墻身模板拼裝及加固

（1）模型(xing)(xing)連接(jie)系用(yong)(yong)U型(xing)(xing)卡(ka)或(huo)螺栓；1、路塹(qian)基(ji)礎開挖(wa)前必須放出開挖(wa)輪廓線，深(shen)齒免鑿(zao)(zao)毛(mao)(mao)帶哪里有，為加(jia)快施工(gong)(gong)進(jin)度時，可分段跳(tiao)槽開挖(wa)，遼陽深(shen)齒免鑿(zao)(zao)毛(mao)(mao)帶，每段大開挖(wa)長度不能大于。離基(ji)底(di)20~，采(cai)用(yong)(yong)人工(gong)(gong)開挖(wa)，修鑿(zao)(zao)基(ji)坑(keng)壁，鋼(gang)模板(ban)到場后(hou)，必須報(bao)請(qing)技術人員對模板(ban)尺寸進(jin)行抽檢(jian)。施工(gong)(gong)前后(hou)須加(jia)強對模板(ban)的保養和(he)修整工(gong)(gong)作(zuo)，用(yong)(yong)砂紙(zhi)或(huo)軟拋光機打(da)磨至(zhi)鋼(gang)的本來顏色（發亮），涂(tu)干(gan)凈輕機油或(huo)用(yong)(yong)薄塑料膜封住。

在(zai)運用時不(bu)要(yao)拆得(de)太早(zao)(zao)也不(bu)要(yao)拆得(de)太晚，深齒免(mian)(mian)鑿毛帶(dai)厚(hou)度多少，撤除太早(zao)(zao)的(de)話會(hui)形成(cheng)表面混凝土(tu)掉落(luo)，而撤除太晚會(hui)難以撤除。免(mian)(mian)鑿毛：有效降低鑿毛成(cheng)本，只需一(yi)粘一(yi)撕，就可以形成(cheng)凹凸(tu)面，深齒免(mian)(mian)鑿毛帶(dai)現貨，還具有易(yi)清洗的(de)優點。施(shi)工縫是指在(zai)混凝土(tu)澆(jiao)筑(zhu)(zhu)(zhu)過程中，因設計要(yao)求(qiu)或施(shi)工需要(yao)分段澆(jiao)筑(zhu)(zhu)(zhu)時，在(zai)或采用快易(yi)收(shou)口(kou)網(wang)作為先澆(jiao)筑(zhu)(zhu)(zhu)混凝土(tu)的(de)側(ce)模，即可露(lu)出混凝土(tu)原始(shi)級配紋理的(de)粗糙面。橋(qiao)梁免(mian)(mian)鑿毛止漿帶(dai)質量好。

因(yin)此可按照露(lu)出混(hun)凝土面的鋼筋(jin)外邊(bian)線(xian)(xian)確定涂抹的輪廓線(xian)(xian)。1)鋼筋(jin)間距400mm，板(ban)(ban)頂層(ceng)(ceng)鋼筋(jin)綁扎(zha)完(wan)畢后，在(zai)止水鋼板(ban)(ban)上側用短鋼筋(jin)頭與頂層(ceng)(ceng)板(ban)(ban)筋(jin)點(dian)焊連接(jie)并安裝上側模(mo)(mo)板(ban)(ban)。墻體模(mo)(mo)板(ban)(ban)安裝時(shi)，后澆(jiao)帶模(mo)(mo)板(ban)(ban)應進(jin)行獨(du)立支撐，樓板(ban)(ban)鋼筋(jin)綁扎(zha)完(wan)畢后，安裝側面封(feng)堵(du)模(mo)(mo)板(ban)(ban)，封(feng)堵(du)模(mo)(mo)板(ban)(ban)上下板(ban)(ban)邊(bian)均(jun)設馬牙槎，樓板(ban)(ban)底、頂層(ceng)(ceng)鋼筋(jin)卡在(zai)凹槽內，板(ban)(ban)底邊(bian)與樓板(ban)(ban)模(mo)(mo)板(ban)(ban)固定，
