单层工业厂房的钢筋混凝土屋面,约占整个厂房工程量和投资的三分之一。因此,开展厂房屋面结构的革新具有十分重大的意义。预应力混凝土槽瓦屋面就是单层工业厂房结构改革中的一种屋盖结构。十年来,四川地区采用槽瓦屋面近两百万平米,既为国家节约了大量钢材、木材和水泥,又为加快内地建设速度作出了贡献。 我国是一个多地震的国家。从工业建筑抗震性能来看,轻型屋盖的抗震能力比重型屋盖
The reinforced concrete roof of a single-story industrial plant accounts for about one-third of the entire plant engineering and investment. Therefore, it is of great significance to carry out the renovation of the factory’s building surface structure. The prestressed concrete slot roof is a kind of roof structure in the single floor industrial factory structure reform. In the past ten years, nearly two million square meters of roof tiles have been used in the Sichuan area, which has saved the country a lot of steel, wood and cement, and has contributed to accelerating the speed of construction in the interior. China is a country with many earthquakes. From the point of view of the seismic performance of industrial buildings, the lighter roof has a higher earthquake resistance than the heavy roof
