Thereby, the part which needs reinforcement can be reinforced suitably. In this case, the through-hole 4 and the carbon fiber sheet 14 are disposed at a portion where the bundle 13 of carbon fiber strands is attached.

  Further, the shaft reinforcing member 11 may protrude from the side end faces 1c and 1d as long as it is a portion that does not detract from the appearance of the brick wall 1 in a state of being inserted into the through hole 12.
