云南省建筑工程公司在墙体改革实践中,坚持自力更生,土法上马,只用了十多万元投资,建成了三条露天预制生产线,采用普通混凝土制作空心墙板,每年可生产墙板14000多立方米,可建造5万平方米的建筑,目前已建成一批试验房屋和住宅。这种墙板厚度为14厘米,中为8.9厘米的圆孔,采用平模生产,混凝土标号为200,墙板高2.78米,宽3.3米,每块墙板重1.5～2.5吨。楼板、屋面板为空心预应力混凝土构件,厚
In the practice of wall reform, Yunnan Provincial Construction Engineering Company insisted on self-reliance and landscaping. It only used investment of more than 100,000 yuan to build three open-air prefabrication production lines. It used ordinary concrete to make hollow wall panels and produced more than 14,000 wallboards per year. Cubic meters, can build 50,000 square meters of buildings, has already built a group of experimental houses and houses. This type of wallboard has a thickness of 14 centimeters and a circular hole of 8.9 centimeters. It is produced in a flat mold, with a concrete number of 200, a wallboard height of 2.78 meters and a width of 3.3 meters. Each wallboard weight is 1.5 to 2.5 tons. Floor and roof panels are hollow prestressed concrete members, thick
