旧厂改建扩建设计既要充分利用原有建筑、场地、设备和材料,又要保证改建扩建后的生产使用的更加经济合理。这是我们将一个旧针织品厂改建扩建为中型的消防器材厂设计过程中遇到的主要矛盾。这个旧厂原来的条件很差,要改为多品种的综合性现代化工厂,矛盾就更为突出。我们与工艺设计、建设、施工单位紧密配合协作,深入现场调查研究,认真做好院内外三结合;根据先建生产性建筑,后建生活福利设施的原则,实行分项设计、分项施工,边建成边投产的办法,在比较短的时间内,取得了上马 The expansion and design of the old factory reconstruction should not only make full use of the existing buildings, sites, equipment and materials, but also ensure that the production and use after the reconstruction and expansion are more economical and reasonable. This is the main contradiction encountered in the design process of the expansion of an old knitwear factory into a medium-sized firefighting equipment factory. The original condition of this old factory was very poor, and the contradiction became more prominent when it was changed to a variety of comprehensive modern factories. We cooperated closely with the process design, construction, and construction units to conduct in-depth investigations and researches on the site and to do a good job in the integration of the inside and outside of the hospital. According to the principles of building a productive building first and building a welfare facility afterwards, we implemented sub-item design and sub-item construction. In the relatively short period of time, the method built and put into production was completed.
