有人反應使用的濟南卷簾門出現了一些雨水滲漏問題，在下雨時，它的密封性不是特別好，并且會將雨水滲漏在屋內，那么，出現這種情況的原因是什么呢？我們只有了解原因才能進行相應的處理，下面小編就來為您講解一番。

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：鋁門窗結構設計或型材選用上存在缺陷

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

原因二：對引風面、雨水沖刷面的防滲、防漏考慮不足，過分突出采光及通風需要，“飄窗、落地窗、通窗”等墻體化的門窗大量出現，又不注重建筑構造防水，導致其雨水滲漏問題越來越突出;

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：設計文件不齊全或未經結構設計，造成鎖點不足或鋁門窗材料結構強度和撓度達不到要求，導致在正常風壓下塑性變形，拉裂或損壞等而產生雨水滲漏;

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：型材選用上簡單的套用，導致型材不配套或裝配松動或斷面擋水高度不足引起的直接漏水;外觀上過分注重線條裝飾，造成門窗型材接頭、轉角過多而導致的拼縫封堵缺陷。

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.
