However, in this case, since the high-strength fiber sheet 3 is not bonded to the other side surface 1c of the foundation 1, the reinforcing band plate 4 is directly fixed to the other side surface 1c.

（第４の実施の形態）
図５は本発明に係る基礎の補強構造の第４例を示すものである。この図に示す基礎１、土台２は第１の実施の形態における基礎１、土台２と同様の構成である。
本例では、第１および第３の実施の形態と同様に、高強度繊維シート３は、土台２の上面２ａおよび両側面２ｂ，２ｂと、基礎１の両側面１ｃ，１ｃとを覆うようにして、土台２の上方から被され、基礎１の両側面１ｃ，１ｃ、土台２の両側面２ｂ，２ｂ、土台２の上面２ａに接着剤によって接着されている。 (Fourth embodiment)
FIG. 5 shows a fourth example of the foundation reinforcing structure according to the present invention. The foundation 1 and the foundation 2 shown in this figure have the same configuration as the foundation 1 and the foundation 2 in the first embodiment.
In this example, as in the first and third embodiments, the high-strength fiber sheet 3 covers the upper surface 2a and both side surfaces 2b, 2b of the base 2 and the both side surfaces 1c, 1c of the foundation 1. The base 2 is covered from above, and is bonded to both side surfaces 1c and 1c of the base 1, both side surfaces 2b and 2b of the base 2, and the upper surface 2a of the base 2 with an adhesive.

また、基礎１の両側面１ｃ，１ｃの上端部および下端部に、それぞれ金属製の矩形板状の補強板７が前記高強度繊維シート３上から基礎の長手方向に沿って所定間隔で固定されている。この固定は、図３に示す第３の実施の形態の場合と同様にして、挿通ボルト５とナット６によって行われる。   In addition, metal rectangular plate-like reinforcing plates 7 are fixed at predetermined intervals along the longitudinal direction of the foundation from above the high-strength fiber sheet 3 to the upper and lower ends of both side surfaces 1c, 1c of the foundation 1, respectively. ing. This fixing is performed by the insertion bolt 5 and the nut 6 as in the case of the third embodiment shown in FIG.

本実施の形態によれば、基礎１の側面１ｃ，１ｃの上端部および下端部に、補強板７が高強度繊維シート３上から基礎１の長手方向に沿って所定間隔で固定されているので、例えば土台２に固定する柱を基礎１に連結するための連結金具を補強板７に固定する場合に、この部分を効果的に補強できる。
なお、本実施の形態においても、図４（ａ）〜（ｃ）に示すような、パターンの変形例を採用してもよい。
すなわち、基礎１の一方の側面１ｃ、土台２の一方の側面２ｂ、土台２の上面２ａに、高強度繊維シート３を接着したものにおいて、補強板７を基礎１の両側面１ｃ，１ｃに固定してもよい。但し、この場合、基礎１の他方の側面１ｃには高強度繊維シート３が接着されていないので、他方の側面１ｃには補強板７が直接固定される。
また、基礎１の両側面１ｃ，１ｃ、土台２の両側面２ｂ，２ｂ、土台２の上面２ａに、高強度繊維シート３を接着したものにおいて、補強板７側面２ｂの下端部にのみ固定してもよい。
さらに、基礎１の一方の側面１ｃ、土台２の一方の側面２ｂ、土台２の上面２ａに、高強度繊維シート３を接着したものにおいて、補強板７を側面２ｂの下端部にのみ固定してもよい。但し、この場合、基礎１の他方の側面１ｃには高強度繊維シート３が接着されていないので、他方の側面１ｃには補強板７が直接固定される。 According to the present embodiment, the reinforcing plate 7 is fixed to the upper and lower ends of the side surfaces 1c, 1c of the foundation 1 at predetermined intervals along the longitudinal direction of the foundation 1 from above the high-strength fiber sheet 3. For example, when a connecting metal fitting for connecting a pillar fixed to the base 2 to the foundation 1 is fixed to the reinforcing plate 7, this portion can be effectively reinforced.
Also in the present embodiment, pattern variations as shown in FIGS. 4A to 4C may be adopted.
That is, the reinforcing plate 7 is fixed to the both side surfaces 1c and 1c of the foundation 1 when the high strength fiber sheet 3 is bonded to one side surface 1c of the foundation 1, one side surface 2b of the foundation 2 and the upper surface 2a of the foundation 2. May be. However, in this case, since the high-strength fiber sheet 3 is not bonded to the other side surface 1c of the foundation 1, the reinforcing plate 7 is directly fixed to the other side surface 1c.
Further, in the case where the high strength fiber sheet 3 is bonded to the both side surfaces 1c and 1c of the foundation 1, the both side surfaces 2b and 2b of the base 2, and the upper surface 2a of the base 2, it is fixed only to the lower end portion of the side surface 2b of the reinforcing plate 7. May be.
Further, in the case where the high-strength fiber sheet 3 is bonded to the one side surface 1c of the foundation 1, the one side surface 2b of the base 2, and the upper surface 2a of the base 2, the reinforcing plate 7 is fixed only to the lower end portion of the side surface 2b. Also good. However, in this case, since the high-strength fiber sheet 3 is not bonded to the other side surface 1c of the foundation 1, the reinforcing plate 7 is directly fixed to the other side surface 1c.
