我厂自一九八二年以来,在预应力空心板生产中,逐年进行了生产工艺改革,并收到了明显效果。最初我厂系露天台座长线法(钢拉模)生产A、B型空心板。生产中,发现露天台座台面经常变形,空心板产品质量低劣,弊病较多,满足不了用户需要。为此,我厂运用双革自筹资金,逐年分期、分批上了A、B型空心板短线生产 Since 1982, our factory has carried out production process reforms every year in the production of prestressed hollow slabs, and has received significant results. At first, our factory used the long-line method of the outdoor bench (steel pull mold) to produce A and B hollow slabs. During the production, it was found that the table seats of outdoor terraces often deformed, and the quality of the hollow slab products was poor, resulting in more disadvantages, which could not meet the needs of users. To this end, our factory has used double-leaf self-raised funds, and has been on short-term production of A and B hollow slabs in stages and batches on an annual basis.
