橋梁護欄(lan)模(mo)板(ban)(ban)是保證防(fang)(fang)撞橋梁護欄(lan)各部(bu)尺寸和外觀質(zhi)量的(de)基礎。模(mo)板(ban)(ban)要(yao)(yao)(yao)有一定的(de)強度和剛度，確保在施工(gong)中(zhong)不(bu)(bu)變形(xing)(xing)。因此護欄(lan)模(mo)板(ban)(ban)的(de)安裝要(yao)(yao)(yao)嚴(yan)格(ge)(ge)按標準(zhun)要(yao)(yao)(yao)求進(jin)行，確保砼(tong)施工(gong)時不(bu)(bu)出現跑(pao)模(mo)、錯(cuo)臺、變形(xing)(xing)、漏漿(jiang)，并保證砼(tong)的(de)外觀質(zhi)量。選用(yong)(yong)專用(yong)(yong)脫模(mo)劑保證砼(tong)顏色均勻，表面(mian)光(guang)滑。護欄(lan)斷(duan)縫(feng)(feng)設置于(yu)墩頂及(ji)跨中(zhong)，對(dui)于(yu)跨徑大于(yu)30m以(yi)上的(de)，可適當加設斷(duan)縫(feng)(feng)，防(fang)(fang)止砼(tong)在行車(che)荷載下的(de)應力(li)集中(zhong)砼(tong)斷(duan)裂并保證斷(duan)縫(feng)(feng)垂直整齊。斷(duan)縫(feng)(feng)采(cai)用(yong)(yong)泡沫(mo)材料斷(duan)開，端頭模(mo)板(ban)(ban)要(yao)(yao)(yao)用(yong)(yong)鋼板(ban)(ban)。模(mo)板(ban)(ban)接(jie)縫(feng)(feng)采(cai)用(yong)(yong)塑料膠帶粘貼于(yu)模(mo)板(ban)(ban)接(jie)縫(feng)(feng)處，模(mo)板(ban)(ban)之間采(cai)用(yong)(yong)螺絲(si)扣緊(jin)，模(mo)板(ban)(ban)與鋪裝層(ceng)接(jie)縫(feng)(feng)采(cai)用(yong)(yong)海(hai)綿(mian)材料進(jin)行填(tian)縫(feng)(feng)，保證接(jie)縫(feng)(feng)嚴(yan)密，不(bu)(bu)漏漿(jiang)，不(bu)(bu)污(wu)染。安裝模(mo)板(ban)(ban)時，嚴(yan)格(ge)(ge)控(kong)制錯(cuo)臺現象。
