福州地暖保溫系統施工準備

     一、福州地(di)暖(nuan)保溫系統施工準備:
     做地(di)(di)(di)(di)(di)面(mian)(mian)(mian)(mian)(mian)保溫(wen)系統鋪設前應(ying)保證(zheng)土(tu)建地(di)(di)(di)(di)(di)面(mian)(mian)(mian)(mian)(mian)墻(qiang)體均已完工(gong),并做過基礎找平,場地(di)(di)(di)(di)(di)內無其他工(gong)種在施(shi)工(gong)。施(shi)工(gong)室內溫(wen)度(du)應(ying)該符合(he)所用(yong)管材要(yao)求合(he)理使用(yong)溫(wen)度(du),因為環境溫(wen)度(du)和管材的(de)彎曲(qu)半(ban)徑有密切關(guan)系。清掃地(di)(di)(di)(di)(di)面(mian)(mian)(mian)(mian)(mian)和墻(qiang)體,使用(yong)水平尺校對地(di)(di)(di)(di)(di)面(mian)(mian)(mian)(mian)(mian)平整度(du),1米以(yi)內高(gao)低差(cha)小(xiao)于或等于5毫米。墻(qiang)面(mian)(mian)(mian)(mian)(mian)或地(di)(di)(di)(di)(di)面(mian)(mian)(mian)(mian)(mian)凸出部(bu)分(fen)用(yong)鐵鏟鏟除(chu),用(yong)混(hun)凝(ning)土(tu)填(tian)充地(di)(di)(di)(di)(di)面(mian)(mian)(mian)(mian)(mian)坑槽(cao)。衛生間(jian)和別(bie)墅底(di)層應(ying)該做好防(fang)水層或者鋪設防(fang)潮(chao)膜。


     二、地暖專(zhuan)用邊界保溫條(tiao)施工(gong)
     鋪(pu)設邊界(jie)(jie)保(bao)(bao)(bao)溫(wen)條(tiao)(tiao)之前要清掃墻(qiang)體,保(bao)(bao)(bao)證墻(qiang)面(mian)的(de)(de)(de)平整度,避免(mian)保(bao)(bao)(bao)溫(wen)條(tiao)(tiao)在施工和(he)使(shi)用(yong)的(de)(de)(de)過程中脫落(luo)。邊界(jie)(jie)保(bao)(bao)(bao)溫(wen)條(tiao)(tiao)應該粘(zhan)貼在供暖區域內所有(you)與(yu)地面(mian)相交處的(de)(de)(de)墻(qiang)面(mian)和(he)柱面(mian)上,邊界(jie)(jie)保(bao)(bao)(bao)溫(wen)條(tiao)(tiao)要具(ju)(ju)有(you)優異的(de)(de)(de)粘(zhan)貼牢度保(bao)(bao)(bao)證其使(shi)用(yong)中不(bu)(bu)會脫落(luo)。邊界(jie)(jie)保(bao)(bao)(bao)溫(wen)條(tiao)(tiao)具(ju)(ju)有(you)8毫米的(de)(de)(de)厚度,邊界(jie)(jie)保(bao)(bao)(bao)溫(wen)條(tiao)(tiao)要具(ju)(ju)有(you)一定的(de)(de)(de)伸縮(suo)性能,保(bao)(bao)(bao)證回填層(ceng)蓄熱膨脹后起到緩(huan)沖的(de)(de)(de)作(zuo)用(yong),最(zui)大限度的(de)(de)(de)壓縮(suo)量(liang)為(wei)5毫米。切割的(de)(de)(de)擠塑板不(bu)(bu)允許替代邊界(jie)(jie)保(bao)(bao)(bao)溫(wen)條(tiao)(tiao)。邊界(jie)(jie)保(bao)(bao)(bao)溫(wen)條(tiao)(tiao)連接處應使(shi)用(yong)搭接,且搭接長(chang)度不(bu)(bu)少于3公(gong)分。
     三、 地暖專用環保擠塑板鋪設
     擠塑板(ban)(ban)在鋪(pu)(pu)設之前要保證原始地面層(ceng)的(de)平(ping)整(zheng)度(du)。擠塑板(ban)(ban)應選擇(ze)密度(du)、抗壓(ya)強度(du)、導熱系數(shu)均能達到地采暖技術規(gui)程里要求指標。常規(gui)區(qu)域鋪(pu)(pu)設擠塑板(ban)(ban)選用2公分厚度(du)即可,對于潮濕環(huan)境或者保溫性差的(de)區(qu)域應選用大于2公分的(de)厚度(du)。
     四、 地暖專用反射(she)層鋪設
     由于反(fan)射(she)膜(mo)的(de)使(shi)用環境(jing),在選(xuan)擇反(fan)射(she)膜(mo)的(de)時候應(ying)(ying)選(xuan)擇耐(nai)堿(jian)性強的(de)產品。反(fan)射(she)膜(mo)的(de)鋪(pu)設要平整,盡(jin)量減(jian)少褶皺(zhou)。反(fan)射(she)膜(mo)鋪(pu)設應(ying)(ying)遮(zhe)蓋嚴密(mi),不得有保(bao)溫(wen)板和地(di)面漏(lou)鋪(pu)現象(xiang)。反(fan)射(she)膜(mo)鋪(pu)設應(ying)(ying)注意方格整齊,方便計算地(di)暖管或(huo)發(fa)熱電(dian)纜的(de)間距。  反(fan)射(she)膜(mo)連(lian)接處也(ye)要使(shi)用鋁箔(bo)膠帶粘連(lian),避免搭接過(guo)多造成材料浪費。
     五、 地暖(nuan)專用卡丁(ding)施工
     不可(ke)使(shi)用回收料制造出來的卡(ka)釘(ding),對人(ren)體有(you)害(hai)。卡(ka)釘(ding)的材質需要(yao)滿足高(gao)強度和良(liang)好蠕變(bian)性能的基(ji)本要(yao)求(qiu)。借助卡(ka)釘(ding)槍施工的卡(ka)釘(ding)強度要(yao)求(qiu)更高(gao),可(ke)承(cheng)受機械安裝。直(zhi)線距離(li)卡(ka)釘(ding)可(ke)以(yi)每隔40-50CM卡(ka)一次,轉(zhuan)彎處確保彎曲半徑要(yao)求(qiu)應該(gai)使(shi)用5個(ge)卡(ka)丁(ding)固定(ding)。卡(ka)釘(ding)安裝時注意要(yao)筆直(zhi)卡(ka)入保溫層,切忌傾斜卡(ka)釘(ding)以(yi)免固定(ding)效(xiao)果不佳。
     六(liu)、地面管(guan)道(dao)施工
     根據設計圖紙(zhi)進行(xing)(xing)布管(guan),確定管(guan)間距和管(guan)道(dao)(dao)走(zou)向,直管(guan)安裝間距誤(wu)差小(xiao)于(yu)(yu)或(huo)等于(yu)(yu)1cm。管(guan)道(dao)(dao)鋪(pu)(pu)設施工(gong)(gong)過程(cheng)中盡(jin)量穿平底鞋。一(yi)(yi)個(ge)回(hui)路(lu)(lu)不應(ying)該出現接頭(tou),鋪(pu)(pu)設每個(ge)回(hui)路(lu)(lu)長度(du)(du)也都有限制。16x2.0mm管(guan)道(dao)(dao)一(yi)(yi)個(ge)回(hui)路(lu)(lu)最(zui)大的鋪(pu)(pu)設長度(du)(du)應(ying)小(xiao)于(yu)(yu)90m;20x2.0mm管(guan)道(dao)(dao)一(yi)(yi)個(ge)回(hui)路(lu)(lu)最(zui)大鋪(pu)(pu)設長度(du)(du)應(ying)小(xiao)于(yu)(yu)120m。施工(gong)(gong)中禁止過度(du)(du)扭曲管(guan)道(dao)(dao),管(guan)道(dao)(dao)彎曲處半(ban)徑控制在不應(ying)小(xiao)于(yu)(yu)6倍管(guan)外(wai)徑。鋪(pu)(pu)設完成后嚴禁踩踏或(huo)其他損傷管(guan)道(dao)(dao)行(xing)(xing)為,地面回(hui)填層施工(gong)(gong)中杜絕粗暴野蠻施工(gong)(gong)。
     七、伸縮縫施工(gong)
     當地面(mian)(mian)(mian)施(shi)工面(mian)(mian)(mian)積大(da)于30平方(fang)米或邊(bian)長超過6米時,應按不大(da)于6米的(de)間距設(she)置伸(shen)縮縫,每(mei)個過門處(chu)設(she)置伸(shen)縮縫,復雜房(fang)型可(ke)以劃(hua)區分割計算。伸(shen)縮縫高度是(shi)從擠塑板上(shang)邊(bian)緣到回填層的(de)上(shang)邊(bian)緣,伸(shen)縮縫設(she)置處(chu)的(de)地暖管需要加(jia)套保(bao)溫管。地面(mian)(mian)(mian)如(ru)果鋪(pu)設(she)的(de)是(shi)大(da)理石(shi)或瓷(ci)磚,伸(shen)縮縫最好設(she)置在(zai)瓷(ci)磚拼縫的(de)下(xia)面(mian)(mian)(mian)。
     八、 地暖(nuan)專用生(sheng)料(liao)帶施(shi)工
     螺(luo)紋(wen)連接(jie)處(chu)應使用(yong)生(sheng)(sheng)料(liao)(liao)帶(dai)(dai)以達到優質的密封效果。生(sheng)(sheng)料(liao)(liao)帶(dai)(dai)纏(chan)繞圈數不宜過多,防止對連接(jie)件造成損壞(huai)。地采暖專用(yong)生(sheng)(sheng)料(liao)(liao)帶(dai)(dai)其(qi)密度(du)(du)和厚(hou)度(du)(du)高于市售生(sheng)(sheng)料(liao)(liao)帶(dai)(dai),生(sheng)(sheng)料(liao)(liao)帶(dai)(dai)施工時要順時針纏(chan)繞,絲口的纏(chan)繞厚(hou)度(du)(du)一般由厚(hou)到薄。
     九、地暖專用(yong)彎管器和保溫管施工
     地(di)暖分水器(qi)(qi)距離地(di)面(mian)(mian)有一定高度(du),管道由分集水器(qi)(qi)進入地(di)面(mian)(mian)部分一般要使用保護彎管器(qi)(qi),起到固定和保護地(di)面(mian)(mian)盤管不(bu)被破壞(huai)。
切不可(ke)不用(yong)(yong)或(huo)使(shi)用(yong)(yong)金屬彎管(guan)(guan)(guan)器(qi),造成更大(da)程(cheng)度(du)(du)的(de)損傷管(guan)(guan)(guan)道,推薦使(shi)用(yong)(yong)強度(du)(du)較高(gao)的(de)塑(su)料彎管(guan)(guan)(guan)器(qi)。分(fen)水器(qi)處裸露在(zai)外的(de)供(gong)回水管(guan)(guan)(guan)道需使(shi)用(yong)(yong)保(bao)(bao)溫(wen)套(tao)管(guan)(guan)(guan)。分(fen)水器(qi)處地面下地暖管(guan)(guan)(guan)道密集,為防止(zhi)局部溫(wen)度(du)(du)過高(gao)應(ying)使(shi)用(yong)(yong)保(bao)(bao)溫(wen)套(tao)管(guan)(guan)(guan)。一般(ban)加(jia)套(tao)在(zai)供(gong)水管(guan)(guan)(guan)道上(shang),回水是否加(jia)套(tao)需根據(ju)該路管(guan)(guan)(guan)道長度(du)(du)而定(ding)。保(bao)(bao)溫(wen)套(tao)管(guan)(guan)(guan)的(de)使(shi)用(yong)(yong)長度(du)(du)至兩管(guan)(guan)(guan)之間間距大(da)于10公分(fen)處。每(mei)路管(guan)(guan)(guan)道都應(ying)該配彎管(guan)(guan)(guan)器(qi),保(bao)(bao)溫(wen)套(tao)管(guan)(guan)(guan)與之隔(ge)開使(shi)用(yong)(yong)。
     十(shi)、混凝土回填層施工
     混(hun)(hun)凝(ning)土回(hui)填層(ceng)(ceng)的(de)(de)厚度一般在3-5CM左右,最低不應(ying)小于3CM。回(hui)填層(ceng)(ceng)的(de)(de)混(hun)(hun)凝(ning)土配比應(ying)嚴格執行(xing)《普通混(hun)(hun)凝(ning)土用(yong)砂、石質(zhi)量和檢測方(fang)法標準》的(de)(de)比例標準。地暖加熱管安裝完(wan)畢(bi)且水壓試驗(yan)合(he)格后 48 小時內完(wan)成混(hun)(hun)凝(ning)土填充(chong)層(ceng)(ceng)施工(gong)。混(hun)(hun)凝(ning)土填充(chong)層(ceng)(ceng)施工(gong)中(zhong), 嚴禁使(shi)用(yong)機械振搗(dao)設備;施工(gong)人員應(ying)穿軟(ruan)底鞋,采用(yong)平頭鐵(tie)鍬(qiao)。
