预应力钢筋混凝土马鞍形屋面板的研制和推广工作,是在两条路线的激烈斗争中产生和发展的。在有关领导的关怀支持下,我们坚持自力更生,土法上马的革命精神,进行了6米、12米、24米跨的马鞍形屋面板试制试压,并建成宿舍、仓库、食堂(如图1)、无吊车厂房等试点工程约3000平米, The development and promotion of pre-stressed reinforced concrete saddle-shaped roof panels was created and developed in the fierce struggle between the two routes. With the support of concerned leaders, we insisted on self-reliance and the revolutionary spirit of indigenous methods. We carried out trial production of saddle-shaped roof panels with 6-meter, 12-meter, and 24-meter-span spans, and completed dormitory, warehouse, and canteen (see Figure 1). ) The pilot project with no crane plant is about 3,000 square meters.
