但是由于其横向搭接困难，故当建筑屋顶有天窗、风机、气楼等突起构造以及需要与采光带等不同材料组合时，容易产生渗漏。
However because of its difficult lapping, it is easy for a leak to be produced when there are skylights , fans and clearstory etc, at the roof of a building.
增加横向钢筋应均匀分布在锚固区和搭接的间距应不超过5倍的纵向钢筋直径。
The additional transverse reinforcement should be uniformly distributed in the anchorage zone and the spacing of bars should not exceed 5 times the diameter of the longitudinal reinforcement.
附加横向钢筋是没有必要在搭接处。
Additional transverse reinforcement is not necessary in the lapping zone.
