混凝土空心板挤压机的试制成功,为混凝土预制构件生产工艺的改革,实现机械化连续生产,消除笨重体力劳动,提供了新经验,开创了新的途径。本期着重介绍苏州市建筑安装工程公司混凝土预制构件厂、上海市房屋修建公司、武汉市建筑工程科学研究所、沈阳市第三建筑工程公司等单位试制成功的混凝土空心板挤压机,供读者参考。旅大市第二建筑工程公司混凝土构件加工厂制成的混凝土空心板挤压机已在本刊1974年第九期中刊登,这里不再赘述。
The successful trial production of the concrete hollow slab extruder has provided new experience for the reform of the production technology of concrete prefabricated components, the realization of mechanized continuous production, and the elimination of bulky manual labor. In this issue, we will focus on concrete hollow-core slab extrusion presses produced by Suzhou Precast Concrete Prefabrication Factory, Shanghai Housing Construction Company, Wuhan Institute of Construction Engineering, and Shenyang No. 3 Construction Engineering Company. reference. The concrete hollow plate extrusion machine made by the concrete component processing plant of the Second Construction Engineering Company of Luda City has been published in the ninth issue of this volume in 1974 and will not be repeated here.
