1、某某中心医院综合楼建设项目保温工程施工方案施工单位:重庆大山建设有限公司 编 制 人: 审 核 人: 编制时间: 2011年12月30日编制依据:1、无机保温砂浆建筑保温系统应用技术规程(DBJ50-103-2010)2、广东建筑艺术设计研究院设计的节能建筑图。一、外墙保温(内墙保温)(一)施工条件:1、基层墙面应干燥并清理干净。2、施工现场环境温度和基层墙体表面温度在施工及施工后24h内不得低于5摄氏度。3、为保证施工质量,施工面应避免长时间阳光直射,应保证系统施工的连续性。4、雨天施工应采取有效措施,防止雨水冲刷墙面。(二)、配合施工条件检查、准备:1、墙体工程质量检查验收A、墙体的检查:
2、根据墙体材质,参考砌体工程施工及验收规范进行检验合格后方可实施找平抹灰。具体要求如下:(1)、使用1:25水泥砂浆找平,若混凝土及砌筑墙体平整度、垂直度状况在规范允许范围内(保温允许4mm),也可无需做找平砂浆层。可在界面砂浆的施工表面层上直接施工保温砂浆;(2)、表面强度达到0.5Mpa:(3)、平整度和垂直度要求:2米靠尺检查,差距控制在4mm以内;B、保温砂浆施工前,门、窗洞按照设计要求做好门、窗侧边水泥砂浆收头工作,且符合设计施工验收规范:C、架设的准备:按照国家验收的有关规定进行施工安全技术交底和劳动保护及防火、防毒的安全捡查:D、材料准备:所需要的材料进场后,按照相关规定登记检查,
3、并妥善贮存和管理。提前做好材料报检和送检工作;E、水电准备:依据需求配送电源及相关的水源,水质应符合用水标准:F、工具的准备:施工前的工具准备到位,工具的完好性与设备的调试;G、人员的培训:重点在于产品、工艺、施工步骤、注意事项及安全须知、安全措施及文明施工等方面。2、施工气候条件施工条件:本系统的施工24小时内,环境温度应在535摄氏度之间,严禁在大风、大雨以及阳光直射下施工。否则需采取防护措施。(三)基层面检查与处理1、基层面检查(1)、干燥度检查:基层面和找平层砂浆干燥程度、潮湿程度、固化程度。(2)、干净度检查:基层面的油污、灰尘、疏松物等影响粘结效果的异物。(3)、表面强度检查:基层
4、面砂浆的表面强度、裂缝、砂眼、空鼓等检查。(4)、平整度和垂直度检查。2、基层面处理(1)、驱除浮尘、疏松物、表面凸起物1 0 nm应铲平。(2)、钢制轻打磨:驱除油污。(3)、墙面修整处理:修补提高平整和垂直度,提高表面强度,从顶层到底层吊通线,如顶层和底层垂直度出现差异,此时必须用1:25水泥砂浆找平。并且用2m的靠尺或水平仪检测平整度,要求差距控制在4 mm范围内。(4)、基层为混凝土,空心砌块,基材无油污、无灰尘及其他松软附着物,基材表面过于干燥或表面温度超过35摄氏度,应在施工前一天用水淋湿。(5)、如果基面过度凹凸,应提前补平,以保证保温浆料层厚度均匀。(四)垂直、套方、打点、冲筋
5、、厚度控制及面砖保温工程的施工工艺:1、吊垂直线:从顶层到底层地面吊垂直线,预留出保温层和外饰面砖层的厚度,弹好控制线。2、弹好控制线后。如果顶层和底层不垂直,平整度(厚度)相差较大时,必须用1:25的水泥砂浆找平,养护后再作保温。3、打点、冲筋:用配制搅拌好的保温浆料直接做成直径为30 mm、厚度为(办公楼35;医疗综合楼30mm)的灰饼冲筋,达到找平标准。4、聚合物外墙外保温面砖饰面系统的施工工艺如下:外墙:界面砂浆保温砂浆十抗裂砂浆热镀锌电焊网十锚固件抗裂砂浆。内墙:界面砂浆保温砂浆十抗裂砂浆耐碱玻璃纤维网布。(五)保温材料搅拌及施工1、界面砂浆(1)、搅拌:界面砂浆为防水防潮包装,规格
6、:40 kg袋。界面砂浆处理材料属于粉状预混单组份界面剂。现场直接加水搅拌均匀即可施工,理论用量:15 kgm2;按每袋40 kg的界面砂浆加水1215公斤搅拌均匀,搅拌好的界面砂浆应无细小颗粒和粉团,静置5分钟后再搅拌一次。用刮刀涂于墙面,也可用滚筒滚涂于墙面:(2)、施工要点:A、必须要注意界面剂的均匀性,杜绝有些部位漏涂现象,必须要均匀。相隔1-2小时趁界面砂浆未干可进行下道工序的施工。界面剂的厚度一般宜1 mm,用量1.0-1.5kg/m2,必须作好检查验收记录;B、配好的界面砂浆必须在2小时内用完,滚涂界面砂浆时,在门洞洞口外侧、空调板、伸缩逢两侧、女儿墙、散水等部位应同时铺设翻包的
7、耐碱玻纤网格布,网格布宽度不小于1 50 mn,压埋宽度不小于50 mm,翻包宽度为1 00 mn。趁界面砂浆未干时开始作保温砂浆;2、保温砂浆搅拌及施工:(1)、搅拌:A、保温砂浆为防水防潮包装,每袋25公斤。它是单组分的材料,现场施工时只需直接加水搅拌均匀即可使用;每袋保温砂浆加水20-25 kg。B、搅拌56分钟,用手握成团,浆料柔糍无松散现象即可施工;(2)、施工要点:A、在保温砂浆施工前1 2小时用水将页岩空心砖和找平层墙面淋透,施工前23小时再将墙面淋湿;B、趁界面砂浆未干时作保温砂浆,这样确保保温砂浆不会因墙面干燥失水太快而出现开裂等现象;C、作保温砂浆时应分层施工。第一遍厚度应
8、控制在20 mm内。且必须压实,让保温层和基层结合牢固。确保保温砂浆不空鼓、不开裂、不脱落;D、第一遍保温砂浆作好养护24小时(视气温而定,只要表面发白,用手指基本按不动即可)方可做第二遍保温砂浆。保温砂浆的厚度以灰饼为准。之后应用大杠刮平、压实,养护24小时;E、配好的保温砂浆必须在4小时内用完。掉地上的砂浆必须在4小时内回收;(3)、注意事项:A、现场混料搅拌时,保温砂浆必须整包或整包的倍数进行加水搅拌,严禁将单一包装的保温砂浆分批搅拌。确保保温砂浆的水灰比例。B、由于保温砂浆在搬运过程中可能会造成分层,因此若对保温砂浆进行抽样检验时,应该对单一包装的保温砂浆进行充分混合均匀的工作,之后方
9、可抽样进行测试。C、保温砂浆在施工后24小时内避免雨淋,防止保温层被雨水冲掉,影晌质量;3、抗裂砂浆及网格布和锚固件施工要点:(1)、抗裂砂浆:抗裂砂浆为防水防潮包装,规格为25 kg/袋。为厂家预拌而制成的经聚合物改性水泥基防渗防裂的单组份砂浆。其抗裂性能好,耐水强度高、压折比柔韧度稳定,施工操作方便,现场加水搅拌均匀即可施工。抗裂砂浆中的骨料比较粗糙(3050目),正因为粗糙度较大不易产生收缩裂缝,再加上其中的纤维混合使用,形成立体、多维的网状结构,能柔性释放应力,从而消除了因温差引起的开裂。(2)、热镀锌电焊网A、热镀锌电焊网用于保温砂浆第一遍抗裂砂浆和第二遍抗裂砂浆之间,本工程应符合热
10、镀锌电焊网QB/T 3897的规定,选用12.7*12.7热镀锌电焊网,电焊网采用塑料锚栓固定在基层墙体上,锚固数量不少于6个/m2。(3)、网格布A、网格布用于聚合物外墙外保温面砖饰面系统中的抗裂砂浆层中,本工程应符合JC/T841的规定,选用孔距4*4mm单层网格布。B、抗裂砂浆浆料的配制搅拌机内加净水5 kg,再加入一袋抗裂砂浆(25 kg)。用搅拌机搅拌3分钟,静置3分钟以增加和易性,装入推车前再搅拌一次23分钟,重新搅拌时无须添加水和其他材料;C、第一遍抗裂砂浆施工1、待保温砂浆养护好后,如果温度在3035度左右时,施工抗裂砂浆前23小时应在养护好的保温砂浆面上浇一次水。2、在浇好水
11、后的保温砂浆面上抹4mm厚的抗裂砂浆。3、养护24小时。D、网格布施工:施工时宜从顶层开始沿墙面阳角处,铺设在固化后的第一遍抗裂砂浆之上。固定时应由两人配合,其中1人按住网,另一个用与膨胀钉直径相同的冲击钻头成梅花形从网中钻孔并安装膨胀钉,膨胀钉锚固于基层的深度不小于25mm。网固定后在有凸出的部位用钢丝做成V型卡子压入,网平面三角的搭接不应小于1 0mm,阴阳角处的搭接不应小于50mm,固定阴阳角网前,应先将网折成90直角,再铺贴。网平整度检验合格后再进行第二遍抗裂砂浆的施工,厚度控制在5mm,要求完全覆盖网。刮平抗裂砂浆层,用木抹搓平并拉毛。每平米锚固件的个数不小于4个。E、热镀锌电焊网施
12、工:本工程外墙为饰面砖,保温砂浆后先抹第一遍抗裂砂浆,厚度控制在23mm。根据基层尺寸裁剪热镀锌电焊网分段铺贴,热镀锌电焊网的长度最长不应超过3m,施工前将边角处得热镀锌电焊网预先折成直角。铺贴过程中不应形成网兜,网张开后应顺方向依次平整铺贴,并用塑料锚栓将其锚固于基层墙体上;不平整处应采取措施确保达到铺设要求,搭接看度不小于50mm。在窗内侧面、女儿墙、沉降缝等热镀锌电焊网收头,应用水泥钉加垫片将热镀锌电焊网固定在主体结构上。热镀锌电焊网铺贴完毕经检查合格后方可抹第二遍抗裂砂浆,并将热镀锌电焊网包裹于抗裂砂浆之中,抗裂砂浆的总厚度宜控制在8-10mm,抗裂砂浆面层应达到平整度和垂直度要求。锚
13、固件在基层的有效锚固深度不应小于25mm。F、第二遍抗裂砂浆的施工1、在铺设网面上做抗裂砂浆层,以网及锚固件刚好埋入抗裂砂浆中为最佳厚度;2、抗裂砂浆达到一定强度后应适当浇水养护;注意点:特殊部位和局部节点部位处理所有保温部位与非保温部位起头与收头部位(挑檐下口、正负零的部位等)。在界面剂施工前先预埋(用界面剂埋覆)翻包耐碱网格布,压埋宽度不小于50 mm,保温层施工完毕后,达到规定的时间后进行翻包,将耐碱网格布翻包在第一遍抗裂砂浆层上,宽度为100 mm,以便增强抗裂和抗冲击的强度,总宽度=50十保温层厚度(40)+100mm左右。保温层与非保温层起头与收头部位必须用密封膏填充,然后再进行下
14、道工序即抹抗裂砂浆的施工。3、门窗洞口处耐碱玻纤网格布加强门窗洞口处用200300的耐碱玻纤网格布加强,铺设方式为45度角方向加强。玻纤网格布压埋在抗裂砂浆中。4、节点的防水处理所有预留空洞,门窗侧边,在抗裂砂浆施工完毕,达到规定的时间后,在门窗侧边及四周涂刷一道聚合物水泥基弹性防水涂料,外圈四周压边宽度为100 mm,以杜绝水的渗透而影晌基层。预留洞口处理:当脚手架折离墙体后,对连接处的孔洞先用细石砼进行填补,然后作保温砂浆层,其他步骤的操作同护面层施工一致。(六)成品保护:(略)(七)安全技术措施1、分格线、滴水槽、门窗框、槽盒上残存砂浆应及时清理干净。2、作业时,应防止破坏已抹好的墙面,
15、门窗洞口、边、角、垛宜采取保护性措施。其它工程作业时不得污染或损坏墙面,严禁踩踏窗口。3、各构造层在凝结硬化前应防止水冲、撞击、振动。4、系统墙面完工后要妥善保护、不得玷污、磕碰、损坏。5、应遵守有关安全操作规程。(1)严格遵守各项安全管理制度和安全操作规程。(2)施工前必须对工人进行质量安全技术交底。(3)对脚手架进行全面的检查,尤其是脚手片必须满铺,确保检查合格后方可进行施工。(4)对一些连墙件等其他安全设施不得随意拆除。 重庆大山建设有限公司 2011年12月30日Employment tribunals sort out disagreements between employers
