The upper part support member 2 includes: an upper part foundation part 20 which includes an upper part through hole 22 through which the bolt 4 penetrates, and which is fixed to the upper surface of the beam material B; and upper part arch support parts 21 which extend obliquely upward to both sides of a position to sandwich the upper part foundation part 20, and which support upper arch members. The lower part support member 3 includes: a lower part foundation part 30 which includes a lower part through hole 33 through which the bolt 4 penetrates, and which is fixed to the lower surface of the beam material B; lower part arch support parts 31 which extend obliquely upward to both sides of a position to sandwich the lower part foundation part 30, and which support lower arch members; and arm parts 32 which support the lower part arch support parts 31 at positions separated from the lower part foundation part 30 at a predetermined distance.
