貝雷鋼橋橋頭(tou)搭(da)(da)(da)(da)板(ban)(ban):橋頭(tou)搭(da)(da)(da)(da)板(ban)(ban)分有扣和無扣兩種,用(yong)于連接(jie)橋面(mian)(mian)與路面(mian)(mian),其一(yi)端(duan)搭(da)(da)(da)(da)于橋梁(liang) 后(hou)一(yi)根(gen)橫梁(liang)上,另一(yi)端(duan)搭(da)(da)(da)(da)在(zai)河岸上,如地(di)基松軟(ruan),可埋(mai)設共(gong)同枕材,搭(da)(da)(da)(da)板(ban)(ban)支承于共(gong)同枕材上。橋頭(tou)搭(da)(da)(da)(da)板(ban)(ban)與縱梁(liang)相(xiang)似,區別在(zai)于橋頭(tou)搭(da)(da)(da)(da)板(ban)(ban)的工字鋼中(zhong)(zhong)部高(gao)12厘米(mi),兩端(duan)高(gao)與縱梁(liang)高(gao)相(xiang)同(10厘米(mi)),以保持橋面(mian)(mian)平順。在(zai)彎起(qi)翼(yi)緣的下面(mian)(mian)焊有弧形支座(zuo)。如橋面(mian)(mian)與路面(mian)(mian)高(gao)差較大,可用(yong)兩節或(huo)多(duo)節搭(da)(da)(da)(da)板(ban)(ban),中(zhong)(zhong)間(jian)用(yong)橫梁(liang)支承,橫梁(liang)置(zhi)于4個(ge)搭(da)(da)(da)(da)板(ban)(ban)支座(zuo)內。
