目前,北方地区阳台较普遍地采用钢筋混凝土预制栏板,这种栏板一般以角钢作边框,安装时相互焊接连接。近年来,阳台的长度、宽度不断增大,有时表现为整层的通阳台,这么长的距离,阳台栏板仅靠板间焊接连接,其稳定性及整体刚度显然是不够的。 At present, the balconies in the northern areas are more commonly used reinforced concrete prefabricated fences. Such fences generally use angle steel as the frame and are welded and connected to each other during installation. In recent years, the length and width of the balcony have been increasing, sometimes as a whole through balcony. With such a long distance, the balcony fence board is only connected by welding between boards, and its stability and overall rigidity are obviously not enough.
