    • A device (1a) for protecting lifting inserts having a tubular body (14) during embedding in a concrete component (5), comprising an elastically deformable element (2) insertable in the axial end (3) of the tubular body (4) of the lifting insert directed toward the outside of the prefabricated component (5) engageable for lifting the prefabricated component (5). The elastically deformable element (2) occupies an axial portion of the tubular body (4) starting from axial end (3). The device (1a) comprises expansion elements (11,12), which act on the elastically deformable element (2) to cause a radial expansion thereof through the elastically deformable element (2) engaging whereby the inside walls of the tubular body (4) to prevent infiltration of concrete through the axial end (3) of the tubular body (4) of the lifting insert.
    • 一种用于在混凝土构件的嵌入期间保护具有管状主体(14)升降的插入装置(1A)(5),包括弹性变形的元件(2)在所述管状体的轴向(3)可插入端(4)的 提升刀片朝向预制构件(5)接合的外部用于提升预制组分(5)。 可弹性变形的元件(2)占据在轴向在所述管状体的部分(4)从轴向端部(3)开始。 该设备(1A)包括膨胀元件(11,12),可弹性变形的元件上,其作用(2)通过(2)接合的弹性变形的元件导致它们的径向扩张,由此所述管状主体的内壁(4) 以防止混凝土的浸润通过提升插入件的管状主体(4)的轴向端部(3)。
