摘要： Method and apparatus for casting prefabricated concrete products with a substantially horizontal slipform casting process, where the concrete mass is fed in at least one feeding stage to a slipform casting mold compacting and defining the product to be cast, wherein at least one part is embedded in the concrete mass after the at least one concrete mass feeding stage and before the final compaction of the upper surface of the product to be cast.

摘要： A method and apparatus are for fabricating a concrete product in a slip-form casting process, in which method concrete mix is fed into a slip-form mold of a defined cross section moving progressively in the casting process so as to obtain a concrete product of a desired shape. The method includes an interruptible guidance control of the prestressing tendons so as to allow the tendon guides to travel past supplementary parts such as reinforcing steels connected to the prestressing tendons.

摘要： In a method of casting in a horizontal mould a hollow, reinforced tapering concrete post having a thin wall and particularly a length exceeding 10 to 15 m, there is placed in the mould a tapering reinforcing cage or basket in which a core, e.g. a steel core, is inserted to form a substantially annular mould chamber. Said mould chamber is closed with the exception of an upper filling slot. A readily pourable concrete mass is charged to the mould from above through said filling slot. The mould is then vibrated without being rotated such that concrete fills the annular mould chamber. Hardening of the concrete is accelerated by heating, and the core is withdrawn from the formed post before the concrete has completely hardened. The finished post is then removed from the mould. The concrete mixture used shall have a settling or slump measurement of between 1 and 5 cm prior to charging a flow-promoting agent, and a settling or slump measurement of between 12 and 14 cm subsequent to charging said flow-promoting agent. The concrete mixture has a stone size of at the most 8 mm. The core is preferably withdrawn 1.5 to 4 hours after completion of the casting operation.The invention also concerns a mould for casting concrete posts of the above mentioned kind.
摘要翻译： 在水平模具中铸造具有薄壁并且特别是超过10至15μm的长度的中空加强的锥形混凝土柱的方法中，在模具中放置有锥形的加强笼或篮，其中， 插入钢芯以形成大致环形的模腔。 除了上部填充槽之外，所述模具室是关闭的。 通过所述填充槽将容易倾倒的混凝土块从上方装入模具。 然后，模具不会旋转而振动，使得混凝土填充环形模具室。 混凝土的硬化通过加热加速，并且在混凝土完全硬化之前将芯从成型的柱中取出。 然后将完成的柱从模具中取出。 使用的混凝土混合物在充入流动促进剂之前应具有1至5cm之间的沉降或坍落度测量，以及在充入所述流动促进剂之后的12至14cm之间的沉降或坍落度测量。 混凝土混合物的石头尺寸最大为8毫米。 核心优选在铸造操作完成后1.5至4小时内取出。 本发明还涉及一种用于铸造上述类型的混凝土柱的模具。

摘要： A roll of reinforcing wire mesh is mounted behind the last concrete hopper on the frame of a movable concrete plank-laying machine. The wire mesh is guided forwardly between an upper portion of the hopper and the lower end of a concrete-delivering chute so that the concrete passes through the wire mesh and into the hopper. A guiding plate connected to an upright wall of the hopper guides the wire mesh downwardly beneath the hopper where its direction is reversed so that it is laid on the concrete plank while concrete is discharged thereover from the hopper.

摘要： The present invention relates to a method for the manufacture of concrete objects by means of a slidable moulding assembly by feeding a concrete mass down from a movable container onto a support bed and vibrating the concrete for the compression of the concrete. The invention eliminates any risk of fissures in the final object primarily by inserting a reenforcement rod into the mass along with some water through an axial bore in a sleeve guide on the container, after a majority of the compressing or compacting of the mass has occurred. A container-carried rotating screw is used for separating, by means of its threads, the concrete remaining in the container from the concrete in the object being formed.
