(一) 在毛主席无产阶级革命路线的指引下,我局从一九五九年开始了以大型承重壁板为主的墙体技术改革工作。在国家建委、北京市建委的关怀和支持下,以及中央和市属大专院校、科研单位的大力协助下,采用振动砖壁板结构先后试建了四至五层居住建筑93拣,27.6万平方米,工程造价与同类砖砌建筑相比,由原来高百分之三十三降低到仅高百分之四。从一九六四年开始,研究利用粉煤灰矿渣等工业废料制作硅酸盐混凝土大型壁板,到一九七四年,共试建了同类居住建筑82栋,16万平方米。特别是在无产阶级文化大革命的推动下,通过
(1) Under the guidance of Chairman Mao’s proletarian revolutionary line, the Bureau began the reform of the wall technology with large-scale load-bearing siding in 1959. With the help of the State Construction Commission and the Beijing Municipal Construction Committee and the assistance of the central and municipal colleges and universities and research institutes, a four-to-five-story residential building with a vibrated brick wall structure has been built with 93 picks and 276,000 square meters. In meters, the project cost was reduced from the original 33% to just 4%, compared with similar brick buildings. Since 1964, research has been conducted on the production of large-scale silicate concrete slabs from industrial waste such as fly ash slag. By 1974, a total of 82 residential buildings of the same type had been built, totaling 160,000 square meters. Especially through the promotion of the proletarian cultural revolution,
