13、路与中润大道相交的南路口,东西总长136.9米,南北宽115.8米,总建筑面积36187平方米。本工程在B区G-R轴1-2层顶板及A区南楼门厅、圆弧大堂顶板均采用了混凝土(叠合箱)网梁楼盖施工工艺,板厚为350mm和550mm。一、工艺特点混凝土(叠合箱)网梁楼盖技术是一种新型的楼盖形式。楼盖由小型预制构件(混凝土叠合箱)与现浇混凝土肋梁结合成具有连续箱型截面的整体结构,箱体与肋梁共同受力。它具有预制构件工厂化加工施工质量稳定、减少施工现场劳动强度、降低环境污染等优点,也具有现浇结构整体性好的特点。其中,叠合箱由预制高强度钢筋混凝土底板、轻质材料侧板和预制高强度钢筋混凝土顶板组成。叠合箱根据位
14、置不同,可分为明箱和暗箱。网梁楼盖技术由济南坚构建筑技术有限公司和山东省城镇规划建筑设计院组织课题组进行研究开发,创造出了具有空间骨架、梁板合一、箱形断面的楼盖形式。混凝土叠合箱网梁楼盖技术于2005年7月通过了山东省建设厅鉴定委员会的科学技术成果鉴定。2005年7月获山东省建设厅山东省建设新技术新产品推广证书。新型组合式混凝土叠合箱2006年8月取得国家知识产权局实用新型专利证书,专利号:ZL2005 2 0084212.9。网梁楼盖的施工,从施工工艺到施工过程各个环节的质量控制标准均可按照现行有关现浇混凝土工程的施工规程。二、工艺原理1、网梁楼盖的基本构造1.1网梁楼盖是箱形截面的密肋楼盖
15、,由预制叠合构件“叠合箱”与后浇肋梁连接成梁板合一的整体。叠合箱由预制高强度钢筋混凝土顶板、轻质材料侧壁和预制高强度钢筋混凝土底板组成。肋梁采用普通混凝土现浇而成,与叠合箱结合成整体楼盖。网梁楼盖基本构造见下图。1.2网梁楼盖体系具有底部平整、大空腔蜂窝构造、空间受力的特性。网梁楼盖不属于现浇空心板楼盖,它的基本受力单元是大翼缘箱形肋梁。叠合箱是由复合混凝土制作的中空箱体,箱体参与结构整体受力,同时又起到肋梁模板的作用。网梁楼盖平面示意图网梁楼盖剖面示意图叠合箱示意图叠合箱钢筋与肋梁筋连接2、叠合箱的基本形式 2.1叠合箱的高度在2501400mm内任意调整,可根据不同情况进行选择。 2.2叠

17、凝土养护混凝土养护底模板拆除3.1 叠合箱施工工艺流程 3.2操作要点3.2.1叠合箱构件制作图(1)、网梁楼盖是专利技术,叠合箱构件应授权委托具有混凝土建筑预制构件施工资质的企业负责加工。(2)、叠合箱预制构件的施工质量应符合混凝土结构工程施工质量验收规范(GB50204-2002)的规定。3.2.2混凝土叠合箱网梁楼盖施工(1)、施工准备1)叠合箱预制构件进场验收:检查产品出厂合格证、试验报告。检查叠合箱的表面质量,检查有无裂缝、缺损,凡不符合质量要求的不得使用。并按设计图纸核对叠合箱的型号和规格。2)检查墙体或柱标高及轴线。墙体或柱的钢筋直径、型号、位置、连接、构造等项目。(2)、叠合箱
18、构件的吊装。1)叠合箱构件到达施工现场后应使用塔吊等起重设备进行吊装。起重设备最大幅度的起重荷载应不小于10KN。2)使用叠合箱构件专用吊装工具进行吊装。将短钢管置于板底,钢管距板外边100mm,用吊环将钢管套住,垂直起吊。开始起吊、落地时应缓慢进行,并派专人指挥。叠合箱构件吊装见图3.2.2-1。 图3.2.2-1 叠合箱构件吊装图3)叠合箱的堆放及场地要求。堆放场地应事先抄平、整实。叠合箱应按照不同型号、规格分类堆放,不允许不同板号重叠堆放。条件允许时应随到随上楼。每块叠合板在板的四角应放置垫木,上下对齐、对正、垫平、垫实。板的堆放高度宜不大于十层。(3)、铺设底板模板1)本工程采用搭设满
19、堂钢管脚手架,立杆间距1.1米,立杆底部200 mm设一道扫地杆,上部设纵横拉结杆,间距1.5米左右,满堂铺设底模板,模板采用10 mm竹胶板和4880 mm方木配制。2)网梁楼盖的跨度大于6m时,模板需要(按设计要求)起拱。如图纸无明确规定时,起拱高度按短跨尺寸的1/400考虑。3)模板支设完成应组织相关人员进行模板分项工程验收。(4)、放叠合箱位置线在已验收合格的底模板上,根据施工图纸的轴线尺寸,弹出肋梁边线(即叠合箱外边的位置线),以保证叠合箱准确就位。弹线前须复核工程轴线总尺寸,确认无误后方可弹线。叠合箱暗箱位置应用红漆做出特殊标记,防止错放箱体。(5)、粘贴密封胶条在底模板上,按照已
20、弹好的肋梁边线(叠合箱外边线)向内侧偏移30mm粘贴20mm10mm(宽厚)规格的海绵单面胶条,要求海棉胶条高压缩性、高弹性和低密度。(海绵胶条由叠合箱厂家提供)也可以粘贴15mm5mm(宽厚)规格的双面胶带。胶条应距离叠合箱外边线尺寸一致,并与模板粘贴牢固。粘贴松动部位需用小铁钉钉牢。胶条可密闭模板与底箱之间的缝隙,防止叠合箱的底板与模板之间产生漏浆。叠合箱粘贴胶条示意图见图3.2.2-2。图3.2.2-2叠合箱粘贴胶条示意图(6)、安装叠合箱底板1)仔细对照箱型布置图纸,按照叠合箱位置线进行底板布置。底板之间的间距由设计要求的肋梁宽度确定,叠合箱是受力构件,位置不同,箱体的厚度配筋也不同,
21、要严格按照箱型布置图进行摆放,防止错放箱型。2)摆放叠合箱底箱时,应按设计要求区分明箱、暗箱。明箱底板、暗箱顶板板厚为7090mm,明箱顶板、暗箱底板厚为110130mm。明、暗箱板厚示意图见图3.2.2-3。图3.2.2-3 明、暗箱板厚示意图3)就位时,应使叠合板对准所划定的叠合板位置线,慢降到位,稳定落实。箱底外边线应与肋梁边线吻合。4)摆放叠合箱底板时,应保证模板上的海绵胶条粘贴牢固,且位置正确。作业人员应注意对密封胶条的保护,不得破坏胶条。5)叠合箱与底模板之间应结合紧密,严禁漏浆。(7)、调整底板钢筋按照图纸要求,调整底板预留锚固钢筋的位置和形状,锚固筋应横平竖直,弯钩朝上。(8)
22、、绑扎肋梁钢筋1)钢筋绑扎应按图纸设计要求及钢筋施工技术规范施工。双向密肋楼板的钢筋应由设计明确纵(竖)向和横向底筋的上下位置,以免因底筋互相编织而无法施工。2)进行肋梁钢筋绑扎时,须将底板预留锚固钢筋与肋梁主筋钩锚牢固。叠合箱预留筋与肋梁主筋构造见图3.2.2-4。 图3.2.2-4 叠合箱预留筋与肋梁主筋构造3)肋梁箍筋弯折半径应严格按规范规定执行,箍筋弯弧内径满足规范规定最小半径即可,不应随意加大半径,以防肋梁主筋位移。箍筋弯折半径做法见图3.2.2-5。图3.2.2-5 肋梁箍筋弯折半径示意图4)肋梁主筋及箍筋下料时须注意图纸对钢筋保护层厚度的要求,一般要求是:侧向保护层10mm,上下
23、保护层厚25mm。5)钢筋绑扎完成应组织相关人员进行隐蔽工程验收。(9)、安装叠合箱侧壁在叠合箱底板上安装叠合箱侧壁,侧壁应安装在底箱的外槽上。侧壁尺寸应与叠合箱尺寸相符。(10)、安装叠合箱顶板1)对照箱型布置图纸,进行顶板安装,不得错放箱型。2)将叠合箱顶板预留钢筋应横平竖直,弯钩朝下,并与肋梁主筋锚固牢固。叠合箱网梁楼盖施工顺序见图3.2.2-6。图3.2.2-6 叠合箱网梁楼盖施工顺序示意图(11)、混凝土浇筑1)叠合箱安装完成,应组织有关人员对叠合箱安装进行验收。2)混凝土浇筑时,应提前对叠合箱壁板、箱顶侧壁、箱底侧壁进行洒水湿润,防止现浇混凝土失水,影响混凝土强度。3)混凝土根据设
24、计要求配制,骨料选用粒径为520mm的石子和中砂,并根据季节温差选用不同类型的减水剂。4)混凝土浇捣应垂直于主龙骨方向进行;肋梁部位采用30mm或50mm插人式振捣器振捣,严禁使用振捣器振捣叠合箱的侧壁,防止叠合箱因混凝土振捣产生位移。5)混凝土浇筑完成要防止混凝土水分过早蒸发,早期宜采用塑料薄膜等覆盖的养护方法,并按照混凝土结构工程施工质量验收规范(GB 502042002)的要求进行混凝土养护。(12)、底模板拆除1)模板的拆除对结构混凝土强度要求应符合混凝土结构工程施工质量验收规范(GB 502042002)中4.3模板拆除的规定。2)底摸拆除前须提出拆模申请,并获得批准后方可进行。3)
25、应遵循先支后拆,后支先拆;先拆不承重的模板,后拆承重部分的模板;自上而下,先拆侧向支撑,后拆竖向支撑等原则。4)模板工程作业组织,应遵循支模与拆模统一由一个作业班组进行作业。其好处是,支模就考虑拆模的方便和安全,拆模时,人员熟知情况,易找拆模关键点位,对拆模进度、安全、模板及配件的保护都有利。 5)拆除底板模板时,应避免钢架杆等重物对叠合箱的撞击。(13)、板底清理1)将叠合箱板底粘贴的海绵单面胶条(双面胶带)清除干净。2)清理叠合箱底部与板底肋梁之间渗漏的混凝土砂浆,保证混凝土边角顺直,棱角分明。3.3注意事项3.3.1为保证海绵胶条粘贴牢固,底模板应在海绵胶贴粘贴完成后,方可涂刷脱模剂。3
26、.3.2海绵胶条应与模板粘贴牢固且位置正确,确保模板不漏浆。3.3.3叠合箱明箱、暗箱位置正确,不得错放箱型。3.3.4叠合箱预留钢筋与肋梁主筋的锚固应符合混凝土结构工程施工质量验收规范(GB 502042002)的规定。(网梁楼盖图纸设计要求)3.3.5不得在板上任意凿洞,板上如需要打洞,(必须经设计单位同意)采用机械钻孔,并按设计要求做相应的加固处理。4、材料与设备主要材料与机具(见表6)表6 主要材料、设备序号设备名称设备型号单位数量用途1叠合箱底板设计尺寸M2图纸叠合箱结构2叠合箱顶板设计尺寸M2图纸叠合箱结构3叠合箱侧壁812mmM2图纸叠合箱结构4海绵单面胶条20mm10mmM防止
