雨棚安装质量好不好，外行看“平不平”，内行看“排水、固定、密封”三道关。等下雨才发现漏水，返工成本比安装费还高。学会这套“三看”验收法，装完当场就能验出问题。

Whether the installation quality of the canopy is good or not depends on whether it is "flat" for non professionals, and whether it is "drainage, fixing, and sealing" for professionals. The water leakage was only discovered when it rained, and the cost of rework is higher than the installation fee. Learn this set of "three checks" acceptance method, and problems can be detected on the spot after installation.

一看排水坡度：平顶棚也要有坡度，这是行规

At first glance, the drainage slope: even a flat roof shed should have a slope, as per industry regulations

雨棚不是“越平越好”，建议有≥8°的倾斜坡度才能顺畅排水。验收方法很简单：在棚面上放一个乒乓球，能自然滚向排水方向就是合格；如果球不动，说明坡度不够，下雨必然积水。积水不仅增加棚面荷载，长时间积水还会加速PC板老化、导致密封胶条失效。

A canopy is not necessarily 'the flatter the better', it must have a slope of ≥ 8 ° to drain smoothly. The acceptance method is simple: place a ping pong ball on the shed surface, and if it can naturally roll towards the drainage direction, it is qualified; If the ball doesn't move, it means the slope is not enough, and rain will inevitably cause water accumulation. Water accumulation not only increases the load on the shed surface, but also accelerates the aging of PC boards and leads to the failure of sealing strips over a long period of time.

二看固定件：膨胀螺栓深度≥60mm，这是底线

Second look at the fixing parts: the depth of the expansion bolt is ≥ 60mm, this is the bottom line

雨棚固定件是抗风的第一道防线。检查时核心看三点：一是膨胀螺栓进入墙体或地面的深度是否≥60mm（低于这个深度抗风能力大打折扣）；二是固定件间距是否≤800mm（间距过大会导致棚面受力不均）；三是连接件是否采用不锈钢材质（普通铁质件半年就锈蚀松动）。

The fixed components of the canopy are the first line of defense against wind. When checking, focus on three points: first, whether the depth of the expansion bolt entering the wall or ground is ≥ 60mm (below this depth, the wind resistance is greatly reduced); Secondly, whether the spacing between fixed components is ≤ 800mm (excessive spacing can lead to uneven stress on the shed surface); The third is whether the connecting parts are made of stainless steel material (ordinary iron parts rust and loosen after six months).

三看密封处理：玻璃胶要连续、饱满、无气泡

Three aspects of sealing treatment: Glass glue should be continuous, full, and free of bubbles

雨棚漏水，70%出在密封处。验收时检查所有接缝：PC板与骨架之间的密封胶是否连续饱满、无断点无气泡；板与板搭接处的密封条是否压紧到位；铝合金接缝处是否有专用防水垫片。用手按压密封胶，不应有松动或中空感。

The rain shelter is leaking, with 70% of it coming from the sealed area. Check all joints during acceptance: whether the sealant between the PC board and the skeleton is continuous and full, without any breaks or bubbles; Is the sealing strip at the overlap between the boards tightly pressed in place; Is there a dedicated waterproof gasket at the joint of aluminum alloy. Press the sealant with your hands, there should be no looseness or hollow feeling.

一句话总结： 雨棚验收“三看”——看坡度（≥8°）、看固定（螺栓深度≥60mm）、看密封（胶条连续饱满）。三项合格，暴雨无忧。

Summary in one sentence: The "three checks" for canopy acceptance - check the slope (≥ 8 °), check the fixation (bolt depth ≥ 60mm), and check the sealing (continuous and full rubber strip). The three items are qualified, and rainstorm is not a worry.
