1、根据设计图纸中各种管径的排列形式，确定各支架的宽度，设计中没有对支架材料规格明确规定，根据规范及监理的意见，全部采用L40×4的角钢制作。 2、角钢L40×4必须是合格品，并具有该批材料的质量证明书。 *作要点 1、工艺流程：确定尺寸、标高→下料→钻孔→焊接→防腐→放线→安装 2、下料时采用切割焊机下料，钻床钻孔；严禁使用气焊进行下料和开孔。固定支架的孔径为φ10.5; 木砖固定的孔径为φ6.5。 3、刷油防腐时，必须清除角铁上的铁锈及油污，露出金属光泽且后方可进行刷油防腐。希望我的回答可以帮助到你。

1，固定支架是暖通空调中经常用到的一种支架，它在系统中起固定和支撑管道的作用，一般由设计人员根据需要设定具体位置，各种规范中规定较少，补偿器用于吸收管道因温度增高引起膨胀造成的长度增大。有“г”型、“Z”型的自然补偿器和方形、套筒、波纹管补偿器等多种形式，设计人设计时依据伸缩量、管径等条件选用。可是现在许多设计人员对此不重视，或漏画，或胡乱对付，位置和数量都没有经过仔细推敲，不甚合理，本文根据笔者经验，总结了一套在室内95/70℃热水采暖系统设计中快速设置固定支架和补偿器的方法，结合示例详述如下，望能起到抛砖引玉的作用。由于成文比较仓促，文中定有许多不足之处，望各位指正。　　2，设计计算　　系统中固定支架的设置应在管径计算完毕之后，此时系统管道的布置已经完成，系统每一段的管径已经计算确定，固定支架可以开始布置。　　2.1计算管道热伸长量　　△X——管道的热伸长量,mm;　　t1——热媒温度,℃,　　t2——管道安装时的温度,℃,一般按-5℃计算.　　L——计算管道长度m;　　0.012——钢铁的线膨胀系数,mm/m·℃按t1

95℃简化得　　空调器应安装在儿童不易触及的地方，尽量避开自然条件恶劣(如油烟重、风沙大，阳光直射或有高温热源)的地方。　　室外机组安装架承载能力至少不低于180公斤。建筑物内部的过道、楼梯、出口等公用地方不应安装空调器的室外机。空调器的室外机组不应占用公共人行道，沿道路两侧建筑物安装的空调器其安装架底部距地面的距离应大于2.5米。空调器的室外机应尽可能远离相邻方的门窗和绿色植物，与对方门窗距离不得小于3米，“不锈钢空调支架寿命应长于空调寿命”，虽然一般家电的使用寿命为8～10年，但如果空调使用少未损坏或保养较好，居民非主观性地延长了空调的使用寿命，而事实上，这样的情况非常普遍。此外，用户应“定期向有关部门报检”。

中央空调管道支架安装方法1、如果所选的现场用管尺寸不同于分歧管接头尺寸，则用切管器在所需的接管尺寸的中部切开，并去除毛刺。 2、安装分歧管尽量使其分歧管竖向或水平。水平放置时，倾斜度在±15º以内。放置在正确的位置后，充氮焊接。 3、注意事项：　　a、对多分歧管路系统，每根管子都贴上标签，使分歧后的连接管与室内机对应，防止接错。　　b、分歧管的进口侧，至少要有300mm的直管段。 4、*洗：*洗是用氮气压力去除管内的外来物（灰尘，水份，焊接造成的氧化铍等）。中央空调*洗步骤：　　a、将压力表装在氮气瓶上；　　b、用盲塞将室内机A侧之外的所有铜管接口处堵塞好。　　c、打开氮气瓶阀，维持压力在5 Kg/cm2。检查氮气是否流过室内机A液管　　a、用手中的绝缘材料抵住管口，当压力大的无法抵住时，快速释放绝缘物。再用绝缘物抵住管口，如此反复几次，直到没有没有杂物*出为止。　　b、关闭氮气主阀对室内机B重复以上*作　　对液管*洗完毕后，再对气管进行*洗，*洗步骤跟*洗液管步骤一样。　　中央空调分歧管起着制冷剂分流的作用，所以分歧管的选择和安装对于多联机组的运行是非常重要的。
