HEAT-RECEIVING EVALUATION TOOL AND METHOD FOR SPECIFYING THERMALLY DETERIORATED RANGE OF CONCRETE STRUCTURE
PROBLEM TO BE SOLVED: To provide a heat-receiving evaluation tool enabling easy visual evaluation of alteration of concrete by a fire, and a method for specifying the thermally deteriorated range of a concrete structure, using the tool.SOLUTION: The range of deterioration of the concrete structure T caused by heat on the structure T is specified by visual confirmation of the presence or absence of deformation of a heat receiving evaluation tool 1, which is made of material deformed when the material is exposed to temperatures higher than the it can resist and has a base part 11 inserted into a recess 2 in the surface of the concrete structure T and an evaluation part 12 fixed to the base part 11.SELECTED DRAWING: Figure 2
【課題】火災によるコンクリートの変質を目視で簡易に評価することを可能とした受熱評価用具およびこれを利用したコンクリート構造物の熱劣化範囲特定方法を提案する。【解決手段】耐熱温度を超えると変形する材料により形成されていて、コンクリート構造物Ｔの表層部に形成された凹部２に挿入された基部１１と、基部１１に固定された評価部１２とを備えている受熱評価用具１の変形の有無を目視することで、コンクリート構造物Ｔの受熱による劣化の範囲を特定する。【選択図】図２
