空腔预制构件生产方法及内模具
摘要：
本公开提供了一种空腔预制构件生产方法及内模具，其中空腔预制构件生产方法，包括：制作空腔预制构件的钢筋笼；在预制构件空腔范围内放置内模具，内模具与空腔适配，并且位于空腔的钢筋笼的至少一部分埋设在内模具中；钢筋笼和内模具一同置于外模具中；在内模具和外模具之间的空隙中充填混凝土形成壳体；混凝土完全定型后，拆除外模具；熔化并去除内模具，得到空腔预制构件。本公开还提供了一种空腔预制构件生产所用的内模具。本公开提升了空腔预制构件品质、提高生产效率、提升构件受力效果。
摘要（英）：

The invention provides a cavity prefabricated member production method and an inner mold. The cavity prefabricated member production method comprises the following steps of manufacturing a reinforcement cage of a cavity prefabricated member; placing the inner mold matched with a cavity of the prefabricated member in the cavity, and at least partially burying a reinforcement cage located in the cavity in the inner mold; placing the reinforcement cage and the inner mold in an outer mold together; filling concrete in a gap between the inner mold and the outer mold to form a shell; removing the outer mold after the concrete is completely formed; and melting and removing the inner mold to obtain the cavity prefabricated member. The inner mold is used for the production of the cavity prefabricated member. By means of the cavity prefabricated member production method and the inner mold, the quality of the cavity prefabricated member is improved, the production efficiency is improved, and thestress effect of the member is improved.
