当吊筋长度大于1 500 mm时，应设置反支撑，反支撑（镀锌角钢）应与主龙骨连接，角度为45°，反支撑间距一般为2 mm左右。
When the length of hanging steel bar is greater than 1 500 mm, counteracting bearing (i.e. zinc-coated angle steel)should be set up. Countering bearing should be connected to carrying channel. Its angle should be 45°, and its space is commonly about 2 mm.
