ridge, which is the top of the roof. In addition, since the ridge corresponds to the top of the house, it is desired that the ridge be constructed as light as possible without damaging the robust ridge structure.
FIG. 8 is a cross-sectional view showing the structure of a conventional building constructed without using mortar or ridge. In the conventional ridge shown in FIG. 8, a wooden plate member 101 is arranged on a roof member 103 on the roof top, and a ridge member 110 is placed and fixed thereon. That is, the wood 101 is used as a base material, and the ridge member 110 is supported by this.

[Problems to be solved by the invention]
However, in the conventional ridge shown in FIG. 8, almost the entire lower surface 101 a of the wood 101 is in close contact with the roofing material 103. In addition, the outer surface 101b and the upper surface 101c of the wood 101 are substantially in close contact with the inner surface of the ridge member 110.
In such a ridge, when rainwater enters the inside of the ridge member 110 from the eaves side of the roof, a capillary phenomenon occurs between the wood 101 and the roof material 103 or between the wood 101 and the ridge member 110. , Rainwater will rise to the top of the roof. The rainwater that has risen to the top of the roof corrodes the timber 101 and the field 102, and has a problem that the strength of the ridge structure is significantly reduced.
[0004]
If the members that make up the building are corroded or if the structure becomes brittle, the building may collapse.Therefore, it is necessary to periodically disassemble the building after construction, inspect / replace the members, and then reassemble. It is necessary and requires a great deal of labor after the construction. An object of the present invention is to provide a lightweight ridge member base material that improves the water resistance and durability of the ridge and reduces the need for maintenance.
