止(zhi)(zhi)(zhi)水(shui)鋼(gang)(gang)(gang)板(ban)(ban)是工(gong)程(cheng)(cheng)(cheng)中(zhong)常(chang)用(yong)(yong)(yong)的材料，可以采(cai)用(yong)(yong)(yong)包括鋼(gang)(gang)(gang)板(ban)(ban)、銅板(ban)(ban)、合(he)金鋼(gang)(gang)(gang)板(ban)(ban)等，主要用(yong)(yong)(yong)于(yu)鋼(gang)(gang)(gang)筋(jin)混(hun)凝土(tu)結構(gou)、水(shui)壩及其它大型工(gong)程(cheng)(cheng)(cheng)。采(cai)用(yong)(yong)(yong)鋼(gang)(gang)(gang)板(ban)(ban)止(zhi)(zhi)(zhi)水(shui)帶(dai)它可改變(bian)水(shui)的滲透(tou)路(lu)徑，延長水(shui)的滲透(tou)路(lu)線。在滲漏水(shui)可能含有腐蝕成分(fen)(fen)的施工(gong)環(huan)境中(zhong)，金屬板(ban)(ban)止(zhi)(zhi)(zhi)水(shui)帶(dai)能起到一定(ding)(ding)的抗腐蝕作用(yong)(yong)(yong)。在防護工(gong)程(cheng)(cheng)(cheng)中(zhong)，采(cai)用(yong)(yong)(yong)金屬板(ban)(ban)止(zhi)(zhi)(zhi)水(shui)帶(dai)可確保工(gong)程(cheng)(cheng)(cheng)的防護效(xiao)果。金屬板(ban)(ban)止(zhi)(zhi)(zhi)水(shui)帶(dai)也(ye)常(chang)用(yong)(yong)(yong)于(yu)抗滲要求較高(gao)、且面積較小的工(gong)程(cheng)(cheng)(cheng)，如冶煉廠的澆鑄坑(keng)、電爐基(ji)坑(keng)等。鋼(gang)(gang)(gang)板(ban)(ban)橡膠止(zhi)(zhi)(zhi)水(shui)帶(dai)的斷面采(cai)用(yong)(yong)(yong)非等厚結構(gou)，分(fen)(fen)強力區和防水(shui)區，使各(ge)部分(fen)(fen)受力均勻，合(he)理。伸縮孔久(jiu)壁為平面，施工(gong)時板(ban)(ban)模夾(jia)制接(jie)(jie)觸面大，不易(yi)脫位；鋼(gang)(gang)(gang)板(ban)(ban)增設安裝(zhuang)孔與鋼(gang)(gang)(gang)筋(jin)相連接(jie)(jie)，橋梁變(bian)形(xing)縫嵌縫帶(dai)，固定(ding)(ding)牢靠不易(yi)位移(yi)。鍍鋅鋼(gang)(gang)(gang)板(ban)(ban)與混(hun)凝土(tu)的良(liang)好粘接(jie)(jie)，使防水(shui)性(xing)能更佳(jia)。

橡(xiang)(xiang)膠(jiao)(jiao)(jiao)止(zhi)(zhi)水(shui)帶(dai)(dai)規(gui)格(ge) 中(zhong)埋(mai)式止(zhi)(zhi)水(shui)帶(dai)(dai) 橡(xiang)(xiang)膠(jiao)(jiao)(jiao)止(zhi)(zhi)水(shui)帶(dai)(dai)對于變(bian)形(xing)縫大(da)的(de)(de)(de)接(jie)縫來說，問(wen)題就更為突出。采用鍍鋅(xin)鋼邊(bian)橡(xiang)(xiang)膠(jiao)(jiao)(jiao)止(zhi)(zhi)水(shui)帶(dai)(dai)，基本上可(ke)以克服(fu)純橡(xiang)(xiang)膠(jiao)(jiao)(jiao)橋式止(zhi)(zhi)水(shui)帶(dai)(dai)的(de)(de)(de)這些不足(zu)。而且這種復(fu)合式止(zhi)(zhi)水(shui)帶(dai)(dai)還具有(you)(you)雙重功(gong)能(neng)，即一方面可(ke)以延長途徑， CB型變(bian)形(xing)縫嵌縫帶(dai)(dai)，延緩滲水(shui)速度，另(ling)一方面鍍鋅(xin)鋼邊(bian)和混凝(ning)土有(you)(you)著良(liang)好的(de)(de)(de)粘附性，使止(zhi)(zhi)水(shui)帶(dai)(dai)能(neng)承受(shou)較大(da)的(de)(de)(de)拉(la)力(li)和扭力(li)，從而保證鋼邊(bian)橡(xiang)(xiang)膠(jiao)(jiao)(jiao)止(zhi)(zhi)水(shui)帶(dai)(dai)的(de)(de)(de)混凝(ning)土中(zhong)的(de)(de)(de)有(you)(you)效變(bian)形(xing)范圍內(nei)不會(hui)產(chan)生松(song)動和脫(tuo)落(luo)現象(xiang)，提高(gao)止(zhi)(zhi)水(shui)效果

止水性能

一旦與(yu)浸入的水相(xiang)接(jie)觸，其(qi)體積迅速膨脹(zhang)，變形(xing)縫嵌縫帶(dai)，達到完全止水。施工的安全性(xing)：因有(you)彈力和復原力，易(yi)適應構筑物的變形(xing)。對(dui)寬(kuan)面的適用性(xing)：可在各種(zhong)氣候和各種(zhong)構件條件下使用。優良的環保性(xing)，耐化學介質性(xing)、耐久性(xing)優良，不含有(you)害物質、不污染環境(jing)。

塑料(liao)止水(shui)帶施(shi)工(gong)方法(fa)與橡膠止水(shui)帶相同(tong)。在澆(jiao)埋(mai)時要使(shi)其與混凝土界面貼合(he)平整(zheng)，接(jie)頭部分粘接(jie)緊固(gu)，澆(jiao)埋(mai)過(guo)程中要以適當的(de)(de)力充分震(zhen)搗混凝土，使(shi)其與混凝土結(jie)合(he)良好，以獲得的(de)(de)止水(shui)效果。
