1.侧/纵向斜撑装置的垂直角度为45°,可依据现场实践状况恰当调整。
1. The optimum vertical angle of side/longitudinal bracing device is 45 degrees, which can be adjusted appropriately according to field practice.
2.管线穿越建筑沉降缝时,应思索沉降位移的设计。
2. The design of settlement displacement should be considered when the pipeline crosses the building settlement joint.
3.计算程度地震力荷载时,只需思索满负荷重量而不需求思索其他要素。
3. When calculating seismic loads of degree, we need only consider the full load weight without considering other factors.
4.程度管道在90°转弯时,需设抗震支吊架;其他角度转弯长度大于抗震设计间距的1/16时,需设侧向及纵向抗震支吊架。
4. When the degree of pipeline turns at 90 degrees, it is necessary to install anti-seismic brackets; when the length of other angle turns is greater than 1/16 of the seismic design spacing, it is necessary to install lateral and longitudinal anti-seismic brackets.
5.保温管线的抗震吊架管码需按保温后的尺寸思索,门形吊架用于保温风管,水管亦按此思索。
5. Seismic hanger code of insulation pipeline should be considered according to the dimension after insulation. Portal hanger is used for insulation air pipe, and water pipe should also be considered accordingly.
6.管道和电线套管允许纵向偏移,但不得超越大侧向支撑间距的1/16;风管允许偏移,但不得超越风管宽度的2倍。
6. Pipeline and wire sleeve are allowed to deviate longitudinally, but not more than 1/16 of the maximum lateral support spacing; duct is allowed to deviate, but not more than twice the duct width.

7.单管抗震支撑双向侧向或纵向或具有侧/纵向作用的拐点抗震支撑,应直接与管线或电线套管衔接。应留意支管或小一级管线的支撑不能作为主管的抗震支撑,即不能作为另一方向的支撑。
7. The single-pipe seismic brace should be connected directly with the pipeline or the cable sleeve for bidirectional lateral or longitudinal or inflection point seismic brace with lateral/longitudinal action. It should be noted that the bracing of branch or small primary pipeline can not be used as the seismic bracing of the main pipe, that is, it can not be used as the bracing of the other direction.
8.抗震吊架不应限制管线热胀冷缩产生的应力,当把热胀冷缩要素思索在内时,纵向吊架应在构件选型上思索所选型号应能抵御管线的热胀冷缩应力。
8. Seismic hangers should not limit the stress caused by thermal expansion and contraction of pipelines. When considering the factors of thermal expansion and contraction, longitudinal hangers should consider the type of components selected to resist the thermal expansion and contraction stress of pipelines.
9.用于刚性的管道抗震支撑不能装置于建筑的不同构造部位或功用部位,否则会因地震作用而产生不同的位移。
9. Seismic braces for rigid pipelines can not be installed in different structural or functional parts of buildings, otherwise different displacements will be produced due to seismic action.
10.对水、电、风系统的单管或多管共用门型吊架,无论侧向或纵向斜撑,斜撑偏离中心线2.5°时不会影响其承载力。
10. The bearing capacity of single-pipe or multi-pipe common portal hangers for water, electricity and wind systems will not be affected when the braces deviate from the central line 2.5 degrees, regardless of the lateral or longitudinal braces.
