Description

  The present invention relates to a metal plate support bracket for supporting a lightweight and earthquake-resistant metal plate building.

Recently, as a ridge structure of a roof of a Japanese-style house, for example, a structure that is fixed using a ridge tile support bracket is known (see Patent Document 1 and Patent Document 2).
As shown in FIG. 7, for example, the support fitting 30 includes a pair of sheet metal support pieces 31 and 31 that are long in the vertical direction, and a pair of openings that are spread along the roof base plate. It consists of leg pieces 32, 32 and a U-shaped pedestal receiving portion 33 provided at the upper end. After the support fitting 30 is set on the ridge top 35 of the base plate 34, a pier 36 is attached to the pier receiving portion 33, and a ridge tile 40 is fixed to the pier 36 with nails or the like to form a ridge. In the figure, 37 is a mortar and 41 is a roof tile. Further, the roof tile 40 and the roof tile 41 are made of earthenware.

  Conventionally, as shown in FIG. 8, the wiping top portion 35 of the base plate 34 is filled with wiping soil 38, and a plurality of roof tiles 42 are stacked and fixed on both sides of the wiping soil 38. A ridge structure is also known in which a ridge tile 40 having an arc cross section is fixed on the ridge. Note that the roof tile 40, the roof tile 41, and the roof tile 42 are all made of earthenware.

  The building structure described above is Japanese-style and tasteful and popular. There was a problem of being inferior. In fact, it has been confirmed that there were many damages caused by the collapse of pottery tiles in the areas affected by the earthquake. In addition, it has been pointed out that the ceramic tile roofs are prone to cracking due to snow accumulation and the like, and the durability is poor.

  Therefore, it has been considered to replace the earthenware roof tile with a light, strong and inexpensive sheet metal building. However, in the Japanese-style roof building structure, it is not assumed that the sheet metal building is used, so it was not possible to simply replace the roof tile with the sheet metal building. In view of this, there has been a demand for the development of a new support member for a sheet metal building that can easily and reliably support the sheet metal building even in a Japanese-style roof building structure.
