橋面(mian)板(ban)采用(yong)橫(heng)(heng)梁:橫(heng)(heng)梁上有(you)(you)4組夾(jia)(jia)子,用(yong)于(yu)限制(zhi)縱梁的(de)(de)位(wei)置。兩端(duan)焊接(jie)有(you)(you)短柱(zhu),用(yong)于(yu)連接(jie)斜撐,兩端(duan)底(di)面(mian)各有(you)(you)3個凹陷。安裝橫(heng)(heng)梁時(shi),將凹陷的(de)(de)眼睛放入析架下弦桿橫(heng)(heng)梁墊板(ban)上的(de)(de)栓釘中,使橫(heng)(heng)梁在析架上就位(wei)。凹陷的(de)(de)距離與析架的(de)(de)距離相同(tong)。橫(heng)(heng)梁就位(wei)后,析架的(de)(de)距離相對固定。橫(heng)(heng)梁夾(jia)(jia)具(ju);橫(heng)(heng)梁夾(jia)(jia)具(ju)由拉(la)桿、懸梁和(he)支(zhi)撐桿三部分(fen)組成(cheng);用(yong)于(yu)固定橫(heng)(heng)梁。
