六、鋼結構的連接方法

GANGJIEGOUDELIANJIEFANGFAYOUHANFENGLIANJIE、LUOSHUANLIANJIEHELIUDINGLIANJIESANZHONG。

(一)、焊縫連接

優點不削弱構件截面,節約鋼材,構造簡單,制造方便,連接剛度大,密封性能好,在一定條件下易于采用自動化作業,生產效率高。

缺點超级彩票助手焊縫附近鋼材因焊接高溫作用形成的熱影響區可能是某些部位材質變脆;焊接過程中鋼材受到分布不均勻的高溫和冷卻,使結構產生焊接殘余應力和殘余變形,對結構的承載力、剛度和使用性能有一定影響;焊接結構由于剛度大,局部裂紋一經發生很容易擴展到整體,尤其是在低溫下易發生脆斷;焊縫連接的塑性和韌性較差,施焊時可能產生缺陷,使疲勞強度降低。

(二)、螺栓連接

優點:施工工藝簡單、安裝方便,特別適用于工地安裝連接,也便于拆卸,適用于需要裝拆結構和臨時性連接。

缺點:需要在板件上開孔和拼裝時對孔,增加制造工作量,且對制造的精度要求較高;螺栓孔還使構件截面削弱,且被連接件常需相互搭接或增設輔助連接板(或角鋼),因而構造較繁且多費鋼材。

(三)、 鉚釘連接

LIUDINGLIANJIESHIJIANGYIDUANDAIYOUBANYUANXINGYUZHIDINGTOUDELIUDING,JIANGDINGGANSHAOHONGHOUXUNSUCHARULIANJIEJIANDEDINGKONGZHONG,RANHOUYONGLIUDINGQIANGJIANGLINGYIDUANYEDALIUCHENGDINGTOU,YISHILIANJIEDADAOJINGU。

優點:鉚接傳力可靠,塑性、韌性均較好,質量易于檢查和保證,可用于重型和直接承受動力荷載的結構。

缺點:鉚接工藝復雜、制造費工費料,且勞動強度高,故已基本被焊接和高強度螺栓連接所取代。
