【采光顶防水设计】
采光顶的防水设计遵循“保证功能、构造合理、防排结合、优选用材”的原则，综合运用“导”、“堵”等措施，一方面利用采光屋面系统的坡度，将雨水快速排除；另一方面利用耐候密封胶对玻璃面板间的缝隙进行封堵。
[Waterproof design of daylighting roof]
The waterproof design of the daylighting roof follows the principle of "ensuring function, reasonable structure, combination of prevention and drainage, and optimization of materials", and comprehensively uses "guiding", "blocking" and other measures. On the one hand, the slope of the daylighting roof system is used to quickly drain rainwater; On the other hand, weatherproof sealant is used to seal the gap between glass panels.
合理的排水设计
本工程屋面为起伏较大的空间屋面，屋面自身形成的排水坡度较大（采光顶边部最小排水坡度设定为3%），且周边相对较低，水在重力作用下往屋面周边排，在周边设置裙边，裙边内设置排水沟，将屋面汇水排出；漏斗采光顶的底部同样设置排水沟，将漏斗采光顶汇水排出。具体操作时，为了保证屋面汇水以最快的速度排出，还需按“距离最短、最有效、最清晰”的原则对屋面进行排水区域划分。
Reasonable drainage design
The roof of this project is a large undulating space roof, the drainage slope formed by the roof itself is relatively large (the minimum drainage slope at the edge of the daylighting top is set to 3%), and the surrounding area is relatively low. The water is drained to the surrounding area of the roof under the action of gravity, and the skirt is set around, and the drainage ditch is set inside the skirt to drain the roof water; A drainage ditch is also set at the bottom of the funnel daylighting roof to drain the water from the funnel daylighting roof. During the specific operation, in order to ensure that the roof catchment is discharged at the fastest speed, the roof drainage area shall be divided according to the principle of "the shortest distance, the most effective and the clearest".

防水密封设计
本项目采光顶的防水密封设计主要是玻璃板块间的接缝密封，选用的材料为具有25级位移能力的硅酮耐候密封胶，接缝宽度为16 mm，选材原则是：保证密封胶处于拉伸或压缩状态时，仍能保持粘结性不受破坏，并具有较好的弹性回复率。
Waterproof sealing design
The waterproof and sealing design of the daylighting roof of the project is mainly the joint sealing between the glass plates. The selected material is silicone weatherproof sealant with 25 levels of displacement capacity, and the joint width is 16 mm. The principle of material selection is to ensure that the sealant can maintain the adhesion without damage when it is in the tensile or compressive state, and has a good elastic recovery rate.

对于最容易出现渗漏的不锈钢固定配件处，先在下层加设防水垫片进行加强处理，再对四周采用硅酮耐候密封胶全密封。
For the stainless steel fixed fittings that are most prone to leakage, the waterproof gasket shall be added at the lower layer for strengthening treatment, and then the silicone weatherproof sealant shall be used to seal all around.
【施工要点】
要保证采光顶的防水效果，除了进行合理的防排水设计外，还应严格控制现场施工质量。
[Key points of construction]
To ensure the waterproof effect of the daylighting roof, in addition to the reasonable waterproof and drainage design, the site construction quality should also be strictly controlled.
屋面平整度控制
采光顶屋面系统采用单层网壳支承结构，玻璃面板直接通过点式固定系统固定在单层网壳结构上，实现了玻璃面板与网壳结构之间的三维安装调节需要，进而保证了整个屋面系统平整度。
Roof flatness control
The daylighting roof system adopts the single-layer reticulated shell supporting structure, and the glass panel is directly fixed on the single-layer reticulated shell structure through the point-type fixing system, which realizes the three-dimensional installation and adjustment between the glass panel and the reticulated shell structure, thus ensuring the flatness of the entire roof system.
采光屋面系统的安装
采光穹顶和漏斗采光顶安装时，都应注意将中空玻璃的夹层面置于下表面，即使夹层玻璃破碎，也不致于形成玻璃碎片雨。
Installation of daylighting roof system
When installing the daylighting dome and funnel daylighting dome, attention should be paid to placing the interlayer surface of the insulating glass on the lower surface. Even if the interlayer glass is broken, it will not form a rain of glass fragments.
接缝密封的施工
注胶工作不能在风雨天进行，注胶面要求干净，无水、油渍、铁锈、砂浆、灰尘等；注胶面净化完成后，10~15 min内进行注胶；胶缝要求外观光滑，无扭曲变形，胶缝表面无裂纹、无杂质、无明显缺陷，无三面粘接现象。
Construction of joint sealing
The glue injection shall not be carried out in rainy days. The glue injection surface shall be clean without water, oil, rust, mortar, dust, etc; After the glue injection surface is cleaned, the glue injection shall be carried out within 10-15 minutes; The adhesive joint shall be smooth in appearance, free from distortion and deformation, and the surface of the adhesive joint shall be free from cracks, impurities, obvious defects and three-sided bonding.
