style="text-indent:25px">鋼橋是一種橋跨結(jié)構(gòu)用鋼材建造的橋梁。1874年美國(guó)在密西西比河上建造了世界上首座大型鋼橋——圣路易斯(St.Louis)鋼拱橋，第二次世界大戰(zhàn)以后，鋼橋科學(xué)技術(shù)在**優(yōu)良鋼的冶煉，焊接技術(shù)的提高，正交異性鋼橋面板和**螺栓的應(yīng)用，以及結(jié)構(gòu)型式的多樣化等方面，有了很大的發(fā)展，促使大跨度鋼橋的普遍采用。由于鋼材強(qiáng)度高，性能優(yōu)越，表觀密度與容許應(yīng)力之比值小，故鋼橋跨越能力較大。鋼橋的構(gòu)件制造較適合工業(yè)化，運(yùn)輸與安裝均較方便，架設(shè)工期較短，破壞后易修復(fù)和更換，但鋼材易銹蝕，養(yǎng)護(hù)困難。鋼橋是用鋼材作為主要建造材料的橋梁。具有強(qiáng)度高，剛度大的特點(diǎn)，相對(duì)于混凝土橋可減小梁高和自重。由于鋼材的各向同性，質(zhì)地均勻及彈性模量大，使橋的工作情況與計(jì)算圖示假定比較符合，另外鋼橋一般采用工廠預(yù)制，工地拼接，施工周期短，加工方便且不受季節(jié)影響。但鋼橋的耐火性，耐腐蝕性差，需要經(jīng)常檢查，維修，養(yǎng)護(hù)費(fèi)用高。上部結(jié)構(gòu)主要指橋跨結(jié)構(gòu)和支座系統(tǒng)。</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(lái)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(lái)，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。橋梁，指架設(shè)在江河湖海上，使車輛行人等能順利通行的建筑物，稱為橋。北京正規(guī)鋼橋設(shè)計(jì)哪家好</p><p style="text-indent:25px">鋼橋一般用鋼板、型鋼等加工制作而成，加工工序多，工藝復(fù)雜，要求較高的技術(shù)和工廠專業(yè)化生產(chǎn)。上海鋼橋計(jì)算公司</p><p style="text-indent:25px">纜索懸吊法懸索橋的施工,通常是先架設(shè)纜索,用纜索上臨時(shí)加設(shè)的走行吊架，將加勁梁的梁段逐漸提升，懸掛在纜索垂下的吊桿上，調(diào)整位置后拼裝成整跨的加勁梁。施工時(shí)加勁梁梁段的自重，由纜索承受。美國(guó)的金門、韋拉扎諾海峽及英國(guó)的亨伯等不錯(cuò)的懸索橋（見彩圖），均用這種方法施工。瑞典阿斯克勒峽灣(Asker Fjord)鋼管拱橋（1960年）,利用同一原理提升跨度278米的管拱節(jié)段，懸吊在臨時(shí)施工的纜索下，調(diào)整位置后拼鉚成拱，整體降落到支座上。拱、梁組合結(jié)構(gòu)，也可采用此法安裝架設(shè),如日本天草二號(hào)橋（1966年）的156.8米朗格爾桁架梁，就是這樣施工的。上海鋼橋計(jì)算公司</p><p
