一、使用效果装配式大板住宅建筑正在蓬勃发展。在生产大板过程中,用靠放架放置大型墙板、楼板和屋面板,既安全又能节省用地。过去用型钢焊成靠架,每个耗钢450公斤,而且容易锈蚀。我们试制了钢筋混凝土靠放架,经过一年多试用证明,完全可以代替钢制靠架。每个钢筋混凝土靠放架用钢量121公斤(包括钢筋、预埋件和收紧器),比钢制靠放架少用30公斤。目前已采用了106个,节省钢材35吨。每个靠放架造价约310元。
First, the use of the effect of large-scale residential building is booming. In the process of producing large plates, large-scale wall plates, floors, and roof panels are placed on the racks, which is safe and saves land. In the past, steels were welded into racks, each of which consumed 450 kilograms of steel and were easily rusted. We have trial-produced a reinforced concrete rack and shelf. After more than one year of trial and trial, we can completely replace the steel rack. The amount of steel for each reinforced concrete rack is 121 kilograms (including steel bars, embedded parts, and tighteners), which is 30 kilograms less than the steel racks. At present, 106 have been used to save 35 tons of steel. Each puts about 310 yuan on the shelf.
