住宅建筑中,因阳台扶手与墙体连接不牢固或因构造措施不恰当.在使用过程中,会造成阳台扶手、栏板与墙体连接处拉裂,甚至会产生过宽的裂缝。有些设计单位、施工单位,在砖混结构的设计与施工中,忽视阳台扶手与墙体之间的连接。而且有些设计图中未明确标注该节点做法,部分施工单位也就不采取任何处理办法,使扶手与墙体之间无连接措施,一旦阳台受荷就会产生裂缝。多数施工单位只在砌墙过程中,按扶手位置预留孔洞,将扶手钢筋插入孔洞内,并在浇筑扶手混
In residential buildings, the connection between the handrail and the wall of the balcony is not firm or due to improper construction measures. During use, the handrail, the wallboard and the wall joint of the balcony may be cracked, and even wide cracks may be generated. Some design units and construction units neglect the connection between the balcony handrail and the wall in the design and construction of the brick-concrete structure. In addition, some design drawings do not clearly label the node, and some construction units do not take any measures so that there is no connection between the handrail and the wall. Once the balcony is loaded, cracks will occur. Most construction companies only set holes in the position of the handrails during the wall-building process, insert the handrail bar into the holes, and mix the handrails.
