ANCHOR BOLT, WASHER, AND FOAM BUILDING MATERIAL
To obtain good strength, waterproofness, moisture resistance, heat insulation, sound insulation, etc., by sufficiently foaming in a short time.SOLUTION: A foaming body 130 is provided on a sleeve 120, and the foaming body 130 is foamed by energizing between the sleeve 120 and an anchor bolt 100 by utilizing an insulating washer 140, whereby a gap between the anchor bolt 100 and an embedding hole 152 is filled with foaming resin. Thus, foaming can be sufficiently performed in a short time, the joining strength between the anchor bolt 100 and concrete 150 is improved, water hardly enters the embedding hole 152, and waterproofness and moisture resistance are improved. For example, it is possible to satisfactorily prevent deterioration of rust quality and the deterioration of service life due to the water gushing out from a bedrock or a hot spring water in tunnel construction or the like.SELECTED DRAWING: Figure 1
【課題】 短時間で十分に発泡を行って、良好な強度や、防水性，耐湿性，断熱性，遮音性等を得る。【解決手段】 スリーブ１２０に発泡体１３０を設けるとともに、絶縁ワッシャー１４０を利用してスリーブ１２０とアンカーボルト１００との間に通電して発泡体１３０を発泡させ、これにより、アンカーボルト１００と埋め込み穴１５２との隙間に発泡樹脂を充填する。これにより、短時間で十分に発泡を行うことができ、アンカーボルト１００とコンクリート１５０との間の接合強度が向上し、水が埋め込み穴１５２に入り込みにくくなり、防水性，耐湿性が向上する。例えば、トンネル工事などにおいて岩盤から湧出する水や温泉水による錆品質低下，耐用年数の低下等を良好に防ぐことができる。【選択図】図１
