管(guan)(guan)道(dao)支吊架(jia)管(guan)(guan)托結構的設(she)計(ji)和形式選用(yong)是管(guan)(guan)道(dao)系統(tong)(tong)設(she)計(ji)中(zhong)的一個(ge)重要組(zu)成部(bu)分,管(guan)(guan)托除(chu)支撐管(guan)(guan)道(dao)重量外,特制的管(guan)(guan)托可平衡管(guan)(guan)系作用(yong)力(li)(li),限(xian)制管(guan)(guan)道(dao)位移和吸收震動,在管(guan)(guan)道(dao)系統(tong)(tong)設(she)計(ji)時,正(zheng)確(que)選擇和布置結構合理(li)的管(guan)(guan)托,能夠(gou)改善管(guan)(guan)道(dao)的應(ying)力(li)(li)分布和對管(guan)(guan)架(jia)的作用(yong)力(li)(li),確(que)保管(guan)(guan)道(dao)系統(tong)(tong)安全運行,并(bing)延長其使用(yong)壽命。

用(yong)以承受管(guan)道荷(he)載(zai)、控(kong)制管(guan)道位移和振動，并(bing)將(jiang)管(guan)道荷(he)載(zai)傳遞(di)到承載(zai)建(jian)筑(zhu)結構上的各種組件(jian)或裝置。一般由管(guan)部、功能件(jian)、連接件(jian)和根部組成。
