1、管道支吊架设计技术规定参考管道支吊架设计技术规定SH/P26-2005上海化工设计院有限公司二OO五年三月管道支吊架设计技术规定1、支吊架分类按支架的作用分为三大类：承重架、限制支架和减振架。1.1 承重架：用来承重受管道的重力及其它垂直向下载荷的支吊架。1.1.1 滑动架：在支承点的下方支撑的托架，除垂直方向支撑力及水平方向摩擦力外，没有其他任何阻力。1.1.2 杆式吊架：在支承点的上方以悬吊的方式承受管道的重力及其他垂直向下的载荷，吊杆处于受接状态。1.1.3 弹簧支吊架：用于一定范围内有垂直方向位移的管道、设备支、吊，载荷变化率25%。1.1.4 恒力弹簧支吊架：用于有较大垂直方向位移的

2、管道支吊。使用载荷偏差6%。1.1.5 滚动支架：采用滚动支承，减小管道因轴向位移而产生对支架的推力。1.1.6 带聚四氟乙烯支架：在支架摩擦面粘贴聚四氟乙烯板，减小管道应轴向位移而产生对支架的推力。1.2 限制性支架：用来阻止、限制或控制管道系统热位移的支架。1.2.1 导向架：使管道只能沿轴向移动的支架。并能限制侧向位移的作用。1.2.2 限位架：限位架的作用是限制轴向、侧向位移。在某一个方向上限制管道的位移所要求的数值，称为定值限位架1.2.3 固定架：不允许支承点有三个方向的线位移和角位移。1.3 减振支架：用来控制或减小除重力和热膨胀作用以外的任何力（如物料冲击、机械振动、风力及地震

3、等外部载荷）的作用所产生的管道振动的支架。2、支吊架结构的组成部份从管道支承的结构及连接关系等方面考虑，由管部附件、连接配件、特殊功能件、辅助钢结构及生根件等组成。2.1 管道附件：是附着管道上的支架部件，是支架与管道外壁相连接或接触的部件。如管托、管卡、U形螺栓、吊耳、支耳、支腿等。2.2 连接配件：指连接的另部件、吊杆等。2.3 特殊功能件：指弹簧支吊架、限位杆等部件，起到特殊功能作用。2.4 辅助钢结构：一般由型钢及钢板制造。作用是将管道支承点的力传递给土建结构或设备外壁。2.5 支架生根件附在设备或土建钢筋混凝土结构上，从备料角度来讲，不算管道支架的组成部分，但从管道支架的设计方向看，

4、可作为支架一个重要组成部分。3、标准支架及通用支架3.1 标准支架指整个结构各部位的尺寸是已定不变的。例如：管托类属于标准架，所指定型号、管径等一般包括在系列号中。结构型式见HG/T21629-1999 A类管架标准另部件。3.2 通用支架指管道支吊架的型式已定，但部份尺寸需在选用时确定。结构型式见HG/T21629-1999 B至M类。因此，通用支架采用以表格为主的有图又有表的形式，并在表中填入所确定的尺寸。图纸一般为A3图幅。具体内容详见“表3.2管架数据一览表”。3.3 非标支架指辅助钢结构的高度一般不超过4米，较高的钢结支架应提交土建专业设计。4、支吊架间距4.1 装置内不保温管道基本

5、跨距表4.1。4.2 装置内保温管道基本跨距表4.2。4.3 装置外不保温管道基本跨距表4.3。4.4 装置外保温管道基本跨距表4.4。4.5 垂直管道支架间距：大致可按照不保温管充水的水平管道支架间距进行圆整。4.6 水平弯管管道允许支架间距的确定。水平90弯管两个支架间距的管道展开长度L，不应大于水平直管段上两个支架间距的0.7倍。图4.7。图4.7 水平90弯管 图4.8 尽端直管4.8 尽端直管段管道允许支架间距的确定尽端直管两个支架间距的管道长度L不应大于水平直管段上两个支架间距的0.8倍，如图4.8。4.9 装有波纹膨胀节管道的支架间距膨胀节两端支架设置参照图4.9所示并结合产品厂
