style="text-indent:25px">箱形梁的加工制作說(shuō)明：18.900m樓層的箱型梁301、302、304、305、是加壓氣化爐的主要承重梁，箱形梁是由上下翼板與側(cè)腹板焊接而成，翼板由鋼板拼接而成。翼板上的對(duì)接焊縫均為II級(jí)焊縫，在整個(gè)制作過(guò)程中有較高的的質(zhì)量要求，并且每個(gè)箱形梁的翼板對(duì)接焊縫要抽查20%進(jìn)行超聲波檢查。放樣板材下料前應(yīng)綜合考慮材料規(guī)格進(jìn)行排版，盡量減少拼接及對(duì)接焊縫，上下翼板的較小拼接長(zhǎng)度不小于1m。放樣劃線時(shí)，應(yīng)清楚標(biāo)明裝配標(biāo)記、螺孔位置、加強(qiáng)板的位置方向、中心線、基準(zhǔn)線和檢驗(yàn)線，必要時(shí)應(yīng)制作樣板。注意預(yù)留制作、安裝時(shí)的焊接收縮余量、切割加工余量、安裝預(yù)留尺寸。劃線前材料的彎曲變形應(yīng)予以矯正。</p><p style="text-indent:25px">通過(guò)逐步改變箱梁內(nèi)橫隔板的數(shù)量,考查了橫隔板的設(shè)置密度與畸變的關(guān)系;并將畸變的計(jì)算結(jié)果與相同條件下按剛性扭轉(zhuǎn)、對(duì)稱彎曲和偏心荷載作用下的計(jì)算結(jié)果進(jìn)行了比較分析,得到了反映橫隔板密度對(duì)畸變效應(yīng)的影響曲線。在此基礎(chǔ)上,提出了偏心荷載作用下鋼板箱形梁的簡(jiǎn)化設(shè)計(jì)計(jì)算方法。通過(guò)分析,得到了以下初步的結(jié)論:橫隔板對(duì)箱形梁的畸變具有明顯的約束作用;畸變程度的大小與橫隔板的設(shè)置密度有密切的關(guān)系;橫隔板的設(shè)置密度是由畸變效應(yīng)決定的;即使設(shè)置了較高密度的橫隔板,也無(wú)法使畸變效應(yīng)減小到相對(duì)于剛性扭轉(zhuǎn)效應(yīng)可以忽略的程度;是否考慮畸變的影響會(huì)對(duì)箱形梁的約束扭轉(zhuǎn)分析產(chǎn)生很大的影響;對(duì)于不同的荷載形式和約束條件,橫隔板對(duì)畸變的影響效果也是不相同的; 在橫隔板設(shè)置處,畸變變形是非常微小的;對(duì)于承受集中恒荷載的箱形梁,*需在荷載作用處設(shè)置一道橫隔板就可使畸變變形減小到很小的程度。鋼箱梁既可以節(jié)約混凝土，又減輕構(gòu)件的自重，提高了跨越能力。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;
