EXTRUSION MOLDED CEMENT PLATE
PROBLEM TO BE SOLVED: To eliminate a pull crack and other defects during manufacture of an extrusion molded cement plate and enhance the fire resistance efficiency.SOLUTION: An extrusion molded cement plate 10 is configured as follows: a plurality of void parts 2 is disposed in parallel to each other with a vertical rib part 4 in between that connects two side wall parts 3 of a plate body 1 in the thickness direction of the plate body 1; the vertical rib part 4 has at least a tier of a pair of protruded parts 5 in the thickness direction of the plate body 1; an overall thickness A of the plate body 1 is 80 mm or more and up to 110 mm; a thickness B of the side wall parts 3 is 15 mm or more and up to 25 mm; a thickness C of the vertical rib part 4 is (B-5)mm or more and up to (B+5)mm; a width D of the hollow part 2 along the width direction of the plate body 1 is 35 mm or more and up to 70 mm; a width E of the protruded part 5 along the thickness direction of the plate body 1 is 5 mm or more and up to 15 mm; and a ratio F/D between the width D of the hollow part 2 and the extrusion height F of the extruded part 5 is 0.40 or more and up to 0.45 when the thickness B is 15 mm or more and less than 20 mm, and 0.20 or more and up to 0.45 when the thickness B is 20 mm or more and up to 25 mm.
【課題】引き割れ等の製造時の不具合を解消し、耐火性能の向上を図る。【解決手段】押出成形セメント板１０は、中空部２が、板体１の両側壁部３との間を板体１の厚み方向に連結する縦リブ部４を介して複数平行に設けられ、縦リブ部４には、一対の凸条部５が板体１の厚み方向に少なくとも一段設けられ、板体１全体の厚みＡが８０ｍｍ以上１１０ｍｍ以下とされ、両側壁部３の厚みＢが１５ｍｍ以上２５ｍｍ以下とされ、縦リブ部４の厚みＣが（Ｂ−５）ｍｍ以上（Ｂ＋５）ｍｍ以下とされ、中空部２の板体１の幅方向に沿う幅Ｄが３５ｍｍ以上７０ｍｍ以下とされ、板体１の厚み方向に沿う凸条部５の幅Ｅが５ｍｍ以上１５ｍｍ以下とされ、中空部２の幅Ｄと凸条部５の突出高さＦとの比率Ｆ／Ｄは、前記厚みＢが１５ｍｍ以上２０ｍｍ未満では０．４０以上０．４５以下、前記厚みＢが２０ｍｍ以上２５ｍｍ以下では０．２０以上０．４５以下を満足する構成とされる。【選択図】 図２
