我厂原用砖胎模生产预应力混凝土大型屋面板,现改用活动钢胎模。具体做法是:在110米长台座上布置活动钢胎模30个,计两条生产线,每条生产线可生产15块大型屋面板,每月平均生产75块,全年可生产1000块,使用实践证明,具有良好的经济效益。一、活动钢胎模的制作钢模按照《图集》的节点大样图为标准,结合原固定砖混凝土胎模工艺的生产经验,作了一些局部改进。即对板的内面、两端和两侧的曲率半径分别由原来的 R=60毫
Our factory originally used pre-stressed concrete large-scale roof slabs with brick molds, and now we use the movable steel tire molds. The specific approach is: arrange 30 active steel tire molds on the 110-meter-long pedestal, and count two production lines. Each production line can produce 15 large-scale roof plates, with an average monthly production of 75 pieces, and 1000 pieces can be produced throughout the year. Prove that it has good economic benefits. First, the production of movable steel tire mold Steel mold in accordance with the “atlas” of the node diagram as a standard, combined with the production experience of the original fixed concrete tire mold process, made some local improvements. That is, the radius of curvature of the inner surface, both ends, and both sides of the plate is respectively from the original R=60 millimeters.
