支吊架组件荷载性能试验适用于以地震力为主要荷载,建筑抗震设防烈度为6度~9度的建筑机电设备抗震支撑设施试验检验。分别将4套支吊架组件安装到HRJ疲劳试验机,斜撑与主吊螺杆成45°夹角,组件试样在水平面内的位移量不超过50mm。其他30°60°夹角的试验值,可通过换算方式得到。组件经过15次相同力值振幅的循环加载后,继续受到力值振幅递增的循环荷载,达到规定的终止条件时,确定组件的试验荷载。组件试验循环荷载频率为0.1Hz。
CJ/T476-2015建筑机电设备主要包括建筑给水、供暖通风与空调、电气、燃气、消防等为建筑使用功能服务的附属机械、电气构件、部件和系统。抗震吊支架由锚固体、加固吊杆、抗震连接构件及抗震斜撑组成,与建筑结构体牢固连接、以地震力为主要荷载的抗震支撑系统。抗震支吊架是对机电设备及管线进行有效保护的重要抗震措施。
