 外墻保溫工程在雨季施工時應注意的事項
一、保溫材料的防護措施:
1、模塑聚苯板存儲:若工地條件允許的情況下,請將保溫板儲存至室內,或集中堆放建筑物背風向,采用遮陽網覆蓋,并用重物壓緊,避免大風將保溫板吹散,造成不必要的經濟損失。
2、網格布的存儲:應貯存在干燥通風的房屋內,使其保持良好的施工性。
3、聚合物砂漿存儲:聚合物砂漿儲存一定要注意防水、防潮。
(1)室內貯存:在工地條件允許,且現有聚合物砂漿類產品不是很多的情況下,可以將材料貯存至室內,為防止雨水天氣帶來空氣濕度的增加對材料的影響。應將室內窗口進行封堵,防止潲雨。材料堆放在離地30cm處,并用雨布覆蓋。防止因雨水天氣造成樓上積水,滲漏到貯存材料上,造成聚合物砂漿硬化。
(2)室外儲存:材料堆放,選擇地勢高的地方,周圍排水通暢,不易積水,且離地30cm以上。堆放之前,在料臺上鋪設一層雨布防潮。堆放完畢,用完整雨布覆蓋在上邊,用繩子綁扎好,用重物將雨布四周壓緊。注意天氣變化,等到晴天的時候,打開雨布進行晾曬,將雨布水分蒸發,避免水汽產生水珠,滴落聚合物砂漿上,造成硬化。
4、飾面材料和膠料貯存:放置在背陰處,且在施工完成后進行檢查,注意桶蓋是否蓋好,避免雨水進入桶內,造成后續施工質量問題。
二、施工機具注意事項:
外墻保溫施工主要采用施工吊籠,當雨天來臨時,禁止施工。并切斷吊籠電源,和覆蓋好電機。避免下雨進水造成短路,發生危險。雨后復工,要派專業人員對吊籠進行檢查,防止出現吊籠故障和危險。
三、保溫施工注意事項:
(1)密切關注天氣預報,提前預警,合理安排施工時間。
(2)大風天氣:遇有六級以上強風,不得進行高處作業。加強對工人的安全教育,并對工人安全帶、安全帽、安全繩索的使用進行嚴格檢查。
(3)雨天禁止施工。根據當天具體天氣情況,合理安排施工工序。例:防止出現防護面層剛施工完成,強度不夠,被雨水沖刷后,造成表面平整度、抹灰厚度不達標而返工的情況出現。既費時費工又費料。
四、飾面施工注意事項:
(1)遵循施工完成面,在24小時之內不會被雨水沖刷。
(2)根據風力大小,盡量不要進行噴涂類材料施工。以免造成噴涂不均勻,污染其他完成面等現象。
五、安全注意事項:
1、對施工現場所有工作人員加強安全教育培訓工作,尤其是細節方面容易忽視的地方,讓安全施工深入每一個工人心中。
2、安全檢查必須到位。對建筑物主體、腳手架、吊籃、施工用電進行經常性檢查,第一時間發現問題并及時排除,對破損處及時修復,把問題處理在萌芽狀態

the power supply of the suspension cage and cover the motor well. Avoid short circuit and danger caused by rain and water inflow. When resuming work after rain, professional personnel should be sent to inspect the suspension cage so as to prevent the occurrence of failure and danger of the suspension cage.

3. Notices for insulation construction:
(1) Pay close attention to weather forecast, give early warning and arrange construction time reasonably.
(2) Gale weather: If there is a strong wind above grade 6, no high-altitude operation is allowed. Safety education for workers should be strengthened, and the use of safety belts, safety hats and safety ropes should be strictly checked.
(3) Construction is prohibited in rainy days. According to the specific weather conditions of the day, the construction process should be arranged reasonably. Example: Prevent the appearance of protective surface layer just completed construction, the strength is not enough, after being washed by rainwater, resulting in surface smoothness, plastering thickness not up to the standard and rework. It's time-consuming, labor-consuming and material-consuming.
4. Attentions in decoration construction:
(1) Following the construction completion surface, it will not be washed by rainwater within 24 hours.
(2) According to the size of the wind, spraying materials should not be constructed as far as possible. In order to avoid uneven spraying and contamination of other finish surfaces and other phenomena.
V. Safety precautions:
1. Strengthen safety education and training for all workers on the construction site, especially in details which are easily overlooked, so that safety construction goes deep into every worker's mind.

2. Safety inspection must be in place. Regular checks are carried out on the main body of the building, scaffolding, hanging basket and construction power consumption. Problems are found and eliminated at the first time, damaged areas are repaired in time, and the problems are handled in the budding state.
