    • Plant comprising a rotary drum with a horizontal rotary axis lined, over its outer cylindrical surface with molding means and adapted to pass said molding means during rotation, before various working stations such as concreting, hardening, stripping and core positioning stations. The drum is equipped with beams with a composite profile fixed, notably by welding, longitudinally on the outer periphery of the drum. The beams have a cross-section which has zones adapted to form a roller track parallel to the longitudinal axis of the drum for the rolling and guidance of compacting means for the concrete. It is equipped with fastening means for the molds in a position situated radially outwards with respect to said roller track. It also has sufficient mechanical strength to absorb the major part of the prestressing forces exerted on the cores in the case of manufacturing prestressed concrete elements.
    • 植物包括具有水平旋转轴线的旋转滚筒,其在其外圆柱形表面上以模制装置衬里,并且适于在旋转期间使所述模制装置在各种工作站如混凝土,硬化,剥离和芯定位站之前通过。 滚筒配备有具有固定的复合轮廓的梁,特别是通过焊接在滚筒的外周上纵向地固定。 梁具有横截面,其具有适于形成平行于滚筒的纵向轴线的滚轮轨道的区域,用于滚动和引导混凝土的压实装置。 它配备有用于模具相对于所述滚子轨道径向向外定位的位置的紧固装置。 在制造预应力混凝土构件的情况下,它还具有足够的机械强度来吸收施加在芯上的预应力的主要部分。
