21、础墙回填土,两侧应同时进行,暖气沟墙未填土的一侧应加支撑,防止回填时挤歪挤裂。回填土应分层夯实,不允许向槽内灌水取代夯实。(5)回填土运输时,先将墙顶保护好,不得在墙上推车,损坏墙顶与碰撞墙体。(九)、应注意的质量问题(1)砂浆配合比不准:散装水泥与砂都要车车过磅,计量要准确,搅拌时间要达到规定的要求。(2)基础墙身位移:大放脚两侧边收退要均匀,砌到基础墙身时,要拉线找正墙的轴线与边线;砌筑时保持墙身垂直。(3)墙面不平:一砖半墙必须双面挂线,一砖墙反手挂线,舌头灰要随砌随刮平。(4)水平灰缝不平:盘角时灰缝要掌握均匀,每层砖都要与皮数杆对平,通线要绷紧穿平。砌筑时要左右照顾,避免接槎处接的高

22、低不平。(5)皮数杆不平:抄平放线时,要细致认真;钉皮数杆的木桩要牢固,防止碰撞松动。皮数杆立完后,要复验,确保皮数杆标高一致。(6)埋入砌体中的拉结筋位置不准:应随时注意正在砌的皮数,保证按皮数杆标明的位置放拉结筋,其外露部分在施工中不得任意弯折;并保证其长度符合设计要求。(7)留槎不符合要求:砌体的转角与交接处应同时砌筑,否则应砌成斜槎。(8)有高低台的基础应先砌低处,并由高处向低处搭接,如设计无要求,其搭接长度不应小于基础扩大的部分的高度。(9)砌体临时间断处的高度差过大;一般不得超过一步架的高度。二、主体砖墙砌筑(一)、施工操作工艺砂浆搅拌(二)砖浇水粘土砖必须在砌筑前一天浇水湿润,一

23、般以水侵入砖四边1、5cm 为宜,含水率为10%15%,常温施工不得用干砖上墙;雨季不得使用含水率达饱与状态的砖砌墙。(三)砂浆搅拌砂浆配合比应采用重量比,计量精度水泥为 2%,砂、灰膏控制在 5%以内,宜用机械搅拌,搅拌时间不少于 1、5min。(四)砌砖墙(1)组砌方法:砌体采用三顺一丁砌法。(2)排砖撂底(干摆砖):一般外墙第一层砖摞底时,两山墙排丁砖,前后檐纵墙排条砖。根据弹好的门窗洞口位置线,认真核对窗间墙、垛尺寸,其长度就是否符合排砖模数,如不符合模数时,可将门窗口的位置左右移动。若有破活,七分头或丁砖应排在窗口中间,附墙垛或其它不明显的部位。移动门窗口位置时,应注意暖卫立管安装及

24、门窗开启时不受影响。另外,在排砖时还要考虑到门窗口上边的砖墙合拢时也不出现破砖。所以排砖时必须做全盘考虑,前后檐墙排第一皮砖时,要考虑甩窗口后砌条砖,窗角上必须就是七分头才就是好活。文档编码:CC9S10S4T3G1 HW7P9K4M6U9 ZU10B7Y7W4H5文档编码:CC9S10S4T3G1 HW7P9K4M6U9 ZU10B7Y7W4H5文档编码:CC9S10S4T3G1 HW7P9K4M6U9 ZU10B7Y7W4H5文档编码:CC9S10S4T3G1 HW7P9K4M6U9 ZU10B7Y7W4H5文档编码:CC9S10S4T3G1 HW7P9K4M6U9 ZU10B7Y7W4H

31、7Y7W4H5多孔砖砌筑方案(3)选砖:选择棱角整齐,无弯曲、裂纹,颜色均匀,规格基本一致的砖。敲击时声音响亮,焙烧过火变色,变形的砖可用在不影响外观的内墙上。(4)盘角;砌砖前应先盘角,每次盘角不要超过五层,新盘的大角,及时进行吊、靠。如有偏差要及时修整。盘角时要仔细对照皮数杆的砖层与标高,控制好灰缝大小,使水平灰缝均匀一致。大角盘好后再复查一次,平整与垂直完全符合要求后,再挂线砌墙。(5)挂线:砌筑一砖半墙必须双面挂线,如果长墙几个人均使用一根通线,中间应设几个支线点,小线要拉紧,每层砖都要穿线瞧平,使水平缝均匀一致,平直通顺;砌一砖厚混水墙时宜用外手挂线,可照顾砖墙两面平房整,为下道工序

32、控制抹灰厚度奠定基础。(6)砌砖:砌砖宜采用一铲灰、一块砖、一挤揉的“三一”砌砖法,即满铺、满挤操作法。砌砖时砖要放平。里手高,墙面就要张;里手低,墙面就要背。砌砖一定要跟线,“上跟线,下跟棱,左右相邻要对平”。水平灰缝厚度与竖向灰缝宽度一般为10mm,但不应小于 8mm,也不应大于 12mm。为保证墙面主缝垂直,不游丁走缝,当砌完一步架高时,宜每隔 2m 水平间距,在丁砖立楞位置弹两道垂直立线,可以分段控制游丁走缝。在操作过程中,要认真进行自检,如出现有偏差,应随时纠正,严禁事后砸墙。砌筑沙浆应随搅拌随使用,一般水泥砂浆必须在3h 内用完,水泥混合砂浆必须在 4h 内用完,不得使用过夜砂浆。

33、(7)留槎:外墙转角处应同时砌筑。内外墙交接处必须留斜槎,槎子长度不应于小墙体高度的 2/3,槎子必须平直、通顺。分段位置应在变形缝或门窗口处,隔墙与墙或柱不同时砌筑时,可留阳槎加预埋拉结筋。沿墙高按设计要求每50cm 预埋 6钢筋 2 根,其埋入长度从墙留槎处算起,一般每边均不小于50cm,未端应加 90 弯钩。施工洞口也应按以上要求留水平拉结筋。(8)木砖预留孔洞与墙体拉结筋:木砖预埋时应小头在外,大头在内,数量按洞口高度决定。洞口高在1、2m 以内,每边放 2 块;高 1、22m,每块放 3 块;高 23m,每边放 4 块,预埋木砖的部位一般在洞口上边或下边四皮砖,中间均匀分布。木砖要提

34、前做好防腐处理。钢门窗安装的预留孔,硬架支模、暖卫管道,均应按设计要求预留,不得事后剔凿。墙体拉结筋的位置、规格、数量、间距均应按设计要求留置,不应错放、漏放。(9)安装过梁、梁垫:安装过梁、梁垫时,其标高、位置及型号必须准确,坐灰饱满。如坐灰厚度超过 2cm 时,要用细石混凝土铺垫,过梁安装时,两端支承点的长度应一致。(10)构造柱做法:在砌砖前,先根据设计图纸将构造柱位置进行弹线,并把构造柱插筋处理顺直。砌砖墙时,与构造柱连接处砌成马牙槎。每一个马牙槎沿高度方向的尺寸不宜超过30cm(即五皮砖)。马牙槎应先退后进。拉结筋按设计要求放置,设计无要求时,一般沿墙高 50cm 设置 2 根 6水

35、平拉结筋,每边深入墙内不应小于 1m。(五)、质量标准1、保证项目(1)砖的品种、强度等级必须符合设计要求。(2)砂浆品种及强度应符合设计要求。同品种、同强度等级砂浆各组试块抗压强度平均值不小于设计强度值,任一组试块的强度最低值不小于设计强度的75%。文档编码:CC9S10S4T3G1 HW7P9K4M6U9 ZU10B7Y7W4H5文档编码:CC9S10S4T3G1 HW7P9K4M6U9 ZU10B7Y7W4H5文档编码:CC9S10S4T3G1 HW7P9K4M6U9 ZU10B7Y7W4H5文档编码:CC9S10S4T3G1 HW7P9K4M6U9 ZU10B7Y7W4H5文档编码:C
