Precast Concrete Element GeneralProduction and manufacturing related properties common to different types of precast concrete elements. The Pset can be used by a number of subtypes of IfcBuiltElement. If the precast concrete element is a sandwich wall panel each structural layer or shell represented by an IfcBuildingElementPart may be attached to a separate Pset of this type, if needed. Some of the properties apply only for specific types of precast concrete elements.
生産(設計)と製造(メーカー)でタイプの異なるプレキャストコンクリート要素(部材)に、共通の属性(プロパティ)を関連付けた。Psetは多くのIfcBuildingElementのサブタイプとして使用できる。もしプレキャストコンクリート要素が壁板であるとしたら、IfcBuildingElementPartで表される各々の構造的な層かシェルは、このタイプの別々のPsetで結び付くかもしれない。幾つかの属性が、特定なタイプのプレキャストコンクリート要素のためだけに適用される。

HollowCorePlugging P_SINGLEVALUE / IfcLabel
Hollow Core PluggingA descriptive label for how the hollow core ends are treated: they may be left open, closed with a plug, or sealed with cast concrete. Values would be, for example: 'Unplugged', 'Plugged', 'SealedWithConcrete'. This property applies to hollow core slabs only.
くぼみの充填(定着部の?)くぼみをどのように扱うのかについて書かれたラベル:開けたままにするか、プラグで塞ぐ、または後詰めコンクリートで塞ぐ。例えば、「塞がない」、「塞ぐ」、「コンクリートで塞ぐ」と書かれるだろう。この属性はスラブに開けられたくぼみにも適用される。
CamberAtMidspan P_SINGLEVALUE / IfcRatioMeasure
Camber At MidspanThe camber deflection, measured from the midpoint of a cambered face of a piece to the midpoint of the chord joining the ends of the same face, as shown in the figure below, divided by the original (nominal) straight length of the face of the piece.
BatterAtStart P_SINGLEVALUE / IfcPlaneAngleMeasure
Batter At StartThe angle, in radians, by which the formwork at the starting face of a piece is to be rotated from the vertical in order to compensate for the rotation of the face that will occur once the piece is stripped from its form, inducing camber due to eccentric prestressing.
BatterAtEnd P_SINGLEVALUE / IfcPlaneAngleMeasure
Batter At EndThe angle, in radians, by which the formwork at the ending face of a piece is to be rotated from the vertical in order to compensate for the rotation of the face that will occur once the piece is stripped from its form, inducing camber due to eccentric prestressing.
Twisting P_SINGLEVALUE / IfcPlaneAngleMeasure
TwistingThe angle, in radians, through which the end face of a precast piece is rotated with respect to its starting face, along its longitudinal axis, as a result of non-aligned supports. This measure is also termed the ‘warping’ angle.
Shortening P_SINGLEVALUE / IfcRatioMeasure
ShorteningThe ratio of the distance by which a precast piece is shortened after release from its form (due to compression induced by prestressing) to its original (nominal) length.
PieceMark P_SINGLEVALUE / IfcLabel
Piece MarkDefines a unique piece for production purposes. All pieces with the same piece mark value are identical and interchangeable. The piece mark may be composed of sub-parts that have specific locally defined meaning (e.g. B-1A may denote a beam, of generic type ‘1’ and specific shape ‘A’).
DesignLocationNumber P_SINGLEVALUE / IfcLabel
Design Location NumberDefines a unique location within a structure, the ‘slot’ for which the piece was designed.
