Bailey）工程師在1938年第二次世界大戰(zhàn)初期設計。主要的設計概念是以較少種類的單元構件，拼裝成能承載各種荷載、不同跨徑的裝配式鋼橋，且只需一般中型卡車運輸，特殊情況下并能全部以依靠人力來搭建。在第二次世界大戰(zhàn)期間，裝配式鋼橋被大量用于歐洲及遠東戰(zhàn)場，搶修橋梁或架設臨時便橋。美國于1941年從英國購買了**，制造裝配式鋼橋，命名為M1型；經過改進后（車行道加寬12%），命名為M2型。二戰(zhàn)后，許多國家引進了裝配式鋼橋，并開始廣泛應用于民用。在中國，裝配式鋼橋也得到了很大發(fā)展，并于1965年定型生產，現(xiàn)廣泛應用于**戰(zhàn)備、交通工程、市政水利工程。</p><p> 鋼橋冬季施工注意事項：1、使用鋼索吊裝鋼構件時應加防滑隔墊，與構件同時起吊的節(jié)點板，安裝人員需用的卡具等物用繩索綁扎牢固。2、編制鋼結構安裝焊接工藝，一個構件兩端不得同時進行焊接。3、安裝前清理構件表面冰、雪、霜，但不得損壞涂層。4、負溫安裝的柱子、主梁立即進行矯正，位置校正正確立即長久固定，當天安裝的構件要形成穩(wěn)定的空間體系。5、高強螺栓接頭安裝時構件摩擦面不得有積雪結冰，不得接觸泥土、油污等贓物。負溫下使用的高強螺栓須有產品合格證，復驗報告。6、負溫下鋼結構安裝質量除遵守《鋼結構工程施工及驗收規(guī)范》要求外，還應按設計要求進行檢查驗收。上部結構主要指橋跨結構和支座系統(tǒng)。</p><div

style="text-indent:25px">橋梁結構應便于制造和安裝，盡量采用優(yōu)先的丁—藝技術和施。鋼橋設計軟件公司</p><p style="text-indent:25px">鋼橋設計一般要求和原則：由于未栓合或未焊合的接觸部分的層間緊密度不能保證，容易形成細縫吸水，不易干燥，為了防止鋼梁銹蝕，鋼梁結構中不應有未栓合或未焊合的接觸部分。鋼梁構件上的小坑和凹槽容易引起積水，應該避免。同時，對于箱形結構或有可能積水的部位，應該開泄水孔等，防止由于空氣結露、漏水等原因導致積水。對于開口截面形式，應盡可能避免容易積水和灰塵堆積的構造細節(jié)。鋼橋設計一般要求和原則：為了提高鋼橋制作與安裝的工作效率，應盡可能減少構件和零件的種類，鋼結構的構件設計盡可能標準化，使同型構件能互換。鋼橋構件單元的尺寸和重量大小，應該充分考慮工廠到橋址的運輸條件、運輸能力和吊裝能力。如采用陸路運輸時，構件寬度和長度不能超過車輛和道路可能運輸?shù)妮^大尺寸。同時應該盡可能減少工地組裝或安裝的工作量，減少工地連接，加快施工速度和提高結構質量。如采用水路運輸和大型浮吊吊裝時，可以采用大型節(jié)段，甚至整孔吊裝。鋼橋設計軟件公司</p><p
