农机部第二设计院设计,用于天津某汽车修配厂,现已建成。 中间柱采用Y形柱的特点是厂房柱距可为12米,但屋盖系统仍可采用6米柱距的标准构件,此时边柱仍用6米柱距的矩形柱,以减少围护外墙处理上的麻烦。Y形柱的上部为三角形闭合框架,下部为矩形柱,主筋用Ⅱ级钢筋,混凝土标号为250号。与采用托架方案比较,混凝土用量稍大,钢材用量较省,经济指
Designed by the Second Design Institute of the Ministry of Agricultural Machinery, it is used in a Tianjin auto repair factory and is now completed. The middle column adopts a Y-shaped column, which is characterized by a factory column spacing of 12 meters, but the canopy system can still use standard components with a 6-meter column spacing. At this time, the side column still uses a rectangular column with a 6-meter column spacing to reduce the envelope. Facing the external wall. The upper part of the Y-shaped column is a triangular closed frame, the lower part is a rectangular column, the main ribs are grade II steel bars, and the concrete number is 250. Compared with the bracket scheme, the amount of concrete is slightly larger, the amount of steel is less, and the economy means
