Description
また、第1発明〜第4発明によれば、凹部及び凸部と壁高欄の壁面との間の段差空間に、発泡ポリスチレンフォーム等のあらかじめ形状の定まった中詰材が設けられるため、あらかじめ形状の定まっていない液体のモルタルや樹脂等の経時硬化性材料を段差空間に設ける場合のような、経時硬化性材料の硬化のための硬化時間を必要としないものとなって、壁高欄を補強するための施工期間を短期化させることが可能となる。
さらに、第1発明〜第4発明によれば、発泡ポリスチレンフォーム等の中詰材が段差空間に設けられるため、段差空間にモルタルや樹脂等の経時硬化性材料が設けられる場合と比較して、壁高欄の面外方向への変位を発泡ポリスチレンフォーム等の塑性変形で吸収し易いものとして、地震等による壁高欄の倒壊を確実に防止することが可能となる。
