第(di) 1 章 绪论(lun)


1.1 研(yan)究背景和意义(yi)

随着我国(guo)蒸蒸日上(shang)的经济(ji)状态,各行业(ye)都在争(zheng)先恐(kong)后(hou)的寻求发(fa)展,建(jian)筑业(ye)也位列其(qi)中(zhong)。各种建(jian)筑落地而起,有中(zhong)式(shi),欧(ou)式(shi),低(di)层,中(zhong)低(di)层、高层等各种形式(shi),用于商(shang)场、居住、厂房等各种行业(ye)。

近几年,开(kai)发(fa)商(shang)为(wei)了节约施(shi)(shi)(shi)(shi)工(gong)成本,高(gao)耸(song)构筑物越来(lai)越多(duo)。在高(gao)耸(song)构筑物整个施(shi)(shi)(shi)(shi)工(gong)过程当(dang)中,较(jiao)高(gao)的施(shi)(shi)(shi)(shi)工(gong)质量、较(jiao)短的施(shi)(shi)(shi)(shi)工(gong)工(gong)期还有(you)较(jiao)少的施(shi)(shi)(shi)(shi)工(gong)成本,成为(wei)开(kai)发(fa)商(shang)和施(shi)(shi)(shi)(shi)工(gong)单位共同追求(qiu)的完美(mei)目标。

在(zai)高耸构筑物施(shi)(shi)工(gong)(gong)(gong)(gong)过(guo)(guo)程(cheng)(cheng)(cheng)中的模板工(gong)(gong)(gong)(gong)程(cheng)(cheng)(cheng)因为其(qi)(qi)(qi)搭设(she)难度(du)大、工(gong)(gong)(gong)(gong)人安全性要求(qiu)高、材料和(he)人工(gong)(gong)(gong)(gong)消(xiao)耗成(cheng)本大的缺点(dian),使(shi)得(de)滑模施(shi)(shi)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)艺和(he)爬模施(shi)(shi)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)艺凭借其(qi)(qi)(qi)各自的施(shi)(shi)工(gong)(gong)(gong)(gong)优(you)势(shi)得(de)到了广(guang)泛应用,但在(zai)施(shi)(shi)工(gong)(gong)(gong)(gong)的过(guo)(guo)程(cheng)(cheng)(cheng)当中也显露出了其(qi)(qi)(qi)缺点(dian)与不足。滑模施(shi)(shi)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)艺,见图 1-1,加快了现场(chang)施(shi)(shi)工(gong)(gong)(gong)(gong)的速度(du),大大节(jie)省了材料的消(xiao)耗。

滑模施(shi)(shi)工(gong)(gong)工(gong)(gong)艺是先将滑升(sheng)装置安(an)装就位,再(zai)进行钢筋的绑扎,再(zai)利用液压提升(sheng)装置一边提升(sheng)模板一边浇注混凝(ning)土的一种施(shi)(shi)工(gong)(gong)工(gong)(gong)艺。此(ci)种施(shi)(shi)工(gong)(gong)方法机械(xie)化程(cheng)度较高,施(shi)(shi)工(gong)(gong)速度快(kuai),以至(zhi)于节省了(le)工(gong)(gong)期,节约了(le)成本(ben)[1]。但在施(shi)(shi)工(gong)(gong)过程(cheng)中,需要对构筑物(wu)的高度进行控制(zhi),还(hai)要避免出现倾斜的状况;另外,混凝(ning)土的表(biao)面粗糙很难清理,在一定程(cheng)度上会影响施(shi)(shi)工(gong)(gong)的快(kuai)慢。

爬(pa)(pa)(pa)(pa)模(mo)施工(gong)工(gong)艺(yi),见图(tu) 1-2,凭借(jie)其自身的(de)(de)(de)(de)特(te)点,可(ke)以(yi)(yi)在没(mei)有起(qi)重机等(deng)(deng)设(she)备的(de)(de)(de)(de)情况下,依旧可(ke)以(yi)(yi)利用液压(ya)爬(pa)(pa)(pa)(pa)升的(de)(de)(de)(de)装置(zhi)进(jin)行(xing)爬(pa)(pa)(pa)(pa)升。并且在爬(pa)(pa)(pa)(pa)升的(de)(de)(de)(de)整(zheng)个过程中,由于(yu)风荷载的(de)(de)(de)(de)影响相对较(jiao)小,所以(yi)(yi)在爬(pa)(pa)(pa)(pa)升系统可(ke)以(yi)(yi)安全且稳定的(de)(de)(de)(de)进(jin)行(xing)爬(pa)(pa)(pa)(pa)升工(gong)作。它还具有了安全性能高、能够精(jing)准控(kong)制,节约成本等(deng)(deng)特(te)点,所以(yi)(yi)发展快速。而且爬(pa)(pa)(pa)(pa)模(mo)施工(gong)工(gong)艺(yi)可(ke)以(yi)(yi)保(bao)证施工(gong)后平整(zheng)的(de)(de)(de)(de)混凝土表面,避免了再次清(qing)理等(deng)(deng)繁琐工(gong)序,施工(gong)起(qi)来非(fei)常的(de)(de)(de)(de)简单。但是,爬(pa)(pa)(pa)(pa)模(mo)施工(gong)工(gong)艺(yi)比较(jiao)复杂,模(mo)板的(de)(de)(de)(de)造价比较(jiao)高。

1.2 翻模(mo)施(shi)工工艺在国内(nei)外的研究现状

随着(zhe)国(guo)外建筑技术(shu)的(de)发展,模板(ban)技术(shu)的(de)发展也有经历了(le)很长的(de)一(yi)(yi)段历史(shi)。在(zai)较早时(shi)期(qi),国(guo)外一(yi)(yi)般都使用(yong)的(de)是(shi)散(san)装木板(ban),在(zai)施(shi)工(gong)过程中(zhong),根据现场的(de)需要,将木板(ban)拼(pin)接(jie)成型。整个施(shi)工(gong)过程由于是(shi)人工(gong)操作,在(zai)时(shi)间(jian)方面就会耗损(sun)较大,人力方面也存在(zai)着(zhe)大批浪费。而且(qie),木板(ban)拆除后,将不再使用(yong),对(dui)材料也是(shi)一(yi)(yi)种(zhong)极大的(de)损(sun)失[5]。

20 世纪初,在组装式模具出现后,给模板(ban)行业(ye)带(dai)来了(le)巨大改革。设计单位可以提(ti)前根(gen)据(ju)施(shi)(shi)工(gong)现场的(de)(de)(de)(de)需(xu)要,设计模板(ban),加工(gong)厂再根(gen)据(ju)具体的(de)(de)(de)(de)尺寸(cun)进行大规(gui)模的(de)(de)(de)(de)批(pi)量(liang)生产。M.Ramesh Kannan[6]曾对传统的(de)(de)(de)(de)高耸构筑物(wu)模板(ban)施(shi)(shi)工(gong)方法进行了(le)阐述,道出古(gu)老的(de)(de)(de)(de)模板(ban)施(shi)(shi)工(gong)中存在着较大的(de)(de)(de)(de)质量(liang)和安全(quan)问题,为传统的(de)(de)(de)(de)模板(ban)施(shi)(shi)工(gong)画(hua)上了(le)句(ju)号,也为将(jiang)来的(de)(de)(de)(de)模板(ban)施(shi)(shi)工(gong)指明了(le)方向。

20 世纪 40 年代,瑞典 AB Bygging 发明了(le)一(yi)种中央控制液压滑模系(xi)统,解除了(le)施(shi)(shi)工(gong)现场只能依(yi)靠人(ren)民劳(lao)作的状态,对施(shi)(shi)工(gong)进度(du)的提高(gao)有了(le)特(te)别大(da)的帮助,也因此使得(de)滑模施(shi)(shi)工(gong)得(de)到了(le)很快的发展。故其(qi)他国家都开始推广(guang)此种工(gong)艺[7]。

20 世(shi)纪 80 年代,爬(pa)模施工技(ji)术在(zai)国(guo)外(wai)开始盛行,并(bing)得(de)到(dao)了较(jiao)为完善的(de)(de)(de)发展(zhan)。这(zhei)些发达国(guo)家(jia)研究了爬(pa)模工艺(yi)的(de)(de)(de)整个(ge)过程,从设计到(dao)施工再(zai)到(dao)拆除,形成(cheng)了一个(ge)特别(bie)完整的(de)(de)(de)产业链(lian)(lian)。并(bing)且这(zhei)个(ge)产业链(lian)(lian)全(quan)部由模板公(gong)司承担(dan),较(jiao)高的(de)(de)(de)自动化和机(ji)械化使得(de)这(zhei)些企(qi)业可以独自完成(cheng)从设计到(dao)施工的(de)(de)(de)全(quan)部内容(rong),并(bing)取得(de)了较(jiao)好的(de)(de)(de)经济效益[8-9]。

在(zai)国(guo)(guo)内,模板系统(tong)研发进(jin)度较国(guo)(guo)外(wai)相比稍微落(luo)后。在(zai) 20 世纪二三十年代我国(guo)(guo)全部使用的是手摇千斤(jin)顶来(lai)达到顶升(sheng)效果。直到 20 世纪 70 年代,我国(guo)(guo)某(mou)建筑公司成功(gong)研发了穿(chuan)心式液压千斤(jin)顶,这样才使得(de)我国(guo)(guo)的滑模施工工艺走向机械化进(jin)程。

在 20 世纪 80 年(nian)代末,我(wo)国(guo)引(yin)进了爬模施工(gong)技(ji)术(shu),极大的提高(gao)了我(wo)国(guo)模板施工(gong)时的工(gong)作(zuo)效率。后期国(guo)外爬模施工(gong)技(ji)术(shu)较为成(cheng)熟,帮助(zhu)我(wo)国(guo)建筑业有(you)了自主研(yan)发的能力,我(wo)国(guo)的爬模技(ji)术(shu)才得以继续发展。后来经过多年(nian)研(yan)究,爬模施工(gong)技(ji)术(shu)在我(wo)国(guo)高(gao)层建筑施工(gong)中(zhong)起到了不可估量(liang)的作(zuo)用。

2.1 工程概况

2.1.1 总体概况

天津某生活垃圾(ji)综合处理(li)厂是天津市一(yi)项重点(dian)民生工程。其中(zhong)的(de)高大烟囱是此项目(mu)(mu)的(de)一(yi)个(ge)重要且关(guan)键的(de)项目(mu)(mu)组成。

烟(yan)囱基础为(wei)(wei)(wei)(wei)筏板(ban)基础,筒身为(wei)(wei)(wei)(wei)矩形的钢(gang)筋(jin)混(hun)凝土(tu)抗震剪力(li)墙(qiang)结构,排烟(yan)内(nei)筒为(wei)(wei)(wei)(wei) 4 只管直(zhi)径为(wei)(wei)(wei)(wei) 2500mm 的钢(gang)内(nei)筒。烟(yan)囱高度 79.5m,平面尺(chi)寸为(wei)(wei)(wei)(wei) 10000*20600mm。烟(yan)囱剪力(li)墙(qiang)厚度为(wei)(wei)(wei)(wei)500~300。基础顶以上(shang),13.5m以下(xia)为(wei)(wei)(wei)(wei)500mm、550m;13.5m~37.5m为(wei)(wei)(wei)(wei) 450mm;37.5m~61.5 为(wei)(wei)(wei)(wei) 350mm;61.5m~77.5m 为(wei)(wei)(wei)(wei) 300mm。基础的混(hun)凝土(tu)强度和剪力(li)墙(qiang)混(hun)凝土(tu)强度均(jun)为(wei)(wei)(wei)(wei) C35。剪力(li)墙(qiang)的钢(gang)筋(jin)保护(hu)层厚度为(wei)(wei)(wei)(wei) 40mm。保温为(wei)(wei)(wei)(wei) 90mm 厚无(wu)碱超细(xi)玻璃棉。见下(xia)图 2.1-2.9。

2.2 翻(fan)模施工工艺(yi)的(de)设计理念(nian)、施工原理及(ji)特(te)点

2.2.1 翻模施工(gong)工(gong)艺的设计(ji)理念

翻模(mo)施(shi)(shi)工(gong)工(gong)艺的(de)(de)设(she)计理念(nian)便是以(yi)液(ye)压提升(sheng)设(she)备将操作平(ping)台(tai)提升(sheng),模(mo)板在跟随平(ping)台(tai)依(yi)次上(shang)升(sheng)为基础进行施(shi)(shi)工(gong)。施(shi)(shi)工(gong)流(liu)程简便,而且还可以(yi)灵活搭(da)配(pei)各种先(xian)进技(ji)术(shu),适用于(yu)我国(guo)各施(shi)(shi)工(gong)企业(ye)现(xian)有的(de)(de)设(she)备和(he)技(ji)术(shu)管理水平(ping),是一(yi)种较先(xian)进的(de)(de)高(gao)层及(ji)超高(gao)层主体施(shi)(shi)工(gong)工(gong)艺【30】。

2.2.2 翻模施工(gong)工(gong)艺的(de)施工(gong)原理

翻模(mo)(mo)(mo)施(shi)(shi)工(gong)(gong)工(gong)(gong)艺是(shi)在滑模(mo)(mo)(mo)基础上(shang)进(jin)行了(le)改(gai)进(jin),它(ta)既保留了(le)原(yuan)有(you)的(de)一部分优(you)点,但是(shi)其也拥(yong)有(you)了(le)自(zi)身(shen)独自(zi)的(de)特(te)点。其独有(you)的(de)特(te)点就是(shi):模(mo)(mo)(mo)板与(yu)混(hun)凝(ning)(ning)土之间(jian)的(de)滑动变为(wei)(wei)了(le)钢模(mo)(mo)(mo)板的(de)向上(shang)翻动,而模(mo)(mo)(mo)板与(yu)新浇(jiao)混(hun)凝(ning)(ning)土之间(jian)没有(you)任何(he)形式的(de)碰撞。在模(mo)(mo)(mo)板滑升时(shi),只需将混(hun)凝(ning)(ning)土强度控制好,不要引起支撑杆稳定系(xi)数降低和混(hun)凝(ning)(ning)土坍塌等情况发生,确保操作平台(tai)的(de)安(an)全可靠性。混(hun)凝(ning)(ning)土的(de)其他条(tiao)件如:温度、施(shi)(shi)工(gong)(gong)速度等条(tiao)件对(dui)整(zheng)个施(shi)(shi)工(gong)(gong)的(de)影(ying)响相对(dui)较小,不会(hui)在施(shi)(shi)工(gong)(gong)过(guo)程(cheng)中(zhong)(zhong)出现施(shi)(shi)工(gong)(gong)质量中(zhong)(zhong)的(de)常(chang)见问题,为(wei)(wei)整(zheng)个工(gong)(gong)程(cheng)的(de)顺(shun)利进(jin)行提供了(le)方(fang)便。

2.2.3 翻模(mo)施工工艺的特点

翻模(mo)施工工艺是在(zai)下一(yi)层(ceng)混凝土(tu)浇注(zhu)完(wan)(wan)成之后,提(ti)升钢平台。再(zai)往上一(yi)层(ceng)绑(bang)扎(zha)钢筋,焊接支撑(cheng),再(zai)利用手拉(la)葫芦提(ti)升钢模(mo)板(ban)(平台不动(dong),模(mo)板(ban)向上翻),钢模(mo)板(ban)安装完(wan)(wan)成之后,然后进行混凝土(tu)的浇注(zhu)。这(zhei)样操作有利于提(ti)高模(mo)板(ban)稳定(ding)性,也减少(shao)了脚手架体系的支撑(cheng)搭(da)设问(wen)题。不仅如(ru)此(ci),此(ci)种工艺的应(ying)用,还可以大(da)大(da)减少(shao)施工中(zhong)存在(zai)的质(zhi)量(liang)问(wen)题,创(chuang)造较大(da)的经济(ji)效益(yi)。具(ju)体而言,其具(ju)有以下特(te)点:

(1)在(zai)(zai)液(ye)压操(cao)作(zuo)平台(tai)的(de)翻模施工过程中(zhong),首先是在(zai)(zai)零米处将操(cao)作(zuo)台(tai)提(ti)前组(zu)装完成。在(zai)(zai)模板提(ti)升到相应(ying)位(wei)置之后,进行结构中(zhong)心的(de)纠(jiu)正。正是由于模板内(nei)的(de)混凝土(tu)还没有浇(jiao)注(zhu),所(suo)以纠(jiu)偏时的(de)筒壁不会出(chu)现(xian)凹(ao)凸(tu)不平的(de)质量问(wen)题,纠(jiu)偏也可以一次成功(gong)。在(zai)(zai)接下来的(de)浇(jiao)注(zhu)施工时,等到混凝土(tu)的(de)强(qiang)度到达一定程度后就可以将模板松开,此时两者是出(chu)于无摩擦状态,故混凝土(tu)的(de)拉裂问(wen)题就不复存在(zai)(zai)了。

(2)翻模(mo)(mo)施工时一次性(xing)浇注(zhu)的(de)(de)混凝土的(de)(de)高度(du)相对较高,与钢模(mo)(mo)板高度(du)一致,待强度(du)达(da)到 1.0MP 时即可进(jin)行(xing)脱模(mo)(mo),施工速(su)度(du)相对较快。而且翻模(mo)(mo)施工可根(gen)据施工需要(yao),可做到随(sui)(sui)开(kai)随(sui)(sui)停,避(bi)免了白天黑夜的(de)(de)连续施工,减少了工人过(guo)度(du)劳累的(de)(de)情况(kuang),为施工进(jin)度(du)提供了保障(zhang)。
