4.8級(jí)六角頭螺栓與Q235B六角頭螺栓相比較，4.8級(jí)螺栓是要求螺栓材質(zhì)的抗拉強(qiáng)度達(dá)到400MPa，屈服比為0，煙臺(tái)不銹鋼螺栓.6，那么屈服強(qiáng)度就是400*0，煙臺(tái)不銹鋼螺栓.6=240MPa。 </p> <p> <br /> </p> <p> 對(duì)比Q235的螺栓，要求螺栓材質(zhì)的屈服強(qiáng)度大于235MPa，與4.8級(jí)螺栓是差不多的。 </p> <p> <br /> </p> <p> 因此選擇螺栓的性能等級(jí)與選擇材質(zhì)沒有太大的差別，選擇任何一種表示方法作為螺栓的技術(shù)要求都是可以的。 </p> <p> <br />

建筑結(jié)構(gòu)的主構(gòu)件的螺栓連接，一般均采用**螺栓連接。普通螺栓可重復(fù)使用，**螺栓不可重復(fù)使用。**螺栓一般用于長久連接。 </p> <p> **螺栓是預(yù)應(yīng)力螺栓,摩擦型用扭矩扳手施加規(guī)定預(yù)應(yīng)力,承壓型擰掉梅花頭。普通螺栓抗剪性能差，可在次要結(jié)構(gòu)部位使用。普通螺栓只需擰緊即可。 </p> <p> 普通螺栓一般為4.4級(jí)、4.8級(jí)、5.6級(jí)和8.8級(jí)。**螺栓一般為8.8級(jí)和10.9級(jí)，其中10.9級(jí)居多。 </p> <p> 8.8級(jí) 與8.8S 是相同等級(jí)。普通螺栓與**螺栓的受力性能與計(jì)算方法均有所區(qū)別的。**螺栓的受力首先是通過在其內(nèi)部施加預(yù)拉力P，然后在被連接件之間的接觸面上產(chǎn)生摩擦阻力來承受外荷載的，而普通螺栓則是直接承受外荷載的。 </p> <p> <br /> 螺栓檢測分為幾種類型？張家界螺栓包括什么</p><p
