抗震支吊架分类及安置准则
Classification and Installation Criteria of Anti-seismic Supports and Suspensions
抗震支吊架可在地震中给予机电各体系充分维护,可用于对抗来自程度及垂直方向的地震力的损坏。依据所维护机电体系的不同,抗震支吊架可分爲管道抗震体系、风管抗震体系和电气(包括电气线管、线槽及桥架)抗震体系。
Seismic support and hanger can be fully maintained in the earthquake, and can be used to resist the damage of seismic force from the degree and vertical direction. According to the different mechanical and electrical systems maintained, the anti-seismic support and suspension can be divided into pipeline anti-seismic system, wind pipe anti-seismic system and electrical (including electrical pipeline, slot and bridge) anti-seismic system.
1.管道抗震加固侧向间隔要求爲:沟槽衔接收道、焊接钢管、钎焊铜管等刚性原料的管线.横向吊架间隔不得逾越12m;HDPE等非刚性原料的管线,横向吊架间隔不得逾越6m。
1. The lateral spacing requirements for seismic reinforcement of pipelines are as follows: pipelines with rigid raw materials such as grooved receivers, welded steel pipes and brazed copper pipes. The spacing of transverse hangers should not exceed 12m; pipelines with non-rigid raw materials such as HDPE should not exceed 6m.
2.管道抗震加固纵向间隔要求爲:沟槽衔接收道、焊接钢管、钎焊铜管等刚性原料的管线,纵向吊架间隔不得超24m;HDPE等非刚性原料的管线,横向吊架间隔不得逾越12m。
2. Longitudinal spacing requirements for seismic reinforcement of pipelines are as follows: pipelines with rigid raw materials such as grooved receivers, welded steel pipes and brazed copper pipes should not exceed 24m in longitudinal suspension spacing; pipelines with non-rigid raw materials such as HDPE should not exceed 12m in transverse suspension spacing.

3.普通刚性风管侧向抗震吊架的间隔爲9m,普通刚性风管纵向抗震吊架的间隔爲18m。
3. The spacing of lateral anti-seismic suspension of common rigid duct is 9m, and that of longitudinal anti-seismic suspension of common rigid duct is 18m.
4.玻璃纤维、塑料和其他非刚性原料风管的侧向抗震吊架,较大间隔爲4.5m.纵向较大间隔爲9m。
4. Lateral anti-seismic suspension of glass fiber, plastic and other non-rigid raw material air ducts, with a larger interval of 4.5 m and a larger longitudinal interval of 9 M.
电气抗震支撑体系的安顿原则
Settlement Principle of Electrical Aseismic Bracing System
5.刚性电气线管、线槽及桥架侧向抗震间隔不得逾越12m,纵向抗震间隔不得逾越24m。
5. The lateral seismic interval of rigid electrical pipes, grooves and bridge frames shall not exceed 12 m, and the longitudinal seismic interval shall not exceed 24 M.
6.非刚性原料电气线管、线槽及桥架横向抗震间隔不得逾越6m,纵向间隔不得逾越12m。
6. The transverse and longitudinal seismic spacing of non-rigid raw material electrical pipes, grooves and bridges shall not exceed 6m and 12m.
抗震支撑体系核算原则:抗震支吊架的安装方式及安顿原则都是依据严峻的力学核算后果判定的,地震力的核算有必要满足规范要求。
Accounting Principle of Seismic Support System: Installation mode and installation principle of aseismic support and hanger are judged on the basis of severe consequences of mechanical calculation. It is necessary to meet the requirements of the code for the calculation of seismic force.
