    • PROBLEM TO BE SOLVED: To provide a manufacturing method that causes few variation of size and hardness of necessary locations even if an error of a material supply amount is caused in simultaneous molding of many pieces of the concrete spacer block.SOLUTION: A pressure plate 6 that pressurizes an upper surface of a spacer block is divided into a reinforcement steel receiving part 8 of a center part and shoulders part 9 on both sides, and are made to be pressurized by providing the pressure difference between the center part and the shoulder part. Pressurizing of a spacer block shoulder part 2 is enabled corresponding to the variation of the amount at the material supply while the pressure plate shoulder part 9 slides by the pressure lower than the reinforcement receiving part 8.
    • 要解决的问题:提供即使在同时成型多个混凝土隔离块时引起材料供给量的误差,也能够使所需位置的尺寸和硬度几乎不变化的制造方法。解决方案:压板6 将间隔块的上表面加压分为中心部的加强钢接收部8,并且在两侧肩部9,通过在中心部与肩部之间设置压力差而使其加压。 当压板肩部9以低于加强件接收部8的压力滑动时,能够对应于材料供给量的变化而对间隔块肩部2进行加压。
