摘要： Method of making an open ended hollow concrete element comprising the steps: arranging a mould about an essentially horizontal roller shaft, the mould comprising a sleeve-shaped mould wall defining the outer peripheral shape of the concrete element and a first and a second end rim each with an inner periphery smaller than the inner periphery of the mould wall at respective end and defining the end surfaces of the concrete element, the mould is rotatably supported by the roller shaft by abutment at the inner peripheries of the first and a second end rims so that the roller shaft upon rotation defines the inner peripheral shape of the concrete elements; rotating the shaft to rotate the mould; feeding curable concrete to the rotating mold; stopping the rotation of the mould; removing the cured concrete element from the mould; w wherein the inner perimeter of the mould wall defines an exterior shape of the concrete element that varies along and/or radially to the direction of the rotational axis. There is further provided an arrangement for making such concrete elements.
摘要翻译：制造开口空心混凝土构件的方法包括以下步骤：围绕基本上水平的辊轴布置模具，所述模具包括限定所述混凝土构件的外周形状的套筒形模壁和每个所述第一和第二端边缘其内边缘在相应端处小于模具壁的内周边并且限定混凝土构件的端面，所述模具通过在第一和第二端边缘的内周缘处抵靠而由辊轴可旋转地支撑，因此滚子轴旋转时限定混凝土构件的内周形状; 旋转轴旋转模具; 将可固化混凝土输送到旋转模具; 停止模具的旋转; 将固化的混凝土元件从模具中取出; w，其中模具壁的内周限定了沿着旋转轴线的方向和/或径向地沿着旋转轴线的方向变化的混凝土元件的外部形状。还提供了制造这种混凝土构件的布置。
