1.综合支吊架的组成。
1. Composition of comprehensive support and hanger.
抗震支座由锚固体、钢筋井架、斜撑和抗震连接构件组成。悬挂杆和管道之间的节点的距离不大于0.1m和螺旋增强根据需要。如果在同一位置设置两个相对刚性的抗震支座,则可以消除悬挂螺钉。考虑地震力的作用,需要增大刚性综合支吊架的悬置螺钉和结构锚固力,锚杆和锚杆的最大承载力应大于地震力。
The aseismic bearing is composed of anchor, steel derrick, brace and aseismic connecting member. The distance between the joints of the suspension rod and the pipeline is not more than 0.1M and the spiral reinforcement is required. If two relatively rigid seismic bearings are installed in the same position, the suspension screw can be eliminated. Considering the effect of seismic force, it is necessary to increase the suspension screw and structural anchorage force of rigid comprehensive support suspension. The maximum bearing capacity of anchor and bolt should be greater than that of seismic force.
2.综合支吊架的施工基础。
2. Construction foundation of comprehensive support and hanger.
地震支护可为给排水系统、空调系统和电气管道系统提供足够的保护。因此,综合支吊架在任何时间、任何安装角度都应大于地震力。水平方向上的地震载荷可以由两个不同方向的地震支撑承担,即侧向地震支撑的侧向载荷和地震支撑的纵向载荷。
Earthquake support can provide adequate protection for water supply and drainage system, air conditioning system and electrical pipeline system. Therefore, the comprehensive support and hanger should be greater than the seismic force at any time and at any installation angle. Horizontal seismic loads can be borne by two different directions of seismic braces, namely lateral seismic braces and longitudinal seismic braces.

4. Construction technology of comprehensive support and hanger for electromechanical installation project.
(1)管道和电缆套管允许纵向偏差,但不得超过最大侧向支撑间距的1/16;管道允许偏差。但不超过管道宽度的两倍。
(1) Longitudinal deviation of pipeline and cable sleeve shall be allowed, but shall not exceed 1/16 of the maximum lateral support spacing; pipeline allowable deviation. But not more than twice the width of the pipe.
(2)水平管为90.在转弯时,必须设置抗震支吊架,其他角度曲线大于1/16的抗震设计间距。侧向和垂直地震支撑吊架是必需的。
(2) Horizontal pipe is 90. When turning, anti-seismic support and suspension must be set. The other angle curves are larger than 1/16 of the seismic design spacing. Lateral and vertical seismic bracing hangers are necessary.
(3)在计算水平地震荷载时,不考虑其他因素就要考虑满载荷载。
(3) When calculating horizontal seismic load, full load should be considered without considering other factors.
(4)考虑到热膨胀系数和收缩系数时,抗震悬架不应限制管道热胀膨胀引起的应力。竖向吊杆应考虑管道的热胀和收缩应力。
(4) Considering the coefficient of thermal expansion and shrinkage, the stress caused by thermal expansion of pipeline should not be limited by the aseismic suspension. The thermal expansion and shrinkage stress of the pipeline should be considered in the vertical suspender.
(5)保温管道的抗震吊架管码应按保温层的尺寸考虑,保温风管应采用门架,水管也应考虑。
(5) The anti-seismic hanger pipe code of the insulation pipeline should be considered according to the size of the insulation layer, the door frame should be used for the insulation duct, and the water pipe should also be considered.
(6)刚性管道的抗震支撑不能安装在建筑物的不同结构部位或功能部位,否则地震作用会引起不同的位移。
(6) The seismic braces of rigid pipes can not be installed in different structural or functional parts of buildings, otherwise the seismic action will cause different displacements.
