AI Technical Summary
Technical Problem
传统的沿口防水做法是通过钢结构屋面的自然坡度将雨水输送到屋面边缘的排水口，然后由排水口排出，这种依赖自然坡度的排水方式易受屋面平整度影响，檐口部位仅靠边缘排水口，排水效率低且局部积水可能导致渗漏风险
Benefits of technology
1.本实用新型在檐口部位采用防水堵头构造作为第一道防水屏障，与屋面结构接缝处采用螺栓连接、密封材料填塞，下部设置鹰嘴型收边，形成物理性排水导流面，防水堵头与鹰嘴收边形成防排结合“防排结合”的构造，避免雨水倒流渗入室内；主排水采用不锈钢檐沟板与雨水管组合系统，檐沟板按逐跨1%坡度安装，在下包角组件设置滴水孔作为辅助排水措施，提供溢流保障，当主排水系统超负荷时可形成第二排水路径。
