style="text-indent:25px">安裝螺栓與長久螺栓怎么區(qū)分？朔州什么是螺栓</p><p> **度螺栓的連接方式有摩擦連接、承壓連接、混合連接和并用連接和張拉回連接四種 </p> <p> （ 1 ）摩擦型連接：摩擦型**螺栓是一般常說的**螺栓，基于**螺栓緊固時(shí)產(chǎn)生的強(qiáng)大夾緊力來壓緊鋼板束，依靠接觸面間產(chǎn)生的抗剪摩擦力傳遞與螺栓垂直方向應(yīng)力的連接方法。 </p> <p> ( 2 ）承壓型連接：是在螺栓擰緊后所產(chǎn)生的抗滑移力及螺栓桿在螺孔內(nèi)和連接鋼板間產(chǎn)生的承壓力來傳遞應(yīng)力的一種連接方法。 </p> <p> ( 3 ）張拉型連接：接頭在螺栓擰緊后，鋼板間產(chǎn)生的壓力使靂板層處于密貼狀態(tài)，螺栓在軸向拉力作用下，板層間的壓力減少，外力完成由螺栓承擔(dān)。當(dāng)外力作用超過螺拴的預(yù)拉力時(shí)，板層間就互相離開，發(fā)生離間時(shí)的荷載叫做離間荷載，張拉連接其外力應(yīng)小于離間荷載。 </p> <p> ( 4 ）混合連接和并用連接：在**螺栓的接頭中，同時(shí)有幾種方法承受外力，這些連接中有**螺栓的摩擦型連接和承壓型連接并用；有**螺栓連接和焊接混用；有**螺栓和鉚釘并用等，混合連接時(shí)，一個(gè)接頭中兒種外力由各自的連接分別承受；并用連接時(shí)，一個(gè)接頭中幾種連接承受一種外力。 </p> <p> <br /> 朔州什么是螺栓</p><p
