悬挑构件存在倾覆问题。避免其倾覆破坏的措施有二:(1)设计结构合理,要求在结构设计上选择与悬挑构件相平衡的构造做法,且应满足抗倾覆条件;(2)施工措施得当,要求施工管理人员懂得所施工的悬挑构件抗倾覆的构造形式,按正确的施工程序施工。下面分别介绍阳台、雨篷、挑檐等悬挑构件抗倾覆的构造形式,以及在施工中应注意的问题。 Cantilevered components have overturning problems. There are two measures to avoid overturning damage: (1) The design structure is reasonable, and it is required to select structural methods that are balanced with the cantilevered components in the structural design, and the anti-overturning conditions should be met; (2) Appropriate construction measures require construction management personnel Understand the construction structure of the cantilevered members against overturning, and follow the correct construction procedures. The following sections describe the anti-overturning structures of cantilevered components such as balconies, awnings, and provocations, and the issues that should be addressed during construction.
