供應(yīng)商、國外北美木材供應(yīng)商簽訂了長期的供銷合同，從而可以更好地保證產(chǎn)品的及時供應(yīng)及質(zhì)量監(jiān)控。第2頁共１0頁南京道廣建筑模板有限公司大連中心裕景(公建）１．1工程圖片剪集二編制依據(jù)三施工方案說明3.１核心筒模板施工工程概況工程名稱:大連中心裕景(公建）核心筒工程。工程特征:大連中心裕景(公建)為Ｓ1、S2兩座筒支高層建筑，本方案配備的模板及液壓爬升架體是為澆注其內(nèi)部核心筒混凝土而設(shè)計的。其中Ｓ1核心筒地上8１層及屋頂機房夾層,高度為3６２．20ｍ,地下4層,高度為19．３０ｍ,Ｓ１核心筒總高度為３81.5０ｍ。標準層高度為3.9０m,但由于4．２ｍ的非標層也比較多，因第3頁共10頁南京道廣建筑模板有限公司大連中心裕景(公建）此模板配置為4.35m。Ｓ2核心筒地上62層及機房和屋頂機房夾層,高度為２6６.2０m,地下4層，高度為19.30m,S２核心筒總高度為2８５.5０ｍ。標準層高度為３．8０m,模板配置為３.95ｍ。模板配置:為防止?jié)仓{,每次澆筑時模板下包５０mｍ,上包１０0ｍｍ,以達到安全施工,順利澆筑混凝土的效果。但在Ｓ1、Ｓ2核心筒澆注時，有非標層高度大于標準層高度時,在澆注高度大于標準層高度不超過1.０m時,可采用模板上部配備加高節(jié)經(jīng)行澆注，在高度大于１.０m時,該層分兩次澆注,具體尺寸見詳圖~架體配置:根據(jù)工程特點,為保安全、加快施工速度及施工質(zhì)量，該工程采用ＳCS-8０液壓自爬模架體。架體特征:當SＣS-８０架體組拼完成,進入標準爬升是無需塔吊等額外的提升配置,該架體爬升速度快，爬升過程安全，可縮短工程施工工期,從而達到降低成本，安全完成施工的效果。3．2平面模板的組成模板剛度大,接長和接高均很方便,模板最高可一次澆筑十米以上。四爬模主要性能指標4.1液壓自爬模板體系的優(yōu)點:１．液壓爬?？烧w爬升，也可單榀爬升，爬升穩(wěn)定性好。2.操作方便,安全性高，可節(jié)省大量工時和材料。3.除了因為建筑結(jié)構(gòu)的要求(如墻面突然縮進或形狀突變)需要對模架改造之外,一般情況下爬模架一次組裝后，一直到頂不落地，節(jié)省了施工場地，而且減少了模板(特別是面板)的碰傷損毀。４.液壓爬升過程平穩(wěn)、同步、安全。5．提供全方位的操作平臺,施工單位不必為重新搭設(shè)操作平臺而浪費材料和勞動力。6．結(jié)構(gòu)施工誤差小,糾偏簡單，施工誤差可逐層消除。7.爬升速度快，可以提高工程施工速度(平均四天一層),最快的可達到２．5天。8（模板自爬,原地清理,大大降低塔吊的吊次。五工藝原理自爬模的頂升運動通過液壓油缸對導(dǎo)軌和爬架交替頂升來實現(xiàn)。導(dǎo)軌和爬模架互不關(guān)聯(lián),二者之間可進行相對運動。當爬模架工作時，導(dǎo)軌和爬模架都支撐在埋件支座上，第5頁共1０頁南京道廣建筑模板有限公司大連中心裕景（公建）兩者之間無相對運動。退模后立即在退模留下的爬錐上安裝受力螺栓、掛座體、及埋件支座,調(diào)整上、下?lián)Q向盒棘爪方向來頂升導(dǎo)軌,待導(dǎo)軌頂升到位,就位于該埋件支座上后,操作人員立即轉(zhuǎn)到下平臺拆除導(dǎo)軌提升后露出的位于下平臺處的埋件支座、爬錐等。在解除爬模架上所有拉結(jié)之后就可以開始頂升爬模架，這時候?qū)к壉３植粍?調(diào)整上下棘爪方向后啟動油缸，爬模架就相對于導(dǎo)軌運動，通過導(dǎo)軌和爬模架這種交替附墻,互為提升對方,爬模架即可沿著墻體上預(yù)留爬錐逐層提升。六液壓自爬模構(gòu)造液壓自爬模板體系的爬升系統(tǒng)主要包括:預(yù)埋件部份、導(dǎo)軌部份、液壓系統(tǒng)組成。6.１埋件總成液壓自爬模體系的埋件總成包括:埋件板、高強螺桿、爬錐、受力螺栓和埋件支座等。6.1.1埋件板與高強螺桿埋件板與高強螺桿連接,能使埋件具有很好的抗拉效果,同時也起到省料和節(jié)省空間的作用，因為其體積小,免去了在支模時埋件碰鋼筋的問題。埋件板大小、拉桿長度及直徑須按抗剪和抗拉設(shè)計計算確定。6.1.2爬錐、安裝螺栓爬錐和安裝螺栓用于埋件板和高強螺桿的定位,砼澆筑前，爬錐通過安裝螺栓固定在面板上。6.２受力螺栓受力螺栓是錨定總成部件中的主要受力部件，要求經(jīng)過調(diào)質(zhì)處理(達到Rc25-30),并且經(jīng)過探傷,確定無熱處理裂紋和其他原始裂紋后才允許發(fā)貨。６．３埋件支座埋件支座連接導(dǎo)軌和主梁,它受到施工活荷載、重力荷載、風(fēng)荷載等荷載的聯(lián)合作用,具有強的抗垂直力、水平力和彎矩作用。6.４導(dǎo)軌導(dǎo)軌是整個爬模系統(tǒng)的爬升軌道，它由由工字鋼１6及一組梯檔（梯檔數(shù)量依澆筑高第6頁共1０頁南京道廣建筑模板有限公司大連中心裕景(公建)度而定)組焊而成,梯檔間距22５mm，供上下軛的棘爪將載荷傳遞到導(dǎo)軌，進而傳遞到埋件系統(tǒng)上。６.5液壓爬升系統(tǒng)如下圖所示,液壓爬升系統(tǒng)包括:液壓泵、油缸、上、下?lián)Q向盒四部分。6．５.1液壓泵和油缸液壓泵和油缸向整個爬模系統(tǒng)提供升降動力。6.5．2上、下?lián)Q向盒上、下?lián)Q向盒，是爬架與導(dǎo)軌之間進行力傳遞的重要部件,改變換向盒的棘爪方向,實現(xiàn)提升爬架或?qū)к壍墓δ苻D(zhuǎn)換。七爬模安裝７.１爬模安裝爬升流程混凝土澆筑完后?拆模后移?安裝附裝置?提升導(dǎo)軌?爬升架體?綁扎鋼筋?模板清理刷脫模劑?埋件固定模板上?合模?澆筑混凝土預(yù)埋件安裝預(yù)埋件安裝,
