内墙保温层抹灰技术交

底一、 施工准备 First, preparation for construction (一) 作业条件 (1) working conditions 1、 抹灰部位的主体结构分部工程均经过有关单位(如建设、设计、监理、施工单位等共同验收,并签认)。门窗框及需要预埋的管线已安装完毕,并经检查验收合格。 The project of the main structure of the plaster part shall be approved by the relevant units (such as construction, design, supervision, construction unit etc.). The door window and the pipeline that needs to be buried have been installed and checked for acceptance. 2、 抹灰用的脚手架应先搭好,架子要离开墙面200~250mm,搭好脚手板,防止落灰在地面,造成浪费。落地灰应回收利用。 2, the scaffold that the ash USES should be put together first, the shelf wants to leave metope 200 ~ 250mm, put up the foot plank, prevent to fall ash on the ground, cause waste. The ground ash should be recycled. 3、 将混凝土墙等表面凸出(爆模)部分凿平,对蜂窝、麻面、露筋、疏松部分等凿到实处,用1:2.5水泥砂浆分层补平,把外露钢筋头和铅丝头等清除掉。对于平滑的砼面应提前清理干净并进行凿毛或喷浆(喷吐)处理(喷浆后应养护2~3天),便于砂浆与砼有效的结合。 3, such as concrete wall surface protruding part (burst mode) chisel, honeycomb, pits, for, loose parts, such as cut the way, by 1:2. 5 layered filling cement mortar, get rid of exposed steel head and lead wire the first class. For a smooth concrete surface should be clean and cut hair or early spray (spray) processing (shotcrete should be maintained after 2 ~ 3 days), to facilitate the combination of mortar and concrete effectively. 4、 对于不同界面的墙体应按设计要求进行加强处理,避免抹灰面开裂。本工程要求,“混凝土与砌体接缝两侧各150mm抹灰前应加挂0.8厚9X25孔铁板网;楼梯间和人流通道的填充墙尚应采用钢丝网砂浆面层加强。” The wall of the different interface should be strengthened according to the design requirement, avoiding the dust surface cracking. The project requirements, "concrete and masonry joint on each side 150 before rendering should use 0.8 mm thick 9 x25 orifice plate mesh; stair and stream channel filled wall is wire mesh mortar should be adopted to strengthen." 5、 对于砖墙,应在抹灰前一天浇水湿透。对于加气混凝土砌块墙面,因其吸水速度较慢,应提前两天进行浇水,每天宜两遍以上。 The brick wall should be wet the day before. For the wall of the reinforced concrete block, the water is slower to absorb water and should be watered two days in advance, more than two times a day. 6、脚手眼及废弃孔洞应提前封堵,封堵前洞内杂物清理干净,浇水湿润后进行封堵;外墙应用细石砼封堵密实。 The feet and the discarded holes should be blocked in advance, the holes in the front hole should be cleared, the water will be blocked after watering. The exterior walls are sealed with fine concrete. (二) 材料要求 (2) material requirements 1、 砂浆:成品无机保温砂浆 Mortar: inorganic insulating mortar of finished products 2、 水:自来水 Water: tap water 3、 配合比:按该批无机保温砂浆说明使用 Match ratio: according to this batch of inorganic insulating mortar 二、 工艺流程 Second, process flow 基层处理→吊直、套方、找规矩→找平层→墙面冲筋(设置标筋) →做护角→抹水泥窗台板→抹底灰→喷刷界面剂→抹无机保温砂浆 →贴网格布→抹抗裂砂浆→养护 Basic level processing - hanging straight, set square, find rules - leveling layer - > metope screed (set standard steel) to do protect horn, window sill board with cement to wipe the bottom ash, spray brush to wipe the inorganic thermal insulation mortar, interfacial agent stick grid cloth to wipe the anti-crack mortar, maintenance 三、 操作方法 Three, the operation method (一)搅拌方法 (1) the stirring method 无机保温砂浆在搅拌过程中只需加洁净的清水(严禁添加任何外加剂),按浆料:水为1:1.3(砂浆稠度在70mm)左右,以适应现场施工要求为准,直接搅拌均匀后,静置5分钟后再次搅拌即可直接上墙批抹。 Inorganic insulation mortar in the process of mixing with clean water (do not add any additive), according to the pulp: water for 1 to 1. 3 (mortar consistency in about 70 mm), to meet the site construction requirements, directly after mixing evenly, let stand for 5 minutes to gently wipe directly on the wall batch again. (二)基层处理 (2) basic processing 1、抹灰部位的主体结构分部工程均经过有关单位(如建设、设计、监理、施工单位等共同验收,并签认)。门窗框及需要预埋的管线已安装完毕,并经检查验收合格。 The project of the main structure of the plaster part shall be approved by the relevant units (such as construction, design, supervision, construction unit etc.). The door window and the pipeline that needs to be buried have been installed and checked for acceptance. 2、抹灰用的脚手架应先搭好,架子要离开墙面200~250mm,搭好脚手板,防止落灰在地面,造成浪费。落地灰应回收利用。 2, the scaffold that the ash USES should be put together first, the shelf wants to leave metope 200 ~ 250mm, put up the foot plank, prevent to fall ash on the ground, cause waste. The ground ash should be recycled. 3、将混凝土墙等表面凸出(爆模)部分凿平,对蜂窝、麻面、露筋、疏松部分等凿到实处,用1:2.5水泥砂浆分层补平,把外露钢筋头和铅丝头等清除掉。 3, such as concrete wall surface protruding part (burst mode) chisel, honeycomb, pits, for, loose parts, such as cut the way, by 1:2. 5 layered filling cement mortar, get rid of exposed steel head and lead wire the first class. 4、施工前必须将基层表面的灰尘、油污处理干净;对于砖墙,应在抹灰前一天浇水湿透。对于加气混凝土砌块墙面,因其吸水速度较慢,应提前两天进行浇水,每天宜两遍以上,用水达到湿润(渗水深度8-10mm为宜)。 The dust and oil pollution of the primary surface must be cleaned before construction. The brick wall should be wet the day before. For aerated concrete block wall, because of its water absorption speed is slow, water should be done in two days in advance, should be more than twice a day, water to wet (water penetration depth 8-10 mm advisable). 5、不同墙面相接处必须进行挂金属网(150mm)加固,对平滑的砼表面要进行拉毛甩 浆(1-2mm)处理。确保保温层与基层墙体间的粘结力。 The metal mesh (150mm) must be strengthened in the contact area of different metope, and the smooth surface of concrete should be treated with a lasag-slurry (1-2mm). Ensure the bonding force between the insulation layer and the basic wall.
