style="text-indent:25px">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。**螺栓一般用于長效連接。**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。普通螺栓一般為4.4級、4.8級、5.6級和8.8級。**螺栓一般為8.8級和10.9級，其中10，晉德螺栓，晉德螺栓.9級居多，晉德螺栓。8.8級與8.8S是相同等級。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。螺栓的螺紋可與螺帽結(jié)合。晉德螺栓</p><div

style="text-indent:25px">螺栓形狀一般沉頭用在要求連后表面光滑沒突起的地方，因?yàn)槌令^可以擰到零件里。圓頭也可以擰進(jìn)零件里。方頭的擰緊力可以大些，但是尺寸很大。另外為了滿足安裝后鎖緊的需要，有頭部有孔的，桿部有孔的，這些孔可以使螺栓受振動時不至松脫。有的螺栓沒螺紋的光桿要做細(xì)，叫細(xì)腰螺栓。這種螺栓有利于受變力的聯(lián)結(jié)。鋼結(jié)構(gòu)上有**的**度螺栓，頭部會做大些，尺寸也有變化。另外有特殊用處的：T形槽螺栓用，機(jī)床夾具上用的較多，形狀特殊，頭部兩側(cè)要切掉。地腳螺栓，用于機(jī)器和地面連接固定的，有很多種形狀。U形螺栓，如前述。等等。還有焊接用的**螺柱，一頭有螺紋一頭沒，可以焊在零件上，另一邊直接擰螺母。六角螺絲供應(yīng)螺栓用于兩種物體的連接。</p><div

style="text-indent:25px">法蘭螺栓(GB5787/DIN6921)的外表看上去和一般的普通六角頭螺栓的區(qū)別并不是很大，但是還是有著一定的區(qū)別的，例如六角法蘭面螺栓的頭部就是由六角頭和法蘭面兩部分組成的，這也是和普通六角頭螺栓的根本的區(qū)別。因?yàn)樗倪@種結(jié)構(gòu)，所以其“支撐面積與應(yīng)力面積字比值”要比普通六角頭螺栓更大一些，也是因此六角法蘭面螺栓所能夠承受的預(yù)緊力也更好，也就意味著它具有更強(qiáng)的防松性能，因此其被普遍使用于汽車發(fā)動機(jī)、重型機(jī)械等產(chǎn)品上，并具有很好地使用效果。</p><p

小號螺栓。晉德螺栓</p><p style="text-indent:25px">目前我國常用的螺桿材料有45號鋼、40Cr、氨化鋼、38CrMOAl，高溫合金等。 1）45號鋼便宜，加工性能好，但耐磨耐腐蝕性能差。熱處理：調(diào)質(zhì)HB220—270，高頻淬火HRC45--48。 2）40Cr的性能優(yōu)于45號鋼，但往往要鍍上一層鉻，以提高其耐腐蝕耐磨損的能力。但對鍍鉻層要求較高，鍍層太薄易于磨損，太厚則易剝落，剝落后反而加速腐蝕，已較少應(yīng)用。熱處理：調(diào)質(zhì)HB220—270，鍍硬鉻HRC>553）氮化鋼、38CrMoAl綜合性能比較優(yōu)異，應(yīng)用比較普遍。一般氮化層達(dá)0．4—0．6毫米。但這種材料抵抗氯化氫腐蝕的能力低，且價(jià)格較高。 3）高溫合金材料優(yōu)于其它材料，該材料不用鍍層，主要用于注塑機(jī)生無鹵螺桿，該材料抗氧化耐腐蝕性能高，熱處理hra55`60.晉德螺栓</p><p
