在唐山地区的中小型工业厂房中,我们采用墙头跑吊车的作法,为解决吊车梁的问题提供了一种因陋就简的途径。这里所介绍的是唐山地区丰润县农机厂的金工车间,跨度15米,3吨梁式吊车,轨顶标高5.5米(图1)。其作法是将外围护结构与吊车梁合一,在墙头上加钢筋混凝土垫,上铺轨道代替吊车梁(图2),从而省去了钢筋混凝土柱和吊车梁。车间投产以后 In the small and medium-sized industrial plants in the Tangshan area, we adopted the practice of running cranes at the wall to provide a solution to the problem of crane girders. Here is the metalworking workshop of Fengrun Agricultural Machinery Factory in Tangshan District, spanning 15 meters, 3 tons of beam cranes, and the rail top elevation of 5.5 meters (Figure 1). Its practice is to unite the external protection structure with the crane beam, add reinforced concrete mats on the wall top, and replace the crane beam with the upper track (Figure 2), thus eliminating the need for reinforced concrete columns and crane beams. After the workshop is put into production
