この表に示された通り、接合用下地材を適用した試験体においては、これを適用しないものに比較して非常に大きな有効性を示している。
とりわけ、１乃至４の部位の結果が明確に両者の相違を明示していることが解る。
As shown in this table, the test body to which the bonding base material is applied shows a very large effectiveness as compared with a specimen to which this is not applied.
In particular, it can be seen that the results for sites 1 to 4 clearly indicate the difference between the two.
以上説明した通り、本発明に係る接着鋼板からなる接合用下地材を適用した下地壁構造体においては、それを適用しない下地壁構造体に比較して格段の強度を有するものであり、壁体ボードの接合部位の変位が極めて少なく、ボード及びクロスのクラック等をも極めて少ないものとすることができたものである。 As described above, in the base wall structure to which the base material for bonding made of the adhesive steel plate according to the present invention is applied, the base wall structure has a remarkable strength as compared with the base wall structure to which the base material is not applied. The displacement of the bonding portion of the board is extremely small, and the cracks of the board and the cloth can be extremely small.
