style="text-indent:25px">不同瀝青鋪裝材料用于鋼橋面鋪裝，不僅在性能上而且在施工工藝以及在工程造價(jià)上，都有明顯的區(qū)別。從許多國(guó)家實(shí)際應(yīng)用情況來看，在使用性能和使用壽命方面，以環(huán)氧瀝青鋪裝較好，澆注式瀝青和SMA次之，普通瀝青較差。在施工工藝方面，環(huán)氧瀝青混合料拌制工藝雖不是太復(fù)雜，但對(duì)溫度、時(shí)間控制非常嚴(yán)格；澆注式瀝青工藝比較特別，需要特殊的拌制設(shè)備；SMA只是比普通瀝青路面復(fù)雜一些。在工程造價(jià)方面，如以同樣厚度相比較，則環(huán)氧瀝青鋪裝成本較高，澆注式瀝青鋪裝次之，SMA比普通瀝青費(fèi)用約增加20%～30%，但比環(huán)氧瀝青和澆注式瀝青為低。然而，環(huán)氧瀝青因強(qiáng)度高，鋪裝層因此可以減薄，減輕了自重，又有利于降低造價(jià)；澆注式瀝青鋪裝層厚度也較薄，或與普通瀝青鋪裝復(fù)合使用。北京鋼橋結(jié)構(gòu)設(shè)計(jì)橋梁一般由上部構(gòu)造、下部結(jié)構(gòu)和附屬構(gòu)造物組成。</p><div

style="text-indent:25px">鋼橋工藝裝備主要有胎型、卡具和鉆孔套樣板。胎型的功能是用其擋具來控制構(gòu)件的幾何形狀及尺寸，一般由底盤、定位擋具及托架組成，分固定和轉(zhuǎn)動(dòng)兩種形式。桁架梁的鉚接縱梁和橫梁,可在**的固定胎型組裝,用沖釘及組裝螺栓固定各料件的相對(duì)位置后，扳開擋具將構(gòu)件吊出胎型，再行鉚合。主桁桿件則可用卡具控制其截面寬度。焊接桁梁構(gòu)件或箱形梁段，可用卡具或胎型控制其各部尺寸，并用定位焊固定其料件的相對(duì)位置后，再移到轉(zhuǎn)胎內(nèi)施焊（為避免仰焊以保質(zhì)量）。鉆孔套樣板習(xí)稱機(jī)器樣板，它是在厚度較小為12毫米的鋼板上按照孔眼位置鑲嵌滲碳鋼鉆孔套而成。鉆孔套硬度高于鉆頭，其位置及內(nèi)徑尺寸精度高，用它控制鉆孔，可保證孔眼精度。近年來，數(shù)控技術(shù)已逐步應(yīng)用到鋼橋制造的放樣、焰割、制孔等工序，使鋼橋生產(chǎn)自動(dòng)化程度和產(chǎn)品質(zhì)量得到有效提高。</p><p
