| Zusammenfassung: | To provide a ceramic building board capable of suppressing cracks on the inside surface of a pseudo joint.SOLUTION: A ceramic building board 1 has a pseudo joint 2. The pseudo joint 2 has two opposed inner side surfaces 4 (4a, 4b). At least one of the two inner side surfaces 4 (4a, 4b) is constituted of a plurality of inclined surfaces 5 (51a, 52a, 51b, 52b). Among the plurality of inclined surfaces 5 (51a, 52a, 51b, 52b), the inclined surface 5 (52a, 52b) closer to the bottom of the pseudo joint 2 has a gentle gradient with respect to the virtual surface α orthogonal to the thickness direction of the ceramic building board 1.SELECTED DRAWING: Figure 1
【課題】疑似目地の内側面における亀裂を抑制することができる窯業系建築板を提供する。【解決手段】窯業系建築板１は、疑似目地２を有する。疑似目地２は、対向する２つの内側面４（４ａ，４ｂ）を有する。２つの内側面４（４ａ，４ｂ）の少なくとも一方は、複数の傾斜面５（５１ａ，５２ａ，５１ｂ，５２ｂ）で構成される。複数の傾斜面５（５１ａ，５２ａ，５１ｂ，５２ｂ）のうち、疑似目地２の底に近い傾斜面５（５２ａ，５２ｂ）ほど窯業系建築板１の板厚方向と直交する仮想面αに対する勾配が緩やかである。【選択図】図１ |
