2、3.11 作业条件 基层（找坡层）应进行隐蔽工程检查验收，合格后方可进行找平层施工。 根据设计要求的坡度，弹线、找好规矩（包括天沟、檐沟的坡度），并进 行彻底清理。3.1.2操作工艺（1）养护：找平层抹平压实后，常温时在24h后浇水养护，养护时间一般不小于7d，干燥后即可进行防水层施工。3.2防水层(SBS防水卷材3厚)沥青防水卷材外观质量项目 质量要求孔洞、硌伤 不允许露胎、涂盖不匀 不允许折纹、皱折 距卷芯1000以外，长度不大于100裂纹 距卷芯1000以外，长度不大于10裂口、缺边 边缘裂口小于20，缺边长度小于50，深度小于20每卷卷材的接头 不超过1 处，较短的一段不应小于2500

3、，接头处应加长1503.2.1作业条件(1) 卷材与胶结材料的质量、技术性能必须符合设计和施工验收规范的要求。(2) 材料进场后，应按规定抽样复验，合格后方可使用；严禁使用不合格产品。(3)铺贴防水层的基层表面必须清洁、平整、坚实、干燥，并不得有空鼓和起砂开裂等现象。(4)屋面找平层的坡度应符合设计和施工验收规范要求，并不得有积水现象。(5)所有穿过屋面的管道、预埋件、吊钩、拖拉绳、吊架子钩等应在防水层施工前做好基层处理。3.2.2施工方法(1)施工顺序：防水层施工时，应按规范规定先做好节点、附加层和屋面排水比较集中部位（如：屋面与水落口连接处、天沟、檐沟、檐口、屋面转角处、排气洞与伸出屋面管

4、道、阴阳角等特殊部位）的处理，然后由屋面最低标高处向上施工。(2)卷材铺设方法采用热熔满铺法。施工时必须注意：距屋面周边800内的防水层应满粘，保证防水层四周与基层粘结牢固，卷材与卷材之间应满粘，保证搭接严密。(3)卷材铺贴方向应符合下列规定：屋面坡度小于3%时，卷材宜平行屋脊铺贴；应顺天沟、落水口处由低向高逐条铺贴。(4) 卷材定位完重新卷好，点燃喷灯烘烤卷材底面与基层接触处，火焰与卷材之间的距离宜为 0.5米，能保证卷材表面温度达到200230使其熔化为宜，调节好火焰的大小和卷材滚动的速度使卷材表面熔化后与基层很好地粘结。不得过分加热或烧穿卷材。(5) 铺贴卷材采用搭接法时，上下层及相邻两

5、幅卷材的搭接缝应错开。热熔满铺法改性沥青防水卷材的搭接宽度应符合以下规定：长边搭接不小于80mm，短边搭接不小于80mm，相邻两幅卷材短边搭接错开应不小于500mm。(6)卷材铺贴应平整顺直，避免扭曲、过分拉紧和皱折。基层与卷材排气要充分，向横向两侧排气后方可用辊子压平粘实，不允许有翘边、脱层现象。防水层不得有裂纹、脱皮、流淌、鼓泡、露胎体和皱皮等现象，厚度应符合设计要求。(7) 檐口：檐口端头的卷材裁齐后压入凹槽内，然后将凹槽用密封材料嵌填密实。天沟、檐沟卷材铺设前，应先对水落口进行密封处理。水落口杯与竖管承插口的连接处应用密封材料嵌填密实，防止该部位在暴雨时产生倒水现象，水落口周围500m

6、m范围内用防水涂料或密封材料涂封作为附加层，水落口杯与基层接触处应留宽20mm、深20mm的凹槽，嵌填密封材料。天沟转角处应先用密封材料涂封，每边宽度不少于30mm ,干燥后再铺一层卷材作为附加层。铺设时从沟底开始，顺天沟从水落口向分水岭方向铺贴，如有纵向搭接缝，必须用密封材料封口。铺至水落口的卷材附加层应深入水落口内50mm，大面铺贴的卷材应深入水落口内100mm，并用密封材料封口，同时上面的水泥砂浆应压进来。(8)热熔封边：卷材搭接处用喷灯烘烤，火焰方向与施工人员前进方向相反，卷材接缝部位必须溢出热熔的改性沥青胶，烘烤熔化后用封边工具抹平。封边要求平滑无针眼。(9)泛水卷材铺贴前，应先进行

7、试铺，将立面卷材长度留足，先铺贴平面卷材至转角处，然后从下向上铺贴立面卷材。卷材铺贴完成后，将端头裁齐，若采用预留凹槽收头，将端头全部压入凹槽内，用压条钉压固定，再用密封材料封严，最后用水泥砂浆抹封凹槽，如无法预留凹槽，应先用带垫片钉子或金属压条钉压作盖板，盖板与立墙间用密封材料封固。其他部位应严格按规范规定做好防水卷材的收头处理。立面部位采用带砂的卷材铺贴，有利于抹灰。(10)严禁在雨天施工，五级风及其以上时不得施工，施工中途下雨时，应做好已铺卷材四周的防护工作。(11) 应做好分项工程的交接检查，未经检查验收，不得进行后续施工。每一道防水层完成后，应由质检员进行专项检查，合格后方可进行下一

8、道防水层的施工，并做好隐蔽工程验收记录。(12)检验屋面有无渗漏和积水、排水系统是否通畅，可在雨后或持续淋水2h后进行。有可能作蓄水检验的屋面宜作蓄水检验，其蓄水时间不宜小于24小时，并做好记录。3.2.3质量标准 卷材防水层所用卷材及其配套材料，必须符合设计要求。 卷材防水层不得有渗漏或积水现象。 卷材防水层在天沟、檐口、水落口、泛水、和伸出屋面管道的防水构造，必须符合设计要求。3.3屋面保温层331基本要求（1）保温层应干燥，封闭式保温层的含水率应相当于该材料在当地自然风干状态下的平衡含水率。当采用有机胶结材料时，保温层的含水率不得超过5%；当采用无机胶结材料时，保温层含水率不得超过20%

The new revision of the and , reflects the partys 18 and the eighth session of the third, the spirit of the fourth plenary session, reflecting the experience of studying

29、 and implementing the General Secretary Xi Jinping series of important speech, reflects the partys eighteen years comprehensive strictly practice. (a) revised two regulations of the party need of in based on revised, the promulgation and implementation of January 2010, to strengthen the construction

30、 of the contingent of leading cadres play an important role. But with the party to manage the party strictly administering the deepening, has not been able to fully meet the actual needs. Content is too complicated, eight prohibition, 52 are not allowed to hard to remember, and also difficult to put

31、 into practice; the second is concisely positive advocated by the lack of prohibited provisions excessive, no autonomy requirements; the third is banned terms and discipline law, both with the party discipline, disciplinary regulations repeat and Criminal law and other laws and regulations repeat; t

32、he fourth is to clean the theme is not prominent, not for the existing problems, and is narrow, only needle of county-level leading cadres above. is in 1997 based on revision, in December 2003 the promulgation and implementation, to strengthen the construction of the party play very important role.

33、Along with the development of the situation, which many provisions have been unable to fully meet the comprehensive strictly administering the practice needs. One is Ji law, more than half of the provisions and criminal law and other countries laws and regulations Repetition; two is the political di

Based on

35、the above situation, need to and the two is likely to be more relevant regulations first amendment. By revising, really put the authority of Party discipline, the seriousness in the party tree and call up the majority of Party members and cadres of the party constitution of party compasses party con
