屋面工程应根据工程特点、地区自然条件等,按照屋面防水等级的设防要求,进行防水构造设计,重要部位应有详图;对屋面保温层的厚度,应通过计算确定。屋面防水工程施工前应先对基层进行检查和清理,发现薄弱环节先行补强,经检查合格后方可进行上面防水层的施工。屋面防水工程可用小锤子敲墙面和地面,如果发现清脆和的空声,意味着里面有空鼓,需要把空鼓部分全部敲掉。保持清洁,清扫后存在于缝隙、阴角处的尘埃用压缩空气吹净。
The waterproof structure design of roof works shall be carried out according to the engineering characteristics, regional natural conditions and the fortification requirements of roof waterproof grade, and the important parts shall be provided with detailed drawings; The thickness of roof insulation layer shall be determined through calculation. Before the construction of roof waterproof works, the base course shall be inspected and cleaned, and the weak links found shall be reinforced first. The construction of the upper waterproof layer can be carried out only after passing the inspection. The roof waterproof works can be knocked on the wall and ground with a small hammer. If a crisp and empty sound is found, it means that there is an empty drum inside, and all the empty drums need to be knocked off. Keep clean. After cleaning, the dust existing in the gap and internal corner shall be blown away with compressed air.
不合格的材料,不得在屋面工程中使用。只有保持表面法净,才能保证防水涂料渗进到水泥砂浆内部,加强防水涂料和基层粘接,提高防水能力。屋面工程完工后,应按有关规定对细部构造、接缝、保护层等进行外观检验,并应进行淋水或蓄水检验。屋面的保温层和防水层严禁在雨天、雪天和五级风及其以上时施工。施工环境气温宜符合要求。
Unqualified materials shall not be used in roof engineering. Only by keeping the surface clean can we ensure that the waterproof coating seeps into the cement mortar, strengthen the bonding between the waterproof coating and the base course, and improve the waterproof ability. After the completion of the roof works, the detailed structure, joints, protective layer, etc. shall be visually inspected according to relevant regulations, and the watering or water storage inspection shall be carried out. The thermal insulation layer and waterproof layer of the roof shall not be constructed in rainy days, snowy days, grade 5 wind and above. The temperature of construction environment should meet the requirements.
雨雪天气或预计在防水层施工期中有雨、雪时,就不应进行防水层的施工,以免雨、雪破坏巳施工好的防水层,失去防水效果。霜、雾天或大气湿度过大时,会使基层的含水率大,对要求基层含水率较低的防水材料,如卷材和涂料就不能进行施工。南通屋顶防水层完工后,不得在其上凿孔打洞或重物冲击。如果在防水层施工时遇到雨雪,则需要立即作好保护工作,如果是卷材防水层,巳完成的卷材周边要用密封材料封固,防止雨水浸入。
In rainy and snowy weather or when rain and snow are expected during the construction period of the waterproof layer, the construction of the waterproof layer shall not be carried out, so as to avoid rain and snow damaging the constructed waterproof layer and losing the waterproof effect. When frost, fog or atmospheric humidity is too high, the moisture content of the base course will be large. Waterproof materials requiring low moisture content of the base course, such as coiled materials and coatings, cannot be constructed. After the completion of the waterproof layer of Nantong roof, holes shall not be drilled or impacted by heavy objects. If rain and snow are encountered during the construction of the waterproof layer, it is necessary to protect it immediately. If it is a coiled material waterproof layer, the periphery of the completed coiled material shall be sealed with sealing materials to prevent the immersion of rain.
