我厂生产的预制混凝土踏步板,1986年以前,是依靠木制翻模工艺进行生产的。这种生产工艺落后,生产出的构件质量稳定性差,台座占用率大,养护费用高,木模板消耗量大,工人劳动强度大,生产效益低。直接影响与工程的进度配合。为扭转这种状况,借鉴我单位预制混凝土过梁拉模生产工艺原理,我们试制出了由卷扬机牵引的预制混凝土踏步板钢拉模。
The prefabricated concrete tread board produced by our factory was produced before 1986 by relying on the wood turning mold. This production process is backward, the quality of the components produced is poor, the occupancy rate of the pedestal is large, the maintenance cost is high, the consumption of the wood formwork is large, the labor intensity of the workers is large, and the production efficiency is low. Directly influences the progress of the project. In order to reverse this situation, we learned from the principle of the production technology of prefabricated concrete lining die of our company. We produced a precast concrete stepping plate steel drawing die that was hauled by a winch.
