style="text-indent:25px">工廠在接受設計圖紙后，首先要根據(jù)可以采購到的各種原材料尺寸、工廠的加工能力和運輸條件等，繪制鋼結(jié)構(gòu)單元和構(gòu)件圖，即工廠加工（shopdrawing）。加工圖考慮預拱度、制作安裝變形等影響，說明加工工藝，并得到設計方和業(yè)主的認可。其次，工廠需要根據(jù)加工圖要求繪制組成鋼橋各部件的零件圖（partsdrawing）。零件圖是工廠作樣、號料和各種制作數(shù)控機床控制數(shù)據(jù)的依據(jù)，需要考慮鋼橋加工制作與安裝過程中各種變形等影響和焊縫、切割余量等要求。</p><p

style="text-indent:25px">幾種鋼橋面鋪裝的比較：編輯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上，都有明顯的區(qū)別。從許多國家實際應用情況來看，在使用性能和使用壽命方面，以環(huán)氧瀝青鋪裝比較好，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雜，但對溫度、時間控制非常嚴格；澆注式瀝青工藝比較特別，需要特殊的拌制設備；SMA 只是比普通瀝青路面復雜一些。在工程造價方面，如以同樣厚度相比較，則環(huán)氧瀝青鋪裝成本比較高，澆注式瀝青鋪裝次之，SMA 比普通瀝青費用約增加20 % ～30 % ，但比環(huán)氧瀝青和澆注式瀝青為低。然而，環(huán)氧瀝青因強度高，鋪裝層因此可以減薄，減輕了自重，又有利于降低造價；澆注式瀝青鋪裝層厚度也較薄，或與普通瀝青鋪裝復合使用。韌性、延性好，可提高抗震性能。上海鋼橋設計深化公司</p><p

style="text-indent:25px">橋梁設計基本原則及要求：橋梁設計必須遵照適用、經(jīng)濟、安全和美觀的基本原則進行，必須考慮下述各項要求。1．使用上的要求。橋梁必須適用。要有足夠的承載和泄洪能力，能保證車輛和行人的安全暢通；既滿足當前的要求，又照顧今后的發(fā)展，既滿足交通運輸本身的需要，也要兼顧其它方面的要求；在通航河道上，應滿足航運的要求；靠近城市、村鎮(zhèn)、鐵路及水利設施的橋梁還應結(jié)合有關(guān)方面的要求，考慮綜合利用。建成的橋梁要保證使用年限，并便于檢查和維護。2．經(jīng)濟上的要求。橋梁設計應體現(xiàn)經(jīng)濟上的合理性。一L刀設計必須經(jīng)過洋細周密的技術(shù)經(jīng)濟比較，使橋梁的總造價和材料等的消耗為較小，在使用期間養(yǎng)護維修費用較省，并且經(jīng)久耐用。另外，橋梁設計還應滿足快速施工的要求，縮短工期不僅能降低施丁費用，而且盡早通車在運輸上將帶來很大的經(jīng)濟效益。廣州正規(guī)鋼橋繪圖軟件企業(yè)</p><p
