由国家建委施工局主持,从八月二十五日至三十日,在大连召开了全国空心板挤压机技术座谈会。出席会议的有六个省市的二十四个单位共四十余名代表。会议期间,江苏、湖北、辽宁等省的有关单位介绍了经验,还谈到了砂轮切割机的试制工作。代表们还观看了旅大市第二建筑工程公司研制成功的空心板挤压机的运转情况。空心板采用挤压成型,是混凝土予制构件成型工艺上的一项重大革新。与会单位一致表示,要以党的基本路线为纲,深入开展批林批孔,促进挤压机的研制工作,使这一革新成果能在较短时间内推广应用,为社会主义建设贡献力量。
Held by the State Construction Commission Construction Bureau, from August 25 to 30, a national hollow board extruder technology conference was held in Dalian. At the meeting, there were more than 40 representatives from 24 units in six provinces and municipalities. During the meeting, relevant units in Jiangsu, Hubei, and Liaoning introduced the experience, and also talked about the trial production of grinding wheel cutting machines. The delegates also watched the operation of the hollow board extruder successfully developed by the Second Construction Engineering Company of Luda City. The use of extruded hollow shells is a major innovation in the molding process of concrete pre-cast components. The participating units agreed that we must take the party’s basic line as the guideline, conduct in-depth approval of approval of forests, and promote the development of extrusion presses so that this innovative result can be applied in a relatively short period of time and contribute to socialist construction.
