29、位:北京中帝恒成建筑设计有限公司施工单位:陕西新兴建设工程有限公司监理单位:陕西鸿民项目管理咨询有限公司建设地点:西安市碑林区互助路66号主要功能:地下车库,建筑面积:25219.87,建筑结构安全等级为二级;本工程所在地抗震设防烈度为 8 度;结构抗震等级为 丙类。地下车库顶板为密肋板,采用PK免拆模板进行施工。三、PK免拆模板介绍 (一)形状:为“五面形腔体”如下图:PK免拆模板仰视图模壳仰视图PK免拆模板俯视图模壳倒立图(二)PK免拆模板搬运要求:1.人工搬运时,通常一块PK免拆模板由二人协同抬运,方法:由工人直接用手抓PK免拆模板底法兰边,协同将PK免拆模板抬起转运,要轻拿轻放,严禁抛
30、、摔,以免损坏PK免拆模板。2.吊运时,必须先用钢管扎一尺寸较PK免拆模板大的提篮,先由工人按单块搬运要求,搬入提篮内,侧立套叠排放,通常一次吊运5-9块,因客观条件限制不能侧立套叠排放,而采用正向叠摞时,不得超过5块,否则将损坏PK免拆模板。塔吊起吊时,要舒缓轻提,忌猛拉硬拽,下放时要轻柔缓慢,禁止丢摔、拖拽,以免损坏PK免拆模板。五、施工工艺及要求(一)满堂脚手架:支模架采用钢管支撑体系,钢管48,壁厚3.5mm,梁底配以一定数量的短方木;在前一层楼板面上弹出有关轴线及梁的位置,同时画出梁底立杆位置;在梁底位置架立高度适宜的立杆,下接顶托转盘以调节高度。(二)铺梁底板:梁底板铺设可采用“满
31、铺”和只铺肋梁底板两种方式进行。采用满铺方式时,与大板木模底板铺设方法相同,高程与楼板小肋梁高程相同,可采用竹胶模和组合钢模,模板表面要求平整,在小肋相交处的模板缝,用胶带封好,防止漏浆。只铺肋梁底板时,应将木模板裁制成肋梁宽+10cm的长条形,压肋梁轴线铺设在钢管上面,其它事项同“满铺”。(三)弹“三线”:“三线”即一条梁轴线和两条PK免拆模板安装控制边线。第一步根据PK免拆模板施工图在楼板底模弹主梁轴线;第二步根据PK免拆模板施工图上主梁轴线与密肋梁轴线尺寸弹密肋梁轴线,如图(1);第三步以(主梁)密肋梁轴线为标准向两边偏移距离d弹PK免拆模板边线,也就是PK免拆模板安装控制边线,如图(2
32、),其中d=密肋(主)梁宽2552。弹线时必须先弹轴线,全部完成后再弹PK免拆模板控制边线,防止“误差累积”,造成肋梁偏移或者PK免拆模板无法安装等问题。(四)PK免拆模板定位:铺排时,将“三线”拉通,以控制安放位置,接着按图纸标注型号和规格尺寸,摆放相应的PK免拆模板,安装时通常由一个或几个方向依次展开,并用铁钉将PK免拆模板固定在木模板上,如图:四、扎钢筋(一)扎梁筋:按模板上小肋梁位置线,绑扎小肋梁钢筋,短跨肋梁主筋就在长跨肋梁主筋下,肋梁交叉处,肋梁主筋要相互绑牢在一起,小肋梁钢筋锚固在主梁内不小于35d(d为肋梁主筋直径)。(二)扎面筋:面筋绑扎时可在PK模板上部按设计间距进行弹线,
33、用以确定面筋的位置;面筋应置于小肋梁的上面,面筋与PK模板之间垫砂浆垫块;钢筋要在两个方向贯通,搭接倍数符合规范和设计要求,搭接点设在肋间板中部。注意:用来扎制的梁板钢筋,在使用塔吊吊放到施工区模板上时,应直接平摊于PK免拆模板顶部,严禁在PK免拆模板与钢筋之间搁制木衬,否则将损坏PK免拆模板,且每次起吊钢筋的重量不能超过1吨,如图:五、灌注混凝土: (一)架设泵管时,无论是用钢管架还是用钢筋马凳,下面必须垫模板,而且支架必须安放到梁的钢筋上,避免PK免拆模板在受到连续冲击荷载下受到损坏。(二)在使用泵送混凝土浇筑时,施工缝可设在PK免拆模板板中部,严格控制下料厚度,以免模壳上荷载过大而导致下
34、沉甚至跌落,同时必须振捣密实,不得有空鼓;浇筑到柱头处,要在柱头原混凝土上填50mm厚与混凝土成分相同的水泥砂浆。另外,要特别注意振捣棒不得触及模壳,派专人值班,随时检查混凝土浇捣质量。(三)双向密肋板的砼骨料选用粒径为220mm的石子和中砂,并根据季节温度的差别选用不同的减水剂。(四)砼搅拌严格控制用水量,砼坍落度宜控制在60-80mm。(五)密肋梁宜采用d30mm或d50mm插入式振捣器,板面用平板振捣器,以保证混凝土质量。(六)模壳的施工荷载控制在不大于2.53.0KN/m2。(七)混凝土养护与拆模:为了防止水份过早蒸发,混凝土表面产生裂纹,混凝土浇筑完毕后宜随覆盖塑料薄膜,最迟应在混凝
35、土初凝前盖好,炎热季节应浇水加强养护。拆模时间一般按照施工规范,支撑系统的厚度大,可后拆除。六、施工注意事项(一)PK免拆模板有一定的脆性,因此不能丢、掷、碰撞,其荷载不能超过标准。存放时要套叠排放,搬运中要轻拿轻放。(二)PK免拆模板排列铺放时,均由轴线中间向两边铺放,以免出现两边的边肋不等的现象。(三)PK免拆模板与砼成为一体不需拆除,会造成梁底不直、不平、漏浆以及振捣不实、出现空鼓不易发现等问题,必须严格组织,周密部署,详细交底,跟班检查控制。(四)在浇筑混凝土时存在爆模、跑模或PK免拆模板破裂而引起的质量问题,会给装修阶段的处理造成困难。可事先检查,在支设的PK免拆模板下方察看,若有透光、漏光现象,说明PK免拆模板过薄或破损,应在浇筑砼之前进行修补加固。对浇筑过程中出现的爆模、跑模现象应及时处理,将PK免拆模板爆模、跑模处尽量顶回原位。(五)PK免拆模板安装完毕后,应进行全面质量检查,并办理预检手续。PK免拆模板支撑系统安装牢固,其允许偏差,见表1。PK免拆模板支模验收标准允许偏差 表1项次项目允许偏差(mm)检验方法1表面平整5用直尺和塞尺量2截面尺寸2-5用尺量3相邻两板表面高低差2用尺量11
