我厂与江苏省建筑科研所合作,在75年5月试制成功一台八孔空心板挤压成型机。为了挤压机生产工艺配套,配置一台18米跨度(轨距)龙门吊车,做了2000米~2专用场地(20×100米),在跨度中间做了十三条专用台座,组成一条露天长线挤压成型工艺生产线。经过三年多的生产实践证明,这条生产线效果较为显著。随后扩建的第二条生产线,又于78年7月完成投产。我厂从75年5月开始边试验、边生产,至78年8月止共生产了八孔空心板(高110×宽800×长3400毫米)25000余块,计4000多米~3,产品经过静荷载结构
Our factory cooperated with the Jiangsu Provincial Institute of Construction and Scientific Research. In May of the year 75, we successfully produced an eight-hole hollow plate extrusion machine. In order to support the production process of the extrusion machine, a 18-meter-span (gauge) gantry crane was deployed and a special space of 2000m~2 (20x100m) was made. In the middle of the span, there were 13 dedicated pedestals to form an open air. Long-term extrusion molding production line. After more than three years of production practice, this line has achieved significant results. The subsequent expansion of the second production line was completed in July 78. Our factory has been conducting trials and productions since May of the year 75. By August of the year of August 78, we have produced more than 25,000 hollow plate (110 x 800 x 3400 mm long) with more than 4000 meters~3. Static load structure
