EXPLOSIVE FRACTURE PREVENTION STRUCTURE
To provide an explosive fracture prevention structure which can be simply and inexpensively configured, and can efficiently dissipate coagulated water and water vapor that is generated inside concrete due to residual moisture in the concrete or high temperature in firing.SOLUTION: An explosive fracture prevention structure has paths 3 for dissipating coagulated water and water vapor generated inside concrete due to residual moisture in a concrete column 1 or high temperature in firing to the outside. The path 3 is formed by mutually communicating a parallel direction path 31 in a direction parallel to a heating surface of the concrete column 1 and an orthogonal direction path 32 in a direction orthogonal to the heating surface in a direction crossing the parallel direction path 31.SELECTED DRAWING: Figure 1
【課題】簡易かつ安価に構成することが可能で、なおかつ、コンクリート内の残留水分または火災時等の高温によってコンクリート内部に生じる凝集水と水蒸気を効率的に外部に逸散させることができる爆裂防止構造を提案する。【解決手段】コンクリート柱１内の残留水分または火災時等の高温によってコンクリート内部に生じる凝集水と水蒸気を外部に逸散する経路３を有する爆裂防止構造である。経路３は、コンクリート柱１の加熱面に対して平行方向の平行方向経路３１と、平行方向経路３１と交差する方向に沿った加熱面に対して直交方向の直交方向経路３２とが互いに連通してなる。【選択図】図１
