**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，通過螺帽和墊板，對被連接件也產(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)件便不會滑移，連接就不會受到破壞，這就是**度螺栓連接的原理。 **度螺栓連接是靠連接件接觸面間的摩擦力來阻止其相互滑移的，為使接觸面有足夠的摩擦力，就必須提高構(gòu)件的夾緊力和增大構(gòu)件接觸面的摩擦系數(shù)。u型螺絲螺栓使用時(shí)，要注意周圍的環(huán)境。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">構(gòu)件間的夾緊力是靠對螺栓施加預(yù)拉力來實(shí)現(xiàn)的，所以螺栓必須采用**度鋼制造，這也就是稱為**度螺栓連接的原因。**度螺栓連接中，摩擦系數(shù)的大小對承載力的影響很大。試驗(yàn)表明，摩擦系數(shù)主要受接觸面的形式和構(gòu)件的材質(zhì)影響。為了增大接觸面的摩擦系數(shù)，施工時(shí)常采用應(yīng)噴砂、用鋼絲刷清理等方法對連接范圍內(nèi)構(gòu)件接觸面進(jìn)行處理。**度螺栓實(shí)際上有摩擦型和承壓型兩種。摩擦型**度螺栓承受剪力的準(zhǔn)則是設(shè)計(jì)荷載引起的剪力不超過摩擦力。承壓型**度螺栓則是以桿身不被剪壞或板件不被壓壞為設(shè)計(jì)準(zhǔn)則。</p><p style="text-indent:25px">M表示“公制，米制”螺紋。完整的螺紋標(biāo)記是由：螺紋特征代號＋尺寸代號＋公差帶代號＋及其他信息組成＋標(biāo)準(zhǔn)代號（如：對國產(chǎn)螺絲加國標(biāo)代號）1、螺紋的特征代號用字母“M”2、尺寸代號單線螺紋的尺寸代號為“公稱直徑×螺矩”。對粗牙螺紋可以省略標(biāo)注其螺矩項(xiàng)。多線螺紋的尺寸代號為“公稱直徑×Ph導(dǎo)程P螺矩”。3、公差帶代號由數(shù)字加字母表示（內(nèi)螺紋用大寫字母，外螺紋用小寫字母），如7H、6g等，應(yīng)特別指出，7H，6g等表示螺紋公差，而H7，g6表示圓柱體公差代號。4、旋合長度規(guī)定為短（用S表示）、中（用N表示）、長（用L表示）三種。一般情況下，不標(biāo)注螺紋旋合長度，其螺紋公差帶按中等旋合長度（N）確定。必要時(shí)，可加注旋合長度代號S或L，如“M20-5g6g－L”。特殊需要時(shí)，可注明旋合長度的數(shù)值，如“M20-5g6g－30”。5、左旋螺紋應(yīng)在旋合長度之后標(biāo)注“LH”。旋合長度代號與旋向代號間用“－”分開，右旋螺紋省略不注。細(xì)腰螺栓螺栓有利于受變力的聯(lián)結(jié)。</p><div

style="text-indent:25px">螺栓：機(jī)械零件，配用螺母的圓柱形帶螺紋的緊固件。由頭部和螺桿（帶有外螺紋的圓柱體）兩部分組成的一類緊固件，需與螺母配合，用于緊固連接兩個(gè)帶有通孔的零件。這種連接形式稱螺栓連接。如把螺母從螺栓上旋下，又可以使這兩個(gè)零件分開，故螺栓連接是屬于可拆卸連接。按連接的受力方式分：分普通的和有鉸制孔用的。按頭部形狀分：有六角頭的，圓頭的，方形頭的，沉頭的等等。其中外六角頭螺栓是比較常用的。一般沉頭用在要求連接的地方。螺栓之功能永遠(yuǎn)重要。上海螺絲購買</p><p
