悬臂板结构容易发生质量事故,如1996年7月15日,江西省永新县沙市镇上埠村贺××家的楼房,施工人员在三层阳台上砌筑砖栏板时,宽1000mm、厚80mm 的阳台突然从根部断裂,施工人员掉下,造成一死一伤。原因是阳台配筋为φ6@160,经复核配筋量少47.2%,且主筋在板的中间,承载力只达到设计要求的1/3。1998年2月12日,东里镇庙山村郭××在拆除自家院门雨篷模板时,雨篷倾覆,造成重伤。原因是雨篷横放在只有200 mm 厚的砖墙上,且内外挑出长度不等。1999年9月6日,禾川镇城北农行储蓄所,屋面雨篷悬挑1400mm,根部厚100 The cantilever plate structure is prone to quality accidents. For example, on July 15, 1996, the building of Hexiaojia, Shangyu Village, Shashi Town, Yongxin County, Jiangxi Province, the builders built a brick fence on a three-story balcony and the width was 1000mm. The 80mm thick balcony suddenly broke from the root and the construction staff fell, causing one death and one injury. The reason is that the balcony reinforcement is φ6@160 and the amount of rebar reinforcement is 47.2% less, and the main reinforcement is in the middle of the board, and the bearing capacity only reaches 1/3 of the design requirement. On February 12, 1998, Miaoshan Village, Dongli Township, Guo ××The awning overturned when it demolished the awning template of its own home, causing serious injuries. The reason is that the awning is placed on a brick wall that is only 200 mm thick, and the lengths are picked up from inside and outside. Sep.6, 1999, Aochuan Bank of North Sichuan Agricultural Bank, awning canopy 1400mm, root thickness 100
