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。深圳好的鋼橋設(shè)計(jì)哪家好把國外的優(yōu)先技術(shù)與我們自己的獨(dú)自創(chuàng)立結(jié)合起來。</p><div

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。美國的金門、韋拉扎諾海峽及英國的亨伯等不錯(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。</p><p
