有人反应使用的济南卷帘门出现了一些雨水渗漏问题，在下雨时，它的密封性不是特别好，并且会将雨水渗漏在屋内，那么，出现这种情况的原因是什么呢？我们只有了解原因才能进行相应的处理，下面小编就来为您讲解一番。

Someone said that the Jinan roller shutter door used had some rain leakage problems. When it rained, its sealing was not very good, and it would leak rain into the house. So what was the reason for this? We can only deal with it if we understand the reason. The following section will explain it to you.

原因一：铝门窗结构设计或型材选用上存在缺陷

Cause 1: There are defects in the structural design of aluminum doors and windows or the selection of profiles

原因二：对引风面、雨水冲刷面的防渗、防漏考虑不足，过分突出采光及通风需要，“飘窗、落地窗、通窗”等墙体化的门窗大量出现，又不注重建筑构造防水，导致其雨水渗漏问题越来越突出;

The second reason is that insufficient consideration has been given to the seepage prevention and leakage prevention of the air intake surface and the rainwater scouring surface, and excessive emphasis has been placed on the needs of lighting and ventilation. A large number of wall like windows and doors, such as "bay windows, French windows, and through windows", have appeared, and the building structure waterproof has not been paid attention to, leading to the increasingly prominent problem of rainwater leakage;

原因三：设计文件不齐全或未经结构设计，造成锁点不足或铝门窗材料结构强度和挠度达不到要求，导致在正常风压下塑性变形，拉裂或损坏等而产生雨水渗漏;

Cause 3: The design documents are incomplete or without structural design, resulting in insufficient locking points or the structural strength and deflection of aluminum door and window materials fail to meet the requirements, resulting in plastic deformation, crack or damage under normal wind pressure, resulting in rainwater leakage;

原因四：型材选用上简单的套用，导致型材不配套或装配松动或断面挡水高度不足引起的直接漏水;外观上过分注重线条装饰，造成门窗型材接头、转角过多而导致的拼缝封堵缺陷。

Cause 4: The profile selection is simple, resulting in direct water leakage caused by mismatched profiles or loose assembly or insufficient section water retaining height; Too much attention is paid to line decoration in appearance, resulting in too many joints and corners of door and window profiles, resulting in defects of seam sealing.
