螺栓檢測(cè)分為人工和機(jī)器兩種。人工是原始也是使用為普遍的一致檢測(cè)方式。為了盡量減少不良品的流出，一般生產(chǎn)企業(yè)人員通過(guò)目視的方式對(duì)待包裝或者發(fā)貨的產(chǎn)品進(jìn)行檢驗(yàn)，以排除不良品（不良包括牙傷、混料、生銹等）。 </p> <p> <br /> </p> <p> 另一種方式為機(jī)器全自動(dòng)檢測(cè)，主要是磁粉探傷。磁粉探傷是利用螺栓缺陷處的漏磁場(chǎng)與磁粉的相互作用，針對(duì)螺栓可能存在的缺陷（如裂紋，夾渣，混料等）磁導(dǎo)率和鋼鐵磁導(dǎo)率的差異。 </p> <p> <br /> </p> <p> 磁化后這些材料不連續(xù)處的磁場(chǎng)將發(fā)生崎變，形成部分磁通泄漏處工件表面產(chǎn)生了漏磁場(chǎng)，從而吸引磁粉形成缺陷處的磁粉堆積——磁痕，在適當(dāng)?shù)墓庹諚l件下，顯現(xiàn)出缺陷位置和形狀，對(duì)這些磁粉的堆積加以觀察和解釋?zhuān)堰_(dá)到剔除不良品的目的。 </p> <p> <br /> </p><p> **度螺栓的連接形式可分為摩擦型連接、承壓型連接和張拉連接等三種。 </p> <p> 摩擦型連接在內(nèi)荷載設(shè)計(jì)值下，以連接件容之間產(chǎn)生相對(duì)滑移，作為其承載能力極限狀態(tài)；承壓型連接在荷載設(shè)計(jì)值下，以螺栓或連接件達(dá)到比較大承載能力，作為其承載能力極限狀態(tài)。承壓型連接不得用于直接承受動(dòng)力荷載的構(gòu)件連接、承受反復(fù)荷載作用的構(gòu)件連接和冷彎薄壁型鋼構(gòu)件連接。因此，在高層建筑中都是應(yīng)用摩擦型連接。摩擦型連接在環(huán)境溫度為100~150℃時(shí)，設(shè)計(jì)承載力應(yīng)降低10%。 </p> <p> <br /> 螺栓檢測(cè)分為幾種類(lèi)型？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="福州螺栓廠家供應(yīng),螺栓"

**度螺栓是用特制的扳手上緊螺帽，使螺栓產(chǎn)生巨大而又受控制的預(yù)拉力，通過(guò)螺帽和墊板，對(duì)被連接件也產(chǎn)生了同樣大小的預(yù)壓力。在預(yù)壓力作用下，沿被連接件表面就會(huì)產(chǎn)生較大的摩擦力，顯然，只要軸力小于此摩擦力，構(gòu)件便不會(huì)滑移，連接就不會(huì)受到破壞，這就是**度螺栓連接的原理。 </p>
