随着预应力混凝土的推广应用,其生产方法也越来越多。长线法生产预应力空心板就是近几年来在单根生产的基础上发展起来的一种方法。我公司第二工程处的广大职工,在学习兄弟单位经验的基础上,自己动手制成张拉小车,在60米长的混凝土底模上,实现了张拉抽芯脱模机械化,并做到了抽芯滑模一次完成。这不仅大大减轻了劳动强度,提高了工效,节约了木材,还提高了构件质量。现将其模具、张拉卷扬小车及其有关问题介绍如下:
With the popularization and application of prestressed concrete, its production methods are more and more. Long-line production of prestressed hollow slabs is a method that has been developed on the basis of single production in recent years. The staff of the company’s second engineering department, based on the experience of the fraternal units, made the trolley by themselves, and on the concrete bottom mold of 60 meters in length, realized the pulling and pulling of the core and released the mechanization. Pulling the core slide mold once. This not only greatly reduces labor intensity, improves work efficiency, saves wood, but also improves the quality of components. The following are the descriptions of its molds, pulling and lifting cars and related issues:
